February 17, 2019 updated by: Ying Gao, Dongzhimen Hospital, Beijing

Effectiveness and Neural Mechanism of Naoan Dripping Pills for Migraine: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

This is a randomized, double-blind, placebo-controlled clinical trial. Its main purpose is to investigate the effects and neural mechanism of Naoan dripping pills on migraine patients by utilizing fMRI and DTI method, as well as headache evaluation measures such as responder rate, headache duration, PRO scale, etc.

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

Naoan dripping pills, which is a Chinese patent medicine proved effectively in treating migraine on clinic, but its neural mechanism remains unknown. This study is expected to validate the effectiveness and explore its neural mechanism by fMRI and DTI so as to provide evidence for physicians to promote the appropriate use of Naoan dripping pills treatment for migraine patients. Patients will be randomly assigned to either Naoan dripping pills group or placebo group, they will receive Naoan dripping pills/Placebo treatment for 12 weeks. Clinical evaluation will be performed at baseline, every 4 weeks during treatment and the follow-up week(16 weeks) . MRI scans are performed at baseline, and 12 weeks later. Responder rate (defined as the percentage of subjects in a treatment group with 50 % or greater reduction in attack frequency during treatment compared with the baseline period) and fMRI and DTI imaging changes after treatment are defined as primary outcome. In addition, 10 healthy controls will also undergo MRI scanning at baseline to determine abnormal brain activity and structure in migraine patients.

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.
