Clinical Trial Summary

The study is being conducted to assess the safety and tolerability of (1) PEGPH20 in combination with CIS and GEM (PEGCISGEM), and (2) PEGPH20 in combination with CIS, GEM, and atezolizumab (PEGCISGEMATEZO) compared with (3) cisplatin and gemcitabine (CISGEM).

Description:

The study will have a Run-in portion and an Expansion portion. The Run-in portion will be used to evaluate the safety profile of the PEGCISGEM and PEGCISGEMATEZO treatments prior to evaluating the efficacy and safety of PEGCISGEM and PEGCISGEMATEZO treatments compared with CISGEM treatment in the Expansion portion of the study.
