Официальное название

Multicenter, Randomized, Double-blind, Active Control, Parallel, Non-inferior, Phase 4 Clinical Trial to Assess Efficacy and Safety of Laybon Tab. in Patients With Knee Osteoarthritis

Обзор

This Phase 4, multicenter, randomized, double-blind, active-controlled, parallel study aims to evaluate the non-inferiority of Laybon Tab. compared to Layla Tab. (PMG Pharm Co., Ltd.) in patients with knee osteoarthritis. Participants will receive either Laybon Tab. or Layla Tab. for 8 weeks. The primary outcome is the change in knee pain during activity, assessed by a 100 mm pain VAS over the previous 24 hours.

Подробное описание

This phase 4 clinical trial will assess the efficacy and safety of Laybon Tab. compared to Layla Tab. in adults with knee osteoarthritis. Participants will be randomized in a double-blind, parallel, active-controlled design to receive either Laybon Tab. or Layla Tab. for 8 weeks. The primary endpoint is the change in activity-related knee pain over the past 24 hours, measured by a 100 mm visual analogue scale (VAS). Secondary endpoints include additional efficacy and safety evaluations. The study aims to demonstrate the non-inferiority of Laybon Tab. to Layla Tab. All participants will be monitored for efficacy, safety, and medication compliance, and standard eligibility criteria will be applied.
