Abstract
1036 Background: Met, a receptor tyrosine kinase, is preferentially expressed in basal-like compared to luminal breast cancer. In murine models, overexpression of the oncogenic Met receptor transgene induces tumors with human basal gene expression characteristics supporting Met inhibition as a treatment strategy for triple negative (TN) breast cancer. Foretinib is an oral multi-kinase inhibitor of Met, RON, AXL, TIE-2 and VEGF receptors with anti-tumor activity in advanced HCC and papillary renal cell cancer. Methods: Patients (pts) with TN breast cancer and 0-1 prior regimens for metastatic disease received daily foretinib 60 mg po in a 2-stage single arm trial. Primary endpoints were objective response and early progression rates per RECIST 1.1. Tumor samples were centrally reviewed to confirm ER/PR/HER2 status and for correlative studies including Met, PTEN and EGFR expression. Stage 1 accrual required 23 response-evaluable Met unselected patients with accrual continuing if >/= 1 response or < 17 early progressions (PD <= 8 weeks on study) were observed. Results: Accrual is 29 pts to date; 24 are eligible, 22 evaluable for toxicity and 15 for response. Median age is 56 y (43-81), ECOG PS 0-1 in 23/24. Grade 3 laboratory adverse events were: lymphopenia (9%), elevations in ALT (5%), GGT (5%) and INR (5%). Treatment-related non-hematologic toxicities included (all/grade 3-4) fatigue (64%/5%), nausea (55%/5%), diarrhea (41%/5%), hypertension (32%/14%), vomiting (27%/0%), anorexia (23%/5%) and rash (14%/0%). Three SAEs possibly related to foretinib included; asymptomatic pulmonary embolism, reversible CHF and pleural effusion with QTc prolongation. One PR (7%), 8 early PD (53%) and 6 SD (40%) have been observed to date with median SD duration of 5.4 months (range 2.7-5.5). Preliminary correlative results (IHC): 5/8 (62.5%) evaluable Met positive cases had SD and 4/5 (80%) Met negative cases had PD as best response. Met IHC was negative in the pt with PR. Conclusions: Foretinib shows preliminary evidence of activity and tolerability in metastatic, TN breast cancer. Stage 2 of accrual will include 15 pts with pre-treatment biopsies of metastases and circulating tumor cell collection.

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 it
