Phase 1, First-in-Human, Multicenter, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Antitumor Activity of KO-2806 When Administered as Monotherapy and in Combination Therapy in Adult Patients With Advanced Solid Tumors

Description

This first-in-human (FIH) dose-escalation and dose-validation/expansion study will assess KO-2806, a farnesyl transferase inhibitor (FTI), as a monotherapy and in combination, in adult patients with advanced solid tumors.
