  • 00:00Fortnight yeah we can see out
  • 00:03the window behind you looks
  • 00:05nice. So why don't we get started?
  • 00:08And I know there's still people joining us,
  • 00:11so to all those in attendance,
  • 00:14since those logging in welcome to a
  • 00:16special Cancer Center grand rounds
  • 00:18where you know very privileged to
  • 00:20honor the legacy of Doctor John Murnan,
  • 00:23have a very special guest as our
  • 00:252000 two 1020 Memorial Lecture,
  • 00:28and I want to introduce where I
  • 00:30herbs whose everyone knows is
  • 00:32our chief of Medical Oncology and
  • 00:34Associate Cancer Center director
  • 00:36for a translation of science and.
  • 00:38Leader of our lungs.
  • 00:40For, among other things,
  • 00:41to speak about the lectureship
  • 00:43and introduce our speaker.
  • 00:45So Roy, thank you,
  • 00:46thanks Charlie and thanks
  • 00:47everyone for joining.
  • 00:49This is a very special lecture because it
  • 00:51honors our colleague and friend John Urine.
  • 00:54If we can go to the next slide,
  • 00:56please.
  • 00:59Emily. So many people who are on the line,
  • 01:05new John I see John Sister Mary
  • 01:07Kay is on and his wife Nancy and
  • 01:10perhaps others are the family.
  • 01:11One of the special things about
  • 01:13this lecture is we usually can get
  • 01:16together and talk and in person.
  • 01:18Hopefully that will happen again next year.
  • 01:20But no, John was a very special person
  • 01:23and as many of us know he passed away in
  • 01:262005 of Melanoma at the young age of 47.
  • 01:29He was an associate professor
  • 01:30of medicine at the at Yale.
  • 01:32He was the director of the outpatient
  • 01:34center director of the Lung Cancer Clinic.
  • 01:36I wouldn't probably be here at Yelp,
  • 01:38not for John and Co.
  • 01:40Leader of the Experimental Therapeutics
  • 01:41program at the Yale Cancer Center.
  • 01:44He was survived by his wife Nancy,
  • 01:46his son John,
  • 01:48his mother Jean and I know that
  • 01:50Nancy is here and maybe Gene no.
  • 01:53Many new new John even better than me.
  • 01:56I knew him from from the clinical
  • 01:59trials and from meetings.
  • 02:01He was really the consummate
  • 02:03medical oncologist.
  • 02:04Academically, he was just the most caring,
  • 02:06position and active laboratory
  • 02:08working to develop new treatments.
  • 02:10Very insightful and really the
  • 02:12top program that we have today.
  • 02:15Is in large part due to John in his effort.
  • 02:18He had some efforts to his family
  • 02:20with in Las Vegas and Yell had some
  • 02:23interactions there for awhile,
  • 02:24but really he just was someone that
  • 02:27we all knew and loved and one of
  • 02:29the reasons we've invited today's
  • 02:31speaker is not only is she an amazing
  • 02:34researcher and clinician lung cancer,
  • 02:36but she knew him as well through the
  • 02:38cogs where John was a major person.
  • 02:41So really very glad to have this lecture.
  • 02:43I gave this lecture 11 years ago
  • 02:46so it's really a pleasure to
  • 02:48introduce today's speaker.
  • 02:49We can go to the next slide, please.
  • 02:51So in thinking about this,
  • 02:54you know this is the second time
  • 02:56we've scheduled this with Heather
  • 02:58and we just decided we would do this
  • 03:00virtually because we were so lucky to.
  • 03:03Heather agreed to come and speak with us.
  • 03:06Doctor Heather Wakelee is a professor
  • 03:08of medicine and the interim chief in
  • 03:10the Division of Oncology at Stanford
  • 03:12University and the President elect
  • 03:14of the International Association
  • 03:15for the Study of Lung Cancer.
  • 03:17PS When she received her medical
  • 03:20degree from Johns Hopkins University
  • 03:22and completed offer postgraduate
  • 03:25training at Stanford University
  • 03:27before joining the faculty in 2003.
  • 03:29Heather specializes in the
  • 03:31treatment of lung cancer,
  • 03:33thymoma and mesothelioma,
  • 03:34and had developed research programs
  • 03:36related to lung cancer in SOMA across
  • 03:39multiple areas including clinical trials,
  • 03:41translation, working, population Sciences.
  • 03:43He's the principal investigator.
  • 03:44Numerous clinical trials that
  • 03:46have changed the pattern of care,
  • 03:48and as a faculty director of the
  • 03:51Stanford Cancer Clinical Trials Office
  • 03:52and lead investigator for Ikago,
  • 03:54Akron Clinical Trials Group at Stanford.
  • 03:57He also is active in many organizations,
  • 03:59but actually I've shared many
  • 04:01patients with her.
  • 04:02She's also the most compassionate
  • 04:03physician and the person that
  • 04:05I would call whenever I
  • 04:06have a difficult case,
  • 04:08especially in the go far field.
  • 04:09In fact, I did that last night,
  • 04:12so if you go to the next slide we
  • 04:14normally at this point I would
  • 04:16be handing Heather her plaque,
  • 04:18but due to the amazing efficiency
  • 04:19of Yale Cancer Center,
  • 04:21Heather hasn't show us.
  • 04:23And so it already arrived.
  • 04:26Can you see it? So here we
  • 04:28go and then last night we actually
  • 04:30had a little get together.
  • 04:32Some of us on zoom and you
  • 04:34can see Pam Kuntz there.
  • 04:36Who we recruited out of Heathers Group
  • 04:39and we did a little zoom happy hour
  • 04:41and without drinks but just talked
  • 04:43about John talked about lung cancer.
  • 04:46So Heather it's wonderful to
  • 04:47have you here today.
  • 04:49Thank you to them.
  • 04:50You're in family for your support
  • 04:52and again and we Miss John so
  • 04:55much but we're looking forward to.
  • 04:57His memory to a wonderful
  • 04:59lecture from Heather Wakelee,
  • 05:0015 years of advances in EGFR
  • 05:02mutant lung cancer, Heather,
  • 05:04welcome to Yell.
  • 05:06Thank you, thanks right for
  • 05:08that very kind introduction for
  • 05:10inviting me to be here today.
  • 05:11I really wish I could be there
  • 05:13in person to get to visit with
  • 05:16all of you toward the campus,
  • 05:18which I haven't seen in a few years.
  • 05:20I know there's been a lot of lot of
  • 05:23development an I really would have
  • 05:25valued getting to meet with the family.
  • 05:27As Roy mentioned, I did know John,
  • 05:29I was pretty early in my career,
  • 05:31but he was very welcoming when I
  • 05:33showed up at the Kage Akron meanings.
  • 05:36I remember having several
  • 05:37conversations with him.
  • 05:38And I very vividly remember when
  • 05:40I heard of his death and how
  • 05:43devastating that was for me.
  • 05:45For whole lung cancer community.
  • 05:47And so when Roy invited me to
  • 05:49give this talk and I was thinking
  • 05:52about what could I cover,
  • 05:54thought about the fact that we lost
  • 05:57John 15 years ago and thought about
  • 05:59how much the world of lung cancer
  • 06:02therapy has changed during that time.
  • 06:05Ann wanted to use the story
  • 06:07with EGFR lung cancer is.
  • 06:09As a real example of one of the
  • 06:11most dramatic changes that have
  • 06:12happened during that time period.
  • 06:14But I also wanted to weave in
  • 06:17a different story and that was
  • 06:19about patient communication,
  • 06:20and so I'm also going to be talking
  • 06:23about that and framing it a little
  • 06:26bit around another physician who
  • 06:28unfortunately lost to cancer and who
  • 06:30has a connection to yell as well.
  • 06:33And that's Paul Community and his
  • 06:35breath when breath becomes air book,
  • 06:37I was I was his physician,
  • 06:40and in that book he talked a lot about
  • 06:43his philosophy about living as a.
  • 06:45Well, first of all,
  • 06:47is being a care provider physician
  • 06:49for patients facing cancer and
  • 06:51other serious issues.
  • 06:52But then as a patient and how he
  • 06:54thought about living as a patient
  • 06:57an he really captured a lot of
  • 06:59the ways I think about things.
  • 07:01And as we talked together and so
  • 07:04I wanted to share that as well.
  • 07:06So I'm going to try to do over the next hour.
  • 07:10I'm going to go ahead and share my
  • 07:13screen here. And give you the talk.
  • 07:18OK, and.
  • 07:20View slideshow OK,
  • 07:22so hopefully you're seeing this
  • 07:24now show I titled this 15 years of
  • 07:27advances in EGFR mutant non small
  • 07:29cell lung cancer lung cancer and then
  • 07:32with the focus on patient communication,
  • 07:34these are my disclosures.
  • 07:36And then as I thought about
  • 07:38a learning objectives,
  • 07:39it was to really talk about how that
  • 07:42EGFR Field has evolved overtime,
  • 07:44specifically the EGFR Tkis,
  • 07:45and then a couple of things.
  • 07:47We're looking at adding to Egypt art
  • 07:49therapy and then talk about communication.
