Autologous Culture Expanded Adipose Derived MSCs for Treatment of Painful Hip OA

Phase 1
Active, not recruiting
Conditions
Osteoarthritis, Hip
Interventions
Registration Number
NCT03608579
Lead Sponsor
Mayo Clinic
Brief Summary

Will injection(s) of autologous culture-expanded AMSCs be safe and efficacious for treatment of painful Hip OA, and if so, which dosing regimen is most effective?

Detailed Description

This phase I study will enroll 24 subjects with mild to moderate osteoarthritis of the hip. Subjects will receive either a single dose of 30 million autologous culture-expanded adipose-derived mesenchymal stromal cells (AMSCs), or two doses of AMSCs (with one month interval between doses) via ultrasound guided intra-articular hip injection. Patients will be followed for 24 months past their last injection to determine the local and systemic safety of single and two-dose injections of AMSCs in the treatment of symptomatic hip OA.

Primary Outcome Measures
NameTimeMethod
Nature, incidence and severity of adverse events (AEs)For a period of 2 years following last injection

Defined as any untoward or undesirable medical occurrence in the form of signs, symptoms, abnormal findings, or diseases that emerge or worsen relative to baseline (i.e., if present upon study entry) during the study regardless of causal relationship.

Methods i. Spontaneous subject reports ii. Subject interview by study personnel iii. Clinical examination during face-to-face clinic follow-ups

Secondary Outcome Measures
NameTimeMethod
Change in cartilage thicknessBaseline, 6 months, and 12 months post-treatment cycle

Cartilage thickness on MRI

Change in radiographic joint morphologyBaseline, 6 months, and 12 months post-treatment cycle

Evaluation of joint morphology on hip X-rays, including standing antero-posterior, lateral, and false profile

Change in synovial fluid biomarkers within the target hipBaseline at the time of AMSC injection, At time of second injection (1 month status post first injection) in 2-injection group

Synovial fluid from attempted aspiration at the time of injection (and re-injection for the two injection cohort) will be analyzed for cells, cytokines, growth factors, and other similar biomarkers.

Change in Visual Analog Scale (VAS) for pain in the target hip following completion of treatment cyclesBaseline, 6 weeks, 6 months, 12 months post-treatment cycle

100 mm Visual Analog Scale. Range: 0 to 100 mm. Lower is better, higher is worse.

Change in modified Harris Hip Score (mHHS) in the target hip following completion of treatment cyclesBaseline, 6 weeks, 6 months, 12 months post-treatment cycle

modified Harris Hip Score (mHHS). Score 0 to 100. Higher is better, lower is worse.

Change in cartilage volumeBaseline, 6 months, and 12 months post-treatment cycle

Cartilage volume on MRI

Change in cartilage morphologyBaseline, 6 months, and 12 months post-treatment cycle

Cartilage morphology on MRI

Change periarticular soft-tissuesBaseline, 6 months, and 12 months post-treatment cycle

Evaluate periarticular tissues on MRI (i.e. visible synovitis)

Change in Tegner activity scale in the target hip following completion of treatment cyclesBaseline, 6 weeks, 6 months, 12 months post-treatment cycle

Tegner activity scale (Level 0 to Level 10). Higher is better, lower is worse.

Change in Hip disability and osteoarthritis Outcome Score (HOS) in the target hip following completion of treatment cyclesBaseline, 6 weeks, 6 months, 12 months post-treatment cycle

Hip disability and osteoarthritis Outcome Score (HOS). Score 0 to 100. Higher is better, lower is worse.

Change in subchondral bone morphologyBaseline, 6 months, and 12 months post-treatment cycle

Subchondral bone morphology (i.e. edema) on MRI
