Brief summary

This open-label, multi-center study will evaluate the safety, tolerability, and pharmacokinetics of RO5212054 \[PLX3603\] in participants with BRAF V600-mutated advanced solid tumors. Cohorts of participants will receive escalating oral doses of RO5212054. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

Interventions

DRUGRO5212054

Participants will receive RO5212054 at a starting dose of 200 milligrams (mg) orally once daily in each 21 day cycle. Dose levels for escalation will be decided based on the safety assessment of previous cohort. Dose escalations in increments of 50-100 percent are planned.