  • 07:52So when we think about advances
  • 07:55in the treatment, EGFR,
  • 07:56TKI eyes alone, veg F combinations,
  • 07:59each diff are combinations,
  • 08:01chemotherapy, immune therapy,
  • 08:02and then the communication.
  • 08:04So back in 2000 and I was just
  • 08:07starting my time as a oncologist.
  • 08:09This was the state of the art and what this
  • 08:12is showing is survival curve from a
  • 08:14trial where patients were treated
  • 08:16with only things we knew to use which
  • 08:19was just chemotherapy combinations
  • 08:20and you can see that we hadn't
  • 08:23made a whole lot of progress.
  • 08:24We were helping people,
  • 08:26but not for nearly long enough,
  • 08:28and without really being able to
  • 08:30distinguish what was the best
  • 08:31treatment for any given patient.
  • 08:33Because all of these different chemotherapy
  • 08:35combinations looked about the same.
  • 08:37But many people realize that there
  • 08:39were things about lung cancer that
  • 08:42were different than some normal tissue,
  • 08:44and one of them was a high expression
  • 08:46of this EGFR or epidermal growth
  • 08:48factor receptor protein,
  • 08:50and what this cartoon is showing
  • 08:52is that the epidermal growth factor
  • 08:54receptor is a protein. It's a receptor.
  • 08:56It's on the cell surface and it's
  • 08:59sitting out there with the GF binding to it.
  • 09:02And then it sets off a whole bunch
  • 09:05of signaling,
  • 09:05which does a lot within the cell regarding.
  • 09:08Growth of cells. Survival of cell.
  • 09:10So it was thought that each day Fr
  • 09:12was likely pretty important in lung cancer,
  • 09:15and you'll notice one of these
  • 09:17reviews was written by Roy.
  • 09:19And so people develop different
  • 09:21ways to target EGFR,
  • 09:23the most common being these
  • 09:25tyrosine kinase inhibitors.
  • 09:26So this is the tyrosine
  • 09:28kinase receptor ligands,
  • 09:29binds and then you get signaling down
  • 09:32here and the tyrosine kinase domain.
  • 09:35So these medications that are pill
  • 09:37drugs oral can block that tyrosine
  • 09:40kinase activity than the first of
  • 09:43these developed was to fit Nip.
  • 09:45And I'm going to talk about each
  • 09:47of these drugs a little bit,
  • 09:49but there are other strategies
  • 09:50to hit tyrosine kinases.
  • 09:51One is to block where the leg and
  • 09:53would bind and will talk about
  • 09:55a couple of drugs that do that,
  • 09:57and then another is to just take all
  • 09:59the Ligue and what would be binding
  • 10:01and turning things on and remove it.
  • 10:03And that's a different approach
  • 10:04that used as well.
  • 10:05So just wanted to give this
  • 10:07cartoon to set people in mind about
  • 10:09thinking how the drugs work.
  • 10:10So the first drug to fit him and
  • 10:12you see Doctor Herbst of course
  • 10:13was involved in that was given
  • 10:15to patients with lung cancer.
  • 10:17And it was noted that some people,
  • 10:19maybe 10%, had these dramatic responses,
  • 10:21which was really exciting.
  • 10:22But we didn't know how to select them.
  • 10:25And this led to a larger trial with
  • 10:27a similar drug called or lot nib,
  • 10:29where patients receive this drug in the
  • 10:32second or third line or they got placebo.
  • 10:34And when you looked at it,
  • 10:36response rates were about 10%.
  • 10:37Survival wasn't great,
  • 10:38but it was better than placebo and so
  • 10:41this was really exciting at the time.
  • 10:43To see that two month improvement.
  • 10:45But what was really interesting
  • 10:47is people notice that it wasn't
  • 10:49just random who was responding.
  • 10:51It tended to be women attended
  • 10:53the people with the adenocarcinoma
  • 10:54type of lung cancer,
  • 10:56and especially people who had lung cancer,
  • 10:58who had never smoked,
  • 11:00and also notice that a lot of
  • 11:02them were of Asian ethnicity,
  • 11:04and so this led to at the
  • 11:06study known as the ipass trial,
  • 11:08which was conducted in Asia.
  • 11:10It was done in people who had
  • 11:12very limited smoking history,
  • 11:13but who had developed
  • 11:15adenocarcinoma lung cancer.
  • 11:16And this ended up being mostly women,
  • 11:18and they were randomized to either get the
  • 11:21EGFR pill drug you fit nib or chemotherapy,
  • 11:24and I showed you that before the
  • 11:26chemotherapy drugs are all about the same.
  • 11:29When we look at them.
  • 11:31And what was interesting is
  • 11:33when the results came out,
  • 11:34it was very confusing at first,
  • 11:36because when you look at the
  • 11:38progression free survival,
  • 11:39which is the time either that
  • 11:41someone is no longer alive or
  • 11:43that their tumor has started
  • 11:44to grow the progression time,
  • 11:46these curves kind of crossed in.
  • 11:48The chemo was looking better
  • 11:49until about five months,
  • 11:51six months and then the gym fit
  • 11:53nib so it wasn't very clear story.
  • 11:55And when we looked at overall survival
  • 11:57there wasn't any different so it wasn't
  • 11:59clear that this definitive drug was really.
  • 12:02Do anything special but.
  • 12:06Well,
  • 12:06that study was being conducted,
  • 12:08so starting at around 2005 and
  • 12:11again this is the 15 year story.
  • 12:14Scientists at several institutions.
  • 12:16An realize that these patients
  • 12:18who had these dramatic responses
  • 12:20they did testing on their tumors,
  • 12:22and they found that the tumors had a
  • 12:25change in the Egypt far protein that
  • 12:27was really related to a mutation that
  • 12:30had happened in the cancer cells.
  • 12:32So in the cancer cells,
  • 12:34EGFR became mutated and became
  • 12:35turned on all the time.
  • 12:37Constitu Tively active,
  • 12:38and that looked like it was
  • 12:40what was driving the cancer,
  • 12:42'cause none of those mutations
  • 12:43were found in the tumors are
  • 12:46patients who didn't respond.
  • 12:47But they were found in almost
  • 12:49every tumor of patient,
  • 12:50who did respond,
  • 12:51and so that led to sort of the
  • 12:53ah ha moment that changed how we
  • 12:55think about treating lung cancer,
  • 12:57because when they went back and tested
  • 12:59the tumor samples from the patients
  • 13:01who had been on the I pass trial,
  • 13:03they were able to come up with a
  • 13:05very different story that patients
  • 13:06whose tumors had the EGFR mutation
  • 13:08did much better with your fitness,
  • 13:10much higher responses.
  • 13:11It worked for much longer than chemo,
  • 13:13but for people whose tumors
  • 13:15did not have that,
  • 13:16even though they otherwise look the same.
  • 13:19It didn't work at all,
  • 13:20and that was the first moment for us in
  • 13:23lung cancer to realize we needed to look.
  • 13:25We couldn't just determine based on
  • 13:27what the patient looked like or what
  • 13:29their tumor look like under the microscope.
  • 13:31We needed to test,
  • 13:32and if we could find the EGFR mutation,
  • 13:35then we could actually treat the tumors
  • 13:37differently and have better outcomes.
  • 13:38And I'm focusing on EGFR today,
  • 13:40but we now know to think about and
  • 13:42look for mutations in seven different
  • 13:44genes in lung cancer is actually
  • 13:46closer to 10 now, but we have 7 where
  • 13:48we have FDA approved medications
  • 13:50and we can think about using those
  • 13:52instead of chemotherapy upfront.
  • 13:53So this was a complete revolution in how
  • 13:56we think about treating lung cancer,
  • 13:58and this study really was what God is there.
  • 14:01So I'm focusing on that quite
  • 14:03a bit in this particular trial,
  • 14:06by selecting the way they did,
  • 14:08about 60% of patients had EGFR
  • 14:10mutations and those numbers vary
  • 14:12around the world and based on who the
  • 14:14person is who's gotten the cancer,
  • 14:16but it's not specific dress to women in Asia,
  • 14:20have alot of my patients here in California,
  • 14:22wouldn't fit that demographic.
  • 14:24But yet there tumor hasn't EGFR mutation,
  • 14:26and they respond as if anybody else who
  • 14:30has that EGFR mutation in their tumor.
  • 14:33We've now had multiple other studies
  • 14:36that have looked at giving EGFR TK I
  • 14:39drugs versus chemo in patients whose
  • 14:42tumor have in Egypt are mutation
  • 14:44and you can see that in all of them,
  • 14:48the progression free survival time was much,
  • 14:51much better with the Egypt far drug,
  • 14:54but it wasn't forever,
  • 14:56and that's because we get resistance and
  • 14:59this is a slide goes back a little bit now,
  • 15:03but. Was figured out was that.
  • 15:05In order for a cancer to have an EGFR
  • 15:08mutation that we don't know why that happens,
  • 15:11we're still trying to figure that out.
  • 15:13But when the tumor has
  • 15:15that easier for mutation.
