Outcomes

Primary Outcome Measures

The Change of Migraine Days
The change of migraine days per 4 weeks during the 12-week treatment period compared with baseline. Baseline refers to the frequency of migraine attacks within the 28 days prior to randomization (baseline period, i.e., D-28 to D-1). Headache data were captured through an electronic diary.

Secondary Outcome Measures

The Change of Headache Attack Frequency
The change of headache attack frequency per 4 weeks during the 12-week treatment period compared with baseline. Headache data were captured through an electronic diary.
The Change of Moderate / Severe Headache Days
The change of days with moderate / severe headache per 4 weeks during the 12-week treatment period compared with baseline.
The Responder Rate of at Least 50%, 75% and 100% Reduction of Migraine Days
The Responder Rate of at Least 50%, 75% and 100% Reduction of Migraine Days is compared with the baseline per 4 weeks during the 12-week treatment period. Headache data were captured through an electronic diary.
The Dose of Acute Medication Use
Variation in the dose of medications for the acute migraine per 4 weeks during the 12-week treatment period compared with baseline. The allowed medications to treat an acute migraine include the following categories of drugs: triptans, ergots, opioids, analgesics (including acetaminophen), NSAIDs, and antiemetics. Data were captured through an electronic diary.
The Change of Frequency of Medications Use
The change of frequency of medications for the acute migraine per 4 weeks during the 12-week treatment period compared with baseline. The allowed medications include the following categories of drugs: triptans, ergots, opioids, analgesics (including acetaminophen), NSAIDs, and antiemetics. Data were captured through an electronic diary.
The Change of Peak Headache Pain Intensity
The change of peak headache pain intensity per 4 weeks during the 12-week treatment period compared with baseline. Subjects should record the maximum intensity of daily headaches and any medication used. An 11-point digital rating scale can be used instead of or in conjunction with a 4-level classified rating scale. The 11-point visual analogue scale (VAS) has 10 scales, with a "0" end and a "10" end at both ends, where 0 means no pain, and 10 means the most severe pain that is unbearable.4-level classified rating scale was used to evaluate the headache intensity of each migraine day--painless, mild, moderate, or severe. Headache data were captured through an electronic diary.
The Change of Average Headache Intensity
The change of average headache intensity per 4 weeks during the 12-week treatment period compared with baseline. Four-point rating scale was used to evaluate the headache intensity of each migraine day--painless, mild, moderate, or severe. Migraine intensity is not recommended as the main outcome measure alone, but it is important to record the decrease in migraine intensity as an indicator of disability reduction. Depending on the design of the trial, subjects should be asked to record the intensity of each migraine. In addition, the 11 point visual rating scale (VAS) can be used instead or in combination with the 4-level classification rating scale. The use of VAS in clinical trials may increase the likelihood of showing differences in severity.The 11-point visual analogue scale (VAS) has 10 scales, with a "0" end and a "10" end at both ends, where 0 means no pain, and 10 means the most severe pain that is unbearable. Headache data were captured through an electronic diary.
The Change of Cumulative Hours of Moderate / Severe Headache
The change of cumulative hours of moderate / severe headache per 4 weeks during the 12-week treatment period compared with baseline. Headache data were captured through an electronic diary.
The Change of Days without Symptoms
The change of days without symptoms per 4 weeks during the 12-week treatment period compared with baseline. Days Without Symptoms are defined as the number of days without aura, prodromal symptoms, headaches, pain and subsequent symptoms. It needs to be determined by headache diary.
The Change of Headache-free Days
The change of headache-free Days per 4 weeks during the 12-week treatment period compared with baseline. Headache-free days are defined as days with no headache or associated symptoms (including disability and cognitive/emotional impairment) that are directly attributable to migraine.
The Change of Migraine Disability Assessment questionnaire (mMIDAS) Score
The change of mMIDAS score per 4 weeks during the 12-week treatment period compared with baseline. The mMIDAS has 5 self-assessment items that calculate the missed work days and the missed household work days in the previous month. The mMIDAS also conducts assessments of disability in family, social, and leisure activities. The mMIDAS score is the sum of the scores of the 5 items. The score is multiplied by 3 for grading and is divided into 4 severe levels: I = 0-5 (slight disability); II = 6-10 (mild disability). Disability); Grade III = Grade 11-20 (moderate disability); Grade IV = above Grade 21 (severe disability).
The Change of Headache Impact Test (HIT-6) Score
