Lung Cancer Clinical Trial
Study of Pembrolizumab/Vibostolimab (MK-7684A) in Combination With Concurrent Chemoradiotherapy Followed by Pembrolizumab/Vibostolimab Versus Concurrent Chemoradiotherapy Followed by Durvalumab in Participants With Stage III Non-small Cell Lung Cancer (MK-7684A-006/KEYVIBE-006)
This study is to evaluate the safety and efficacy of pembrolizumab/vibostolimab (MK-7684A) in combination with concurrent chemoradiotherapy (cCRT) followed by pembrolizumab/vibostolimab versus cCRT followed by durvalumab in participants with unresectable, locally advanced, stage III Non-small Cell Lung Cancer (NSCLC). The primary hypotheses are that pembrolizumab/vibostolimab with cCRT followed by pembrolizumab/vibostolimab is superior to cCRT followed by durvalumab with respect to the following:
progression free survival (PFS) per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR) in participants with programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥1% and PD-L1 all comer participants.
overall survival (OS) in participants with PD-L1 TPS ≥1% and PD-L1 all comer participants.
The main inclusion and exclusion criteria include but are not limited to the following:
Has pathologically (histologically or cytologically) confirmed diagnosis of NSCLC.
Has Stage IIIA, IIIB, or IIIC NSCLC by American Joint Committee on Cancer Version 8
Is determined to have unresectable, Stage III NSCLC as documented by a multidisciplinary tumor board or by the treating physician in consultation with a thoracic surgeon
Has no evidence of metastatic disease, indicating Stage IV NSCLC, in whole-body fluorodeoxyglucose (FDG)-positron emission tomography (PET) or FDG-PET/ computed tomography (CT) and CT or magnetic resonance imaging (MRI) scans of diagnostic quality of chest, abdomen, pelvis and brain
Has measurable disease as defined by RECIST 1.1, with at least 1 lesion being appropriate for selection as a target lesion, as determined by local site investigator/radiology review
Has not received prior treatment (chemotherapy, targeted therapy, or radiotherapy) for their Stage III NSCLC
Has provided tumor tissue sample (tissue biopsy [core, incisional, or excisional])
Has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 assessed within 7 days prior to the first administration of study intervention
Has a life expectancy of at least 6 months
Has small cell lung cancer (SCLC) or tumors with the presence of small cell elements. Mixed squamous/nonsquamous tumors are eligible
Has received prior radiotherapy to the thorax, including radiotherapy to the esophagus, mediastinum, or for breast cancer
Has received major surgery (with the exception of replacement of vascular access) within 4 weeks before randomization. If the participant had a major operation, the participant must have recovered adequately from the procedure and/or any complications from the operation before starting study intervention
Is expected to require any other form of antineoplastic therapy, while on study
Has received colony-stimulating factors (e.g., Granulocyte Colony-Stimulating Factor [G-CSF], Granulocyte Macrophage Colony-Stimulating Factor [GM-CSF], or recombinant erythropoietin) within 28 days prior to the first dose of study intervention
Has received a live or live-attenuated vaccine within 30 days before the first dose of study intervention
Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks before the first dose of study intervention
Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study medication
Has a known additional malignancy that is progressing or has required active treatment within the past 5 years
Has an active autoimmune disease that has required systemic treatment in past 2 years
Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease
Has an active infection requiring systemic therapy
Has a known history of human immunodeficiency virus (HIV) infection
Has a known history of Hepatitis B (defined as hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV ribonucleic acid [RNA] qualitative is detected) infection
Has had an allogenic tissue/solid organ transplant
Is unable to interrupt aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), other than an aspirin dose ≤1.3 grams per day, for at least 2 days (5 days for long-acting agents [for example, piroxicam]) before, during, and for at least 2 days after administration of pemetrexed
Is unable/unwilling to take folic acid, vitamin B12, and dexamethasone
