Kristina, living with ALS

Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive and fatal neurodegenerative disorder caused by motor neuron death in the brain and spinal cord. Motor neuron loss in ALS leads to deteriorating muscle function, the inability to move and speak, respiratory paralysis and eventually, death.1,2 More than 90% of people with ALS have sporadic disease, showing no clear family history.3

We believe that it’s going to take a combination approach, targeting multiple cellular pathways implicated in disease pathogenesis, to find a cure for ALS. For this reason, we are investigating multiple therapies with different or potentially complementary pathways in ALS and other neurodegenerative diseases, in-house and in partnership with leading clinicians and researchers. This includes:

  • Amylyx' development of antisense oligonucleotides (ASOs), including lead ASO AMX0114 aimed at targeting calpain-2 (CAPN2), a gene encoding calcium-dependent proteolytic enzyme and a critical effector of axonal degeneration, which has been implicated in the pathogenesis of ALS and other neurodegenerative diseases.

  • Amylyx' continued commitment to donate clinical trial data to patient registries, such as the PRO-ACT database, to share new information with the research community that could open up new pathways and approaches to developing new treatments. Learn more.
  • In designing our trials, we rely on the input of clinical leaders, advocacy groups, and the neurodegenerative disease community. This collaborative approach keeps people living with neurodegenerative diseases at the center of everything we do and is something we will continue in future trials.

Our commitment

At Amylyx, we are relentlessly driven by a commitment to those living with neurodegenerative diseases. We work collaboratively across everything we do, aspiring to help support and create more moments for the neurodegenerative community.


Our innovative approach to developing transformative therapeutics has far-reaching potential to improve the management of multiple neurodegenerative diseases. Learn more about our growing pipeline.
