IRON Disc Medicine Inc

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 reported financial results for the full year ended December 31, 2022 and business highlights.

“2022 was a year of transformation and tremendous achievement for Disc. During the past year, we became a publicly-traded company through our reverse merger with Gemini Therapeutics, strengthened our balance sheet, and advanced both bitopertin and DISC-0974 into patient studies. This puts us in a strong position for growth in 2023, when we anticipate our first data readouts in patients and will continue to execute on our vision of building a leading hematology franchise,” said John Quisel, J.D., Ph.D., President and Chief Executive Officer of Disc. “In this past quarter, we have already expanded our pipeline by in-licensing a third, Phase 1-ready program, further strengthened our financial position with a registered direct offering led by Bain Capital Life Sciences, and initiated a Phase 1b/2 study of DISC-0974 in patients with CKD anemia. I want to thank the Disc team for their tireless efforts as we look forward to another exciting year in 2023.”

Business Highlights and Anticipated Milestones:

Bitopertin: GlyT1 Inhibitor (Heme Synthesis Modulator)

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.

• In August 2022, Disc initiated BEACON, an open-label Phase 2 clinical study of bitopertin in patients with EPP and X-linked protoporphyria (XLP). Disc expects to present interim data in the first half of 2023.
• In October 2022, Disc initiated AURORA, a Phase 2 randomized, placebo-controlled clinical study of bitopertin in adults with EPP. Disc expects topline data by year-end 2023.
• In December 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation to bitopertin for the treatment of EPP. In January 2023, the European Committee for Orphan Medical Products adopted a positive opinion on Orphan Designation for bitopertin for treatment of EPP.
• In March 2023, Disc announced a collaboration with NIH to study bitopertin in patients with Diamond-Blackfan Anemia; the study is expected to initiate in mid-year 2023.

DISC-0974: Anti-Hemojuvelin Antibody (Hepcidin Suppression)

DISC-0974 is an investigational anti-hemojuvelin monoclonal antibody (mAb) and is designed to suppress hepcidin production and increase serum iron levels in patients suffering from anemia of inflammation.

• Successful completion of the first-in-human, Phase 1 SAD study in healthy volunteers, demonstrating suppressed hepcidin and improvements in serum iron, hemoglobin, and other hematologic parameters.
• Data from the Phase 1 study were presented at the European Hematology Association Annual Congress and the American Society of Hematology Annual Meeting.
• Initiated a Phase 1b/2 clinical study in MF patients with severe anemia who may or may not be receiving concomitant treatment with JAK inhibitors; interim data expected at the end of 2023.
• In February 2023, Disc initiated a Phase 1b/2 clinical study of patients with anemia of chronic kidney disease who are not receiving dialysis (NDD-CKD); interim data expected at the end of 2023.

MWTX-003: Anti-TMPRSS6 Antibody (Hepcidin Induction)

MWTX-003 is an investigational, anti-TMPRSS6 (Transmembrane Serine Protease 6, also known as Matriptase-2) monoclonal antibody designed to increase hepcidin production and suppress serum iron.

• In January 2023, Disc entered into an exclusive licensing agreement with Mabwell Therapeutics to obtain an exclusive license to rights outside of Greater China for a portfolio of monoclonal antibodies targeting TMPRSS6 including a Phase 1-ready drug candidate, MWTX-003.
• Preclinical studies of MWTX-003 have demonstrated an increase in hepcidin production and suppression of serum iron levels in various animal models of beta-thalassemia and polycythemia vera.
• The IND was accepted in November 2022 and Disc plans to initiate a Phase 1 study of MWTX-003 in healthy volunteers during the second half of 2023.
• Disc plans to develop MWTX-003 initially as a treatment for polycythemia vera as well as other indications.

Corporate:

• Disc completed a reverse merger with Gemini Therapeutics in December 2022, which resulted in Disc becoming publicly listed on NASDAQ, and raised approximately $90 million in operating capital. Concurrent with the merger, Disc completed a financing of $53.5 million from a syndicate of healthcare investors led by Access Biotechnology and including OrbiMed, Atlas Venture, 5AM Ventures, Novo Holdings A/S, Arix Bioscience, Rock Springs Capital, and Janus Henderson Investors.
• In February 2023, Disc completed a $62.5 million registered direct offering led by Bain Capital Life Sciences, with participation from Access Biotechnology and OrbiMed.

Full Year 2022 Financial Results:

• Cash Position: Cash and cash equivalents were $194.6 million as of December 31, 2022 compared to $88.0 million as of December 31, 2021. The increase was due to the completion of the reverse merger with Gemini Therapeutics and the concurrent financing, which was completed on December 29, 2022. In February 2023, Disc subsequently completed a registered direct offering in the amount of $62.5 million led by Bain Capital Life Sciences. Disc expects these combined cash and cash equivalents to fund its operational plans into 2025.
• Research and Development Expenses: R&D expenses were $33.4 million for the full year ending December 31, 2022, as compared to $25.2 million for the full year ending December 31, 2021. The increase in R&D expenses were primarily driven by the progression of Disc’s portfolio, including increased headcount, the advancement of DISC-0974 into a Phase 1b/2 clinical study, and bitopertin into two Phase 2 clinical studies.
• General and Administrative Expenses: G&A expenses were $14.0 million for the full year ending December 31, 2022, as compared to $5.8 million for the full year ending December 31, 2021. The increase in G&A expenses was primarily due to increased headcount and costs associated with a planned equity financing that was superseded by the Gemini reverse merger.
• Net Loss: The net loss was $46.8 million for the year ended December 31, 2022, as compared to $36.0 million for the full year ending December 31, 2021. The increase was primarily due to higher operating costs in the current period to support the continued advancement of the Company’s pipeline.
