Antiplatelet Secondary Prevention International Randomised Trial After INtracerebral HaemorrhaGe (ASPIRING)-Pilot Phase

March 22, 2025 updated by: The George Institute for Global Health, China

An Investigator Initiated and Conducted, Prospective, Multicentre, Randomised Outcome-blinded Pilot Study of Antiplatelet Therapy in Patients with a History of Stroke Due to Intracerebral Haemorrhage

ASPIRING is an investigator-led, multicentre, prospective, randomised, open-label, blind outcome (PROBE), parallel group, clinical trial. The pilot phase will explore the feasibility of conducting a trial of starting antiplatelet monotherapy versus avoiding antiplatelet therapy for reducing all serious vascular events for adults surviving symptomatic stroke due to spontaneous intracerebral haemorrhage (ICH). The pilot phase will involve ~120 patients at ~30 hospitals in China, Australia and New Zealand.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The participant eligibility criteria specifically identify adults with history of symptomatic spontaneous ICH. Randomisation occurs if a participant and their doctor are uncertain about whether to start or avoid antiplatelet monotherapy at least 24 hours after ICH symptom onset. The intervention is a pragmatic policy of starting antiplatelet monotherapy (one antiplatelet drug available in local standard clinical practice, chosen by patient's physician pre-randomisation). The control group adopts a policy of avoiding antiplatelet therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  2. Symptomatic stroke due to spontaneous (non-traumatic) ICH.
  3. Patient is at least 24 hours after ICH symptom onset.
  4. Patient and their doctor are both uncertain about whether to start or avoid antiplatelet monotherapy.
  5. Consent to randomisation from the patient (or personal / legal / professional representative if the patient does not have mental capacity).

Exclusion Criteria:

  1. ICH due to head injury, in the opinion of the investigator.
  2. ICH due to haemorrhagic transformation of an ischaemic stroke, in the opinion of the investigator.
  3. Patient is already taking antiplatelet therapy, or full dose anticoagulant therapy, after ICH.
  4. Patient is pregnant, breastfeeding, or of childbearing age and not taking contraception.
  5. Patient and carer unable to understand spoken or written local language.