  • 15:17The tumors respond really well
  • 15:19to an EGFR tyrosine kinase drug,
  • 15:21but overtime resistance develops
  • 15:23because new mutations happen,
  • 15:25and in the setting of EGFR with
  • 15:27these initially developed EGFR drugs,
  • 15:30most of the time when those stopped working,
  • 15:33it was because another EGFR mutation
  • 15:35developed, and that was called T790M.
  • 15:38So we spent many years trying to
  • 15:40figure out a way to treat T790M.
  • 15:43I have a lot of old studies that
  • 15:46didn't go anywhere.
  • 15:48And many medications we worked
  • 15:49with but then came along this drug.
  • 15:52Oh, summer NAMM.
  • 15:53Which is the third generation EGFR drug.
  • 15:56And it works when T790M is there.
  • 15:58So what these are showing is you've
  • 16:01got the line.
  • 16:02If you've got lines above it,
  • 16:04that means that the tumors grew,
  • 16:06but everything below the line means
  • 16:08that the tumor shrunk so you can see
  • 16:11that for most of these the tumors were
  • 16:13shrinking when a patient received
  • 16:16oh summerton. If after they die.
  • 16:18Already had either the jefit neighbor
  • 16:20alot nip those so if they've been
  • 16:22on a first generation drug and it
  • 16:24stopped working.
  • 16:25And then they took this third
  • 16:27generation drug osimertinib most
  • 16:29of the time the tumor shrunk,
  • 16:30and that's because we were actually
  • 16:33getting that T790M target.
  • 16:34So to prove that there was a trial
  • 16:37for patients who had been found
  • 16:39to have Egypt permutation in their
  • 16:41tumor at the beginning,
  • 16:43they started on a first or
  • 16:45second generation EGFR medicine,
  • 16:46and then when it stopped working,
  • 16:48they were on a trial randomized
  • 16:51to either ghetto smart
  • 16:52nib or to get chemotherapy.
  • 16:54And what this showed us was that
  • 16:57progression free survival was
  • 16:58clearly better with, uh, oh, summer.
  • 17:00New versus the chemotherapy.
  • 17:02So it became standard that you would
  • 17:04test when someone was diognosed if
  • 17:07their tumor had the EGFR mutation,
  • 17:09you would start them on
  • 17:11our lot nib or defend him,
  • 17:13and when that stopped working,
  • 17:15if the T790M mutation was there then,
  • 17:17oh, Smyrna was a better choice
  • 17:19than going with the chemotherapy.
  • 17:22But finding the T790M wasn't perfect,
  • 17:24so there were several different
  • 17:26ways to do that.
  • 17:28You could either look with tissue.
  • 17:31Or in the blood with plasma testing.
  • 17:33And we also did some urine testing,
  • 17:35but we don't do that so much anymore
  • 17:37and what this is showing is that most
  • 17:40of the time you could find that T790M
  • 17:42in the tissue and in the plasma,
  • 17:44but there were sometimes you
  • 17:46could only find it in that issue.
  • 17:48And that's because it wasn't
  • 17:50being shed out into the DNA wasn't
  • 17:52going out into the blood.
  • 17:54Or you only found in the plasma,
  • 17:56and that's perhaps because
  • 17:57when you did the biopsy,
  • 17:59you didn't get enough of the cancer cells,
  • 18:01or there's some heterogeneity meeting
  • 18:03that not all of the cancer cells change
  • 18:05at the same time in the same way,
  • 18:08so you can have areas that are
  • 18:10resistant because of this mutation.
  • 18:11Other areas that are not,
  • 18:13and so I'm not going to go
  • 18:15into that today in one hour.
  • 18:17You can't cover everything,
  • 18:18but I wanted to at least mention
  • 18:20this because it is important
  • 18:22to know that when you have.
  • 18:24Cancer.
  • 18:24It's evolving overtime an the
  • 18:26way that we find out more about
  • 18:28it as we need to sample it.
  • 18:29An historically that was always with tissue.
  • 18:31But now we can look at it with
  • 18:33these plasma tests as well,
  • 18:34but that's all I'm going to
  • 18:37say on that topic.
  • 18:38OK,
  • 18:38so we know to test we know to
  • 18:41give a first generation drugs.
  • 18:43We know T790M develops.
  • 18:44So then you use the third generation drug.
  • 18:48But of course people wondered.
  • 18:49Why don't we just give this
  • 18:51third generation drug 1st and
  • 18:53then T790M won't develop?
  • 18:55So that was this flora trial
  • 18:57where patients who are newly
  • 18:59diagnosed and found to have EGFR
  • 19:02mutation either goto summer nib
  • 19:04or got a first generation drugs.
  • 19:06And that study clearly showed
  • 19:08that to Smyrna was better for
  • 19:10that progression free survival,
  • 19:12meaning that it took longer
  • 19:14before the cancer started to grow.
  • 19:16However,
  • 19:16it also led to overall survival improvement,
  • 19:19and that's because even though
  • 19:21theoretically if you started on
  • 19:23a first generation drugs and
  • 19:25then developed resistance,
  • 19:26you could go on to Summerton
  • 19:28if if it was T790M.
  • 19:31There are other things that cause
  • 19:33resistance an so delaying that time
  • 19:35to resistance with the osimertinib,
  • 19:36even when it's not resistance due to
  • 19:39T790M overall survival was better,
  • 19:41and so this has become the
  • 19:43standard approach in the US.
  • 19:44But unfortunately as you see,
  • 19:46these curves eventually do come down.
  • 19:48We're not curing people,
  • 19:49and therefore we still need to
  • 19:52think about better things to do.
  • 19:54So we kind of summarize
  • 19:55this first part about EGFR.
  • 19:57We need to test to find the Jaffar mutation,
  • 20:00and usually that's done
  • 20:01with the tissue testing.
  • 20:02But we can also sometimes find it
  • 20:04in the plasma with blood testing.
  • 20:06If you find the Jaffar mutation,
  • 20:08we start on an EGFR.
  • 20:10TKI osimertinib is what
  • 20:11we tend to use in the US,
  • 20:13but there are multiple other EGFR
  • 20:15tyrosine kinase drugs which are
  • 20:17approved in the US and globally,
  • 20:19and so those are still used as well.
  • 20:23And as I mentioned,
  • 20:24we're still thwarted by resistance.
  • 20:26So with Osimertinib,
  • 20:27it's not such a simple story like
  • 20:29it is with the 1st generation drugs,
  • 20:31where we get one resistance pathway,
  • 20:34which is that T790M resistance as
  • 20:35the predominant one when there's
  • 20:37osimertinib resistance are a lot of
  • 20:39different things that can happen.
  • 20:41You can get other EGFR mutations and C.
  • 20:44797 and T 797 S is the most common of those,
  • 20:47but there are a lot of other pathways
  • 20:50that can go be abnormal as well.
  • 20:53And so it's quite complex,
  • 20:54and there's a lot of research
  • 20:57being done there.
  • 20:58And this is just a graphic showing
  • 21:00some of those resistances,
  • 21:02so I talked about the T790M here
  • 21:04with first and second generation.
  • 21:07But there's also overexpression of
  • 21:09met and mutations in other genes and
  • 21:11also a transformation to small cell,
  • 21:13so it's not always straightforward.
  • 21:15And then with Osama RNIB there
  • 21:18can be changes in what the EGFR.
  • 21:20Just kind of percentage of expression
  • 21:22of the protein is it's never gone
  • 21:24that Egypt permutations never gone,
  • 21:26but the way it's expressed is different.
  • 21:28But you also can have met overexpression
  • 21:31is fairly common, or changes in BRAF.
  • 21:33We just were talking about a
  • 21:35case this morning.
  • 21:36Stanford, with another patient
  • 21:37who had been on no smart Niman,
  • 21:40then developed in be reputation and many,
  • 21:42many others.
  • 21:43So again, it's quite complex as we
  • 21:45talk about bypass tracks in Egypt,
  • 21:47our target alterations.
  • 21:48So then what do you do?
  • 21:50You gotta think.
  • 21:51Outside of that, here's the target.
  • 21:53Hit the target.
  • 21:54We've got to be broader that.
  • 21:56Here's a target hit.
  • 21:57The target is great,
  • 21:58and it's helped people tremendously
  • 21:59for an extended period of time.
  • 22:01But we want to extend it even further.
  • 22:04So what can we do?
  • 22:05We try something else so
  • 22:07we have anti angiogenesis.
  • 22:08Is one of those,
  • 22:09and that's getting at the fact
  • 22:11that in order for some tumor
  • 22:13cells to grow into a tumor,
  • 22:14they need to have blood vessels to feed them.
  • 22:17And so this is angiogenesis.
  • 22:18And that's where we get.
  • 22:20Drugs such as Bevis is a map and many others,
  • 22:23and there's been a ton of trials
  • 22:26noticing that in the EGFR setting,
  • 22:28veg F is also very important,
  • 22:30and so a lot of trials looking at in a
  • 22:33patient with Egypt or mutant lung cancer,
  • 22:36you can give the EGFR medicine,
  • 22:38but you can also give it with anti
  • 22:40veg F therapy and that theoretically
  • 22:42should make a big difference.
