Telisotuzumab vedotin (Teliso-V) monotherapy in patients (pts) with previously treated c-Met–overexpressing (OE) advanced non-small cell lung cancer (NSCLC).
Bibliographic record
Abstract
9016 Background: Teliso-V is an antibody-drug conjugate composed of a c-Met antibody (ABT-700) and a microtubule inhibitor (monomethyl auristatin E). The phase 2 M14-239 trial (LUMINOSITY, NCT03539536) aims to identify the c-Met OE NSCLC populations best suited to Teliso-V (Stage 1) and expand selected groups for further evaluation of efficacy (Stage 2). In Stage 1, pts were enrolled into cohorts defined by histopathology (non-squamous [NSQ] or squamous [SQ]) and EGFR mutation status (mutant or wild type [WT]); NSQ cohorts were further divided in groups on the basis of c-Met expression (high or intermediate). Updated data from the fourth interim analysis (IA4) are presented. Methods: Pts had locally advanced/metastatic NSCLC, ≤2 prior lines of systemic therapy, ≤1 line of chemotherapy, and tumors that were c-Met OE by central immunohistochemistry (IHC; Ventana; Tucson, AZ). c-Met OE was defined for the NSQ cohort as ≥25% 3+ by IHC (high, ≥50% 3+; intermediate, 25 to <50% 3+) and for the SQ cohort as ≥75% 1+ by IHC. The planned enrollment was up to approximately 150 pts in Stage 1 and 160 pts in Stage 2. Teliso-V was dosed at 1.9 mg/kg IV Q2W. The primary endpoint is objective response rate (ORR) by independent central review. Secondary endpoints include duration of response (DOR). Results: As of data cutoff (27 May 2021), 136 pts were treated with Teliso-V; 122 were evaluable for ORR. ORR was 36.5% in the NSQ EGFR WT cohort (52.2% in c-Met high group and 24.1% in c-Met intermediate group), but was modest in the NSQ EGFR mutant and SQ cohorts. Efficacy data in groups/cohorts are in the Table. The most common any-grade adverse events (AEs) were peripheral sensory neuropathy (25.0%), nausea (22.1%), and hypoalbuminemia (20.6%). Grade 5 AEs considered possibly related to Teliso-V occurred in 2 pts (sudden death and pneumonitis in 1 pt each in the SQ cohort). Conclusions: Teliso-V demonstrated a promising ORR in pts with previously treated c-Met OE NSQ EGFR WT NSCLC; this cohort is currently expanding in Stage 2. ORR was modest in the cohorts of pts with c-Met OE NSQ EGFR mutant NSCLC and with c-Met OE SQ NSCLC; both cohorts have now met the protocol-specified stopping criteria and are no longer enrolling. The safety profile observed was consistent with IA3. Clinical trial information: NCT03539536. [Table: see text]

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
