Preclinical and Clinical Programs Update:

Diagnostics Development Pipeline

Macimorelin Diagnostic: Ghrelin agonist in development for diagnostic use in childhood-onset growth hormone deficiency (“CGHD”)

Aeterna Zentaris is currently conducting its pivotal Phase 3 safety and efficacy study AEZS-130-P02 ("the DETECT-trial") evaluating macimorelin for the diagnosis of CGHD. Children and adolescents from two to less than 18 years of age with suspected GHD are to be included. The study is expected to include approximately 100 subjects worldwide, with at least 40 subjects in pre-pubertal and 40 subjects in pubertal status. Macimorelin growth hormone stimulation test (“GHST”) will be performed twice for repeatability data and two standard GHSTs will be used as controls: arginine (i.v.) and clonidine (p.o.). On April 22, 2021, the U.S. FDA Investigational New Drug Application associated with this clinical trial became active. The first clinical site in the U.S. is now open for patient recruitment.

Next Steps

  • Conduct and completion of the DETECT-trial.

Therapeutics and Vaccine Development Pipeline

AIM Biologicals: Targeted, highly specific autoimmunity modifying therapeutics for the potential treatment of neuromyelitis optica spectrum disorder (“NMOSD”)

In January 2021, Aeterna Zentaris entered into an exclusive patent license and research agreement with Julius-Maximilians-University of Wuerzburg, Germany for worldwide rights to develop, manufacture and commercialize AIM Biologicals for the potential treatment of NMOSD. The Company is currently conducting in-vitro and in-vivo assessments to identify and characterize an AIM Biologicals-based development candidate for the treatment of NMOSD and to develop a manufacturing process for the selected candidate. Additionally, the Company recently engaged neuro-immunologist, Dr. Michael Levy, who will provide scientific support and advice in the field of inflammatory CNS disorders, autoimmune diseases of the nervous system, and NMOSD.

Next Steps

  • Conduct further preclinical research to identify and characterize an AIM Biologicals-based development candidate for the treatment of NMOSD.
  • Manufacturing process development for selected candidate.

Macimorelin Therapeutic: Ghrelin agonist in development for the treatment of ALS (Lou Gehrig’s disease)

In January 2021, the Company entered into a material transfer agreement (“MTA”) with Queensland University, Australia, to provide macimorelin for the conduct of preclinical and subsequent clinical studies evaluating macimorelin as a potential therapeutic for the treatment of ALS (Lou Gehrig’s disease). Queensland University researchers have filed for supportive grants and aim to conduct preclinical studies in multiple models to demonstrate the therapeutic reach of macimorelin on disease progression and disease-specific pathology. They also plan to conduct a subsequent investigator initiated clinical trial given positive pre-clinical results.

Macimorelin, a ghrelin agonist, is an orally active small molecule that stimulates the secretion of growth hormone from the pituitary gland. Acting via this mechanism, it is believed that macimorelin may slow the progression of certain neurodegenerative diseases like ALS.

Next Steps

  • Work with Queensland University to conduct proof-of-concept studies with macimorelin in disease-specific animal models.
  • Assess alternative formulations.
  • Formalize preclinical development plan.

Delayed Clearance Parathyroid Hormone (DC-PTH) Fusion Polypeptides: Potential treatment for primary hypoparathyroidism

In March 2021, Aeterna entered into an exclusive patent and know-how license agreement and research agreement with The University of Sheffield, United Kingdom, for the intellectual property relating to DC-PTH fusion polypeptides with delayed clearance covering the field of all human uses. In consultation with the University, Aeterna has selected AEZS-150 as the lead candidate in its delayed clearance parathyroid hormone fusion polypeptides (“DC-PTH”) program. Aeterna will now start the formal preclinical development of AEZS-150 in preparation for a potential IND filing for conducting the first in-human clinical study of AEZS-150. AEZS-150 is being developed with the goal of providing a potential new treatment option of primary hypoparathyroidism in adults.

