(NASDAQ:XNCR), a clinical-stage biopharmaceutical company developing engineered antibodies for the treatment of cancer and autoimmune diseases, today reported financial results for the fourth quarter and full year ended December 31, 2025. “Xencor’s lead oncology drug candidate is XmAb819, a novel first-in-class T-cell engager that could offer a much-needed new therapeutic modality for patients with advanced clear cell renal cell carcinoma (ccRCC). Excitement from the clinical community on our initial data from the dose-escalation study presented during ENA 2025 supports achieving our goal of presenting dose-expansion data during a medical meeting in the second half of 2026 and our plans to initiate a pivotal study during 2027,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. “Building on the early success in ccRCC, we recently opened additional dose expansion cohorts in other tumor types that have high ENPP3 expression: colorectal cancer, non-small cell lung cancer and papillary renal cell carcinoma.” “In 2026, we plan to present additional key clinical data and progress updates as we also advance XmAb541 and our ongoing B-cell depleting autoimmune programs, respectively. Our TL1A pipeline in inflammatory bowel disease continues to advance, as well. We are making great progress with enrollment in our Phase 2b XENITH-UC study of XmAb942 and are excited to begin the first-in-human study of XmAb412, our novel TL1A x IL23p19 bispecific antibody in the second half of 2026. We are proud of our execution across an evolved clinical pipeline and of the Xencor team’s focus on designing proteins to deliver novel medicines for patients.” Wholly Owned Pipeline Overview XmAb819 (ENPP3 x CD3), a first-in-class, tumor-targeted T-cell engaging XmAb® 2+1 bispecific antibody in development for patients with advanced clear cell renal cell carcinoma (ccRCC).
