2. To prove the therapeutic equivalence of Etanercept, lyophilisate for solution for injection and Enbrel, lyophilisate for solution for subcutaneous injection in patients with rheumatoid arthritis.

3. To evaluate the immunogenicity of Etanercept, lyophilisate for solution for injection.

Description:

This is an open-label, randomized, comparative, multicentre study in parallel groups of the efficacy, safety and immunogenicity of Etanercept, lyophilisate for solution for injection and Enbrel, lyophilisate for solution for subcutaneous injection, in patients with rheumatoid arthritis.

Total duration of patient participation in the study will be 49-52 weeks. Of these: screening

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of patients with ACR20 (American College of Rheumatology 20 criteria) response	ACR20 responders are subjects with at least 20% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: Health Assessment Questionnaire-Disability Index (HAQ-DI),; C-reactive Protein (CRP),; Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),; Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),; Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)	at 24 week of treatment.
Secondary	Number of patients with ACR50 (American College of Rheumatology 50 criteria) response	ACR50 responders are subjects with at least 50% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: Health Assessment Questionnaire-Disability Index (HAQ-DI),; C-reactive Protein (CRP),; Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),; Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),; Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)	at 4, 8 and 12 weeks of treatment
Secondary	Number of patients with ACR70 (American College of Rheumatology 70 criteria)	ACR70 responders are subjects with at least 70% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: Health Assessment Questionnaire-Disability Index (HAQ-DI),; C-reactive Protein (CRP),; Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),; Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),; Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)	at 4, 8 and 12 weeks of treatment
Secondary	Number of patients who achieved remission (DAS28(Disease Activity Score 28)<2.6) and low disease activity (DAS28=3.2)	The DAS28 is a combined index for measuring disease activity in RA. The index includes swollen (range 0-28) and tender (range 0-28) joint counts, acute phase response (ESR in mm/hr), and general health status (participant global assessment of disease activity using VAS, range 1-100 mm).; DAS28, which uses a 28-joint count, is derived from the original DAS, which includes a 44-swollen joint count.; The DAS28 scale ranges from 0 to 10, where higher scores indicate worsening. DAS28 <2.6 equals (=) remission	at 12 and 24 weeks of treatment
Secondary	Changes in activity index DAS28	Changes in activity index compared to baseline. The DAS28 index takes into account information on safety and swelling of 28 joints, ESR and patients' global health assessment according to VAS.; Calculate DAS28 from the expression: DAS28 = 0.56vNPJ + 0.28vNSJ + 70lnESR + 0.014PGAH, where NPJ - number of painful joints at palpation (28 examined), NSJ - number of swollen joints (28 examined), PGAH - patient's global assessment of health in millimetres in 100 mm Visual Analog Scale (VAS), ESR - rate of erythrocyte sedimentation in mm/h, ln - natural logarithm.; According to the ACR criteria, the levels of the disease activity depending on the values of DAS28, are ranked as: remission - DAS28 <2.6; low - DAS28 =3.2; moderate - DAS28 3.3-5.1; high - DAS28 >5.1.; To calculate DAS28, use the official online calculator: http://www.das-score.nl/das28/DAScalculators/dasculators.html and https://www.das-score.nl/das28/DAScalculators/dasculators.html	at 4, 8, 12 and 24 weeks of treatment
Secondary	Changes in functional state of patients according to questionnaire HAQ -(Health Assessment Questionnaire- data)	Changes in functional state of patients according to questionnaire HAQ DI -(Health Assessment Questionnaire Disability Index) compared to baseline. It includes the categories of dressing and grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. It asks patients about the amount of difficulty they experience in these activities as well as the use of aids and/or devices. The HAQ has a numeric rating scale (NRS) (13) to assess pain on a scale from 0 to 10.Grades to evaluate the treatment efficacy using the HAQ DI. The minimal clinically significant change in the HAQ DI, which corresponds to the difference in parameters before and after treatment, is equal to 0.22. ??Q < 0.22 points - no effect; 0.22 = ? ??Q = 0.36 - lowest effect (20% improvement according to ACR criterion); 0.36 = ? HAQ < 0.80 - satisfactory effect (50% improvement according to ACR criterion); HAQ = 0.80 points - highest effect (70% improvement according to ACR criterion).	at 4, 8, 12 and 24 weeks of treatment compared to baseline.
