Primary Outcome Measures:
  • Percentage of Participants Achieving Sustained Remission Rate At Week 104 [ Time Frame: Week 104 ] [ Designated as safety issue: No ]
    Sustained remission rate (SRR) is defined as Disease Activity Score 28 (DAS28) <2.6 during ≥ 23 weeks and no more than 4 swollen joints (28 joint count) due to RA at Week 24 of remission, with the exception of up to 2 in-between DAS28 values which could be between 2.6 and 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.

The DAS28 is a combined index for measuring disease activity in RA. The index includes swollen and tender joint counts (range 0-28), 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.

Each dimension is rated on a 3-point response scale as 1 = no problems, 2 = some/moderate problems, 3 = extreme problems. The responses to the five EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 to 1, where '1' indicating full health and '0' representing dead. The positive values indicate that during the study the health status improved. 2) EQ-VAS on a scale of 0 to 100, where 0 = worst possible health status and 100 = best possible health status."

  • Number of Participants With Any Adverse Events, Any Serious Adverse Events, and Adverse Events Leading to Discontinuation [ Time Frame: Up to Week 104 ] [ Designated as safety issue: No ]
    An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign , symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. A serious adverse event is defined as any event which was fatal (resulted in death), lifethreatening (with immediate risk of death), resulted in a new or prolongation of a current hospitalization, resulted in persistent or significant disability or incapacity, was a congenital anomaly or birth defect, considered medically significant by the investigator, required intervention to prevent one or more of the outcomes listed above.

  • Number of Participants With Clinically Significant Laboratory Values at Week 12 [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Laboratory parameters included hematology, chemistry and lipids. Any treatment-emergent abnormal laboratory result accompanied by clinical symptoms or leading to a change in study medication or requiring a change in concomitant therapy was considered clinically significant. Participants with clinically significant laboratory values are reported in the below table.

  • Number of Participants With Clinically Significant Laboratory Values at Week 24 [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
    Laboratory parameters included hematology, chemistry and lipids. Any treatment-emergent abnormal laboratory result accompanied by clinical symptoms or leading to a change in study medication or requiring a change in concomitant therapy was considered clinically significant. Participants with clinically significant laboratory values are reported in the below table.

  • Number of Participants With Clinically Significant Laboratory Values at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
    Laboratory parameters included hematology, chemistry and lipids.

Detailed Description:

Multi-center, randomized, double-blind, placebo-controlled (double placebo) three-arm parallel group, comparative study. Patients were randomized in a 1:1:1 ratio to one of the following treatments:

  • TCZ 8 milligram (mg)/kilogram (kg) + MTX (Group I: TCZ+MTX)
  • TCZ 8 mg/kg + placeboMTX (Group II: TCZ+placebo)
  • MTX + placeboTCZ (Group III: MTX+placebo)

Randomization was stratified by participating center and baseline Disease Activity Score, scoring 28 joints (DAS28) level (<5.1 vs. ≥5.1). Patients were evaluated every 4 weeks and at each visit a decision on dosage changes was made based on efficacy parameters (DAS28) and occurrence of adverse events (AEs). Patients received MTX/placeboMTX in climbing dosages. Hydroxychloroquine (HCQ) was added when remission was not reached with the maximum tolerable dosage (MTD) of MTX/placeboMTX. If after 12 additional weeks remission was not reached, HCQ was stopped and replaced by standard of care therapy (in Group I) or placebo therapy was replaced by the corresponding verum resulting in TCZ+MTX combination therapy (in Groups II and III). In case remission was reached, MTX/placeboMTX and TCZ/placeboTCZ had to be decreased. Patients were followed for a maximum of 24 months
