AbbVie Features New Data Across Difficult-to-Treat Solid Tumors and Blood Cancers at ASCO 2025, Highlighting Breadth and Depth of its Oncology Portfolio

-    Key oral presentations highlight new data from AbbVie's novel investigational antibody-drug conjugates (ADCs) including telisotuzumab adizutecan (ABBV-400, Temab-A) in advanced non-small cell lung cancer (NSCLC), ABBV-706 in high-grade neuroendocrine neoplasms (NENs) and pivekimab sunirine (PVEK) in blastic plasmacytoid dendritic cell neoplasm (BPDCN).

NORTH CHICAGO, Ill., May 27, 2025 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that key data from its broad oncology portfolio will be showcased across multiple oral presentations and posters at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting (May 30 - June 3, 2025). These new data highlight significant progress in AbbVie's robust oncology pipeline, across a range of difficult-to-treat solid tumors and blood cancers.

"The data we're presenting at this year's ASCO reflect the breadth and depth of our oncology pipeline and our unwavering commitment to research that could transform outcomes for patients facing cancer," said Roopal Thakkar, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "These presentations underscore our leadership in driving scientific innovation to address some of the most pressing unmet needs in oncology today by leveraging our innovative platforms such as ADCs."

An oral presentation on investigational telisotuzumab adizutecan (ABBV-400, Temab-A), a next-generation, c-Met directed antibody-drug conjugate (ADC) with a novel topoisomerase 1 inhibitor (Top1i) payload, will showcase:

• Preliminary safety and efficacy results in 41 patients with pre-treated, advanced epidermal growth factor receptor (EGFR)-mutated non-squamous non-small cell lung cancer (NSCLC) from the dose expansion part of a Phase 1 study (NCT05029882).¹ Patients received a median of 3 prior lines of therapies and 93% of patients had prior anti-EGFR treatment. The objective response rate (ORR) was 63%.¹ High ORR was observed regardless of c-Met protein expression levels.¹ At the time of data cut-off, 54% of responders experienced a ≥6 months duration of response (DoR).¹ The most common any-grade TEAEs in ≥30% of patients were anemia (63%), nausea (61%), vomiting (37%), decreased appetite (34%), and neutropenia (34%).¹ Additional data with 4 months follow-up will be presented at ASCO.
    
  Temab-A is also being evaluated in multiple ongoing clinical trials including a Phase 1/2 Study (NCT06772623) in first-line NSCLC without actionable genomic alterations in combination with budigalimab (AbbVie's investigational programmed cell death 1 inhibitor), a Phase 2 study (NCT06107413) in second-line metastatic colorectal cancer (CRC) in combination with fluorouracil, folinic acid and bevacizumab, and a Phase 3 study (NCT06614192) as monotherapy in patients with c-Met overexpressing refractory metastatic CRC.

"The anti-tumor activity of Temab-A in patients with pre-treated, advanced EGFR-mutated non-squamous NSCLC is encouraging and supports further exploration of this novel ADC in this setting," said Ross Camidge, M.D., Ph.D, University of Colorado Cancer Center, United States and principal investigator of the trial. "Temab-A appears to have a manageable safety profile and continues to show promising clinical activity in advanced NSCLC, which is associated with poor prognosis."

Additional oral presentations will highlight new safety and efficacy data for ABBV-706, a SEZ6-directed ADC with a Top1i payload, and pivekimab sunirine (PVEK), a novel ADC designed to target CD123:

• In a Phase 1 open-label study of ABBV-706 monotherapy, 64 patients with high-grade neuroendocrine neoplasms (NENs), a diverse group of rare and aggressive solid tumors, received ABBV-706 monotherapy IV at 1.3–3.5 mg/kg once every 3 weeks.^2,3 The entire cohort had an ORR of 31.3%, and a median DoR of 5.6 months.² The most common grade ≥3 TEAEs (cumulative across all dose levels), were anemia (45%), neutropenia (33%), and thrombocytopenia (21%).² Additional data will be presented at ASCO.
    
  This ongoing study (NCT05599984) is evaluating ABBV-706 as monotherapy, or in combination with budigalimab, carboplatin, or cisplatin, in patients with advanced solid tumors expressing SEZ6, including small-cell lung cancer, NENs and high-grade Central Nervous System tumors.
  
  
• Results from the open-label, multicenter Phase 1b/2 CADENZA trial (NCT03386513) of PVEK monotherapy in patients with previously untreated or relapsed/refractory (R/R) blastic plasmacytoid dendritic cell neoplasm (BPDCN), a highly aggressive and rare type of blood cancer, demonstrated clinical benefit.^4,5 The results show that among 33 untreated patients, the primary endpoint of composite complete response (CCR) rate, defined as CR + clinical CR (CR with minimal skin abnormality), was 70% (95% CI, 51.3-84.4) with a median duration of CCR of 9.8 months. ORR was 85%.⁴ In the 51 patients with R/R BPDCN, the CCR rate was 14% with a median duration of CCR of 9.2 months. ORR was 35%.⁴
    
  Among all the 84 patients enrolled, the most common grade ≥3 TEAEs were peripheral edema (12%).⁴ TEAEs led to discontinuation in 9% and 7% of patients with first-line and R/R BPDCN, respectively. ⁴ Additional data will be presented at ASCO.
    
  PVEK is also being evaluated in a Phase 1/2 study (NCT04086264) in R/R and newly diagnosed acute myeloid leukemia.

"Over the past few years, we've significantly expanded our ADC portfolio to investigate a broad range of solid tumors and blood cancers, reflecting our deep commitment to transforming cancer care through targeted therapies and biomarker driven approaches," said Daejin Abidoye, M.D., vice president, therapeutic area head of solid tumors, AbbVie. "These results highlight the potential of our investigational medicines to offer a meaningful clinical benefit in multiple difficult-to-treat cancers, where current treatment options are limited."
