A Study of PEGylated Recombinant Human Hyaluronidase (PEGPH20) With Pembrolizumab in Participants With Selected Hyaluronan High Solid Tumors

Study involves dose escalation phase (completed in Nov-2016) to assess the safety and tolerability of PEGPEM (PEGylated recombinant human hyaluronidase \[PEGPH20\] combined with pembrolizumab \[Keytruda®\]) and to find the recommended Phase 2 dose (RP2D) ; and an expansion phase to assess the efficacy, safety and tolerability of PEGPEM in stage III b/IV NSCLC and relapsed/refractory GAC participants. Plan was to include approximately 51 HA-high participants (30 NSCLC and 21 GAC participants) in the dose expansion phase on the obtained RP2D from dose escalation phase of the study.
