CAMBRIDGE, MASS.--(BUSINESS WIRE)--
Amylyx Pharmaceuticals, Inc., a pharmaceutical company focused on developing new treatments for amyotrophic lateral sclerosis (ALS), Alzheimer’s disease and other neurodegenerative diseases, today announced it has completed enrollment in the Phase II PEGASUS trial assessing AMX0035 in individuals with Alzheimer’s disease. Amylyx completed enrollment, dosing 96 of the previously planned 100 participants.
The PEGASUS trial will provide data on the safety and tolerability profile of AMX0035 in people living with Alzheimer’s disease, biological activity on biomarkers related to disease processes and preliminary information on cognitive and functional effects of AMX0035. Trial collaborators include the Alzheimer’s Association, the Alzheimer’s Drug Discovery Foundation (ADDF) and Cure Alzheimer’s Fund.
In April 2019, Amylyx doubled the PEGASUS trial’s planned enrollment to approximately 100 participants with additional funding support from Cure’s Alzheimer’s Fund. The trial was first supported in 2017 through the Alzheimer’s Combination Therapy Opportunities (ACTO) program, a joint research funding initiative created by the Alzheimer’s Association and the ADDF.
“Alzheimer’s disease is a complex, progressive brain disorder with no disease-modifying treatments that impact the neurodegenerative process,” said Steven E. Arnold, M.D., Translational Neurology Head of the Interdisciplinary Brain Center at Massachusetts General Hospital and Harvard Medical School and the PEGASUS trial’s principal investigator. “Due to COVID-19, we must pay close attention to the safety of older adults whose associated health conditions and age may pose a risk. We are pressing ahead safely as we expect the trial will generate meaningful insights about the ability of AMX0035 to target mechanisms involved in the progression of Alzheimer’s.”
Patient safety is Amylyx’ priority. In an effort to mitigate possible delays due to the coronavirus pandemic, multiple steps have been taken in the PEGASUS trial to reduce patient exposure. Amylyx has worked with clinicians to switch to virtual visits and expand clinic visitation windows when possible. Amylyx also capped trial enrollment early at 96 to ensure patient safety and to responsibly respond to clinical trial site closures. Topline data remain targeted for early 2021.
“Alzheimer’s disease remains one of the most critically unmet needs in healthcare and we desperately need new treatments for patients,” said Rudolph Tanzi, Ph.D., Kennedy Professor of Neurology, Massachusetts General Hospital and Harvard Medical School, chair of the Amylyx Scientific Advisory Board and chair of the Cure Alzheimer’s Fund Research Leadership Group. “AMX0035 recently showed benefit in patients with ALS, and the same mechanism of neuroprotection may also be helpful in Alzheimer’s disease. We are very fortunate that the PEGASUS trial has continued, despite COVID-19, and eagerly await data in Q1 2021.”
Last year, Amylyx announced that AMX0035 met its clinical endpoint in the CENTAUR study in people with ALS. In the study, participants taking AMX0035 had a statistically significant slowing of ALS disease progression as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R) compared to placebo (p<0.05), the primary efficacy outcome of the trial. Detailed results from this study will be published shortly.
“We deeply appreciate the participation from patients and their families and the support we have received, particularly as we address new challenges during this global crisis,” said Kent Leslie, Chief Scientific Officer at Amylyx. “We remain committed to those battling Alzheimer’s disease and to the research that will propel us to bring timely answers to the community later this year. Thank you to the patients, investigators, site teams, Alzheimer’s Association, Alzheimer’s Drug Discovery Foundation and Cure Alzheimer’s Fund whose rigor and dedication make this trial possible.”
PEGASUS (NCT03533257) is a 3:2 randomized, double-blind, multi-center, placebo-controlled study evaluating the safety, tolerability and activity of AMX0035 in patients with late mild cognitive impairment or early dementia due to Alzheimer’s disease over 24 weeks. The biomarker-focused trial design will assist in understanding the effects of AMX0035 and its potential in treating Alzheimer’s disease.
AMX0035 is a first-in-class investigational therapy designed to reduce neuronal death and dysfunction. AMX0035 targets mitochondrial and endoplasmic reticulum-dependent neuronal degeneration pathways.
