Provisional Patent Application Filed

Description:

The drug Vemurafenib is one of the few treatment options for late-stage melanoma currently available. However, upon either single or chronic treatment with Vemurafenib, the cancer cells develop mechanisms of resistance to the drug.  Other drugs available in the market such as Mek1/2 inhibitors and BRAF inhibitors fail to overcome Vemurafenib resistance.

This invention has identified the mechanism that creates the resistance to Vemurafenib for the treatment of melanoma, and the class of drugs that are used in combination with Vemurafenib will prevent resistance.  The research has identified individual compounds within the class that have proved most effective for treatment of melanoma in combination with Vemurafenib, improving prognosis for patients and reducing the chance of relapse.

Reference Number: D-1172

Market Applications:
