TROP2 NMR Concordance Study

Because our study is a cross-sectional study, no Discontinuation criteria were set for stage 1&stage2. The target of stage2 is to accrue a minimum of 1,000 positive samples and 1,000 negative samples at the central lab. Enrollment will be terminated once these accrual targets are achieved; no further specimens will be collected thereafter, even if the total number of specimens does not reach 2,800, or it is also possible that the final enrollment may exceed 2,800 participants.

Inclusion criteria

• Age ≥18 years at sampling.
• Histologically or cytologically documented non squamous NSCLC including:

• Stage IIIB or IIIC disease not amenable for surgical resection or definitive chemoradiation, or Stage IV metastatic NSCLC disease at the time of sampling who have not received any systemic therapy for first-line Stage IIIB, IIIC or IV NSCLC.

Participants who provide surgical samples for early-stage disease (Stage I to IIIA) are eligible. The capping for surgical samples is 70% and biopsy samples 30%.

• 2. (b) Lacks sensitising EGFR tumour tissue mutation (eg, exon 19 deletion or exon 21 L858R, exon 21 L861Q, exon 18 G719X, or exon 20 S768I mutation), as well as ALK and ROS1 rearrangements.

(c) Has no documented tumour genomic alteration results in NTRK, BRAF, RET, MET or HER2, KRAS oncogenes for which there are locally approved and available targeted first-line therapies.

(d) Participants have documented PD-L1 status with TPS (or TC).

• Willing to provide and have adequate tissue samples for biomarker testing, at least ≥5 FFPE slides for Stage 1, and at least ≥7 FFPE slides for Stage 2. Archival surgical samples less than 2 years before enrollment are eligible.
• Informed Consent: Signed inform consent form or waived inform consent per EC requirements.
• -1.Age ≥18 years at sampling.
• 2.Histologically or cytologically documented non squamous NSCLC including:
• (a)Stage IIIB or IIIC disease not amenable for surgical resection or definitive chemoradiation, or Stage IV metastatic NSCLC disease at the time of sampling who have not received any systemic therapy for first-line Stage IIIB, IIIC or IV NSCLC.
• Participants who provide surgical samples for early-stage disease (Stage I to IIIA) are eligible. The capping for surgical samples is 70% and biopsy samples 30%.
• (b)Lacks sensitising EGFR tumour tissue mutation (eg, exon 19 deletion or exon 21 L858R, exon 21 L861Q, exon 18 G719X, or exon 20 S768I mutation), as well as ALK and ROS1 rearrangements.
• (c)Has no documented tumour genomic alteration results in NTRK, BRAF, RET, MET or HER2, KRAS oncogenes for which there are locally approved and available targeted first-line therapies.
• (d) Participants have documented PD-L1 status with TPS (or TC).
• 3. Willing to provide and have adequate tissue samples for biomarker testing, at least ≥5 FFPE slides for Stage 1, and at least ≥7 FFPE slides for Stage 2. Archival surgical samples less than 2 years before enrollment are eligible.
• 4. Informed Consent: Signed inform consent form or waived inform consent per EC requirements.

Exclusion criteria

• Mixed small-cell lung cancer and NSCLC histology; sarcomatoid variant of NSCLC.
• At the time of tissue acquisition, the subject has the following known conditions: active tuberculosis infection, or clinically severe pulmonary function compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder (eg, pulmonary emboli within 3 months of the study enrollment, severe asthma, severe COPD, restrictive lung disease, pleural effusion, etc.).
• 1. Mixed small-cell lung cancer and NSCLC histology; sarcomatoid variant of NSCLC.
