Travere Therapeutics, Inc. announced the Company has opened enrollment in the HARMONY Study, a global, randomized pivotal Phase 3 clinical trial of pegtibatinase, a novel investigational enzyme replacement therapy being evaluated for the treatment of classical homocystinuria (HCU). Classical HCU is a rare genetic metabolic disorder caused by a deficiency in the enzyme cystathionine beta synthase (CBS). The study is designed to determine the safety and efficacy of pegtibatinase in reducing plasma total homocysteine (tHcy) levels, a key treatment goal in classical HCU, compared to placebo in participants who are receiving standard of care.

Rare Revolution Magazine: Striving for better
Homocystinuria (HCU) has been on the Recommended Uniform Screening Panel (RUSP) in the US for nearly 15 years, yet babies with the condition are still being missed at birth, risking serious health consequences. Danae' Bartke is the executive director of HCU Network America and has classical homocystinuria (HCU). She explains that while improvements in newborn screening processes can potentially help more babies to receive that vital early diagnosis, progress relies on each state updating their screening protocols: something her organization is working tirelessly towards.

To qualify, available clinical and non-clinical data need to demonstrate meaningful therapeutic potential. The benefits of Fast Track designation include opportunities for frequent meetings with the FDA to discuss trial design, development plans and data needed to support drug approval, as well as the ability to submit a registrational filing for approval on a rolling basis, and eligibility for priority review, if relevant criteria are met. SYNB1353, an orally-administered, non-systemically absorbed drug candidate designed to consume methionine in order to lower homocysteine levels, is currently being evaluated in a Phase 1 study in healthy volunteers.

Inside Colorado's Battle Against Rare Diseases
One in 10 Centennial Staters has a so-called orphan disease—the local medical community is trying to help them.
In 2011, doctors told Brittany Parke that her newborn baby boy was completely healthy, but she wasn’t so sure. The 25-year-old was living in upstate New York, and as a second-time mom, she knew something wasn’t quite right with little Drew. The two-month-old was sleeping excessively and refused to eat. Doctors brushed away her concerns. Then came the seizures. Three and a half weeks after first seeing a doctor, she began to receive answers. But by then, it was too late. Drew died shortly thereafter.

Drawing Blood to Advance New Therapies
Organizations that advocate for patients with rare diseases have a lot on their plates. Their leaders—individuals often affected by these diseases in some way—wear many hats. They become quick experts in genetics, fundraising, community building, and the needs of researchers working to better understand these disorders and develop new therapies.
When it comes to collecting biosamples for research—often one of the most important requirements of scientists—Coriell can help shoulder that burden.
