Phase 3, 56-week, randomised, double-blind, placebo-controlled study utilising patient-reported and radiographic outcomes evaluating the efficacy and safety of a lorecivivint injection in patients with moderate to severe knee osteoarthritis: OA-11 Study
Bibliographic record
Abstract
OBJECTIVES: To determine the efficacy, safety, and tolerability of intraarticular (IA) lorecivivint (LOR) in the treatment of knee osteoarthritis (OA). METHODS: Patients with American College of Rheumatology criteria-defined knee OA, Kellgren-Lawrence (KL) grades 2-3, and medial Joint Space Width (JSW) by radiograph between 1.5 and 4 mm in the target knee were enrolled in this phase 3, 56-week, multicentre, double-blind, placebo-controlled study. Patients were randomised (1:1) to receive a single IA injection of 0.07 mg LOR or vehicle placebo (PBO) on Day 1. The primary endpoint was the change from baseline in pain Numeric Rating Scale (NRS) at Week 12. Additional outcomes included the change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Function, WOMAC Pain, Patient Global Assessment, medial JSW, and safety. RESULTS: 513 patients were randomised. Baseline mean medial JSW was 2.61 (±0.7) mm. The mean change from baseline in weekly average of daily Pain NRS at Week 12 was LOR -2.24 (± 0.13) compared with PBO -2.49 (± 0.13); p=0.185, 95% confidence interval (CI) (-0.12, 0.62). No discernable treatment effects of LOR compared with PBO were revealed by the analysis of other endpoints. Neither treatment group showed meaningful medial JSW loss over 52 weeks. Incidences, severity, and relationship to study treatment of AEs were similar between LOR and PBO treatment groups. CONCLUSIOINS: In this study, LOR was well tolerated although it did not meet the primary endpoint of change from baseline in target knee Pain NRS at Week 12.

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.
