A Phase Ib/II Dose Finding Study Assessing Safety and Efficacy of [177Lu]Lu-DOTA-TATE in Newly Diagnosed Extensive Stage Small Cell Lung Cancer (ES-SCLC) in Combination With Carboplatin, Etoposide, and Atezolizumab in Induction and With Atezolizumab in Maintenance Phase
This study aims to establish a safe and well tolerated dose of \[177Lu\]Lu-DOTA-TATE in combination with carboplatin, etoposide and atezolizumab in this setting and to assess preliminary efficacy of this combination treatment versus the combination of carboplatin, etoposide, and atezolizumab.The study will be essential to assess a new potential therapeutic option in participants with this aggressive cancer type.
