BOSTON, Dec. 17, 2020 (GLOBE NEWSWIRE) -- Albireo Pharma, Inc. (Nasdaq: ALBO), a clinical-stage rare liver disease company developing novel bile acid modulators, today announced the initiation of its global Phase 3 pivotal trial, ASSERT, Alagille Syndrome looking at Safety and Efficacy in a Randomized controlled Trial, which will evaluate odevixibat in patients with Alagille syndrome. Odevixibat is a potent, once-daily, non-systemic ileal bile acid transport inhibitor (IBATi) being investigated for the treatment of rare pediatric cholestatic liver diseases, including progressive familial intrahepatic cholestasis (PFIC), biliary atresia and Alagille syndrome (ALGS). ASSERT is Albireo’s third global trial in rare cholestatic liver conditions and furthers the Company’s efforts to deliver life-changing therapies to children and young adults living with these diseases.
ALGS is a rare multisystem genetic disorder that can affect the liver, heart and other parts of the body. Approximately 95% of patients with the condition present with chronic cholestasis, usually within the first three months of life, and as many as 88% also present with severe, intractable pruritus. Currently, there is no approved drug therapy for the treatment of ALGS.
ASSERT is a gold standard, prospective intervention trial. The double-blind, randomized, placebo-controlled trial is designed to evaluate the safety and efficacy of 120 µg/kg/day odevixibat for 24 weeks in relieving pruritus in patients with ALGS. Secondary endpoints will measure serum bile acid levels and safety and tolerability. Both the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have agreed on the study design and have indicated that a single study demonstrating safety and efficacy of odevixibat would be sufficient for regulatory filings. The trial is expected to enroll approximately 45 patients aged 0 to 17 years of age with a genetically confirmed diagnosis of ALGS across 35 sites in North America, Europe, Middle East and Asia Pacific.
“Odevixibat is the first IBAT inhibitor to have demonstrated efficacy and tolerability in a Phase 3 randomized, placebo-controlled trial, and this gives us increased confidence for positive clinical outcomes in Alagille syndrome with ASSERT,” said Ron Cooper, President and Chief Executive Officer of Albireo. “We are pleased to initiate the ASSERT study within guidance and offer hope to children and young adults around the globe with Alagille syndrome who have no approved therapeutic options today.”
Albireo recently submitted for a New Drug Application (NDA) to the U.S. FDA and a Marketing Authorization Application (MAA) to the EMA seeking approval of odevixibat for the treatment of patients with PFIC. Odevixibat has previously received Fast Track, Rare Pediatric Disease and Orphan Drug Designations in the U.S. In addition to PFIC, odevixibat has Orphan Drug Designations for the treatment of Alagille syndrome, biliary atresia and primary biliary cholangitis. The EMA has granted odevixibat accelerated assessment, Orphan Designation, as well as access to the PRIority MEdicines (PRIME) scheme for the treatment of PFIC. The EMA’s Pediatric Committee has agreed to Albireo’s odevixibat Pediatric Investigation Plans for PFIC and biliary atresia. With U.S. and EU regulatory submissions for odevixibat in PFIC completed, the Company anticipates potential regulatory approvals, issuance of a rare pediatric disease priority review voucher and launch in the second half of 2021.
Odevixibat is also currently being evaluated in the ongoing PEDFIC 2 Phase 3 open-label trial in patients with PFIC, and the BOLD Phase 3 trial in patients with biliary atresia. The Company provides an Expanded Access Program for eligible patients with PFIC in the U.S., Canada, Australia and Europe.
About Alagille Syndrome
Alagille syndrome (ALGS) is a rare, multisystem genetic disorder that can affect the liver, heart, skeleton, eyes, central nervous system, kidneys and facial features. Liver damage is caused by a paucity of bile ducts preventing bile flow from the liver to the small intestine. Approximately 95% of patients with ALGS present with chronic cholestasis, usually within the first three months of life, and up to 88% also present with severe, intractable pruritus. Currently, there are no approved drug treatments.
About PFIC
Progressive familial intrahepatic cholestasis (PFIC) is a rare disorder that causes progressive, life-threatening liver disease. Patients have impaired bile flow, or cholestasis, caused by genetic mutations. The resulting bile build-up in liver cells causes liver disease and symptoms. The most prominent and problematic ongoing manifestation of the disease is pruritus, or intense itching, which often results in a severely diminished quality of life. Other symptoms include jaundice, poor weight gain and slowed growth. In many cases, PFIC leads to cirrhosis and liver failure within the first 10 years of life, and nearly all people with PFIC require treatment before age 30. There are no drugs currently approved for PFIC, only surgical options that include partial external biliary diversion (PEBD) and liver transplantation. Additional information on PFIC is available at https://www.pficvoices.com.
About Biliary Atresia
Biliary atresia is a rare pediatric liver disease with symptoms typically developing about two to eight weeks after birth. Damaged or absent bile ducts outside the liver result in bile and bile acids being trapped inside the liver, quickly resulting in cirrhosis and even liver failure. Children have clay-colored or no color in their stools and jaundice, among other things, and a few patients are pruritic. Biliary atresia is the most common pediatric cholestatic liver disease and is the leading cause of liver transplants among children as there are no approved drug treatments.
About Odevixibat
Odevixibat is an investigational product candidate being developed to treat rare pediatric cholestatic liver diseases, including progressive familial intrahepatic cholestasis (PFIC), biliary atresia and Alagille syndrome. A potent, once-daily, non-systemic ileal bile acid transport inhibitor (IBATi), odevixibat acts locally in the small intestine. Odevixibat does not require refrigeration and can be taken as a capsule for older children, or opened and sprinkled onto food, which are factors of key importance for adherence in a pediatric patient population. Odevixibat is currently being evaluated in the ongoing PEDFIC 2 open-label trial the BOLD Phase 3 trial in patients with biliary atresia, and the global Phase 3 ASSERT trial for ALGS.
