Phase 1/2 Dose-Escalation and Expansion Study of FLX475 Alone and in Combination With Pembrolizumab in Advanced Cancer

This clinical trial is a Phase 1/2, open-label, sequential-group, dose-escalation and cohort
expansion study to determine the safety and preliminary anti-tumor activity of FLX475 as
monotherapy and in combination with pembrolizumab.

The study will be conducted in 2 parts, a dose-escalation phase (Part 1) and a cohort
expansion phase (Part 2). In Part 1 of the study, subjects will be enrolled in sequential
cohorts treated with successively higher doses of FLX475 as monotherapy or in combination
with pembrolizumab. In Part 2 of the study, subjects will be initially enrolled in Stage 1 of
parallel expansion cohorts of FLX475 as monotherapy or in combination with pembrolizumab.
