The KESTREL Phase III trial for AstraZeneca’s Imfinzi (durvalumab) did not meet the primary endpoint of improving overall survival (OS) versus the EXTREME treatment regimen (chemotherapy plus cetuximab), a standard of care, in the 1st-line treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) whose tumours expressed high levels of PD-L1. Also, the combination of Imfinzi plus tremelimumab did not indicate an OS benefit in ‘all-comer’ patients, a secondary endpoint. Dave Fredrickson, Executive Vice President, Oncology Business Unit, said: “Metastatic head and neck cancer is a complex and challenging disease with a poor prognosis. While we are disappointed by these results, insights from the KESTREL Phase III trial will advance our understanding and application of immunotherapy across our clinical development programme. We will continue to build on the established benefits of Imfinzi in early lung cancer and small cell lung cancer, to bring immunotherapy treatment options to all patients who may benefit.” The safety and tolerability profiles for Imfinzi as a monotherapy and in combination with tremelimumab were consistent with previous trials. The data will be shared in due course.
