About this study

Official title: A Randomized, Multi-center, Double Blind, Parallel Study to Examine the Effect of Lipogems Processed Microfragmented Adipose Tissue in Comparison to Corticosteroid for the Treatment of Knee Osteoarthritis

The goal of this clinical trial is to examine the effect of a single autologous, intra-articular injection of MFat versus corticosteroid injection for the treatment of pain and function associated with K/L grade 2/3 knee Osteoarthritis.

Participants will receive an injection of MFat or a corticosteroid.

Read the detailed description

This study will investigate The Lipogems System in a clinical study to examine the effect of micro fragmented adipose tissue processed using The Lipogems System in comparison to corticosteroid for the treatment of knee osteoarthritis. This study will be randomized and double-blinded. The subjects will be randomized at a 2:1 ratio (investigational to control) and will enroll 173 patients at up to 20 sites in the United States.

Being tested
Microfragmented Adipose Tissue, Corticosteroid
Medical subject headings
Osteoarthritis, Knee

Study groupRoleWhat they receive
Corticosteroid InjectionActive comparatorThe cases assigned to this group will be injected intra-articularly in the knee with a corticosteroid. It will be administered once at the baseline visit of the study.
Receives: Drug: Corticosteroid
Microfragmented Adipose Tissue (Mfat)ExperimentalInjection of Microfragmented Adipose Tissue derived using Lipogems® Kit The cases assigned to this group will be injected intra-articularly with Lipogems®. The patients will undergo lipoaspiration of their own adipose tissue for Mfat then this Mfat will be injected intra-articularly in the knee. It will be administered once at the baseline visit of the study.
Receives: Device: Microfragmented Adipose Tissue

What is being measured

The primary outcome is the main question the study is designed to answer.

    The change from baseline to Month 12 for the Western Ontario and McMaster Universities Osteoarthritis Index pain (WOMAC-A) subscale score (superiority); Scale = 0-100, where 100 is extreme pain

    Measured: 12-month visit

  2. WOMAC-C Subscale Score

    The change from baseline to Month 12 for the Western Ontario and McMaster Universities Osteoarthritis Index function (WOMAC-C) subscale score (non-inferiority), scale 0-100, where 100 is extreme difficulty performing a function.

    Measured: 12-month visit

Secondary outcomes (3)

  1. Change in WOMAC-A Pain Sub Score

    Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC-A) Pain sub score at 6, 9 and 12-month follow-up visits compared to baseline, Scale 1-100, where 100 is extreme pain.

    Measured: 12-month visit

  2. Change in WOMAC-C Function Sub Score

    Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC-C) Function sub score at 6, 9, and 12-month follow-up visits compared to baseline; Scale 1-100, where 100 is extreme difficulty performing a function

    Measured: 12-month visit

  3. Change in Total WOMAC scores

    Change in Total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at, 6, 9, and 12-month follow-up visits compared to baseline; Scale 1-100, where 100 is either extreme pain (WOMAC-A), extreme stiffness (WOMAC-B) or extreme difficulty performing a function (WOMAC-C).

    Measured: 12-month visit

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Microfragmented Adipose Tissue and Corticosteroid in people with Knee Osteoarthritis and Osteo Arthritis Knee, run by Lipogems International spa at 18 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 45 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Western Ontario and McMaster Universities Osteoarthritis Index Pain (WOMAC-A) VA3.1 Score (time frame: 12-month visit). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05660772.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2025.
