Detailed Description
- Research contents:
In this study,189 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 Tizanidine Hydrochloride in preventing migraine attacks in episodic migraine in adults.
- Research target:
To evaluate the efficacy, safety and tolerability of oral Tizanidine Hydrochloride 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 189 adult patients with episodic migraine.
- A total of 189 patients were planned to be enrolled, and all subjects were randomly assigned to group A (Tizanidine Hydrochloride 1 mg Tid) , group B (Tizanidine Hydrochloride 2 mg Tid) and group C (placebo 1 tablet Tid) according to a 1:1 :1ratio, with 63 subjects in each group. All Tizanidine Hydrochloride and placebo were produced and supplied by Sichuan Credit Pharmaceutical Co. Ltd.
The enrolled subjects were orally administered Tizanidine Hydrochlorid and placebo for 12 consecutive weeks of treatment, and followed up for 12 weeks. That means doing face-to-face visits at the 4th, 8th, 12th and 16th weeks after dosing .
This study is divided into 3 phases: screening/baseline period (4 weeks, D-28D-1), double-blind treatment period (12 weeks, D1D84), 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.

The change of migraine days per 4 weeks during the 12-week treatment period mpared 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 [12-week treatment period（Day 1-Day 84）]
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 [12-week treatment period（Day 1-Day 84）]
The change of days with moderate / severe headache per 4 weeks during the 12-week treatment period compared with baseline. Headache data were captured through an electronic diary.

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 Change of Frequency of Medications Use [12-week treatment period（Day 1-Day 84）]
The Change of Frequency of Medications Use [Time Frame: 12-week treatment period（Day 1-Day 84）] 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 [12-week treatment period（Day 1-Day 84）]
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 [12-week treatment period（Day 1-Day 84）]
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.

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 [12-week treatment period（Day 1-Day 84）]
The change of HIT-6 score per 4 weeks during the 12-week treatment period compared with baseline.

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 [12-week treatment period（Day 1-Day 84）]
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 [12-week treatment period（Day 1-Day 84）]
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 [12-week treatment period（Day 1-Day 84）]
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 [12-week treatment period（Day 1-Day 84）]
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.