  • 22:44So one of the first trials was the beta
  • 22:47trial led by Doctor Herbst an in this study.
  • 22:50It wasn't selected for patients with
  • 22:53EGFR mutation because this was done
  • 22:55before we knew about the EGFR mutations
  • 22:57and we were just giving our lot nib to
  • 23:00people after they already had chemo.
  • 23:02But this showed that even without that,
  • 23:04giving the bevacizumab added to the
  • 23:07Erlotinib improved progression free
  • 23:08survival Anne in the small group of
  • 23:10patients who would went back and found
  • 23:13that they actually had an EGFR mutation.
  • 23:15There was a signal that there might
  • 23:17even be an overall survival benefit by
  • 23:20adding the beva system up to her latinum.
  • 23:23So there's been multiple other trials.
  • 23:25This was a phase two study done in Japan,
  • 23:28where patients with EGFR mutant lung
  • 23:31cancer received either or lot nib
  • 23:33the pill everyday or a lot in it.
  • 23:35Plus the breakfast is a Babin
  • 23:37beverages and Maps and antibody.
  • 23:39It's given Ivy every three weeks,
  • 23:41and this study showed a marked
  • 23:43improvement in progression free survival.
  • 23:45This actually led to approval
  • 23:47of this combination in Europe,
  • 23:49but not in the US.
  • 23:51With longer term follow-up, though,
  • 23:53it turned out that Despite that huge
  • 23:55progression free survival benefit,
  • 23:57there was no overall survival benefit,
  • 23:59and so it's a little bit unclear what
  • 24:02we're doing with this combination.
  • 24:05Perhaps it's helpful to prolong the time
  • 24:07that there are lot name stops working.
  • 24:10It turns out that if you're on
  • 24:12our lot nib and bevacizumab,
  • 24:14the most common resistance
  • 24:15pathway still is that T790M.
  • 24:17So if you're on this combination
  • 24:19and then resistance develops,
  • 24:20you can go on to get the oh,
  • 24:23Smyrna, but there are other things
  • 24:25that happen besides T790M and
  • 24:27then no overall survival benefit,
  • 24:28so little bit unclear.
  • 24:30There was a randomized phase three trial,
  • 24:33also done in Japan,
  • 24:34which had very similar results in Nice
  • 24:36progression free survival benefit,
  • 24:37but no overall survival benefit.
  • 24:39And this is news.
  • 24:40This just was presented at our ASCO
  • 24:42meeting in June of 2020 show we were
  • 24:45waiting on this and now we kind of
  • 24:47seeing this similar story emerging,
  • 24:49but it's more complex than that in the US.
  • 24:52We also have this or lot inhibin
  • 24:54Rammus serum app,
  • 24:55so I showed at the very beginning.
  • 24:58The different ways to target
  • 24:59these tyrosine kinase.
  • 25:01So the first where the tyrosine
  • 25:03kinase inhibitors which work in the
  • 25:05cell at the tyrosine kinase domain.
  • 25:07But then I also showed two different
  • 25:09strategies for antibodies,
  • 25:10one the bevacizumab type or its
  • 25:12binding to the leg and so sucking
  • 25:15all the leg and away the other binds
  • 25:18to the receptor and sort of blocks.
  • 25:20The way the receptor works oramus
  • 25:22serum AB is blocking veg F receptor.
  • 25:25So you've got our Latin if the
  • 25:27tyrosine kinase inhibitor blocking.
  • 25:29The tyrosine kinase activity
  • 25:30and then veg F Knotty Jeff
  • 25:32but Jeff related is also being blocked,
  • 25:34so you get a blockage that way and you see
  • 25:37this nice progression free survival benefit.
  • 25:39But we haven't seen the
  • 25:41overall survival data yet.
  • 25:42This combination is approved as
  • 25:44an option in the United States,
  • 25:46but I think that we're waiting to
  • 25:48see what that overall survival
  • 25:50data is going to look like.
  • 25:52Now I've talked about her Latin appear,
  • 25:55but you're thinking the beginning.
  • 25:56You were telling me that Osimertinib
  • 25:58is preferred over these.
  • 26:00So what?
  • 26:00Where is the oh summer nimbuses
  • 26:03amount data will hear some of it.
  • 26:05So this was data that Hanyu and the
  • 26:07Memorial Sloan Kettering Group put together.
  • 26:09This is not randomized.
  • 26:11This is just patients getting
  • 26:12oh smart nib and bevacizumab,
  • 26:14and the toxicity was manageable
  • 26:16and the response rate was very
  • 26:18high at 80% and the median time to
  • 26:20win the drugs combination stopped
  • 26:22working was about 19 months.
  • 26:24So that's interesting.
  • 26:25It's not overwhelming,
  • 26:26but interesting.
  • 26:27However, there is this very confusing
  • 26:29presentation that we saw just last month,
  • 26:32two months ago now in September
  • 26:34at the ESMO meeting the 2020,
  • 26:36which was a randomized phase,
  • 26:38two of oh Smyrna plus or minus bevacizumab,
  • 26:41again done in Japan.
  • 26:42And when you look at this,
  • 26:45the blue line is actually the
  • 26:47osimertinib alone.
  • 26:48So in this particular trial,
  • 26:50the combination of oh Summerton
  • 26:51Bevis is a map looked worse
  • 26:53for progression free survival.
  • 26:55Then just the ocean alone.
  • 26:57So that's a little bit confusing.
  • 27:00The ultimate number alone progression
  • 27:01free survival was lower than were well.
  • 27:04I should say this was done second line,
  • 27:06so this was for patients who
  • 27:08had or lot nip or just fitting.
  • 27:11It already had developed T790M
  • 27:12and then went on Osimertinib.
  • 27:14So it's different than the first line data.
  • 27:17But in this trial with no smart net plus
  • 27:20or minus bevacizumab in the second line.
  • 27:23The awesome art never alone
  • 27:24outperformed the combination.
  • 27:25Now this is a randomized phase two trial,
  • 27:28so we have to be careful,
  • 27:30sometimes randomized phase two
  • 27:31studies don't give us the truth.
  • 27:33This study did show that the
  • 27:35response to the combination was
  • 27:37higher than the single drug,
  • 27:39but just not that progression
  • 27:40free survival benefit.
  • 27:41So we're kind of confused by this result.
  • 27:44We are moving forward with the next
  • 27:46line of exploring this though,
  • 27:48so this is a randomized phase
  • 27:50study randomised three study in
  • 27:52the Kaga Chrome network.
  • 27:53Led by Helena, you and bless Hamas.
  • 27:55And this is for patients who
  • 27:57have just been diagnosed.
  • 27:58So the one I just showed you with
  • 28:01second line. This is first line.
  • 28:03Patients just diagnosed with lung
  • 28:05cancer that has an EGFR mutation and
  • 28:07they're going to get oh smart nib
  • 28:09plus or minus bevacizumab in the study.
  • 28:11Just opened to enrollment,
  • 28:13so we have no data yet,
  • 28:15but we're excited to participate,
  • 28:16though again,
  • 28:17as we talk about this option with patients,
  • 28:20it will be important to talk
  • 28:21about the data that
  • 28:23we've already seen.
  • 28:24With the other combinations of EGFR,
  • 28:26TKI plus or minus a veg F drug,
  • 28:29so we're still kind of
  • 28:30trying to understand this,
  • 28:32and there's also a no smart nib
  • 28:35romanisti remap trial ongoing.
  • 28:36OK, so leaving that and now on too,
  • 28:40so hopefully you're following EGFR TK alone.
  • 28:44EGFR TK I plus or minus.
  • 28:46These anti angiogenesis drugs.
  • 28:48And now we're looking at Egypt,
  • 28:50far EGFR combinations and this is
  • 28:52where we're looking at, an EGFR,
  • 28:55TKI pill, plus an antibody drug that's
  • 28:57also hitting that EGFR approaching.
  • 28:59And if you think again about that first
  • 29:02slide I showed you or early on where
  • 29:05you've got the different strategies.
  • 29:07If you've got a receptor tyrosine
  • 29:10kinase inhibitor tyrosine kinase,
  • 29:11if you block at the tyrosine kinase domain.
  • 29:14But you also block at that receptor point.
  • 29:17You're hitting the same protein in two ways,
  • 29:19and so that's the theory
  • 29:21behind why this would work.
  • 29:22And long ago.
  • 29:24Before we had to simmer
  • 29:26nib so going back in time.
  • 29:28We had a combination of an EGFR pill drug
  • 29:32afatinib plus in Egypt are antibody,
  • 29:34so tux,
  • 29:35omab and this combination was the first
  • 29:38combination and the first thing we
  • 29:40ever saw that worked in the setting of
  • 29:44having been on a first generation drugs.
  • 29:46Developing T790M,
  • 29:47so before we add anything else,
  • 29:50this combination worked and so
  • 29:52this was the original publication.
