A Phase 1b, Randomized, Open-Label Study of PEGylated Recombinant Human Hyaluronidase (PEGPH20) in Combination With Cisplatin Plus Gemcitabine and PEGPH20 in Combination With Atezolizumab and Cisplatin Plus Gemcitabine Compared With Cisplatin Plus Gemcitabine in Hyaluronan-High (HA-high) Subjects With Previously Untreated, Unresectable, Locally Advanced, or Metastatic Intrahepatic and Extrahepatic Cholangiocarcinoma and Gallbladder Adenocarcinoma

What is the purpose of this trial?

The study was conducted to assess the safety and tolerability of (1) polyethylene glycol (PEG) PEGylated Recombinant Human Hyaluronidase (PEGPH20) in combination with cisplatin (CIS) and gemcitabine (GEM) (PEGCISGEM), and (2) PEGPH20 in combination with CIS, GEM, and atezolizumab (PEGCISGEMATEZO).
