This Phase 1 study is comprised of dose escalation and cohort expansions for FPT155 monotherapy and for FPT155 in combination with pembrolizumab. Monotherapy dose escalation is designed with initial accelerated titration followed by a standard 3+3 dose escalation; combination dose escalation uses a standard 3+3 design. Patients will remain on study treatment until progression of disease, unacceptable toxicity, or other specified reason for discontinuation.
This study is a Phase 1 open-label, first-in-human, multicenter study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and activity of FPT155 as monotherapy in patients with advanced solid tumors.
