Testing the Timing of Pembrolizumab Alone or With Chemotherapy as First Line Treatment and Maintenance in Non-small Cell Lung Cancer

Running, not enrolling · Phase 3

Conditions studied: Lung Non-Squamous Non-Small Cell Carcinoma, Stage IIIB Lung Cancer AJCC v8, Stage IIIC Lung Cancer AJCC v8, Stage IV Lung Cancer AJCC v8

In brief

This phase III trial studies whether pembrolizumab alone as a first-line treatment, followed by pemetrexed and carboplatin with or without pembrolizumab after disease progression is superior to induction with pembrolizumab, pemetrexed and carboplatin followed by pembrolizumab and pemetrexed maintenance in treating patients with stage IV non-squamous non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as pemetrexed, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. It is not yet known whether giving first-line pembrolizumab followed by pemetrexed and carboplatin with or without pembrolizumab works better in treating patients with non-squamous non-small cell cancer.

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must have histologically or cytologically confirmed stage IV non-squamous non-small cell lung cancer (NSCLC) (includes M1a, M1b, and M1c stage disease, American Joint Committee on Cancer [AJCC] 8th edition). Patients with stage IIIB and IIIC disease are eligible if they are not candidates for combined chemotherapy and radiation. Prior chemo-radiation therapy (RT) for stage III with recurrence is allowed
• Patients must have PD-L1 expression Tumor Proportion Score (TPS) >= 1% in tumor cells. If PD-L1 expression TPS is unevaluable or the testing could not be completed, the patients are not eligible. The assay must have been performed by a Clinical Laboratory Improvement Act (CLIA) (or equivalent) certified laboratory
• Patients must have measurable or non-measurable disease. The presence of malignant pleural fluid alone is sufficient to satisfy this eligibility criterion. Baseline imaging assessments and measurements used to evaluate all measurable or non-measurable sites of disease must be done within 4 weeks prior to study registration
• NOTE: If patient receives pemetrexed, follow institutional guidelines to drain fluids
• NOTE: An additional 15 days is allowed to account for any infection/exposure related logistical delays
• Patients must be >= 18 years of age
• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
• Patients must NOT have received the following:
• Prior systemic chemotherapy or immunotherapy for advanced metastatic NSCLC. Patients treated with any prior checkpoint inhibitors for metastatic lung cancer are ineligible. Chemotherapy for non-metastatic disease (e.g. adjuvant therapy) or immunotherapy for locally advanced stage III disease, or treated with neoadjuvant IO is allowed if at least 6 months have elapsed between the last dose of the prior therapy and study registration. Local therapy, e.g. palliative radiation, is allowed as long as a period of 14 days has passed between completion of local therapy and the start of protocol treatment. Registration during the 14 days is allowed. Palliative radiation must be to non-target lesions. Palliative radiation to pre-existing lesions while on protocol treatment is allowed as long as these areas have not grown to RECIST defined progression. Development of any new metastasis is considered progression. Concurrent radiation and protocol treatment is not allowed; protocol treatment may resume after completion of radiation as long as patient does not have greater than grade 2 side effects from radiation per physician discretion.
• Methotrexate (MTX) given in low doses for non-malignant conditions with last dose at least 14 days prior to date of registration will be allowed. Other low dose chemotherapeutics for non-malignant conditions will be considered, but review by the study chair is required
• Palliative radiation to non-target lesions (bone metastasis) is allowed if patient develops symptoms
• Patients with known EGFR mutations (except exon 20 insertion), BRAF mutations (V600) or ALK or ROS1 translocations or other driver mutations that can be treated with oral tyrosine kinase inhibitors are excluded
• Patients with treated brain metastases are eligible if follow-up brain imaging obtained at least 14 days after central nervous system (CNS)-directed therapy shows no evidence of progression. CNS progression counts as progression and patients must move on to the next phase after CNS treatment. Patients with asymptomatic new (at screening) or progressive brain metastases (active brain metastases at screening) are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy
• Patients are eligible if off steroids for at least 14 days prior to protocol treatment
• Anticonvulsants are allowed
• Patients with asymptomatic, sub-centimeter brain metastasis who at the discretion of investigators do not need immediate CNS directed therapies are eligible
• Patients with prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
• Patients must not have known pre-existing and clinically active interstitial lung disease, or a known history of (non infectious) pneumonitis that required steroids, or current pneumonitis
• Patients must not have significant gastrointestinal disorders with diarrhea as a major symptom (e.g., Crohn's disease, malabsorption, etc.)
• Patients must not have history of auto-immune condition (including Guillain-Barre Syndrome or Multiple Sclerosis) requiring ongoing or intermittent systemic treatment in the past 2 years prior to registration (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
• Patients must not have any other concomitant serious illness or organ system dysfunction that in the opinion of the investigator would either compromise patient safety or interfere with the evaluation of the safety of the study drug
• Patients must not receive any other investigational agents during the course of therapy
• Patients must not be pregnant or breast-feeding due to potential harm to the fetus or infant from cytotoxic chemotherapy and the unknown risk of pembrolizumab (MK-3475). All patients of childbearing potential must have a blood test or urine study within 72 hours prior to registration to rule out pregnancy. A patient of childbearing potential is someone, regardless of whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point; 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
• Patients must use accepted and effective method(s) of contraception or by abstaining from sexual intercourse from time of registration, while on study treatment, and continue for 120 days after the last dose of study treatment
