What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

You may need to stop taking certain medications. If you are on medications that are strong CYP3A4 inducers or inhibitors, or CYP1A2 substrates, you must stop them at least 14 days before joining the study.

How is the drug combination of Vemurafenib and Cobimetinib unique for treating craniopharyngioma?

The combination of Vemurafenib and Cobimetinib is unique for treating craniopharyngioma because it specifically targets the BRAF-V600E mutation found in the papillary variant of this tumor, offering a non-surgical option that avoids the serious risks associated with surgery and radiotherapy, such as blindness and cognitive impairment.12345

What data supports the effectiveness of the drug combination Vemurafenib and Cobimetinib for treating craniopharyngioma?

Research shows that the combination of Vemurafenib and Cobimetinib is effective in treating patients with BRAF-mutant papillary craniopharyngioma, leading to significant tumor reduction and improved neurological outcomes.12367

Are You a Good Fit for This Trial?

This trial is for patients with a specific brain tumor called BRAF V600E mutation positive craniopharyngioma. Eligible participants must have measurable disease, may or may not have received prior surgery, and should not have had previous treatment with BRAF or MEK inhibitors. Women of childbearing potential need a negative pregnancy test to participate.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive vemurafenib orally twice daily on days 1-28 and cobimetinib once daily on days 1-21. Treatment repeats every 28 days for up to 5 courses.

20 weeks

Follow-up

Participants are monitored for disease progression or unacceptable toxicity. Patients with disease progression are followed up every 16 weeks for 2 years, and all other patients are followed up every 6 months for 5 years.

What Are the Treatments Tested in This Trial?

Interventions

  • Cobimetinib
  • Vemurafenib
Trial Overview The effectiveness of two drugs, vemurafenib and cobimetinib, is being tested on stopping the growth of this type of brain tumor by blocking enzymes needed for cell growth. The study will assess how well these drugs work together in treating this condition.
How Is the Trial Designed?
1Treatment groups
Experimental Treatment
Group I: Treatment (vemurafenib, cobimetinib)Experimental Treatment4 Interventions
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.

Published Research Related to This Trial

Vemurafenib combined with cobimetinib has shown effectiveness in treating patients with BRAF-mutant papillary craniopharyngioma, a type of brain tumor.
This combination therapy targets specific mutations, suggesting a tailored approach to treatment that could improve outcomes for affected patients.
BRAF-MEK Inhibition Is Effective in BRAFV600E-Mutant Papillary Craniopharyngioma.[2023]
A patient with a BRAF-V600E mutant papillary craniopharyngioma showed significant tumor reduction and neurological improvement after treatment with a combination of BRAF and MEK inhibitors (dabrafenib and trametinib) following unsuccessful radiation therapy.
Despite the successful tumor response, the patient experienced permanent panhypopituitarism, highlighting the need to consider potential long-term side effects of this treatment approach.
BRAF-V600E mutant papillary craniopharyngioma dramatically responds to combination BRAF and MEK inhibitors.Roque, A., Odia, Y.[2018]
A 35-year-old man with a BRAF-V600E-positive papillary craniopharyngioma experienced a remarkable 95% reduction in tumor size over 21 months while being treated with the BRAF-V600 inhibitor dabrafenib and trametinib, indicating the efficacy of this targeted therapy.
The treatment was well-tolerated with no negative side effects reported, suggesting that BRAF-V600E inhibition could be a safe and effective non-invasive option for managing this type of tumor.
