E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the Phase Ib portion of the study is to establish the recommended dose of [177Lu]Lu-DOTA-TATE in combination with carboplatin, etoposide, and atezolizumab in induction treatment and with atezolizumab in maintenance treatment in newly diagnosed participants with ES-SCLC. The primary objective of the Phase II portion of the study is to assess efficacy of [177Lu]Lu-DOTA-TATE in combination with carboplatin, etoposide and atezolizumab (experimental arm) versus standard of care consisting of carboplatin, etoposide, and atezolizumab (control arm) in terms of overall survival. |
|
E.2.2 | Secondary objectives of the trial |
Phase Ib: • To assess the preliminary anti-tumor activity of [177Lu]Lu-DOTA-TATE in combination with carboplatin, etoposide and atezolizumab in newly diagnosed participants with ES-SCLC • To characterize the pharmacokinetics (PK) and dosimetry of [177Lu]Lu-DOTA-TATE in participants with newly diagnosed participants with ES-SCLC
Phase II: • To evaluate the antitumor activity of [177Lu]Lu-DOTA-TATE in combination with carboplatin, etoposide and atezolizumab (experimental arm) versus standard of care consisting of carboplatin, etoposide, and atezolizumab (control arm)
Phase Ib and Phase II: • To characterize the safety and tolerability of [177Lu]Lu-DOTA-TATE in combination with carboplatin, etoposide, and atezolizumab in induction treatment and with atezolizumab in maintenance treatment in newly diagnosed participants with ES-SCLC • To assess the safety and tolerability of [68Ga]Ga-DOTA-TATE in participants with newly diagnosed ES-SCLC |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Key Inclusion Criteria: • Participant is ≥ 18 years on the day of signing informed consent form • Histologically or cytologically confirmed ES-SCLC • Presence of measurable disease (at least one target lesion) according to RECIST v1.1 assessed by conventional computed tomography (CT) scan • SSTR positive [68Ga]Ga-DOTA-TATE imaging positron emission tomography (PET) scan demonstrating uptake equal or higher than the liver uptake (uptake intensity score 2 or above in the visual uptake scoring scale) in at least one target or non-target lesion • No prior systemic treatment for ES-SCLC (except the first cycle of chemotherapy with or without atezolizumab of the induction period) • Provision of tumor tissue to support exploratory biomarker analysis • Life expectancy of >=6 months |
|
E.4 | Principal exclusion criteria |
Key exclusion Criteria: • Participant has received prior therapy with an antibody or drug against immune checkpoint pathways • Active leptomeningeal disease or uncontrolled, untreated brain metastasis • Any major surgical procedure requiring general anesthesia =< 28 days before Cycle 2 Day 1 • History of current diagnosis of electrocardiogram (ECG) abnormalities indicating significant risk of safety for participants participating in the study • Known hypersensitivity to the active substances or any of the excipients of the study drugs • Concurrent participation in another therapeutic clinical study

E.5 End points |
E.5.1 | Primary end point(s) |
Phase Ib: • Frequency of dose limiting toxicities (DLTs), incidence of adverse events (AEs), serious AEs (SAEs), and AEs leading to treatment discontinuation Phase II: • Overall Survival (OS) defined as time from date of randomization to death due to any cause |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Frequency of DLTs: Within the first 6 weeks of [177Lu]Lu-DOTA-TATE treatment Incidence of adverse events (AEs), serious AEs (SAEs), and AEs leading to treatment discontinuation: From date of randomization to 8 weeks following the last dose of study treatment
OS: Time from date of randomization to death due to any cause |
|
E.5.2 | Secondary end point(s) |
Phase Ib: • Objective Response Rate (ORR), Duration of Response (DOR), Progression-Free Survival (PFS), Overall Survival (OS) • Time activity curves (TACs), describing % of the activity injected vs time in blood, organs and tumor lesions. • Absorbed radiation doses of [177Lu]Lu-DOTA-TATE in organs and tumor lesions • Concentration of [177Lu]Lu-DOTA-TATE in blood over time and derived PK parameters • Quantification of [177Lu]Lu-DOTA-TATE excreted from the body in urine from the start of infusion until the first whole body planar imaging
Phase II: • Progression free survival (PFS) by investigator assessment, Objective Response Rate (ORR), Duration of Response (DOR) based on investigator assessment as per RECIST 1.1
Phase Ib and Phase II: • Incidence and severity of Adverse Events (AEs) and serious Adverse Events (SAEs) • Incidence and severity of Adverse Events (AEs) and serious Adverse Events (SAEs) within 48 hours after [68Ga]Ga-DOTA-TATE infusion |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
•Incidence and severity of AEs and SAEs - from randomization until 30 days after safety follow-up. •ORR, DOR, PFS, OS : from randomization until date of progression or date of death from any cause, whichever comes first •Time activity curves (TACs), absorbed radiation doses of [177Lu]Lu and concentration of [177Lu]Lu-DOTA-TATE in blood: week 7 day 3 •Quantification of [177Lu]Lu excreted from the body in urine: from the start of infusion until the first whole body planar imaging •Incidence and severity of AEs and SAEs of [68Ga]Ga: within 48h after administration |
