Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

55 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Acute traumatic intracranial hemorrhage on either mono or dual antiplatelet therapy
  2. History of stroke, vascular stent or coronary or peripheral arterial disease as indication for antiplatelet *Restarting dual platelet therapy requires one of the following indications: 1) Acute myocardial infarction in the last year; 2) Coronary stent in the last year; 3) Non-cardioembolic stroke in the last 21 days (with switch to monotherapy at 21 days post stroke) 4) Peripheral arterial stent in the past month (with switch to monotherapy at one month post stent placement).

Exclusion Criteria:

  1. SDH >8 mm maximum width or any midline shift at any time point or more than one SDH
  2. Physician plan to start/restart anticoagulant therapy during trial period
  3. Abbreviated Injury Scale other than head >3
  4. Pregnancy
  5. Inability to understand need for adherence to study protocol
  6. Any active pathological bleeding (no acute blood on most recent CT)
  7. Hypersensitivity to drug or other label contraindication
  8. Any bleeding that the investigator deems unsafe to restart at 1 week post injury
  9. Inability to swallow

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: 1 week restart
Restart of mono or dual antiplatelet therapy one week post injury in TICrH patients
Other: Timing/1 week
Time of restart of antiplatelet therapy is one week after injury
Active Comparator: 3 week restart
Usual Care for restart of mono or dual antiplatelet therapy after TICrH at clinician's discretion
Other: Timing/3 weeks
Time of restart of antiplatelet therapy is left to treating clinician discretion

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
major bleeding
Time Frame: 60 days
Recurrent ICrH or other major bleeding defined by BARC3A
60 days
Major Vascular Occlusive events
Time Frame: Baseline (gambles performed pre-randomization)
Ischemic stroke; myocardial infarction; mesenteric ischemia; peripheral arterial occlusion; deep vein thrombosis; pulmonary embolism; and carotid, coronary, or peripheral arterial revascularization procedures. Major vascular events defined by the Antithrombotic Trialists' Collaboration

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2022

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
October 1, 2023

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
