A Phase 2 Study of Tarlatamab in Patients With Small Cell Lung Cancer (SCLC)

Phase 2
Active, not recruiting
Conditions
Relapsed/Refractory Small Cell Lung Cancer
Interventions
Registration Number
NCT05060016
Lead Sponsor
Amgen
Brief Summary

The main aim of this study is to:

* evaluate safety and efficacy (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST 1.1\] by investigator) of 2 dose levels of tarlatamab for Part 1 only

* evaluate anti-tumor activity of tarlatamab as determined by objective response rate (ORR) per RECIST 1.1 by blinded independent central review (BICR) for Part 1 and 2

* evaluate safety of reduced mandatory monitoring period in Cycle 1 at selected dose of tarlatamab for Part 3

  • Unresolved toxicity from prior anti-tumor therapy, defined as per protocol.

Other Medical Conditions

  • History of other malignancy within the past 2 years, with exceptions
  • Myocardial infarction and/or symptomatic congestive heart failure (New York Heart Association > class II) within 12 months of first dose of tarlatamab.
  • History of arterial thrombosis (eg, stroke or transient ischemic attack) within 12 months of first dose of tarlatamab.

    1. Screening and during study treatment: Live and live-attenuated vaccines are prohibited within 28 days prior to the first dose of tarlatamab and for the duration of the study. Live viral non-replicating vaccine (e.g. Jynneos) for Monkeypox infection is allowed during the study (except during cycle 1) in accordance with local standard of care and institutional guidelines.
    2. End of study treatment: Live and live-attenuated vaccines can be used when at least 42 days (5X half-life of tarlatamab) have passed after the last dose of tarlatamab.
