简要总结

The purpose of this study is to determine the safety and effectiveness of micronized dehydrated human amnion chorion membrane as compared to the 0.9% Sodium Chloride Injection, USP placebo control for the treatment of knee osteoarthritis

详细描述

Each subject will receive 1 injection (micronized dHACM or placebo) and be evaluated for efficacy and safety during a 12-month observation period. A second injection (open-label access to micronized dHACM) will be offered to all subjects at the 180-day, 270-day, and 365-day time points, it may only be used once. Blinding for the first injection treatment allocation will be maintained until the end of the study.

Subjects who receive the open-label access treatment will continue to be followed for 180 days after this second injection, regardless of the time at which treatment was received.

结局指标

主要结局

Primary Safety Endpoint: Number of Participants With Serious Adverse Events (SAEs)

时间窗: 365 days

Number of Participants with At Least 1 Serious Treatment Emergent Adverse Event (TEAE) Reported

Primary Efficacy Endpoint: Change From Baseline in Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index at 90 Days

时间窗: 90 days

Western Ontario and McMaster Universities Arthritis Index (WOMAC) evaluation of Hip and Knee Osteoarthritis. Self-administered questionnaire consisting of 24 questions divided into 3 subscales: * Pain (5 questions) * Stiffness (2 questions) * Physical Function (17 questions) The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. A sum of the scores for all three subscales gives a total WOMAC score, with a possible total score range of 0-96. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

Primary Safety Endpoint: Number of Participants With Adverse Events (AEs)

时间窗: 365 days

Number of Participants with At Least 1 Treatment Emergent Adverse Event (TEAE) Reported

Primary Efficacy Endpoint: Change From Baseline in Visual Analog Scale (VAS) for Pain at 90 Days

时间窗: 90 days

Visual Analog Scale (VAS): 0 to 100 mm horizontal visual analog scale with a higher score indicating greater pain

Primary Safety Endpoint: Number of Participants With Unanticipated Adverse Events

时间窗: 365 days

Number of Participants with At Least 1 Unanticipated Treatment Emergent Adverse Event (TEAE) Reported

次要结局

  • Secondary Endpoint: Change From Baseline in Visual Analog Scale (VAS) at 180 Days(180 days)
  • Secondary Endpoint:Change From Baseline in WOMAC at 180 Days(180 days)
