"During the first half of 2023, we achieved key milestones in the development of our main drug candidate, Sarconeos (BIO101), with a view to partnerships and market access in 2024, despite a particularly challenging financial environment.

Pursuant to an accelerated development over the last two years, we have obtained positive results from our phase 2-3 COVA. Biophytis is one of the few European companies to have obtained proof of efficacy in patients with severe forms of COVID-19. We are pursuing the pharmaceutical and regulatory development of Sarconeos (BIO101), and are currently in discussions with European and American regulatory agencies to define the conditions for market access.

In addition, thanks to the encouraging results obtained with the SARA-INT phase 2b study, Biophytis has received authorizations from the US and Belgian agencies to start the clinical SARA-31 study, which will be the first phase 3 study ever launched in sarcopenia.

Finally, the Company has strengthened its management team over the last few months, notably in pharmaceutical operations, finance and business development, in order to forge strategic partnerships for the development of Sarconeos (BIO101).With the progress made in its pipeline, Biophytis is confirming its pioneering position in the development of treatments for age-related diseases, generating a strong medical need that is set to grow very rapidly in the years ahead."

• § As in the previous year, Biophytis did not record any revenues in the first half of 2023. Operating expenses fell sharply as a result of:
  • o Lower R&D expenses related to the completion of clinical trials for the COVA and SARA programs in the second half of 2022. Residual costs relating to clinical development have been booked in 2023, but most R&D expenditure in the first half of the year concerned various preclinical studies on the Company's different programs and operations relating to the production of BIO101.
  • o A reduction in personnel costs, mainly due to the valuation of instruments giving access to capital, amounting to €322 thousand in the first half of 2023, compared with €3,533 thousand in the first half of 2022.
• § The change in net financial expense is mainly due to the valuation of financial liabilities in accordance with IFRS 9.
• § As a result of the above, the half-year loss has been significantly reduced, from €12.4 million at 30 June 2022 to €7.8 million at 30 June 2023.
• § Consolidated cash and cash equivalents at 30 June 2023 were €5.8 million. The Company received new financing during the first half, in the form of convertible bonds for €2 million and equity financing combining a private placement and a public offering for €2.3 million. Considering the registered direct offering finalized in July on Nasdaq for a gross amount of \$3.8 million, as well as the bond financing facility in place with Atlas, which may give rise to additional financing of €20 million, the Company can ensure the continuity of its operations for at least the next twelve months.

Outlook and next steps

• § COVA program
  • o H2/2023: discussions with the European Agency for the Evaluation of Medicinal Products (EMA) and the US Food and Drug Administration (FDA) in the context of scientific advice to clarify the additional information to be submitted as part of marketing authorization applications, in particular the protocol for a confirmatory phase 3 clinical study. Biophytis will also present to the agencies the possibility of extending the scope of its indication to respiratory viral diseases other than COVID-19, in particular influenza.
  • o H2/2023: request for reactivation of the authorization for the early access program in Brazil, granted in early 2022.
  • o Q1/2024: resubmission to the HAS of an application for authorization of an early access program in France.
• § SARA program

Following the authorizations received from the Belgian and US agencies to conduct a phase 3 trial, the Company will actively pursue its search for partners with a view to initiating the trial in 2024, in collaboration with global or regional pharmaceutical companies under a licensing agreement.

• § MYODA program
  • o H1/2024 : start of a phase 1-2 trial.
• § MACA program
  • o Continuing pre-clinical development work on Macuneos (BIO201) and its back-up BIO203 and preparing for clinical development in dry AMD.
