Final results of the large-scale multinational trial PROFILE 1005: efficacy and safety of crizotinib in previously treated patients with advanced/metastatic ALK-positive non-small-cell lung cancer
Bibliographic record
Abstract
PURPOSE: Crizotinib is a potent, orally administered tyrosine kinase inhibitor approved for the treatment of anaplastic lymphoma kinase (ALK)-positive advanced non-small-cell lung cancer (NSCLC). We report final results from PROFILE 1005, the largest clinical trial to date for an ALK inhibitor in ALK-positive NSCLC. PATIENTS AND METHODS: PROFILE 1005 (NCT00932451) was a multicenter, single-arm phase 2 trial of the efficacy, safety and tolerability of crizotinib (250 mg twice daily; 3 week continuous treatment cycles) in patients with ALK-positive NSCLC after failure of ≥1 lines of systemic treatment for locally advanced/metastatic disease. Patients' tumour ALK status was initially determined by a central laboratory until a protocol amendment permitted enrolment of patients based on locally determined ALK status. Co-primary endpoints were objective response rate (ORR), evaluated using Response Evaluation Criteria in Solid Tumours V.1.1 and adverse events (AEs). Cancer-specific patient-reported outcomes (PROs) were also assessed using the European Organisation for the Research and Treatment of Cancer QLQ-C30 and its lung cancer module QLQ-LC13. RESULTS: status was determined centrally (± locally) or locally only, respectively. At baseline, a majority of patients were <65 years (84%), 66% were never smokers and 46% were Asian. Derived investigator-assessed ORR was 54% (95% CI 51 to 57) and 41% (95% CI 33 to 49) in the central-testing and local-testing subgroups, respectively. The most common treatment-related AEs in the overall population (any grade) were vision disorder (58%), nausea (51%), diarrhoea (47%) and vomiting (47%). PRO scores demonstrated clinically meaningful improvement in lung cancer symptoms and global quality of life. CONCLUSION: The efficacy, safety and PRO profiles of crizotinib in this cohort of 1066 patients with ALK-positive NSCLC are consistent with previous reports. TRIAL REGISTRATION NUMBER: Phase 2 trial (NCT00932451); Results.

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.
