WILMINGTON, Del.--(BUSINESS WIRE)--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).

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "AstraZeneca’s portfolio of scientific data at ESMO is our strongest to date, showcasing transformative combinations including emerging modalities. Findings from VOLGA, DeLLphi-305 and SAFFRON demonstrate the potential of combination regimens with complementary mechanisms to improve on today’s standards of care, extend treatment benefit and meaningfully improve survival outcomes for more patients. These data, alongside practice-changing results for our first wholly owned ADC Sone-Ve from CLARITY-Gastric01 underscore how AstraZeneca is transforming cancer care."

Dave Fredrickson, Executive Vice President, Oncology Haematology Business Unit, AstraZeneca, said: “At ESMO, we are presenting pivotal data that demonstrate how we are advancing new standards of care by adding novel medicines to AstraZeneca’s proven backbone therapies. Results from VOLGA, DeLLphi-305 and SAFFRON highlight the potential of innovative IMFINZI- and TAGRISSO-based regimens to improve outcomes for patients across bladder and lung cancers, reinforcing our commitment to continually raising the bar for patients with cancer across the treatment landscape."

IMPORTANT SAFETY INFORMATION for TAGRISSO^® (osimertinib)

• There are no contraindications for TAGRISSO

• TAGRISSO can cause severe and fatal interstitial lung disease (ILD)/pneumonitis. ILD/pneumonitis occurred in 4% of the 1813 patients treated with TAGRISSO monotherapy who had not received recent definitive chemoradiation therapy; 0.4% of cases were fatal
  • ILD/Pneumonitis with TAGRISSO in combination with Pemetrexed and Platinum-based Chemotherapy: In the FLAURA2 study, ILD/pneumonitis occurred in 3.3% of the 276 patients who received TAGRISSO in combination with pemetrexed and platinum-based chemotherapy; 0.4% of cases were fatal
  • ILD/Pneumonitis Following Definitive Platinum-based Chemoradiation Therapy (CRT): In the LAURA study, following definitive platinum-based CRT, ILD/pneumonitis including radiation pneumonitis, occurred in 80 of the 143 patients (56%) who received TAGRISSO monotherapy and 28 of the 73 patients (38%) who received placebo. There was one fatal case (0.7%), 3.5% Grade 3, 34% Grade 2, and 18% Grade 1 adverse reactions of ILD/pneumonitis in TAGRISSO-treated patients. For TAGRISSO-treated patients, ILD/pneumonitis led to permanent discontinuation of TAGRISSO in 7% of patients and dosage interruptions of TAGRISSO in 35% of patients. Among the 46 patients who were rechallenged with TAGRISSO, 11% had recurrence of ILD/pneumonitis. In the 80 TAGRISSO-treated patients, ILD/pneumonitis resolved in 40%, resolved with sequelae in 1.3%, were resolving in 16%, did not resolve in 41%, and resulted in death in 1.3%

For patients receiving TAGRISSO who have not received recent definitive platinum-based CRT, withhold TAGRISSO and promptly investigate for ILD in patients who present with worsening of respiratory symptoms which may be indicative of ILD (eg, dyspnea, cough, and fever). Permanently discontinue TAGRISSO if ILD/pneumonitis is confirmed. For patients who have received recent definitive platinum-based CRT with Grade 1 ILD/pneumonitis, continue TAGRISSO or interrupt and restart, as appropriate. Permanently discontinue TAGRISSO in patients diagnosed with Grade ≥2 ILD/pneumonitis

• TAGRISSO can cause heart rate-corrected QT (QTc) interval prolongation. Of the 1813 TAGRISSO monotherapy-treated patients in clinical trials, 1.1% were found to have a QTc >500 msec, and 4.3% of patients had an increase from baseline QTc >60 msec. Of the 276 patients treated with TAGRISSO in combination with pemetrexed and platinum-based chemotherapy in the FLAURA2 study, 1.8% were found to have a QTc >500 msec, and 10.5% of patients had an increase from baseline QTc >60 msec. No QTc-related arrhythmias were reported. Clinical trials of TAGRISSO did not enroll patients with baseline QTc of >470 msec. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life-threatening arrhythmia

• TAGRISSO can cause cardiomyopathy, including cardiac failure, chronic cardiac failure, congestive heart failure, pulmonary edema or decreased ejection fraction. Cardiomyopathy occurred in 3.8% of the 1813 TAGRISSO-treated patients; 0.1% of cardiomyopathy cases were fatal. In the FLAURA2 study, cardiomyopathy occurred in 9% of the 276 patients who received TAGRISSO in combination with pemetrexed and platinum-based chemotherapy; 1.1% of cardiomyopathy cases were fatal. A decline in left ventricular ejection fraction (LVEF) ≥10% from baseline and to <50% LVEF occurred in 4.2% of 1557 patients who had baseline and at least one follow-up LVEF assessment. In the ADAURA study, 1.5% (5/325) of TAGRISSO-treated patients experienced LVEF decreases ≥10% from baseline and a drop to <50%. In the LAURA study, following platinum‑based CRT, 3% (4/135) of TAGRISSO-treated patients and no placebo-treated patients experienced LVEF decreases ≥10% and a drop to <50%. In the FLAURA2 study, 8% (21/262) of patients treated with TAGRISSO in combination with pemetrexed and platinum-based chemotherapy, who had baseline and at least one follow-up LVEF assessment, experienced LVEF decreases ≥10% and a drop to <50%. For patients receiving TAGRISSO monotherapy, conduct cardiac monitoring in patients with cardiac risk factors, including assessment of LVEF at baseline and during treatment. For patients receiving TAGRISSO in combination with pemetrexed and platinum-based chemotherapy, conduct cardiac monitoring in all patients, including assessment of LVEF at baseline and during treatment. Assess LVEF in patients who develop relevant cardiac signs or symptoms during treatment. For symptomatic congestive heart failure, permanently discontinue TAGRISSO

