Form Type
8-K

Rhea-AI Filing Summary

Disc Medicine reported second-quarter 2026 results and highlighted progress across its hematology pipeline. A Type A meeting with the FDA confirmed that the Phase 3 APOLLO study of bitopertin in erythropoietic protoporphyria can, if successful, serve as the basis for a CRL response and could potentially support traditional approval, with topline APOLLO data expected in Q4 2026. The company also launched an Expanded Access Program for bitopertin and reported sustained efficacy and safety from the HELIOS extension trial.

For selcodebart (DISC-0974), updated Phase 2 RALLY-MF data in myelofibrosis showed a 56% Major anemia response rate and 72% overall anemia response rate, and the program received EU Orphan Drug Designation. Disc completed enrollment in the Phase 2 RESTORE-PV study of DISC-3405 in polycythemia vera, with initial data expected in Q3 2026, and is progressing a Phase 1b sickle cell disease study with data expected in Q4 2026.

Disc ended Q2 2026 with approximately $718 million in cash, cash equivalents, and marketable securities, which it expects to fund operations into 2029. Second-quarter research and development expenses were $46.9 million, selling, general and administrative expenses were $18.1 million, and net loss was $59.5 million, or $(1.54) per share.

Positive

  • Alignment with the FDA that the APOLLO Phase 3 trial of bitopertin can, if successful, serve as the basis for a CRL response, together with approximately $718 million in cash providing runway into 2029, clarifies both the registrational path and funding horizon.

Negative

  • None.

Filing Explained

At June 30, cash, cash equivalents, and marketable securities were $717.7 million, down from $791,152 thousand at December 31, 2025.

This July 30 Form 8-K furnishes Disc Medicine’s second-quarter results and corporate update; the disclosed balance sheet shows a lower liquidity balance, while no new ownership or dilution mechanics are reported.

Form 8-K is used to report specified material events, and this report’s Item 2.02 information, including its press-release exhibit, is furnished rather than filed for Exchange Act liability purposes.

At June 30, 2026, cash, cash equivalents, and marketable securities were $717.7 million, versus $791,152 thousand at December 31, 2025; total liabilities rose from $67,053 thousand to $90,907 thousand, while stockholders’ equity fell from $739,826 thousand to $644,164 thousand.

The company says the June 30 liquidity balance is expected to fund operations into 2029, but that statement is a forward-looking expectation rather than a completed financing or a receipt of new proceeds.

RALLY-MF anemia response rates 56% Major, 72% overall Major anemia response and overall anemia response across evaluable myelofibrosis patients
Type A meeting regulatory
"Completed Type A meeting with the FDA on bitopertin and aligned"
A Type A meeting is an urgent, short-notice session requested between a company and a regulatory agency (for example, the FDA in the U.S.) to resolve critical issues that block a development program, such as a clinical hold or safety concern. Investors care because the outcome can immediately affect whether a clinical trial or approval process resumes, changing timelines, costs and the company’s near-term value — like calling an emergency mechanic when a car won’t start so a trip can continue.
CRL regulatory
"serve as the basis for CRL response and could potentially support"
A CRL, or Complete Response Letter, is a formal notice from a drug regulator saying a drug application cannot be approved in its current form and lists what problems must be fixed. Think of it like a building inspector issuing a list of required repairs before a certificate of occupancy is granted. For investors, a CRL can delay or reduce the commercial value of a drug, affecting a company’s timeline, costs and stock outlook.
Expanded Access Program (EAP) regulatory
"Launched an Expanded Access Program (EAP) for bitopertin in the US"
An expanded access program (EAP) lets people with serious or life‑threatening conditions use a drug or therapy that has not yet received full approval, when they cannot join clinical trials. Think of it like giving a small group early access to a product still under review; for investors it matters because EAPs can reveal real‑world safety or effectiveness signals, affect public perception and regulatory review, and provide limited early demand indicators that influence a company’s risk and value.
Orphan Drug Designation regulatory
"Received EU Orphan Drug Designation for selcodebart for the treatment"
Orphan drug designation is a special status given to medicines developed to treat rare diseases affecting only a small number of people. This status often provides benefits like faster approval processes and financial incentives, making it more attractive for companies to develop these drugs. For investors, it signals potential for exclusive market rights and reduced competition, which can impact the drug’s profitability.
Major anemia response rate medical
"Data showed Major anemia response rate of 56% and overall anemia"
hepcidin medical
"Anti-Hemojuvelin Antibody (Hepcidin Suppression) and Anti-TMPRSS6 Antibody (Hepcidin Induction)"
Hepcidin is a small hormone produced by the liver that acts like a thermostat for the body's iron supply, telling the gut and storage sites when to absorb, release or hold onto iron. Investors watch hepcidin because drugs, tests or diagnostics that change its levels can treat common conditions such as anemia or iron overload, making them potential revenue drivers and regulatory milestones in healthcare markets.
Net loss (Q2 2026) $59.5 million Compared with $55.2 million in Q2 2025
Net loss per share (Q2 2026) $(1.54) Compared with $(1.58) in Q2 2025

