Overview
This study is designed to assess the efficacy and safety of datopotamab deruxtecan (Dato-DXd) in combination with pembrolizumab versus pembrolizumab in combination with pemetrexed and platinum chemotherapy in participants with no prior therapy for advanced or metastatic non-squamous non-small cell lung cancer (NSCLC).
Description
The primary objectives of the study are Progression Free Survival (PFS) and Overall Survival (OS) as first line therapy in participants with programmed death-ligand 1 (PD-L1) TPS <50% and advanced or metastatic NSCLC without actionable genomic alternations.
Eligible participants will be randomized in a 1:1:1 ratio to a) Dato-DXd plus pembrolizumab plus platinum; b) Dato-DXd plus pembrolizumab; or c) pembrolizumab plus pemetrexed plus platinum. Platinum therapy will be either carboplatin or cisplatin at investigator discretion. The study will be divided into three periods: Screening Period (including tissue screening), Treatment Period, and Follow-up Period.

- Documented negative test results for epidermal growth factor receptor (EGFR), lymphoma kinase (ALK), and proto-oncogene1 (ROS1) actionable genomic alterations based on analysis of tumor tissue.
- No known actionable genomic alterations in neurotrophic tyrosine receptor kinase (NTRK), proto-oncogene B-raf (BRAF), rearranged during transfection (RET), mesenchymal-epithelial transition factor (MET), or other actionable driver kinases with locally approved therapies.
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 at
screening.
- Has an adequate treatment washout period before Cycle 1 Day 1.
- Is willing and able to participate in the collection of patient-reported outcomes (PRO) data.
Exclusion Criteria:
- Has received prior systemic treatment for advanced/metastatic NSCLC.
- Has received prior treatment with any of the following, including in the
adjuvant/neoadjuvant (for NSCLC) setting:
- Any agent, including an antibody-drug conjugate, containing a chemotherapeutic agent targeting topoisomerase I.
- TROP2-targeted therapy.
- Any anti-programmed death receptor-1 (PD-1), anti-PD-L1, or anti-PD-ligand 2 (L2) agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX40, CD137).
- Any other immune checkpoint inhibitors.
- Has received a live vaccine or live-attenuated vaccine within 30 days prior to the
first dose of study drug. For any participant receiving an approved severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine, please follow the vaccine label and/or local guidance.
- Has spinal cord compression or clinically active untreated central nervous system (CNS) metastases and/or carcinomatous meningitis.
- Uncontrolled or significant cardiovascular disease, including:
- Mean QT interval corrected for heart rate using Fridericia's formula (QTcF) interval >470 msec regardless of sex.
- Myocardial infarction within 6 months prior to randomization.
- Uncontrolled angina pectoris within 6 months prior to randomization.
- LVEF <50% by ECHO or MUGA scan within 28 days before randomization.
- New York Heart Association Class 2 to 4 congestive heart failure (CHF) at screening.
- Uncontrolled hypertension within 28 days before randomization.
- Clinically severe pulmonary compromise resulting from intercurrent pulmonary
illnesses.
- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy.
- History of another primary malignancy (beyond NSCLC) except for:
- Malignancy treated with curative intent and with no known active disease ≥3 years before the first dose of study treatment and of low potential risk for recurrence.
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
- Adequately treated carcinoma in situ without evidence of disease.
- Participants with a history of prostate cancer (tumor/node/metastasis stage) of Stage ≤T2cN0M0 without biochemical recurrence or progression.
- Has a history of severe hypersensitivity reactions to either the drugs or inactive
ingredients of Dato-DXd, pembrolizumab, carboplatin, cisplatin or pemetrexed.
- Has a history of severe hypersensitivity reactions to other monoclonal antibodies.
- Has known human immunodeficiency virus (HIV) infection that is not well controlled.
- Has active or uncontrolled hepatitis B or C infection.
- Female who is pregnant or breastfeeding or intends to become pregnant.
- Any other medical conditions, including cardiac disease or psychological disorders, and/or substance abuse.
- Has a history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening.
- Has active, known, or suspected autoimmune disease.
- Has clinically significant corneal disease.
- Has had an allogeneic tissue/solid organ transplantation.
- Has received prior radiotherapy ≤4 weeks of start of study intervention or more than 30 Gy to the lung within 6 months of Cycle 1 Day 1.
