WATERTOWN, Mass., Nov. 14, 2023 (GLOBE NEWSWIRE) -- Disc Medicine, Inc. (NASDAQ:IRON), a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of novel treatments for patients suffering from serious hematologic diseases, today announced that the United States Patent and Trademark Office (USPTO) has issued patent No. 11,813,257 for methods of treating erythropoietic protoporphyrias (EPPs) with glycine transport inhibitors.
“We are pleased to have been issued this patent that further secures IP protection for bitopertin for the treatment of erythropoietic protoporphyria as we work to deliver a potentially transformative therapy to patients,” said John Quisel, J.D., Ph.D., President and Chief Executive Officer of Disc. “This patent further highlights the innovative approach we are taking to treat EPP, as demonstrated by the data we shared in June, which we will update at ASH in December.”
This patent covers uses of bitopertin, a glycine transport inhibitor, in treating erythropoietic protoporphyria (EPP) or X-linked protoporphyria (XLP) with an anticipated expiration in 2041, before any available term extensions or adjustments. Disc intends to continue to prosecute additional patent applications to support use of bitopertin in treating hematologic disorders.
About Bitopertin
Bitopertin is an investigational, clinical-stage, orally-administered inhibitor of glycine transporter 1 (GlyT1) that is designed to modulate heme biosynthesis. GlyT1 is a membrane transporter expressed on developing red blood cells and is required to supply sufficient glycine for heme biosynthesis and support erythropoiesis. Disc is planning to develop bitopertin as a potential treatment for a range of hematologic diseases including erythropoietic porphyrias, where it has potential to be the first disease-modifying therapy. There are currently two ongoing Phase 2 clinical trials of bitopertin in patients with erythropoietic porphyria, including an open-label trial called BEACON and a randomized, double-blind placebo-controlled trial called AURORA.
Bitopertin is an investigational agent and is not approved for use as a therapy in any jurisdiction worldwide. Disc obtained global rights to bitopertin under a license agreement from Roche in May 2021.
About Erythropoietic Protoporphyria (EPP) and X-linked Protoporphyria (XLP)
Erythropoietic protoporphyria (EPP) and X-linked Protoporphyria (XLP) are rare, debilitating and potentially life-threatening diseases caused by mutations that affect heme biosynthesis, resulting in the accumulation of a toxic, photoactive intermediate called protoporphyrin IX (PPIX). This causes severe reactions when patients are exposed to sunlight, characterized by excruciating pain, edema, burning sensations and potential blistering and disfigurement. PPIX also accumulates in the hepatobiliary system and can result in complications including gallstones, cholestasis, and liver damage in 20
