Profiling knee osteoarthritis patients to predict response to regenerative treatment

Immuno-based Profiling of knEe OA Patients to Predict reSponse to Regenerative Treatment

Observational Istituto Clinico Humanitas · NCT06384040

This study is trying to see if certain characteristics of people with knee osteoarthritis can help predict how well they will respond to platelet-rich plasma injections as a treatment.

What this trial studies

This observational study aims to profile patients with knee osteoarthritis (OA) to predict their response to platelet-rich plasma (PRP) injections, a minimally invasive treatment option. By analyzing clinical data, imaging, and specific biomarkers related to inflammatory and antioxidant pathways, the study seeks to identify unique profiles that can guide personalized treatment approaches. The goal is to enhance the effectiveness of immunomodulatory and regenerative therapies for knee OA, addressing the current lack of predictive biomarkers in this condition.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 40 to 75 with grade 2-3 knee osteoarthritis who have failed at least one conservative therapy.

Not a fit: Patients with active infections, chronic inflammatory diseases, or recent knee surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized treatment options for patients with knee osteoarthritis.

How similar studies have performed: While the approach of using PRP injections is established, the specific profiling for predictive response in knee OA is relatively novel and has not been extensively tested.

Inclusion Criteria:

* men/women, aged \>40 - \<75 years), OA grade 2-3, BMI \<40, baseline WOMAC PAIN \>1.75 -\<4, \>1 conservative therapy failed. Diagnosis of knee OA according to the American College of Rheumatology (ACR) classification criteria (Altman, 1986) .
