Schechter Professor of Medicine in the Division of Endocrinology, Metabolism & Lipid Research at Washington University School of Medicine in St. Louis (WashU Medicine), to discuss topline results from HELIOS, a Phase 2 trial of AMX0035 (sodium phenylbutyrate [PB] and taurursodiol [TURSO, also known as ursodoxicoltaurine]) for the investigational treatment of Wolfram syndrome. The live webcast follows the presentation of these data at the International Society for Pediatric and Adolescent Diabetes 50^th Annual Congress in Lisbon, Portugal.

Dr. Fumihiko Urano is a physician and leading medical researcher at WashU Medicine in St. Louis specializing in the study of Wolfram syndrome and related disorders, including WFS1-related disorders/Wolfram-like disorders. As director of the Wolfram Syndrome Clinic and the Wolfram Syndrome International Registry & Clinical Study at Washington University, Dr. Urano treats patients and leads basic science, clinical, translational, and interventional studies of Wolfram syndrome and related disorders.

About the HELIOS Trial
The HELIOS trial (NCT05676034) is a 12-participant, open-label, proof of biology, Phase 2 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 Wolfram syndrome.

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

About AMX0035
AMX0035 is an oral, fixed-dose combination of sodium phenylbutyrate (PB) and taurursodiol (TURSO; also known as ursodoxicoltaurine outside of the U.S.). AMX0035 was designed to slow or mitigate neurodegeneration by targeting endoplasmic reticulum (ER) stress and mitochondrial dysfunction, two connected central pathways that lead to cell death and neurodegeneration. We believe that our proprietary combination of PB and TURSO and their complementary mechanisms of action will allow us to synergistically target abnormal cell death to better prevent neurodegeneration than treatment targeted at either mechanism of action alone. AMX0035 is being studied as a potential treatment for Wolfram syndrome and progressive supranuclear palsy, two neurodegenerative diseases.
