We are the world's foremost drug discovery lab focused solely on ALS. Our mission is to discover and develop effective treatments for ALS.

The ALS Therapy Development Institute (ALS TDI) and its researchers discover and develop potential treatments for ALS. It is the world’s first and largest nonprofit biotech focused 100 percent on ALS research. Led by drug development experts and people living with ALS, ALS TDI understands the urgent need to slow and stop this disease.  Based in Cambridge, MA, ALS TDI has over 30 full-time, industry trained, drug development experts on staff. ALS TDI is internationally recognized as a leader in preclinical and translational ALS research, and partners with pharmaceutical companies and biotechs around the world. Rated a four-star nonprofit on Charity Navigator, ALS TDI spends 87 cents of every dollar raised on research to find an effective treatment and cure. ALS is not an incurable disease, it is underfunded. Support us in our mission to end ALS. Learn more at www.als.net.
