Efficacy, safety and tolerability of GSK3858279, an anti-CCL17 monoclonal antibody and analgesic, in healthy volunteers and patients with knee osteoarthritis pain: a phase I, randomised, double-blind, placebo-controlled, proof-of-mechanism and proof-of-concept study
Bibliographic record
Abstract
OBJECTIVES: The objective of this study was to evaluate efficacy, safety and tolerability of the first-in-class, anti-CCL17 monoclonal antibody, GSK3858279, in treating knee osteoarthritis (OA) pain. METHODS: This was a phase I, randomised, placebo-controlled, two-part, proof-of-mechanism and proof-of-concept study. In part A, healthy participants were randomised 3:1 to receive GSK3858279 as either single intravenous (0.1-10 mg/kg) doses, a subcutaneous (3 mg/kg up to 240 mg maximum) dose, or placebo, to evaluate safety and tolerability. In part B, participants with knee OA pain were randomised 1:1 to receive weekly subcutaneous 240 mg GSK3858279, or placebo, for 8 weeks, to assess safety and change from baseline (CFB) in average and worst knee pain intensity. Exploratory endpoints included CFB in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain, function and stiffness scores. RESULTS: GSK3858279 demonstrated greater median CFB (95% credible interval (CrI)) in average and worst knee pain intensity versus placebo (average, -1.18 (-2.15, -0.20); worst, -1.09 (-2.29, 0.12)) at week 8. Median CFB (95% CrI) for GSK3858279 versus placebo in WOMAC pain and function scores were -1.41 (-2.35, -0.46) and -1.29 (-2.28, -0.29), respectively, at week 8. Overall, 72% (26/36; part A) and 88% (21/24; part B) of participants receiving GSK3858279 experienced adverse events (AEs); with nasopharyngitis being the most common in part A and injection site reactions in part B. No serious AEs or deaths were observed. CONCLUSION: GSK3858279 improved pain intensity and WOMAC pain and function scores in adults with knee OA pain and demonstrated favourable safety and tolerability in both healthy participants and adults with knee OA pain.

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.
