A Phase 3, Open-Label, Multicenter, Randomized Study of Subcutaneous vs Intravenous Tarlatamab in Participants With Relapsed Extensive-Stage Small Cell Lung Cancer After Platinum-based First-line Chemotherapy (DeLLphi-315)
The primary objective of this study is to demonstrate non-inferiority in pharmacokinetic (PK) parameters of subcutaneous (SC) vs intravenous (IV) tarlatamab administration and to characterize the efficacy, safety, and tolerability of SC tarlatamab in participants with relapsed extensive-stage small-cell lung cancer (ES-SCLC) after platinum-based chemotherapy.

• Histologically or cytologically confirmed SCLC with demonstrated progression or relapse.
• Participants who progressed or recurred following 1 platinum-based regimen.
• Measurable disease as defined per RECIST 1.1 within the 21-day screening period.
• Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1.
• Minimum life expectancy of 12 weeks.
• Adequate organ function.
• History of central nervous system (CNS) metastases are allowed with considerations defined in the protocol.
