Trial Outcomes & Findings for An Observational Study of MabThera (Rituximab) in Patients With Rheumatoid Arthritis And Inadequate Response Or Intolerance to a First Anti-TNF Alpha Therapy (NCT NCT01592292)

NCT ID: NCT01592292

Last Updated: 2016-08-22

Results Overview

DAS28 is calculated from the number of swollen joints and tender joints using the 28-joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hr\]) and patient's global assessment of disease activity (participant-rated arthritis activity assessment) with transformed scores ranging 0 (minimum score) to 10 (maximum score); higher scores indicated greater affectation due to disease activity. A DAS28 score of less than or equal to (=\<) 3.2 = low disease activity, a DAS28 score of \>3.2 to 5.1 = moderate to high disease activity.

Participant Flow

The arm Other anti-TNF agent consisting of participants treated with adalimumab, etanercept and infliximab was divided into individual treatment groups only for the purpose of Participant flow reporting. All other analyses were performed in Rituximab versus Other anti-TNF agent.

PRIMARY outcome

Timeframe: Baseline and Month 6

Population: The ITT set included participants who offered end-point results among participants who received study drugs after enrollment and met all inclusion/exclusion criteria.

DAS28 is calculated from the number of swollen joints and tender joints using the 28-joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hr\]) and patient's global assessment of disease activity (participant-rated arthritis activity assessment) with transformed scores ranging 0 (minimum score) to 10 (maximum score); higher scores indicated greater affectation due to disease activity. A DAS28 score of less than or equal to (=\<) 3.2 = low disease activity, a DAS28 score of \>3.2 to 5.1 = moderate to high disease activity.

TJC is a clinical method to quantify abnormalities in participants with RA. It is associated with the level of pain. The number of tender joints were scored as tender=1 and not tender=0, and counted. A negative change from baseline represents an improvement (a reduction in the number of tender joints).

The HAQ-DI is a participant-completed questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. Each domain has at least two component questions. There are four possible responses for each component ranging from 0 (without any difficulty) to 3 (unable to do). The overall HAQ-DI score is the average of each of the 8 category scores and ranges from 0 to 3, where 0 represents no disability and 3 very severe, high-dependency disability.

An AE was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. ADRs were defined as any response to a drug which was noxious and unintended, and which occurred at dose normally used related to the pharmacological properties. A SAE was any experience that: resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was medically significant.
