"MedImmune, the global biologics research and development arm of AstraZeneca, presented results today from its novel investigational immunotherapy portfolio, focusing on MEDI4736, at the American Society of Clinical Oncology (ASCO) 2014 Annual Meeting. Overall, studies demonstrated durable clinical activity and tolerability for MEDI4736 across a range of tumor types.
"This announcement follows the recent progression of the first Phase III study for MEDI4736, an investigational, engineered, human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumors avoid detection by the immune system. It is believed that by targeting PD-L1, MEDI4736 may block this ligand from sending out signals to T-cells to ‘ignore’ tumor cells, thereby countering cancer’s immune-evading tactics.
Editor's note: Immunotherapy treatments that boost a patient's own immune system to fight cancer are a promising area of cancer research. A new immunotherapy drug called MEDI4736 is being tested in volunteer patients with different cancer types, and has shown good results for some patients with advanced non-small cell lung cancer (NSCLC).
