Amylyx Pharmaceuticals Announces First Patients Dosed in PEGASUS Phase 2 Trial of AMX0035 in Alzheimer’s Disease and Expansion of the Trial

April 3, 2019 Off By BusinessWire

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Amylyx Pharmaceuticals, Inc., in collaboration with the Alzheimer’s
Association, the Alzheimer’s Drug Discovery Foundation (ADDF) and the
Cure Alzheimer’s Fund, today announced the dosing of its first patients
in a recently expanded Phase 2 clinical trial (PEGASUS) to assess
AMX0035 in individuals with Alzheimer’s disease. AMX0035 is Amylyx’s
proprietary two-drug combination therapy in development to prevent nerve
cell death and degeneration.

“The urgent need for a new approach to Alzheimer’s is clearer now than
ever. As this is one of the first major combination therapy clinical
trials for Alzheimer’s Disease, we’re optimistic about AMX0035’s
potential to slow disease progression in individuals through its novel
mechanisms of action,” said Steven E. Arnold, M.D., Translational
Neurology Head of the Interdisciplinary Brain Center at Massachusetts
General Hospital and Harvard Medical School and the study’s principal
investigator.

Alzheimer’s is a complex disease that likely has multiple, interrelated
causes. A growing number of experts believe combination therapy—with
multiple therapeutics—will be required to effectively treat it.

“Although targeting the classic pathologies of Alzheimer’s disease,
beta-amyloid and tau, has proven challenging in clinical trials, this
research has awarded us with a wealth of knowledge in our understanding
of the disease,” said Rudolph Tanzi, Ph.D., of Massachusetts General
Hospital, chair of the Cure Alzheimer’s Fund Research Leadership Group
and chair of the Amylyx SAB. “Cure Alzheimer’s Fund is proud to take
initiative and provide additional funding to expand Amylyx’s trial to
support the development of novel approaches that patients need,” Dr.
Tanzi added.

With additional funding from the Cure’s Alzheimer’s Fund, the PEGASUS
trial has doubled its planned enrollment to 100 participants, with 20
patients enrolled and dosed to date. 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 to support clinical trials combining multiple
treatment approaches.

“There have been trials targeting amyloid, and there have been trials
targeting tau, but this is the first trial to target two novel
mechanisms in tandem,” said Howard Fillit, M.D., the ADDF’s founding
executive director and chief science officer. “The ADDF was one of the
earliest supporters of innovative targets for Alzheimer’s, and we
believe combination therapies are a critical next step in finding
effective treatments for the disease.”

“The rationale for combination therapies has already been demonstrated
in diseases like HIV/AIDS, cancer and heart disease. We believe this
type of approach will also work for Alzheimer’s and other dementias and
are encouraged by the launch of this combination therapy trial,” said
Maria C. Carrillo, Ph.D., Alzheimer’s Association’s chief science
officer. “The Alzheimer’s Association is honored to be at the forefront
of the mission to keep expanding the research pipeline for therapies
that attack this complex disease from a variety of angles.”

PEGASUS 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 demonstrating the effects
of AMX0035 and its potential in treating Alzheimer’s disease. Study
results are expected in 2020.

“We believe AMX0035 has potential across multiple neurodegenerative
diseases. We’re moving quickly to determine the synergistic efficacy of
these two therapies and deeply value the support from the Alzheimer’s
Drug Discovery Foundation (ADDF), the Alzheimer’s Association and the
Cure Alzheimer’s Fund to expand this unique trial,” said Kent Leslie,
Amylyx’s chief scientific officer.
