Linear Piezoelectric Low Intensity Shockwave Treatment (LI-SWT) for the Treatment of Erectile Dysfunction in PDE5i Non Responder
Linear Piezoelectric Low Intensity Shockwave Treatment (LI-SWT) for the Treatment of Erectile Dysfunction in PDE5i Non Responder: A Randomized-Controlled Trial
The goal of this clinical trial is to assess the efficacy and safety of linear piezoelectric Li-SWT for erectile dysfunction patients who have poor treatment respond from PDE5i oral treatment. Participants will be randomised to either receive 4 cycles, once per week, of Li-SWT treatment on the penis or the Sham group, where the treatment appears to be identical but the shockwave machine is deactivated. Investigators will compare the before and after treatment erectile function using the IIEF questionnaire of the two groups 1 month after treatment to assess the treatment outcome. After that, the Sham group patient would be offered to receive compensatory Li-SWT treatment and their post treatment response will be assessed.
All the patients completing the Li-SWT treatment will be followed up at 6 and 12 months to assess the efficacy and adverse events.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Proportion of men with improvement in International Index of Erectile Function (IIEF) score at 1 month after traetment
Délai: 1 month after Sham/LiSWT
|
Total scores range from 5 to 25, where higher scores indicate better erectile function/lower severity of erectile dysfunction.
This outcome measure reports the proportion of participants achieving an improvement in IIEF score compared to baseline.

Proportion of men meeting the Minimal Clinically Important Difference (MCID) in the International Index of Erectile Function (IIEF) score
Délai: 1 month
|
The International Index of Erectile Function (IIEF) is a self-administered questionnaire used to assess erectile function.Total scores range from 5 to 25, where higher scores indicate better erectile function/lower severity of erectile dysfunction.
This outcome measure reports the proportion of participants achieving a minimal clinically important difference (MCID) in the IIEF-5 score compared to baseline.

|
Proportion of men meeting the Minimal Clinically Important Difference (MCID) in the International Index of Erectile Function - Erectile Function (IIEF-EF) domain score at 6 and 12 months after treatment
Délai: 6 and 12 months after treatment
|
IIEF is a self-administered questionnaire used to assess erectile function.
Total scores range from 5 to 25, where higher scores indicate better erectile function/lower severity of erectile dysfunction.
This outcome measure reports the proportion of participants achieving a minimal clinically important difference (MCID) in the IIEF-5 score compared to baseline.

6 and 12 months after treatment
|
|
Erectile hardness score (EHS) at 1,6, 12 months after treatment
Délai: 1, 6, 12 months after LiSWT treatment
|
vertical score assessing penile hardness on a 4-point single-item scale ranging from 1 to 4, where 1 indicates "penis is larger, but not hard" and 4 indicates "penis is completely hard and fully rigid."
Higher scores indicate better erectile function/rigidity.
|
1, 6, 12 months after LiSWT treatment

|
Side effects and safety profile
Délai: From initiation of first Sham/LiSWT treatment until 12 months after the last LiSWT treatment
|
e.g.
tolerability, pain using the visual analogue scale, bleeding, bruising, penile plaque, penile deformity Safety and tolerability will be evaluated by recording the incidence, severity, and type of all treatment-related adverse events.
Pain will be assessed using a Visual Analogue Scale (VAS), a single-item numeric scale ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicate greater pain intensity.
Specific adverse events evaluated include penile pain, bleeding, bruising, formation of penile plaque, and penile deformity.

From initiation of first Sham/LiSWT treatment until 12 months after the last LiSWT treatment
