What Is Known And ObjectiveMelanoma causes the majority of skin cancer-related deaths. The outcome of melanoma depends on its stage at diagnosis. Currently, for patients with advanced melanoma, two MEK inhibitors (trametinib and cobimetinib) have been authorized by the European Medicines Agency. The main objective of this study was to compare the relative efficacy of trametinib-dabrafenib and cobimetinib-vemurafenib in patients with advanced melanoma through adjusted indirect treatment comparisons (ITCs).MethodsA search was made up to the 3rd of November 2015. Databases consulted were MEDLINE, the Cochrane Library and the Centre for Reviews and Dissemination. Randomized controlled trials (RCTs) which compared the efficacy of trametinib-dabrafenib or cobimetinib-vemurafenib versus a common treatment comparator, in which outcomes of overall survival, progression-free survival (PFS) and overall response rate (ORR) were considered. ITCs were carried out using the method proposed by Bucher et al.Results And DiscussionTwo RCTs were included (one for each drugs combination). The results of the adjusted ITCs showed that there were no statistically significant differences between the two combinations in terms of PFS and ORR.What Is New And ConclusionThe ITCs indicate no difference in efficacy between both treatments. However, there should be an independent, head-to-head trial of both combinations to confirm the results.© 2016 John Wiley & Sons Ltd.
