Disc Medicine Announces Presentation of Initial Data from Phase 2 BEACON Trial in Patients with Erythropoietic Protoporphyria (EPP) at European Hematology Association (EHA) 2023 Congress

WATERTOWN, Mass., May 11, 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 upcoming clinical data to be presented at the European Hematology Association (EHA) 2023 Congress in Frankfurt, Germany. The presentation will report initial results from BEACON, the Phase 2, randomized, open‐label, parallel arm trial of bitopertin in Erythropoietic Protoporphyria (EPP) that is ongoing in Australia. This study was designed to assess changes in levels of protoporphyrin IX (PPIX), the toxic metabolite that causes disease pathology in EPP, as well as measures of photosensitivity, quality of life, and safety and tolerability. 

Additionally, an abstract outlining the study design of AURORA, a Phase 2, randomized double-blind, placebo-controlled trial of bitopertin in EPP will be published in the EHA Abstract Book.

Both abstracts are now available on the EHA conference website.

Management will host a call to review the presented data on Friday, June 9^th at 7:30 am ET. Please register for the event on the Events and Presentations page of Disc’s website (https://ir.discmedicine.com/).

Abstract Number: P1498
Title: Initial Data from the BEACON Trial: A Phase 2, Randomized, Open‐label Trial of Bitopertin in Erythropoietic Protoporphyria
Date / Time: Friday, June 9^th, 18:00-19:00 CEST

Abstract Number: PB2562
Title: Study Design of the AURORA Trial: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Trial of Bitopertin in Erythropoietic Protoporphyria

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 studies 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 20-30% of patients and in extreme cases liver failure. Current standard of care involves extreme measures to avoid sunlight, including restricting outdoor activities to nighttime, use of protective clothing and opaque shields, and pain management. This has a significant impact on the psychosocial development, quality of life, and daily activities of patients, particularly in young children and families. There is currently no cure for EPP and only one FDA-approved therapy, a surgically implanted synthetic hormone designed to stimulate melanin production called Scenesse® (afamelanotide).

About Disc Medicine
Disc Medicine is a clinical-stage biopharmaceutical company committed to discovering, developing, and commercializing novel treatments for patients who suffer from serious hematologic diseases. We are building a portfolio of innovative, potentially first-in-class therapeutic candidates that aim to address a wide spectrum of hematologic diseases by targeting fundamental biological pathways of red blood cell biology, specifically heme biosynthesis and iron homeostasis.
