Phase I/IIa Study to Evaluate the Safety, PK, PD, and Preliminary Efficacy of PLX8394 in Patients With Advanced Cancers.
The study objective is to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of orally administered PLX8394 in patients with advanced solid tumors. An additional objective is to identify a Recommended Phase 2 (RP2D) for further evaluation in the Extension Cohorts (Phase IIa portion).
The study objective of the Extension Cohorts (PART 2 portion) is to assess the objective tumor response and the PK, PD, and safety of PLX8394 when the RP2D is used in patients with advanced BRAF-mutated cancers.

|Official Title:||A Phase I/IIa Study to Assess the Safety, Pharmacokinetics, and Pharmacodynamics of PLX8394 in Patients With Advanced, Unresectable Solid Tumors|
- Phase 1 dose escalation: Identification of Recommended Phase 2 Dose Safety of PLX8394 [ Time Frame: 1 Year ]Physical examinations, vital signs, 12-lead electrocardiograms, adverse events, hematology, serum chemistry, and urinalysis will be used to assess safety and tolerability.
- Identification of Recommended Phase 2 dose (RP2D) [ Time Frame: 1 year ]Study drug administration is dosed continuously until clinically significant disease progression, discontinuation of study for any reason or one of the stopping criteria is met.
