About
BCD-089 is the original therapeutic monoclonal antibody binding the alpha subunit of the IL-6 receptor.
The aim of the study is to demonstrate the efficacy and safety of BCD-089 in combination with methotrexate in patients with active rheumatoid arthritis resistant to monotherapy with methotrexate.
Full description
BCD-089-3/SOLAR is the international, multicenter, double blind, placebo-controlled phase III clinical study.
The main period of the study (Weeks 0-24) is blinded; study subjects will receive BCD-089/placebo.
At Week 24 the study will become open-label and all patients will receive BCD-089 once a week for 4 weeks. At week 28 patients who achieved the RA remission at week 24 will be switched to BCD-089 Q2W dosing regimen and will receive it through Week 51. Patients who failed to achieve remission at week 24 will receive BCD-089 once a week through Week 51.

- Men and women aged 18 years or older on the day of signing the ICF.
- Verified rheumatoid arthritis according to the ACR 2010 criteria diagnosed at least 24 weeks before signing the ICF .
- Use of methotrexate for the last 12 weeks before signing the ICF.
- Use of a stable dose of methotrexate for the last 4 weeks before signing the ICF (the dose of methotrexate should be 15 to 25 mg per week). Methotrexate can be used at a dose of 10 mg in the case of intolerability/toxicity of higher doses.
- Inefficacy of methotrexate used for the last 12 weeks before signing the ICF (in the opinion of the Investigator).
- Active rheumatoid arthritis at randomization in the study.
- The ability of the patient (in the Investigator's opinion) to follow the Protocol procedures.
- Patients and their sexual partners of childbearing potential agree to use reliable contraceptive methods starting from signing the ICF, during the study and for 8 weeks from the last injection of the investigational product. This requirement does not apply to patients and their partners who underwent surgical sterilization and to women who are post-menopausal for at least 2 years. Reliable contraceptive methods include one barrier method in combination with one of the following: spermicides, intrauterine device/oral contraceptives.
Exclusion criteria

-
Patient's functional status: class IV according to the ACR 1991 classification.

-
Use of any of the following concomitant therapies:
- Oral prednisolone or its equivalent in a dose more than 10 mg/day;
- Need in oral prednisolone (or its equivalent) ≤ 10 mg if its dose was not stable during the last 4 weeks before signing the ICF (patients who used topical glucocorticoids are allowed to participate in the study);
- Need in NSAIDs if the dose was not stable during the last 4 weeks before signing the ICF (patients who have occasionally used NSAIDs for fever or allergy syndrome associated with an intercurrent disease can be included in the study);
