What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how Platelet-Rich Plasma (PRP) injections can aid men with Peyronie's Disease (PyD), a condition where scar tissue causes curved and painful erections. The study involves two groups: one receives the PRP treatment first, followed by a placebo (inactive substance), while the other starts with the placebo and later receives the PRP treatment. Men diagnosed with Peyronie's Disease and significant penile curvature may be suitable candidates. Participants must adhere to all study-related tests and procedures. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

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

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot be actively on anticoagulation during the injections, except for aspirin 81 mg, which is allowed.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot be on anticoagulation (blood thinners) during the time of the injections, except for low-dose aspirin (81 mg).

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that platelet-rich plasma (PRP) injections are generally safe for treating conditions like Peyronie's Disease. In past studies, patients experienced only minor and temporary side effects, such as mild pain or swelling at the injection site, which resolved on their own. Other research supports the safety of PRP, indicating it is well-tolerated by most people. While more studies are needed to fully confirm these findings, current evidence suggests that PRP is a safe option for those considering joining a clinical trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Peyronie's Disease?

Researchers are excited about using autologous Platelet Rich Plasma (PRP) for treating Peyronie's Disease because it represents a more natural and potentially less invasive option compared to current treatments like surgery or medication. Unlike these traditional methods, PRP is derived from the patient's own blood, which is thought to promote healing by delivering a concentrated dose of growth factors directly to the affected area. This approach not only minimizes the risk of adverse reactions but also leverages the body's own healing mechanisms. Additionally, PRP might offer a quicker recovery time and fewer side effects, making it an attractive alternative for patients seeking relief from this condition.

What evidence suggests that this treatment might be an effective treatment for Peyronie's Disease?

Research shows that using a person's own blood in Platelet-Rich Plasma (PRP) injections might help men with Peyronie's Disease. Studies have found that PRP can improve the shape and thickness of the penis, which are often affected by the disease. This trial will test two different sequences of treatment: one group will receive the Autologous PRP intervention first, followed by a placebo, while the other group will receive the placebo first, followed by the Autologous PRP intervention. The treatment involves taking a sample of the patient's blood to create a concentrated plasma, which may aid healing and reduce scarring. Patients who have tried this treatment reported improvements in the curve of their penis and fewer symptoms. These findings suggest that PRP could be a promising option for those dealing with Peyronie's Disease. ^{2 6 7 8 9}

Trial Overview

The trial is investigating the effects of injecting Platelet-Rich Plasma (PRP) into men with Peyronie's Disease compared to saline solution injections. The goal is to see if PRP can improve the condition.

How Is the Trial Designed?

Group I: Experimental: Placebo followed by Autologous PRP Group Experimental Treatment 2 Interventions

Participants in this group will receive the placebo intervention first, followed by the Autologous PRP intervention 3 months later.

Group II: Experimental: Autologous PRP followed by Placebo Group Experimental Treatment 2 Interventions

Participants in this group will receive the autologous intervention first, followed by the placebo intervention 3 months later.

Autologous Platelet Rich Plasma is already approved in United States, European Union for the following indications:

Approved in United States as Platelet-Rich Plasma for:

• None FDA-approved; used off-label for various conditions including orthopedic and dermatological applications

Approved in European Union as Platelet-Rich Plasma for:

Intralesional injection of platelet-rich plasma for Peyronie's disease has shown early signs of safety based on observations from an ongoing clinical trial.

Efficacy data for this treatment are still pending and will be available upon completion of the trial.

A Phase 2 Randomized, Placebo-controlled Crossover Trial to Evaluate Safety and Efficacy of Platelet-rich Plasma Injections for Peyronie's Disease: Clinical Trial Update. Chu, KY., Molina, ML., Ledesma, B., et al.[2023]

In a study of 17 patients receiving platelet rich fibrin matrix (PRFM) injections for urologic conditions, only minor adverse events like mild pain and bruising were reported, indicating a good safety profile.

No decline in erectile function was observed in patients evaluated with the International Index of Erectile Function (IIEF-5) scores, suggesting that PRFM may be a feasible treatment option for erectile dysfunction and other urologic issues.

In a study involving 17 patients with Peyronie's disease, three intra-platelet-rich plasma (PRP) injections were administered, showing no side effects and significant improvements in the Peyronie's Disease Questionnaire (PDQ) scores after treatment.

The angle of curvature of the penis decreased significantly by 11.8°, and erectile function improved, with the IIEF-EF score increasing by an average of 5 to 7 points at various follow-up intervals, indicating potential efficacy of PRP injections in treating Peyronie's disease.

In a study involving 20 male rats, intratunical injections of platelet-rich plasma (PRP) did not show significant differences in fibrosis or collagen ratios compared to the Peyronie's disease (PD) group, suggesting that PRP may mimic PD effects rather than provide therapeutic benefits.

This research indicates that PRP could serve as a cost-effective and accessible model for studying Peyronie's disease treatment, although its efficacy in actually treating the condition remains unclear.

The combination of low intensity external shock wave therapy (Li-ESWT) and platelet-rich plasma (PRP) therapy significantly improved outcomes in patients with acute Peyronie's disease, including reductions in plaque size and penile curvature, as well as enhancements in erectile function and pain scores.

This treatment was found to be safe, with no reported side effects such as ecchymosis or hematoma at the injection sites, indicating a favorable safety profile for early intervention in Peyronie's disease.

In a study involving 65 patients with Peyronie's disease, repeated intralesional injections of platelet-rich plasma (PRP) significantly improved penile curvature by an average of 16.88° to 17.27°, demonstrating both safety and efficacy over a 12-month period.

Additionally, the treatment led to a notable reduction in pain during intercourse, decreasing from 70.7% to 34.25%, with over half of the patients reporting easier sexual intercourse, highlighting the positive impact on quality of life.

Platelet-rich plasma (PRP) therapy shows promise for treating erectile dysfunction (ED) and Peyronie's disease (PD) due to its regenerative properties, with a review of 10 trials (4 preclinical and 6 clinical) indicating no adverse reactions associated with its use.

However, the studies reviewed had limitations such as small sample sizes and short follow-up periods, suggesting that while PRP has potential, more robust research is needed to confirm its safety and effectiveness in treating male sexual dysfunction.
