About this study
The investigators are doing this research to evaluate the efficacy and safety of topical MED3000 therapy in men with persistent erectile dysfunction 1.5 to 4 years following radical prostatectomy surgery.
Read the detailed description
MED3000 is a topical gel that has been developed to treat patients with erectile dysfunction. The investigators postulate that on demand treatment with MED3000 can improve on-demand erectile function among men status-post radical prostatectomy, allowing for some endogenous cavernosal nerve function recovery for 1.5 to 4 years post-surgery among men with normal baseline pre-surgical erectile function.
- Being tested
- MED3000 topical gel
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MED3000 topical gelDevice
Topical gel that has been shown to improve erectile dysfunction when used as needed.
| Study group | Role | What they receive |
|---|---|---|
| MED3000 topical gel treatment | Experimental | All qualified enrolled patients will receive treatment with MED3000 topical gel on demand through the 12-week follow-up visits. Receives: Device: MED3000 topical gel |
What is being measured
The primary outcome is the main question the study is designed to answer.
Whether the Erectile Function Domain of the International Index of Erectile Function Mean Change From Baseline Met or Exceeded the Minimally Clinically Important Difference (MCID) of 4
To investigate the effect of MED3000 topical gel for treatment of erectile dysfunction after nerve sparing prostatectomy (based on Erectile Function domain of the International Index of Erectile Function) (units on a scale) and whether it met MCID criteria of change of mean 4 [IIEF EF minimum score is 0, maximum score is 75, with higher scores representing improved erectile function); units on a scale
Measured: 12 weeks
Secondary outcomes (3)
Efficacy of MED3000 Topical Gel (Self-Esteem and Relationship Questionnaire)
The efficacy of MED3000 in patients at weeks 4, 8 and 12 using:
The change from baseline in Self-Esteem and Relationship (SEAR) questionnaire for men (units on a scale) [SEAR minimum score is 0, maximum score is 70, with higher scores representing improved outcomes); units on a scale
Measured: 12 weeks
Change From Baseline in All Domains of the IIEF.
The efficacy of MED3000 in patients at weeks 4, 8 and 12 (units on a scale). To investigate the effect of MED3000 topical gel for treatment of erectile dysfunction after nerve sparing prostatectomy (based on Erectile Function domain of the International Index of Erectile Function) (units on a scale) and whether it changed over time [IIEF EF minimum score is 0, maximum score is 75, with higher scores representing improved erectile function]; units on a scale
Measured: 12 weeks
Adverse Events of MED3000 Topical Gel
Treatment-related adverse events in male patients and female partners occurring during treatment with MED3000.
