AbbVie to Present New Data at ESMO 2025 Reinforcing Leadership in Advancing Targeted Therapies for Solid Tumors

• New data from telisotuzumab adizutecan (Temab-A) and ABBV-706 across pancreatic, colorectal, and solid tumors, highlight progress in AbbVie's growing ADC portfolio designed to target difficult-to-treat cancers.

NORTH CHICAGO, Ill., Oct. 13, 2025 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced it will unveil new data from its robust antibody-drug conjugate (ADC) platform at the 2025 European Society for Medical Oncology (ESMO) Congress, taking place October 17-21, in Berlin, Germany. Data from investigational and approved ADCs across AbbVie's portfolio such as telisotuzumab adizutecan (Temab-A),^1-3 ABBV-706,^4,5 and Emrelis™ (telisotuzumab vedotin),⁶ in patients with difficult-to-treat tumor types where there is urgent need for additional treatment options,^7-15 will be featured in multiple presentations.

"Despite recent progress in the treatment of advanced solid tumors, patients still face limited options and pressing unmet needs," said Daejin Abidoye, M.D., vice president, therapeutic area head, oncology, solid tumor and hematology, AbbVie. "The compelling data we are sharing at ESMO showcases how we are advancing targeted therapies across a range of solid tumors and highlights the potential of our portfolio."

Key highlights
AbbVie will present three oral presentations for Temab-A, a next-generation, investigational c-Met directed ADC with a novel topoisomerase 1 inhibitor (Top1i) payload. Phase 1 results with Temab-A both as a monotherapy and in combination across advanced, solid tumors will be presented:

• Combination with bevacizumab (Bev) in Colorectal Cancer (CRC): In biomarker unselected patients with advanced CRC who have received three or more prior lines of therapy (NCT05029882), treatment with 2.4 mg/kg dose of Temab-A plus Bev (n=30) achieved an objective response rate (ORR) of 26.7% compared to an ORR of 0% with trifluridine/tipiracil with Bev (the current standard of care (SOC), n = 20).¹ Grade ≥3 treatment emergent adverse events (TEAEs) occurred in 67% and 65% of patients, respectively.¹
• Monotherapy in MET-Amplified Solid Tumors: Among 100 patients with advanced MET-amplified solid tumors, including non-small cell lung cancer (NSCLC) (n=29), CRC (n=22), gastroesophageal adenocarcinoma (GEA) (n=14), and 16 other tumor types (n=35) who had progressed after SOC treatment (NCT05029882), Temab-A monotherapy achieved an ORR of 46% across all dose levels and tumor types with higher responses observed in patients with NSCLC (69%) and GEA (71%).² The most common grade ≥3 TEAEs were anemia (40%) and neutropenia (34%).²
• Monotherapy in Pancreatic Ductal Adenocarcinoma (PDAC): Among 42 biomarker unselected patients with advanced/metastatic PDAC who experienced disease progression while receiving or after completing their first-line (1L) therapy (NCT06084481), Temab-A demonstrated an ORR of 24% overall and 40% in patients who received first-line gemcitabine-nab-paclitaxel treatment.³ Grade ≥3 TEAEs occurring in ≥10% of all patients were anemia (38%) and neutropenia (21%).³

"Temab-A continues to show meaningful clinical activity across an expanding range of solid tumors and patient populations, including patients with MET-amplification and increased c-Met expression as we have seen in previously presented data," said Vivek Subbiah, M.D., Chief, Early-Phase Drug Development, Sarah Cannon Research Institute and Temab-A investigator. "These data reinforce Temab-A's potential in multiple solid tumors and thereby warrant its further clinical investigation."

AbbVie will also present new analysis from a Phase 1 study of ABBV-706, a SEZ6-directed ADC with a Top1i payload, in relapsed/refractory small cell lung cancer (R/R SCLC) (NCT05599984).

• A post hoc analysis on data from R/R SCLC patients enrolled in the study, whose tumors had progressed after two lines of therapy (n=80), was done to compare the anti-cancer effect of ABBV-706 monotherapy vs. platinum-based SOC. All patients in this group had received the platinum-based SOC treatment as first-line therapy (1L SOC). Progression-free survival (PFS) during 1L SOC and PFS with ABBV-706 monotherapy as a subsequent line of treatment were analyzed in the same patients by paired Kaplan-Meier analysis. The findings suggest that ABBV-706 may have the potential to replace the platinum-based SOC as a first-line treatment in SCLC.⁴
• In the same trial, ABBV-706 treatment also resulted in rapid clearance of circulating tumor DNA (ctDNA) and circulating tumor cells (CTC). Patients with 100% ctDNA clearance had significantly higher PFS and overall survival (OS) vs. patients without ctDNA clearance.⁵ These data highlight the potential of ctDNA as an early response marker in SCLC.⁵

A Phase 2 study assessing ABBV-706 in combination with atezolizumab as replacement of platinum-based chemotherapy is currently ongoing (NCT07155174) in 1L SCLC.

Telisotuzumab adizutecan (Temab-A) and ABBV-706 are investigational medicines and are not approved by any health authorities worldwide. The safety and efficacy of these investigational medicines are under evaluation as part of ongoing clinical studies.

Elahere™ (mirvetuximab soravtansine) and Emrelis™ (telisotuzumab vedotin) are approved medicines being investigated for additional uses. Safety and efficacy have not been established for these unapproved additional uses.
