Rhea-AI Summary

Amylyx Pharmaceuticals, Inc. (NASDAQ: AMLX) has completed enrollment of its Phase 2 HELIOS trial of AMX0035 for the treatment of Wolfram syndrome, a rare genetic disease with no known cure. Preliminary results are anticipated in the second half of 2024. The trial has enrolled 12 adult participants, and the FDA has granted orphan drug designation to AMX0035 for the treatment of WS, providing potential benefits for the company.

Insights

Medical Research Analyst

The completion of enrollment in Amylyx Pharmaceuticals' Phase 2 HELIOS trial represents a significant milestone in the development of AMX0035 for Wolfram syndrome (WS). WS is an orphan disease, characterized by low prevalence and high unmet medical need. The designation of AMX0035 as an orphan drug by the FDA underscores the potential commercial benefits, including financial incentives and exclusivity post-approval, which could enhance the company's return on investment in this area.

From a research perspective, the trial's focus on endocrinological, neurological and ophthalmologic functions is important, as these are key areas affected by WS. The open-label proof of biology design of the trial allows for the early observation of drug effects, which is critical for rare diseases where patient populations are limited. The data generated could be instrumental in determining the viability of AMX0035 as a treatment option and guiding future research and development efforts.

Financial Analyst

Investors will likely monitor the progress of the HELIOS trial closely, given the potential financial implications of a successful treatment for WS. A positive outcome could lead to a significant market opportunity for Amylyx, considering the orphan drug designation and associated market exclusivity. However, the small patient population limits the market size, which could affect the overall revenue potential for AMX0035.

It is also worth noting that the preliminary results are not expected until the second half of 2024, which introduces a time horizon for investors to consider. The long-term nature of biopharmaceutical development and the inherent risks associated with clinical trials should be factored into any investment analysis. Furthermore, the performance of Amylyx's stock (NASDAQ: AMLX) may reflect investor sentiment regarding the progress and potential outcomes of the HELIOS trial.

Biotech Industry Analyst

For the biotech industry, the development of AMX0035 could set a precedent for the treatment of rare genetic diseases like WS. The successful advancement from preclinical findings to clinical trials highlights the importance of translational research in addressing unmet medical needs. Additionally, the collaboration between academic institutions and biotech companies exemplifies a model for future research endeavors in rare diseases.

The orphan drug designation is a key factor in the biotech industry, as it provides incentives that make the development of treatments for rare diseases more viable. Should AMX0035 prove effective, it could encourage further investment in orphan drug research and development, potentially leading to innovation in the treatment of other rare conditions.

Preliminary results from HELIOS anticipated in the second half of 2024

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Amylyx Pharmaceuticals, Inc. (NASDAQ: AMLX) (“Amylyx” or the “Company”) today announced it has completed enrollment of its Phase 2 HELIOS trial of AMX0035 (sodium phenylbutyrate [PB] and taurursodiol [TURSO]) for the treatment of Wolfram syndrome (WS), a rare genetic disease that typically results in neurodegeneration and premature death, which has no known cure. The trial has enrolled 12 adult participants living with WS, and preliminary results are anticipated in the second half of 2024.

“The unmet need for people living with WS remains significant. WS is progressive, often fatal, and difficult to diagnose, with current treatments focused mostly on helping to address symptoms,” said Fumihiko Urano, MD, PhD, Principal Investigator of the HELIOS clinical trial and Professor of Medicine in the Division of Endocrinology, Metabolism & Lipid Research at Washington University School of Medicine. “Our preclinical findings showed that AMX0035 may impact relevant WS disease pathways and manifestations, and we look forward to the preliminary results from HELIOS anticipated later this year.”

HELIOS is an open-label proof of biology trial designed to study the effect of AMX0035 on safety and tolerability, and various measures of endocrinological, neurological, and ophthalmologic function in adult participants living with WS. Data from this initial study will inform potential future Amylyx trials for individuals with WS.

More information on the HELIOS clinical study can be found at www.clinicaltrials.gov, NCT05676034.

In September 2022, researchers from Washington University School of Medicine in St. Louis, in collaboration with Amylyx, published preclinical data in the peer-reviewed Journal of Clinical Investigation Insight. The data explored the potential of AMX0035 as a novel therapeutic approach for WS and provided initial proof-of-concept for its therapeutic development in WS.

“Little progress has been made in the treatment of WS, and we are excited by the potential we have been seeing in the preclinical work with AMX0035,” said Camille L. Bedrosian, MD, Chief Medical Officer of Amylyx. “These preclinical findings suggest the possibilities of AMX0035 for individuals with WS that we continue to explore, including in the HELIOS trial. We are grateful to those who partnered to complete this important clinical trial enrollment milestone, in particular, the WS community, their families and caregivers, experts, clinicians, researchers, and advocacy leaders.”

Amylyx announced that the FDA granted orphan drug designation to AMX0035 for the treatment of WS in November 2020. The FDA may grant this designation to drugs and biologics intended to treat a rare disease or condition affecting fewer than 200,000 persons in the U.S. Orphan designation qualifies a company for certain benefits, including financial incentives to support clinical development and the potential for seven years of market exclusivity in the U.S. upon regulatory approval.

About Wolfram Syndrome

Wolfram syndrome (WS) is an autosomal recessive neurodegenerative disease characterized by childhood-onset diabetes, optic nerve atrophy, and neurodegeneration. Common manifestations of WS include diabetes mellitus, optic nerve atrophy, central diabetes insipidus, sensorineural deafness, neurogenic bladder, and progressive neurologic difficulties. Genetic and experimental evidence suggest that endoplasmic reticulum (ER) dysfunction is a critical pathogenic component of WS. The prognosis of WS is poor, and many people with the disease die prematurely with severe neurological disabilities.

About AMX0035 / RELYVRIO^®/ ALBRIOZA™ / ALBRIOZA^®

AMX0035 is an oral, fixed-dose combination of sodium phenylbutyrate and taurursodiol (known as ursodoxicoltaurine outside of the U.S.). It is approved as RELYVRIO^® to treat amyotrophic lateral sclerosis (ALS) in adults in the U.S. and approved with conditions as ALBRIOZA™ for the treatment of ALS in Canada. AMX0035 is being studied for the potential treatment of other neurodegenerative diseases, and Amylyx is exploring its treatment in other populations and regions. The formulation of RELYVRIO, ALBRIOZA, and AMX0035 is identical.