  • 29:55And again,
  • 29:55this is a waterfall plot,
  • 29:57so you see a few patients had
  • 29:58there's tumors grow,
  • 29:59but a lot of patients had
  • 30:01their tumors shrink,
  • 30:02and so this was an option
  • 30:03that we had for awhile.
  • 30:05But now we don't use it too much because of,
  • 30:08oh, Smyrna,
  • 30:08but we're coming back to study it.
  • 30:11And so there are combinations.
  • 30:12Nauvo summer nib.
  • 30:14Plus and different Egypt
  • 30:16for antibody necitumumab.
  • 30:17So we are part of this California
  • 30:20Cancer Consortium study.
  • 30:21Jonathan Rhys has talked about
  • 30:23some of the preliminary data at
  • 30:25ASCO last year and more ongoing
  • 30:28show encouraging information here,
  • 30:29and this is being looked at for
  • 30:32patients who have already been on oh
  • 30:35smart nib and it stopped working or early on.
  • 30:38There also combinations with afatinib
  • 30:40and necitumumab and were part of
  • 30:43that consortium which is, uh.
  • 30:44Vanderbilt,
  • 30:45so a lot of work still looking at this,
  • 30:48but some toxicity issues so we'll
  • 30:50see how that pans out there.
  • 30:53Also,
  • 30:53newer drugs being developed at
  • 30:55build on this so one is this
  • 30:57aim of antonyms drug which is
  • 30:59a combination of EGFR antibody.
  • 31:01It's also hitting met,
  • 31:03so if you were paying close attention,
  • 31:05you'll notice I mentioned met as
  • 31:07a potential resistance mechanism,
  • 31:09and so there's data to support
  • 31:11looking at met.
  • 31:12There have been a lot of trials
  • 31:15looking at specific met inhibitors.
  • 31:17In the Egypt Far world again,
  • 31:19I only have an hour,
  • 31:20so I couldn't go into all of that.
  • 31:23They haven't really gone too far yet.
  • 31:25We haven't changed our treatment,
  • 31:27but we haven't forgotten about that.
  • 31:29So we're looking at Egypt.
  • 31:30Are met antibody,
  • 31:31hear them if antonym in combination
  • 31:33with the different third generation
  • 31:35drug lizard nip and to this was
  • 31:37dated that was just presented at Asmo,
  • 31:39which was encouraging,
  • 31:40showing that for patients who had already
  • 31:43had osimertinib in this preliminary
  • 31:44data about a third of those patients
  • 31:46did respond to this new combination.
  • 31:48So we'll see how that pans out.
  • 31:51How long it works,
  • 31:52what the toxicity is show there's
  • 31:54there is movement in excitement
  • 31:56about new combinations.
  • 31:58There are also newer EGFR
  • 32:00pathway or this is the new drug.
  • 32:03Use U Three 1402 or projection
  • 32:05map directed hand and this drug
  • 32:07is looking at her three and
  • 32:10you're confused now because you
  • 32:12think you're talking about EGFR.
  • 32:14Why, you talking bout her three?
  • 32:17Well, EGFR is also called her one,
  • 32:20so her one an heard too and her
  • 32:23three are all in the same family and
  • 32:26they do interact with each other.
  • 32:29Show this antibody drug conjugate
  • 32:31that's focused on her three there's
  • 32:34hope and some data now showing that
  • 32:36it could be active in the setting
  • 32:39where there's Egypt far drive.
  • 32:41Sorry, each of our driven lung cancer,
  • 32:44so this is again some very preliminary
  • 32:46data where they were looking at patients
  • 32:49who had EGFR mutant lung cancer had
  • 32:52previously received osimertinib or
  • 32:54had developed resistance to or lot in a
  • 32:57bridge of fitness and didn't have T790M.
  • 33:00And again on this waterfall plot you can see.
  • 33:04That there have definitely been some
  • 33:06responses and the details here all about.
  • 33:08Well, what was the resistance mechanism?
  • 33:10What was the underlying you do fermentation?
  • 33:12What resistance was seen?
  • 33:14And so there's a lot to parse through here,
  • 33:17which I won't go into.
  • 33:18But encouraging new data.
  • 33:21OK.
  • 33:21So now we talked about Egypt Party K eyes
  • 33:24alone veg F novelly Jeff combinations.
  • 33:27And now I'm going to switch to chemo
  • 33:30and talk about Egypt, Kaizen, chemo.
  • 33:32So again, bear with me here.
  • 33:34This is a it's a lot to go through,
  • 33:37but there's been so much we've been
  • 33:39exploring and trying to understand.
  • 33:41How do we do a better job of treating
  • 33:44patients with EGFR mutant lung cancer?
  • 33:46So what about combining chemotherapy?
  • 33:48Need you 40K as well?
  • 33:49When we first learned about the EGFR Tkis,
  • 33:52there were big trials.
  • 33:53Combining them with chemo misses the
  • 33:55tribute and talent studies and again,
  • 33:57Doctor Herbs played a big role in these.
  • 34:00And these studies were completely,
  • 34:01absolutely negative,
  • 34:02and this was done before we knew
  • 34:04about EGFR mutant lung cancer.
  • 34:06We were treating everybody the same,
  • 34:08but totally negative studies.
  • 34:10And so this let us to not really
  • 34:12think about this approach for awhile.
  • 34:15There was some work looking
  • 34:16at this intercalation idea,
  • 34:18where you would use the Jaffar TK.
  • 34:20I stop it, get the cell signaling again,
  • 34:23give the chemo,
  • 34:24restart the EGFR TKI and this
  • 34:26actually was encourage ING.
  • 34:28It showed an overall survival benefit.
  • 34:30But people don't really want
  • 34:31to be on chemo if
  • 34:33they can just take a pill and
  • 34:35said this was not widely adopted.
  • 34:37People looked at whether when you
  • 34:39were on a first generation EGFR
  • 34:41drug and it stopped working and
  • 34:43you were going to go to chemo.
  • 34:45This was before Osama Rname.
  • 34:47Whether you could continue the EGFR drug,
  • 34:50or if you should stop it.
  • 34:52And this was the impressed trial
  • 34:54and that didn't work either.
  • 34:55There was no benefit an if anything.
  • 34:58Survival favored stopping that Jeff
  • 34:59it nib and just going with chemo.
  • 35:02So we had these.
  • 35:03Big randomized trials combinations negative.
  • 35:05We had this trial negative.
  • 35:07If you combine the EGFR TK I
  • 35:09in the chemo together so not a
  • 35:11lot of enthusiasm but a lot of
  • 35:14questions still because the idea
  • 35:15of stopping in EGFR TKI for tumor
  • 35:18that was dependent on it doesn't
  • 35:20make a lot of sense to many people,
  • 35:23and so lots of debate on this.
  • 35:26And then we had two trials that
  • 35:28came out which changed again,
  • 35:30the way that we think about this.
  • 35:32Should this was a trial done in Japan,
  • 35:35chemotherapy.
  • 35:36Within Egypt Artique I so this was
  • 35:39in patients who are newly diagnosed
  • 35:41EGFR mutant lung cancer and they
  • 35:44either got the EGFR drugs if it new.
  • 35:47Or they got to fit in it plus chemo.
  • 35:49If they got your fitness plus chemo,
  • 35:51they stayed on maintenance and
  • 35:52at the time it stopped working.
  • 35:54They went on to other therapy.
  • 35:56If they got ripped fitness alone
  • 35:58when it stopped working,
  • 35:59they stopped it and went to chemo.
  • 36:01So it's sort of a.
  • 36:02You get everything together.
  • 36:03The chemo plus that huge.
  • 36:05If our drug or you get it sequentially,
  • 36:07EGFR and then chemo.
  • 36:09Again, no summerton period.
  • 36:10This was designed before there
  • 36:12was oh so Barnum.
  • 36:14An when you think about this was the.
  • 36:17First progression free survival.
  • 36:18So this was for patients who
  • 36:21had chemo plus to fit nib.
  • 36:23Versus Jeff it Nip and the chemo plus
  • 36:25your fitness group stayed on the drug longer.
  • 36:28It was they were still on it
  • 36:30for like 21 months.
  • 36:31The group only get into fitting.
  • 36:33It only worked about 11 months.
  • 36:35You like?
  • 36:35OK right but what you really want to
  • 36:37know is everybody everything together
  • 36:39concurrent versus sequential and when
  • 36:41you looked at everybody together,
  • 36:42concurrent versus sequential,
  • 36:43the sequential group cut up when they
  • 36:46went from there drifitng it to chemo.
  • 36:47It all ended up being the same
  • 36:50and you think OK, negative study.
  • 36:52Except overall survival actually
  • 36:53showed a benefit to having gotten
  • 36:55everything at the beginning,
  • 36:57so this has this a little bit confused.
  • 37:00Why would getting everything at the
  • 37:03beginning be better than the A and then B?
  • 37:06If the progression free
  • 37:07Survival's were the same,
  • 37:08so we're still trying to figure this out,
  • 37:10but there was another study
  • 37:12that was done in India.
  • 37:14Similar design.
  • 37:14That also showed that there
  • 37:16was a progression free and
  • 37:18an overall survival benefit.
