|Title||Dabrafenib in patients with BRAF(V600E)-positive advanced non-small-cell lung cancer: a single-arm, multicentre, open-label, phase 2 trial.|
|Journal||The Lancet. Oncology|
|Abstract Text||Activating BRAF(V600E) (Val600Glu) mutations are found in about 1-2% of lung adenocarcinomas, which might provide an opportunity for targeted treatment in these patients. Dabrafenib is an oral selective inhibitor of BRAF kinase. We did a trial to assess the clinical activity of dabrafenib in patients with advanced non-small-cell lung cancer (NSCLC) positive for the BRAF(V600E) mutation.In this phase 2, multicentre, non-randomised, open-label study, we enrolled previously treated and untreated patients with stage IV metastatic BRAF(V600E)-positive NSCLC. Patients received oral dabrafenib 150 mg twice daily. The primary endpoint was investigator-assessed overall response, which was assessed in patients who had received at least one dose of dabrafenib; safety was also assessed in this population. The study is ongoing but not enrolling patients in this cohort. This trial is registered with ClinicalTrials.gov, number NCT01336634.Between Aug 3, 2011, and Feb 25, 2014, 84 patients were enrolled, six of whom had not previously received systemic treatment for NSCLC. 26 of the 78 previously treated patients achieved an investigator-assessed overall response (33% [95% CI 23-45]). Four of the six previously untreated patients had an objective response. One patient died from an intracranial haemorrhage that was judged by the investigator to be due to the study drug. Serious adverse events were reported in 35 (42%) of 84 patients. The most frequent grade 3 or worse adverse events were cutaneous squamous-cell carcinoma in ten (12%), asthenia in four (5%), and basal-cell carcinoma in four (5%).Dabrafenib showed clinical activity in BRAF(V600E)-positive NSCLC. Our findings suggest that dabrafenib could represent a treatment option for a population of patients with limited therapeutic options.GlaxoSmithKline.|

|BRAF V600E||lung non-small cell carcinoma||sensitive||Dabrafenib + Trametinib||FDA approved - On Companion Diagnostic||Actionable||In a Phase II trial that supported FDA approval, treatment with the combination of Mekinist (trametinib) and Tafinlar (dabrafenib) in patients with non-small cell lung cancer harboring BRAF V600E resulted in an overall response rate of 66.7% (38/57) in previously treated patients and 64% (23/36) in untreated patients, versus 33% (26/78) treated with Tafinlar (dabrafenib) alone (PMID: 27080216, PMID: 27283860, PMID: 28919011; NCT01336634).||27283860 detail... 27080216 detail... detail... 28919011|
|BRAF V600E||lung non-small cell carcinoma||sensitive||Dabrafenib||Phase II||Actionable||In a Phase II trial, 33% (26/78) of previously treated non-small cell lung carcinoma patients harboring BRAF V600E demonstrated an overall response, which included all partial responses, when treated with Tafinlar (dabrafenib) while 67% (4/6) receiving Tafinlar (dabrafenib) as a first-line treatment achieved partial responses (PMID: 27080216; NCT01336634).||27080216|
