|Official Title:||Phase II Trial of BRAF/MEK Inhibitors in Papillary Craniopharyngiomas|
|Actual Study Start Date :||August 4, 2017|
|Estimated Primary Completion Date :||December 2021|
|Estimated Study Completion Date :||August 2026|
Experimental: Treatment (vemurafenib, cobimetinib)
Patients receive vemurafenib PO BID on day 1-28 and cobimetinib PO QD on days 1-21. Treatment repeats every 28 days for up to 5 courses in the absence of disease progression or unacceptable toxicity. Patients may then receive radiation therapy, surgery, or continued treatment with vemurafenib and cobimetinib at the discretion of the treating physician.
Other: Laboratory Biomarker Analysis
Other: Quality-of-Life Assessment
- Response rate [ Time Frame: Up to 5 years ]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.
- Progression-free survival [ Time Frame: Up to 5 years ]Will be summarized for each cohort within each cohort with Kaplan-Meier curves and estimates.
- Overall survival [ Time Frame: Up to 5 years ]Will be summarized for each cohort within each cohort with Kaplan-Meier curves and estimates.
