Phase 3RecruitingAmgenNCT07778316Data as of Sep 2026Location: United States · China

Treatment: TarlatamabThe 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.
