CAMBRIDGE, Mass.–(BUSINESS WIRE) April 10, 2024 — Amylyx Prescribed drugs, Inc. (NASDAQ: AMLX) (“Amylyx” or the “Firm”) immediately introduced interim information from the continued Part 2 HELIOS scientific trial of AMX0035 (sodium phenylbutyrate [PB] and taurursodiol [TURSO, also known as ursodoxicoltaurine]) in adults dwelling with Wolfram syndrome, a uncommon, progressive genetic illness impacting roughly 3,000 individuals within the U.S. The interim information from eight members who’ve accomplished 24 weeks of remedy demonstrated that AMX0035 had a clinically significant impact on key outcomes measuring the development of diabetes, visible decline, and total illness burden in grownup members dwelling with Wolfram syndrome.
“I’ve been finding out Wolfram syndrome and caring for individuals with the illness for greater than 20 years. This neighborhood has an pressing unmet want for illness modifying therapies. Outcomes for individuals with Wolfram syndrome constantly worsen over time, so illness stabilization alone is clinically significant for each sufferers and their docs. The interim outcomes from HELIOS that show enchancment throughout a number of organ methods impacted by this progressive illness are encouraging,” mentioned Fumihiko Urano, MD, PhD, Principal Investigator of the Part 2 HELIOS scientific trial in Wolfram syndrome and the Samuel E. Schechter Professor of Drugs within the Division of Endocrinology, Metabolism & Lipid Analysis at Washington College Faculty of Drugs in St. Louis.
HELIOS is an ongoing, open-label Part 2 examine in 12 members designed to judge if AMX0035 slows development of diabetic, visible, and different measures in individuals dwelling with Wolfram syndrome and to judge security and tolerability. The first efficacy endpoint of the trial measures change from baseline in C-peptide, a longtime, goal laboratory measure of pancreatic beta cell perform and glycemic management, assessed utilizing a Combined Meal Tolerance Take a look at (MMTT). Secondary and exploratory outcomes embody the measurement of different diabetic responses and different domains affected by the illness. The interim evaluation carried out relies on a knowledge cutoff as of March 5, 2024, which incorporates all members who accomplished their Week 24 assessments as of the cutoff (n=8).
On this interim evaluation of eight members handled with AMX0035, will increase had been noticed on common within the major consequence of whole C-peptide response (C-peptide AUC change from baseline) together with within the 90-minute response at Week 24 (+15.6 ng*min/mL, 95% CI: [1.3, 30.0]). In Wolfram syndrome, progressive decline would have been anticipated on this measure. Moreover, seven out of eight members demonstrated at the least a 30-minute shorter time to peak C-peptide response. In Wolfram syndrome, a progressive enhance in time to peak C-peptide response, indicating slower pancreatic response, and lowered whole C-peptide response would have been anticipated.
“The enhancements in C-peptide, an goal laboratory measure, noticed in our HELIOS trial are promising and differ from the conventional course of Wolfram syndrome regardless of finest supportive care,” mentioned Camille L. Bedrosian, MD, Chief Medical Officer of Amylyx. “Nearly all of individuals with Wolfram syndrome carry mutations within the WFS1 gene, which encodes a protein that spans the membrane of the endoplasmic reticulum (ER) known as wolframin. Lack of wolframin perform results in ER stress and impaired mitochondrial dynamics, which in flip results in dysfunction and apoptosis of cells. Due to the clear hyperlink between WFS1 mutations and ER stress, Wolfram syndrome is taken into account a prototypical ER stress dysfunction. AMX0035 is believed to focus on each ER stress and mitochondrial dysfunction. We imagine immediately’s interim outcomes help the compelling science behind the mechanism of motion of AMX0035 and its potential to assist individuals dwelling with Wolfram syndrome.”
“The HELIOS trial started because of a multi-year collaboration with the Wolfram syndrome neighborhood and follows robust preclinical information with clear results in mobile and animal fashions. We thank the Wolfram neighborhood, together with these taking part in HELIOS, their family members, and the scientific employees at Washington College Faculty of Drugs in St. Louis, for his or her help of this essential trial,” mentioned Justin Klee and Joshua Cohen, Co-CEOs of Amylyx. “We’re planning to interact with regulatory authorities to align on the event path in Wolfram syndrome. We anticipate topline information for all 12 members at Week 24 within the second half of this 12 months.”
