Detailed Description
This is a non-inferiority trial. The primary outcome is the percentage of subjects achieving ACR20. According to the global instruction of Remicade, the effective rate of Remicade is 50%, and the placebo is 20%. Calculate the critical value δ=(50%-20%)×50%=15%, one-side α=0.025, β=0.20, experimental group : control group = 1:1, the results are: CMAB008 group 175 participants, control group 175 participants, 350 participants in total. Take 10% drop-out into consideration, the finial sample sizes are: CMAB008 group 196 participants, control group 196 participants, 392 participants in total.
During the entire duration of the study, all adverse events (AE) and all serious adverse events (SAEs) are collected, fully investigated and documented in source documents and case report forms (CRF). Study duration encompassed the time from when the participant sign the informed consent until the last protocol-specific procedure has been completed, including a safety follow up period.
This study will be conducted in compliance with the protocol, the current version of the Declaration of Helsinki, the guidelines of Good Clinical Practice (GCP) as well as all national legal and regulatory requirements.

- AIDS-infected patient or HIVpositive;
One of the following situations relating to tuberculosis:
- Concurrent or previous active tuberculosis. Chest X-ray examination (suggest chest anteroposterior and lateral position films) should be performed in the last 3 months before screening, to provide evidence for concurrent or previous tuberculosis;
- Intimate contact with active tuberculosis patient recently; or high-risk and/or immunocompromised group (e.g., long-term use of glucocorticoids, immunosuppressor), and with any signs of latent tuberculosis infection;
- PPD test (inject 5IU TB-PPD intradermally, measure the diameter of skin induration 72 hours later) performed in the last 3 weeks before screening: diameter of induration≤15mm, and with vesicle or necrosis; or diameter of induration>15mm;
- If cannot perform PPD test, perform T-SPOT test: T-SPOT test positive, chest file and clinical evidence indicate that the patient is unsuitable for participation;
- History of organ allograft operation (except for keratoplasty more than 3 months before the first use of investigational drug);
- Concurrent or previous malignant tumor (except for total excision and no recurrence of cutaneous squamous cell carcinoma, basal-cell carcinoma or carcinoma in situ of cervix) in the last 5 years before screening;
- History of lymphoid malignancies (lymphoma) or lymphoproliferative disease; or symptoms and signs indicate that may be lymphoproliferative disease (e.g., lymph node enlargement at neck, clavicle or axilla) during screening; or splenomegaly (≥subcostal 2cm);
- Concurrent or previous demyelinating diseases of the central nervous system (e.g., multiple sclerosis);
- Concurrent or previous congestive heart failure;
- Concurrent or previous other autoimmune disease, and may be expected to affect the assessment of investigational drug;
- Severe, progressive, uncontrolled cardiovascular, hepatic, renal, pulmonic, gastrointestinal, hematopoietic, endocrine, neural diseases, or other situations that the patient is considered as unsuitable for participation by investigator;
- History of severe drug or alcohol abuse with clinical symptoms; history of poor drug compliance; or other situations that may interfere protocol compliance (e.g., mental disease, frequent travel, lack of willingness);
- Laboratory tests results meet one of the following indexes: HGB<8.5g/dL, WBC<3.5*10^9/L, PLT<80*10^9/L, ALT/AST>2*upper limit of normal value, CREA>upper limit of normal value;

Improvement rate=(before the treatment - after the treatment)/before the treatment *100%. Visual Analogue Scale(VAS) is designed to present to the respondent a rating scale. Respondents mark the location on the 10-centimeter line corresponding to the amount of pain they experienced. VAS data of this type is recorded as the number of centimeters from the left of the line with the range 0-10. No pain <-- 10 cm. --> Pain as bad as possible |

|
Improvement rate=(before the treatment - after the treatment)/before the treatment *100%. The Health Assessment Questionnaire (HAQ) Disability Index assesses a patient's level of functional ability. There are 20 questions in eight categories of functioning which represent a comprehensive set of functional activities - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. The patient's responses are made on a scale from zero (no disability) to three (completely disabled). |
