About this study
Official title: Low Intensity Extracorporeal Shock Wave Treatment (LI-ESWT) for Erectile Dysfunction (ED): Comparison of 6 Sessions Once a Week vs 12 Sessions Twice Per Week
The present study aims to identify and compare the efficacy and safety of two different session frequency protocols (once vs twice per week) of low intensity extracorporeal shockwave treatment (LI-ESWT) using Aries ED device, in men with mild-moderate and severe vasculogenic ED, who have previously responded to oral PDE5-Is
Read the detailed description
This is a randomized, 2 parallel arms, clinical trial. All patients will be PDE5I users/responders. After 1 month wash-out period, ED patients will be screened, in order to randomized 42 men with vasculogenic ED who had International Index of Erectile Function ED (IIEF-ED) domain scores between 6-25 and abnormal penile triplex-based hemodynamic parameters (peak flow velocity <35cm/sec). Then the 42 pts will be randomized to receive either one or two shockwave treatment sessions per week, without treatment interval. Every week all subjects may have at least one attempt for intercourse. All patients will complete 6 weeks of treatment.
Study visits and duration
Visit 1 (day 0): the basic work-up will take place, including medical and sexual history, as well as necessary lab tests, if needed. One month wash-out period will follow. During this period, all subjects will be asked to avoid any drug related to ED (PDE5i) and have at least 2-4 attempts for intercourse. Furthermore, patients will undergo triplex ultrasonography, unless they have already done so in the last 6 months. all patients will complete the IIEF-ED domain and will be randomized (1:1) to one of the two parallel study groups, using an online program. Groups A will receive treatment once per week for 6 weeks (6 sessions totally), and Groups B will receive treatment two times per week for 6 weeks (12 sessions totally). PDE5i use is prohibited throughout the study.
Treatment Visits: Patients will receive LI-ESWT , according to the study protocol.Interval between 2 treatments will be 7+2days for Group A and 3+1 day for Group B.At visit 6 and 12 a penile ultrasonography will be conducted in order to check for potential adverse events related to the treatment.
Follow-up visits 1 - 3 (4, 12 and 24 weeks post treatment): Patients will complete the IIEF-ED questionnaire and return the completed SEP diaries for the last 4 weeks prior to every visit. Visit data will also be recorded (protocol compliance, adverse events). At Week 12, triplex will be performed by the standard protocol. For Week 4 there is a + 3 days visit window, whereas for Weeks 12 and 24 there is a + 2 weeks visit window.

Dornier Aries- ED deviceDevice
The Dornier Aries-ED device will be used for the purpose of the study. LI-ESWT will be applied to the penile shaft 3 areas, and the 2 crura (two sites).
| Study group | Role | What they receive |
|---|---|---|
| Group A | Active comparator | Patients will receive one session of low intensity extracorporeal shock wave treatment (LI-ESWT) per week for 6 weeks (6 sessions totally). Receives: Device: Dornier Aries- ED device |

What is being measured
The primary outcome is the main question the study is designed to answer.
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 2 or more in the EF domain score of the IIEF for patients with mild ED ( EF scores 17-25) at baseline.
- Improvement by 5 or more in the EF domain score of the IIEF for patients with moderate ED(EF scores 11-16) at baseline
- Improvement by 7 or more in the EF domain score of the IIEF for patients with severe ED (EF scores 0-10) at baseline
Measured: at 6 month follow up visit
Secondary outcomes (4)
Change in the EF domain score of the IIEF
EF domain of the IIEF questionnaire will be completed
Measured: baseline and 6 month follow up visit.
Change in Sexual Encounter Profile Question 3 (SEP3) score
The percent of subjects who answer ''YES'' in question 3 of SEP questionnaire will be reported
Measured: baseline and 6 month follow up visit.
Change in mean peak systolic velocity (PSV)
Mean peak systolic velocity will be measured by penile triplex ultrasonography by the same investigator.
Measured: baseline and 3 month follow up visit
Number of patients with treatment related adverse events
Potential treatment related adverse events after the first LI-ESWT session and during the 6 month follow up period will be reported
Measured: 30 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Dornier Aries- ED device in people with Erectile Dysfunction, run by Institute for the Study of Urological Diseases, Greece at 1 site in Greece.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The percent of subjects who achieve clinically important difference (MCID) in the EF domain score of the IIEF (time frame: at 6 month follow up visit). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03089307, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2017.
