ROCKVILLE, Md., Aug. 13, 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 reported financial results for the quarter ended June 30, 2026, and highlighted its recent corporate and pipeline progress.

“Our team delivered strong second-quarter execution: advancing our strategic priorities, strengthening our financial position, and sharpening our focus to accelerate the development of life-changing medicines for patients,” said Eric Risser, President and Chief Executive Officer of MacroGenics. “With a significantly stronger financial foundation, we are well-positioned to advance our pipeline and deliver a catalyst-rich period ahead.”

Advancement of Innovative Pipeline

MacroGenics is developing a portfolio of investigational agents, including both topoisomerase I inhibitor-based antibody-drug conjugates (ADCs) and T-cell engagers (TCEs).

• MGC026 is a novel ADC targeting B7-H3, a protein expressed across the tumor microenvironment, including tumor-associated stroma and vasculature. The dose-escalation portion of the ongoing Phase 1 study has been completed after evaluating doses ranging from 1 mg/kg to 9 mg/kg every three weeks (Q3W). A dose of 7.5 mg/kg Q3W is being further evaluated in four tumor-specific cohorts, including squamous cell carcinoma of the head and neck (SCCHN), endometrial cancer, melanoma and soft tissue sarcoma. MGC026 recently achieved an important milestone, with the SCCHN cohort meeting the pre-specified response threshold to advance into Stage 2. Interim results from the Phase 1 study have been accepted for poster presentation at the European Society for Medical Oncology (ESMO) 2026 Congress in October.
• MGC028 is a first-in-class ADC targeting ADAM9, a protein that is overexpressed in multiple solid tumors. The dose escalation study of MGC028 is ongoing and the Company anticipates providing an update with preliminary clinical results in late 2026.
• MGC030 is a first-in-class ADC targeting an undisclosed antigen expressed across several solid tumors. The Company’s Investigational New Drug (IND) application was submitted ahead of schedule and cleared by the U.S. Food and Drug Administration (FDA) in the second quarter of 2026. The Company plans to commence a Phase 1 dose escalation study in the third quarter of 2026.
• Lorigerlimab is a PD-1 × CTLA-4 bispecific DART® molecule being evaluated in patients with advanced gynecologic cancers. MacroGenics continues the Phase 2 LINNET study of lorigerlimab, with the interim data accepted for poster presentation at the ESMO 2026 Congress. The Company is enrolling 20 additional patients with clear cell gynecologic cancer (CCGC) at a dose of 3 mg/kg Q3W and anticipates reporting updated study results in the first half of 2027.
  
  

Future Pipeline

MacroGenics is advancing multiple preclinical programs that incorporate proprietary platforms for next-generation TCEs and ADCs. Following completion of preclinical proof-of-concept studies and preliminary toxicology in non-human primates, the Company recently nominated MGD032, a novel next-generation TCE against an undisclosed target. This molecule is now advancing in IND-enabling studies.

Partnership Updates

MacroGenics maintains partnerships with Incyte Corporation, Sanofi and Gilead Sciences, Inc. spanning multiple commercial, clinical and preclinical programs. Through these collaborations, the Company remains eligible to receive up to approximately $2.4 billion in aggregate future milestone payments, in addition to potential royalties on net product sales.

On August 11, the Company announced that Gilead had exercised its option to license a preclinical bispecific program under the companies’ 2022 collaboration agreement. This option exercise triggers a $10.0 million payment to MacroGenics. The Company remains eligible to earn additional milestones and royalties based on net product sales.

Corporate Update

Corporate Restructuring and Divestiture of Manufacturing Operations. In July, MacroGenics announced the completion of the sale of its GMP drug substance manufacturing operations to Bora Pharmaceuticals Co., Ltd. and Bora Biologics USA, LLC (collectively, Bora) for a previously disclosed base purchase price of $122.5 million. At closing, the Company received $119.6 million in cash consideration, reflecting adjustments for net working capital and indebtedness, before transaction fees and expenses. Approximately 140 previous MacroGenics employees were hired by Bora and, together with a concurrent restructuring, MacroGenics’ workforce is anticipated to be reduced to approximately 140 employees by year-end. As part of the transaction, MacroGenics entered into a supply agreement with Bora to support process development and drug substance production for the Company’s internal pipeline. MacroGenics’ transition to a fully-outsourced manufacturing model and a leaner organization is expected to enable greater focus on the advancement of its novel therapeutics pipeline, while providing increased flexibility and cost effectiveness.

Second Quarter 2026 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities as of June 30, 2026, were $173.3 million, compared with $189.9 million as of December 31, 2025. The balance as of June 30, 2026, included $60.0 million received from Sagard Healthcare Partners related to the monetization of ZYNYZ® royalties. During the quarter, the Company also earned a $24.5 million regulatory milestone from Sanofi related to a U.S. approval of TZIELD®, with payment expected in the third quarter of 2026. Subsequent to June 30, 2026, MacroGenics received cash consideration of $119.6 million from Bora in connection with the completed sale of the Company’s GMP manufacturing operations. In addition, in August, the Company achieved a $10.0 million milestone pursuant to Gilead’s exercise of its option to obtain an exclusive license for a preclinical bispecific program under the companies’ 2022 collaboration agreement. The Company’s pro forma cash, cash equivalents and marketable securities as of June 30, 2026, including net proceeds from Bora, Sanofi and Gilead, totaled $327 million.
• Revenue: Total revenue was $32.8 million for the quarter ended June 30, 2026, compared with $6.9 million for the quarter ended June 30, 2025. The increase was primarily due to achievement of the $24.5 million regulatory milestone from Sanofi related to U.S. approval of TZIELD.
• R&D Expenses: Research and development expenses were $38.8 million for the quarter ended June 30, 2026, compared with $40.8 million for the quarter ended June 30, 2025. The decrease was primarily due to decreased costs related to lorigerlimab and discontinued programs, partially offset by increased trial costs related to MGC026 and MGC028.
• G&A Expenses: General and administrative expenses were $7.9 million for the quarter ended June 30, 2026, compared with $9.3 million for the quarter ended June 30, 2025. The decrease was primarily due to lower personnel-related costs, including stock-based compensation expense.
• Net Income (Loss): Net income was $19.5 million for the quarter ended June 30, 2026, compared with net loss of $36.3 million for the quarter ended June 30, 2025. Net income for the quarter ended June 30, 2026, reflects income from discontinued operations of $89.2 million related to the sale of the Company's GMP manufacturing operations to Bora, and a $52.8 million non-cash loss on the extinguishment of the ZYNYZ royalty monetization liability.
• Shares Outstanding: Shares of common stock outstanding as of June 30, 2026, were 63,645,711.
• Cash Runway Guidance: MacroGenics anticipates that its pro forma cash, cash equivalents and marketable securities of $327 million as of June 30, 2026, plus other projected future payments from partners, will support the Company’s cash runway through 2028.
