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

Prior to the drug:

If you decide to take part in this study, you will have a brief interview about your medical history and any medications you are taking. You will have a medical and neurological examination, CT scan and/or an angiogram to look at the blood vessel and blood supply going to the brain, and blood samples drawn for a complete blood count, chemistry analysis and cardiac enzymes (to assess any recent damage to your heart). You will have a surgery or an image guided procedure to close your aneurysm.

Additionally, during the course of the study you may be asked to have a computerized tomography (CT scan) or magnetic resonance imaging (MRI) if there is a necessity. These tests will reveal areas that might have been damaged in your brain.

Drug:

If the tests show that you qualify as a candidate for this study, you will be randomly assigned (like a flip of a coin) to have either the minocycline drug or a dummy drug that looks the same but does not have the drug in it. For the first 7 days, the drug will be given as an injection two times a day and after that for 14 days once a day by mouth. Rest of the care will be standard like in any aneurysm patient. We study the status of your blood vessel surrounding the brain with ultrasound daily to see if they have any narrowing. If the doctors find any narrowing, you will be treated to relive the narrowing. If you are discharged home at any point in the 21 days, you will be switch the oral drug and given the required drugs with instructions.

Follow up:

Before you are discharged from the hospital and at 7, 21, 30 and 90 days after the start of the drug, the following evaluations will be performed: a complete physical and neurological examinations.

As part of this study, you are required to return to the hospital or to your physician at one (1), seven (7), twenty-one (21), thirty (30), ninety (90) days after stroke onset. You will have a physical exam, a complete neurological exam. Additionally, you will be asked questions about any health problems or hospitalizations you have had since you were discharged from the hospital.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

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
adverse event
Time Frame: 21 days

The primary objective of the study is to evaluate the effectiveness of minocycline in improving outcomes for patients after aneurysmal SAH.

To determine the safety of minocycline 200mg/day for 21 days in the treatment arm after aneurysmal subarachnoid hemorrhage.
21 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
comparative stroke scale
Time Frame: 3 months

To demonstrate a significant difference in outcome at 3 months as measured by NIHSS, mRS, BI and GOS in the minocycline treatment group when compared to the placebo arm.

To determine any significant differences in vasospasm rates, duration of vasospasm, interventions for vasospasm, vasospasm related infarcts and delayed ischemic deficits between minocycline and placebo arms

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.
