NCT01519323

Description:

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.

Vemurafenib	Experimental	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.	vemurafenib

             therapy prior to first administration of study drug

Maximum Eligible Age:	17 Years
Minimum Eligible Age:	12 Years
Eligible Gender:	All
Healthy Volunteers:	No

Primary Outcome Measures

Measure:	Maximum Tolerated Dose (MTD)/Recommended Dose
Time Frame:	Up to 28 days of treatment
Safety Issue:
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.

Secondary Outcome Measures

Measure:	Area Under the Concentration-Time Curve for Vemurafenib
Time Frame:	Pre-dose, 2, 4, 8, 12 hours post dose on Cycle 1 Day 1 and Cycle 1 Day 22 (each cycle is of 28 days)
Safety Issue:
Description:

Measure:	Number of Participants With an Adverse Event (AE)
Time Frame:	Up to approximately 2 years 11 months
Safety Issue:
Description:	An AE was defined as any untoward medical occurrence in a patient administered a pharmaceutical product and which did not necessarily have to have a causal relationship with study treatment.

Measure:	Best Overall Response Rate (BORR)
Time Frame:	Up to 2 years
Safety Issue:
Description:	BORR was assessed by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. BORR was defined as the number of participants who achieved a complete response (CR) or partial response (PR). CR was defined as complete disappearance of all target lesions and non-target disease. PR was defined as a >=30% decrease under baseline of the sum of diameters of all target lesions. BORR was summarized along with the associated exact 95% confidence interval (CI) using the method of Clopper-Pearson.

Measure:	Clinical Benefit Rate (CBR)
Time Frame:	Up to 2 years
Safety Issue:
Description:	CBR was defined as the number of participants that achieved a CR, PR or stable disease (SD) (SD for at least 6 weeks) as assessed by investigators according to the RECIST v1.1. CR was defined as complete disappearance of all target lesions and non-target disease. PR was defined as at >=30% decrease under baseline of the sum of diameters of all target lesions. SD was defined as steady state of disease with neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD).

Measure:	Progression-free Survival (PFS)
Time Frame:	Randomization date of first subject until disease progression or death or which ever occur first (2 years)
Safety Issue:
Description:	PFS was defined as the time between the day of first treatment and the first documentation of progressive disease or death. Progression was defined as a 20% increase in the sum of the longest diameter of target lesions, the appearance of new lesions and increase of at least 5 mm in the sum of diameters of target lesions. Participants who were withdrawn from the study without documented progression were to be censored at the date of the last known tumor assessment when the participant was known to be progression free. Median PFS was estimated using Kaplan-Meier method and 95% CI for median was computed using the Brookmeyer and Crowley method.

Measure:	Overall Survival (OS)
Time Frame:	Randomization date of first subject until death (2 years)
Safety Issue:
Description:	Overall survival was defined as the time between the date of first treatment to the date of death, regardless of the cause of death. Participants who were alive at the time of the analysis were censored at the date of their last being known alive. Median overall survival was estimated using Kaplan-Meier method and 95% CI for median was computed using the Brookmeyer and Crowley method.
