Eligibility Criteria
You may qualify if:
- At the time of signing the informed consent form, the age of 18 ≤ 60, regardless of gender.
- kg/m2 ≤ body mass index (BMI) ≤ 35kg / m2, male weight ≥ 50kg, female weight ≥ 45kg.
- Women of childbearing age need to be able to ensure effective contraception (medically approved contraceptive measures, such as intrauterine device, contraceptive pill or condom) during the trial and within 3 months after the end of the trial.
- According to the diagnostic criteria of diagnostic and Statistical Manual of mental disorders (5th Edition) (dsm-5), it was diagnosed as severe depressive disorder, marked as moderate or severe, and without psychotic characteristics.
- The total score of Montgomery Asperger Depression Scale (MADRS) in screening period and baseline was ≥ 22, and the CGI-S score was ≥ 4.
- Compared with the screening period, the change in the total MADRS score at baseline did not exceed 25% of the screening period.
- The patients fully understand the purpose and requirements of the trial, voluntarily participate in the clinical trial and sign the written informed consent, and are willing to complete the whole trial process according to the trial requirements.
You may not qualify if:
- It meets dsm-5 diagnostic criteria for other mental disorders.
- A depressive episode secondary to physical or other mental illness.
- The researchers determined that there was a high risk of suicide: there were serious suicides and self injuries within 1 month before or during the screening; Or those who answered "yes" to item 5 of "suicidal ideation" in the screening Columbia suicide severity rating scale (c-ssrs).
- The depressive episode is ineffective after sufficient treatment with one or more antidepressants (at least 6 weeks according to the dosage in the manual).
- Those who had received electroconvulsive therapy (ECT) within 1 month before screening.
- Patients who have received other stem cell therapy.
- Have a history of infection within 1 month before screening and need hospitalization and / or antibiotic treatment; Or currently using systemic sex hormones (glucocorticoids), immunosuppressants or cytotoxic therapy.
- Screening the patients who had been diagnosed with hyperthyroidism or hypothyroidism within the previous year and are still taking drugs; Or have a history of thyroid disease and thyroid stimulating hormone (TSH) is higher than 1.2 times the upper limit of normal value or lower than 0.8 times the lower limit of normal value;
- Patients with a history of epilepsy (excluding children's history of fever and convulsion).
- Persons with severe alcohol or drug dependence within 1 year before screening (excluding caffeine or nicotine); Or daily alcohol intake of or above 5 units (1 units =360mL wine or 45mL Baijiu or 120mL wine).
- Accompanied by severe or unstable cardiovascular, respiratory, liver, kidney, blood, endocrine and central nervous system diseases.
- Laboratory examination was abnormal, and the researcher determined that it was of important clinical significance, such as: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) exceeded 2.5 times the upper limit of normal; Total bilirubin (TBIL) exceeds 1.5 times of the upper limit of normal value; Creatinine (CR) exceeded 1.2 times the upper limit of normal.
- QTc interval of ECG in screening stage \> 450 ms (male) or 470 MS (female); Or have a family history of long QT interval syndrome, or have cardiac insufficiency, severe arrhythmia or ischemic heart disease and need drug treatment, have congenital heart disease, severe organic heart disease or have a history of this disease.
- HIV antibody, HBsAg, HCV antibody or syphilis serological test results are positive.
- Participated in clinical trials of other drugs within 30 days before screening.
