What is the purpose of this trial?

This trial aims to compare two treatments for knee osteoarthritis pain and function: a corticosteroid injection and an injection of microfragmented adipose tissue (Mfat), derived from the patient's own fat. Participants will receive one of these injections to determine which is more effective in easing symptoms. The study seeks individuals with knee osteoarthritis who have tried other treatments, such as physical therapy and over-the-counter pain medication, for at least three months without success. As a Phase 3 trial, this study serves as the final step before FDA approval, providing participants an opportunity to access potentially effective treatments early.

Will I have to stop taking my current medications?

Participants must stop using over-the-counter pain medications like Acetaminophen or NSAIDs for 7 days before any follow-up visit and abstain from NSAIDs for 7 days before and 2 weeks after the injection. Prescription pain or anti-inflammatory medications must be stopped for the study duration, except for Tramadol immediately after the procedure.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that injections of microfragmented adipose tissue (MFat) are generally safe for treating knee osteoarthritis. MFat uses a person's own fat tissue, reducing the risk of immune problems and adverse reactions. Specifically, MFat injections have improved knee function and reduced pain for up to four years, with no major safety concerns reported.

Corticosteroid injections, another well-known treatment for knee pain, have been used for many years. They are usually well-tolerated, though some people might experience temporary side effects like joint pain or swelling after the injection.

Both treatments have demonstrated promising safety results, making them good options for those considering participation in a trial for knee osteoarthritis.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about Microfragmented Adipose Tissue (MFat) for knee osteoarthritis because it uses a unique approach by leveraging the body’s own fat tissue to potentially heal and reduce inflammation in the knee. Unlike traditional treatments like corticosteroid injections, which primarily focus on reducing inflammation temporarily, MFat involves extracting and processing a patient’s own fat tissue, which is then injected back into the knee. This approach not only offers a natural alternative but is also believed to provide longer-lasting relief by directly promoting tissue repair and regeneration. Additionally, using the body’s own cells minimizes the risk of rejection and adverse reactions, making it a promising new avenue for osteoarthritis treatment.

What evidence suggests that this trial's treatments could be effective for knee osteoarthritis?

This trial will compare the effectiveness of microfragmented adipose tissue (MFat) and corticosteroid injections for knee osteoarthritis. Research has shown that MFat can help with knee osteoarthritis, with 68% of patients reporting improvement four years after treatment. This method uses the patient's own fat to reduce pain and improve knee function. Studies using the Knee injury and Osteoarthritis Outcome Score (KOOS) have consistently demonstrated benefits over time. MFat has also aided patients with related conditions like atherosclerosis. Overall, MFat appears to offer significant benefits for individuals with knee osteoarthritis.

Participants in this trial may also receive corticosteroid injections, another common treatment for knee osteoarthritis. These injections reduce inflammation and pain, but the relief might be temporary and may not address the underlying issue. Both treatments can alleviate pain, but their long-term effects may differ.15678

Are You a Good Fit for This Trial?

Adults over 18 with knee osteoarthritis (Grade 2-3) who've had pain despite trying physical therapy and NSAIDs for at least 3 months can join. They must be able to attend follow-ups, read English, and not be pregnant or breastfeeding unless postmenopausal or sterilized. Excluded are those with severe obesity, certain knee deformities, autoimmune diseases needing immunosuppressants, allergies to specific drugs used in the trial, uncontrolled diabetes or blood pressure issues, recent injections or surgeries on the knee.

What Are the Treatments Tested in This Trial?

Interventions

  • Corticosteroid
  • Microfragmented Adipose Tissue
Trial Overview The study is testing a single injection treatment for knee osteoarthritis pain and function: one group receives microfragmented adipose tissue (MFat), while another gets a corticosteroid injection. The effectiveness of these treatments will be compared.

Published Research Related to This Trial

In a study involving 84 patients with symptomatic knee osteoarthritis, a 10-mg dose of triamcinolone acetonide was found to be non-inferior to a 40-mg dose in reducing pain after 12 weeks, indicating that lower doses can be just as effective.
Both the 10-mg and 40-mg doses significantly improved pain and quality of life for patients, suggesting that lower doses may provide a safer option without compromising efficacy.
The efficacy of intra-articular triamcinolone acetonide 10 mg vs. 40 mg in patients with knee osteoarthritis: a non-inferiority, randomized, controlled, double-blind, multicenter study.Utamawatin, K., Phruetthiphat, OA., Apinyankul, R., et al.[2023]
In a phase IIa study involving 24 patients with bilateral knee osteoarthritis, the intra-articular injection of triamcinolone acetonide extended release (TA-ER) was well tolerated and showed a lower peak plasma concentration of the drug compared to traditional triamcinolone acetonide crystalline suspension (TAcs).
The study demonstrated that TA-ER resulted in lower systemic exposure to triamcinolone acetonide after bilateral injections, suggesting it may be a safer option for patients needing simultaneous treatment in both knees.

A 40 mg intra-articular injection of methylprednisolone acetate (MPA) can provide clinical benefits for knee osteoarthritis symptoms, but careful consideration of factors like pain severity and individual patient circumstances is crucial for effectiveness.
There are significant safety concerns and contraindications associated with MPA injections, especially regarding patients on anticoagulants, highlighting the need for individualized treatment plans and thorough risk-benefit evaluations.
