SAN DIEGO, June 20, 2016 (GLOBE NEWSWIRE) -- Retrophin, Inc. (NASDAQ:RTRX) today announced the signing of a definitive agreement to purchase the rights, titles, and ownership of a liquid formulation of ursodeoxycholic acid from Asklepion Pharmaceuticals, LLC. Retrophin intends to file a New Drug Application with the U.S. Food and Drug Administration for the liquid formulation of ursodeoxycholic acid for the treatment of primary biliary cholangitis (PBC) in 2017.
“Liquid ursodeoxycholic acid is highly complementary to our portfolio of bile acid therapies, allowing us to leverage our current commercial infrastructure and further diversify our marketed products,” said Steve Aselage, chief executive officer of Retrophin. “By commercializing a liquid formulation of ursodeoxycholic acid, we will aim to fill a gap in care for PBC patients who have difficulty swallowing pills.”
Under the terms of the agreement, Retrophin made an upfront payment of $0.5 million and will make future payments of up to $23.5 million based on cumulative sales milestones of liquid ursodeoxycholic acid in PBC. Asklepion will be eligible to receive incremental milestone payments of up to $35.0 million in aggregate upon successful development and commercialization, including cumulative sales milestones, of liquid ursodeoxycholic acid in additional indications. Retrophin will assume all future program costs and pay Asklepion tiered royalties on future product sales.
About Ursodeoxycholic Acid
Also known as ursodiol or UDCA, ursodeoxycholic acid is a naturally occurring hydrophilic bile acid derived from cholesterol, which is indicated for the treatment of PBC and currently prescribed only in solid forms. Introducing a liquid formulation of ursodeoxycholic acid would provide healthcare professionals with a dosing alternative for patients who have difficulty swallowing tablets or capsules, and may facilitate increased compliance.
About Primary Biliary Cholangitis
Primary biliary cholangitis, also known as primary biliary cirrhosis, is a rare and chronic autoimmune disease that causes the small bile ducts in the liver to become inflamed, damaged and ultimately destroyed. This results in the buildup of bile in the liver and damage to the liver cells over time, resulting in cirrhosis, or scarring of the liver. As cirrhosis progresses, and the amount of scar tissue in the liver increases, the liver loses its ability to function.
Retrophin is a fully integrated biopharmaceutical company dedicated to delivering life-changing therapies to people living with rare diseases who have few, if any, treatment options. The Company's approach centers on its pipeline featuring clinical-stage assets targeting rare diseases with significant unmet medical needs, including sparsentan for focal segmental glomerulosclerosis (FSGS), a disorder characterized by progressive scarring of the kidney often leading to end-stage renal disease, and RE-024 for pantothenate kinase-associated neurodegeneration (PKAN), a life-threatening neurological disorder that typically begins in early childhood. Research exploring the potential of early-stage assets in several rare diseases is also underway. Retrophin's R&D efforts are supported by revenues from the Company's commercial products, Thiola®, Cholbam®, and Chenodal®.
