The purpose of this study is to evaluate the risk of getting lymphoma if you have rheumatoid arthritis and/or Crohns disease and you have taken infliximab.
|Study Design:||Time Perspective: Retrospective|
|Official Title:||A Review of Reports of Lymphoma Occurring in Patients With Rheumatoid Arthritis or Crohn's Disease in Centocor-Sponsored and Centocor-Supported Disease Registries|
|Study Start Date:||June 2006|
|Study Completion Date:||August 2006|
This is an observational (review of records), retrospective (research activity that is performed after the events under the study have occurred), registry study where data was collected from 3 different registries sponsored or supported by Centocor. A registry is data collection in a real life physician-patient setting. Physicians prescribe medications for rheumatoid arthritis and/or Crohns disease in accordance with their usual clinical practice and then record this information and provide it to Centocor. For this registry study, Centocor collected data from 3 registries to evaluate the risk of getting lymphoma if you have rheumatoid arthritis and/or Crohns disease and you have taken infliximab. Patients that were in one of the 3 registries and had rheumatoid arthritis and/or Crohns disease and did NOT take infliximab were also evaluated. This registry study does not involve the use of any investigational drugs, and the protocol does not mandate the treatment regimen the patients will receive.
