Study Investigating Tarlatamab (AMG 757) in Patients With Metastatic/Locally Advanced Small-Cell Lung Cancer (SCLC) and Other Poorly Differentiated Neuroendocrine Carcinomas (NECs), With Biomarker Analysis to Characterize Response/Resistance (UNLOCK TARLATAMAB)
Is NCT07016230 recruiting? Yes, currently enrolling (Jun 2026). This Phase 2 trial studies Tarlatamab for metastatic/locally advanced small-cell lung cancer.
Treatment: Tarlatamab — UNLOCK TARLATAMAB is an open-label, single arm, multicenter, phase 2 platform study that aims to evaluate the mechanisms of action and resistance to tarlatamab in metastatic/locally advanced Small-Cell Lung Cancer (SCLC) with any level of DLL3 expression and in other poorly differentiated Neuroendocrine Carcinomas (NECs) DLL3 positive. The two cohorts of patients are the following: i. cohort 1: patients with SCLC with any level of DLL3 expression. ii. cohort 2: patients with other poorly differentiated NECs whatever the primary or high grade medullary thyroid carcinoma (MTC, capped at 4 patients) DLL3 positive by immunohistochemistry (IHC). Patients enrolled in both cohorts will receive treatment with tarlatamab at the dose of 1 mg on D1, 10 mg on D8 and D15 and Q2W thereafter in a 28-day cycle. Tarlatamab will be administrated in intravenous route until disease progression, unacceptable toxicity, or consent withdrawal. Tumor and blood samples will be collected at baseline, on-treatment and at progression in order to identify biomarkers of drug response
