Atezolizumab (anti-programmed cell death 1 ligand 1 [PD-L1]) was evaluated in combination with PEGylated recombinant human hyaluronidase (PEGPH20).In 2 randomized MORPHEUS trials, eligible patients with advanced, previously treated pancreatic ductal adenocarcinoma (PDAC) or gastric cancer (GC) received atezolizumab plus PEGPH20, or control treatment (mFOLFOX6 or gemcitabine plus nab-paclitaxel [MORPHEUS-PDAC]; ramucirumab plus paclitaxel [MORPHEUS-GC]). Primary endpoints were objective response rates (ORR) per RECIST 1.1 and safety.In MORPHEUS-PDAC, ORRs with atezolizumab plus PEGPH20 (n = 66) were $6.1\%$ $(95\%$ CI, $1.68\%-14.80\%)$ vs. $2.4\%$ $(95\%$ CI, $0.06\%-12.57\%)$ with chemotherapy (n = 42). In the respective arms, $65.2\%$ and $61.9\%$ had grade 3/4 adverse events (AEs); $4.5\%$ and $2.4\%$ had grade 5 AEs. In MORPHEUS-GC, confirmed ORRs with atezolizumab plus PEGPH20 (n = 13) were $0\%$ $(95\%$ CI, $0\%-24.7\%)$ vs. $16.7\%$ $(95\%$ CI, $2.1\%-48.4\%)$ with control (n = 12). Grade 3/4 AEs occurred in $30.8\%$ and $75.0\%$ of patients, respectively; no grade 5 AEs occurred.Atezolizumab plus PEGPH20 showed limited clinical activity in patients with PDAC and none in patients with GC. The safety of atezolizumab plus PEGPH20 was consistent with each agent's known safety profile.
