Summary
Brief summary (as posted)
This open-label, multicenter. single arm Phase I dose-escalation study with efficacy tail extension will evaluate the maximum tolerated dose/recommended dose, the safety and efficacy of vemurafenib (RO5185426) in pediatric participants (aged 12 through 17) with newly diagnosed or recurrent surgically incurable and unresectable Stage IIIC or Stage IV melanoma harboring BRAFV600 mutations. Participants will receive vemurafenib orally twice daily until disease progression or unacceptable toxicity occurs.

- description
- Participants received vemurafenib into two separate cohorts with different starting doses based on greater than or equal to (\>=)45 kilogram (kg) and other weighing less than (\<)45 kg. The starting dose for participants (\>=45 kg) was 720 milligram (mg) of vemurafenib by mouth twice daily (BID) and the next dose level for participants in this cohort was 960 mg by mouth BID. The starting dose level for participants weighing \<45 kg was to be 480 mg of vemurafenib by mouth BID, but no participants were enrolled into this cohort.

Primary outcomes (1)
- measure
- Maximum Tolerated Dose (MTD)/Recommended Dose
- timeFrame
- Up to 28 days of treatment
- description
- The MTD was defined as the dose level at which six evaluable participants had been treated and at most one participant experienced a dose limiting toxicity (DLT) and the next highest dose level was too toxic. Dose escalation occurred if 0 out of 3 or at most 1 out of 6 participant experienced DLT while being treated at a dose level; otherwise the dose was declared unsafe and thus above the MTD.
