NORTH CHICAGO, Ill., Oct. 18, 2026 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that new and updated data from its broad solid tumor portfolio will be presented at the 2026 European Society for Medical Oncology (ESMO) Congress, taking place October 23-27 in Madrid, Spain. Spanning multiple tumor types, therapeutic modalities and stages of development, the presentations represent AbbVie's most expansive ESMO program to date.

Collectively, the findings across Temab-A (telisotuzumab adizutecan), ABBV-706, ABBV-969, ABBV-1480 (RC148), alveltamig, Elahere^® (mirvetuximab soravtansine-gynx) and Emrelis™ (telisotuzumab vedotin-tllv) demonstrate how AbbVie is leveraging its deep expertise in cancer biology to advance differentiated approaches that address the complexity and heterogeneity of solid tumors and help meet the diverse needs of cancer patients worldwide.

"The data we are presenting at ESMO reflects the progress being made through AbbVie's disciplined, biology-driven approach to oncology innovation," said Daejin Abidoye, vice president, therapeutic area head of oncology, solid tumor and hematology, AbbVie. "Across multiple tumor types and stages of development, we are seeing encouraging evidence of longer-term clinical benefit, promising outcomes in biomarker-defined patient populations, and the potential of novel combinations and next-generation platforms. Together, these findings reinforce our strategy of translating scientific insights into differentiated treatment approaches with the potential to meaningfully improve outcomes for patients living with cancer."

Selected findings from AbbVie's investigational solid tumor portfolio include updated clinical, survival and translational biomarker data across multiple antibody-drug conjugates (ADCs) and bispecific antibody programs, supporting continued development across a range of solid tumors:

• Temab-A
  • Updated data continue to demonstrate encouraging clinical activity for Temab-A, an investigational, next-generation, c-Met-directed ADC with a novel topoisomerase 1 inhibitor (Top1i), across multiple solid tumor types.
  • In a Phase 1 study of patients with previously treated advanced colorectal cancer (CRC), pooled data from the safety lead-in and dose-optimization cohorts showed that Temab-A (2.4 mg/kg) in combination with bevacizumab demonstrated a 30% overall response rate (ORR) and encouraging overall survival (OS) outcomes after a median follow-up of 18.2 months. Median OS reached 14.7 months with the combination (n=30), compared with 10.2 months for standard of care (n=20), regardless of c-Met protein expression level. No new safety signals were observed.¹ This combination is being further evaluated in the ongoing global Phase 3 AndroMETa-CRC-560 study (NCT07525206).
  • In an updated analysis from the ongoing Phase 1 study of Temab-A in non-squamous non-small cell lung cancer (NSCLC), the ORR was 50% with a median OS of 13.8 months in unselected patients with epidermal growth factor receptor (EGFR) wild-type disease (n=48). Among patients with EGFR-mutant disease (n=41), ORR was observed at 63% with a median OS of 16.2 months. In patients with EGFR wild-type disease, at the c-Met 3+, ≥25% expression threshold, median OS was approximately 19.2 months. As a monotherapy, Temab-A is being further evaluated, compared to the standard of care, in the global Phase 3 AndroMETa-Lung-167 study for previously treated patients with EGFR wild-type, non-squamous NSCLC (NCT07821684). 
  • In a separate post-hoc pooled exploratory analysis of 19 patients with EGFR-mutant NSCLC and baseline brain metastases, Temab-A achieved a 37% intracranial ORR, with a median duration of intracranial response of 19.8 months. No new safety signals were observed.
  • AbbVie recently announced that Temab-A received two U.S. FDA Breakthrough Therapy Designations in CRC and NSCLC based, in part, on the data highlighted above. These designations further underscore the potential of Temab-A in addressing patient needs in these disease areas.
• ABBV-706: 
  • Updated Phase 1 findings reinforce the potential of ABBV-706, a SEZ6-directed ADC with a Top1i payload, in patients with relapsed/refractory (R/R) small cell lung cancer (SCLC), while new biomarker and translational findings further support SEZ6 as a promising therapeutic target.
  • At the selected Phase 3 dose of 1.8 mg/kg (n=41), in a heavily pre-treated population, ABBV-706 achieved a 56% ORR and 12.4-month median OS in 2L+ SCLC patients; in the 2L-only subset (n=17), ORR increased to 82% and a 14.4-month median OS was observed. Safety was comparable to previously reported data.
  • ABBV-706 is being further evaluated in an ongoing, randomized, open-label, multicenter Phase 3 trial versus standard of care in patients with R/R SCLC (NCT07365241).
• ABBV-969:
  • Biomarker findings from a Phase 1 dose escalation study (NCT06318273) of ABBV-969 demonstrated robust molecular responses in heavily pretreated (median 5 prior lines of therapy) metastatic castration-resistant prostate cancer (mCRPC) patients (n=49). By cycle 3, 90% of patients achieved a ≥50% reduction in circulating tumor DNA (ctDNA) and 78% experienced circulating tumor cell conversion from unfavorable to favorable levels (≥5 to <5 cells).
  • Among 27 patients with baseline PSMA PET assessments receiving ABBV-969 at doses ≥3 mg/kg, two were PSMA PET-negative per VISION criteria; both achieved a PSA50 response, including one patient with stable disease and one with a confirmed partial response.⁴ 
  • Together, these data further support the continued clinical development of ABBV-969, AbbVie's dual-targeting ADC approach to address tumor heterogeneity by simultaneously targeting two highly prevalent targets associated with mCRPC, prostate-specific membrane antigen (PSMA) and six-transmembrane epithelial antigen of prostate 1 (STEAP1), while delivering a Top1i payload.
• ABBV-1480 
  • New data continue to support the development potential of ABBV-1480, a PD-1 × VEGF bispecific antibody, in lung cancer and other solid tumors.
  • In a Phase 1 study of patients with first-line PD-L1-positive NSCLC, ABBV-1480 monotherapy (n=22) achieved a 61.9% ORR and a median progression-free survival (PFS) of 15.2 months.⁵ In previously treated NSCLC, ABBV-1480 combined with docetaxel at the 20 mg/kg dose (n=21) delivered a 66.7% ORR and 8.5-month median PFS.⁵ The most common grade ≥3 treatment-related adverse events for monotherapy were hypertension and proteinuria; for combination therapy, they were decreased neutrophil count, decreased white blood cell count and decreased lymphocyte count.⁵
  • ABBV-1480 continues to advance in clinical development, including the global Phase 3 AMUR-Lung-01 trial (NCT07756645) and a newly initiated combination study with Temab-A in NSCLC (NCT07874282).
