Phase 3 Study Comparing Tarlatamab Plus Durvalumab, Carboplatin, and Etoposide Versus Durvalumab, Carboplatin, and Etoposide Alone in First-Line Treatment of Extensive Stage Small-Cell Lung Cancer

What this Trial Is About

Researchers are evaluating the effectiveness of combining tarlatamab with durvalumab, carboplatin, and etoposide compared to the combination of durvalumab, carboplatin, and etoposide alone in treating patients with untreated extensive stage small-cell lung cancer ES-SCLC. The main goal is to see if the addition of tarlatamab can help patients live longer overall. This is a phase 3, open-label, randomized study conducted across multiple centers. Participants are assigned to one of two groups. One group receives tarlatamab combined with durvalumab, carboplatin, and etoposide for four treatment 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 as intravenous infusions. The study lasts up to approximately 3.5 to 4 years to assess survival and disease progression. During the study, participants will undergo regular assessments including evaluations of overall survival and progression-free survival. Other measures include response to treatment, disease control, duration of response, and monitoring for treatment-related adverse events. Blood tests will evaluate drug levels and antibody development. The research team will carefully monitor participants throughout the treatment and follow-up periods, keeping track of their health and any side effects.
