Gel-200 Versus Placebo in Osteoarthritis of the Knee
October 3, 2011 updated by: Seikagaku Corporation
A Multi-Center, Randomized, Double-Blind, Controlled, Parallel-Group Study of a Single Intra-Articular Injection of Gel-200 With a Single Intra-Articular Injection of Phosphate Buffered Saline (PBS) in Osteoarthritis of the Knee.
The purpose of this study is to determine if a single intra-articular injection of Gel-200 is superior to a single injection of Phosphate Buffered Saline (PBS) in subjects with symptomatic osteoarthritis of the knee.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Visual Analog Scale (VAS) Pain Subscore
Time Frame: Baseline and Week 13
|
Observed WOMAC pain subscore on VAS of 100 mm; 0 mm meaning no pain; 100 mm meaning extreme pain.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in WOMAC VAS Stiffness Subscore
Time Frame: Baseline and Week 13
|
Observed WOMAC stiffness subscore on Visual Analog Scale (VAS) of 100 mm; 0 mm meaning no stiffness; 100 mm meaning extreme stiffness.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.
|
Baseline and Week 13
|
Change From Baseline in WOMAC VAS Physical Function Subscore
Time Frame: Baseline and Week 13
|
Observed WOMAC physical function subscore on Visual Analog Scale (VAS) of 100 mm; 0 mm meaning no difficulty; 100 mm meaning extreme difficulty.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.
|
Baseline and Week 13
|
Change From Baseline in WOMAC VAS Total Score
Time Frame: Baseline and Week 13
|
Mean of all WOMAC pain, stiffness and physical function subscores on Visual Analog Scale (VAS) of 100 mm; 0 mm meaning no pain, stiffness and difficulty; 100 mm meaning extreme pain, stiffness and difficulty.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.
|
Baseline and Week 13
|
Outcome Measures in Rheumatology Arthritis Clinical Trials (OMERACT)- and the Osteoarthritis Research Society International (OARSI) Response
Time Frame: Weeks 6 to 13
|
Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) strict responses defined by changes from baseline in WOMAC pain or physical function subscore ≥50% with absolute changes ≥20 mm (termed strict responders), or ≥20% with absolute changes ≥10mm in 2 of 3 measures of WOMAC pain or physical function subscore or subject global evaluations (termed responders).
|
Weeks 6 to 13
|
Change From Baseline in Short Form - 36 (SF-36)
Time Frame: Baseline and Week 13
|
Scored on physical component scale from 0 (negative health) to 100 (positive health).
Calculated norm based with a mean of 50 and a standard deviation of 10.
|
Baseline and Week 13
|
Change From Baseline in Subject Global Evaluations
Time Frame: Baseline and Week 13
|
Observed subject evaluations on Visual Analog Scale (VAS) of 100 mm; 0 mm meaning excellent feeling in knee joint; 100 mm meaning poor feeling in knee joint.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.
|
Baseline and Week 13
|
Change From Baseline in Physician Global Evaluations
Time Frame: Baseline and Week 13
|
Observed physician global evaluations on Visual Analog Scale (VAS) of 100 mm; 0 mm meaning excellent feeling in knee joint; 100 mm meaning poor feeling in knee joint.
Change in score from baseline to week 13 was calculated as baseline minus week 13.
Primary endpoint was the model estimated difference between Gel-200 and PBS placebo.
|
Baseline and Week 13