  • 37:19This is a little bit different
  • 37:21'cause not everybody who
  • 37:22started on Jefit and I've
  • 37:24got the chemo afterwards,
  • 37:25but it kind of supports that,
  • 37:27and so they're ongoing trials.
  • 37:28Now looking at this question and
  • 37:29including a study with Osimertinib,
  • 37:31so we'll see how this pans out.
  • 37:34And now I'm going to shift gears
  • 37:36again and go to immune therapy because
  • 37:38that's the other big revolution
  • 37:40that's happened in the last 15 years,
  • 37:42but it hasn't changed each
  • 37:44of our lung cancer much.
  • 37:45When we look at the first trials
  • 37:47that got immune therapies with,
  • 37:49these are the PD One PD L1 checkpoint
  • 37:52inhibitors approved in lung cancer.
  • 37:54They were given second line to
  • 37:56people who had already had chemo.
  • 37:58Some of whom were Egypt Farhadi,
  • 38:00Jaffar lung cancer, and it already
  • 38:02had Egypt farland treatments as well.
  • 38:04They were the only subgroup that didn't
  • 38:06do well with the checkpoint inhibitor,
  • 38:08so in these older trials and
  • 38:10I'm looking here at this box.
  • 38:12Of docetaxel,
  • 38:14chemo versus checkpoint inhibitors.
  • 38:17Those trials showed overall
  • 38:19survival benefits to everybody.
  • 38:20With the checkpoint inhibitors,
  • 38:21except patients who had EGFR mutations.
  • 38:23So when we got to the bigger
  • 38:25trials in first line,
  • 38:27patients with EGFR mutations
  • 38:28weren't included on those trials,
  • 38:30so we have very little data.
  • 38:32This one study that came out
  • 38:34of the Atlantic trial,
  • 38:35which was a phase two study,
  • 38:37showed that if you had a Jaffar mutant
  • 38:40lung cancer and your PD L1 level was high,
  • 38:42sometimes the checkpoint inhibitors
  • 38:44worked about 12% of the time.
  • 38:46But if you had low,
  • 38:47any different mutation, it never worked.
  • 38:49People have done TK.
  • 38:51I plus immunotherapy combinations.
  • 38:53And they've been totally negative.
  • 38:54Alot of Texas city. No clear benefit so.
  • 38:58We don't get too enthusiastic about
  • 39:00checkpoint inhibitors in EGFR,
  • 39:02but we think about it.
  • 39:04There was one trial.
  • 39:05This empower 150 study that was chemo
  • 39:07plus bevacizumab plus immune therapy
  • 39:09that allowed for patients with EGFR
  • 39:11mutations and that study did show
  • 39:13potential survival benefit in the subset,
  • 39:16but we have to be really careful because
  • 39:19this was a small subset of a bigger study.
  • 39:22It wasn't really powered to
  • 39:24answer the specific question,
  • 39:25and so their ongoing trials.
  • 39:27Now looking at this so we
  • 39:28still have questions around.
  • 39:30What do we do with immune therapy
  • 39:32in the setting of EGFR lung cancer?
  • 39:34So to put all that together,
  • 39:36each of Arcgis improved response
  • 39:37rate and progression free survival
  • 39:39compared to first line chemotherapy.
  • 39:41But you have to test.
  • 39:42You have to know the Jaffar
  • 39:44mutation is there.
  • 39:45Oh, summer at numbers are preferred.
  • 39:46First line treatment from the floor of trial.
  • 39:49Veg F inhibition improves response
  • 39:51and progression free survival
  • 39:52when added DJ fourty keys.
  • 39:54But we don't know if it
  • 39:57improves overall survival.
  • 39:58Chemotherapy may improve overall survival
  • 40:00in combination with EGFR TK eyes,
  • 40:02but we're still trying to
  • 40:04answer that definitively.
  • 40:06And immune therapy activity is very,
  • 40:08very limited and there's a
  • 40:09lot we need to explore there,
  • 40:11and we're still dealing with the
  • 40:12fact that resistance develops.
  • 40:13So we've made tremendous progress.
  • 40:15But we still have a long way to go.
  • 40:18And that's where communication
  • 40:20is so important because some
  • 40:21patients do remarkably well.
  • 40:23I was meeting with one
  • 40:25of my patients yesterday.
  • 40:26I've been caring for for
  • 40:28eight years with metastatic,
  • 40:30EGFR, mutant lung cancer.
  • 40:31We're having to think about
  • 40:32her next line of treatment,
  • 40:33but she still on her last name,
  • 40:35but it's been eight years.
  • 40:37Some patients do remarkably
  • 40:38poorly on another patient.
  • 40:39I saw, I think it was last Thursday.
  • 40:42He's never had a good response to anything,
  • 40:44even though he has a clear EGFR
  • 40:46mutation in his lung cancer.
  • 40:48And so why are they different?
  • 40:49I can't tell, just based on the age
  • 40:52of permutations that they have there.
  • 40:54Other factors that we're
  • 40:55trying to understand,
  • 40:56but it's important than that when we
  • 40:58talk about how someone is going to do,
  • 41:00we're never too confident in that,
  • 41:02because we really don't know,
  • 41:04so we can often predict outcomes
  • 41:05that we can't always.
  • 41:07And we have to strive to keep the
  • 41:09trust of the patient and their family,
  • 41:12to help them relive given this uncertainty.
  • 41:15And so I mentioned,
  • 41:16I'm going to leave this in a little bit.
  • 41:19So this was when breath becomes
  • 41:21air written by Paul Kleanthi,
  • 41:23Yale medical student,
  • 41:24who then went on to do his
  • 41:26neurosurgical training at Stanford,
  • 41:28and he unfortunately died
  • 41:30of EGFR mutant lung cancer.
  • 41:31But while he was living with his disease,
  • 41:34he wrote this amazing book.
  • 41:36One of the quotes that I.
  • 41:38Lee love from this is that the
  • 41:41reason that doctors don't give
  • 41:43patients specific prognosis is
  • 41:45not merely because they cannot.
  • 41:48What patients seek is not scientific
  • 41:50knowledge that doctors hide
  • 41:52but existential authenticity.
  • 41:53Each person must find on his or
  • 41:56her own getting too deeply into
  • 41:59statistics is like trying to
  • 42:01quench a thirst with salty water.
  • 42:04The angst of facing mortality has
  • 42:07no remedy in probability and so.
  • 42:09That really captures the essence,
  • 42:11I think of what we tried to do
  • 42:12in this communication setting,
  • 42:14but written obviously far more
  • 42:16eloquently than I would ever
  • 42:18have been able to do.
  • 42:19And obviously we miss Paul very much.
  • 42:22So when we talk about communication tips,
  • 42:24these are a few of the things
  • 42:26that I like to think about.
  • 42:28One of them is about the numbers.
  • 42:30Just as Paul said,
  • 42:31but numbers to get remembered.
  • 42:32If you have an hour long conversation
  • 42:34with the patient and you mentioned a
  • 42:36number when they leave the conversation,
  • 42:38that's what they will remember.
  • 42:39So you have to be very careful
  • 42:41how you use them.
  • 42:43And be very careful how
  • 42:44prognosis is discussed.
  • 42:45Avoid codeine medians,
  • 42:46because if you quote a median again,
  • 42:48that's the only thing Tillman remembers.
  • 42:50Not everything we know about
  • 42:52what a median means.
  • 42:53She always give a range and I talk about.
  • 42:56The worst possible outcomes,
  • 42:58but I also talk about the best,
  • 43:00but whenever I talk about the best,
  • 43:02I always make sure I can
  • 43:04think of a specific
  • 43:05person who was there 'cause otherwise you're
  • 43:07just making a number up out of the air.
  • 43:10The prognosis for any individual
  • 43:12of course evolves overtime,
  • 43:13so help the patient to
  • 43:14understand that and their family,
  • 43:16and then try to guide the patient
  • 43:18in making life decisions.
  • 43:19They need to make based on probabilities
  • 43:21of how much time they have,
  • 43:23knowing that there's that uncertainty
  • 43:25encouraging patients to think
  • 43:26about the things they need to do,
  • 43:28and also about what they want to do.
  • 43:31It's really a terrible thing if
  • 43:33someone assumes that they have
  • 43:35many years left when they don't,
  • 43:37and therefore they don't do the things
  • 43:39they would have done if they had known
  • 43:42that they didn't have alot of time.
  • 43:44But it's also terrible to take
  • 43:46away hope from someone because
  • 43:48there always is that uncertainty,
  • 43:49so you try to guide but
  • 43:51leave uncertainty on going.
  • 43:53Dialogue is obviously critical.
  • 43:54I would bring up the concept of risk and
  • 43:57benefit in regard to therapy fairly early,
  • 43:59and I frequently talk about that when I'm.
  • 44:02Reviewing things because at some point
  • 44:04we are going to get to that point where
  • 44:06the risk of ongoing therapy is going
  • 44:09to outweigh the potential benefit.
  • 44:10And if you bring that up for the first time,
  • 44:13then it's a much more difficult conversation.
