A Single-Arm, Dose Escalation of an Intraurethral Alprostadil Paste for Erectile Dysfunction
Phase 2 Clinical Trial of ST-04 Intraurethral Paste for Erectile Dysfunction
This is a single arm dose escalation trial of a mucoadhesive intraurethral polymer suspension of alprostadil (ST-04) and will investigate the efficacy of 3 dose levels of ST-04 in adult males with a clinical diagnosis of Erectile Dysfunction (ED). This study aims to determine if ST-04, with or without sildenafil, will improve erectile function (EF) compared to baseline.
Participants in this study will receive ST-04, a new formulation containing the vasodilator, alprostadil which is known to be an effective drug in treating erectile dysfunction. ST-04 will be dispersed along the urethra, forming a hydrogel which adheres to the lining of the urethra with the goal of penile tumescence and erection. Participants may receive up to 3 dose level escalations of ST-04 over a 12-week period, for a total of up to 11 administrations of ST-04. Dose escalation may also be done with and without sildenafil.

측정값 설명 |
기간 |
|---|---|---|
|
Change from Baseline in the Erectile Function Domain of the IIEF Questionnaire
기간: From baseline to 1 month after start of the last dose level (Week 4, 8, 12 respectively)
|
The IIEF is a validated questionnaire assessing erectile function, with total scores ranging from 5 to 25; higher scores indicate better erectile function
|
From baseline to 1 month after start of the last dose level (Week 4, 8, 12 respectively)
|

측정값 설명 |
기간 |
|---|---|---|
|
Change from Baseline in the Erectile Hardness Scale (EHS)
기간: From baseline to the end of treatment at week 4, 8 or 12 respectively
|
The EHS is a self-reported assessment of penile hardness on a scale of 0 (no engorgement) to 4 (complete rigidity).
|
From baseline to the end of treatment at week 4, 8 or 12 respectively
|
|
Change from Baseline in the Sexual Encounter Profile (SEP)
기간: From baseline to the end of treatment at week 4, 8 or 12 respectively
|
SEP is a log diary completed after each sexual attempt, providing information as to whether the erection was hard enough to penetrate (SEP 2), or whether it was maintained for completion (SEP 3).
|
From baseline to the end of treatment at week 4, 8 or 12 respectively
|
|
Percentage of Uses per Participant of ST-04 which Led to the Onset of Erection within up to 30 minutes of Application per Number of Intercourse Attempts
기간: From baseline to the end of treatment at week 4, 8 or 12 respectively
|
Percentage of participants using ST-04 that could achieve an erection and/or penetrative intercourse within 30 minutes of application per number of intercourse attempts.
|
From baseline to the end of treatment at week 4, 8 or 12 respectively
|
|
Incidence and Severity of Adverse events
기간: From baseline to the end of treatment at week 4, 8 or 12 respectively
|
Adverse events will be recorded at each follow-up visit and classified by type, severity, and relationship to the intervention.
|
From baseline to the end of treatment at week 4, 8 or 12 respectively