The change of HIT-6 score per 4 weeks during the 12-week treatment period compared with baseline. The HIT-6 is a 6-question assessment used to measure the impact headaches have on a participant's ability to function on the job, at school, at home, and in social situations. It assesses the effect that headaches have on normal daily life and the participant's ability to function. Responses are based on frequency using a 5-point scale ranging from "never" to "always." The HIT-6 total score, which ranges from 36 to 78, is the sum of the responses - each of which is assigned a score ranging from 6 points (never) to 13 points (always).
The Change of Migraine Specific Quality of Life questionnaire(MSQ v2.1) Score
The change of MSQ v2.1 score per 4 weeks during the 12-week treatment period compared with baseline. The MSQ v2.1 is a 14-item questionnaire designed to measure health-related quality-of-life impairments attributed to migraine in the past 4 weeks. It is divided into 3 domains: Role Function Restrictive assesses how migraines limit one's daily social and work-related activities; Role Function Preventive assesses how migraines prevent these activities; and the Emotional Function domain assesses the emotions associated with migraines. Participants respond to items using a 6-point scale ranging from "none of the time" to "all of the time." Raw dimension scores are computed as a sum of item responses and rescaled to a 0 to 100 scale, where higher scores indicate better quality of life.
The Change of The Patient Global Impression of Change (PGIC) Score
The change of PGIC score per 4 weeks during the 12-week treatment period compared with baseline. The PGIC is a single item questionnaire used to measure the participant's impression of overall change in migraine since the first dose of study medication. The measure uses a 7-point rating scale with responses ranging from "very much better" to "very much worse."
The Change of Patient Health Questionnaire-9(PHQ-9) Score
The change of PHQ-9 score per 4 weeks during the 12-week treatment period compared with baseline. PHQ-9 consists of 9 diagnostic criteria in The Diagnostic and Statistical Manual of Mental Disorders(DSM)-IV involving depression within the last 2 weeks. Subjects were asked to indicate the frequency of 9 depressive symptoms in the last 2 weeks on a 4-point scale: 0 (none at all), 1 (a few days), 2 (more than half), and 3 (almost every day).The total score of PHQ-9 is between 0 and 27(from the best to the worst). 10-14 points may indicate moderate depression, and 15-19 points may indicate moderately severe depression; 20 to 27 points may have severe depression.
The Change of Generalized Anxiety Disorder (GAD-7) Score
The change of GAD-7 score per 4 weeks during the 12-week treatment period compared with baseline. GAD-7 is a proven, self-administered and concise tool for screening and diagnosing mental health disorders, which has been tested in the field in office practice. The screening scale is easy to use and can be completed in a short time, which improves the recognition rate of anxiety disorders and facilitates diagnosis and treatment. The main statistical index of this scale is the total score, that is, the sum of item scores. The total score range of GAD-7 is 0: 21 and that of GAD-2 is 0: 6. The score of GAD-7 can be used to evaluate the severity of anxiety symptoms: 0: 4: no clinical significance: anxiety: 5: 9: mild; 10: 14: moderate; > 15: severe. When used as an assistant diagnosis of anxiety symptoms, the cut-off value of GAD-7 is greater than or equal to 10.
The Change of Functional Impairment Scale (FIS) Score
The change of FIS score per 4 weeks during the 12-week treatment period compared with baseline. FIS is a four-point scale that assesses functional status and the intensity of impairment during daily activities. It can be used in conjunction with the four-point pain intensity scale and is usually completed daily and summarized over4-week intervals.
The Change of EuroQol-5 Dimension questionnaire (EQ-5D) Score
The change of EQ-5D score per 4 weeks during the 12-week treatment period compared with baseline. The EQ-5D is a self-administered standardized measure of health status. It consists of 2 components - the EQ-5D descriptive system and the EQ VAS. The descriptive system comprises of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). The EQ VAS records the respondent's self-rated health on a vertical, VAS where the endpoints are labelled "Best imaginable health state" and "Worst imaginable health state." The scoring range of the EQ VAS is from 0 (worst imaginable health) to 100 (best imaginable health).
The Change of Columbia-Suicide Severity Rating Scale (C-SSRS) Score
The change of C-SSRS score during the 12-week treatment period compared with screening period. The C-SSRS was designed to distinguish the domains of suicidal ideation and suicidal behavior,and the higher scores mean a worse outcome. Four constructs are measured:the severity of ideation(rated on a 5-point ordinal scale,and the higher scores mean more planned suicidal intent),the intensity of ideation subscale(comprises 5 items, each rated on a 5-point ordinal scale), the behavior subscale(rated on a nominal scale), the lethality subscale(assesses actual attempts; actual lethality is rated on a 6-point ordinal scale, and if actual lethality is zero, potential lethality of attempts is rated on a 3-point ordinal scale). Reports of suicidal ideation with intent to act and reports of actual, aborted, or interrupted suicide attempts or a behavior preparatory for making an attempt indicate subjects at high risk for suicide.

