The BSR commissioned the BSRBR-RA as a UK-wide national project to investigate the safety of biologic agents in routine medical practice. BSR receives restricted income from UK pharmaceutical companies, presently Abbott Laboratories, Merck, Pfizer, Roche, UCB and SOBI. This income finances a wholly separate contract between the BSR and the University of Manchester who provide and oversee the BSRBR-RA data collection, management and analysis service. The principal investigators and their team have full academic freedom and are able to work independently of pharmaceutical industry influence.
