AstraZeneca PLC - Imfinzi approved in Japan for SCLC
Imfinzi approved in
extensive-stage small cell lung cancer
Only PD-1/PD-L1 immunotherapy to demonstrate both a significant survival benefit and improved response rate in combination with a choice of chemotherapies
AstraZeneca's Imfinzi (durvalumab) has been approved in

An updated analysis recently showed sustained efficacy for Imfinzi plus chemotherapy after a median follow up of more than two years (OS HR: 0.75; 95% CI 0.62-0.91; nominal p=0.0032), with median OS of 12.9 months versus 10.5 months for chemotherapy alone. The safety and tolerability for Imfinzi plus chemotherapy were consistent with the known safety profile of these medicines. No patients tested positive for treatment-emergent anti-drug antibodies to Imfinzi.
The efficacy and safety results for Japanese patients in the
Imfinzi, in combination with etoposide and either carboplatin or cisplatin, is also approved in the US and several other countries around the world for the treatment of ES-SCLC in the 1st-line setting and is currently under regulatory review in other countries. It was recently recommended for marketing authorisation in the EU for this indication.
As part of a broad development programme, Imfinzi is also being tested following concurrent chemoradiation therapy in patients with limited-stage SCLC in the Phase III ADRIATIC trial.
Small cell lung cancer
Lung cancer is the leading cause of cancer death among both men and women and accounts for about one fifth of all cancer deaths.4 In
Imfinzi is a human monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, countering the tumour's immune-evading tactics and releasing the inhibition of immune responses.
Imfinzi is approved in the curative-intent setting of unresectable, Stage III NSCLC after chemoradiation therapy in the US,
As part of a broad development programme, Imfinzi is also being tested as a monotherapy and in combinations including with tremelimumab, an anti-CTLA4 monoclonal antibody and potential new medicine, as a treatment for patients with NSCLC, SCLC, bladder cancer, head and neck cancer, liver cancer, biliary tract cancer, cervical cancer, ovarian cancer, endometrial cancer and other solid tumours.
AstraZeneca in lung cancer
AstraZeneca has a comprehensive portfolio of approved and potential new medicines in late-stage development for the treatment of different forms of lung cancer spanning different histologies, several stages of disease, lines of therapy and modes of action. AstraZeneca aims to address the unmet needs of patients with EGFR-mutated tumours as a genetic driver of disease, which occur in 10-15% of NSCLC patients in the US and EU and 30-40% of NSCLC patients in
AstraZeneca is committed to addressing tumour mechanisms of resistance through the ongoing Phase II trials SAVANNAH and ORCHARD, which are testing Tagrisso in combination with savolitinib, a selective inhibitor of c-MET receptor tyrosine kinase, along with other potential new medicines. Enhertu (trastuzumab deruxtecan), a HER2-directed antibody drug conjugate, is in development for the treatment of metastatic non-squamous HER2-overexpressing or HER2-mutated NSCLC, including trials in combination with other anticancer treatments. In addition, DS-1062, a trophoblast cell-surface antigen 2 (TROP2)-directed ADC, is in early development for the treatment of advanced NSCLC where TROP2 is overexpressed in the majority of tumours.11
An extensive Immuno-Oncology (IO) development programme focuses on lung cancer patients without a targetable genetic mutation, which represents up to three-quarters of all patients with lung cancer.12 Imfinzi, an anti-PDL1 antibody, is in development for patients with advanced disease (Phase III trials POSEIDON and PEARL) and for patients in earlier stages of disease, including potentially-curative settings (Phase III trials MERMAID-1, AEGEAN, ADJUVANT BR.31, PACIFIC-2, PACIFIC-4, PACIFIC-5, and ADRIATIC) both as monotherapy and in combination with tremelimumab and/or chemotherapy. Imfinzi is also in development in the Phase II trials NeoCOAST, COAST and HUDSON in combination with potential new medicines from the early-stage pipeline, including Enhertu.
AstraZeneca's approach to IO
IO is a therapeutic approach designed to stimulate the body's immune system to attack tumours. The Company's IO portfolio is anchored by immunotherapies that have been designed to overcome anti-tumour immune suppression. AstraZeneca is invested in using IO approaches that deliver long-term survival for new groups of patients across tumour types.
The Company is pursuing a comprehensive clinical-trial programme that includes Imfinzi as a monotherapy and in combination with tremelimumab in multiple tumour types, stages of disease, and lines of therapy, and where relevant using the PD-L1 biomarker as a decision-making tool to define the best potential treatment path for a patient. In addition, the ability to combine the IO portfolio with radiation, chemotherapy, small targeted molecules from across AstraZeneca's Oncology pipeline, and from research partners, may provide new treatment options across a broad range of tumours.
AstraZeneca in oncology
AstraZeneca has a deep-rooted heritage in oncology and offers a quickly growing portfolio of new medicines that has the potential to transform patients' lives and the Company's future. With seven new medicines launched between 2014 and 2020, and a broad pipeline of small molecules and biologics in development, the Company is committed to advance oncology as a key growth driver for AstraZeneca focused on lung, ovarian, breast and blood cancers.
By harnessing the power of four scientific platforms - Immuno-Oncology, Tumour Drivers and Resistance, DNA Damage Response and Antibody Drug Conjugates - and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and one day eliminate cancer as a cause of death.
AstraZeneca (LSE/STO/NYSE: AZN) is a global, science-led biopharmaceutical company that focuses on the discovery, development and commercialisation of prescription medicines, primarily for the treatment of diseases in three therapy areas - Oncology, Cardiovascular, Renal & Metabolism, and Respiratory & Immunology.
