Understanding the promise of Albrioza: Q&A with the CEO of ALS Society of Canada

Amyotrophic lateral sclerosis (ALS) remains a bewildering disease. Although it is rare, it is not uncommon. The lifetime risk of developing the condition is roughly 1 in 300 by age 85. 

The heterogeneity of the disease is also unique, said Tammy Pighin Moore, CEO of the ALS Society of Canada. “About 5% to 10% of the people diagnosed with ALS have a familial or hereditary connection to it that we can easily understand because of the genes implicated,” Moore said.  

Symptoms can begin in the limb (known as ‘limb onset’) or first affect speech or swallowing (known as ‘bulbar onset’). Some patients with the disease die months after diagnosis, while others may live for decades. For example, the famed physicist Stephen Hawking lived with the condition for 55 years.

A forthcoming Phase 3 trial will evaluate the safety and efficacy of the drug over 48 weeks. 

Before reversing course, FDA had asked Amylyx to submit positive Phase 3 trial results before filing a New Drug Application.

To date, there are limited treatment options available for ALS. A 2020 paper in Neuropharmacology.
