BELTSVILLE, Md., March 05, 2026 (GLOBE NEWSWIRE) -- NextCure, Inc. (NASDAQ:NXTC), a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class, and best-in-class therapies to treat cancer, today provided a business update and reported full year 2025 financial results.

"2026 is on track to be transformational for NextCure, as we set the stage to present clinical dose escalation data from the Phase 1 trial for SIM0505, in development for multiple cancers," said Michael Richman, President and CEO of NextCure. "Since acquiring the program in June of 2025, we have made rapid clinical and regulatory progress and soon expect to begin enrolling platinum resistant ovarian cancer patients in the Phase 1 dose optimization study.

Business Highlights and Near-Term Milestones

SIM0505 (CDH6 ADC): Phase 1 dose escalation data expected in Q2 2026

SIM0505 is a novel ADC directed to cadherin-6 (CDH6 ADC), overexpressed in several cancers including ovarian cancer, with limited expression in healthy tissues. SIM0505 features a proprietary topoisomerase 1 inhibitor (TOPOi) payload, designed for broad anti-tumor activity, fast systemic clearance and an improved potential therapeutic window.

• Data from the Phase 1 open-label dose escalation study is expected to be presented in the second quarter of 2026, including results from patients in the U.S. and China.
• The study (NCT06792552) is evaluating SIM0505 in patients with advanced solid tumors with a focus on gynecological cancers and an emphasis on platinum resistant ovarian cancer (PROC).
• Initiation of Phase 1 dose optimization study in ovarian cancer expected in the second quarter of 2026 with a continued focus on PROC. The Company anticipates doubling the number of trial sites in the second half of 2026, including the activation of sites in Canada and Europe, with continued study site additions in 2027.
  
  
  
  

LNCB74 (B7-H4 ADC): Ongoing enrollment in Phase 1 dose escalation

LNCB74 is a novel ADC directed to B7-H4, overexpressed in several cancers, with limited expression in healthy tissues. LNCB74 features a proprietary tumor-selective cleavable linker and a tubulin inhibitor monomethyl auristatin E (MMAE) payload.

• Higher dose cohort enrollment initiated in the ongoing open-label Phase 1 dose escalation study (NCT06774963), following the November 2025 protocol amendment announcement. The next dose cohort will prioritize patients with high B7-H4 expression in breast and gynecological cancers, as well as the inclusion of patients with adenoid cystic carcinoma type 1.
• NextCure continues to plan to provide a trial update in the second half of 2026.
  
  
  
  

Financial Results for the Full Year Ended December 31, 2025

• Cash, cash equivalents, and marketable securities as of December 31, 2025 were $41.8 million as compared to $68.6 million as of December 31, 2024. The decrease of $26.8 million was primarily due to cash used to fund operations of $49.6 million, including $13.5 million of upfront license fees and milestone payments to Simcere Zaiming Pharmaceutical Co., Ltd. for the rights to SIM0505, partially offset by proceeds of $22.3 million from equity sales including a $21.5 million private placement of common stock in November 2025. NextCure expects current financial resources to be sufficient to fund operating expenses and capital expenditures into the first half of 2027 through proof-of-concept for SIM0505.
• Research and development expenses were $44.9 million for the full year ended December 31, 2025, as compared to $41.5 million for the full year ended December 31, 2024. The increase of $3.4 million was due to $18.5 million of license fees and milestone payments for SIM0505 partially offset by lower costs related to deprioritized programs, lower preclinical development costs and lower personnel-related costs.
• General and administrative expenses were $12.7 million for the full year ended December 31, 2025, as compared to $15.7 million for the full year ended December 31, 2024. The decrease of $3.0 million was primarily related to lower personnel costs.
• Net loss was $55.8 million for the full year ended December 31, 2025, as compared to a net loss of $55.7 million for the full year ended December 31, 2024. Net loss for the year ended December 31, 2025 was driven by higher research and development costs and lower other income of $2.3 million, partially offset by lower general and administrative costs and lower restructuring charges.
