NextCure Announces First Patient Dosed in the Phase 1 Study of LNCB74 (B7-H4 ADC) as Therapeutic for Treating Multiple Cancers

BELTSVILLE, Md.– January 10 , 2025–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 announced the first patient has been dosed in its Phase 1 study of LNCB74, a B7-H4-targeting antibody-drug conjugate (ADC) as a therapeutic for treating multiple cancers.

“Dosing the first patient in the LNCB74 Phase 1 study is a significant milestone for NextCure as we continue to advance our B7-H4 ADC program,” said Udayan Guha, M.D., Ph.D., NextCure’s Senior Vice President, Clinical & Translational Development. “We look forward to establishing the safety, tolerability, and preliminary anti-tumor activity of LNCB74. We believe this novel ADC could potentially transform treatment options for multiple cancers.”

LNCB74 is being developed in partnership with LigaChem Biosciences as part of a collaboration agreement.
