sharing information
about our clinical
research with patients
and researchers to
improve public health

Our transparency and data sharing policy

In alignment with global legal requirements, the Industry Trade Association Principles1, and internal company policies, Biogen is committed to sharing information about our clinical research as follows:

Clinical trial registration

We register all interventional trials conducted in patients (phase I–IV) initiated after 01 Jan 2005, prior to trial initiation on www.clinicaltrials.gov,  and comply with other international and national clinical trial disclosure requirements.

Clinical trial results summaries

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.

Publication of clinical trial results

We submit the results of all phase 3 clinical trials, and any clinical trial results of significant medical importance, for publication in peer-reviewed journals or at scientific meetings.

Enhancing data sharing with researchers

We commit to share patient-level data, trial-level data, CSRs, and protocols with qualified scientific researchers. Biogen has established a process for researchers to request access to such data from Biogen-sponsored interventional clinical trials conducted in patients (phase I-IV) for products and indications submitted to and approved in both the United States and the European Union, since 2004. Data will be provided to the researcher pending approval of a research proposal and a Data Use/Sharing Agreement signed by the data requestor. 

The research proposal may include enquiries for clinical trials outside of the scope of this policy. In these instances, Biogen will assess feasibility of sharing the data as part of the review process.

Exceptions to Biogen's data sharing policy:

  • Clinical trials where there is a reasonable likelihood that the participant could be re-identified, such as with trials of rare diseases and single-center trials
  • Clinical trials where data sharing is prohibited by the informed consent; or where regulatory, legal, contractual, or other limitations exist
  • Clinical trials where data/documents are not in English
  • Clinical trials where there are ongoing regulatory activities or publication plans

We generally do not share imaging data (e.g. DICOM files of images from x-rays, ultrasounds, MRI scans, etc.) and we will only share genomic data with explicit consent.

For information on the process for submitting a scientific or medical research proposal that includes a request for access to data from Biogen-sponsored clinical research, please visit Vivli. For general enquiries, please contact  datasharing@biogen.com.

Implementation of PhRMA/EFPIA data sharing principles: 

Biogen is committed to implementation of the PhRMA/EFPIA Principles for Responsible Clinical Trial Data Sharing and has established policies and processes to implement these Principles, as of 01 January 2014. The Principles reflect the biopharmaceutical sector’s strong support for responsible data sharing that recognizes the importance of protecting patient privacy, respects the integrity of national regulatory systems, and maintains incentives for continued investment in biopharmaceutical research.

Under the Principles, Biogen, as a PhRMA and EFPIA member company, commits to enhance data sharing with qualified researchers, work with regulators to develop standards for sharing results with the patients who participate in clinical trials, enhance public access to clinical trial information, and reaffirm our commitment to publish clinical trial results.
