About this study

Official title: The Field Administration of Stroke Therapy-Blood Pressure Lowering Pilot Trial

This is an open, pilot, dose-escalation study of glyceryl trinitrate (GTN, Nitroglycerin) administered by paramedics in the field within 2 hours of symptom onset to 45 severely hypertensive stroke patients. The primary objective of the study is to evaluate the feasibility, safety, and physiologic efficacy of field-initiated glyceryl trinitrate in achieving modest reduction of blood pressure. Patients with acute stroke will be identified in the field by paramedics who have received training in basic and advanced cardiac life support, stroke recognition, and specific procedures relevant to the proposed study. Physician-investigators will obtain informed consent for each subject for study entry after cellular phone contact with paramedics. Paramedics will initiate antihypertensive treatment by applying transdermal GTN patch in the first two dose-tiers, and administering a single sublingual GTN metered spray followed by application of the transdermal system in the last dose tier. The sites involved in the study will be emergency medical services rescue ambulances and 8 receiving Stroke Center hospitals in Orange County, California, USA.

Read the detailed description

The central aim of this phase 2a study is to identify a regimen of paramedic initiated glyceryl trinitrate antihypertensive therapy in acute stroke patients that is safe, is technically effective in modestly lowering blood pressure, and is optimal to advance to a pivotal trial. The study design is an open-label dose escalation study with three dose tiers,. It is anticipated that the trial will identify the most promising prehospital GTN regimen to advance to a pivotal, placebo-controlled, phase 3 trial.

Primary Hypothesis: Prehospital glyceryl trinitrate treatment reduces severely hypertensive blood pressure elevation by ED arrival.

The primary study endpoint to test this hypothesis will be the mean change in SBP from pre-treatment to ED arrival.

Secondary Hypotheses:

  1. Prehospital glyceryl trinitrate treatment reduces severely hypertensive blood pressure elevation at early post-arrival timepoints and increases the proportion of patients with target blood pressure at ED arrival and early post-arrival timepoints. The secondary study endpoints analyzed to test these hypotheses will be: 1) mean change in SBP from pre-treatment to 30 minutes after ED arrival and 60 minutes after ED arrival; and 2) the proportion of patients with SBP < 180 mm Hg at ED arrival, 30, and 60 minutes after arrival.
  2. Prehospital initiation of glyceryl trinitrate in the first 2 hours for severely hypertensive patients with stroke is feasible and safe.

Safety of GTN in the first 2 hours for severely hypertensive stroke patients will be assessed by analysis of serious adverse events, neurologic change, and mortality. We hypothesize that initiation of treatment of the patients in the field will be associated with a favorable side effect profile and without severe blood pressure lowering to les than 120 mm Hg systolic.

Successful completion of the study will demonstrate feasibility to recruit hypertensive stroke participants and initiate GTN therapy in the field by paramedics.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participants With Systolic Blood Pressure Change of 8mmHg or More

    The mean change in blood pressure was measured in the Emergency Department approximately 15 minutes after application of the treatment

    Measured: Baseline, 15 minutes after treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Glycerly Trinitrate in people with Intracerebral Hemorrhage and Ischemic Stroke, run by University of California, Los Angeles at 2 sites in United States.

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 9 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: stopped early, as of the sponsor's last update on 29 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Participants With Systolic Blood Pressure Change of 8mmHg or More (time frame: Baseline, 15 minutes after treatment). 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 29 Oct 2020.
