Advicenne’s Lead Candidate Approved for Orphan Drug Designation in the Treatment of Cystinuria in Europe

Regulatory News:

Advicenne (Paris:ADVIC) (BSE:ADVIC) (Euronext : ADVIC - FR0013296746), a specialty pharmaceutical company focused on the development and commercialization of therapeutic products for rare kidney disease, today announced that its lead drug candidate, ADV7103, has been granted orphan drug designation by the European Medicines Agency (EMA) for the treatment of cystinuria in Europe.

“The EMA’s positive opinion regarding orphan drug designation for ADV7103 is of significant strategic importance to the development of this product,” comments Dr. Luc-André Granier, Co-Founder and CEO of Advicenne. “This designation entails important advantages relating to the clinical development of ADV7103, as well as direct access to the centralized procedure for marketing authorization and 10-year marketing exclusivity following authorization.”

Orphan drug designation is granted to medicines in development for the treatment, prevention and diagnosis of serious or debilitating illnesses whose prevalence does not exceed 5 out of 10,000 people in the European Union and for which there exists no satisfactory solutions or alternative treatments.

Cystinuria is a genetic disease characterized by a buildup of the amino acid cystine in the kidneys and bladder, leading to the formation of cystine stones. These cystine stones generate various complications, such as hypertension, intense abdominal pain, recurrent urinary tract infections, renal function impairment . These complications can ultimately lead to kidney failure.

The prevalence of cystinuria in Europe is estimated at 1 out 10,000, or around 70,000 patients affected. A pivotal Phase II/III CORAL study is currently underway in order to evaluate the efficacy, safety, tolerance and compliance of ADV7103 in patients suffering from cystinuria in Europe.

In 2017, ADV7103 was granted orphan drug designation in the treatment of distal renal tubular acidosis (dRTA), a rare kidney disorder that occurs when the kidneys are unable to effectively remove the buildup of circulating acids in the blood. ADV7103 has already demonstrated its efficacy and safety in the treatment of dRTA through Phase III clinical trials in Europe and is currently in Phase III trials for this indication in the United States and Canada.

What is Orphan Drug Designation?

Orphan drug designation is a status intended to encourage the development of medicines for the treatment of rare diseases. It offers a range of strategic incentives including European marketing exclusivity following marketing authorization in the EU. In addition, orphan drug designation can include subsidies and tax credits, clinical protocol assistance and reductions in regulatory fees during development, and even registration of the product.

About Advicenne

Advicenne (Euronext ADVIC) is dedicated to developing and commercializing innovative treatments for those suffering from rare kidney disease. Our lead drug candidate is currently in late-stage clinical trials for two indications.

In 2017, ADV7103 was granted orphan drug designation by the European Commission in the treatment of distal renal tubular acidosis (dRTA), a rare kidney disorder that occurs when the kidneys are unable to effectively remove the buildup of circulating acids in the blood. ADV7103 is currently in Phase III clinical trials for this indication in Europe, the United States and Canada, and a marketing application for the drug candidate has been submitted for centralized European review.

While we prepare the European commercial launch for dRTA, we are simultaneously conducting trials for ADV7103 in the treatment of cystinuria, a genetic disease characterized by a buildup of the amino acid cystine in the kidneys and bladder. ADV7103’s Phase II/III European clinical trials for this second indication were recently expanded to Belgium.

At Advicenne, we are committed to innovating in the areas of formulation and dosage. Tasteless and easy to administer, our products are commercialized in small-size formats that offer flexible, personalized dosing – because path-breaking treatments for rare diseases should be available to patients of all ages.

Headquartered in Nîmes, France, Advicenne has been listed on the Euronext Paris stock exchange since 2017 and was cross-listed on the Euronext Brussels stock exchange in 2019.
