Summary

This first-time-in-human (FTIH) study will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary clinical activity of escalating doses of GSK6097608 given as monotherapy and in combination with dostarlimab in participants with advanced solid tumors. This study will be used to define the recommended Phase 2 dose (RP2D). The study comprises 3 phases; screening phase (28 days prior to first dose), treatment phase (until disease progression, unacceptable toxicity, death, or withdrawal of consent) and follow-up phase (90 days). Approximately 100 adult participants with locally advanced, recurrent, or metastatic solid tumors will be enrolled.
