Combination of encorafenib and binimetinib in the treatment of patients with <i>BRAF</i>-mutated advanced melanoma. Case report

Abstract

Background. The need to use BRAF and MEK inhibitors in the treatment of patients with metastatic and/or unresectable BRAF + melanoma in certain clinical situations is beyond doubt nowadays. The medical community need more information about the new combination of targeted therapy approved in Russia, further details on the expected efficacy and tolerability, potential differences from the existing combinations.
 Aim. To present of the study results and demonstration of our experience with the new generation of targeted therapy encorafenib and binimetinib combination in the treatment of patients with metastatic and/or inoperable BRAF+ melanoma.
 Materials and methods. We present the clinical case of BRAF+ advanced melanoma patient with multiple metastases in the liver, spleen, mediastinal and abdominal lymph nodes, stomach and bones who is being treated with encorafenib and binimetinib since 2015 with the treatment efficacy and tolerability described in details, as well as the published data on the efficacy and tolerability of this combination from the pivotal phase III study COLUMBUS.
 Results. High immediate and long-term efficacy, satisfactory tolerability of encorafenib and binimetinib combination are presented. Updated data on progression-free and overall survival in the COLUMBUS study confirmed the long-term efficacy of COMBO450 therapy in patients with advanced melanoma with BRAF V600 mutation.
 Conclusion. New generation of BRAFi and MEKi combination expands options of systemic therapy for patients with metastatic and/or inoperable BRAF+ melanoma.
