AZ received one more approval in Japan, received approval of Imfinzi for SCLC

The Japanese Ministry of Health, Labor, and Welfare approved AstraZeneca’s Imfinzi (durvalumab) for treating patients with extensive-stage small-cell lung cancer (ES-SCLC). The drug is administered in combination with etoposide plus platinum chemotherapy (either carboplatin or cisplatin).

The approval is based on the Phase 3 CASPIAN trial, which enrolled 805 patients. The trial demonstrated a statistically significant improvement in the overall survival compared to chemotherapy. Patients were randomized in 1:1:1 ratio, durvalumab plus platinum–etoposide; durvalumab plus tremelimumab plus platinum–etoposide; or platinum–etoposide alone. Overall survival is considered as the primary endpoint. Durvalumab plus platinum–etoposide showed statistical improvement in the overall survival; median overall survival was 13 months in the durvalumab plus platinum-etoposide arm compared to 10.3 months in the platinum-etoposide group. The CASPIAN is a multicenter trial conducted across 23 countries, which included several locations in Japan.
