BIOGEN COVID-19 INFORMATION CENTER. Thank you to the many front-line workers and organizations working tirelessly to help in these difficult days. Please find updates on Biogen’s response to COVID-19 here.

Welcome to Biogen Trial Link.

Connecting you with clinical trials.

If you or a loved one is ill or battling with a long-term condition, you’ll know just how physically and emotionally challenging such fights can be.

At Biogen, our mission is to discover, develop and deliver innovative therapies that improve the lives of patients around the world. That’s why we conduct clinical trials.

Each individual who participates in our clinical trials contributes to our understanding of the disease and has the potential to benefit patients around the world.

For more information on Biogen clinical trials, please visit our clinical research area sections below, or our Clinical Trial Transparency and Data Sharing website

Alzheimer’s Disease

We are working with the goal of meaningfully changing the course of Alzheimer’s disease and working with the goal of improving the lives of Alzheimer’s patients and their loved ones.

Amyotrophic Lateral Sclerosis (ALS)

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that results in the loss of motor neurons in the brain and the spinal cord.

Brain Contusion

Brain contusions (bleeding and surrounding swelling within the brain) are a devastating complication associated with blunt head trauma.


Systemic lupus erythematosus is a chronic inflammatory disease that occurs when the body’s own immune system mistakenly attacks healthy tissue in skin, joints, kidneys, the brain, and other organs.

Multiple Sclerosis

Biogen has pioneered, and been committed to, research and development in multiple sclerosis (MS) for more than 25 years. We’ve come a long way, but there is still no cure for the millions of people around the world living with MS. That’s why we continue to innovate – with the goal of helping advance treatment and improving outcomes.

Multiple System Atrophy (MSA)

Multiple system atrophy (MSA) is a rare, rapidly progressive, ultimately fatal disorder of the central nervous system.


X-linked Retinitis Pigmentosa (XLRP) caused by mutations in RPGR gene is a form of retinitis pigmentosa, a rare inherited retinal disorder.


Trigeminal neuralgia is an extremely painful rare condition usually involving one side of the face. Small fiber neuropathy (SFN) is a condition characterized by severe pain attacks that typically begin in the feet or hands.

Parkinson’s Disease

Parkinson’s is a life-changing disease that brings with it many uncertainties about the future. Getting involved in a clinical research trial can be a way of taking positive action and contributing to potential future breakthroughs in this often-unpredictable disease.


Of those people living with schizophrenia it is estimated that the majority of them live with some degree of cognitive impairment. When cognition is impaired, processing information, planning, and remembering become difficult or impossible.

Spinal Muscular Atrophy (SMA)

SMA is a genetic, progressive and often terminal rare disease that affects an individual’s ability to walk, eat, and ultimately, breathe.


Large hemispheric infarction (LHI) is a severe form of ischemic stroke where brain swelling (cerebral edema) often leads to a disproportionately large share of stroke related morbidity and mortality.

What other clinical indications is Biogen working in?

We are working in clinical indications (disease areas) beyond those listed above, so please get in touch if you want to know about any of our other clinical trials.
