Disc Medicine, Inc. is a clinical-stage biotechnology company based in Watertown, Massachusetts. The company leverages deep expertise in red blood cell biology to address unmet medical needs in hematology, positioning itself as an innovator in the development of therapies for rare blood diseases. Its strategic focus on fundamental biological pathways and targeted drug development provides a competitive edge within the biotechnology sector.
This 650,000-share position was established during the fourth quarter, before the FDA issued its Complete Response Letter in February and before the roughly 20% one-day selloff that followed. That timing matters. The investment case was likely built on the science and balance sheet, not on a rebound trade.
The FDA acknowledged that bitopertin lowered PPIX in EPP patients but concluded the existing data did not sufficiently demonstrate a correlation with clinical outcomes. The agency pointed to the ongoing Phase 3 APOLLO trial as the path forward, with topline data expected in the fourth quarter. Management expects a potential updated FDA decision by mid 2027 if results support approval. Importantly, Disc ended 2025 with approximately $791 million in cash and marketable securities and guides runway into 2029.
Within a portfolio anchored by high conviction biotech names like Kymera, Revolution Medicines, and MoonLake, this fits a familiar pattern of concentrated exposure to differentiated platforms with binary catalysts. Ultimately, it looks like the thesis timeline may have stretched for Disc Medicine, and the thesis now rests squarely on APOLLO data and capital durability.
