Clinical
Trial Results
At Biogen, we build trust through transparency, sharing clinical trial data to empower patients, researchers, and healthcare professionals, advancing science and patient outcomes.
We're committed to sharing information about our clinical research in alignment with global legal requirements, the industry trade association principles, and internal company policies. Generally, results summaries are available within one year of the initial product approval, or for post approval trials, within one year of the trial completion.
Please refer to Biogen’s transparency & data sharing policy for more information.

Biogen is committed to sharing CSR Synopses and Trial Results Summaries (often referred to as plain language summaries). For US and EU approved products, we post CSR synopses within one year of approval or study completion. For all patient trials, including discontinued studies, we also provide Trial Results Summaries that present the information in clear, easy-to-understand language.
