Longitudinal Genomic Analysis to Fine-tune Targeted Therapy: Results of the Phase II LOGIC 2 Trial in Patients with <i>BRAF</i> V600-Mutant Metastatic Melanoma
Bibliographic record
Abstract
PURPOSE: LOGIC 2 (NCT02159066), a multicenter, open-label, two-part, phase II study, assessed encorafenib plus binimetinib combined with a third targeted agent after tumor progression on encorafenib plus binimetinib in patients with locally advanced, unresectable or metastatic BRAFV600-mutant melanoma. PATIENTS AND METHODS: Adults with locally advanced, unresectable or metastatic BRAFV600-mutant melanoma who were BRAF inhibitor/MEK inhibitor (BRAFi/MEKi) treatment-naïve or pretreated received encorafenib plus binimetinib (part I/run-in). Based on the genomic testing at disease progression following encorafenib plus binimetinib, patients were assigned to one of four treatment arms to receive encorafenib plus binimetinib with an appropriate molecularly targeted agent (ribociclib, infigratinib, capmatinib, or buparlisib; part II). The primary endpoint was best overall response; safety, biomarkers, pharmacokinetics, and other efficacy endpoints were also assessed. RESULTS: In part I/run-in, 75 BRAFi/MEKi-naïve patients and 83 BRAFi/MEKi-pretreated patients were treated; in part II, 58 patients were treated (ribociclib, n = 38; infigratinib, n = 1; capmatinib, n = 13; buparlisib, n = 6). The overall confirmed response rate was 73.3% [95% confidence interval (CI), 61.9-82.9] in BRAFi/MEKi-naïve patients, 25.3% (95% CI, 16.4-36.0) in pretreated patients, 2.6% (95% CI, 0.1-13.8) in the ribociclib arm, and 0% in the other three arms. Adverse events were manageable and consistent with the known safety profile of each drug. CONCLUSIONS: LOGIC 2 supports the use of encorafenib plus binimetinib for treatment-naïve and previously treated, locally advanced, unresectable or metastatic BRAFV600-mutant melanoma. However, adding a third targeted agent following disease progression did not show meaningful efficacy; further research is needed to identify other therapeutic targets to circumvent resistance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
