Phase II Trial of BRAF/MEK Inhibitors in Papillary Craniopharyngiomas

This phase II trial studies how well vemurafenib and cobimetinib work in treating patients with BRAF V600E mutation positive craniopharyngioma. Vemurafenib and cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Outcomes

Description: Defined as the number of responses achieved during treatment with BRAF and MEK inhibitors divided by the total number of evaluable patients and assessed by contrast-enhanced magnetic resonance imaging or computed tomography. Point estimates will be generated for response rates within each cohort with corresponding 95% binomial confidence intervals. Simon's two-stage design with one interim analysis for futility will be applied to evaluate response rate within each cohort.

Measure: Response rate

Time: Up to 5 years

Secondary Outcomes

Description: Will be summarized for each cohort within each cohort with Kaplan-Meier curves and estimates.

Measure: Progression-free survival

Time: Up to 5 years

Description: Will be summarized for each cohort within each cohort with Kaplan-Meier curves and estimates.
