Brief 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).

Condition or disease Intervention/treatment Phase
Prostatitis Chronic Pain Syndrome Drug: Botox Phase 1

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.