Next Steps

  • Work with The University of Sheffield to conduct in depth characterization of development candidate (in-vitro and in-vivo).
  • Develop manufacturing process.

Oral Coronavirus Vaccine Platform: Potential orally active COVID-19 (SARS-CoV-2) live-attenuated bacterial vaccine

In February 2021, Aeterna entered into an exclusive option agreement with Julius-Maximilians-University to evaluate a preclinical, potential COVID-19 vaccine developed at Julius-Maximilians-University. In March 2021, the Company exercised its option and entered into a license agreement where the Company was granted an exclusive, world-wide, license to certain patent applications and know-how owned by Julius-Maximilians-University to research and develop, manufacture, and sell a potential COVID-19 vaccine.

Julius-Maximilians-University also granted Aeterna an option for the exclusive use of certain patent applications and know-how in an additional, so-far undisclosed field. The Company has six months from the date of the license agreement to exercise that option. Additionally, Aeterna entered into a Research Agreement under which the Company has engaged Julius-Maximilians-University on a fee-for-service basis to conduct supplementary research work and preclinical development studies on the potential vaccine, the results of which will be included within the scope of the license agreement.

Next Steps

  • Conclude in-vivo immunology experiments with antigen variant vaccine candidates.
  • Perform challenge experiments in immunized transgenic animals as proof of concept.
  • Select a development candidate for initiation of the formal preclinical toxicology and safety studies.
  • Start manufacturing process assessment / development.

Financing and Warrant Exercises

During the period between January 1, 2021 and June 30, 2021, holders have exercised certain of the Company’s outstanding warrants to purchase 35,011,187 of the Company’s common shares for gross proceeds of approximately $20.0 million. The Company had $69.9 million cash and cash equivalents at June 30, 2021 (March 31, 2021 – 73.4 million).

Summary of Second Quarter 2021 Financial Results

Results of operations for the three-month period ended June 30, 2021

For the three-month period ended June 30, 2021, we reported a consolidated net loss of $2.0 million, or $0.02 loss per common share (basic), as compared with a consolidated net loss of $3.5 million, or $0.15 loss per common share (basic) for the three-month period ended June 30, 2020. The $1.5 million improvement in net loss is primarily from an increase in net finance income of $2.1 million and an increase of $0.5 million in total revenues, partially offset by an increase of $1.2 million in total operating expenses.

Revenues

  • Our total revenue for the three-month period ended June 30, 2021 was $0.60 million as compared with $0.07 million for the same period in 2020, representing an increase of $0.53 million. The 2021 revenue was comprised of $0.5 million in licensing revenue (2020 - $0.02 million), $0.04 million in supply chain revenue (2020 - $0.04 million) and $0.02 million in royalty income (2020 - $0.01 million). The licensing revenue was earned from the recognition of a portion of the deferred €5 million payment from Novo Nordisk received with the amendment to the Novo License agreement in the fourth quarter of 2020.

Operating expenses

  • Our total operating expenses for the three-month period ended June 30, 2021 was $2.7 million as compared with $1.5 million for the same period in 2020, representing an increase of $1.2 million. This increase arose primarily from a $0.5 million increase in research and development costs and $0.5 million increase in general and administrative expenses and an increase of $0.1 million in selling expenses. This increase in total operating expense is due to the initiation of research and development projects as announced in the first quarter of 2021, and higher public company costs incurred holding our annual shareholders meeting in May 2021, subsequent to our issuance of common shares in the February 2021 financing and the 2021 warrant exercises, in addition to higher auditor fees mostly related to F-3 warrant registration filings.

Net finance (costs) income

  • Our net finance income for the three-month period ended June 30, 2021 was $0.1 million as compared with net finance costs of ($2.0 million) for the same period in 2020, representing an increase in net finance income of $2.1 million. This is primarily due to the $2.1 million decrease in change in fair value of warrants. Unlike as at June 30, 2020, the Company did not account for its warrants as liabilities as at June 30, 2021. As at June 30, 2020, the fair value of such liabilities was classified as a finance cost in the consolidated statements of loss and comprehensive loss.
