A Study of Hyaluronate Injectable Viscosupplement for Treatment of Osteoarthritis of the Knee

A Double-Blind, Randomized, Study of the Effectiveness and Safety of Hyaluronate Injectable Viscosupplement for Treatment of Osteoarthritis of the Knee

The study is a prospective, multi-center, randomized, three-arm, parallel group, clinical study to evaluate the superiority of 3 weekly intra-articular (IA) doses of 2 mL of Investigational hyaluronate as compared to placebo injected into the target knee for the treatment of pain in subjects with Osteoarthritis (OA).The safety and effectiveness of the investigational product will also be compared with Euflexxa.

Study Overview

• Status: Completed
• Conditions: Osteoarthritis
• Intervention / Treatment: Device: Hyaluronate Injectable Viscosupplement; Device: Euflexxa IA injection; Device: Placebo

Detailed Description

The primary objective is to evaluate the safety and effectiveness of 3 weekly IA doses of 2 mL of hyaluronate viscosupplement as compared to placebo injected into the target knee for the treatment of pain in subjects with OA As secondary objectives, the study will evaluate the safety and effectiveness of 3 weekly IA doses of 2 mL of Viscosupplement as compared to Euflexxa injected into the target knee for the treatment of pain in subjects with OA. In addition, to assess the effect of Viscosupplement on pain, stiffness, and physical function of the target knee, as well as functional health and general well-being

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in the WOMAC Pain Score in the Target Knee at Week 26 [Western Ontario and McMaster Universities Arthritis Index (WOMAC®)]	The primary effectiveness endpoint was the change from Baseline in the Western Ontario and McMaster Universities Arthritis Index (WOMAC®) pain score in the target knee at Week 26.The validated WOMAC was used to assess pain, stiffness, and physical function of the target knee.The range of pain score was 0 to 500 mm with higher scores for worse pain.	Baseline and 26 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Pain Over Time From Baseline to Week 1, Week 6, Week 12 and Week 26	The change from Baseline in the WOMAC pain score over time (baseline to Week 1, Week 6, Week 12 and Week 26) using Western Ontario and McMaster Universities Arthritis Index (WOMAC®)].The validated WOMAC was used to assess pain, stiffness, and physical function of the target knee.The range of pain score was 0 to 500 mm with higher scores for worse pain.	26 weeks
Change in Stiffness of the Knee After 26 Weeks as Measured by the WOMAC Pain Score in the Target Knee at Week 26 [Western Ontario and McMaster Universities Arthritis Index (WOMAC®)]	The change from baseline in the stiffness in the target knee at Week 26. The validated WOMAC was used to assess pain, stiffness, and physical function of the target knee.The range of stiffness score was 0 to 100 mm with higher scores for worse stiffness.	26 weeks
