Brief Summary:
The purpose of this study is to determine whether intra-articular injection of Monovisc® hyaluronic acid provides symptomatic relief of osteoarthritis of the knee.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Osteoarthritis | Device: Monovisc® Other: Saline | Not Applicable |
This randomized, double-blind, placebo controlled prospective study will assess the safety and effectiveness of a single intra-articular injection of Monovisc® in providing symptomatic relief of pain caused by idiopathic osteoarthritis (OA) of the knee as compared to a placebo comparator injection of sterile saline.

Primary Outcome Measures :
- Proportion Subjects Achieving Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score (ITT) >=40% and 15 mm From Baseline Through 12 Weeks [ Time Frame: 12 Weeks ]The primary endpoint measures the proportion of subjects (Monovisc vs. saline) who achieved >= a 40% improvement (reduction) in the WOMAC Pain Score and show at least 15 mm improvement (reduction) in the WOMAC Pain Score from baseline through 12 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score is a validated scale from 0 to 100 mm, where a higher score is equal to a higher pain level. The primary endpoint uses the ITT population that has data available for both baseline and 12 week time points.
Secondary Outcome Measures :
- Evaluator Global Assessment Change From Baseline Through Week 12 (ITT) [ Time Frame: 12 Weeks ]Comparison of the change of the Evaluator Global Assessment from baseline through Week 12 between Monovisc and saline arms (ITT Population). The Evaluator Global Assessment is done by the Blinded Evaluator, and answers the question "Considering all the ways the osteoarthritis in the patient's index knee affect him/her, what is your assessment of how much the patient's knee is bothering him/her today?" The Evaluator Global Assessment is scored on a 0 to 100 mm Visual Analog Scale (VAS Scale), where a higher number means the patient is bothered to a higher degree. A negative number for the change from baseline indicates a reduction (improvement) in the assessment. The endpoint uses the ITT population that has data available for both baseline and 12 week time points.
- Patient Global Assessment Change From Baseline Through Week 12 (ITT) [ Time Frame: 12 Weeks ]Comparison of the change of the Patient Global Assessment from baseline through Week 12 between Monovisc and saline arms (ITT Population). The Patient Global Assessment is done by the patient, and answers the question "Considering all the ways the osteoarthritis in your study knee affects you, what is your assessment of how much your study knee is bothering you today?" The Patient Global Assessment is scored on a 0 to 100 mm Visual Analog Scale (VAS Scale), where a higher number means the patient is bothered to a higher degree. A negative number for the change from baseline indicates a reduction (improvement) in the assessment. The endpoint uses the ITT population that has data available for both baseline and 12 week time points.
- Range of Motion Change From Baseline Through Week 12 (ITT) [ Time Frame: 12 Weeks ]Comparison of the change of Range of Motion from baseline through Week 12 between Monovisc and saline arms (ITT Population). Range of motion is defined as the difference between flexion and extension in degrees where full extension range is 180 degrees. The endpoint uses the ITT population that has data available for both baseline and 12 week time points.
- WOMAC Physical Function Score Change From Baseline Through Week 12 (ITT) [ Time Frame: 12 Weeks ]This endpoint compares the change of the WOMAC Physical Function Score from baseline through Week 12 between Monovisc and saline arms (ITT Population). The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Score is a validated scale from 0 to 100 mm, where a higher score is equal to a higher degree of functional limitation. A negative number for the change from baseline indicates improvement in physical function. The ITT population includes subjects with data at baseline and 12 Week time points.
