TORONTO,
ONTARIO, July 13, 2023 – Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZS) (“Aeterna” or the “Company”),
a specialty biopharmaceutical company developing and commercializing a diversified portfolio of pharmaceutical and diagnostic products,
today provided an update on its therapeutic and diagnostic development pipeline programs and outlined upcoming key milestones.
“We
are encouraged by our significant progress across all of our active development programs, and based on the prioritization of our pipeline,
have strengthened our focus on our diagnostic and therapeutic programs as we execute on key decision points,” commented Dr. Klaus
Paulini, Chief Executive Officer of Aeterna. “Additionally, in our ongoing DETECT clinical trial, we are making significant progress
regarding patient recruitment and believe we are well-positioned to continue building momentum towards completion of the study by year’s
end. Further, based upon our active outreach and discussions, we expect to secure an alternate development and commercialization partner
for Macrilen® for the U.S. and Canada.”
Therapeutics
Development Pipeline Update
Autoimmunity
Modifying (“AIM”) Biologicals: Targeted, highly specific autoimmunity modifying fusion proteins for the potential treatment
of neuromyelitis optica spectrum disorder (“NMOSD”) and Parkinson’s disease (“PD”)
AIM
Biologicals represent a unique platform technology with the potential to address the cause and not only the symptoms of auto-immune and
inflammatory, neurodegenerative disorders at early stages. This approach is based on induction of selective and highly target-specific
immune de-sensibilization based on the natural concept of feto-maternal tolerance.
Dr.
Paulini added, “We have received encouraging feedback from our collaborator and scientific advisor on the NMOSD indication, Dr.
Michael Levy, Research Director of the Division of Neuroimmunology & Neuroinfectious Disease at Massachusetts General Hospital. Dr.
Levy shares our vision that presenting antigens on soluble HLA-G fusion proteins is a promising, novel approach to induce antigen specific
immune tolerance among NMOSD and PD patients. Together, we look forward to furthering the development of this program.”
Recent
Highlights
|
● |
Demonstrated
positive pre-clinical proof-of-concept in various in-vitro and in-vivo models. |
|
● |
In-depth
profiling of a limited set of candidates for potential use in clinical development. |
|
● |
Confirmed
AIM Biologicals’ mechanism of action and efficacy in ex-vivo studies in human blood samples from both NMOSD and PD patients. |
Next
Steps
|
● |
Evaluation
of manufacturing strategy and initiation of production of selected development candidates. |
|
● |
Ongoing
compilation of a comprehensive pre-clinical data package for scientific advice meetings with regulatory authorities, expected to
take place in the near future. |
Delayed
Clearance Parathyroid Hormone (“DC-PTH”, AEZS-150) Fusion Proteins: Potential treatment for chronic hypoparathyroidism
AEZS-150
is a fusion protein of PTH [1-34] coupled to a modified human growth-hormone binding protein (GHBP). Preclinical results so far indicate
the potential for maintaining regular calcium and phosphate levels in blood longer and more consistently than with current treatments.
This project aims to address this debilitating orphan disease, which is currently without satisfactory treatment options, with weekly
instead of daily injections.
“There
is a major unmet need for physiological parathyroid hormone replacement in patients with hypoparathyroidism, either congenital or acquired
from neck surgery, who have an impaired quality of life and increased morbidity and mortality on current therapy. DC-PTH will address
this unmet need,” commented Prof. Richard Ross, MD, FRCP, Department of Oncology and Metabolism at Sheffield University (UK). “Aeterna
has made great progress in the manufacturing process development of AEZS-150 and repeating validation studies in models of hypoparathyroidism
required before undertaking trials in patients.”
Recent
Highlights
|
● |
Detailed
profiling of AEZS-150 through in-vitro studies and in-vivo models of hypoparathyroidism. |
|
● |
Established
a master cell bank for a cell line expressing AEZS-150 in good yield. |
|
● |
Continued
progress in the development of a production process suitable for larger scale GMP manufacturing. |
Next
Steps
|
● |
Meet
with regulatory authorities to determine the development path forward; Company expects such a meeting in Q4/2023, and as outcome,
an abbreviated safety and toxicology program as the active principle ([1-34]-PTH fragment) is already approved and in use. |
|
● |
Initiate
IND-enabling preclinical studies in 2024. |
Macimorelin
Therapeutic (AEZS-130): Ghrelin agonist in development for the treatment of ALS (Lou Gehrig’s disease)
Amyotrophic
Lateral Sclerosis (ALS) is a debilitating and deadly orphan disease, and those who suffer from this terminal condition have few treatment
options. Macimorelin’s (AEZS-130) multiple modes of action should have the potential to improve the quality of life for these patients.
Recent
Highlights
|
● |
Successful
development of an alternative formulation suitable for use in ALS. |
|
● |
Accumulating
data for positive effects of AEZS-130 treatment on survival of motor-neurons. |
|
● |
Continued
assessment of AEZS-130 in transgenic mouse ALS models and in human patient-derived neuron cultures. |
|
● |
Completion
of initial toxicology and safety studies to support clinical development as a therapeutic, in addition to the already existing body
of safety and toxicology data from our macimorelin diagnostic development. |
Next
Steps
|
● |
Following
achievement of proof-of-concept, the Company will seek to have a scientific advice meeting with regulatory authorities to discuss
program development next steps. |
|
● |
Completion
of toxicology and safety studies to support treatment over prolonged periods. |
Diagnostics
Development and Commercialization Update
Macimorelin
Diagnostic: Approved and commercialized as test for adult growth hormone deficiency and in clinical Phase 3 development for childhood-onset
growth hormone deficiency (“CGHD”) testing.
Aeterna
is currently conducting its pivotal Phase 3 safety and efficacy study AEZS-130-P02 (the “DETECT-trial”) evaluating macimorelin
for the diagnosis of Childhood Onset Growth Hormone Deficiency (“CGHD”). Most clinical sites in the U.S. as well as European
countries are open for patient recruitment.
Recent
Highlights
|
● |
Phase
3 Study: Significant progress made with DETECT patient recruitment also by engagement of an additional Clinical Research Organization
(CRO). Currently three new countries (Armenia, Slovakia, and Turkey), have ongoing DETECT clinical trial application activities and
almost half the foreseen subjects have meanwhile concluded the trial. |
|
● |
Macimorelin
Commercialization: Having regained full rights to Macrilen® for the U.S. and Canada from Novo Nordisk in May 2023,
the Company is actively focused on identifying an alternate development and commercialization partner for Macrilen®
for U.S. and Canada. |
“We
continue to manage our cash responsibly with a balanced de-risked development approach, which we believe enables us to optimize the Company’s
capital and human resources,” added Giuliano La Fratta, Chief Financial Officer of Aeterna. “We remain focused on advancing
our programs to their next phase of development, guided by the data and financial risk/reward as we do so. Based on our current projections,
we believe the Company has the ability to meet its currently anticipated cash needs into 2025.”
