Regulatory News:

Advicenne (Euronext Growth Paris ALDVI - FR0013296746), a specialty pharmaceutical company dedicated to the development and commercialization of innovative treatments for those suffering from rare renal diseases, today announced that gross sales1 for the first half of 2024 totaled 2.4 million euros, up 8.8% over the same period last year. Gross sales do not include royalties receivable from partners for the first half.

In line with the Company's strategic plan, sales growth was sustainably driven mainly by Sibnayal® sales. The latter posted gross sales of 1.1 million euros, up 12.9% for the first six months of the year compared with the first half of 2023. In France, performance was solid, reflecting the strengthening of the sales and marketing team. In other European countries, Sibnayal® recorded several successes, but continued to be penalized by difficulties in gaining access to reimbursement. In addition, inventory effects in the first half of 2023 significantly limited growth in H1 2024. Likozam® and Levidcen® recorded sales of 1.0 and 0.3 million euros respectively.

In the latest discussions between Advicenne and Primex International AG during this period, it became apparent that Primex is not in a position to honor all the commitments made in the contract signed in 2016 concerning the payment of royalties in 2025. In order to protect its interests, Advicenne is continuing discussions with Primex and hopes to reach a final agreement by the end of the year.

Finally, following the granting of orphan drug status for ADV7103 in cystinuria in April 2024 and an initial round of exchanges with the FDA on the basis of European clinical data in distal renal tubular acidosis, Advicenne is continuing its work over the summer to clarify the regulatory pathway for ADV7103 in the US in these indications. To this end, Advicenne enjoys the support of several key opinion leaders, both American and European, as well as patient associations.

At the date of this press release, the Company's cash flow horizon is Q1 2025.
