The purpose of this study is to determine the safety, tolerability, and preliminary efficacy of pembrolizumab/vibostolimab co-formulation (MK-7684A) with or without other anticancer therapies in participants with selected advanced solid tumors. The primary hypothesis is that pembrolizumab/vibostolimab co-formulation is superior to pembrolizumab alone in terms of objective response rate or progression-free survival in participants with cervical cancer.

Condition Uterine Cervical Neoplasms, Endometrial Neoplasms, Squamous Cell Carcinoma of Head and Neck, Gallbladder Neoplasms, Cholangiocarcinoma, Esophageal Neoplasms, Triple Negative Breast Neoplasms, Hepatocellular Carcinoma, Urinary Bladder Neoplasms, Ovarian Neoplasms, Stomach Neoplasms
Treatment Capecitabine, cisplatin, docetaxel, carboplatin, Gemcitabine, Paclitaxel, bevacizumab, Pembrolizumab, Oxaliplatin, 5-fluorouracil, Lenvatinib, Pembrolizumab/Vibostolimab Co-Formulation
