Efficacy & Safety of a 2nd Series of Low Intensity Shock Waves for ED on Partial Responders to First Treatment
A Phase 3 study testing Low Intensity Extracorporeal Shock waves (Cardiospec 1000) in people with Erectile Dysfunction, run by Rambam Health Care Campus at 1 site in Israel.
Trial summary
Low intensity shock waves (LISW) have been proven in animal studies to induce local growth of new blood vessels. The investigators hypothesized that LISW therapy could improve the symptoms of patients with erectile dysfunction resulting from a problem of blood supply who respond to oral therapy (PDE-5 inhibitors).

About this study
Official title: Efficacy and Safety of a Second Series of Low Intensity Extracorporeal Shock Wave Therapy (LI-ESWT) Treatment for Erectile Dysfunction Patients Who Were Partial Responders to the Initial Treatment.
Low intensity shock waves (LISW) have been proven in animal studies to induce local growth of new blood vessels. The investigators hypothesized that LISW therapy could improve the symptoms of patients with erectile dysfunction resulting from a problem of blood supply who respond to oral therapy (PDE-5 inhibitors). The current study will check the Efficacy and Safety of a Second Series of LISW Treatment for Erectile Dysfunction Patients Who Were Partial Responders to the Initial Treatment.
Read the detailed description
The patients will be selected out of the patients with Erectile Dysfunction who received Low intensity shock waves and Were Partial Responders to the treatment.
At the first meeting the patient will receive a full explanation of the study, the potential efficacy and risks. After that the patient will be asked to sign an informed consent form. The patient's general medical condition and any problems related to sexual dysfunction are already known from the previous study he was participating. Also the patient's sexual function is already known by sexual function questionnaires that were filled out in previous study. The criteria for inclusion and exclusion will be reviewed, as well as physical examination. Then shall the patient obtain reporting sexual encounter diaries (SEP) and will be asked to avoid using PDE5i's for a month (washout), if he did not do so of some reason after ending the previous study, then it would be the first visit (Visit 1). At visit 1 The patient will be questioning the sexual function questionnaires without PDE5i's and will pass examination performance Endothelial - FMD, the test takes about 10 minutes, it is not an invasive test (not involved in inserting an instrument or any medication) and is painless. The patient may be asked to also undergo Doppler ultrasound. At the end of visit 1 the patient will begin Series of 12 treatments, in which the subject will be treated twice a week for 3 weeks (6 treatments), then would be discontinuation of the study for 3 weeks, and at the end of this period will be treated twice a week for 3 weeks (6 treatments). Four weeks after the treatment series ends the patient will come for another visit and will be asked to fill in questionnaires and perform the FMD and/or Doppler ultrasound test again. The patient's ED condition will be followed up for a long term after the end of his participation in the study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Low Intensity Extracorporeal Shock waves (Cardiospec 1000) in people with Erectile Dysfunction, run by Rambam Health Care Campus at 1 site in Israel.
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 5 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 26 Jul 2012. 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 Israel. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yoram Vardi Vardi, Prof. MD (00972-4-8542819, yvardi@rambam.health.gov.il), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
IIEF-ED Domain score (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 26 Jul 2012.
