Advicenne Announces Submission of European Marketing Authorization Application (MAA) for ADV7103 as Treatment for Distal Renal Tubular Acidosis (dRTA)

Regulatory News:

Advicenne (Paris:ADVIC) (Euronext: ADVIC – FR0013296746), specializing in the development of adult and pediatric therapeutic products for the treatment of orphan renal and neurological diseases, announces today that it has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for its lead drug candidate, ADV7103, as a treatment for distal renal tubular acidosis (dRTA).

The application comes after positive results in a pivotal Phase III clinical trial (B21CS) and its twenty-four-month extension study (B22CS). In view of patient numbers and the absence of approved treatments for dRTA, ADV7103 had previously received orphan medicinal product designation in Europe in 2017.

Marketing authorization for ADV7103 is anticipated in mid-2020. This schedule is in keeping with the late-2020 commercial launch strategy announced by Advicenne at its IPO: directly in the five principal European markets (France, Germany, Italy, Spain, United Kingdom) and through partnerships in other European Union countries.

With Ozalin® (ADV6209), which received authorization in September of 2018, approval for ADV7103 would make Advicenne one of the very rare French biotechnology companies to obtain two marketing authorizations for innovative products developed in-house.

"This European marketing authorization application represents a major step in Advicenne’s growth,” observes Caroline Roussel, Advicenne Co-Founder and Director of Operations, "one made possible by the outstanding work of our teams.”

"This application fulfills the milestones announced at Advicenne’s initial public offering. In addition to its first obtained MAA, this application promotes the company to a quite advanced development stage” concludes Dr. Luc-André Granier, Chief Executive Officer of Advicenne, "We are delighted to be actively preparing the commercial launch of ADV7103.”

About Distal Renal Tubular Acidosis (dRTA)

dRTA is an orphan disease characterized by a failure in the renal excretion of the acids generated through metabolism. The excess of acids thus accumulated in the blood leads to an imbalance in pH (acidosis) as well as multiple other complications. These include growth retardation and rickets (a disease affecting bone development) in children, and a series of metabolic disorders such as low potassium levels (hypokalemia), high calcium levels (hypercalcemia), elevated calcium in the urine (hypercalciuria) resulting in kidney stones, the formation of calcium deposits in the kidneys (calcinosis) as well as possible kidney failure.

Whether genetic, or acquired as a consequence of an autoimmune disease, dRTA affects an estimated 30,000 patients in Europe and approximately 20,000 in the United States.
