Forward-looking statements are frequently, but not always, identified by words such as "expects," "anticipates," "believes," "intends," "potential," "possible," and similar expressions. Such statements, based as they are on current expectations of management, inherently involve numerous risks, uncertainties and assumptions, known and unknown, many of which are beyond our control. Forward-looking statements in this press release include, but are not limited to, those relating to: Aeterna's expectation with respect to Study P02 (including the ability to commence in the second quarter of 2021, to enroll subjects in the USA or elsewhere in Study P02, and expectations that Study P02 are suitable to support a claim (regulatory approval) for potential stand-alone testing with macimorelin); Aeterna's expectation that, upon receipt of pricing and reimbursement approvals, macimorelin will be marketed in Europe and the United Kingdom; the aims and details of the pre-clinical and potential clinical studies involving the potential use of macimorelin to treat an undisclosed neurodegenerative disease being conducted by Queensland University; the potential of the coronavirus vaccine platform technology licensed from Julius-Maximilians-University (and any vaccine candidates using that technology) to be effective as a vaccine against COVID-19 (SARS-CoV-2) or any other coronavirus disease or to offer an alternative to other approved vaccines against COVID-19; the ability to obtain approval to commence any clinical trial or the timeline to develop any potential vaccine and the characteristics of any potential vaccine; plans regarding the DC-PTH fusion polypeptides licensed from the University of Sheffield, plans regarding AIM Biologicals in-licensed from Julius-Maximilians-University and the potential to treat NMOSD; and Aeterna's intentions with respect to growth opportunities and its business focus, including with respect to its cash position and development pipeline (including the ability to accelerate its development pipeline).

Forward-looking statements involve known and unknown risks and uncertainties, and other factors which may cause the actual results, performance or achievements stated herein to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such risks and uncertainties include, among others, our reliance on the success of the pediatric clinical trial in the European Union and U.S. for Macrilen™ (macimorelin); the commencement of Study P02 may be delayed or we may not obtain regulatory approval to initiate that study, we may be unable to enroll the expected number of subjects in Study P02 and the result of Study P02 may not support receipt of regulatory approval in CGHD, we may be delayed or unsuccessful in obtaining pricing and reimbursement approvals in Europe and the UK to market macimorelin; the coronavirus vaccine platform technology (and any vaccine candidates using that technology) licensed from Julius-Maximilians-University has never been tested in humans and so further pre-clinical or clinical studies of that technology and any vaccine developed using that technology may not be effective as a vaccine against COVID-19 (SARS-CoV-2) or any other coronavirus disease; that the timeline to develop a vaccine may be longer than expected; that such technology or vaccines may not be capable of being used orally, may not have the same characteristics as vaccines previously approved using the Salmonella Typhi Ty21a carrier strain; results from ongoing or planned pre-clinical studies of macimorelin by Queensland University or for our other products under development may not be successful or may not support advancing the product to human clinical trials; our ability to raise capital and obtain financing to continue our currently planned operations; our now heavy dependence on the success of Macrilen™ (macimorelin) and related out-licensing arrangements and the continued availability of funds and resources to successfully commercialize the product, including our heavy reliance on the success of the License Agreement with Novo Nordisk; the global instability due to the global pandemic of COVID-19, and its unknown potential effect on our planned operations; our ability to enter into out-licensing, development, manufacturing, marketing and distribution agreements with other pharmaceutical companies and keep such agreements in effect. Investors should consult our quarterly and annual filings with the Canadian and U.S. securities commissions for additional information on risks and uncertainties, including those risks discussed in our Annual Report on Form 40-F and annual information form, under the caption "Risk Factors".