  • 44:16It's also really critical as you
  • 44:18engage the patient who is the
  • 44:20key person in all of this.
  • 44:21You've got to make sure the family also
  • 44:24knows what's going on and is aware of
  • 44:26the information that you're talking
  • 44:28about because the family is going to
  • 44:30live with the memory of the patient.
  • 44:32Forever.
  • 44:33And it's really important that there are
  • 44:35part of those decisions as much as possible,
  • 44:38not to guide the patient 'cause it
  • 44:40needs to be the patients choices,
  • 44:42but to understand how the patient was making
  • 44:45those choices and to be a part of that.
  • 44:47I think that really helps with the piece
  • 44:49for the family as they continue living,
  • 44:51having lost an important loved one.
  • 44:54When having a Frank conversation,
  • 44:55pay careful attention to how you're being
  • 44:57heard harder now in the world of zoom.
  • 45:00Much easier when you're in a room
  • 45:02with someone and you can watch the
  • 45:04body language in their faces and
  • 45:05and make sure that everyone is
  • 45:07engaged in an understanding so that
  • 45:09you can back up and rephrase as
  • 45:11necessary to get everyone together.
  • 45:13Really important to check back in
  • 45:14with the family and the patient.
  • 45:16If you're making a decision.
  • 45:19To have everybody understand
  • 45:20why that decision was made.
  • 45:21While we're choosing a particular
  • 45:23therapy or another,
  • 45:24because it's not always going to work,
  • 45:26and it's important that everybody knows how
  • 45:28we ended up making that decision together.
  • 45:30If you hear a really strong
  • 45:32objection to a particular treatment,
  • 45:34it's always good to ask why there are
  • 45:36a lot of stories that people have
  • 45:38based on their own experiences of
  • 45:40family members experiences someone
  • 45:42they heard about bad experience.
  • 45:44To understand why what the particular
  • 45:46patients facing is either similar or
  • 45:48different that can help a lot too.
  • 45:50If it all possible,
  • 45:51never answer your phone or pager
  • 45:53when you're in with the patient.
  • 45:55100% attention really matters,
  • 45:56no matter how crazy are
  • 45:57busy things are in clinic,
  • 45:59and for those of us who are commissioned,
  • 46:01you walk out of the exam room.
  • 46:03We got five people talking with
  • 46:05you about different things you're
  • 46:06trying to process all of that,
  • 46:08but when you go back in the exam room,
  • 46:10you just have to be there 100%.
  • 46:12Com you're listening and that
  • 46:14really makes a big difference.
  • 46:15Also, because the really the key
  • 46:17is being sure that the patient
  • 46:19and the family know that you care
  • 46:21about your patient as a person.
  • 46:22And that you are guiding them
  • 46:24to make the best decisions that
  • 46:26can help them live as long as
  • 46:28possible with good quality of life.
  • 46:30And I'm going to and then with
  • 46:32a quote from Joe Feldman,
  • 46:34who's amazing patient advocate
  • 46:36within the EGFR world.
  • 46:37And she does a lot with the ice,
  • 46:40else she is a frequent speaker
  • 46:42at our conferences,
  • 46:43including our North America conference.
  • 46:45And we were just there together
  • 46:47a few weeks ago,
  • 46:48and she talked about treating the
  • 46:50whole patient on an intellectual,
  • 46:52physical, and emotional level.
  • 46:54We need to know that the doctor
  • 46:56caring for us as a patient cares
  • 46:59about us what we patients value
  • 47:01can't be quantified in a curve.
  • 47:03Hazard ratios and clinical trial
  • 47:05numbers don't translate to real
  • 47:06life or capture the une quantifiable
  • 47:08meaning of a person's life show.
  • 47:10I thought she really,
  • 47:11really captured summed it up well with that.
  • 47:14OK, so overall summary.
  • 47:16Over the last 15 years,
  • 47:18we know that Egypt artique eyes
  • 47:20alone or the standard of care in a
  • 47:23patient with EGFR mutant lung cancer,
  • 47:25but you have to find the mutation.
  • 47:28Veggie combinations.
  • 47:29Encouraging,
  • 47:29but so far we haven't seen that
  • 47:32translate into overall survival benefit.
  • 47:35EGFR combinations look really promising,
  • 47:37but not standard yet.
  • 47:38Chemotherapy combinations maybe
  • 47:39will move into first line,
  • 47:41seemed to have improved overall survival,
  • 47:43but we haven't really bought that
  • 47:45concept yet. Immune therapy.
  • 47:46That's a promise for so many
  • 47:48patients living with lung cancer
  • 47:50and other cancers now.
  • 47:52But in the world of EGFR therapy,
  • 47:54there's a lot we don't understand yet.
  • 47:56And that brings us to the fact
  • 47:59that for all of these advances
  • 48:01and wonderful things that we do.
  • 48:04We still aren't caring people.
  • 48:05We still have a lot that we need to do.
  • 48:08I have intentionally not gone into.
  • 48:10What do we do in early stage?
  • 48:12Lung cancer therapy today?
  • 48:14'cause there's been some tremendous
  • 48:15advances there or with Theodore
  • 48:17trial and other ways of looking
  • 48:19at bringing in Egypt or therapy
  • 48:20earlier to those patients who
  • 48:22can theoretically be cured.
  • 48:23Today,
  • 48:23I wanted to really focus on
  • 48:25metastatic disease and the fact
  • 48:27that with all that we can do,
  • 48:29it still about communication
  • 48:30and really to help our patients
  • 48:32make the right choices for
  • 48:33themselves and to live.
  • 48:35Despite facing the uncertainties
  • 48:36of cancer, so thank you.
  • 48:43Oh, you're on mute Roy.
  • 48:46Thanks thanks Heather.
  • 48:47That was wonderful and really great to see.
  • 48:50The progress made in 15 years.
  • 48:52You know a lot of it, you know,
  • 48:54stimulated by the work of John and
  • 48:57others were open for questions now I
  • 48:59guess we do questions in the chat room.
  • 49:02I see Charlie here.
  • 49:03Maybe we'll start with a few.
  • 49:05Well, while you get while they come
  • 49:07in for the EGFR mutated lung cancer.
  • 49:10Of course you know you see a lot of it,
  • 49:13especially where you live because
  • 49:15it's so prominent in Asians.
  • 49:17Do we know yet why has anyone looked
  • 49:19at the genetics of that to understand
  • 49:22no other certain sequences or or
  • 49:24genetics that can explain that? So
  • 49:27it's a great question,
  • 49:28so there are multiple efforts on
  • 49:31going to try to answer that question.
  • 49:33So my last international trip before
  • 49:35travel ended was last January.
  • 49:37I was in Taipei, Taiwan.
  • 49:39James Gang had invited me to the National
  • 49:42Taiwan University and there are some.
  • 49:45There's amazing work being done there
  • 49:47in in multiple other Asian countries
  • 49:49trying to look at the nuances subtleties.
  • 49:52They've done a lot of screening as well.
  • 49:55That involves screening and non smokers
  • 49:57trying to figure out you know what
  • 49:59what's happening and they've very
  • 50:01clearly shown as significant increase
  • 50:03in adenocarcinoma of the lung in non
  • 50:06smokers and it's both in men and in women.
  • 50:09I'm actually working with the group
  • 50:11that's from UC Davis University,
  • 50:13California Davis University of California,
  • 50:15San Francisco and then Stanford.
  • 50:17We have a narrow one that's finding a
  • 50:19case control study that we're doing.
  • 50:22Looking at Asian never smoking women
  • 50:24who have developed lung cancer,
  • 50:25almost all of whom have EGFR mutants
  • 50:27mutations and then doing a match control
  • 50:30of very similar people who don't have
  • 50:32lung cancer and trying to see if what
  • 50:34we are able to find there and that of
  • 50:37course involves sample collections as well.
  • 50:39And there are a lot of
  • 50:41similar ongoing efforts,
  • 50:42but we don't know an for me here
  • 50:44in Northern California though,
  • 50:45a lot of my patience with you from you and
  • 50:48lung cancer are never smoking Asian women.
  • 50:51I also have a whole lot of.
  • 50:53People have multiple different ethnicities,
  • 50:54men and women.
  • 50:55Different age ranges who also have
  • 50:57each of our mutant lung cancer show.
  • 50:59It's not just that group,
  • 51:00but there's gotta be something 'cause
  • 51:02it does seem to be increasing and were
  • 51:04still baffled as to what that is.
  • 51:07Great, thanks for the next question.
  • 51:09We have a special guest 15 years
  • 51:10ago a young Scott Guettinger
  • 51:12came to Yale to work with Sean.
  • 51:14Sadly they only work together
  • 51:16for know about a year,
  • 51:17but if Scott turned out OK,
  • 51:19Jonathan done OK with you.
  • 51:21So Scott, I'm going to move over so I put
  • 51:23my mask on Scotts gonna ask alive question.
  • 51:26These are Dart leader in lung cancer.
  • 51:29To see you. Very talk I'm.
