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

August 17, 2026 updated by: Novartis Pharmaceuticals

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.

Study Overview

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 declaring 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).

If no PFS event is observed, PFS will be censored at the date of the late adequate tumor assessment prior to data cut-off date and start of new anti-neoplastic therapy, whichever comes first.

PFS will be analyzed in the FAS population according to the assigned dose level combination and checkpoint inhibitor in Phase Ib and by treatment group in Phase II part. The PFS distribution will be estimated using the Kaplan-Meier method, and the Kaplan-Meier curves, medians and 95% confidence intervals of the medians will be presented for each dose level combination and checkpoint inhibitor in Phase Ib and by treatment group in Phase II part.

OS will be analyzed in the FAS population according to the assigned dose cohort and checkpoint inhibitor in Phase Ib. The OS distribution will be estimated using the Kaplan-Meier method, and the Kaplan-Meier curves, medians and 95% confidence intervals of the medians will be presented for each dose level combination and checkpoint inhibitor in Phase Ib Kaplan-Meier estimates with 95% confidence intervals every 6 months will be summarized as well by dose level combination, checkpoint inhibitor in Phase Ib and treatment group in Phase II part.
