Amyotrophic Lateral Sclerosis (ALS)

Rapidly progressing neurodegenerative disease caused by oxidative damage which leads to neuronal cell death and muscular atrophy

What is Amyotrophic Lateral Sclerosis?

Amyotrophic lateral sclerosis, sometimes referred to as ALS, motor neuron disease, or Lou Gehrig’s disease, is a rare, progressive, and fatal neurodegenerative disease that affects motor neurons in the brain and spinal cord.1,2 Amyotrophic lateral sclerosis becomes life-threatening as people with this disease ultimately lose the ability to move, speak, eat, and breathe.1

How common is Amyotrophic Lateral Sclerosis?

Approximately 1.5 to 3 per 100,000 people develop amyotrophic lateral sclerosis every year in North America and Europe, which equates to approximately 5,000-6,000 new cases each year.1,4,5 Men are disproportionately affected at a ratio of 2:1.4,5

How is PTC Working to Treat Amyotrophic Lateral Sclerosis?

Utreloxastat, discovered through PTC’s Bio-e platform, is an investigational small molecule that inhibits 15-Lipoxygenase, an enzyme that is a key regulator of the oxidative stress, protein aggregation and inflammation response pathways that underpin neurodegenerative disease pathology.
