Overview

Brief Summary

This is a multicenter, randomized, double-blind phase2 study to evaluate the safety and investigate the efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of Hemay007 in Patients with moderate to severe Rheumatoid Arthritis who are on a stable dose of DMARDs.

Detailed Description

This study adopts a multi-center, randomized, double-blind clinical study design. Patients with moderate to severe active rheumatoid arthritis who meet the inclusion criteria but do not meet the exclusion criteria will be randomly assigned into the 600 mg QD group, 800 mg QD group, 1200 mg QD group and placebo group at a ratio of 1:1:1:1, with about 35 subjects in each group. Patients in all the groups will be treated with Hemay007 or placebo for 12 weeks, and observed for 4 weeks after the treatment. This study is to evaluate the safety and investigate the efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of Hemay007 in Patients with moderate to severe Rheumatoid Arthritis who are on a stable dose of DMARDs.

•If rheumatoid arthritis is moderately or severely active, the disease activity during the screening period and the baseline period must meet the following criteria:
•Swollen joints count (SJC) ≥ 6 (based on 66 joint count) and tender joints count (Tender joints count: TJC) ≥ 6 (based on 68 joint count) (if the same joint has both swelling and Tenderness, this joint is included in the counts of swollen joints and tender joints). Joints that have undergone major surgery and joints that have been intraarticularly injected with corticosteroids or hyaluronic acid within 2 weeks before screening or 6 weeks before randomization are not counted in TJC (tender joint count) and SJC (swollen joint count) count.
•Erythrocyte sedimentation rate (ESR)\>28mm/h or C-reactive protein (CRP) (or hypersensitive CRP (hsCRP))\>1.5 times the upper limit of the normal range (ULN).
•Subjects who have used at least one rheumatism-improving drug (DMARDs) treatment, but have poor efficacy (drug time ≥12 weeks, DAS28\>3.2) or intolerance (drug use interrupted due to adverse reactions) By.
•Methotrexate (MTX, 7.5-25 mg/week) has been used continuously for at least 12 weeks, and the dose has been stabilized for at least 4 weeks before the first administration, and a stable medication regimen shall be maintained during the trial period.
•If the subject is taking non-steroidal anti-inflammatory drugs (NSAIDS≤1), the dose must be stabilized for at least 2 weeks before the first administration. And/or oral corticosteroids (prednisone ≤10mg/day or equivalent dose), the dose must have been stabilized for at least 4 weeks before the first dose, and a stable medication regimen should be maintained during the trial period.
•The time to stop medication before the first dose meets the following criteria:
•For traditional medicines for improving rheumatism, such as:Sulfasalazine, hydroxychloroquine, cyclosporine, azathioprine drugs: stop the drug for 4 weeks before the first administration;

Exclusion Criteria

•Those who are known to be allergic to any component of hemay007 tablets.
•Those who have received any medical supportive treatments (such as whitening drugs, drugs for anemia (except folic acid), liver-protecting and enzyme-lowering drugs, blood transfusions, etc.) within 2 weeks before screening.
•The joint function classification of rheumatoid arthritis is Grade IV or those who need to stay in bed/sedentary wheelchair for a long time due to limited joint function activities.
•Those who have taken gold preparations or penicillamine in the past or during screening.
•In the past or at the time of screening, there were other inflammatory joint diseases other than RA (such as: gout, reactive arthritis, psoriatic arthritis, spondyloarthropathy, etc.). Or other joint diseases that may affect the evaluation of curative effect (such as: osteoarthritis with obvious joint pain), the investigator judged that it is not suitable to join the trial.
•Past or at the screening systemic autoimmune diseases (such as systemic lupus erythematosus, Felty syndrome, scleroderma, primary Sjogren's syndrome, etc., except for secondary Sjogren's syndrome), or organ-specific For autoimmune diseases (such as hyperthyroidism, Hashimoto's thyroiditis, etc.), the investigator has judged that it is not suitable to join this trial.
•Patients with acute myocardial infarction, unstable angina pectoris, stroke, and cardiac insufficiency (New York Heart Association (NYHA) cardiac function classification III/IV) within 6 months before screening.
•The cardiovascular, liver, kidney, lung, digestive tract, nervous system and other serious diseases (such as: poorly controlled severe diabetes, hypertension, interstitial pneumonia, obstructive Lung disease, bronchospasm, etc.), the investigator judged that it is not suitable to join the research.
•At the time of screening, the laboratory test (γ-interferon release test) was positive and met any of the following conditions. The investigator judged that the tuberculosis infection or suspected infection was.
•Chest imaging examination showed suspected tuberculosis infection; Active pulmonary tuberculosis; Those who have had active Mycobacterium tuberculosis infection within 3 years before screening; People who have been in contact with or have active tuberculosis in the home environment.
