Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Rituximab
Treatment: Drugs - Methotrexate
Treatment: Drugs - Methylprednisolone
Treatment: Drugs - Folic Acid

Experimental: Rituximab - Participants will receive rituximab 1 gram intravenously (IV) on Days 1 and 15 of each course of retreatment. In addition, participants will receive methotrexate 10-25 milligrams per week (mg/week) orally or parenterally, methylprednisolone 100 mg IV 30 minutes prior to both rituximab infusions, and a stable dose of folic acid greater than or equal to (\>=) 5 mg/week or equivalent. Participants will receive retreatment (next course of rituximab repeat treatment) within 2 weeks of meeting the retreatment criteria as defined in the protocol (minimum of 24 weeks after the first \[Day 1\] infusion of the last course of rituximab). Repeat treatment will be based on the investigator's decision of prior clinical response to rituximab, clinical need and evidence of active disease (Disease Activity Score in 28 joints \>=2.6). Retreatment with rituximab will be continued until withdrawal of consent or study treatment completion on 31 December 2011, whichever is sooner.


Treatment: Drugs: Rituximab
Participants will receive rituximab 1 gram IV on Days 1 and 15 of each course of retreatment.

Treatment: Drugs: Methotrexate
Participants will receive methotrexate 10-25 mg/week orally or parenterally.

Treatment: Drugs: Methylprednisolone
Participants will receive methylprednisolone 100 mg IV 30 minutes prior to each rituximab infusion.

Treatment: Drugs: Folic Acid
Participants will receive folic acid \>= 5 mg/week or equivalent.

Summary
Brief summary
This study will assess the long-term safety and efficacy of repeat treatment courses of rituximab, in combination with methotrexate in a disease-modifying anti-rheumatic drug (DMARD) inadequate responder population of participants who were previously randomized into studies WA16291 (NCT02693210) or WA17043/U2644g (NCT00074438). The study permits multiple re-treatments until the protocol-defined end-of-treatment date (31 December 2011). Participants will then enter a safety follow-up (SFU) period of at least 48 weeks. This will provide at least 7 years follow-up data on all participants initially randomized into WA16291 or WA17043/U2644g. Approximately 600 participants will potentially be eligible to enter this open label extension study from their respective feeder studies.