Launched Expanded Access Program (EAP) for bitopertin for eligible erythropoietic protoporphyria (EPP) patients
Presented positive clinical data updates from the RALLY-MF Phase 2 trial of selcodebart (DISC-0974) in anemia of myelofibrosis and the HELIOS open-label extension trial of bitopertin in EPP
Completed enrollment for RESTORE-PV Phase 2 study of DISC-3405 in polycythemia vera (PV) with initial data expected in Q3 2026 and progressing Phase 1b study of DISC-3405 in sickle cell disease (SCD) with initial data expected in Q4 2026
Strong financial position ending Q2 with approximately $718 million in cash, cash equivalents, and marketable securities, providing runway into 2029

WATERTOWN, Mass., July 30, 2026 – 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 second quarter ended June 30, 2026, and provided a review of recent program and corporate developments.

“The anticipated readout of the Phase 3 APOLLO trial of bitopertin in EPP in Q4 marks a significant milestone. We have continued driving forward on this program over the past quarter with the launch of our EAP,” said John Quisel, J.D., Ph.D., Chief Executive Officer and President of Disc. “We also look forward to significant advancement across the rest of our pipeline in the second half of 2026. We saw strong demand for the Phase 2 RESTORE-PV trial of DISC-3405 in polycythemia vera, which is now fully enrolled with initial data coming ahead of schedule in Q3. Along with an expected end of Phase 2 FDA interaction on selcodebart in MF anemia in Q4, we will potentially be positioned to advance two more programs into pivotal-stage development in 2027.”

Recent Highlights and Anticipated Milestones:

Bitopertin: GlyT1 Inhibitor (Heme Synthesis Modulator)

Completed Type A meeting with the FDA to discuss the CRL for bitopertin in erythropoietic protoporphyria (EPP) and aligned that the Phase 3 APOLLO study, if successful, can serve as the basis for CRL response and could potentially support a traditional approval
Presented updated data from the HELIOS open-label extension trial of bitopertin in EPP at the European Hematology Association (EHA) Annual Meeting, demonstrating sustained reductions in protoporphyrin IX (PPIX), significant improvement in light tolerance measures, and favorable longer-term safety
Launched an Expanded Access Program (EAP) for bitopertin in the US and select other geographies, providing eligible patients with EPP and XLP access to treatment prior to a regulatory decision
On track to report APOLLO topline results in Q4 2026 and expect to submit CRL response and receive an FDA decision by mid-2027
o
APOLLO completed enrollment in March 2026 and enrolled ahead of schedule with a final N of 183

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

Shared updated data from RALLY-MF trial of selcodebart in anemia of myelofibrosis (MF) in oral presentations at the American Society of Clinical Oncology (ASCO) and European Hematology Association (EHA) annual meetings, solidifying selcodebart’s differentiated emerging profile in MF. Data showed:

img57926557_0.jpg

 

 

o
Major anemia response rate of 56% and overall anemia response rate of 72% across evaluable patients
o
Similar, strong response rates across transfusion cohorts and with or without background JAK inhibitor therapy
Additional data from RALLY-MF anticipated in Q4 2026, with an end-of-Phase 2 meeting with the FDA expected to occur by year-end
Received EU Orphan Drug Designation for selcodebart for the treatment of myelofibrosis
Progressing Phase 2 study in patients with inflammatory bowel disease (IBD) with initial data expected in 2027

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

Completed enrollment for RESTORE-PV Phase 2 study in patients with polycythemia vera with initial data expected in Q3 2026
Progressing Phase 1b study in patients with sickle cell disease with initial data expected in Q4 2026

Second Quarter 2026 Financial Results:

Cash Position: Cash, cash equivalents, and marketable securities were $717.7 million as of June 30, 2026, which are expected to fund operational plans into 2029.
Research and Development Expenses: R&D expenses were $46.9 million for the three months ended June 30, 2026, as compared to $46.3 million for the three months ended June 30, 2025. The increase in R&D expenses was primarily driven by the progression of Disc's portfolio, including the advancement of the selcodebart (DISC-0974) and DISC-3405 clinical studies and drug manufacturing, as well as increased headcount. These increases were partially offset by a decrease in manufacturing costs related to bitopertin and a $10.0 million milestone payment incurred upon initiation of the APOLLO study during the comparative period.
Selling, General and Administrative Expenses: SG&A expenses were $18.1 million for the three months ended June 30, 2026, as compared to $15.1 million for the three months ended June 30, 2025. The increase in SG&A expenses was primarily due to increased headcount.
Net Loss: Net loss was $59.5 million for the three months ended June 30, 2026, as compared to $55.2 million for the three months ended June 30, 2025. The increase was primarily due to higher operating costs in the current period to support the continued advancement of our pipeline.
