What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Recombinant Human Prourokinase for Injection (rhPro-UK)Drug

    Also called Aspirin, clopidogrel, anticoagulant

    Standard antiplatelet or anticoagulant treatment at the discretion of local investigators.

Study groups in NCT05507645
Study groupRoleWhat they receive
rhPro-UK (35mg)ExperimentalrhPro-UK: 35 mg (5 mg per vial, 7 vials in total) Dissolve 15mg (3 vials) of rhPro-UK in 10ml of saline and intravenous bolus within 3 minutes, and dissolve the remaining 20mg (4 vials) in 90ml of saline and intravenous drip within 30 minutes. (Note: after adding saline, overturn it gently once to twice, do not shake vigorously, so as to avoid foaming of the rhPro-UK solution and reduce the efficacy).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Recombinant Human Prourokinase for Injection (rhPro-UK) and standard medical treatment in people with Ischemic Stroke and Mild, run by Beijing Tiantan Hospital at 89 sites in China.

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 16 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 5 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 89 sites in China. 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?

The modified Rankin Scale score (mRS) ≤ 1 at 90 days (time frame: 90 days). 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 NCT05507645, which also lists 2 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 5 Sep 2024.
