简要总结
To evaluate the efficacy of different dosing regimens of Botulinum Toxin Type A for Injection (HengLi®) in the treatment of trigeminal neuralgia (TN), so as to determine the optimal dosing regimen of the best administration scheme of Botulinum Toxin Type A for Injection (HengLi®) in the treatment of TN.
详细描述
This study plans to enroll 240 subjects, and the efficacy measures [VAS score, DSIS score, daily pain duration (if applicable), and number of daily pain episodes] will be collected from subjects using the electronic Patient-Reported Outcomes (ePRO) throughout the study. The study period mainly consists of a screening period (14 days before the first dose), a double-blind treatment period (from the first dose to Week 12), and an extension period (from Week 13 to Week 52), including a maximum of 4 treatment cycles (each cycle lasts 12 week)

入选标准
- •Understand and voluntarily sign the written ICF;
- •Male or female 18 to 75 years of age (inclusive), able to provide legal identification;
- •Subjects clinically diagnosed as classical or idiopathic TN, with pain in one or two divisions (diagnostic criteria in the International Classification of Headache Disorders, 3rd Edition [ICHD-3], see Appendix 6);
- •Have a mean daily VAS score of ≥ 40 mm for 7 consecutive days during the screening period, with mean number of daily episodes ≥ 2, and duration of pain ≥ 3 months at screening;
- •Have a clear consciousness, the ability to perceive and resolve pain, the ability to understand and cooperate with the clinical study process, and the ability to comply with the requirements of the study protocol until completion of the study;
- •Prior first-line drug therapy (carbamazepine, oxcarbazepine) for TN;
- •Women of childbearing potential (WOCBP) should have a negative pregnancy test within 7 days prior to the first dose, and subjects and their partners should have no pregnancy plan and promise to use a medically acceptable contraceptive measure (e.g., intrauterine device [IUD], contraceptive pill or condom) during the study drug treatment period and within 3 months after the last dose of study drug; Note: WOCBP is defined as non-postmenopausal women who have experienced menarche and have not undergone sterilization (hysterectomy or bilateral adnexectomy) or other causes of permanent infertility (e.g., mullerian agenesis) identified by investigator. Postmenopause is defined as amenorrhea for ≥12 months without other biological or physiological causes.
排除标准

- •Change in the dose and type of drugs for treatment of TN changed within 4 weeks prior to the first dose (including carbamazepine, oxcarbazepine, gabapentin, lamotrigine, etc.);
- •Subjects who have received injection therapy (magnesium sulfate injection), physical therapy, or traditional Chinese medicine treatment of TN within 4 weeks prior to the first dose, such as ultrashort wave, magnetic therapy, acupuncture, traditional Chinese medicines, etc.;
- •Patients who have received any botulinum agent within 6 months prior to the first dose;
- •Patients with secondary TN confirmed by magnetic resonance imaging (MRI);
- •Patients with systemic neuromuscular junction disorders, such as myasthenia, Eaton Lambert syndrome, amyotrophic (spinal cord) lateral sclerosis, multiple sclerosis, etc.;
- •Subjects who have used drugs affecting neuromuscular junction within 7 days prior to the first dose (for example, aminoglycoside antibiotics [e.g., gentamycin, etc.], quinine, and penicillamine) or need to use the above drugs, cholinesterase antagonists, succinylcholine, curare-like depolarizing antagonists, magnesium sulfate, quinidine, calcium channel blockers (excluding antihypertensive agents such as amlodipine besylate and nifedipine), lincomycin, polymyxin, etc. during the conduct of the clinical trial;
- •There are conditions that investigator believes may affect pain assessment, such as skin disorders in the affected skin areas and may affect sensation, or the recommended injection sites have localized infection or are locally accompanied by other skin disorders;
- •Concurrent or prior hemorrhagic conditions, or intake of anticoagulants [e.g. heparin, coumarins, non-vitamin K antagonists, oral anticoagulants (e.g., apixaban, dabigatran, edoxaban, rivaroxaban), but aspirin and other platelet aggregation inhibitors such as ticlopidine, clopidogrel, prasugrel, abciximab, eptifibatide, and tirofiban are allowed] within 10 days prior to injection;
- •Chronic systemic diseases, which may affect subject's participation in the study as assessed by investigator, including but not limited to:
- •1）、Severe cardiopulmonary diseases, such as unstable angina pectoris, myocardial infarction, and severe arrhythmia, World Health Organization (WHO) cardiac function classification of Class III to IV at screening, hypertension poorly controlled with active treatment, systolic blood pressure > 160 mmHg or diastolic blood pressure > 100 mmHg at the time of screening; recurrent asthmatic attacks, etc.; 2）、Cerebrovascular accident (e.g., cerebral infarction, transient ischemic attack, etc.) within 6 months prior to screening; 3）、History of malignant tumor (excluding cured skin basal cell carcinoma, carcinoma in situ, and papillary thyroid carcinoma) or history of anti-tumor treatment within 5 years prior to screening; 4）、Other severe or unstable medical conditions (such as systemic infection, lung diseases, liver, cardiovascular, kidney or gastrointestinal diseases, etc.) assessed by investigator; 11、Severe hematological, liver, and renal dysfunction, with any one of the following clinical laboratory test results:
- •、Hematology: neutrophil count (ANC) < 1.5 × 109/L, or platelet count < 90 × 109/L, or hemoglobin < 100 g/L;
- •、Hepatic function: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2.5 × upper limit of normal (ULN); or total bilirubin (TBIL)> 1.5 × ULN;
- •、Estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 (calculated according to the simplified MDRD formula); 12、Presence of nervous/mental system disorders, which, in the investigator's opinion, may affect the evaluation of TN or self-scoring, including psychiatric disorders such as epilepsy, recurrent dizziness, headache, memory and cognitive impairment, severe depression, and schizophrenia, or other nervous system disorders except TN, such as headache and migraine; 13、Pregnant women and subjects in pregnancy or lactation; 14、Patients with known hypersensitivity to botulinum toxin type A and any ingredient in the formulation (sucrose, dextran, and gelatin) or with an allergic constitution; 15、Use of prohibited medications (see Section 6.
- •prior to screening. If a subject has used any prohibited medication before screening, screening is not allowed unless medication have been discontinued for at least 5 half-lives (see the labeling for the specific half-life) before the signing of ICF, and the medication is prohibited throughout the study; 16、Known history of drug/alcohol abuse; 17、Hepatitis B virus deoxyribonucleic acid (HBV-DNA) higher than the upper limit of detection, hepatitis C virus antibody (HCV-Ab) and HCV ribonucleic acid (RNA) positive, human immunodeficiency virus antibody (HIV Ab) positive, and serum Treponema pallidum antibody (TPPA method) positive at screening, or any of them; 18、Corneal ulcer; 19、Other conditions that make use of botulinum therapy unsuitable or may damage the safety of subjects or may make it impossible to complete the study in compliance with the protocol, as assessed by investigator.
