AstraZeneca to present overall survival data from four pivotal Phase III trials in Presidential Symposia at ESMO 2026 featuring Sone-Ve, IMFINZI® (durvalumab), TAGRISSO® (osimertinib) and savolitinib

AstraZeneca

CLARITY-Gastric01 data will demonstrate potential of Sone-Ve to establish new treatment for broad population of CLDN18.2-positive gastric cancer patients

SAFFRON results will highlight clinical benefit of adding savolitinib to backbone TAGRISSO in MET-driven 2nd-line EGFRm lung cancer

VOLGA and DeLLphi-305 data will showcase the transformative potential of combining IMFINZI with novel agents to set new standards of care in bladder and small cell lung cancer

WILMINGTON, Del., October 19, 2026--AstraZeneca advances its ambition to revolutionize cancer care with new data across its diverse, industry-leading portfolio and pipeline at the European Society for Medical Oncology (ESMO) Congress, October 23-27, 2026.

More than 100 abstracts will be presented, including data from five pivotal Phase III trials, four of which will be featured in Presidential Symposia. This breadth of data will demonstrate how AstraZeneca is redefining the way cancer is treated with innovative combinations, precision medicine and antibody drug conjugates (ADCs) across bladder, lung and gastric cancers. Highlights include:

  • CLARITY-Gastric01: Phase III trial of sonesitatug vedotin (Sone-Ve), a wholly owned Claudin-18.2 (CLDN18.2) ADC, in 2nd and later-line CLDN18.2-positive (≥25%) advanced gastric or gastroesophageal junction (GEJ) cancers versus investigator's choice of therapy. This is the first Phase III trial to show a statistically significant and clinically meaningful overall survival (OS) benefit with an anti-CLDN18.2 ADC in this setting. Approximately 60% of patients have CLDN18.2 expression ≥25% in this setting. (Presidential Symposium 2 Abstract #LBA7).

  • SAFFRON: Phase III trial of TAGRISSO® (osimertinib) plus savolitinib in patients with MET-driven, epidermal growth factor receptor-mutated (EGFRm) non-small cell lung cancer (NSCLC) who progressed on prior treatment versus platinum-based chemotherapy (Presidential Symposium 2 Abstract #LBA6).

  • DeLLphi-305: Amgen-led Phase III trial of IMFINZI® (durvalumab) plus tarlatamab-dlle as a 1st-line maintenance treatment for extensive-stage small cell lung cancer versus IMFINZI alone (Presidential Symposium 1 Abstract #LBA3).

  • VOLGA: Phase III trial of perioperative IMFINZI in combination with neoadjuvant enfortumab vedotin in patients with muscle-invasive bladder cancer who are ineligible for or have refused cisplatin-based chemotherapy, versus surgery with or without approved adjuvant treatment (Presidential Symposium 1 Abstract #LBA2).

  • SANOVO: Hutchmed-led Phase III trial of TAGRISSO plus savolitinib in treatment-naïve patients with MET-overexpressed, EGFRm locally advanced or metastatic NSCLC versus TAGRISSO alone in China (Proffered Paper Abstract #LBA69).

  • NeoCOAST-2: Association of ctDNA clearance with clinical outcomes in a global platform Phase II perioperative trial of IMFINZI combinations with DATROWAY® (datopotomab deruxtecan-dlnk), oleclumab and monalizumab in NSCLC (Rapid Oral Session Abstract #4244RO).

  • FONTANA: Phase I/IIa trial of torvutatug samrotecan (Torvu-Sam), a folate receptor α (FRα)-targeting ADC as monotherapy in patients with platinum-resistant recurrent ovarian cancer (Rapid Oral Session Abstract #1245RO).

  • AZD7003: Updated results from a Phase I trial of C-CAR031, a Glypican 3 (GPC3) CAR-T, in advanced hepatocellular carcinoma (Rapid Oral Session Abstract #1680RO).
