A Phase 3, Open Label, Randomized Study Comparing First-Line Tarlatamab Combined With Durvalumab, Carboplatin, and Etoposide Versus Durvalumab, Carboplatin, and Etoposide in Untreated Extensive Stage Small-Cell Lung Cancer

What this Trial Is About

Researchers are comparing the effectiveness of a combination treatment including tarlatamab, durvalumab, carboplatin, and etoposide to a similar combination without tarlatamab in people with untreated extensive stage small-cell lung cancer ES-SCLC. This Phase 3 study aims to see if adding tarlatamab can improve overall survival and progression-free survival in this patient group. The study is sponsored by Amgen and focuses on first-line treatment options for this aggressive cancer stage. Participants are assigned randomly to one of two groups. One group will receive tarlatamab combined with durvalumab, carboplatin, and etoposide for four cycles, followed by maintenance treatment with tarlatamab and durvalumab. The other group receives durvalumab, carboplatin, and etoposide for four cycles, followed by durvalumab alone. All drugs are given through intravenous infusions. The study is open-label, meaning both participants and researchers know which treatment is being given. During the study, participants will be monitored up to approximately 3.5 years for overall survival and progression-free survival through blinded independent central review. Additional outcomes like objective response, disease control, duration of response, and treatment-related side effects will be tracked for up to four years. Blood samples will be taken to measure tarlatamab levels and to check for antibodies against the drug. Safety and treatment effects are carefully recorded throughout the study period.
