Efficacy and Safety of Shenqi Sherong Pill in Participants With Cervical Spondylotic Myelopathy

• Trial Design： This is a multi-center, randomized, double-blind, placebo-controlled phase III study，which plans to enroll 428 participants who will be randomized to Shenqi Sherong pill group or placebo control group. The Modified Japanese Orthopaedic Association (mJOA) Score combined with the changes of clinical symptoms and syndrome score are used as the validity index. The laboratory examination and incidence of adverse events are used as the safety index.
• Therapeutic schedule： Participants will be provided with neck braces and recommended to wear them daily or outdoors along with health education. Participants will be treated with the investigational drug (Shenqi Sherong Pill or placebo ) by taking two bags each time, three times a day at half an hour after breakfast, lunch and dinner for 6 weeks, with a 2-week follow-up after withdrawal.

Inclusion criteria

Participants can only be selected if they meet all the inclusion criteria

• Age 18-75 years old (including 18 and 75 years old), gender unlimited;
• Accord with Western medicine diagnosis standards of Cervical Spondylotic Myelopathy;
• Accord with Chinese medicine diagnosis standards of qi deficiency, blood stasis and kidney deficiency type;
• The disease classification was mild or moderate (13 ≤mJOA score ≤15);
• X-ray examination of six cervical vertebrae (frontal, lateral, hyperextension and flexion lateral and double oblique) indicates cervical degenerative changes, while MRI examination indicates spinal cord compression;
• The first diagnosis of Cervical Spondylotic Myelopathy within 3 months; for those diagnosed for more than 3 months, the investigator needs to determine that the condition is basically stable;
• Participants voluntarily participate in this experiment and sign an informed consent.

Note: 1) CT examination is determined by the investigator according to the specific conditions of participants. 2) Imaging materials of MRI, X-ray(frontal, lateral, hyperextension and flexion and double oblique), CT examination within 3 months from the 3A Grade hospital can be accepted ; 3) If the laboratory tests and 12-lead electrocardiogram are completed in the research center on the same day before the participant signing an informed consent, the examination can not be repeated after the investigator judging.

Exclusion criteria

Participants should be excluded if they meet any one exclusion criteria :

• The use of long-acting hormone drugs within 1 week before screening, or the last drug use is less than 7 half-lives, or Traditional Chinese Medicine, drugs with no marked half-life, physical therapy, etc. is less than 3 days before screening for the treatment of this disease;
• Participants with obvious concurrent syndrome or complication (such as Hypertension after taking antihypertensive drugs who systolic pressure ≥160mmHg, or diastolic pressure ≥100mmHg , or Diabetes after taking antidiabetic drugs who fasting blood glucose ≥10.0mmol/L and so on);
• MRI examination shows the degree of spinal stenosis is 1/2 or more, or the spinal cord compression caused by cervical spondylosis is three or more segments;
• Participants with severe hand muscle atrophy, or spasms, or is difficult to walk independently, or urinary dysfunction;
• Participants with cervical spine fracture, or congenital deformity of cervical spine, or ossification of ligamentum flavum, or ossification of posterior longitudinal ligament, or with neurological diseases such as lateral sclerosis and multiple sclerosis;
• Participants with visual analogue scale(VAS) score >7 points (7 points is defined as the distance between the left end and the mark location equal to 7.0cm);
• Participants with severe heart disease, such as myocardial infarction, unstable angina pectoris, Ⅲ to Ⅳ congestive heart failure and severe arrhythmia according to New York Heart Association (NYHA),or with severe liver and kidney diseases, or with abnormal liver and kidney function tests (Alanine aminotransferase or Aspartate aminotransferase ≥ 1.5 times the upper limit of normal, or creatinine clearance> the upper limit of normal); or with severe lung disease such as chronic bronchitis, asthma, chronic obstructive pulmonary disease(COPD) and other acute episodes;
• Participants with cerebral infarction and serious mental disorders;
• Woman in lactation, pregnancy, or planned pregnancy;
• Participant is allergic constitution or known to be allergic to the components of the investigational drug;
• Participants have participated or are participating in other clinical trials within 3 months;
• Participants are judged unsuitable for participation by the investigators in the study.

Note: 1) If examination or efficacy index score of visit 1 and visit 2 is overlapping item, the baseline standard is based on visit 2; 2) Participant who has the abnormal laboratory examination items during screening can be arranged for retest, whether to be enrolled or not will be comprehensively evaluated by the investigators.
