A Two-part Phase I Randomized, Double-blind, Placebo-controlled Study to Evaluate Safety, Tolerability, Pharmacokinetics and Target Engagement of Single Intravenous and Subcutaneous Doses of GSK3858279 in Healthy Participants and to Evaluate the Efficacy of Repeat Subcutaneous Doses in Participants With Osteoarthritis of the Knee

207804

This study is the first administration of GSK3858279 in humans and will be conducted in two parts: Part A will consist of a single ascending dose escalation design to evaluate safety, tolerability, PK, TE and immunogenicity of either a single intravenous (IV) or a single subcutaneous (SC) dose. Approximately 48 healthy participants will be enrolled in 6 cohorts and randomized to 3:1 ratio (GSK3858279 or placebo). Part B will evaluate safety, tolerability, efficacy (pain), PK, TE and immunogenicity after repeat SC dosing. Approximately 50 OA participants will be randomized in a parallel group design to receive either GSK3858279 or placebo in a 1:1 ratio.
