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.

Eligibility criteria: Inclusion Criteria:

* Aged between 18 and 75 years old (both ends included, subject to the date of signing the informed consent form), male or female.
* According to the 1987 American College of Rheumatology (ACR) or 2010 ACR/EULAR classification diagnostic criteria, the diagnosis was rheumatoid arthritis, and the course of disease was ≥12 weeks.
* 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.

* 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;

Leflunomide: The drug should be stopped for 12 weeks before the first dose, or cholestyramine should be eluted for 11 days, and the drug should be stopped for 7 days before the first dose.
