This is an open-label, single arm, phase 2 trial enrolling patients with untreated Extensive-Stage Small-Cell Lung Cancer (ES SCLC), with a strong translational attitude.
The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
Male/female participants who are at least 18 years of age on the day of signing informed consent.
Cytologically/histologically confirmed diagnosis of SCLC per the Veterans Administration Lung Study Group (VALG) staging system will be enrolled in this study. Patients must have extensive stage (ES) SCLC defined as Stage IV (T any, N any, M 1a/b/c) by the American Joint Committee on Cancer, Eighth Edition.
Possibility of obtaining tissue sample, via a biopsy of the primary tumour or metastatic tumour tissue, within the 6 weeks prior to study entry. An archival biopsy is acceptable as long as there has been no intervening anticancer treatment since the time the biopsy was obtained to enrolment in this clinical study and as long as it was within 6 weeks of study entry. Tissue sample would consist of formalin-fixed, paraffin-embedded tumour tissue blocks, or, from formalin-fixed paraffin-embedded tumor tissue block, at least five re-cut, unstained sections of 5 μM thickness for immunohistochemical analysis and five unstained sections of 10 μM thickness for NGS, presented on slides or cell-block.
Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention.
Patients with a history of autoimmune-related hypothyroidism who are on thyroid replacement hormone are eligible for the study.
Patients with controlled Type 1 diabetes mellitus who are on an insulin regimen are eligible for the study.
