Phase 1/2 Study of PI-3K Inhibition With PX-866 Combined With Vemurafenib (BRAF Inhibitor) in Patients With BRAF-mutant Cancer Including Advanced Melanoma

The purpose of the phase 1 portion of the study is to determine the maximally tolerated dose (MTD) or recommended dose (RD) and the safety/tolerability of PX-866 in combination vemurafenib in patients with any advanced BRAF-mutant cancer. The purpose of the phase 2 portion of the study is to compare progression free survival (PFS), antitumor activity (response rate), disease control rate (DCR), and the safety and tolerability of PX-866 in combination with vemurafenib vs. vemurafenib alone in patients with advanced BRAF-mutant melanoma at the doses recommended from Phase 1.

NCT01616199 Advanced BRAF-mutant Cancers
MeSH: Melanoma
HPO: Cutaneous melanoma Melanoma

2 Interventions

Name: PX-866

Description: Phase 1 dose escalation: PX-866 in combination administered orally every day in 28-day cycles until progression or unacceptable toxicity. Phase 2 combination: PX-866 and vemurafenib administered every day in 28 day cycles until progression or unacceptable toxicity. Phase 2 single-agent: vemurafenib administered orally at labeled dose every day in 28 day cycles until progression or unacceptable toxicity.

Type: Drug
