We Have One Mission
End ALS.
We are the world's most comprehensive drug discovery lab focused solely on ALS.
We are a drug discovery engine helping treatments get to trials.
As a nonprofit, our cutting-edge research is funded
by a global community united in ending ALS.
This is Your Lab
As you read this, our team of researchers and scientists are urgently working in our Boston-area lab – screening drugs, studying animal models, and collecting and analyzing data from people with ALS. ALS is complex, and the science is complicated, but we are relentless. We will not stop until we have treatments for everyone living with ALS.
“I support ALS TDI because not only is their focus on ALS research and finding a treatment, but ALS TDI focuses on the ALS community, those actually living with the disease. ALS TDI understands the urgency that people with ALS live with in finding a treatment and is driven by that urgency.”

“ALS TDI is one of the world's most transformative medical research institutes focused on ALS. We have applied business principles with the leadership of Dr. Fernando Vieira to find a cure for ALS! I am proud to lead that effort as its Chairman.”

Fueled By the Community

As a nonprofit, we are only answerable to our supporters, the ALS community. Our research is funded by the ALS community, a global network of supporters whose lives have been affected by this disease, and who are unified to end ALS. We're getting closer, but we need your help.
Making An Impact

Making An Impact

Our science team invented AT-1501, a promising treatment for ALS that is currently in trials. We also innovated the first ALS Precision Medicine Program to discover more potential treatments faster. Our team is working urgently to identify more potential treatments and have them made available for people with ALS.
