Study to Examine Efficacy and Safety of Rituximab in Participants With Rheumatoid Arthritis (RITAM)

September 2, 2016 updated by: Hoffmann-La Roche

Post Marketing Non Interventional Clinical Research of Administration of Rituximab in Rheumatoid Arthritis

This Phase IV post-marketing, non-interventional, open label, non-comparative and prospective study will examine the efficacy and safety of rituximab in participants who had previously received rituximab in terms of everyday medical practice. Efficacy and safety of rituximab will be determined 24 weeks after receiving the first infusion, 24 weeks after the second infusion repeated courses of treatment (if the participants receive another course of rituximab) and 24 weeks after the third infusion repeated courses of treatment (if the participants receive third course of rituximab). Protocol does not specify the criteria for initiation of treatment with rituximab and procedure of the infusion of rituximab. Rituximab will be administered at the discretion of treating physician according to approved label.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Participants receiving rituximab no longer than 4 weeks for the treatment of rheumatoid arthritis before the start of study.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Rheumatoid arthritis participants
Participants who were on rituximab for rheumatoid arthritis and who will continue receiving rituximab treatment (at the discretion of treating physician) according to previous approved indication will be observed for a period of 72 weeks.
Drug: Rituximab
Rituximab will be administered at the discretion of treating physician according to approved label. Protocol does not specify/enforce the criteria for initiation of treatment with rituximab and procedure of the infusion of rituximab.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Reduction From Baseline in Disease Activity Score Based on 28 Joints Count (DAS28) of More Than 1.2 Units After 24 Weeks of First Rituximab Infusion
Time Frame: Baseline, 24 weeks after first rituximab infusion (Week 24)
DAS28 score is a measure of participant's disease activity calculated using tender joint count [28 joints] (TJC28), swollen joint count [28 joints] (SJC28), participant's global assessment of disease activity (PGH) [visual analog scale (VAS): 0=no disease activity to 100=maximum disease activity] and erythrocyte sedimentation rate (ESR). DAS28 was calculated according to following formula: [0.56 multiplied by (*) square root (√) of TJC] plus (+) [0.28*√SJC]+[0.70*the natural logarithm (ln) ESR]+[0.014*PGH]. Total possible score of 0 to approximately 10, where higher scores represented higher disease activity. Scores below 2.6 indicated clinical remission, score of less than or equals to (</=) 3.2 indicated low disease activity, score of greater than (>) 3.2 to </=5.1 indicated moderate disease activity, scores above 5.1 indicated high or severe disease.
Baseline, 24 weeks after first rituximab infusion (Week 24)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With European League Against Rheumatism (EULAR) Good Response
Time Frame: Baseline, Weeks 24, 48 and 72
Clinical response was assessed according to EULAR categorical DAS28 response criteria, which defined clinically meaningful improvement at Weeks 24, 48, and 72. EULAR response was based on change from baseline (CFB) in DAS28 score and on actual DAS28 score, at Weeks 24, 48, and 72. DAS28 score: participant's disease activity calculated using TJC28, SJC28, PGH [VAS: 0=no disease activity to 100=maximum disease activity] and ESR. DAS28 was calculated by following formula: (0.56*√TJC)+(0.28*√SJC)+(0.70*ln ESR)+(0.014*PGH). Total possible score = 0-10, higher scores represented higher disease activity. EULAR Good response: DAS28</=3.2; reduction of DAS28 >1.2.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
