Treatment Varies

Follow Up up to one year after treatment

Awards & highlights

No Placebo-Only Group

Summary

This trial is testing how well vemurafenib and cobimetinib work in treating patients with high-risk thyroid cancer that has a specific genetic mutation. These medications work by blocking abnormal proteins that signal

Who is the study for?

This trial is for patients with high-risk differentiated thyroid carcinoma that has a specific BRAFV600E gene mutation. It's aimed at those preparing for radioactive iodine therapy.

What is being tested?

The effectiveness of vemurafenib and cobimetinib, both kinase inhibitors, is being tested to see if they can better prepare patients with the BRAFV600E mutation for radioactive iodine treatment by slowing cancer growth.

What are the potential side effects?

Possible side effects include fatigue, skin rash, joint pain, nausea, liver problems, heart issues, and vision changes due to the action of kinase inhibitors on abnormal proteins in cancer cells.

1Treatment groups

Experimental Treatment

Group I: Treatment (vemurafenib and cobimetinib)Experimental Treatment11 Interventions

Patients receive vemurafenib PO BID for 6 weeks and cobimetinib PO QD for 3 weeks, followed by 1 week off, and then continuing for 2 weeks. Patients then receive iodine 131 PO followed by 3 additional days of vemurafenib PO BID and cobimetinib PO QD. Patients receive thyrogen IM daily for 2 days followed by I-123 diagnostic scan during screening and on study. Patients also undergo MRI during screening, PET scan or CT scan and blood sample collection throughout the study and ultrasound imaging and I-131 whole body scan during follow up.
