What is the purpose of this trial?

This trial explores the effectiveness of platelet-rich plasma (PRP) injections for shoulder osteoarthritis, a condition causing joint pain and stiffness. It compares different doses of PRP to saline to determine the most effective option. Participants who have experienced shoulder pain for over three months, found no relief with treatments like physical therapy, and received temporary relief from specific injections might be suitable candidates. The goal is to determine if PRP offers a better treatment option for those struggling with this type of shoulder pain. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, and this research aims to understand how it benefits more patients.

Do I have to stop taking my current medications for the trial?

The trial requires you to stop taking non-steroidal anti-inflammatory drugs (like ibuprofen) for 2 weeks before and 1 month after the injection. If you have used steroid injections or hyaluronic acid recently, you may also need to wait before participating.

What is the safety track record for these treatments?

Research has shown that platelet-rich plasma (PRP) therapy has been studied for various joint issues, such as osteoarthritis (OA). Studies suggest that PRP can aid in tissue healing and symptom relief. However, safety considerations are important when evaluating treatments like PRP.

High-dose PRP has been associated with some side effects, including possible infections, swelling, allergic reactions, and small lumps. Despite these, PRP remains promising due to its potential benefits.

Low-dose PRP has shown similar side effects, such as infections and swelling. However, patients generally tolerate PRP treatments well. While these side effects can occur, not everyone experiences them.

This trial is in a later phase, indicating that more is known about the treatment's safety. PRP is already used for other conditions, suggesting it has been fairly safe for many patients. Prospective participants should discuss any concerns with a healthcare provider before joining a trial. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about using platelet-rich plasma (PRP) injections for shoulder osteoarthritis because they offer a potentially regenerative treatment option. Unlike standard treatments like NSAIDs or corticosteroid injections that mainly relieve pain and reduce inflammation, PRP harnesses the body's own healing properties. With PRP, especially the high-dose variant, a concentrated amount of platelets is introduced into the joint, which may help repair tissues and slow disease progression. This approach could provide longer-lasting relief and improved joint function compared to conventional therapies.

What evidence suggests that this trial's treatments could be effective for shoulder osteoarthritis?

This trial will compare the effects of high-dose PRP, low-dose PRP, and a saline control for shoulder osteoarthritis. Research has shown that platelet-rich plasma (PRP) injections can help with various shoulder issues. In some cases of partial rotator cuff tears, PRP led to better results than corticosteroids. Studies also suggest that PRP can improve patient-reported outcomes more effectively than hyaluronic acid for joint problems. High-dose PRP, which participants in this trial may receive, is thought to aid in tissue healing. Low-dose PRP, another treatment option in this trial, has effectively reduced pain and improved function in muscle and joint conditions. Both high-dose and low-dose PRP appear promising for treating osteoarthritis by helping with pain relief and joint function. ^{2 4 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-100 with shoulder osteoarthritis who've had pain for at least 3 months despite trying physical therapy and other conservative treatments. Participants need an email or network access, an MRI of the affected joint, and a pain score of at least 5/10 due to the condition. They must have experienced temporary relief from a diagnostic joint injection. Those on NSAIDs can't join, nor can those involved in workers' comp claims, recent recipients of certain injections or treatments, or individuals with uncontrolled illnesses.

What Are the Treatments Tested in This Trial?

Interventions

• High-dose PRP
• Low-dose PRP
• Saline

Trial Overview The study tests single injections of two different doses of PRP (Platelet-Rich Plasma) against saline to see which is more effective for shoulder osteoarthritis. Previous studies used low-dose PRP; this one includes both low-dose (~3X concentration) and high-dose PRP to compare outcomes.

How Is the Trial Designed?

Group I: Low-dose PRP Experimental Treatment 1 Intervention

Patients will receive a single injection of 6 ml low-dose platelet-rich plasma (PRP) into the glenohumeral joint. Low-dose is defined as a platelet yield of 3X (i.e., 3-fold increase in platelets in PRP compared to whole blood).

Group II: High-dose PRP Experimental Treatment 1 Intervention

Patients will receive a single injection of 6 ml high-dose platelet-rich plasma (PRP) into the glenohumeral joint. High-dose is defined as a platelet yield of 12X (i.e., 12-fold increase in platelets in PRP compared to whole blood).

Group III: Saline control Placebo Group 1 Intervention

Patients will receive a single injection of 6 ml saline into the glenohumeral joint.

High-dose PRP is already approved in United States, European Union for the following indications:

Approved in United States as Platelet-Rich Plasma for:

• Orthopedic/musculoskeletal indications including osteoarthritis of the knee, ankle, hip, and shoulder

Approved in European Union as Platelet-Rich Plasma for:

Intra-articular injections of platelet-rich plasma (PRP) are considered an effective symptomatic treatment for early to moderate knee osteoarthritis, supported by strong expert agreement and a high level of evidence (1A).

A recommended treatment sequence includes 1-3 PRP injections, and leucocyte-poor PRP is preferred for better outcomes, although many recommendations are based on expert opinion rather than high-level evidence.

In a study involving 60 patients with adhesive capsulitis of the shoulder, a single intra-articular injection of platelet-rich plasma (PRP) was found to be more effective than corticosteroid (CS) injections in reducing pain and improving shoulder function over a 12-week period.

Patients receiving PRP showed greater improvements in pain scores and range of motion compared to those receiving corticosteroids, with no major complications reported, indicating that PRP may be a safer and more effective treatment option for this condition.
