Trethera Announces FDA Orphan Drug Designation Granted to TRE-515 in the Treatment of Acute Disseminated Encephalomyelitis

Last Updated on August 30, 2022 by GlobeNewsWire

LOS ANGELES, Aug. 30, 2022 (GLOBE NEWSWIRE) — Trethera Corporation (“Trethera”), a biopharmaceutical company committed to developing novel drugs targeting nucleotide metabolism for the treatment of cancer and autoimmune diseases, announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Status (ODS) to TRE-515, Trethera’s first-in-class drug for the treatment of acute disseminated encephalomyelitis (ADEM). ADEM is a rare autoimmune disease where patients lose their nerve function and become paralyzed, causing death in some cases.

“The symptoms of ADEM involve a severe bout of inflammation in the central nervous system that can include the brain, spinal cord, and sometimes the optic nerves. The inflammation damages myelin, the protective substance that coats nerve fibers throughout the central nervous system. No medications have been specifically approved by the FDA to treat it,” said Dr. Peter Clark, a specialist member of the Trethera Scientific Advisory Board. “Holding ODS at this early preclinical stage is a mark of distinction and external validation. The ODS designation qualifies Trethera for certain incentives, which include FDA assistance in designing clinical trials, access to the FDA Orphan Drug Grants Program, exemption from the drug approval application fee and eligibility for seven years of marketing exclusivity.”

About Trethera

Trethera is a clinical stage privately held biopharmaceutical company dedicated to pioneering the development of novel treatments for autoimmune diseases and cancers. Founded by prominent UCLA scientists, Trethera is led by experienced management and board members. Trethera’s innovative approach to targeting nucleotide metabolism led to the development of TRE-515, an orally taken capsule twice designated by the FDA as an Orphan Drug. TRE-515 is a first-in-class clinical stage drug that inhibits deoxycytidine kinase (dCK), the rate-limiting enzyme in the nucleoside salvage pathway, one of two biosynthetic pathways that generate DNA precursors. It is believed that some forms of cancer may be preferentially dependent on the salvage pathway to support tumor growth, and certain autoimmune diseases, such as multiple sclerosis, might also respond to TRE-515 treatment. Trethera is developing TRE-515 for use as a monotherapy or in combination, to precisely target a metabolic vulnerability of cancer or autoimmune diseases that will transform outcomes for patients.
