SEOUL, South Korea, May 25, 2021 /PRNewswire/ — Mezzion Pharma Co., Ltd. (140410.KQ) is pleased to announce today that it has received notice from the FDA that its NDA submitted on March 26, 2021 for the use of udenafil to treat SVHD patients who have undergone Fontan palliation is sufficiently complete to permit a substantive review (the «FDA Notice»).

In the FDA Notice, the FDA advised that there were no filing review issues identified.  Thus, the FDA review cycle has started with an expected NDA approval date of March 26, 2022. The FDA also advised in the FDA Notice that the FDA is not currently planning to hold an advisory committee meeting to discuss Mezzion’s NDA.

The FDA had previously granted Mezzion’s request to designate udenafil for treatment of single ventricle congenital heart disease as a drug for a Rare Pediatric Disease.

To encourage the development of drugs to treat rare pediatric diseases, the US established a priority review voucher (PRV) program under which the FDA awards a PRV to a drug sponsor (manufacturer) upon approval of that sponsor’s drug for the treatment of a rare pediatric disease.

Mezzion fully expects that, upon FDA approval of its NDA for the treatment of SVHD patients, a rare pediatric disease, it will be awarded a PRV, at which time the PRV will be fully redeemable and/or transferrable.

Mezzion looks forward to the FDA review process and to bringing a novel pharmacotherapeutic option to this rare pediatric disease population.  

About the Fontan Procedure and Subsequent Expectations

The Fontan procedure is a surgical intervention that allows for the survival of children born with congenital heart disease characterized by only a single functional pumping chamber. This procedure consists of re-configuring the circulation to allow the single ventricle to pump blood to the body while connecting the great veins directly to the arteries that bring blood to the lungs. In this «Fontan circulation» the blood returning from the body bypasses the heart and travels to the lungs without the assistance of a dedicated right ventricle pumping chamber. The goal of the Fontan procedure is to separate the systemic and pulmonary circulations and to improve oxygen levels by redirecting venous blood directly to the lungs.

While the Fontan procedure creates a stable circulation, the risk of hospitalization and cardiac death rises significantly in the second and third decades after Fontan completion, a risk that is associated with a decline in exercise capacity. The Fontan circulation is also associated with non-cardiac complications such as protein-losing enteropathy, plastic bronchitis, and liver failure, all of which can be attributed to a chronic elevation in central venous pressure and a chronically reduced cardiac output. For all of these reasons, a 35 year-old patient who has gone through Fontan palliation has the approximate life expectancy of a 75 year old with normal cardiac physiology.
