About this trial
The study is a non-interventional evaluation of participants with extensive stage (ES) SCLC who will receive diagnostic and (where possible) post-progression tumor tissue profiling, alongside plasma ctDNA and CTC biomarker profiling during standard of care therapy in both first and second line treatment.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Histologically confirmed small cell lung cancer diagnosis
Diagnosis made with excisional or core needle biopsy specimen (fine needle aspirate may be permitted with approval from the Medical Monitor)
Subjects must submit tumor sample per the laboratory manual, defined as follows: 1L Cohort - Tissue obtained prior to the initiation of 1L therapy; 2L Cohort - Tissue obtained prior to the initiation of 1L therapy and/or a standard of care re-biopsy prior to the start of 2L therapy, if performed.
ECOG performance status of 0-2 at time of enrollment

Trial outcomes
Primary outcomes
To determine if tumor tissue transcriptional subtypes can be detected
To determine prospectively if SCLC tumor tissue transcriptional subtypes can be detected by RNAseq
To characterize relationship between tissue transcriptional subtype and clinical outcomes
To characterize the relationship between tissue transcriptional subtype and clinical outcomes for first and second line based on collection of longitudinal information from medical records
Secondary outcomes
To characterize the relationship between longitudinal ctDNA methylation and CTC results with clinical outcomes for first and second line therapy based on collection of longitudinal information from medical records
To evaluate the relationship between initial molecular SCLC subtypes (e.g., SCLC-A, SCLC-N, SCLC-I) and the subsequent development of therapeutic resistance
To longitudinally evaluate the relationship between initial molecular SCLC subtypes (e.g., SCLC-A, SCLC-N, SCLC-I) and the subsequent development of therapeutic resistance, identifying the specific genomic and cellular mechanisms (e.g., non-NE phenotypic emergence) that occur during clinical progression on first- and second-line treatments
Other outcomes
To identify biomarkers and mechanisms of progression
To test the feasibility of longitudinally detecting transcriptional SCLC subtype related biomarkers from ctDNA methylation and to correlate these results with other longitudinal liquid biopsy findings (ctDNA and CTCs) during therapy to assess if changes are detectable prior to progression
To determine feasibility of longitudinal collection of CTCs and ctDNA during first and second line therapy
To determine the feasibility of longitudinal collection and multiomic analysis of CTCs and ctDNA during first-line and second-line therapy in SCLC patients to define the evolution of transcriptional subtypes over longitudinal collections with the pressure of therapy across multiple lines of therapy
To test feasibility of transcriptional subtyping from tissue collected from different metastatic sites compared to the primary site
To describe specific methylation biomarkers of SCLC subtypes
