About this study

Official title: Cilostazol-Aspirin Therapy Against Recurrent Stroke With Intracranial Artery Stenosis (CATHARSIS)

Multi-center, open-labelled randomized controlled trial, to study the effect of aspirin plus cilostazol and aspirin alone on the progression of intracranial arterial stenosis, in 200 chronic stroke patients with 50-99% stenosis, to be followed up for 2 years

Read the detailed description

Intracraial arterial stenosis (IAS) is more common in Asia, including Japanese, than in Cocasian. Also, stroke recurrence rate is high in patients with such lesions, despite medical treatment. Accoding to the result of WASID (N Engl J Med 2005;352:1305-16), warfarin is not recommended because of the concern of safety (higher risk of intracranial hemorrhage and death when compared with aspirin), wheras the efficacy of aspirin is not enough in symptomatic IAS patients. Under these conditions, we planned to conduct a nationwide multi-center, open labelled, randomized controlled trial to compare the effect of aspirin plus cilostazol (phosphodiestrase type 3 inhibitor) and aspirin alone on the progression of IAS in 200 IAS patients with ischemic stroke after 2 weeks to 6 months of onset. Patients are randomly allocated to either of two groups. Aspirin 100mg/day plus cilostazol 200 mg/day is given to the 100 patients in one group, and aspirin 100 mg/day alone is given to 100 patients in another group.

Follow-up period is at least two years. The primary endpoint is progression of IAS on MRA at two years after randomization. The secondary endpoints are cardiovascular events (ischemic stroke, myocardial infarct, and other vascular events), death, serious adverse events, new silent brain infarcts, and activity of daily life. The purpose of this study is to establish the best medical treatment in symptomatic IAS patients. This study will also provide important information for the future randomized controlled study to compare medical treatment alone and intravascular intervetnion (PTA and/or stenting) in these patients.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Asprin, Cilostazol in people with Cerebrovascular Disease, run by Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan at 1 site in Japan.

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 7 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 19 Dec 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 Japan. 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?

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?

Progression of intracranial arterial stenosis after two years. 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 19 Dec 2017.
