Description

Summary

This is a multicenter, open-label, phase I/II basket study, evaluating the safety, tolerability, RP2D, pharmacokinetics, pharmacodynamics and antitumor activity of EOS-448 (also known as GSK4428859A or belrestotug) combined with standard of care and/or with investigational therapies in participants with advanced solid tumors.

Official Title

A Multicenter, Open-Label, Phase I/II Study of EOS884448 (EOS-448) in Combination With Standard of Care and/or Investigational Therapies in Participants With Advanced Solid Tumors

Details

The combinations evaluated will be:

  • EOS-448 combined with pembrolizumab, an anti-PD-1 antibody
  • EOS-448 combined with inupadenant an investigational adenosine A2A receptor antagonist
  • EOS-448 combined with dostarlimab an anti-PD-1 antibody
  • inupadenant combined with dostarlimab
  • EOS-448 combined with inupadenant and dostarlimab
  • EOS-448 combined with dostarlimab and standard of care chemotherapies in participants with NSCLC
