AstraZeneca advances its ambition to eliminate cancer as a cause of death and transform outcomes for people living with rare diseases with new data across its diverse, industry-leading portfolio and pipeline at the American Society of Clinical Oncology (ASCO) Annual Meeting, 29 May to 2 June 2026.

More than 85 abstracts will feature 10 approved and 13 potential new medicines from the Company, including 25 oral presentations. Highlights include:
 

• EMERALD-3: Phase III trial of Imfinzi (durvalumab) in combination with Imjudo (tremelimumab), with or without lenvatinib, and transarterial chemoembolisation (TACE) in patients with unresectable hepatocellular carcinoma (HCC) eligible for embolisation (Oral Abstract #LBA4000).
• CARES: Phase III clinical programme of anselamimab, a potential first-in-class anti-fibril therapy from Alexion, AstraZeneca Rare Disease, in newly diagnosed patients with light chain (AL) amyloidosis receiving standard of care for underlying plasma cell dyscrasia, including results from a prespecified subgroup analysis based on involved kappa (κ) or lambda (λ) free light chain (Oral Abstract #7501).
• SERENA-6: Final progression-free survival 2 (PFS2) results and circulating tumour DNA (ctDNA) clearance data linked to longer-term efficacy outcomes from the SERENA-6 Phase III trial of camizestrant in combination with widely approved cyclin-dependent kinase (CDK) 4/6 inhibitors in the 1st-line treatment of patients with hormone receptor (HR)-positive, HER2-negative advanced breast cancer whose tumours have an emergent ESR1 mutation (Oral Abstract #LBA1007).
• BLUESTAR: Updated safety and efficacy results from the BLUESTAR Ph I/IIa trial of the B7-H4-directed ADC puxitatug samrotecan (Puxi-Sam) in patients with relapsed/metastatic B7-H4-positive endometrial and ovarian cancer who progressed on prior standard-of-care therapy (Rapid Oral Abstract #5515). Puxi-Sam was recently granted Breakthrough Therapy Designation by the US Food and Drug Administration (FDA) in this setting.
• PRIMAVERA: Safety and preliminary efficacy from the first-in-human Phase I PRIMAVERA trial of the protein arginine methyltransferase 5 (PRMT5) inhibitor AZD3470 as monotherapy in relapsed/refractory classic Hodgkin lymphoma (Oral Abstract #7003).
• Phase I initial results for NT-175 T-cell receptor therapy in TP53 R175H-mutated unresectable, advanced and/or metastatic solid tumours including pancreatic adenocarcinoma (Oral Abstract #2506).
• TROPION-Breast02: Additional efficacy endpoints from the TROPION-Breast02 Phase III trial of Datroway (datopotamab deruxtecan) as 1st-line treatment for patients with locally recurrent inoperable or metastatic triple-negative breast cancer (TNBC) who are not candidates for PD-1/PD-L1 inhibitors (Oral Abstract #1002).
• DESTINY-Breast09: Exploratory analysis of treatment duration and clinical outcomes by complete response, partial response or stable/progressive disease in the DESTINY-Breast09 Phase III trial of Enhertu in combination with pertuzumab for the 1st-line treatment of patients with HER2-positive metastatic breast cancer (Rapid Oral Abstract #1021).
• POTOMAC: Five-year overall survival and patient-reported outcomes from the Phase III POTOMAC trial of Imfinzi plus Bacillus Calmette-Guérin (BCG) induction and maintenance therapy in patients with high-risk non-muscle-invasive bladder cancer (Rapid Oral Abstract #4624).

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "The data at ASCO for our innovative medicines and next-wave assets further our strategy to redefine patient outcomes by taking novel combinations into earlier stages of disease and advancing new modalities. New data for Enhertu, Datroway and camizestrant reinforce their transformational potential in breast cancer. We're also excited to share first clinical data for our T-cell receptor therapy, NT-175, and our PRMT5 inhibitor, AZD3470, as well as updated data for our most advanced in-house antibody drug conjugate, Puxi-Sam, which was recently granted Breakthrough Therapy Designation by the FDA. Collectively, these datasets underscore the strength and depth of our oncology pipeline."

Dave Fredrickson, Executive Vice President, Oncology Haematology Business Unit, AstraZeneca, said: "The EMERALD-3 data for Imfinzi and Imjudo in early liver cancer exemplify our successful strategy to move immunotherapy regimens into earlier stages of cancer where we can further improve outcomes for patients. With more than a dozen different indications approved across five cancer medicines in the last six months alone, we are reaching more patients with our growing portfolio, underscoring both the quality of our innovation and the strength of our business."

Gianluca Pirozzi, Head of Development, Regulatory and Safety, Alexion, said: "Results from the CARES Phase III clinical programme highlight the pioneering potential of anselamimab as a first-in-class, anti-fibril therapy for patients with kappa light chain amyloidosis. Its novel mechanism of action is designed to target and deplete amyloid deposits in affected organs, with potential to extend survival and reduce cardiovascular hospitalisations."

AstraZeneca is collaborating with Daiichi Sankyo to develop and commercialise Enhertu and Datroway.
