SCLC Tarlatamab Blood Collection

August 3, 2026 updated by: Duke University

Analysis of Blood Samples in Small Cell Lung Cancer Patients Treated With Tarlatamab

The overall objective of this project is to prospectively collect blood samples throughout treatment with tarlatamab in patients with small cell lung cancer (SCLC). These samples will then be analyzed through a variety of assays to better characterize tarlatamab in the real-world setting.

The investigators will prospectively collect blood samples from 25 patients on days 1, 8, and 15 of tarlatamab treatment, as well as after each interval scan for disease monitoring. The investigators will also collect patient data including demographics and baseline characteristics, primary diagnosis, treatment history, and disease monitoring and progression.

Outcome Measure
Measure Description
Time Frame
Number of blood samples collected to better characterize tarlatamab in real-world setting
Time Frame: Days 1, 8, and 15 of tarlatamab and after each interval scan for disease assessment
Studies to better understand tarlatamab may include, but are not limited to, the following: 1) predictors of response to treatment with tarlatamab, 2) identification of predictive biomarkers for the development of cytokine release syndrome (CRS) and/or immune effector cell-associated neurotoxicity syndrome (ICANS), 3) characterization of the immune cell environment induced by tarlatamab, 4) identification of resistance mechanisms to tarlatamab treatment, and 5) development of potential translational correlates.
