Versantis’ lead product candidate VS-01 has been has granted orphan drug designation (ODD) by the Food and Drug Administration (FDA) for the treatment of hyperammonemia (HA) in inborn errors of metabolism (IEM).
“This orphan drug designation from the FDA validates the scientific rationale of VS-01 in a new indication encompassing multiple genetic disorders where there is a vital need to remove the life-threatening build-up of ammonia,” said Meriam Kabbaj, Chief Operations Officer and Co-founder of Versantis. “VS-01 has now received US FDA ODD for two main indications, hyperammonemia in inborn errors of metabolism and Acute-on-chronic Liver Failure (ACLF). Orphan drug incentives considerably strengthen the clinical development plan of our liposomal scavenging platform technology and provide a huge opportunity to soon address the growing burden of metabolic / liver diseases.”
The US FDA ODD program is designed to provide incentives to sponsors developing drugs and biologics for rare diseases and conditions, in part defined as affecting fewer than 200,000 people in the United States. Sponsors of designated orphan drugs are eligible for tax credits for clinical trial costs, waiver of the user fee for marketing applications and, upon approval, consideration for seven years of marketing exclusivity.
“VS-01 is potentially a game-changing medication for the treatment of acute hyperammonemia in an emergency setting. The new designation from the FDA continues to validate our approach and development of VS-01, which was shown to be safe and well tolerated in our Phase 1b clinical study in patients with decompensated liver cirrhosis,” said Vincent Forster, Versantis’ Co-founder and CEO. “Building on this encouraging first experience in patients, we are in the process of raising new funds to continue advancing VS-01 towards its much-needed use in clinical practice.”
