A post-marketing surveillance study of dabrafenib and trametinib combination in Japanese patients with unresectable advanced or recurrent BRAF-mutated NSCLC.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Combination therapy with dabrafenib and trametinib has been shown to improve response and survival outcomes in patients with BRAF V600E-mutated non-small cell lung cancer (NSCLC). However, safety and efficacy data in Japanese patients with unresectable NSCLC are limited in clinical trials. This post marketing surveillance study investigated the safety and effectiveness of dabrafenib and trametinib in Japan between March 2018 and August 2023. Most patients included in the safety analysis set (N = 76) had stage IV NSCLC (82.89%) and Eastern Cooperative Oncology Group performance status 0 or 1 (85.53%). Adverse events (AEs) occurred in 70 patients (92.11%); the most common AEs (≥ 5%) were pyrexia (46.05%), progression of NSCLC (38.16%), and rash (13.16%). Incidences of adverse drug reactions of safety specifications were pyrexia (46.05%), rhabdomyolysis (11.84%), and hepatic impairment and cardiac disorder (10.53% each). In the overall response rate (ORR) analysis set (n = 64), ORR was 67.19% (95% confidence interval [CI], 54.31-78.41%). Seventy-four patients were analyzed for progression-free survival (PFS); PFS rates (95% CI) at 182 days and 364 days were 71.07% (58.79-80.29%) and 49.64% (37.17-60.91%), respectively. Median PFS (95% CI) survival was 364 days (246.00 to not estimable). Real-world data observed in this surveillance study were similar to those reported previously.
