1.1 Encorafenib with binimetinib is recommended, within its marketing authorisation, as an option for treating unresectable or metastatic BRAF V600 mutation-positive melanoma in adults. It is recommended only if the company provides encorafenib and binimetinib according to the commercial arrangements.
Why the committee made these recommendations
Current treatments for unresectable or metastatic BRAF V600 mutation-positive melanoma include targeted therapy, usually using a combination of a BRAF and MEK inhibitor (dabrafenib with trametinib) or sometimes monotherapy with a BRAF inhibitor (vemurafenib or dabrafenib).
Clinical trial evidence shows that, compared with vemurafenib, encorafenib with binimetinib extends the time until melanoma progresses and also how long people live. There are no trials directly comparing it against dabrafenib with trametinib. But compared indirectly, encorafenib with binimetinib appears to be as effective as dabrafenib with trametinib.
When the commercial arrangements for encorafenib, binimetinib, dabrafenib and trametinib are taken into account, encorafenib with binimetinib is considered to be a cost-effective use of NHS resources. It is therefore recommended.
