TLC599 in patients with osteoarthritis of the knee: a phase IIa, randomized, placebo-controlled, dose-finding study
Bibliographic record
Abstract
BACKGROUND: Corticosteroid injection for knee osteoarthritis is limited by its modest duration of treatment effect. The liposome formulation of dexamethasone sodium phosphate (TLC599) was developed for the sustained relief of osteoarthritis pain. This clinical study was conducted to evaluate the efficacy and safety of TLC599 at two dose levels in patients with knee osteoarthritis. METHODS: A randomized, double-blinded, placebo-controlled study was conducted in 75 patients with osteoarthritis of the knee from 13 study centers. Patients were randomized and administered a single intra-articular injection of TLC599 or placebo and assessed for efficacy and safety for 24 weeks. Patient-reported outcomes included the Western Ontario and McMaster Universities Arthritis (WOMAC) Index for pain and function and visual analog scale for pain. RESULTS: TLC599 at 12 mg demonstrated significantly greater reduction in WOMAC pain through 12 weeks (least squares (LS) mean difference = - 0.37, p = 0.0027) and through 24 weeks (LS mean difference = - 0.35, p = 0.0037) when compared to placebo. TLC599 12 mg also exhibited significantly greater improvement in function when compared to placebo at 24 weeks (LS mean difference = - 0.26, p = 0.0457). TLC599 18 mg did not significantly improve pain or function in comparison with placebo. The use of acetaminophen during the study was less in both TLC599 groups in comparison with placebo. No major or unexpected safety issues were reported. CONCLUSIONS: In participants with symptomatic knee osteoarthritis, TLC599 is a well-tolerated treatment that reduces pain and improves function for up to 24 weeks, a longer duration than that reported for existing IA treatments.

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.
