Amylyx Plummets as ALS Drug Fails to Benefit Patients

The journey to bring new, potentially life-saving drugs to the market can be fraught with hurdles and disappointments. This is a tale that biopharmaceutical company Amylyx knows all too well, especially concerning its drug Relyvrio, aimed at tackling Amyotrophic Lateral Sclerosis (ALS)—a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.

The regulatory journey for Amylyx and Relyvrio, the company’s sole drug contender for ALS, has been particularly arduous in the United States. Initial excitement waned in March 2022 when FDA advisers concluded that the evidence, rooted in a small-scale study by the company, fell short of conclusively demonstrating the drug’s ability to slow the progression of ALS. This verdict came as a blow to the hopes pinned on Relyvrio, which, if verified, would have marked a significant advancement in ALS therapy.

Despite the setback, a rare second chance was afforded later that year when a second panel meeting convened. Armed with additional data from Amylyx, the advisory panel shifted its stance and ultimately supported the drug’s approval. This outcome underscored the dynamic and often unpredictable nature of the drug approval process, highlighting the complexities involved in bringing new therapies to market.

In a parallel development, Canadian health regulators opted for a cautious approach by granting conditional approval to Relyvrio. This allowed for the drug’s availability on the market, albeit with the provision for its withdrawal should subsequent clinical trials not yield favorable results. In contrast, the FDA opted for full approval of Relyvrio in the US, a decision that now places the agency in a challenging position in light of recent developments.

The crux of the matter lies in the outcomes of the follow-up clinical trial. Amylyx had committed to withdrawing Relyvrio from the US market should this crucial trial falter. Given the trial’s disappointing results—specifically, its failure to demonstrate patient benefits—the company now stands at a crossroads, with significant implications for both its operations and the wider ALS community.

Notwithstanding these challenges, Amylyx remains resolute in its mission to serve those battling ALS. The company’s leadership, Co-chief Executive Officers Justin Klee and Joshua Cohen, have expressed their intention to continue dialogues with regulatory authorities and the ALS community. “We will be led in our decisions by two key principles: doing what is right for people living with ALS, informed by regulatory authorities and the ALS community, and by what the science tells us,” they affirmed in a statement.

This commitment reflects the company’s dedication to navigating the complex regulatory landscape and underscores the broader struggle faced by pharmaceutical companies in their quest to bring innovative treatments to market. The unfolding story of Relyvrio serves as a poignant reminder of the hurdles inherent in the path to drug approval, the unpredictability of clinical trials, and the profound impact of these processes on patients clinging to hope for effective treatment options.
