- All
- Target Recruitment
- 181
- Age ≥20 years old in Japan, ≥18 years old in other countries
- Pathologically documented unresectable and/or metastatic non-squamous NSCLC
- Has relapsed from or is refractory to standard treatment or for which no standard treatment is available
- For Cohort 1 and Cohort 1a: HER2-overexpression (IHC 2+ or 3+) status must be assessed and confirmed by Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory or equivalent, from an archival tumor tissue sample
- For Cohort 2 only: Participant has any known documented activating HER2 mutation from an archival tumor tissue sample analyzed by CLIA laboratory or equivalent. Note: HER2 mutation documented only from a liquid biopsy sample cannot be used for enrollment.
- Presence of at least 1 measurable lesion assessed by the investigator and based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
- Is willing and able to provide an adequate archival tumor tissue sample
- Is willing to undergo a tissue biopsy, after the completion of the most recent treatment regimen
- Has Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 to 1
-
Had been previously treated with HER2-targeted therapies, except for pan-HER class tyrosine kinase inhibitors
-
For Cohort 1 and Cohort 1a: Has known HER2 mutation
-
Has a medical history of myocardial infarction, symptomatic congestive heart failure (CHF) (NYHA classes II-IV), unstable angina or serious cardiac arrhythmia
-
Has a history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids, or current ILD/pneumonitis, or suspected ILD/pneumonitis that cannot be ruled out due to imaging at screening
-
Has a QT interval corrected by Fridericia's formula (QTcF) prolongation to > 450 millisecond (ms) in males and > 470 ms in females
-
Has a medical history of clinically significant lung disease
-
Is suspected to have certain other protocol-defined diseases based on imaging at screening period
-
Has history of any disease, metastatic condition, drug/medication use or other condition that might, per protocol or in the opinion of the investigator, compromise:
- safety or well-being of the participant or offspring
- safety of study staff
- analysis of results

Group Intervention Description Cohort 1: HER2 Overexpressing Trastuzumab deruxtecan Participants with HER2-overexpressing(immunohistochemistry \[IHC\] 3+ or IHC 2+), unresectable and/or metastatic NSCLC adenocarcinoma who received 6.4 mg/kg trastuzumab deruxtecan (DS-8201a). Cohort 1a: HER2 Overexpressing Trastuzumab deruxtecan Participants with HER2-overexpressing (immunohistochemistry \[IHC\] 3+ or IHC 2+), unresectable and/or metastatic NSCLC adenocarcinoma who received 5.4 mg/kg trastuzumab deruxtecan (DS-8201a). Cohort 2: HER2 Mutated Trastuzumab deruxtecan Participants with HER2-mutated, unresectable and/or metastatic NSCLC who received 6.4 mg/kg trastuzumab deruxtecan (DS-8201a).
- Primary Outcome Measures
Name Time Method Percentage of Participants With Objective Response Rate (ORR) Based on Independent Central Review Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) The Objective Response Rate (ORR) was the defined as the percentage of participants who achieved a best overall response of confirmed Complete Response (CR) or Partial Response (PR), assessed by independent central review (ICR) committee based on RECIST version 1.1. CR was defined as a disappearance of all target lesions and PR was defined as at least a 30% decrease in the sum of diameters of target lesions. Confirmed ORR based on ICR is reported.
- Secondary Outcome Measures
Name Time Method Duration of Response (DoR) Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) Duration of Response (DoR) was defined as the time from the date of the first documentation of objective response (complete response \[CR\] or partial response \[PR\]) to the date of the first objective documentation of progressive disease (PD) or death due to any cause. DoR in participants with confirmed CR/PR based on independent central review and investigator assessment is reported.
Percentage of Participants With Disease Control Rate (DCR) Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) Disease Control Rate (DCR) was defined as the percentage of participants who achieved a best overall response of CR, PR, or stable disease (SD) during study treatment. Confirmation of CR/PR was required. DCR based on independent central review and investigator assessment is reported.
Progression-Free Survival (PFS) Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) Progression-free survival (PFS) was defined as the time from the date of enrollment to the earlier of the dates of the first objective documentation of disease progression (as per RECIST v1.1) or death due to any cause. Progressive disease was defined as at least a 20% increase in the sum of diameters of target lesions. PFS based on independent central review and investigator assessment is reported.
Overall Survival (OS) Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) Overall survival (OS) was defined as the time from the date of first dose of study drug to the date of death due to any cause.
Percentage of Participants With Objective Response Rate (ORR) Based on Investigator Assessment Following Treatment With DS8201a in Participants With HER2-Over-Expressing or -Mutated Non-Small-Cell Lung Cancer (NSCLC) Up to 36 months (data cut-off) The Objective Response Rate (ORR) was defined as the percentage of participants who achieved a best overall response of confirmed Complete Response (CR) or Partial Response (PR), assessed by investigator assessment based on RECIST version 1.1. CR was defined as a disappearance of all target lesions and PR was defined as at least a 30% decrease in the sum of diameters of target lesions. Confirmed ORR based on investigator assessment is reported.
