WILMINGTON, Del. / Aug 16, 2023 / Business Wire / AstraZeneca advances its robust lung cancer portfolio and pipeline at the International Association for the Study of Lung Cancer (IASLC) 2023 World Conference on Lung Cancer (WCLC), September 9-12, 2023.
More than 40 abstracts will feature eight approved and potential new medicines from AstraZeneca, including nine oral presentations and a late-breaking plenary Presidential Symposium presentation of results from the FLAURA2 Phase III trial of TAGRISSO® (osimertinib) in combination with chemotherapy for patients with locally advanced or metastatic epidermal growth factor receptor-mutated (EGFRm) lung cancer.
Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: “Our data at WCLC support our ambition to have the right AstraZeneca medicine for more than half of all patients treated for lung cancer by 2030, and underscore the need to increase screening and early diagnosis to improve patient outcomes. The strong results from FLAURA2 will further establish TAGRISSO as the backbone therapy in EGFR-mutated non-small cell lung cancer, and the recent Breakthrough Therapy Designation in the US is a significant validation of the potential we see for this regimen.”
Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “Following last year’s accelerated approval of ENHERTU as the first HER2-directed therapy for patients with previously treated HER2-mutant metastatic lung cancer, new data at WCLC will reinforce its potential benefit to patients in need of targeted options. In addition, data for datopotamab deruxtecan will further support the potential to combine this agent with immune checkpoint inhibitors and the continued investigation of these combinations in first-line settings.”
Improving outcomes across early- and late-stage EGFRm lung cancer
A late-breaking plenary Presidential Symposium presentation will showcase progression-free survival (PFS) data from the FLAURA2 Phase III trial evaluating TAGRISSO in combination with chemotherapy for patients with locally advanced (Stage IIIB-IIIC) or metastatic (Stage IV) EGFRm non-small cell lung cancer (NSCLC). In May, high-level results showed the TAGRISSO combination demonstrated a statistically significant and clinically meaningful improvement in PFS compared to standard-of-care TAGRISSO monotherapy. In August, TAGRISSO plus chemotherapy was granted Breakthrough Therapy Designation in the US for advanced EGFRm NSCLC.
An oral presentation of results from a Phase IIIb trial will show the potential of savolitinib as a 1st-line treatment for advanced or metastatic NSCLC harboring MET exon 14 mutations. Savolitinib is approved for this indication in China.
In addition, an e-poster on a computational pathology analysis of MET expression in patients treated with a combination of savolitinib and TAGRISSO in the SAVANNAH Phase II trial will showcase the Company’s progress in developing transformational technology solutions to identify patients who are most likely to respond to treatment. Encouraging efficacy for the combination has been previously reported in the same study in patients with high levels of MET overexpression and/or amplification whose disease progressed on treatment with TAGRISSO.
Realizing the potential of antibody drug conjugates (ADCs) in advanced lung cancer
A late-breaking oral presentation of first results from the TROPION-Lung04 Phase Ib trial will highlight the safety and efficacy of datopotamab deruxtecan (Dato-DXd) plus IMFINZI® (durvalumab) with and without carboplatin in patients with previously treated or untreated, advanced or metastatic NSCLC without actionable genomic alterations. There are currently no TROP2-directed ADCs approved for the treatment of patients with lung cancer.
A mini-oral presentation of primary results from the DESTINY-Lung02 Phase II trial will share the first overall survival and PFS data for ENHERTU® (fam-trastuzumab deruxtecan-nxki) in patients with previously treated HER2-mutant metastatic NSCLC. ENHERTU is approved for this indication in a number of countries, including in the US, where it was granted accelerated approval based on interim results from the trial.
Two posters will feature AZD9592, an EGFR/cMET bispecific ADC designed to deliver targeted chemotherapy to cancer cells expressing both EGFR and cMET with a topoisomerase inhibitor 1 warhead using the Company’s proprietary linker technology. A trial-in-progress poster will describe the EGRET Phase I trial, a first-in-human study evaluating AZD9592 in patients with advanced solid tumors including in combination with TAGRISSO in metastatic EGFRm NSCLC. In addition, a poster on translational results for AZD9592 suggests it may provide clinical benefit in areas of unmet need, including in patients with NSCLC previously treated with chemotherapy or targeted agents. This is the Company’s first bispecific ADC to enter the clinic.
