AstraZeneca and MedImmune, its global biologics research and development arm, announced that the US Food and Drug Administration (FDA) has granted Breakthrough Therapy designation (BTD) for durvalumab (MEDI4736), an investigational human monoclonal antibody directed against programmed death ligand-1 (PD-L1), for the treatment of patients with PD-L1 positive inoperable or metastatic urothelial bladder cancer whose tumour has progressed during or after one standard platinum-based regimen.
The Breakthrough Therapy designation for durvalumab was granted by the FDA on the basis of early clinical data from a Phase I trial (Study 1108) in patients with advanced metastatic urothelial bladder cancer whose tumour has progressed during or after one standard platinum-based regimen. This represents the third Breakthrough Therapy designation AstraZeneca has received from the FDA for medicines in Oncology. This designation offers the opportunity for further collaboration with the FDA for the durvalumab development programme. Data from study 1108 have been submitted for presentation at a future medical meeting.
Durvalumab is also being tested in first-line bladder cancer as a monotherapy as well as in combination with tremelimumab as part of the DANUBE Phase III trial which achieved first patient in during the final quarter of 2015.
