On August 10, 2022, Gemini Therapeutics, Inc. (Nasdaq: GMTX) ("Gemini") and Disc Medicine, Inc. ("Disc"), announced that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on advancing Disc's pipeline of hematology programs, including multiple clinical trials for its clinical-stage programs bitopertin and DISC-0974. Upon shareholder approval, the combined company is expected to operate under the name Disc Medicine, Inc. and trade on the Nasdaq Global Market under the ticker symbol IRON. The merger and related financing are expected to close in the fourth quarter of 2022.

Disc has a development pipeline composed of investigational product candidates that affect heme biosynthesis and iron metabolism. Disc's programs are designed to target pathways with established, clinically-validated biology and have the potential to address multiple indications. This includes:

Bitopertin (Heme Synthesis Modulator): Bitopertin is an investigational, orally administered inhibitor of glycine transporter 1, GlyT1. Bitopertin was in-licensed by Disc from Roche in 2021 and has previously demonstrated tolerability and effects on heme biosynthesis in over 4,000 individuals across multiple clinical trials. Inhibition of heme biosynthesis has the potential to address a wide range of hematologic disorders. Disc recently initiated AURORA, a randomized, double-blind, placebo-controlled Phase 2 trial of bitopertin in patients with EPP, a rare, debilitating and potentially fatal genetic disorder that results in dysregulated heme biosynthesis and where bitopertin has the potential to become the first disease-modifying treatment. Bitopertin is also currently being studied in BEACON, an open-label Phase 2 clinical trial in patients with EPP and X-linked protoporphyria (XLP), which was initiated in August 2022 and is being conducted in Australia. Additional clinical trials in Diamond-Blackfan Anemia (DBA) and other indications are being planned.

DISC-0974 (Hepcidin Suppression): DISC-0974 is an investigational monoclonal antibody (mAb) targeting a BMP-signaling co-receptor called hemojuvelin (HJV) and is designed to suppress hepcidin production and increase serum iron levels in patients suffering from anemia of inflammation. DISC-0974 was in-licensed by Disc from AbbVie in 2019. Anemia of inflammation arises from abnormally elevated hepcidin and is the most common form of anemia, affecting millions of patients in the US across numerous diseases such as chronic kidney disease, myelofibrosis, cancer, autoimmune diseases, and other conditions with an inflammatory component. Disc has established clinical proof-of-mechanism of DISC-0974 in a Phase 1 trial of healthy volunteers and initiated a Phase 1b/2a clinical trial of DISC-0974 in patients with myelofibrosis and anemia. Disc plans to initiate a Phase 1b/2a clinical trial of DISC-0974 in patients with chronic kidney disease and anemia in late 2022.

DISC-0998: DISC-0998 is an investigational anti-HJV mAb with an engineered Q and L mutation (QL-mutation) in the Fc region, aimed to alter binding to the FcRn receptor, resulting in an increased PK half-life. Preclinical studies have demonstrated that DISC-0998 has shown biological activity, low immunogenicity potential, and desirable pharmacokinetic (PK) and pharmacodynamic (PD) properties in monkeys. The company will present data in cynomolgus monkeys at the 64th ASH Annual Meeting and Exposition that allow for the prediction of PK/PD profiles in humans and support further development of DISC-0998 for anemia of inflammation related disorders with the potential of long intervals in between dosing.

Matriptase-2 Inhibitor (Hepcidin Induction): Disc has a preclinical research program designed to identify orally available, small molecules to inhibit Matriptase-2 (referred to as Mat-2 or TMPRSS6) and increase the production of hepcidin and restrict iron availability. The therapeutic role of hepcidin has been established by third parties in patients with polycythemia vera (PV) and hereditary hemochromatosis. Disc is initially focused on developing its Mat-2 program as a potential treatment for PV, diseases of iron overload, and other conditions where restriction of iron would have therapeutic benefit.
