1. Voluntarily sign the informed consent form;
2. Age between 18 and 75 years inclusive;
3. Diagnosed with RA according to the 1987 American College of Rheumatology (ACR) criteria or the 2010 ACR and European League Against Rheumatism (EULAR) classification criteria;
4. At the time of screening, judged to have moderate to severe active RA based on the following criteria: joint swelling count ≥6 (out of 66 joints) and joint tenderness count ≥6 (out of 68 joints), and must also meet C-reactive protein (CRP)/High-sensitivity C-reactive protein (hsCRP) ≥ upper limit of normal (ULN) or erythrocyte sedimentation rate (ESR) ≥28 mm/h;
5. Have been receiving oral methotrexate (MTX) treatment for at least 12 weeks and at a stable dose (MTX dose of 7.5\~25 mg/week) for at least 4 weeks prior to randomization; subjects with a history of parenteral MTX (subcutaneous, intramuscular, or intravenous injection) are eligible for the study, but these subjects must have been receiving a stable dose of MTX 7.5\~25 mg/week oral treatment for ≥4 weeks prior to randomization;
6. At the time of screening, if the subject is taking prednisone or an equivalent dose of corticosteroids, they must have been on a stable dose (prednisone dose ≤10mg/day) for at least 4 weeks prior to randomization.
You may not be if
1. Body weight \>100 kg or \<40 kg;
2. ACR functional class IV or long-term bedridden/wheelchair-bound individuals;
3. Individuals with an allergic constitution or known allergies to any components of the study treatment or other similar products;
4. Investigators determine that surgeries previously received by the subject or planned surgeries may affect the assessment of joint study evaluations;
5. Patients with rheumatic immune diseases other than rheumatoid arthritis, uncontrolled immune system diseases requiring oral corticosteroid treatment, which the investigator deems may affect trial evaluation;
6. Primary or secondary immunodeficiency diseases (past or currently active);
7. History of or current tumors (except for cured and non-recurrence for at least 5 years of skin basal cell carcinoma, squamous cell carcinoma, cervical carcinoma in situ, breast ductal carcinoma in situ, and papillary thyroid carcinoma);
8. History of any lymphoproliferative diseases, such as EBV-related lymphoproliferative diseases, lymphoma, leukemia, myeloproliferative diseases, multiple myeloma, or signs and symptoms suggesting current lymphatic diseases;
9. Presence of severe, poorly controlled comorbidities, such as (but not limited to) neurological, cardiovascular, liver, kidney, gastrointestinal, endocrine diseases, which the investigator judges may hinder the subject's participation in this study;
10. Known to have the following infections: recurrent active bacterial, viral, fungal, mycobacterial, or other infections \[including but not limited to tuberculosis and atypical mycobacterial disease, granulomatous disease found on chest X-ray, hepatitis C virus infection, human immunodeficiency virus (HIV) infection, and herpes zoster, but excluding nail bed fungal infections\], or a history of chronic infections within the last 6 months, or any major infection requiring hospitalization for treatment or intravenous antibiotic treatment within 4 weeks before screening or oral antibiotic treatment within 2 weeks before screening;
11. Subjects who have received live vaccines/attenuated vaccines within 4 weeks before the screening visit or are known to receive live vaccines/attenuated vaccines during the 12-week treatment observation period;
12. Subjects who have used or plan to use lymphocyte-depleting agents/therapies, alkylating agents, total lymphoid irradiation, or other treatment methods during the study period;
13. Individuals who have previously received IL-6 and IL-6R inhibitor treatment;
14. Use of biological disease-modifying anti-rheumatic drugs (bDMARDs) within 4 weeks or 5 half-lives (whichever is longer) before randomization: such as TNF-α inhibitors, biosimilars, and RA drugs used in clinical trials;
16. Receipt of intra-articular or extra-articular (intramuscular, intravenous) corticosteroid treatment within 28 days before dosing;
17. Participation in other drug clinical studies within 1 month or 5 half-lives (whichever is longer) of other trial drugs before screening;
18. Hepatitis B surface antigen (HBsAg) positive, or if hepatitis B core antibody (HBcAb) is positive, then HBV DNA is additionally checked and HBV DNA \> lower limit of detection;
19. Screening period laboratory test values (only one retest is allowed) meet any of the following conditions:
* Serum creatinine: Female subjects with serum creatinine \> 1.4 mg/dL (124 μmol/L); male subjects with serum creatinine \> 1.6 mg/dL (141 μmol/L);
* ALT or AST \> 1.5 times the upper limit of normal (ULN);
* Platelet count \< 80×10\^9/L;
* WBC \< 3.0×10\^9/L;
* Total bilirubin \> 1.5 times ULN;
* Neutrophil count \< 1.5×10\^9/L;
* Lymphocyte count \< 0.5×10\^9/L.
20. Pregnant or breastfeeding women, or female subjects with positive pregnancy tests during the screening period/baseline period, or subjects (including male subjects and their female spouses) who cannot take effective contraceptive measures from the screening period to 6 months after completion or termination of the trial;
