Finalization of exclusive discussions with a leading investor to monetize royalties from sales of TWYMEEG® (Imeglimin) in Japan and cash runway

With the priority objective of relaunching its R&D activities and executing its strategic plan in rare diseases, the Company has focused in recent months on securing additional financing, in particular non-dilutive solutions. In this context, the Company is currently finalizing exclusive negotiations initiated several months ago with a leading investor to monetize royalties from TWYMEEG® (Imeglimin) sales in Japan. In addition, the Company is in advanced discussions – in some cases on an exclusive basis – with several potential partners for each of its three products: Imeglimin, for several countries not covered by its agreement with Sumitomo Pharma, PXL065 and PXL770.

Based on:

• (i) its cash position on June 30, 2024,
• (ii) tranches already drawn6 or fully available as of the date of this press release under the equity-linked financing facility with IRIS,
• (iii) no research and development expenses, and
• (iv) a strict control of operating expenses,

Poxel expects that its resources, including funds available to it, will be sufficient to maintain its operations and capital expenditure until completion of the current process underway to monetize royalties from sales of TWYMEEG® (Imeglimin) in Japan.

Once its social and consolidated financial statements are approved by the Board of Directors, Poxel will inform the market and its shareholders, and will publish its Universal Registration Document, including its 2023 annual financial report and its new financial calendar for 2024, including the new date set of its General Meeting.
