A Study of Vemurafenib And GDC-0973 in Patients With BRAF-Mutation Positive Metastatic Melanoma

This study is ongoing, but not recruiting participants.

Last updated: December 1, 2015
Last verified: December 2015
This open-label, dose-escalation study of vemurafenib in combination with GDC-0973 will evaluate the safety, tolerability and pharmacokinetics in patients with BRAF V600 mutation-positive metastatic melanoma. Patients with previously untreated, BRAFV600E mutation-positive, locally advanced/unresectable or metastatic melanoma or those who have progressed on vemurafenib monotherapy immediately prior to enrolling in this trial are eligible. Patients will be assigned to different cohorts with escalating oral doses of vemurafenib and GDC-0973. The anticipated time on study treatment is until disease progression, unacceptable toxicity or any other discontinuation criterion.

Drug: vemurafenib
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Official Title: A Phase IB, Open-Label, Dose-Escalation Study Evaluating the Safety, Tolerability and Pharmacokinetics of Vemurafenib in Combination With GDC-0973 When Administered in BRAFV600E Mutation-Positive Patients Previously Treated (But Without Prior Exposure to BRAF or MEK Inhibitor Therapy) or Previously Untreated for Locally- Advanced/Unresectable or Metastatic Melanoma or Those Who Have Progressed After Treatment With Vemurafenib
