Brief Summary

This phase II Pediatric MATCH trial studies how well vemurafenib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with BRAF V600 mutations that have spread to other places in the body (advanced) and have come back (recurrent) or do not respond to treatment (refractory). Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with vemurafenib with advanced solid tumors (including central nervous system \[CNS\] tumors), lymphomas or histiocytic disorders that harbor activating BRAF V600 mutations.

SECONDARY OBJECTIVES:

I. To estimate the progression free survival in pediatric patients treated with vemurafenib with advanced solid tumors (including CNS tumors), lymphomas or histiocytic disorders that harbor activating BRAF V600 mutations.

II. To obtain information about the tolerability of vemurafenib in children with relapsed or refractory cancer.

EXPLORATORY OBJECTIVE:

I. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).

OUTLINE:

Patients receive vemurafenib orally (PO) twice daily (BID) on day 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)From enrollment to the end of treatment, up to 2 years

ORR will be defined as complete response + partial response and assessed by Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Will be calculated as the percent of evaluable patients who are responders, and confidence intervals will be constructed using the Wilson score interval method.

Secondary Outcome Measures
NameTimeMethod
Progress Free Survival (PFS)From the initiation of protocol treatment to the occurrence of any of the following events: disease progression or disease recurrence or death from any cause, assessed up to 5 years

PFS will be defined as time from the initiation of protocol treatment to the I of any of the following events: disease progression or disease recurrence or death from any cause. Patients with local calls of disease progression (i.e. calls made by the treating institution), will be counted as having had an event, even if the central review does not declare progression. PFS along with the confidence intervals will be estimated using the Kaplan-Meier method.

Percentage of Patients Experiencing Grade 3 or Higher Adverse EventsFrom enrollment to 30 days after the end of treatment, up to 2 years

Percentage of patients experiencing grade 3 or higher adverse events will be evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. All patients who receive at least one dose of protocol therapy will be considered in the evaluation of toxicity.
