The Canadian Neuromuscular Disease Registry and Amylyx Pharmaceuticals Partner on Real-World Evidence Generation for a Novel Investigational Therapy in ALS with the Goal of Advancing Health Outcomes for Canadians Living with ALS

February 3, 2022 at 9:00 PM EST

CALGARY, Alberta & TORONTO--(BUSINESS WIRE)-- The Canadian Neuromuscular Disease Registry (CNDR), an independent, academic registry based out of the University of Calgary, and Amylyx Pharmaceuticals (NASDAQ: AMLX) today announced they are partnering on a real‐world evidence generation initiative for Amylyx’ novel investigational therapy AMX0035 (sodium phenylbutyrate (PB) and ursodoxicoltaurine (TURSO; also known as taurursodiol)), for the treatment of amyotrophic lateral sclerosis (ALS).

The CNDR’s principal investigator, Dr. Lawrence Korngut, in collaboration with co-principal investigators, Drs. Agessandro Abrahao and Lorne Zinman from the Sunnybrook Health Science Centre and the University of Toronto, will partner with neuromuscular centers across Canada, including the pan-provincial ALS clinics that are part of the Canadian ALS Research Network (CALS), to follow consenting participants and collect key demographic, clinical, functional and survival data related to people living with ALS taking AMX0035. The CNDR-Amylyx partnership has the potential to generate the first global real‐world evidence on AMX0035 for scientific dissemination.

“We believe this collaboration, which brings together the real‐world data capability of the CNDR and the industry expertise of Amylyx Pharmaceuticals, will provide an opportunity for Canadians living with ALS and their loved ones to gain important insights on the impact of AMX0035,” said Dr. Lawrence Korngut. “The advantage of CNDR is that it enables the generation of real‐world evidence for decision‐making, while prioritizing patient treatment and access to investigational therapy. We hope that with this partnership, we can provide insights and guidance for best practices in ALS treatment.”

The ALS Society of Canada welcomes today’s announcement as an important step forward for the ALS community.

“Introducing new investigational therapies for people living with ALS in a timely manner is critical, however we need to better understand how patients respond to investigational therapies in a real‐world context,” said Tammy Moore, CEO of the ALS Society of Canada. “Collaborations between industry and academia are important to ensure that Canadians living with ALS have timely access to the best possible evidence‐based treatments. This partnership could also lay the framework for the timely introduction of future ALS therapies.”

“This investment and partnership with the CNDR is an extension of our long‐standing commitment to the ALS community, as we continue to uncover the full potential of AMX0035 for the benefit of people living with ALS around the world and their loved ones,” said Joshua Cohen, Co‐CEO, Chairman and Co‐Founder of Amylyx.

Justin Klee, Co‐CEO, Director and Co‐Founder of Amylyx added, “Canada has been the site of many first milestones for Amylyx, from setting up a manufacturing partnership in Ontario, to filing the first new drug submission with Health Canada to bring AMX0035 to Canadians living with ALS, and now, this unique collaboration with the CNDR. While this partnership gets underway, we will continue to work expeditiously through the Canadian approval processes required by federal, provincial and territorial governments.”

ABOUT AMX0035

AMX0035 is a proprietary oral fixed-dose combination of two small molecules: sodium phenylbutyrate (PB), which is a small molecular chaperone designed to reduce the unfolded protein response (UPR), preventing cell death resulting from the UPR, and ursodoxicoltaurine (TURSO; also known as taurursodiol), which is a Bax inhibitor designed to reduce cell death through apoptosis. PB and TURSO were combined in a fixed-dose formulation in an effort to reduce neuronal death and dysfunction. AMX0035 is designed to target the endoplasmic reticulum and mitochondrial-dependent neuronal degeneration pathways in ALS and other neurodegenerative diseases.
