Study of Bevacizumab in Combination With Chemoimmunotherapy and Atezolizumab in Patients With Extensive Stage Small Cell Lung Cancer and Liver Metastases

Summary

This clinical trial aims to assess whether the addition of bevacizumab to atezolizumab and chemotherapy can improve response to treatment and progression-free survival in patients with extensive-stage small cell lung cancer (ES-SCLC) with liver metastases. The main questions it aims to answer are: * In patients with ES-SCLC with liver metastases, can bevacizumab in combination with atezolizumab and chemotherapy prolong the length of time that the cancer does not progress? * Is bevacizumab safe and tolerable when combined with atezolizumab and chemotherapy in patients with ES-SCLC and liver metastases? The study treatment includes two phases: * Induction phase: bevacizumab will be administered in combination with atezolizumab and chemotherapy on a 21-day cycle for four cycles. * Maintenance: atezolizumab and bevacizumab will be administered every 21 days for up to 12 months, or until unacceptable toxicity or disease progression. Participants will undergo blood tests every 3 weeks and tumor assessments every 6 weeks.
