A Study of NPX887 for Participants With Solid Tumors Known to Express B7-H7/HHLA2

Summary

NPX887 is a human, antagonistic immunoglobulin G1 (IgG1) monoclonal antibody targeting B7-H7 (HHLA2) that may potentiate an anti-tumor immune response. The goal of this first-in-human study is to learn whether NPX887 is safe and tolerable and shows a preliminary efficacy in participants with B7-H7 (HHLA2) expressing tumors at selected dose(s). The main questions it aims to answer are: * what is an appropriate dose to be given to participants? * are the side effects of treatment manageable? * what is the preliminary anti-tumor activities? Participants who are treated will receive an intravenous (IV) infusion of NPX887 if their disease has not progressed, and be closely monitored by the treating physicians.
