About this study
Official title: A Randomized, Double-blind, Placebo-controlled, Parallel Group Trial of HMR1766 Assessing the Efficacy and Safety of 3 Doses of HMR1766 Versus Placebo With Cilostazol as a Calibrator, Administered for 26 Weeks in Patients With Peripheral Arterial Disease (PAD) Fontaine Stage II
The primary objective is to investigate in patients suffering from intermittent claudication due to Fontaine stage II Peripheral Arterial Disease (PAD) whether a 26-week treatment by HMR1766 on top of clopidogrel may result in an improvement of walking capacity, by comparing three doses of HMR1766 to placebo, and calibrating such effect versus cilostazol.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing ataciguat (HMR1766) and cilostazol in people with Intermittent Claudication, run by Sanofi at 7 sites in 7 countries.
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 7 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 17 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States, Austria, Canada, France, Poland and 2 more countries. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Primary efficacy endpoint: percent change in initial claudication distance (ICD) measured at the 26-week treadmill test, compared with ICD measured at baseline (time frame: 26 weeks). 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 17 May 2018; AzTrials last refreshed its copy on 8 Nov 2026.
