What is the purpose of this trial?

This trial tests a new treatment using a fractional CO2 laser for men with Peyronie's Disease, which causes painful curvature of the penis due to scar tissue. The goal is to determine if this laser therapy can safely reduce curvature and improve quality of life without surgery. Participants will receive either the laser treatment or a sham (fake) treatment for comparison. Men who have had Peyronie's Disease for at least a year, with a stable condition and a curvature between 30º and 90º, might be suitable candidates for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative therapy.

Will I have to stop taking my current medications?

The trial requires that you have not used any oral or topical treatments for Peyronie's Disease in the last 3 months, and no intralesional therapies in the last 3 months. If you are currently using these treatments, you may need to stop them before joining the trial.

What prior data suggests that fractional CO2 laser therapy is safe for treating Peyronie's Disease?

Research has shown that fractional CO2 laser therapy could safely and effectively treat Peyronie's Disease (PD). In earlier studies, men experienced a reduction in penile curvature without major safety concerns. Most patients tolerated the treatment well, though a few reported minor side effects. For instance, one individual experienced penile pain post-treatment, and two other minor issues were noted. Overall, the treatment is considered minimally invasive, posing less risk and not requiring surgery. Promising results after 52 weeks suggest it could be a viable option for managing PD. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for Peyronie's Disease, which often involve oral medications, injections, or surgery, fractional CO2 laser therapy offers a non-invasive approach. This laser therapy targets the plaque tissue directly, potentially reducing curvature and improving symptoms without the need for more aggressive interventions. Researchers are excited because this method could offer a quicker recovery time and fewer side effects compared to traditional options, making it a promising alternative for patients.

What evidence suggests that fractional CO2 laser therapy might be an effective treatment for Peyronie's Disease?

Research has shown that fractional CO2 laser therapy, which participants in this trial may receive, could be a promising treatment for Peyronie's Disease (PD). In earlier studies, all patients experienced a decrease in the bend of their penis, a common issue in PD. These studies suggest that this laser treatment is safe and non-surgical. Positive results appeared at both 24 and 52 weeks after treatment, with patients noticing improvements. This therapy targets and reduces the abnormal scar tissue, a main problem in PD. Overall, fractional CO2 laser therapy might become a well-tolerated option for people with this condition. ^{2 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for men with chronic phase Peyronie's Disease, which causes penile deformity and can affect sexual function. Participants will undergo assessments of their condition, including measurements and questionnaires about erectile function and the impact of PD on their lives.

What Are the Treatments Tested in This Trial?

Interventions

• Fractional CO2 Laser

Trial Overview

The study tests Fractional CO2 Laser Therapy as a non-invasive treatment to reduce abnormal collagen in scar tissue caused by Peyronie's Disease. Patients will receive three laser therapy sessions over several weeks with follow-ups at 24 and 52 weeks to evaluate safety and effectiveness.

How Is the Trial Designed?

Group I: Fractional CO2 laser therapy group Experimental Treatment 1 Intervention

Patients will receive three treatments with fractional CO2 laser to identified Peyronie's plaque tissue

Group II: Sham control group Placebo Group 1 Intervention

Patients will receive sham treatment with non-invasive treatment mimicking CO2 laser therapy
