Advanced Solid Tumor Clinical Trial
Official title:
A Phase 1, First-in-human, Open-label, Multicenter Study of JZP898 as Monotherapy and in Combination With Pembrolizumab in Participants With Advanced or Metastatic Solid Tumors
This Phase 1 first-in-human study will investigate the safety, tolerability, pharmacokinetics (PK), immunogenicity, and preliminary antitumor activity of JZP898 monotherapy as well as JZP898 in combination with pembrolizumab in adult participants with advanced or metastatic solid tumors.
