Study summary

Acute ischemic stroke is a major cause of disability and death. Intravenous thrombolytic therapy is an important treatment option when given within the appropriate time window. Recombinant human prourokinase (rhPro-UK) is a thrombolytic medication approved for the treatment of acute ischemic stroke within 4.5 hours after symptom onset in China.

This prospective, multicenter cohort registry study aims to evaluate the effectiveness and safety of intravenous rhPro-UK in patients with acute ischemic stroke treated within 4.5 hours of symptom onset. Approximately 3,000 patients from multiple centers will be enrolled and followed for 90 days. Clinical outcomes, bleeding events, adverse events, and functional recovery will be collected and analyzed to provide further evidence on the use of rhPro-UK in routine clinical practice.

Study population

Adults with acute ischemic stroke who receive intravenous recombinant human prourokinase treatment within 4.5 hours of symptom onset. Eligible participants are patients aged ≥18 years with a pre-stroke modified Rankin Scale (mRS) score of 0-1 who are considered suitable for intravenous thrombolysis with recombinant human prourokinase by the treating investigator.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adults aged ≥18 years, regardless of sex.
  • Pre-stroke modified Rankin Scale (mRS) score of 0-1.

  • Written obtained from the participant or legally authorized representative.

Exclusion criteria

Exclusion Criteria:

  • Known severe to recombinant human prourokinase.
  • Other severe neurological, psychiatric, or systemic diseases that may interfere with outcome assessment, adherence, or follow-up.

  • Unable to complete 90-day follow-up, poor compliance, or other conditions considered unsuitable for study participation by the investigator.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
