Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study aims to explore the feasibility, safety and effectiveness of two different extracorporeal shock wave therapy (ESWT) protocols for patients receiving nerve-sparing radical prostatectomy (RP).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an open-label, randomized, 2-parallel-arm trial (n=94). All patients will receive (A) sham (n=47) or (B) active ESWT (n=47) twice/week for 6 weeks (12 sessions total). Concurrently, all patients will receive daily tadalafil 5mg for 24 weeks. Patients will then undergo a 4 week washout period without erectogenic aids, and return for a 28-week evaluation. Subsequently, patients requiring further erectogenic aids after 28 weeks will be offered intracavernosal injections (ICI) of prostaglandin E1 (PGE1).

Random assignment will be performed by computer program (eg. randomizer.org), in a design that obtains equal sample size per group.

All patients will be followed for a period of 24 months post-RP. Follow-up protocol includes evaluation of the IIEF, EHS, GAQ, ICI usage and tolerability, stretched flaccid penile length, urinary incontinence, and oncologic status.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sham ESWT + 5mg Tadalafil

Patients will receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session), using a sham applicator which is highly similar to the active applicator except that the sham applicator does not emit shockwaves, twice a week (total of 6 weeks) without treatment interval. Patients will receive Tadalafil 5mg for 24 weeks daily beginning the day of removal of the urinary catheter.

Group Type SHAM_COMPARATOR

Dornier Aries 2 (with sham applicator)

Intervention Type DEVICE

Sham ESWT - No shockwave administered

Active ESWT + 5mg Tadalafil

Patients will receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session), twice a week (total of 6 weeks). Patients will receive Tadalafil 5mg for 24 weeks daily beginning the day of removal of the urinary catheter.

Group Type ACTIVE_COMPARATOR

Dornier Aries 2 (with active applicator)

Intervention Type DEVICE

Active ESWT: 5000 shockwaves per session. 2 ESWT sessions per week, 12 sessions in total.
