FDA Approves AstraZeneca’s Imfinzi in Lung Cancer
FDA has approved AstraZeneca’s Imfinzi (durvalumab) for treating patients with Stage III non-small cell lung cancer whose tumors are not able to be surgically removed and whose cancer has not progressed after treatment with chemotherapy and radiation. This is the first treatment approved for this disease stage to reduce the risk of the cancer progressing, when the cancer has not worsened after chemoradiation, FDA Oncology Center of Excellence Richard Pazdur says in a release. “Although a small number of patients may be cured with the chemoradiation, the cancer may eventually progress,” he says. “Patients now have an approved therapy that has been shown to keep the cancer from progressing for a longer time after chemoradiation.”
Approval was based on data from a randomized trial of 713 patients. “The median progression-free survival for patients taking Imfinzi was 16.8 months compared to 5.6 months for patients receiving a placebo,” FDA says. In addition, AstraZeneca agreed to a post-marketing commitment to provide additional information from their study about how long patients lived following treatment with Imfinzi after chemotherapy and radiation (overall survival).