Brief Summary
In this study,288 adult migraine patients aged 18-65 years (diagnosed with migraine without aura and/or migraine with aura, with at least a 1-year history)will be collected to evaluate the efficacy, safety and tolerability of Anisodine Hydrobromide in preventing migraine attacks in episodic migraine in adults.
Detailed Description
Research contents: In this study,288 adult migraine patients aged 18-65 years (diagnosed with migraine without aura and/or migraine with aura, with at least a 1-year history)will be collected to evaluate the efficacy, safety and tolerability of Anisodine Hydrobromide in preventing migraine attacks in episodic migraine in adults. Research target: To evaluate the efficacy, safety and tolerability of oral Anisodine Hydrobromide in preventing migraine attacks in episodic migraine in adults, we used the change from baseline in migraine days per 4 weeks during the 12-week treatment period as the primary endpoint. Research design: This study uses a multicenter, randomized, double-blind, placebo-controlled, parallel design and plans to enroll 288 adult patients with episodic migraine. A total of 288 patients were planned to be enrolled, and all subjects were randomly assigned to group A (Anisodine Hydrobromide 1 mg bid) and group B (placebo 1 mg bid) according to a 1:1 ratio, with 144 subjects in each group.Both anisodine hydrobromide and placebo were produced and supplied by Chengdu First Pharmaceutical Limited Company. The enrolled subjects were orally administered Anisodine Hydrobromide 1 mg bid or placebo 1 mg bid for 12 consecutive weeks of treatment, and followed up for 4 weeks. That means doing face-to-face visits at the 4th, 8th, 12th and 16th weeks after dosing ,while affected by the epidemic or other special circumstances, video or telephone follow-up can be used. This study is divided into 3 phases: screening/baseline period (4 weeks, D-28~D-1), double-blind treatment period (12 weeks, D1~D84), follow-up period (4 weeks, D85-D112), a total of About 20 weeks. In order to ensure the quality of the trial, the sponsor and the researcher shall discuss and formulate the clinical research plan before the trial officially begins. Good Clinical Practice(GCP) training was given to the relevant researchers who participated in the experiment. The research center must manage experimental drugs in accordance with (SOP), including receipt, storage, distribution and recycling. In accordance with the GCP guidelines, necessary steps should be taken during the design and implementation phase of the study to ensure that the data collected are accurate, consistent, complete and credible. All observed results and abnormal findings in clinical trials should be verified and recorded in time to ensure the reliability of the data. The instruments, equipment, reagents and standards used in various examination items in clinical trials should have strict quality standards and ensure that they work under normal conditions. The researcher inputs the information required by the program into the eCRF, and the inspector verifies whether the filling is complete and accurate, and instructs the staff of the research center to make necessary corrections and supplements. The drug regulatory department, the institutional review committee (IRB)/ independent ethics committee (IEC), sponsor inspectors and / or inspectors may conduct systematic inspections of clinical trial-related activities and documents to evaluate whether trials are conducted in accordance with the requirements of the study program, SOP and relevant regulations (e.g. GCP, GMP), and whether trial data are recorded in a timely, true, accurate and complete manner. The inspection should be carried out by personnel who are not directly involved in the clinical trial. Statistical analysis plan: Efficacy evaluation: The primary endpoint was analyzed by Mixed Model for Repeated Measures(MMRM).And the primary endpoint analysis was based on the analysis results of Full Analysis Set(FAS) and Per Protocol Set(PPS).