  • 51:31I don't think you got into it too much,
  • 51:34but I'm just curious.
  • 51:35For your patience to progress at multiple
  • 51:38sites while getting closer mitted,
  • 51:40do you continue who are not trial candidates?
  • 51:43Do you continue the those fermented
  • 51:45with the chemotherapy to stop it
  • 51:47along the lines of the impress trial
  • 51:49where we didn't see a benefit from
  • 51:52at least first generation TK eyes?
  • 51:54How do you handle that situation?
  • 51:56That's a great question, so obviously
  • 51:58it's different for different folks.
  • 52:00So first answer the first part of
  • 52:02question you didn't actually ask which
  • 52:04is if someone is progressing in a single
  • 52:07or a couple areas, we will continue.
  • 52:09Oh Smyrna bandu radiation.
  • 52:11Or other local ablative
  • 52:12therapy whenever possible,
  • 52:13and try to extend the time
  • 52:15that they're on that treatment.
  • 52:17If we get to a point where they
  • 52:20are definitely needing to switch
  • 52:22to a different systemic therapy.
  • 52:24Looking for trials first and foremost,
  • 52:26but if we can't and they're going
  • 52:28to switch to chemo, not on a trial.
  • 52:31It will depend on the patient.
  • 52:33If they have significant amount
  • 52:34of brain disease,
  • 52:35I will continue the OCE myrnam and
  • 52:37start them on the chemotherapy.
  • 52:39Continuing osimertinib for some
  • 52:40of the other patients.
  • 52:41I will stop it and part of my rationale
  • 52:44behind that is I watch them closely.
  • 52:46I do believe that flare can happen,
  • 52:48but it's pretty rare.
  • 52:49So if a patient suddenly gets drastically
  • 52:51worse when we stop the jiffi drug,
  • 52:54their back on it,
  • 52:55they stay on it.
  • 52:56I've had that happen more in people
  • 52:58with bone metastases and interesting Lee.
  • 53:00I think if you read when breath becomes air.
  • 53:03Paul was one of the people I continued
  • 53:05on and he never got to Summerton,
  • 53:07but I can't because he was his
  • 53:08disease was before that,
  • 53:09but I continued him on 'cause he was
  • 53:11someone who as soon as we stopped he
  • 53:13had bone pain so he was definitely
  • 53:15someone who flared so he never stopped.
  • 53:17But for other patients I will stop.
  • 53:19And part of the rationale is that by
  • 53:22stopping the EGFR TK on the patients
  • 53:24where you can and doing with chemotherapy,
  • 53:26the resistance that develops at that
  • 53:28point after they've been on chemo
  • 53:30for awhile tends to be much more
  • 53:32responsive to restarting and EGFR.
  • 53:33TK I in the context of a study
  • 53:35or some combination,
  • 53:37so that's while I'll think about it,
  • 53:39but a lot of my longer term patients
  • 53:41right now we don't stop because they've
  • 53:43had things where they've had bone,
  • 53:45Mets, or other problems so.
  • 53:48Thank you yeah. Great thanks Scott.
  • 53:51We have a few questions in the chat room.
  • 53:55Um? It's from Sarah Goldberg.
  • 53:59Hi Sarah, was with us last night.
  • 54:02You see any promising avenues
  • 54:04for using immunotherapy in each
  • 54:06year from you in lung cancer
  • 54:08patients beyond PD one agents? Oh,
  • 54:11great question Sarah.
  • 54:12So I'll again into the first part of that.
  • 54:17So with the checkpoint inhibitors
  • 54:19I've had a couple of patients who
  • 54:21have done very well with them.
  • 54:23They were patients tending to
  • 54:25VL 858 are not deletion 19 and
  • 54:27that's something that in Taiwan.
  • 54:29They've been looking at.
  • 54:30A lot also tended to have high PD,
  • 54:33L1, and so a couple folks
  • 54:36have done well and we are.
  • 54:38Participating in a study looking
  • 54:40at chemo with carboplatin.
  • 54:42Pemetrexed said bevacizumab
  • 54:43plus or minus a Tezos.
  • 54:46This is a multi site study.
  • 54:49So I think there might be room there,
  • 54:52but it's not something I'm doing
  • 54:53is often off trial as far as other
  • 54:56immunomodulatory modulators, yes,
  • 54:58but I'm not a good enough immunologist to
  • 55:00tell you exactly what that's going to be.
  • 55:03I think that it's something that
  • 55:05a lot of us are watching really
  • 55:07closely to try to understand what is
  • 55:10it that the simple explanation is EGFR?
  • 55:13Mutant lung cancer doesn't
  • 55:14have that many new antigens,
  • 55:16'cause it's not very complex tumor,
  • 55:18but then,
  • 55:18overtime.
  • 55:19Theoretically it gets more complex,
  • 55:20so there should be more NEO
  • 55:22antigens but really knew antigens.
  • 55:24Not all Neo antigens are the same,
  • 55:26and so I think that if we can figure
  • 55:28out what is it that can make that
  • 55:31cancer more identifiable to immune,
  • 55:33system will have ways to move forward.
  • 55:35But I don't think we've figured
  • 55:37that out very well yet,
  • 55:39so.
  • 55:41Great, we have one from Katie
  • 55:44Palitti who you know as well.
  • 55:46When I don't know if we can have
  • 55:48Katie give it live or question,
  • 55:50I don't know how to do that,
  • 55:52so I'll just ask it.
  • 55:53She, she says she's only at
  • 55:55one of the other leaders of
  • 55:57our sport program in EGFR.
  • 55:58Resistance does thank you for great lecture.
  • 56:00Heather grey talk.
  • 56:01I was wondering what you think
  • 56:02we should be thinking about to
  • 56:04address the heterogeneity of
  • 56:05resistance mechanisms that can
  • 56:06emerge in individual patients.
  • 56:08Great question Katie.
  • 56:09So I think that as much as the targeted
  • 56:12story is a beautiful story and to
  • 56:15be able to say we found the deletion
  • 56:1719 and we treat it with their lot
  • 56:20nib and then the T790M developed and
  • 56:22then we treated with those summerton.
  • 56:25If that only gets a so far and I
  • 56:27don't think we're ever going to
  • 56:29be able to really get completely
  • 56:31around that because as time goes on
  • 56:34there's more and more heterogeneity
  • 56:36in the resistance pathways.
  • 56:37Should we have to be?
  • 56:39Thinking about it,
  • 56:40you know the straightforward
  • 56:41answer right now.
  • 56:42Is chemotherapy 'cause that
  • 56:43doesn't really care so much about
  • 56:44what the resistance pathway was,
  • 56:45but it gets back to Sarah's question
  • 56:48that eventually we've got to figure
  • 56:49out how to get the immune system
  • 56:51to be able to recognize the cancer
  • 56:53and all of its various iterations.
  • 56:54As it becomes more resistant
  • 56:56and be able to tackle it.
  • 56:57I don't have an answer as to
  • 56:59how we're going to do that,
  • 57:00but to me that's really the only
  • 57:02way we're really going to get at it,
  • 57:04because were to get it early
  • 57:06enough that it hasn't had time to
  • 57:08develop all of the resistance,
  • 57:09and that's where the.
  • 57:10Earlier stage therapy is helpful so,
  • 57:12but even there I think that I don't
  • 57:14know that we're going to cure with
  • 57:16that approach because I think that
  • 57:18it only takes a few cells that become
  • 57:20resistant to then grow up again,
  • 57:22and so I think we've all got a lot of
  • 57:25years left of work that we need to
  • 57:27get doing to be able to make the impacts.
  • 57:30We'd like to make.
  • 57:32Right, and certainly by working
  • 57:34through the cooperative groups and
  • 57:36the societies and collaborating.
  • 57:38Given that this is a worldwide
  • 57:40disease so important.
  • 57:41We I don't see too many
  • 57:43more questions in the chat,
  • 57:45just about the end of the hour I see
  • 57:47Nancy nearing joined and I just want
  • 57:50to acknowledge her Johns wife and I'm
  • 57:52sorry we can't talk in person Nancy,
  • 57:54but next year hopefully will see
  • 57:56you in the front row and we can.
  • 57:58Zoomed Heather inferred picture but Curly
  • 58:01any any final thoughts before we end?
  • 58:04No, there was a fantastic talk.
  • 58:06I mean, get really outlines the
  • 58:08but so exciting in lung cancer,
  • 58:11both with respect to targeted
  • 58:13therapies an hopefully integrating
  • 58:15IO with these things.
  • 58:16Overtime.
  • 58:17So thank you is really powerful work.
  • 58:20And thanks for taking the time.
  • 58:22Thanks to everyone who joined.
  • 58:24We had a very large crowd today,
  • 58:26both because of you Heather and because
  • 58:29of John and we remember him fondly
  • 58:31and in his memory will continue to
  • 58:34take good care of our patients and
  • 58:36which was always number one goal
  • 58:38with the most innovative therapies.
  • 58:39Which is exactly what both are.
  • 58:41Cancer centers are trying to
  • 58:43do so thank you everyone and
  • 58:45see you soon. Thank you.
