Study Evaluating Safety, Tolerability and Pharmacokinetics (PK) of Tarlatamab in Adults With Small Cell Lung Cancer (SCLC)

Phase 1
Active, not recruiting
Conditions
Small Cell Lung Carcinoma
Interventions
Drug: CRS Mitigation Strategies
Registration Number
NCT03319940
Lead Sponsor
Amgen
Brief Summary

A study to assess the safety, tolerability, and PK of tarlatamab in participants with SCLC

Detailed Description

This is an open-label, ascending, multiple doses, phase 1 study evaluating tarlatamab monotherapy, in combination with anti-PD1 therapy and with additional cytokine release syndrome (CRS) mitigation strategies. Tarlatamab will be administered as a short term intravenous (IV) infusion in participants with SCLC. Tarlatamab is a Half-Life Extended (HLE) Bispecific T cell engager (BiTE®) targeting delta-like protein 3 (DLL3)

Exclusion Criteria
  • History of other malignancy within the past 2 years prior to first dose of tarlatamab with exceptions
  • Major surgery within 28 days of first dose tarlatamab
  • Untreated (includes new lesions or progression in previously treated lesions) or symptomatic brain metastases and leptomeningeal disease (regardless of symptomatic or not).
  • Prior anti-cancer therapy: at least 28 days must have elapsed between any prior anti-cancer therapy and first dose of tarlatamab with the following exceptions: participants who received conventional chemotherapy are eligible if at least 14 days have elapsed and if all treatment-related toxicity has been resolved to Grade less than or equal to 1; and prior palliative radiotherapy must have been completed at least 7 days before the first dose of tarlatamab
  • Participants who experienced severe, life-threatening or recurrent (Grade 2 or higher) immune-mediated AEs or infusion-related reactions including those that lead to permanent discontinuation while on treatment with immune-oncology agents
  • Has evidence of interstitial lung disease or active, non-infectious pneumonitis
  • Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of tarlatamab
  • Part C only: history of solid organ transplantation or active autoimmune disease that has required systemic treatment within the past 2 years
  • Participant with symptoms and/or clinical signs and/or radiographic signs that indicate an acute and/or uncontrolled active systemic infection within 7 days prior to the first dose of investigational product administration
