Efficacy and safety of low-dose SoluMatrix meloxicam in the treatment of osteoarthritis pain: a 12-week, phase 3 study
Bibliographic record
Abstract
OBJECTIVE: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as meloxicam are commonly used to treat osteoarthritis (OA) but are associated with potentially serious dose-related adverse events (AEs). SoluMatrix meloxicam has been developed with the goal of enabling effective treatment at low doses. This phase 3 study evaluated the efficacy and safety of low-dose SoluMatrix meloxicam capsules 5 mg and 10 mg administered once daily for 12 weeks in patients with OA-related pain. RESEARCH DESIGN AND METHODS: This randomized, double-blind study enrolled patients ≥40 years of age with confirmed hip or knee OA (Kellgren-Lawrence grade II-III) who were chronic users of NSAIDs and/or acetaminophen for OA pain and had Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale mean scores ≥40 mm. Eligible patients experienced an OA pain flare (defined as a ≥15 mm increase in the WOMAC pain subscale score) following discontinuation of NSAIDs/acetaminophen. Patients were randomized to receive once-daily SoluMatrix meloxicam 5 mg or 10 mg, or placebo for 12 weeks. ClinicalTrials.gov identifier: NCT01787188. MAIN OUTCOME MEASURES: The primary outcome measure was the mean change from baseline in WOMAC pain subscale score at week 12. RESULTS: Low-dose SoluMatrix meloxicam 5 mg (-36.52 [2.49]; P = 0.0005) and 10 mg (-34.41 [2.68]; P = 0.0059) once-daily treatment significantly reduced the mean (standard error) WOMAC pain subscale score from baseline at week 12 compared with placebo (-25.68 [2.64]). Patients treated with SoluMatrix meloxicam 5 mg or 10 mg reported significantly greater improvements in total WOMAC score and in WOMAC stiffness and function subscale scores at 12 weeks compared with placebo. The most common AEs in the combined low-dose SoluMatrix meloxicam group were headache, diarrhea, nausea, osteoarthritis, and urinary tract infection. CONCLUSIONS: Low-dose SoluMatrix meloxicam may have a potential role as a new therapeutic option for the management of OA-related pain.

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.
