Sequential VCN-01 plus durvalumab was better tolerated than concomitant treatment. The recommended VCN-01 phase 2 dose (RP2D) was 1.0E13 vp, on the sequential schedule. Encouraging survival was observed in patients after progressing on anti-PD-(L)1 agents. Data supports VCN-01 replication associated with increased PD-1, PD-L1, and CD8 tumor expression. Sequential systemic delivery of VCN-01 and anti-PD-L1 therapy may represent an improved treatment for HNSCC.

Importantly, mTOR inhibitors synergistically enhanced the antitumor effects of stroma-targeting PEGPH20 in vivo in pNETs. Overall, this study revealed that cancer cell-derived ApoE could induce TipECs to remodel the TSR and that mTOR inhibitors could increase the efficacy of stroma-targeting therapies. Secretion of ApoE by pancreatic neuroendocrine tumor cells engenders a stroma-rich microenvironment, which can be reversed with mTOR inhibitors as part of combination strategies targeting the tumor stroma.
