Osteoarthritis Clinical Trial

Official title: A 26-week, Multicenter, Double-blind, Randomized, Placebo-controlled Parallel Group Study to Evaluate the Efficacy and Safety of a Single Dose of 6 mL of Hylan G-F 20 (Synvisc-One®) in Chinese Patients With Symptomatic Osteoarthritis of the Knee

Status Completed

Clinical Trial Summary

Primary Objective:

-To evaluate the efficacy of a single 6-milliliter (mL) intra-articular (IA) injection of Hylan G-F 20 measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Numerical Rating Scale (NRS) 3.1 A1 score, in comparison to an IA placebo injection over 26 weeks, in Chinese participants with symptomatic Osteoarthritis (OA) of the knee.

Secondary Objectives:

• To evaluate the efficacy of a single 6-mL IA injection of Hylan G-F 20 measured by 7-day average score of WOMAC A1 pain sub-score in comparison to an IA placebo injection over 26 weeks.

• To evaluate the efficacy of a single 6-mL IA injection of Hylan G-F 20 measured by WOMAC A, patient global assessment (PTGA) and clinical observer global assessment (COGA) in comparison to an IA placebo injection over 26 weeks.

• To evaluate the response rate of a single 6-mL IA injection of Hylan G-F 20 in comparison to an IA placebo injection over 26 weeks. Response was defined as WOMAC A1 greater than or equal to (>=) 2-point improvement from baseline on NRS.

• To evaluate the safety of a single 6-mL IA injection of Hylan G-F 20, in comparison to an IA placebo injection over 26 weeks.

Clinical Trial Description

The duration of the study was 29 weeks at maximum. The screening and wash-out period lasted for up to 14 days, depending on the half-life of the medications followed by an 8-day baseline period including the treatment day. Overall, there were up to 21 days between signing informed consent (at screening visit) and the randomization (Day 1). Treatment was administered on Day 1, and follow-up period was 26 weeks. ;