Reinforcing IMFINZI benefits alone and in novel combinations across lung cancer settings
Two late-breaking oral presentations will share new data from the AEGEAN Phase III trial of IMFINZI in combination with neoadjuvant chemotherapy before surgery and as adjuvant monotherapy after surgery in patients with resectable NSCLC, including key surgical outcomes and exploratory analyses of clinical outcomes in a subset of patients with EGFRm disease. Previously presented primary results from AEGEAN demonstrated statistically significant and clinically meaningful improvement in event-free survival and pathologic complete response with this IMFINZI-based regimen versus neoadjuvant chemotherapy alone followed by surgery.
Another oral presentation of data from a planned subset analysis of the PACIFIC-R observational study of IMFINZI in a real-world population of patients with EGFRm disease will explore the long-term clinical outcomes of IMFINZI in patients with unresectable, Stage III NSCLC.
Data will also be shared from new exploratory subgroup analyses of the POSEIDON Phase III trial describing patients deriving long-term benefit from the combination of IMFINZI, IMJUDO® (tremelimumab-actl) and chemotherapy in the metastatic NSCLC setting.
Advancing our commitment to increase lung cancer screening and early diagnosis
An oral presentation will describe a framework to support government implementation of high-quality and impactful lung cancer screening programs. Screening is essential to early detection and reducing lung cancer mortality. Published in March 2023, the framework was developed by the Lung Cancer Policy Network, an initiative of the Lung Ambition Alliance aimed at elevating lung cancer as a policy priority worldwide. AstraZeneca is a founding member of the Lung Ambition Alliance, a global coalition working to accelerate innovation and deliver meaningful improvements for people with lung cancer, including and beyond treatment.
Collaboration in the scientific community is critical to improving outcomes for patients. AstraZeneca is collaborating with Daiichi Sankyo to develop and commercialize ENHERTU and datopotamab deruxtecan, and with HUTCHMED to develop and commercialize savolitinib.

Warnings and Precautions
Interstitial Lung Disease / Pneumonitis
Severe, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ENHERTU. A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Advise patients to immediately report cough, dyspnea, fever, and/or any new or worsening respiratory symptoms. Monitor patients for signs and symptoms of ILD. Promptly investigate evidence of ILD. Evaluate patients with suspected ILD by radiographic imaging. Consider consultation with a pulmonologist. For asymptomatic ILD/pneumonitis (Grade 1), interrupt ENHERTU until resolved to Grade 0, then if resolved in ≤28 days from date of onset, maintain dose. If resolved in >28 days from date of onset, reduce dose one level. Consider corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥0.5 mg/kg/day prednisolone or equivalent). For symptomatic ILD/pneumonitis (Grade 2 or greater), permanently discontinue ENHERTU. Promptly initiate systemic corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥1 mg/kg/day prednisolone or equivalent) and continue for at least 14 days followed by gradual taper for at least 4 weeks.
Metastatic Breast Cancer and HER2-Mutant NSCLC (5.4 mg/kg)
In patients with metastatic breast cancer and HER2-mutant NSCLC treated with ENHERTU 5.4 mg/kg, ILD occurred in 12% of patients. Fatal outcomes due to ILD and/or pneumonitis occurred in 1.0% of patients treated with ENHERTU. Median time to first onset was 5 months (range: 0.9 to 23).
Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)
In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, ILD occurred in 10% of patients. Median time to first onset was 2.8 months (range: 1.2 to 21).
Neutropenia
Severe neutropenia, including febrile neutropenia, can occur in patients treated with ENHERTU. Monitor complete blood counts prior to initiation of ENHERTU and prior to each dose, and as clinically indicated. For Grade 3 neutropenia (Absolute Neutrophil Count [ANC] <1.0 to 0.5 x 109/L), interrupt ENHERTU until resolved to Grade 2 or less, then maintain dose. For Grade 4 neutropenia (ANC <0.5 x 109/L), interrupt ENHERTU until resolved to Grade 2 or less, then reduce dose by one level. For febrile neutropenia (ANC <1.0 x 109/L and temperature >38.3º C or a sustained temperature of ≥38º C for more than 1 hour), interrupt ENHERTU until resolved, then reduce dose by one level.
