Clinical summary

Summary

The main objective of this study is to see whether treatment with durvalumab immunotherapy, carboplatin chemotherapy and etoposide chemotherapy is more effective when tarlatamab immunotherapy is also given.

Eligible participants will be randomly allocated to one of two treatment arms.

In the Experimental Arm, participants will recieve tarlatamab + durvalumab, carboplatin and etoposide for 4 cycles, followed by further treatment with tarlatamab and durvalumab.

In the Active Comparator Arm, participants will receive durvalumab, carboplatin and etoposide for 4 cycles, followed by further treatment with durvalumab,

All treatments will be administered as intravenous (IV) infusions. 

Conditions

This trial is treating people with extensive stage small cell lung cancer who have not received prior treatment for their advanced disease

  • Measurable disease as defined per RECIST 1.1.
  • Suitable to receive carboplatin, etoposide and durvalumab regimen as first-line treatment per investigator clinical assessment.
  • Minimum life expectancy ≥ 12 weeks.

Exclusion

  • Participants can have no history of other malignancy in the last 2 years.
  • Any symptomatic central nervous system (CNS) metastases, or leptomeningeal disease.
  • They will have no history of severe or life-threatening events to immune-mediated therapy.

  • They will not have had a myocardial infarction and/or symptomatic congestive heart failure (New York Heart Association > class II) within 6 months prior to first dose of study treatment.

Inclusion

  • Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).
