What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a laser therapy to treat men with Peyronie's Disease by breaking down scar tissue in the penis, aiming to improve its shape and function without invasive procedures. Laser therapy has been proposed with success in the treatment of Induratio Penis Plastica (IPP), also called Peyronie's Syndrome.

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 have used oral or topical agents for Peyronie's Disease within 3 months before the study.

Is CO2 laser therapy generally safe for humans?

A study involving 12 patients used carbon dioxide laser therapy to treat Peyronie's plaque, and it was described as a versatile procedure, suggesting it was safely applied in these cases.12345

How does CO2 laser therapy differ from other treatments for Peyronie's disease?

CO2 laser therapy for Peyronie's disease is unique because it uses a focused laser beam to precisely remove plaque without creating large defects, which reduces the need for extensive grafting. This method can also remove calcifications and is combined with a patch graft to correct curvature, offering a surgical option that preserves potency and improves penile curvature.36789

What data supports the effectiveness of CO2 Laser Therapy for Peyronie's Disease?

The research mentions laser therapy as one of the medical treatments available for Peyronie's disease, suggesting it might be valuable, especially in the early stages. However, no single treatment has been proven superior, and combination therapy is recommended until more studies are conducted.610111213

Are You a Good Fit for This Trial?

This trial is for healthy males aged 18 or older, diagnosed with Peyronie's Disease for at least a year and have stable disease. They must be in a stable relationship, able to read and understand English, and willing to sign consent forms. Men with penile curvature between 30º-90º are eligible.

Inclusion Criteria

You are willing to have vaginal intercourse with a female partner/spouse
Penile curvature of 30º-90º in the dorsal, lateral, or dorsal/lateral plane.
You have Peyronie's disease for at least 12 months with evidence of stable disease as determined by the investigator.

Published Research Related to This Trial

Collagenase clostridium histolyticum (CCH) therapy significantly improved penile curvature in men with Peyronie's disease over a 5-year period, with improvements of 20.9° in those with no calcification and similar results in those with stippled or interfering calcification.
No long-term safety issues were identified, indicating that CCH is a safe and effective nonsurgical treatment option for men with Peyronie's disease, even in cases of plaque calcification.
Long-term Curvature Deformity Characterization in Men Previously Treated With Collagenase Clostridium Histolyticum for Peyronie's Disease, Subgrouped by Penile Plaque Calcification.Goldstein, I., McLane, MP., Xiang, Q., et al.[2022]
In a study of 918 patients with Peyronie's disease, treatment with collagenase Clostridium histolyticum resulted in a significant improvement in penile curvature, reducing the average curvature from 48.2 degrees to 32.9 degrees, which is a 30.1% improvement.
The treatment was found to be safe, with only 9% of patients experiencing complications, and the number of treatment cycles was positively correlated with the degree of curvature improvement.

Collagenase clostridium histolyticum (CCH) is effective in treating ventral penile curvatures caused by Peyronie's Disease, with significant improvements observed in curvature after treatment, particularly for ventral (49% improvement) and lateral (38% improvement) curvatures compared to dorsal (25% improvement).
The treatment was found to have a similar safety profile across different curvature directions, with no urethral complications reported, indicating that CCH is a safe option for men with ventral Peyronie's Disease.
