A Patient Perspective on ALS Clinical Trials and Timely Access

When time matters, how much evidence is enough?

How much evidence should be required before people living with ALS can access a promising new therapy?

In a newly published Reader Response in Neurology, Dr. Andrew Darke, an ALS Action Canada Advocacy Committee Member, responds to a recent article examining what its authors describe as a “credibility gap” in ALS clinical trials, due to what it describes as a “Clinical Trial Industrial Complex” involving ALS neurologists and manufacturers of new drugs for ALS.

Andrew offers an important patient perspective on the role of Phase 2 clinical trial evidence in regulatory decision-making. Using the development and subsequent withdrawal of Albrioza (sodium phenylbutyrate–taurursodiol) as an example, he argues that adequately powered Phase 2 studies, supported by robust statistical analysis, can have an appropriate role in expedited or conditional approval pathways — particularly for ALS and other rare diseases where time matters profoundly to patients.

Andrew’s response represents his individual perspective and contributes to a broader and important discussion about how we balance scientific rigour, uncertainty and the urgent need for new ALS treatments.

Challenging Barriers to ALS Treatment Access: Bringing Our Patient Voice to Canada’s Drug Agency

From time to time, we hear of pALS who are not eligible to get Radicava under their provincial or private insurance plan. Recently we heard of a pALS who had been on Radicava, but were later told they were no longer eligible to receive it. The reason for this is the criteria for who is eligible for drugs, and who can continue to receive them under the provincial drug benefit plans. These criteria are developed by Canada’s Drug Agency (CDA), which is a separate agency from Health Canada which approves drugs as safe and effective
to be marketed.

Patient Perspectives Highlight Importance of Modest ALS Treatment Gains 

Recent pieces published in the international neurology journal, Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration, have sparked debate in the ALS community. 

In ALS Action Canada’s paper (Darke and Orsulak 2025), “How Effective Does a New Drug for Amyotrophic Lateral Sclerosis Need To Be – The Patient Perspective”, we argued against the proposal of Boddy et al (2025).
