BMS-986012, an Anti–Fucosyl-GM1 Monoclonal Antibody as Monotherapy or in Combination With Nivolumab in Relapsed/Refractory SCLC: Results From a First-in-Human Phase 1/2 Study
Bibliographic record
Abstract
Introduction: Fucosyl-GM1 is a monosialoganglioside with limited expression in healthy tissues and high expression on SCLC cells. BMS-986012 is a nonfucosylated, first-in-class, fully human immunoglobulin G1 monoclonal antibody that binds to fucosyl-GM1. Methods: CA001-030 is a phase 1/2, first-in-human study of BMS-986012 as monotherapy or in combination with nivolumab for adults with relapsed or refractory SCLC. Safety is the primary end point. Additional end points include objective response rate, duration of response, progression-free survival, pharmacokinetics, and overall survival. Results: Patients (BMS-986012 monotherapy, n = 77; BMS-986012 + nivolumab, n = 29) were predominantly of male sex (58%), 63 years old (mean), current or past tobacco users (97%), and treated previously with first-line systemic therapy (99%). The most common treatment-related adverse event was pruritus (n = 95 [90%]). Grade 4 treatment-related adverse events were reported in 2% (n = 2) of patients. The objective response rate (95% confidence interval [CI]) was higher with BMS-986012 plus nivolumab (38% [20.7%-57.7%]) than with monotherapy (4% [0.8%-11.0%]). Median (95% CI) duration of response with BMS-986012 plus nivolumab was 26.4 (4.4-not reached) months. Progression-free survival (95% CI) at 24 weeks with monotherapy and BMS-986012 plus nivolumab was 12.2% (6.0%-20.7%) and 39.3% (21.7%-56.5%), respectively. The pharmacokinetics profile of monotherapy and BMS-986012 plus nivolumab suggested dose proportionality across the tested dose range. Median overall survival (95% CI) with monotherapy and BMS-986012 plus nivolumab was 5.4 (4.0-7.3) and 18.7 (8.2-37.3) months, respectively. Conclusions: BMS-986012 in combination with nivolumab represents a well-tolerated, potential new therapy for relapsed or refractory SCLC. BMS-986012 is currently being explored in combination with carboplatin, etoposide, and nivolumab as a first-line therapy in extensive-stage SCLC (NCT04702880).

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.
