Description

This is a Phase 1, open-label, multi-center study whose principal Part 1 stage objective is to determine the recommended Phase 2 dose (RP2D) of the anti-PVR monoclonal antibody (mAb) as a single agent and combined with the anti-PD-1 mAb pembrolizumab in patients with advanced solid malignancies.

In the Part 2 stage, the antitumor activity of NTX-1088 alone or combined with pembrolizumab will be evaluated in patients with malignancies known to express PVR.
