Clinical Trial 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.

Description:

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