Metastatic Breast Cancer and HER2-Mutant NSCLC (5.4 mg/kg)
In patients with metastatic breast cancer and HER2-mutant NSCLC treated with ENHERTU 5.4 mg/kg, a decrease in neutrophil count was reported in 65% of patients. Sixteen percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 22 days (range: 2 to 664). Febrile neutropenia was reported in 1.1% of patients.
Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)
In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, a decrease in neutrophil count was reported in 72% of patients. Fifty-one percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 16 days (range: 4 to 187). Febrile neutropenia was reported in 4.8% of patients.
Left Ventricular Dysfunction
Patients treated with ENHERTU may be at increased risk of developing left ventricular dysfunction. Left ventricular ejection fraction (LVEF) decrease has been observed with anti-HER2 therapies, including ENHERTU. Assess LVEF prior to initiation of ENHERTU and at regular intervals during treatment as clinically indicated. Manage LVEF decrease through treatment interruption. When LVEF is >45% and absolute decrease from baseline is 10-20%, continue treatment with ENHERTU. When LVEF is 40-45% and absolute decrease from baseline is <10%, continue treatment with ENHERTU and repeat LVEF assessment within 3 weeks. When LVEF is 40-45% and absolute decrease from baseline is 10-20%, interrupt ENHERTU and repeat LVEF assessment within 3 weeks. If LVEF has not recovered to within 10% from baseline, permanently discontinue ENHERTU. If LVEF recovers to within 10% from baseline, resume treatment with ENHERTU at the same dose. When LVEF is <40% or absolute decrease from baseline is >20%, interrupt ENHERTU and repeat LVEF assessment within 3 weeks. If LVEF of <40% or absolute decrease from baseline of >20% is confirmed, permanently discontinue ENHERTU. Permanently discontinue ENHERTU in patients with symptomatic congestive heart failure. Treatment with ENHERTU has not been studied in patients with a history of clinically significant cardiac disease or LVEF <50% prior to initiation of treatment.
Metastatic Breast Cancer and HER2-Mutant NSCLC (5.4 mg/kg)
In patients with metastatic breast cancer and HER2-mutant NSCLC treated with ENHERTU 5.4 mg/kg, LVEF decrease was reported in 3.6% of patients, of which 0.4% were Grade 3.
Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)
In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, no clinical adverse events of heart failure were reported; however, on echocardiography, 8% were found to have asymptomatic Grade 2 decrease in LVEF.
Embryo-Fetal Toxicity
ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. Verify the pregnancy status of females of reproductive potential prior to the initiation of ENHERTU. Advise females of reproductive potential to use effective contraception during treatment and for 7 months after the last dose of ENHERTU. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for 4 months after the last dose of ENHERTU.
Additional Dose Modifications
Thrombocytopenia
For Grade 3 thrombocytopenia (platelets <50 to 25 x 109/L) interrupt ENHERTU until resolved to Grade 1 or less, then maintain dose. For Grade 4 thrombocytopenia (platelets <25 x 109/L) interrupt ENHERTU until resolved to Grade 1 or less, then reduce dose by one level.

IMPORTANT SAFETY INFORMATION FOR IMFINZI® and IMJUDO®
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.
Immune-Mediated Colitis
IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal.
IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies.
Immune-Mediated Hepatitis
IMFINZI and IMJUDO can cause immune-mediated hepatitis, which may be fatal.
Immune-Mediated Endocrinopathies
Immune-Mediated Nephritis with Renal Dysfunction
IMFINZI and IMJUDO can cause immune-mediated nephritis.
Immune-Mediated Dermatology Reactions
IMFINZI and IMJUDO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), have occurred with PD-1/L-1 and CTLA-4 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes.
Immune-Mediated Pancreatitis
IMFINZI in combination with IMJUDO can cause immune-mediated pancreatitis. Immune-mediated pancreatitis occurred in 2.3% (9/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions.
Other Immune-Mediated Adverse Reactions
The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in patients who received IMFINZI and IMJUDO or were reported with the use of other immune-checkpoint inhibitors.
Infusion-Related Reactions
IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.
Complications of Allogeneic HSCT after IMFINZI
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT.

Embryo-Fetal Toxicity
Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO.
Lactation
There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.