• Keratitis was reported in 0.6% of 1813 patients treated with TAGRISSO monotherapy in clinical trials. Promptly refer patients with signs and symptoms suggestive of keratitis (such as eye inflammation, lacrimation, light sensitivity, blurred vision, eye pain and/or red eye) to an ophthalmologist

• Postmarketing cases consistent with erythema multiforme major (EMM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported in patients receiving TAGRISSO. Withhold TAGRISSO if EMM, SJS, or TEN is suspected and permanently discontinue if confirmed

• Postmarketing cases of cutaneous vasculitis including leukocytoclastic vasculitis, urticarial vasculitis, and IgA vasculitis have been reported in patients receiving TAGRISSO. Withhold TAGRISSO if cutaneous vasculitis is suspected, evaluate for systemic involvement, and consider dermatology consultation. If no other etiology can be identified, consider permanent discontinuation of TAGRISSO based on severity

• Aplastic anemia has been reported in TAGRISSO-treated patients in clinical trials (0.06% of 1813) and postmarketing. Some cases had a fatal outcome. Inform patients of the signs and symptoms of aplastic anemia including but not limited to, new or persistent fevers, bruising, bleeding, and pallor. If aplastic anemia is suspected, withhold TAGRISSO and obtain a hematology consultation. If aplastic anemia is confirmed, permanently discontinue TAGRISSO. Perform complete blood count with differential before starting TAGRISSO, periodically throughout treatment, and more frequently if indicated

• Myalgia occurred in 4.8% of patients in the pooled safety population who received TAGRISSO as a monotherapy (n=1813), of these, 0.1% were grade 3. Myalgia with concurrent increased creatinine phosphokinase (CPK) elevation occurred in 0.1% of patients. The median time to onset of myalgia for these patients with CPK elevation was 648 days (range: 141 days to 1155 days). Grade 1 myositis occurred in 0.2% of patients who received TAGRISSO. Rhabdomyolysis has been reported in the post-marketing setting. Advise patients to report unexplained muscle pain or tenderness. Monitor CPK levels periodically during treatment with TAGRISSO and as clinically indicated in patients reporting unexplained muscle pain or tenderness. Withhold, then resume at the same or reduced dose

• Verify pregnancy status of females of reproductive potential prior to initiating TAGRISSO. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TAGRISSO and for 6 weeks after the last dose. Advise males with female partners of reproductive potential to use effective contraception for 4 months after the last dose

• Because of the potential for serious adverse reactions in breastfed infants from TAGRISSO, women should not breastfeed during treatment with TAGRISSO and for 2 weeks after the last dose

• Most common (≥20%) adverse reactions, including laboratory abnormalities, were:
  • TAGRISSO monotherapy: leukopenia, lymphopenia, thrombocytopenia, anemia, diarrhea, rash, musculoskeletal pain, neutropenia, nail toxicity, dry skin, stomatitis, and fatigue
  • TAGRISSO monotherapy following platinum-based chemoradiation therapy: lymphopenia, leukopenia, ILD/pneumonitis, thrombocytopenia, neutropenia, rash, diarrhea, nail toxicity, musculoskeletal pain, cough and COVID-19
  • TAGRISSO in combination with pemetrexed and platinum-based chemotherapy: leukopenia, thrombocytopenia, neutropenia, lymphopenia, rash, diarrhea, stomatitis, nail toxicity, dry skin, and increased blood creatinine

IMPORTANT SAFETY INFORMATION FOR IMFINZI^® (durvalumab) AND IMJUDO^® (tremelimumab-actl)

There are no contraindications for IMFINZI^® (durvalumab) or IMJUDO^® (tremelimumab-actl).

Severe and Fatal Immune-Mediated Adverse Reactions

Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis

IMFINZI and IMJUDO can cause immune-mediated pneumonitis, which may be fatal. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

• IMFINZI as a Single Agent
  • In patients who did not receive recent prior radiation, the incidence of immune-mediated pneumonitis was 2.4% (34/1414), including fatal (<0.1%), and Grade 3-4 (0.4%) adverse reactions.
  • In patients who received recent prior radiation, the incidence of pneumonitis (including radiation pneumonitis) in patients with unresectable Stage III NSCLC following definitive chemoradiation within 42 days prior to initiation of IMFINZI in PACIFIC was 18.3% (87/475) in patients receiving IMFINZI and 12.8% (30/234) in patients receiving placebo. Of the patients who received IMFINZI (475), 1.1% were fatal and 2.7% were Grade 3 adverse reactions.
  • The incidence of pneumonitis (including radiation pneumonitis) in patients with LS-SCLC following chemoradiation within 42 days prior to initiation of IMFINZI in ADRIATIC was 14% (37/262) in patients receiving IMFINZI and 6% (16/265) in patients receiving placebo. Of the patients who received IMFINZI (262), 0.4% had a fatal adverse reaction and 2.7% had Grade 3 adverse reactions.
  • The frequency and severity of immune-mediated pneumonitis in patients who did not receive definitive chemoradiation prior to IMFINZI were similar in patients who received IMFINZI as a single agent or with ES-SCLC or BTC when given in combination with chemotherapy.
