Sacituzumab Tirumotecan (MK-2870) Versus Chemotherapy in Previously Treated Advanced or Metastatic Nonsquamous Non-small Cell Lung Cancer (NSCLC) With EGFR Mutations or Other Genomic Alterations (MK-2870-004)

Phase 3
Recruiting
Conditions
Non-small Cell Lung Cancer (NSCLC)
Interventions
Registration Number
NCT06074588
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The purpose of this study is to evaluate sacituzumab tirumotecan versus chemotherapy (docetaxel or pemetrexed) for the treatment of previously-treated non-small cell lung cancer (NSCLC) with exon 19del or exon 21 L858R EGFR mutations (hereafter referred to as EGFR mutations or EGFR-mutated) or any of the follow genomic alterations: ALK gene rearrangements, ROS1 rearrangements, BRAF V600E mutations, NTRK gene fusions, MET exon 14 skipping mutations, RET rearrangements, or less common EGFR point mutations of exon 20 S768I, exon 21 L861Q, or exon 18 G719X mutations. The primary hypotheses are that sacituzumab tirumotecan is: (1) superior to chemotherapy with respect to progression-free survival (PFS) per RECIST 1.1 as assessed by BICR in NSCLC with EGFR mutations; and (2) superior to chemotherapy with respect to overall survival (OS) in NSCLC with EGFR mutations.

Change in Score from Baseline in Dyspnea Score (EORTC QLQ-C30 Item 8)Baseline and up to approximately 48 weeks

The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant response to the question "Were you short of breath?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a worse level of dyspnea. The change from baseline in the dyspnea (EORTC QLQ-C30 Item 8) score will be presented.
