ROCKVILLE, Md., March 09, 2026 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (NASDAQ:MGNX), a clinical-stage biopharmaceutical company focused on developing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress, reported financial results for the year ended December 31, 2025, and highlighted anticipated data disclosure timelines for its product pipeline.

"I am excited about MacroGenics' future prospects, and am inspired by the commitment of our employees over the past few quarters to sharpen our focus and advance our strategic priorities," said Eric Risser, President and CEO of MacroGenics. "Looking ahead, we anticipate several important milestones in 2026, including initial clinical data from the Phase 1 studies of MGC026 and MGC028, and from the LINNET study of lorigerlimab. Additionally, we plan to submit an IND for MGC030, a first-in-class topoisomerase I inhibitor-based ADC. Finally, with cash runway into late 2027, we believe we are well positioned to execute on our plan and drive meaningful value for our shareholders."

Corporate Progress and Anticipated Milestones

Innovative ADC Pipeline

MacroGenics is developing potential best-in-class or first-in-class antibody-drug conjugates (ADCs) that leverage its protein engineering expertise and incorporate potent glycan-linked exatecan payloads designed to enable an expanded therapeutic window. The proprietary drug-linker platform is licensed from Synaffix B.V., a Lonza company.

MacroGenics' two clinical-stage ADC programs, MGC026 and MGC028, have demonstrated acceptable safety profiles to date, with no observations of interstitial lung disease, as well as encouraging early evidence of anti-tumor activity by Response Evaluation Criteria in Solid Tumors (RECIST).

MGC026 targets B7-H3, an antigen with broad expression across multiple solid tumors and a member of the B7 family of molecules involved in immune regulation. The Company completed enrollment of a Phase 1 dose escalation study in 2025 and is currently enrolling patients in a dose expansion study in selected solid tumor indications. The Company anticipates reporting initial MGC026 clinical data in mid-2026.
MGC028 is a first-in-class ADC that targets ADAM9, a member of the ADAM family of multifunctional type 1 transmembrane proteins that play a role in tumorigenesis and cancer progression and is overexpressed in multiple solid tumors. MGC028 is currently being evaluated in a Phase 1 dose escalation study in patients with advanced solid tumors. The Company anticipates reporting initial MGC028 clinical data in the second half of 2026.
MGC030 is a first-in-class preclinical ADC that targets an undisclosed antigen expressed across several solid tumors. An Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for MGC030 is planned for the third quarter of 2026.

Lorigerlimab

The LINNET study is a Phase 2 monotherapy trial evaluating lorigerlimab, a PD-1 × CTLA-4 bispecific DART® molecule, in patients with either platinum-resistant ovarian cancer (PROC) or clear cell gynecologic cancer (CCGC). As previously announced, the FDA has placed a partial clinical hold on the LINNET study, and no new patients are being enrolled while the hold remains in effect. MacroGenics is working closely with the FDA to resolve the partial clinical hold as soon as possible. MacroGenics continues to plan for a clinical update in mid-2026.

Partnership Updates

Gilead. MacroGenics and Gilead are advancing three programs, including (1) MGD024, a clinical-stage CD123 × CD3 bispecific DART molecule being evaluated in an ongoing dose escalation study in AML and MDS, (2) a preclinical TRIDENT® molecule program, and (3) a preclinical DART molecule program. The Company remains eligible to receive up to $1.6 billion in future milestones as well as royalties related to these three product candidates.
Sanofi. Sanofi is progressing the worldwide development and commercialization of TZIELD® (teplizumab-mzwv), an antibody targeting CD3 that the Company sold in 2018 to a partner that was subsequently acquired by Sanofi S.A. (Sanofi). In October 2025, Sanofi announced that TZIELD had been accepted for expedited review in the U.S. for stage 3 type 1 diabetes through the FDA Commissioner's National Priority Voucher pilot program. MacroGenics remains eligible to receive up to $330 million in additional milestones related to TZIELD.
Incyte. Incyte is progressing the worldwide development and commercialization of ZYNYZ® (retifanlimab-dlwr), a humanized PD-1 antibody originally developed in collaboration with MacroGenics that is approved in the U.S. for the treatment of metastatic or recurrent locally advanced Merkel cell carcinoma and for first-line and subsequent-line treatment of advanced squamous cell carcinoma of the anal canal (SCAC). In December 2025, Japan's Ministry of Health, Labour and Welfare approved ZYNYZ as first-line therapy for adults with locally recurrent or metastatic SCAC. In addition, Incyte recently disclosed that the European Commission approved ZYNYZ in combination with carboplatin and paclitaxel for the first-line treatment of adult patients with metastatic or inoperable locally recurrent SCAC. MacroGenics remains eligible to receive up to $540 million in additional milestones related to ZYNYZ.

2025 Financial Results

Cash Position: Cash, cash equivalents and marketable securities balance as of December 31, 2025, was $189.9 million, compared to $201.7 million as of December 31, 2024.
Revenue: Total revenue was $149.5 million for the year ended December 31, 2025, compared to $150.0 million for the year ended December 31, 2024. Total revenue included contract manufacturing revenue of $52.6 million for the year ended December 31, 2025, compared to $13.1 million for the year ended December 31, 2024, reflecting increased production for external clients in 2025.
R&D Expenses: Research and development expenses were $147.2 million for the year ended December 31, 2025, compared to $177.2 million for the year ended December 31, 2024. The decrease was primarily attributable to decreased costs related to programs that were terminated or sold as well as decreased manufacturing and IND-enabling costs related to MGC028, partially offset by increased clinical trial costs related to MGC026 and MGC028 as well as increased development costs related to MGC030.
Cost of Manufacturing Services: Cost of manufacturing services was $36.0 million for the year ended December 31, 2025, compared to $11.5 million for the year ended December 31, 2024. The increase was due to increased production for external clients in 2025.
SG&A Expenses: Selling, general and administrative expenses were $39.2 million for the year ended December 31, 2025, compared to $71.0 million for the year ended December 31, 2024. The decrease was primarily due to lower stock-based compensation expense and reduced professional fees.
Net Loss: Net loss was $74.6 million for the year ended December 31, 2025, compared to $67.0 million for the year ended December 31, 2024, which included a $36.3 million gain on sale of MARGENZA®.
Shares Outstanding: Shares of common stock outstanding as of December 31, 2025, were 63,318,613.
Cash Runway Guidance: MacroGenics anticipates that its cash, cash equivalents and marketable securities balance of $189.9 million as of December 31, 2025, in addition to anticipated and future payments from partners and anticipated savings from the Company's cost-reduction initiatives, is expected to support its cash runway into late 2027.
