A Phase I, Open-Label, Multicenter, Three-Period, One-Sequence Study to Investigate the Effect of Rifampin on the Pharmacokinetics of a Single Oral Dose of 960 mg of Vemurafenib

This open-label, multi-center, three-period, one-sequence study will investigate the effect of rifampin on the PK of vemurafenib in participants with unresectable BRAFV600-mutation positive metastatic melanoma or other malignant tumor type that harbors a V600-activating mutation of BRAF without acceptable standard treatment options.
