Precision Assessment of Platelet Rich Plasma for Joint Preservation

Study Purpose

Knee Osteoarthritis (OA) is a leading cause of premature disability in Veterans who develop knee OA at higher rates and younger ages than the population in general. For those with symptomatic early knee OA, who are years to decades away from meeting clinical indications for knee replacement surgery, knee injections have been a key treatment option. In recent years, platelet rich plasma (PRP) injections have gained increasing attention for improving pain and function in patients with knee OA. Basic science studies also suggest that PRP may also potentially stimulate repair responses to articular cartilage. However, the mechanisms of action of PRP in the treatment of knee OA are unknown. Because autologous blood is used, the PRP composition differs between patients. It is also unknown whether these differences in PRP composition affect clinical outcomes. This study will address these gaps and provide critical new and objective information on PRP treatment effects in Veterans and additional women with early knee OA important to improving clinical use of this new treatment.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Observational
Eligible Ages 30 Years - 70 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03460236
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Because very little is known about either the mechanisms of action or objective clinical outcomes of PRP treatment for knee OA, the investigators propose a prospective "pre-post" study that will permit us to identify areas where more rigorous clinical outcomes and mechanistic research may be warranted. The proposed work includes special elements of:

  • (1) quantitative metrics to assess clinical outcomes, (2) correlation of candidate beneficial proteins with clinical outcomes, and (3) proteomic evaluation of the injected PRP.
This work will use an innovative multi-disciplinary, personalized approach to evaluate the effects of PRP composition on both function, as assessed by patient-reported outcomes and gait analysis, and cartilage matrix structure as assessed by quantitative MRI
