- monoclonal antibody/immune checkpoint inhibitor. Durvalumab (MEDI4736) is a human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumours avoid detection by the immune system. MEDI4736 blocks these signals, countering the tumour’s immune-evading tactics.This antibody is directed against B7-H1, have been shown to block the interaction between B7-H1 and its receptors, PD-1 and CD80 (B7-1). This blockade may help to overcome the immunosuppressive effects of B7-H1 on anti-tumor T cells.
- AstraZeneca recently received accelerated approval from the US FDA for Imfinzi® in previously treated patients with advanced bladder cancer. The antibody is also being tested in the 1st-line treatment of patients with NSCLC as monotherapy in the MYSTIC and PEARL Phase III trials. It is also being developed in combination with tremelimumab, a checkpoint inhibitor that targets CTLA-4, as part of the MYSTIC, NEPTUNE and POSEIDON Phase III trials.

- locally-advanced, unresectable non-small cell lung cancer (NSCLC) whose disease has not progressed following platinum-based chemoradiation therapy
- • On February 16, 2018, the FDA approved Imfinzi® (durvalumab) for the treatment of patients with stage III non-small cell lung cancer (NSCLC) whose tumors are not able to be surgically removed (unresectable) and whose cancer has not progressed after treatment with chemotherapy and radiation (chemoradiation).
“This is the first treatment approved for stage III unresectable non-small cell lung cancer to reduce the risk of the cancer progressing, when the cancer has not worsened after chemoradiation,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research.
- The approval of Imfinzi® for the treatment of stage III, unresectable NSCLC was based on a randomized trial of 713 patients whose cancer had not progressed after completing chemotherapy and radiation (PACIFIC trial). The trial measured the length of time the tumors did not have significant growth after starting treatment with Imfinzi or a placebo (progression-free survival). The median progression-free survival for patients taking Imfinzi® was 16.8 months compared to 5.6 months for patients receiving a placebo. In addition, the sponsor has agreed to a post-marketing commitment to provide additional information from their study to the FDA about how long patients lived following treatment with Imfinzi after chemotherapy and radiation (overall survival).
Common side effects of Imfinzi® in patients with stage III unresectable NSCLC include cough, fatigue, inflammation in the lungs (pneumonitis/radiation pneumonitis), upper respiratory tract infections, difficulty breathing (dyspnea) and rash. Serious risks of Imfinzi® include immune-mediated side effects, where the body’s immune system attacks healthy cells or organs, such as the lungs (pneumonitis), liver (hepatitis), colon (colitis), hormone-producing glands (endocrinopathies) and kidneys (nephritis). Other serious side effects of Imfinzi include infection and infusion-related reactions. Imfinzi can cause harm to a developing fetus; women should be advised of the potential risk to the fetus and to use effective contraception.
- • On October 9, 2017, AstraZeneca has announced that the European Medicines Agency (EMA) has accepted a Marketing Authorisation Application (MAA) for Imfinzi® (durvalumab) for the treatment of patients with locally-advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) whose disease has not progressed following platinum-based chemoradiation therapy. This is the first registrational submission for Imfinzi® in the European Union.
- The MAA submission is based on positive progression-free survival (PFS) data from the Phase III PACIFIC trial. The trial continues to evaluate overall survival (OS), its other primary endpoint. Detailed results of the PACIFIC trial, including additional safety information, were published online in the New England Journal of Medicine.
• On July 31, 2017, AstraZeneca and MedImmune, its global biologics research and development arm, announced that the FDA has granted Breakthrough Therapy Designation for Imfinzi® (durvalumab) for the treatment of patients with locally-advanced, unresectable non-small cell lung cancer (NSCLC) whose disease has not progressed following platinum-based chemoradiation therapy.
- The Breakthrough Therapy Designation for Imfinzi® was granted on the basis of interim results from the Phase III PACIFIC trial, a randomised, double-blinded, placebo-controlled multi-centre trial of Imfinzi® as sequential treatment in patients with locally-advanced, unresectable (Stage III) NSCLC who had not progressed following standard platinum-based chemotherapy concurrent with radiation therapy. This is the fourth Breakthrough Therapy Designation AstraZeneca has received from the FDA for a New Oncology cancer medicine over the past three years, the second for Imfinzi®.
