AstraZeneca Data at WCLC Advance Ambition to Have an AstraZeneca Medicine for More Than Half of All Patients Treated for Lung Cancer by 2030

• FLAURA2 data reinforce TAGRISSO^® as backbone therapy for EGFR-mutated advanced lung cancer in combination with chemotherapy; granted Breakthrough Therapy Designation in the US
• Further results for ENHERTU^®, IMFINZI^® and datopotamab deruxtecan showcase strength of diverse ADC and IO portfolios to address unmet needs

WILMINGTON, Del.--(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.

Use in Specific Populations

• Pregnancy: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. There are clinical considerations if ENHERTU is used in pregnant women, or if a patient becomes pregnant within 7 months after the last dose of ENHERTU.
• Lactation: There are no data regarding the presence of ENHERTU in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ENHERTU and for 7 months after the last dose.
• Females and Males of Reproductive Potential: Pregnancy testing: Verify pregnancy status of females of reproductive potential prior to initiation of ENHERTU. Contraception: Females: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with ENHERTU and for 7 months after the last dose. Males: 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. Infertility: ENHERTU may impair male reproductive function and fertility.
• Pediatric Use: Safety and effectiveness of ENHERTU have not been established in pediatric patients.
• Geriatric Use: Of the 883 patients with breast cancer treated with ENHERTU 5.4 mg/kg, 22% were ≥65 years and 3.6% were ≥75 years. No overall differences in efficacy within clinical studies were observed between patients ≥65 years of age compared to younger patients. There was a higher incidence of Grade 3-4 adverse reactions observed in patients aged ≥65 years (60%) as compared to younger patients (48%). Of the 101 patients with unresectable or metastatic HER2-mutant NSCLC treated with ENHERTU 5.4 mg/kg, 40% were ≥65 years and 8% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Of the 125 patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg in DESTINY-Gastric01, 56% were ≥65 years and 14% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients.
• Renal Impairment: A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Monitor patients with moderate renal impairment more frequently. The recommended dosage of ENHERTU has not been established for patients with severe renal impairment (CLcr <30 mL/min).
• Hepatic Impairment: In patients with moderate hepatic impairment, due to potentially increased exposure, closely monitor for increased toxicities related to the topoisomerase inhibitor. The recommended dosage of ENHERTU has not been established for patients with severe hepatic impairment (total bilirubin >3 times ULN and any AST).

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.

• 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 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.

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. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/L-1 blocking antibody prior to or after an allogeneic HSCT.
