Study summary

The objective of this study is to evaluate the safety and efficacy of intraprostatic injection of Botox for the treatment of men diagnosed with chronic nonbacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Read the detailed description

This is a prospective open label study examining the efficacy and safety of intraprostatic Botox . Men with a clinical diagnosis of chronic nonbacterial prostatitis/CPPS will be treated with intraprostatic Botox™ and followed for 12 weeks (primary efficacy analyses), and 24 weeks (long term follow-up) for responders.

It is proposed that a total of 40 males will be enrolled. There will be seven (7) research clinic visits and two phone contacts: Visit 1 (screening), Visit 2 (baseline/treatment), Visit 3 (2-week safety evaluation - clinic contact), Visit 4 (4-week safety evaluation - phone contact), Visit 5 (6-week interim efficacy/safety), Visit 6 (12-week primary endpoint evaluation), Visit 7 (14-week clinic follow up), Visit 8 (16 week phone contact) and Visit 9 (24-week clinic close out).

Outcome measures include Chronic Prostatitis Symptom Index (CPSI 0-35), NRS pain (0-10), Global Response Assessment (GRA) at 12 weeks. Safety to be monitored during the study.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
