• 1 other identifier: BTHDMF
• Study Type: interventional
• Target: 60
• Locations: 1 country
• Sites: 1

Brief Summary

This study was designed to identify whether there is a measurable reduction in inflammation in walls of intracranial aneurysms with oral dimethyl fumarate.

Conditions

Intracranial Aneurysm; Aneurysm, Brain; Inflammation Vascular

Keywords

Dimethyl Fumarate; High resolution magnetic resonance

Outcome Measures

Primary Outcomes (1)

• Change of aneurysm wall inflammation as measured by HR-VW-MRI.

  At the end of 6 months, the changes of Wall enhancement index (WEI) and wall enhancement volume rate (WEVR) on HR-VW-MRI will be quantitatively compared between the DMF group and placebo group.

  6 months

Secondary Outcomes (2)

• Change of aneurysmal morphology parameter

  6 months

• Change of inflammatory markers in patients

  6 months

Study Arms (2)

Dimethyl fumarate

EXPERIMENTAL

dimethyl fumarate enteric capsule (the initial dose is 120 mg twice a day, and after 7 days, the dose will be increased to the maintenance dose of 240 mg twice a day, for 6 months)

Drug: Dimethyl fumarate

Placebo

PLACEBO COMPARATOR

placebo with the same appearance (color, taste, size, shape)

Drug: Placebo

Interventions

Dimethyl fumarate DRUG

dimethyl fumarate enteric capsule (the initial dose is 120 mg twice a day, and after 7 days, the dose will be increased to the maintenance dose of 240 mg twice a day, for 6 months), 30 patients for this arm.

Dimethyl fumarate

Placebo DRUG

placebo with the same appearance (color, taste, size, shape), 30 patients for this arm.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male or female aged ≥18 years.
• Unruptured IA of ≥3mm identified on imaging (CT, MRI or digital subtraction angiography).
• Aneurysm wall enhancement identified by HR-VWI before treatment.
• Ability to understand the objective of the trial with provision of written informed consent.

You may not qualify if:

• MRI contraindications (metallic implant, contrast allergy, claustrophobia, etc).
• Planned treatment of the aneurysm within 6 months.
• Current treatment with drugs that might have an anti-inflammatory effect (aspirin, statins, immunosuppressive drugs, angiotensin converting enzyme, etc.).
• Severely impaired liver or renal function.
• Retreatment of recurrent aneurysm.
• Pregnant or lactating women.
• Malignant diseases (liver disease, kidney disease, congestive heart failure, malignant tumours, etc.).
• Poor compliance with treatment or follow--up (patients who refuse to take medication as prescribed, patients who decline imaging follow--up or blood test, etc).

Study Design

• Study Type: interventional
• Phase: phase 4
• Allocation: RANDOMIZED
• Masking: QUADRUPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: The patients with intracranial aneurysms will be numbered and randomly divided into two groups, 30 patients in each group, and seal them. Through blind method, one group will be given dimethyl fumarate enteric capsule (the initial dose is 120 mg twice a day, and after 7 days, the dose will be increased to the maintenance dose of 240 mg twice a day, for 6 months). The other group took placebo with the same appearance (color, taste, size, shape) as the test drug.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: SPONSOR

Model Details: A total of 60 patients will be enrolled in this study. Randomly divide the patients into experimental group and placebo group according to 1:1 ratio.
