PRESS RELEASE

SAN DIEGO, Aug. 24, 2023 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc. (NASDAQ: TVTX) today announced that the Company will present clinical data from the Phase 1/2 COMPOSE Study of pegtibatinase, a novel investigational enzyme replacement therapy being evaluated for the treatment of classical homocystinuria (HCU), at the Society for the Study of Inborn Errors of Metabolism (SSIEM) Annual Symposium in Jerusalem, Israel, August 29 – September 1, 2023.

The Company and its collaborators will also present analyses on its prospective HCU natural history study, the prevalence of HCU, and the burden of HCU from the patient perspective highlighting the devastating nature of this rare metabolic disease over patients’ lifetimes and underscoring the urgent need for new treatments. In addition, the Company will present data on the clinical burden of HCU and the relationship between total homocysteine (tHcy) and clinical outcomes, which has been recognized as one of the highest ranked posters at SSIEM.

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 supplemental 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. 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 US and Europe.
