Randomized Phase II Trial of a Toll-Like Receptor 9 Agonist Oligodeoxynucleotide, PF-3512676, in Combination With First-Line Taxane Plus Platinum Chemotherapy for Advanced-Stage Non–Small-Cell Lung Cancer
Bibliographic record
Abstract
PURPOSE: This study assessed the efficacy of the combination of standard taxane plus platinum chemotherapy with the synthetic Toll-like receptor 9-activating oligodeoxynucleotide PF-3512676 in patients with non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy-naive patients with stage IIIB to IV NSCLC were randomly assigned (one to two ratio) to receive four to six cycles of taxane/platinum chemotherapy alone or with 0.2 mg/kg of subcutaneous PF-3512676 on days 8 and 15 of each 3-week cycle. The primary end point was objective response rate (ORR). RESULTS: Baseline demographics were similar between treatment arms, although significantly more patients in the PF-3512676 arm had stage IV disease (85% compared with 62% in the chemotherapy-alone arm). The modified intent-to-treat analysis (n = 111) demonstrated a 38% ORR (confirmed and unconfirmed) in the PF-3512676 arm (n = 74) and 19% in the chemotherapy-alone arm (n = 37) by investigator evaluation. Blinded, independent radiologic review for 90 patients showed a similar trend in confirmed response rate (19% and 11%, respectively). Median survival was 12.3 months in the PF-3512676 arm and 6.8 months in the chemotherapy-alone arm, and 1-year survival was 50% and 33%, respectively. Mild to moderate local injection site reactions and flu-like symptoms were the most common PF-3512676-related adverse events, but grade 3/4 neutropenia, thrombocytopenia, and anemia were all reported more commonly for patients in the PF-3512676 arm. CONCLUSION: The addition of PF-3512676 to taxane plus platinum chemotherapy for first-line treatment of NSCLC improves objective response and may improve survival. Confirmatory phase III trials are ongoing.

How this classification was reachedexpand
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.
