PAF for the Treatment of Osteoarthritis

Phase 1
Completed
Conditions
Osteo Arthritis Knee
Interventions
Other: Standard of Care
Biological: Amniotic Fluid Injection
Registration Number
NCT04886960
Lead Sponsor
University of Utah
Brief Summary

This is a Phase I/II Randomized Double-Blinded Standard of Care (Corticosteroid) vs. Sterile Amniotic Fluid for Osteoarthritis

Detailed Description

This study will look at blinded standard of care (SOC) steroid injection vs. amniotic fluid injection (pAF) to treat and reduce osteoarthritis (OA) inflammation and pain. The main objectives of this study are to establish the safety and tolerability of allogeneic intra-articular pAF injections. Secondary objectives include pain levels and functional outcome scoring in patients over a 12 month time frame.

Primary Outcome Measures
NameTimeMethod
Repeat allogeneic intra-articular injection within 6 months.6 months

Participants in both the SOC and pAF treatment arms may require and/or request rescue medication (i.e. SOC injection) at any time and will be given per PI discretion as part of standard of care. The clinicians will not know which study arm the study participant is in but will treat the participant with the SOC injection. This information will be documented and collected in the Electronic Medical Record (EMR), as well as the study's electronic data capture system. Participants will not be given any additional pAF injections throughout the study period.

The participant will continue to be treated with SOC injections as needed. The outcome will be an indicator of whether or not a subject received a rescue medication within 6 months.

Secondary Outcome Measures
NameTimeMethod
Knee Injury and Osteoarthritis Outcome Score (KOOS)6 months

Scale 0-100, where higher numbers indicate less problems. The KOOS is a survey that assesses joint symptoms, pain, pain during daily activities, physical function in daily living, as well as physical function during sports or recreational activities.

Visual Analog Scale for pain (VAS Pain)6 months

Scale 0-10, where higher numbers indicate more pain. Pain will be measured by the Visual Analog Scale for pain (VAS Pain). This will consist of a comparison of mean values for VAS scoring scales pre-injection and at the 6 month follow-up assessment. Clinically significant outcomes will be determined based on the minimal clinically important difference (MCID) occurring for each respective scale, which is defined as the smallest reported measurement tool used to quantify perceived level of pain, graded on a scale from 0 to 10 with 0 representing no pain and 10 representing the worse pain possible, and with precise measurement of the marked pain level's distance from 0 comprising the pain level.

Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function Computer Adaptive Test (PF-CAT)6 months

Scale 0-100, where higher numbers indicate better physical functioning. The PF-CAT is a bank of questions related to physical function. It is a computerized adaptive test that asks the patient to self-report capabilities rather than actual performance of physical activities. It includes functioning of upper extremities, lower extremities, and central regions and also assess instrumental activities of daily living, such as running errands.

Single Assessment Numerical Evaluation (SANE)6 months

Scale 0-100, where higher numbers indicate more pain. The SANE asks the patient to evaluate their percentage of normal on the affected joint of region of interest. This is a one-question survey.
