Study of Trastuzumab Deruxtecan, Pembrolizumab, and Platinum-based Chemotherapy in First-line HER2 Overexpressing Non-small Cell Lung Cancer
(DESTINY-Lung06)
What this study is about
This clinical trial is designed to assess the effectiveness and safety of trastuzumab deruxtecan (T-DXd; Enhertu®) in combination with pembrolizumab versus platinum-based chemotherapy in combination with pembrolizumab in participants with no prior therapy for locally advanced unresectable or metastatic non-squamous NSCLC, whose tumors have HER2-overexpressing and PD-L1 TPS \<50% without known AGA that have locally available therapies targeting their AGAs in first-line advanced/metastatic setting.
View original scientific description
This clinical trial is designed to assess the efficacy and safety of trastuzumab deruxtecan (T-DXd; Enhertu®) in combination with pembrolizumab versus platinum-based chemotherapy in combination with pembrolizumab in participants with no prior therapy for locally advanced unresectable or metastatic non-squamous NSCLC, whose tumors have HER2-overexpressing and PD-L1 TPS \<50% without known AGA that have locally available therapies targeting their AGAs in first-line advanced/metastatic setting.
Interventions
DRUG
Trastuzumab Deruxtecan
T-DXd will be administered at a dose of 5.4 mg/kg intravenously (IV) every 3 weeks (Q3W)
DRUG
pembrolizumab
pembrolizumab will be administered at a dose of 200 mg IV Q3W
DRUG
Pemetrexed
Pemetrexed will be administered at a dose of 500 mg/m\^2 IV Q3W
DRUG
Platinum Chemotherapy
One of the following two will be administered in Arm B: Cisplatin at a dose of 75 mg/m\^2 IV or carboplatin AUC at a dose of 5 mg/mL/min IV Q3W
Primary outcome measures
Progression Free Survival by Blinded Independent Central Review
Time frame: From date of randomization to the date of radiographic disease progression or death due to any cause, up to approximately 54 months
PFS is defined as the time interval from the date of randomization to the date of radiographic disease progression or death due to any cause. Tumor response will be determined by BICR assessment of tumor scans using RECIST v1.1.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Sign and date the Tissue Screening ICF, prior to any Tissue Screening procedure. Sign and date the Main ICF, prior to the start of any trial-specific qualification procedures. Sign and date the Optional PGx ICF (included in the Main Screening ICF) prior to any PGx procedure, and the Pregnant Partner ICF, if applicable. 2. Adults ≥18 years of age on the day of signing the ICF. Follow local regulatory requirements if the legal age of consent for trial participation is \>18 years old. 3. Histologically documented non-squamous locally advanced unresectable or metastatic NSCLC and meets all of the following criteria: Has Stage IV NSCLC disease or Stage IIIB or IIIC disease but is not a candidate for surgical resection or definitive chemoradiation at the time of randomization (based on the American Joint Committee on Cancer, Eighth Edition). Has no known AGAs (based on existing test result of local test) that have locally available therapies targeting thei

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
