Posters to be presented highlighting research investigating pegtibatinase as the first potential disease-modifying treatment for classical homocystinuria

SAN DIEGO, April  04, 2024  (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc., (Nasdaq: TVTX) today announced that the Company will present eight posters in classical homocystinuria (HCU) at Society for Inherited Metabolic Disorders (SIMD) in Charlotte, North Carolina from April 14-17, 2024, and Genetic Metabolic Dieticians International (GMDI) in Charlotte, North Carolina from April 17-20, 2024.

At SIMD and GMDI, the Company will present the trial design of the pivotal Phase 3 HARMONY Study of pegtibatinase, a novel investigational enzyme replacement therapy for the treatment of classical HCU. Additionally, the Company will share insights on the development of an innovative tool used for dietary management and monitoring in the Phase 3 HARMONY Study and open-label extension ENSEMBLE Study, and the positive results from cohort 6 in the placebo-controlled Phase 1/2 COMPOSE Study of pegtibatinase in classical HCU.

"Classical HCU is an isolating and devastating rare disorder with very limited treatment options, including adherence to highly restrictive diets, leaving patients and their caregivers with immense challenges," said Jula Inrig, M.D., chief medical officer of Travere Therapeutics. "We look forward to participating at both of these prestigious metabolic medical meetings, and we are excited about our work pioneering the first potential disease-modifying treatment for the thousands of people affected by classical HCU."

About Classical Homocystinuria

Classical homocystinuria (HCU) is a rare genetic metabolic disorder caused by a deficiency in the enzyme cystathionine beta synthase (CBS). CBS is a pivotal enzyme that is essential for the management of methionine and cysteine in the body. Classical HCU leads to toxic levels of homocysteine that can result in life-threatening thrombotic events such as stroke, pulmonary embolism and deep vein thrombosis, ophthalmologic and skeletal complications, as well as developmental delay. Current treatment options are limited to protein-restricted diet and use of vitamin B6 and betaine.

About Pegtibatinase

Pegtibatinase is an investigational PEGylated, recombinant enzyme replacement therapy designed to address the underlying cause of classical homocystinuria (HCU). In preclinical studies, pegtibatinase has demonstrated an ability to reduce total homocysteine levels and improve clinical parameters. Pegtibatinase is currently advancing in the ongoing Phase 1/2 COMPOSE Study to assess its safety, tolerability, pharmacokinetics, pharmacodynamics and clinical effects in patients with classical HCU. In May 2023, the Company announced that data from four patients treated with the highest dose of pegtibatinase showed a clinically meaningful 67.1% mean relative reduction in total homocysteine from baseline and was generally well-tolerated after 12 weeks of treatment. To date, the pegtibatinase program has been granted Breakthrough Therapy designation, Rare Pediatric Disease and Fast Track designations by the FDA, as well as Orphan Drug designation in the U.S. and Europe.
