A Phase 3, Open Label, Multicenter, Randomized Study of First Line Tarlatamab in Combination With Durvalumab, Carboplatin and Etoposide Versus Durvalumab, Carboplatin and Etoposide in Untreated Extensive Stage Small-Cell Lung Cancer (DeLLphi-312)

Summary
The main objective of the study is to compare the efficacy of tarlatamab in combination with durvalumab, carboplatin and etoposide to the combination of durvalumab, carboplatin and etoposide on prolonging overall survival (OS).

- Measurable disease as defined per RECIST 1.1.
- Suitable to receive carboplatin, etoposide and durvalumab regimen as first-line treatment per investigator clinical assessment.
- Minimum life expectancy ≥ 12 weeks.
Exclusion Criteria9
- Participants can have no history of other malignancy in the last 2 years.
- Any symptomatic central nervous system (CNS) metastases, or leptomeningeal disease.
- They will have no history of severe or life-threatening events to immune-mediated therapy.
