About this study

Official title: The Efficacy of Botulinum Toxin Type a in Treating Peyronie's Disease

Peyronie's disease is a condition in which a plaque, or hard lump, forms on the penis. It causes hardened tissue, pain, and an abnormal bending in the penis. These symptoms are more severe during an erection. Significant bending of the penis can result in pain, poor erections, and an inability to engage in sexual intercourse.

This disease affects about 3% of the male population. The average age of onset of this disease is 57 years old. The cause of the disease is unknown. However, many believe that it may be due to trauma to the penis (such as injury or extremely vigorous sexual activity).

Read the detailed description

Treatments for this disease have been limited and often unsuccessful. The goal of treatment is to reduce pain and maintain sexual function. Oral medicines that prevent plaque formation and promote plaque breakdown have not been effective. Many patients with the disease will require injections of medicines directly into the plaque. These injections have been used for over 50 years in the treatment of major Peyronie's disease. The disease often resolves on its own without treatment. Surgery may be performed to remove hardened tissue in the penis. However, surgery is not done during the first 12 months of the disease.

There are 2 phases of the disease: the active phase and the inactive phase. The active phase usually occurs during the first 12 months of the disease. The stabilization of the plaque is known as the inactive phase. We are inviting men with stable disease to take part in this study which will test BOTOX® versus a placebo (a placebo contains no medicine).

This will be a randomized, placebo-controlled, cross-over, single-center trial. The placebo group has the option to cross over to the treatment arm (ARM 1) of the study at the end of their 16 weeks of placebo arm (ARM 2). Study drug is Botulinum toxin type A (BOTOX®). Subjects who meet the inclusion criteria for the study will be randomized to either the treatment or placebo arm.

  • Treatment: Injection solution will consist of 100 units of BOTOX® in 10 cc of preservative free normal saline, or
  • Placebo: Injection solution will consist of 10 cc preservative free normal saline.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Average Percent Change of Penile Curvature in Degrees

    Measured by a protractor from pictures taken at baseline (pre-treatment screening visit) and end of treatment at week 16

    *Crossover subjects were added to Experimental Group for analysis*

    Negative value equates to a reduction in curvature Positive value equates to an increase in curvature

    Measured: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16

Secondary outcomes (4)
  1. Change in Penile Blood Flow for Peak Systolic Velocity (PSV) and End-diastolic Velocity (EDV)

    Results of penile doppler ultrasound from baseline/screening visit to end of treatment at week 16 will be compared.

    peak systolic velocity (PSV) and end-diastolic velocity (EDV) are assessed here.

    Change is calculated as week 16 values - screening visit values

    Negative values are a decrease in velocity Positive values are an increase in velocity

    Measured: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16

  2. Change in Penile Blood Flow for Diameter

    Results of penile doppler ultrasound from the baseline/screening visit to end of treatment at week 16 will be compared.

    Diameter is assessed here.

    Change is calculated as week 16 values - screening visit values

    Negative values are a decrease in diameter Positive values are an increase in diameter

    Measured: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16

  3. Change in Penile Plaque Size

    Results of ultrasound at baseline/screening visit to end of treatment at week 16 will be compared.

    *Crossover subjects were added to Experimental Group for analysis*

    Change is calculated as week 16 values values minus screening visit values

    Increase in value equates to increased plaque size Decrease in value equates to decreased plaque size

    Measured: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16

  4. Changes in International Index of Erectile Function Scores (IIEF)

    Subject's average scores on IIEF at baseline/screening visit to end of treatment at week 16 are compared

    The subscale measures self-reported erectile function. Maximum score is 30, Minimum is 0. A score of 0 is the absolute best outcome. A score of 30 is the absolute worst outcome. Erectile Function score is a summation of questions 1,2,3,4, and 15. This study is assessing their erectile function and not the other subscales.

    The other subscale scores are :

    1. Orgasmic Function (Questions 9, 10); Maximum score = 10, Minimum score = 0
    2. Sexual Desire (Questions 11, 12); Maximum score = 10, Minimum score = 0
    3. Intercourse Satisfaction (Questions 6, 7, 8); Maximum score = 15, Minimum score = 0
    4. Overall Satisfaction (Question 13, 14): Maximum score = 10, Minimum score = 0

    Subscales are not combined to make a total composite score.

    *Crossover subjects were added to Experimental Group for analysis*

    Measured: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16

A Phase 2 study testing 100 units of Botulinum Toxin Type A, Preservative free normal saline and 100 units Botulinum Toxin A in people with Peyronie's Disease, run by Mohit Khera at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Feb 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Average Percent Change of Penile Curvature in Degrees (time frame: Baseline (Pre-Treatment Screening Visit) to end of treatment at week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00812838, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2024.
