Clinical Trial Summary

This is a multi-center, randomized, double-blind, parallel group, placebo controlled trial to compare the safety and effectiveness of a single injection of Cingal® to a single injection of Triamcinolone Hexacetonide (TH) to achieve pain relief and other symptoms of osteoarthritis of the knee.

Description:

To determine the contribution of Triamcinolone Hexacetonide (TH) when combined with sodium hyaluronate for pain relief, both in terms of magnitude and duration, when used as single injection, as compared to a single injection of TH alone in subjects diagnosed with osteoarthritis of the knee. A saline placebo is included within the trial to set the expectation of a return to Baseline pain for the subjects.

Secondary	The Outcomes Measures for Rheumatic Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) Responder Index	The post-treatment responder rate is determined through a calculation defined by the Outcomes Measures for Rheumatic Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) Responder Index. The OMERACT-OARSI Responder Index reports the percentage of subjects that met the criteria to be a good responder to treatment. The criteria for response are (1) improvement in pain or physical function >50% and an absolute change >20 mm; or (2) improvement of >20% with an absolute change >10 mm in at least of the following three categories: pain, physical function, and patient's global assessment.; A higher percentage of subjects responding indicates a better outcome.; OMERACT-OARSI responder rates were compared between the Cingal, TH and Placebo arms.	26 Weeks
Secondary	Change From Baseline in Knee Pain as Measured by Visual Analog Scale (VAS) Pain Score	Change in knee pain was obtained from participant responses using a 100 mm Visual Analog Scale (VAS) Pain Score at each time point.

A larger negative value indicates a higher level of improvement, and a better outcome.	26 Weeks
Secondary	Change From Baseline in Knee Pain as Measured by Numerical Rating Scale (NRS) Pain Score	Change in knee pain was obtained from participant responses using a Numerical Rating Scale (NRS) Pain Score. This NRS Pain Score ranged from 0 = No Pain to 10 = Highest Pain Level. A negative value for the change in Pain Score indicates less pain post-treatment. A larger negative value indicates a higher level of improvement, and a better outcome.	26 Weeks
Secondary	Change From Baseline in the Western Ontario and McMaster Universities Arthritis Index (WOMAC) Function Score	The change from Baseline in knee function post-treatment as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Function Score comparing the Cingal, TH, and Placebo arms. WOMAC Function Score records participant responses regarding the difficulty they have performing daily activities. The WOMAC Function Score is a validated 100 mm visual analog scale (VAS) from 0 mm = No Difficulty to 100 mm = Extreme Difficulty. A negative value for the change from Baseline indicates improvement in WOMAC Function Score. A larger negative value indicates improvement in performing daily activities, and a better outcome.	26 Weeks

WOMAC Stiffness Score records participant responses regarding the sensation of ease in moving their joint. The WOMAC Stiffness Score is a validated 100 mm visual analog scale (VAS) from 0 mm = No Stiffness to 100 mm = Extreme Stiffness. A negative value for the change from Baseline indicates improvement in WOMAC Stiffness Score. A larger negative value indicates less stiffness, and a better outcome.	26 Weeks

WOMAC Total Score combines the three 0-to-100 point scores from the WOMAC Pain Score, the WOMAC Stiffness Score, and the WOMAC Function Score to calculate a TOTAL Score from 0 = No Symptoms to 100 = Highest Degrees of Pain, Stiffness and Functional Limitation Symptoms.; A negative value for the change from Baseline in WOMAC Total Score indicates reduction in pain, stiffness, and improved function. A larger negative value indicates a better overall clinical outcome.	26 Weeks
Secondary	Change From Baseline in the Patient Global Assessment (PGA) Score	The change from Baseline in knee pain post-treatment as measured by the Patient Global Assessment (PGA) Score comparing the Cingal, TH, and Placebo arms. PGA Score records participant responses to their assessment of how much their STUDY (treated) knee is bothering them today . The PGA Score is a validated 100 mm visual analog scale (VAS) from 0 mm = No Pain to 100 mm = Extreme Pain.; A negative value for the change from Baseline indicates improvement in PGA Score. A larger negative value indicates less pain, and a better clinical outcome.	26 Weeks
Secondary	Change From Baseline in the Evaluator Global Assessment (EGA) Score	The change from Baseline in knee pain post-treatment as measured by the Evaluator Global Assessment (EGA) Score comparing the Cingal, TH, and Placebo arms. EGA Score records the Study Evaluator's assessment of how much the patient's STUDY (treated) knee is bothering them today . The EGA Score is a validated 100 mm visual analog scale (VAS) from 0 mm = No Pain to 100 mm = Extreme Pain.; A negative value for the change from Baseline indicates improvement in EGA Score. A larger negative value indicates less pain, and a better clinical outcome.	26 Weeks
Secondary	The Usage of Rescue Medication (Acetaminophen/Paracetamol) at 26 Weeks	The usage of Rescue Medication (RM) as based on the average number of acetominophen/paracetamol pills taken among participants at 26 Weeks post treatment comparing between the Cingal, Triamcinolone Hexacetonide (TH) and Placebo arms.; A smaller value in average RM indicates that fewer pills were taken by the participants, which may correlate to a better clinical outcome in terms of pain.	26 Weeks
