Trial results summaries for completed Biogen-sponsored clinical trials in patients are disclosed on local websites in compliance with international and national clinical trial disclosure requirements. In addition, we disclose trial results summaries for interventional trials conducted in patients (phase I-IV) completed after 01 Jan 2005, for approved products commercially available in at least one country, as well as for those products discontinued in development. Trial results are disclosed on this website using one or more of the following methods:

Posted publicly on a national website, such as www.clinicaltrials.gov and www.clinicaltrialsregister.eu, according to required timelines

Published in a peer-reviewed journal or at a scientific meeting

Posted publicly as a Clinical Study Report (CSR) Synopsis

We further commit to publicly post CSR synopses on this website for products and indications submitted to and approved in both the United States and the European Union, after 01 January 2014.
CSR synopses will be redacted consistent with the need to protect privacy, publication rights, and confidential commercial information.Result summaries are available within one year of the initial product approval or, for post-approval trials, within one year of trial completion. When a product in development has been discontinued, results of all interventional trials conducted in patients (phase I-IV) are disclosed on this website within one year of its discontinuation.
We are also committed to sharing trial results summaries in a format that is easy to read and understand. These summaries, often referred to as plain or lay language results summaries, are posted publicly on this website for interventional trials conducted in patients (phase I - IV) or where required as per international disclosure requirements.