The next consists of further key information from the interim evaluation:
- Hemoglobin A1C (HbA1c) is a measure of glycosylated hemoglobin which serves as a metric of how nicely sugar ranges are being managed within the blood. HbA1c was lowered by 0.26% (SE: 0.15%) on common after 24-weeks of AMX0035 remedy with six out of eight members displaying enchancment of their HbA1c. Many research have related lowered HbA1c with higher scientific outcomes.
- All members had steady glucose monitoring within the examine permitting for a rigorous measurement of the time in goal glucose vary. Absolutely the time in goal glucose vary improved on common by +7.1% (SE: 4.7%). 5 out of eight members had enhancements within the time in goal glucose vary. Elevated time in goal glucose vary is related to higher diabetic outcomes.
- Visible acuity was measured by the Snellen chart. Wolfram syndrome ends in progressive optic nerve atrophy resulting in relentless lack of each visible acuity and coloration imaginative and prescient, and ultimately blindness. On common in HELIOS, visible acuity improved +0.05 -LogMAR (SE: 0.09) with 5 out of eight members demonstrating some enchancment in imaginative and prescient. Of those that improved, one participant modified from legally blind to legally sighted. Optical coherence tomography outcomes haven’t but been assessed and shall be included in last information evaluation from HELIOS.
- All members (8 out of 8) confirmed illness stability or enchancment at Week 24, as measured by The Clinician Report World Impression of Change (CGIC) and Affected person Reported World Impression of Change (PGIC). Enchancment was famous by the CGIC in 62.5% of circumstances (5 out of 8) and by the PGIC for 75% of circumstances (6 out of 8) with the rest reporting illness stability on each the CGIC and PGIC. These consequence measures are designed to report if the general burden of illness has improved, stayed the identical, or worsened from the clinician’s or affected person’s perspective.
- The protection profile of AMX0035 in HELIOS was in keeping with prior security information. AMX0035 was usually well-tolerated. Nearly all of adversarial occasions (AEs) had been gentle or reasonable, and there have been no severe AEs associated to AMX0035 remedy. The most typical AE was diarrhea.
In September 2022, researchers from Washington College Faculty of Drugs in St. Louis, together with Dr. Urano, in collaboration with Amylyx, printed constructive preclinical information on AMX0035 in beta cell, neuronal cell and mouse fashions of Wolfram syndrome within the peer-reviewed Journal of Scientific Investigation Perception. Amylyx introduced that the FDA granted orphan drug designation to AMX0035 for the remedy of Wolfram syndrome in November 2020.
About AMX0035
AMX0035 is an oral, fixed-dose mixture of sodium phenylbutyrate (PB) and taurursodiol (TURSO; also called ursodoxicoltaurine outdoors of the U.S.). AMX0035 was designed to gradual or mitigate neurodegeneration by focusing on endoplasmic reticulum (ER) stress and mitochondrial dysfunction, two related central pathways that result in cell loss of life and neurodegeneration. Preclinical research have supplied proof that AMX0035 could cut back cell loss of life and enhance mobile perform, additionally supporting the synergistic impact of AMX0035 in comparison with particular person compounds. AMX0035 is being studied as a possible remedy in neurodegenerative ailments, together with Wolfram syndrome and progressive supranuclear palsy (PSP).
In regards to the HELIOS Trial
The HELIOS trial (NCT05676034) is a 12-participant, open-label Part 2 trial designed to review the impact of AMX0035 on security and tolerability, and varied measures of endocrinological, neurological, and ophthalmologic perform in grownup members dwelling with Wolfram syndrome.
About Wolfram Syndrome
Wolfram syndrome is an autosomal recessive neurodegenerative illness characterised by childhood-onset diabetes, optic nerve atrophy, and neurodegeneration. Widespread manifestations of Wolfram syndrome embody diabetes mellitus, optic nerve atrophy, central diabetes insipidus, sensorineural deafness, neurogenic bladder, and progressive neurologic difficulties. Literature suggests roughly 3,000 persons are dwelling with Wolfram syndrome in the USA.1 Genetic and experimental proof means that endoplasmic reticulum (ER) dysfunction is a important pathogenic part of Wolfram syndrome. The prognosis of Wolfram syndrome is poor, and many individuals with the illness die prematurely with extreme neurological disabilities.
