A Study to Evaluate the Optimal Dose, Adverse Events and Change in Disease Activity of Intravenous ABBV-706 in Combination With Atezolizumab Versus Standard of Care as First-Line Treatment in Adult Participants With Previously Untreated Extensive Stage Small Cell Lung Cancer
Small cell lung cancer (SCLC) is characterized by aggressive and rapid growth and a tendency to develop early spread to distant sites including mediastinal lymph nodes, liver, bones, adrenal glands, and brain. The purpose of this study is to assess safety, dose, change in disease activity of ABBV-706 given with atezolizumab, compared to standard of care (SOC) treatment (etoposide, carboplatin, atezolizumab, and optional lurbinectedin).
ABBV-706 is an investigational drug being developed for the treatment of SCLC. There are multiple treatment arms in this study. Participants will either receiv
