Exploratory Analysis of Biomarkers and Treatment Outcomes from the COLUMBUS Study in BRAF V600E/K-Mutant Advanced or Metastatic Melanoma.
Trial report in Clinical cancer research : an official journal of the American Association for Cancer Research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTreatment with encorafenib ± binimetinib is associated with improved survival versus vemurafenib in patients with BRAF V600E/K-mutant advanced melanoma. We retrospectively analyzed genomic and transcriptomic data from the phase III COLUMBUS trial to identify molecular correlates of benefit with encorafenib ± binimetinib. EXPERIMENTAL
designIn COLUMBUS, patients with BRAF V600E/K-mutant locally advanced, unresectable, or metastatic melanoma (n = 921) were randomized to receive encorafenib plus binimetinib, encorafenib, or vemurafenib. We used whole-exome sequencing (n = 666), whole-transcriptome sequencing (RNA sequencing; n = 514), and assessment of circulating tumor DNA (ctDNA) at baseline (n = 336) and on treatment (cycle 2 day 1, n = 184) to evaluate biomarker associations with progression-free and overall survival.
resultsSurvival benefits with encorafenib plus binimetinib versus vemurafenib were greatest in patients with higher tumor mutational burden (TMB) and those with evidence of tumor immune infiltration (i.e., higher cytolytic score, PD-L1 expression, or IFNγ gene signature scores). Clustering of gene expression profiles identified three tumor subgroups, including an "immune" subgroup associated with improved survival. Detection of BRAF V600 alterations in baseline ctDNA was associated with shorter survival; clearance of BRAF V600 alterations at cycle 2 day 1 was associated with improved survival across arms.
conclusionsThe greatest benefits of encorafenib plus binimetinib were observed in patients with evidence of high TMB and/or tumor-immune infiltration, suggesting potential immune contributions to efficacy, which were not observed with vemurafenib. BRAF V600 detectability in ctDNA seems to have utility as a marker of prognosis and response in this population.
