WATERTOWN, Mass., March 21, 2024 (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 reported financial results for the fourth quarter and full year ended December 31, 2023, and provided an update on recent program and corporate developments.

“The past year has been truly remarkable for Disc and marks another important chapter in our company’s story. During 2023, we provided the first evidence of the therapeutic potential of our programs, with positive read-outs in patients for both bitopertin and DISC-0974. In addition, we advanced a third program, DISC-3405, into the clinic and fortified our balance sheet, so we can execute our strategy with confidence,” said John Quisel, J.D., Ph.D., President and Chief Executive Officer of Disc. “These achievements have positioned us well for 2024, which promises to be another transformational year, and I want to express my deep gratitude to our team for their determination and hard work. We’re looking forward to sharing AURORA data in the coming weeks, as well as updated data for DISC-0974 in MF and initial data for DISC-3405 in healthy volunteers in the first half of this year.”

Recent Business Highlights and Upcoming Milestones:

Bitopertin: GlyT1 Inhibitor (Heme Synthesis Modulator)

• Completed enrollment of its phase 2 program of bitopertin in erythropoietic porphyrias:
  • BEACON, an open-label phase 2 clinical study of bitopertin in patients with EPP and X-linked protoporphyria (XLP), which was expanded to include adolescents
  • AURORA a phase 2 randomized, placebo-controlled clinical study of bitopertin in adults with EPP
• Presented positive results from the phase 2 BEACON trial at ASH 2023, showing:
  • Significant, sustained reductions in whole blood protoporphyrin IX (PPIX) levels >40%
  • Robust and consistent improvements across all measures of sunlight tolerance, including >3x improvement over historical control of precedented pivotal endpoint
  • Bitopertin was generally well-tolerated with stable hemoglobin at both dose levels
• Topline AURORA data planned for press release and corporate presentation in March/April 2024

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

• Presented positive, initial data from ongoing phase 1b/2 clinical study in MF patients with severe anemia at ASH 2023:
  • Treatment at initial dose levels (14 mg, 28 mg, 50 mg) resulted in substantial, dose-dependent decreases in hepcidin and increases in serum iron
  • Hematologic activity was observed in MF patients, regardless of concomitant JAK inhibitor use. Four of seven (57%) evaluable non-transfusion-dependent (NTD) patients reached a >1.5g/dL hemoglobin increase and one of two transfusion-dependent (TD) patients achieved transfusion independence.
  • DISC-0974 was generally well-tolerated
  • Enrollment and dose escalation is ongoing
• Presented initial data from the 28 mg cohort of the ongoing phase 1b/2 clinical study of patients with anemia of chronic kidney disease who are not receiving dialysis (NDD-CKD)
  • Data demonstrated meaningful reductions in serum hepcidin and corresponding increases in serum iron with a similar PK/PD profile as seen in Disc’s healthy volunteer study
  • Enrollment and dose escalation is ongoing
• Updated phase 1b/2 data from DISC-0974 in anemia in MF patients is expected to be presented in the first half of 2024
• Updated phase 1b/2 data from DISC-0974 in anemia in NDD-CKD is expected to be shared in the second half of 2024
• Received FDA fast track designation in February 2024 for DISC-0974 for the treatment of anemia in NDD-CKD
  
  

DISC-3405: Anti-TMPRSS6 Antibody (Hepcidin Induction)

• Initiated a phase 1 SAD / MAD study in healthy volunteers in October 2023
• Initial SAD data expected to be presented in the first half of 2024
• Received FDA orphan drug designation in February 2024 for DISC-3405 for the treatment of PV
  
  

Corporate:

• As the company enters late-stage development and begins planning for commercialization, Disc expanded its leadership team with the appointments of industry veterans Jean Franchi as Chief Financial Officer and Pamela Stephenson as Chief Commercial Officer, and the promotion of Jonathan Yu to Chief Operating Officer
  
  

Full Year 2023 Financial Results:

• Cash Position: Cash and cash equivalents were $360.4 million as of December 31, 2023, which are expected to fund our operational plans well into 2026, compared to $194.6 million as of December 31, 2022. The increase was primarily due to the completion of a registered direct offering in February 2023 and a publicly marketed follow-on offering in June 2023.
• Research and Development Expenses: R&D expenses were $69.3 million for the full year ended December 31, 2023, as compared to $33.4 million for the full year ended December 31, 2022. The increase in R&D expenses were primarily driven by the progression of Disc’s portfolio, including bitopertin’s ongoing two phase 2 clinical studies and drug manufacturing, phase 1 study initiation for DISC-3405, and increased headcount.
• General and Administrative Expenses: G&A expenses were $21.9 million for the full year ended December 31, 2023, as compared to $14.0 million for the full year ended December 31, 2022. The increase in G&A expenses was primarily due to increased headcount and increased costs as a public company.
• Net Loss: Net loss was $76.4 million for the full year ended December 31, 2023, as compared to $46.8 million for the full year ended December 31, 2022. The increase was primarily due to higher operating costs in the current period to support the continued advancement of our pipeline.
