DEER PARK, Ill., Dec. 20, 2021 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc ETON, an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases and ANI Pharmaceuticals, Inc ANIP, a bio-pharmaceutical company serving patients in need through the development and manufacturing of high-quality generic and branded medicines, today announced the commercial launch of Carglumic Acid tablets.

The product will be marketed by Eton Pharmaceuticals and is the first and only FDA-approved generic version of Carbaglu®.

The product application is owned by Novitium Pharmaceuticals, a subsidiary of ANI Pharmaceuticals.

"We are excited to offer patients a convenient Carglumic Acid product that does not require refrigeration and to provide it at a lower price than the existing Carbaglu®. We believe the adoption of our product will result in significant financial savings to the U.S. healthcare system and to many patients through lower co-pay and co-insurance costs," said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

The product application was granted Competitive Generic Therapy (CGT) designation by the FDA, and as a result, the product is expected to receive 180 days of generic exclusivity. "This approval further strengthens ANI's focus on niche opportunities and maintains our leadership position in Competitive Generic Therapy approvals," said Nikhil Lalwani, CEO Of ANI Pharmaceuticals.
