AstraZeneca advances its ambition to redefine cancer care with new data across its portfolio and pipeline at the American Society of Clinical Oncology (ASCO) Annual Meeting, May 31 to June 4, 2024. More than 100 abstracts will feature 25 approved and potential new medicines across the Company?s diverse oncology portfolio and pipeline, including two late-breaking plenary presentations, a special late-breaking abstract session presentation and 15 oral presentations. Highlights include: LAURA Phase III trial of TAGRISSO®(osimertinib) in unresectable, Stage III epidermal growth factor receptor-mutated (EGFRm) non-small cell lung cancer (NSCLC) after chemoradiotherapy (CRT) (Plenary LBA4).

ADRIATIC Phase III trial of IMFINZI®(durvalumab) in patients with limited-stage small cell lung cancer (LS-SCLC) who had not progressed following concurrent CRT (cCRT) (Plenary LBA5). DESTINY-Breast06 Phase III trial of ENHERTU®(fam-trastuzumab deruxtecan-nxki) in patients with metastatic hormone receptor (HR)-positive HER2-low and HER2-ultralow metastatic breast cancer following one or more lines of endocrine therapy (LBA1000). First-in-human, investigator-initiated trial of C-CAR031, a novel autologous armored Glypican 3 (GPC3) targeting chimeric antigen receptor T cell (CAR-T) therapy, in patients with liver cancer.

The CAR-T is based on AZD5851, a novel cell therapy designed by AstraZeneca (Rapid Oral Abstract 4019). Two late-breaking presentations from the externally sponsored I-SPY2.2 Phase II trial of neoadjuvant datopotamab deruxtecan (Dato-DXd), alone and in combination with IMFINZI, in patients with breast cancer (LBA501 and LBA509). In metastatic lung cancer, the Company will present data that underscore its commitment to extending the benefits of antibody drug conjugates (ADCs) to more patients.

A poster presentation will share updated safety and efficacy results, including PD-L1 expression, from the TROPION-Lung02 Phase Ib trial of datopotamab deruxtecan plus pembrolizumab with or without platinum chemotherapy as 1st-line treatment for patients with advanced NSCLC without actionable genomic alterations. These data build on previously presented results from the TROPION-Lung-1 Phase III trial demonstrating the potential of this novel ADC in advanced disease. Datopotamab deruxtecan in combination with immunotherapies is being further explored in multiple Phase III trials in this setting, including AVANZAR, TROPION-Lung07 and TROPION-Lung08.

Redefining the breast cancer treatment landscape with ADCs across subtypes and stages of disease A late-breaking presentation will showcase efficacy and safety outcomes from the DESTINY-Breast06 Phase III trial. In April, high-level results showed ENHERTU demonstrated a statistically significant and clinically meaningful improvement in PFS versus standard-of-care chemotherapy in patients with HR-positive, HER2-low metastatic breast cancer. A clinically meaningful PFS improvement was also seen in patients with HER2-ultralow expression.

Advancing the next wave of medicines and combination therapies to attack cancer from multiple angles A rapid oral presentation will spotlight safety and preliminary efficacy results from an investigator-initiated Trial of C-CAR031, a novel autologous armored Glypican 3 (GPC3) targeting chimeric antigen receptor T cell (CAR-T) therapy that is being investigated for hepatocellular carcinoma. The CAR-T is based on AZD5851, a novel cell therapy designed by AstraZeneca using their transforming growth factor-beta receptor II (TGFßRII) dominant negative armoring platform and is manufactured by AbelZeta Pharmaceuticals Inc. C-CAR031 is being developed in China under a co-development agreement between AbelZeta and AstraZeneca. AstraZeneca?s TGFßRII dominant negative armoring is designed to resist the immuno-suppressive tumor microenvironment and enhance the potential effectiveness of CAR-Ts in solid tumors.

A rapid abstract update will feature updated efficacy data from a Phase I trial of AZD0901, a potential first-in-class ADC targeting Claudin 18.2, which has shown promise as a therapeutic target in gastric cancer. First results were presented at the ASCO Plenary Series 2023.
