Our team's commitment to execution, supported by a strong balance sheet that provides cash runway into 2028, has positioned Disc to prepare for the potential commercialization of bitopertin and advance pipeline development as we enter the next phase of growth."
Recent Highlights and Anticipated Milestones:
Bitopertin: GlyTI Inhibitor (Heme Synthesis Modulator)
Presented data from HELIOS, an ongoing open-label extension study of bitopertin in EPP, which showed favorable long-term efficacy and safety with sustained protoporphyrin IX (PPIX) reductions, improvement in quality of life, and improved liver biomarkers
Progressing confirmatory Phase 3 APOLLO clinical trial of bitopertin in adults and adolescents with EPP
Completed positive pre-NDA meeting with FDA, confirming alignment with the agency on the expected timing, format, and content of planned NDA submission for bitopertin in EPP
Expect to submit an NDA in October 2025 under the FDA's accelerated approval pathway based on Disc's existing data package
Publication of the results from a preclinical study conducted in collaboration with Boston Children's Hospital showing that, in mice, bitopertin may help prevent liver disease in EPP, in addition to ameliorating blood PPIX levels. The paper, "The GLYT1 inhibitor bitopertin mitigates erythroid PPIX production and liver disease in erythroid protoporphyria," was published in the Journal of Clinical Investigation (corresponding authors Sarah Ducamp and Paul Schmidt)

The increase in R&D expenses was primarily driven by the progression of Disc's portfolio, including bitopertin's clinical studies and drug manufacturing, the advancement of the DISC-0974 program, and increased headcount, as well as a payment of a $10 million milestone upon initiation of the APOLLO study.
Selling, General and Administrative Expenses: SG&A expenses were $15.1 million for the three months ended June 30, 2025, as compared to $7.4 million for the three months ended June 30, 2024. The increase in SG&A expenses was primarily due to increased headcount including establishing infrastructure to support potential commercialization.
Net Loss: Net loss was $55.2 million for the three months ended June 30, 2025, as compared to $26.4 million for the three months ended June 30, 2024. The increase was primarily due to higher operating costs in the current period to support the continued advancement of our pipeline.
