A Study of [177Lu]Lu-DOTA-TATE in Newly Diagnosed ES-SCLC Patients in Combination With Carboplatin, Etoposide and Atezolizumab

Purpose

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.

Detailed Description

The study for each participant consists of a Screening period, a Treatment period that includes an Induction treatment period and a Maintenance treatment period, and a Follow-up period. The study will consist of a Phase Ib dose escalation with concurrent backfill part and a randomised controlled Phase II part. During the screening period of up to 28 days before starting SCLC treatment, each participant will be assessed for somatostatin receptor (SSTR) expression by [68Ga]Ga-DOTA-TATE imaging PET/scan. The dose escalation part in this study will be guided by the dose limiting toxicity (DLT) rate observed during the DLT period. To achieve a more robust dataset and to aid dose decisions, additional participants may be backfilled in each dose level. Upon dedclaring RD, a 1:1 randomised Phase II with approximately 140 participants with newly diagnosed ES-SCLC will be enrolled and receive either [177Lu]Lu-DOTA-TATE at the RD in combination with carboplatin, etoposide and atezolizumab (experimental arm) or carboplatin, etoposide and atezolizumab alone (control arm).
