Interventions

  • Tarlatamab — DRUG
    All subjects will receive a step dose (1 mg tarlatamab) on cycle 1 day 1 administered as a 60-minute intravenous (IV) infusion then 10 mg tarlatamab IV administered on cycle 1 day 8, cycle 1 day 15, and every 2 weeks (Q2W) thereafter.

Study Details

Extrapulmonary small cell carcinoma (EPSCC) or neuroendocrine carcinoma (NEC) is a rare but fatal disease. The prognosis of patients with advanced EPSCC or NEC failed platinum-etoposide chemotherapy is poor with median overall survival ranged 6 to 9 months. High expression levels of DLL3 has been demonstrated in many EPSCC or NEC. As tarlatamab, a bispecific T-cell engager with dual affinity for DLL3 on tumor cells and CD3 on T cells, has demonstrated clinically meaningful activity for patients with advanced small cell lung cancer. We thus hypothesize that tarlatamab also has clinically activity for patients with advanced EPSCC and NECs.
