AGNOSTIC THERAPY IN A PHASE II SINGLE-ARM STUDY IN FIRST-LINE TREATMENT OF DURVALUMAB IN ASSOCIATION WITH CARBOPLATIN OR CISPLATIN AND ETOPOSIDE IN PATIENTS AFFECTED BY EXTENSIVE STAGE - EXTRAPULMONARY SMALL CELL CARCINOMA

"All drugs will be administered intravenously. Induction treatment will be administered on a 21-day cycle for four cycles and will consist of:~* etoposide 80-100 mg/m² (administered on days 1-3 of each 21-day cycle);~* investigator's choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m² (administered on day 1 of each cycle);~* durvalumab 1500 mg every 3 weeks in combination with chemotherapy (induction phase) followed by maintenance phase with durvalumab 1500 mg every 4 weeks. Patients will continue treatment until disease progression per investigator assessment, unacceptable toxicity, or other discontinuation criteria were met for a maximum of 24 months. Continuation of study treatment after disease progression will be permitted if there is evidence of clinical benefit for a maximum 24 months."
