What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of patients with ACR20 (American College of Rheumatology 20 criteria) response
Time Frame: at 24 week of treatment.

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:

  1. Health Assessment Questionnaire-Disability Index (HAQ-DI),
  2. C-reactive Protein (CRP),
  3. Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),
  4. Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),
  5. Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)
at 24 week of treatment.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of patients with ACR50 (American College of Rheumatology 50 criteria) response
Time Frame: at 4, 8 and 12 weeks of treatment

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:

  1. Health Assessment Questionnaire-Disability Index (HAQ-DI),
  2. C-reactive Protein (CRP),
  3. Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),
  4. Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),
  5. Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)
at 4, 8 and 12 weeks of treatment
Number of patients with ACR70 (American College of Rheumatology 70 criteria)
Time Frame: at 4, 8 and 12 weeks of treatment

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:

  1. Health Assessment Questionnaire-Disability Index (HAQ-DI),
  2. C-reactive Protein (CRP),
  3. Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS),
  4. Patient's Global Assessment of Disease Activity-Visual Analog Scale (PtGADA-VAS),
  5. Physician's Global Assessment of Disease Activity-Visual Analog Scale (PhGA-VAS)
at 4, 8 and 12 weeks of treatment
Number of patients who achieved remission (DAS28(Disease Activity Score 28)<2.6) and low disease activity (DAS28≤3.2)
Time Frame: at 12 and 24 weeks of treatment

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
Changes in activity index DAS28
Time Frame: at 4, 8, 12 and 24 weeks of treatment

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 = 0.56√NPJ + 0.28√NSJ + 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
Changes in functional state of patients according to questionnaire HAQ -(Health Assessment Questionnaire- data)
Time Frame: at 4, 8, 12 and 24 weeks of treatment compared to baseline.
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. НАQ < 0.22 points - no effect; 0.22 ≤ ∆ НАQ ≤ 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.
