NCT03518983

Brief Summary

This is a double-blind, sham-controlled randomized, 2 parallel arms, clinical trial with a 12-month recruitment period. All patients will be PDE5I users/responders. After 1 month wash-out period, ED patients will be screened, in order to randomize 70 men with vasculogenic ED.Patients will be randomized in 2 groups (35 subjects in each group) to receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session), twice a week (total of 6 weeks) either at energy level 7 or at sham-control , without treatment interval. The IIEF-ED domain will be evaluated at Visit 1 and, consequently, at baseline and all follow up visits together with the SEP diaries.

Outcome Measures

Primary Outcomes (1)

  • The difference between the 2 groups in the percent of subjects who achieve clinically important difference (MCID) in the EF domain score of the IIEF

    MCID is defined according to baseline ED severity as:Improvement by 5 or more in the EF domain score of the IIEF for patients with moderate ED(EF scores 11-16) at baseline

    at 3 month follow up visit

Secondary Outcomes (3)

  • The difference between the 2 groups in the change of the EF domain score of the IIEF

    baseline and 3 month follow up visit.

  • Change in Sexual Encounter Profile Question 3 (SEP3) score

    baseline and 3 month follow up visit.

  • Number of patients with treatment related adverse events

    18 weeks

Study Arms (2)

Sham Group

SHAM COMPARATOR

The subjects of this group will receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session), twice a week (total of 6 weeks) by the sham probe.

Device: Dornier Aries2 device (sham probe)

Active Group

ACTIVE COMPARATOR

The subjects of this group will receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session), twice a week (total of 6 weeks) at energy level 7.

Device: Dornier Aries2 device

Interventions

The Dornier Aries2 device and will be used for the purpose of the study. LI-ESWT will be applied to the penile shaft and the 2 crura(two sites).

Active Group

The Dornier Aries2 device and will be used for the purpose of the study but the active probe will be replaced by an identical sham probe.

  • Presence of Erectile Dysfunction for at least 6 months.
  • At Screening, diagnosed as Vasculogenic erectile dysfunction based on sexual history
  • PDE5i users and report some or good response to PDE5i. Last reported PDE5i use must be within 30 days of Screening Visit.
  • Agree to suspend all ED therapy for the duration of the study.
  • Agree to attempt sexual intercourse at least 4 times during the last 4 weeks prior to Visit 2/Randomization, 1-month Follow Up and 3-month Follow-Up without being under the influence of alcohol or recreational drugs. Agree to document the outcome using the Sexual Encounter Profile (SEP) diary.
  • At Visit 2 (after PDE5i washout), SEP Q2, "Were you able to insert your penis into your partner's vagina?" answered "YES" 25% - 100% of the time.
  • At Visit 2, SEP Q3, "Did your erection last long enough for you to have successful intercourse?" answered "YES" 0% - 50% of the time.
  • At Visit 2, IIEF-EF score 11 - 16.
  • \. At Visit 2, IIEF Q3 score 2 - 5. 14. At Visit 2, IIEF Q4 score 1 - 3.

You may not qualify if:

  • Previous major pelvic surgery or pelvic trauma that could impact erectile function, such as radical prostatectomy, radical cystectomy, rectal surgery. Patients with previous TURP surgery without sequelae of iatrogenic ED, may be included.
  • Previous penile surgery of any kind except circumcision and condyloma removal, such as penile lengthening, penile cancer surgery, penile plication, grafting.
  • Previous history of priapism or penile fracture
  • Previous radiation therapy to pelvis.
  • Abnormal serum testosterone level defined as a value lower than 300 ng/dL (indicative of untreated hypogonadism), or greater than 1197 ng/dL.
  • Current or previous hormone usage, other than prescribed testosterone, clomiphene or thyroid medication. Subjects with prior or current use of hormonal treatment for prostate cancer are also excluded.
