AbbVie to Present New Data at WCLC 2026 Showcasing Innovation Across Lung Cancer Pipeline

• Clinical data from AbbVie's ABBV-1480 (RC148) PD-1/VEGF bispecific antibody in the frontline non-small cell lung cancer (NSCLC) setting will be presented via an oral presentation
• Additionally, new data and updates from AbbVie's telisotuzumab adizutecan (Temab-A) and ABBV-706 programs across NSCLC and small cell lung cancer (SCLC) to be shared
• Research reflects AbbVie's strategy aimed at building a lung cancer pipeline spanning next-generation immunotherapies, targeted antibody-drug conjugates (ADCs) and the potential for novel combination approaches

AbbVie (NYSE: ABBV) today announced new data highlighting research programs across its lung cancer portfolio being presented at the 2026 World Conference on Lung Cancer (WCLC), including non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The presentations span clinical, translational and real-world data across next-generation immunotherapies and targeted antibody-drug conjugates (ADCs), designed to generate insights into treatment burden, patient experience and biomarker identification that may help inform future research.

"Our strategy in lung cancer is focused on building a complementary pipeline that brings together next-generation immunotherapies and targeted antibody-drug conjugates with the potential to address different aspects of tumor biology," said Daejin Abidoye, M.D., vice president and therapeutic area head of oncology, solid tumor and hematology at AbbVie. "Exploring the PD-1/VEGF approach represented by ABBV-1480 and the c-Met targeting by Temab-A are important elements of that strategy and may provide a foundation for potential novel combinations as we work to develop more tailored treatment approaches for people living with lung cancer."

Advancing Novel Therapies Across Various Modalities in NSCLC
Multiple presentations across AbbVie's NSCLC portfolio will showcase new studies and data analyses spanning multiple treatment modalities, highlighting first-line treatment approaches, patient experience and biomarker-informed research.

• ABBV-1480 (RC148): AbbVie, in partnership with RemeGen, will present Phase 1b data evaluating the investigational PD-1/VEGF bispecific antibody, ABBV-1480, in combination with platinum-based chemotherapy as a potential first-line treatment for advanced NSCLC. At the 10 mg/kg dose, identified as the recommended Phase 3 dose for further development in combination regimens in both squamous and non-squamous NSCLC, the primary endpoint of objective response rate (ORR) was 90.0% in squamous NSCLC (n=27/30) and 75.9% (n=22/29) in non-squamous NSCLC. The most common treatment-related adverse events (TRAEs) were a decrease in white blood cells, neutrophil, platelet counts and anemia. No grade ≥3 hemorrhages with the 10 mg combinations were observed. This overall manageable safety profile supports ongoing Phase 3 development for this novel investigational asset.¹ 
  
  
• Telisotuzumab adizutecan (Temab-A), an investigational c-Met-directed ADC with a topoisomerase 1 inhibitor (Top1i) payload: Building on encouraging preliminary activity² observed in heavily pretreated patients, AbbVie initiated a Phase 1b/2 M24-536 study (NCT06772623). The study is evaluating a platinum-free combination of Temab-A and a PD-1 inhibitor, as a potential first-line treatment for advanced non-squamous NSCLC. The study includes analyses of c-Met and PD-L1 expression to identify the patients most likely to benefit from treatment.³ Temab-A is also being studied in epidermal growth factor receptor (EGFR)-mutated NSCLC as monotherapy or in combination with osimertinib (NCT07155187).

Clinical Data Showcasing the Potential of ABBV-706 in SCLC
ABBV-706 is an investigational SEZ6-targeted ADC with a Top1i payload, being evaluated in SCLC. Presentations at WCLC include research that further characterizes the program and the potential role of SEZ6 in SCLC.

• As previously reported, ABBV-706 demonstrated an ORR of 82% in patients with relapsed/refractory SCLC post platinum-based chemotherapy (n=17).⁴ New safety analyses from 240 patients who received ABBV-706 monotherapy showed generally manageable hematologic and gastrointestinal toxicities, with the most common gastrointestinal events, including nausea (35.8%), vomiting (17.5%) and diarrhea (10.8%), being largely low grade and most requiring no dose adjustments.⁵ Grade ≥3 treatment-related pneumonitis or interstitial lung disease was reported in 1.7% of patients receiving ABBV-706 monotherapy.⁶ Hematologic toxicities, including anemia, neutropenia and thrombocytopenia, were among the most common TRAEs.⁵ Serious TRAEs occurred in 12.5% of patients. ABBV-706 is being evaluated as monotherapy in a Phase 3 study (NCT07365241) and in combination with atezolizumab in the Phase 2 study (NCT07155174), in SCLC.
  
  
• Real-world research demonstrated that SEZ6 is broadly expressed in 91% of SCLC patients overall and in more than 96% of patients with brain or liver metastases. These findings further support SEZ6 as a potential therapeutic target in SCLC and other SEZ6-expressing tumors. ⁷
