Efficacy and Safety of Minocycline in the Treatment of Intracerebral Hemorrhage

December 14, 2025 updated by: The First Hospital of Jilin University

Efficacy and Safety of Minocycline in the Treatment of Intracerebral Hemorrhage: a Multicenter, Randomized, Open-label, Blinded Endpoint Clinical Study

This study plans to enroll 1248 patients with supratentorial ICH within 24 hours of onset across multiple stroke centers. After randomization, the control group will only receive medical therapy. The experimental group, after randomization, will receive an initial dose of 200 mg of minocycline hydrochloride capsules in addition to medical ttherapy, followed by 100 mg orally every 12 hours for 7 days, resulting in a total of 14 administrations. Both groups will be followed for 180 days to evaluate the efficacy and safety of minocycline in the treatment of ICH.

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.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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
The proportion of patients with favorable functional outcomes, defined as mRS 0-2 at 180 days.
Time Frame: 180 days
Modified Rankin Scale (mRS) ranged from 0 to 6, a low value represents a better outcome.
180 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.

The NIHSS scores after 7 days of treatment.
Time Frame: 7 days
The NIHSS is an ordinal hierarchical scale to evaluate the severity of stroke by assessing a patient's performance. Scores range from 0 to 42, with higher scores indicating a more severe deficit.
