Detailed Description

PURPOSE OF THE STUDY The goal of this clinical trial is to evaluate the safety and tolerability of a treatment called OA-SYS for moderate to severe osteoarthritis (OA) of the knee. Osteoarthritis is a common condition that affects the joints and can cause significant pain and disability, especially in older adults. The study aims to see if OA-SYS is a safe and effective treatment option for people with knee osteoarthritis.

STUDY TREATMENT

Participants in this study will receive the OA-SYS treatment, which involves the use of adult stem cells (ASCs). The main questions the study aims to answer are:

  • Is OA-SYS safe and well-tolerated by participants with moderate to severe knee osteoarthritis?
  • Does OA-SYS help reduce the symptoms and improve the function of the knee joint?

Participants will:

  • Receive the OA-SYS treatment, which includes adult stem cells, administered to the knee joint.
  • Attend regular clinic visits for check-ups and monitoring.
  • Report any side effects or changes in their condition throughout the study period.

RANDOMIZATION AND BLINDING This is a phase II open-label clinical trial, blinding is not applicable to this study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Presence of Adverse Events
Time Frame: 52 weeks
Presence of adverse events in less than 5% of the study population, as a measure of safety
52 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in NSAIDs Use
Time Frame: 52 weeks
Change in NSAIDS use, until study completion
52 weeks
Change in The Western Ontario and McMaster Universities Arthritis Index (WOMAC)
Time Frame: 52 weeks
The WOMAC score is used in clinical trials to measure the condition of patients with osteoarthritis. It's a patient-reported outcome measure where 0 represents the worst possible score and 100 represents the best possible score. A higher score indicates worse pain, stiffness, and functional limitations.
52 weeks
Change in the Visual Analog Scale (VAS)
Time Frame: 52 weeks
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain". A lower scale indicates better progress, which indicates less pain.
52 weeks

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of treatment-emergent adverse events (TEAEs)
Time Frame: 52 weeks
TEAEs are defined as adverse events with an onset on or after the time of first administration of the treatment.
52 weeks
Incidence of withdrawals due to adverse events (AEs)
Time Frame: 52 weeks
Reported withdrawals from the study due to adverse events, as a measure of safety.
52 weeks
