Osteoarthritis

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

Ann Rheum DisPublished Randomised controlled trial

Authors' 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.
