Pembrolizumab Plus Y90 Radioembolization in HCC Subjects

This is an open-label multi-center trial designed to evaluate the efficacy as well as the safety of combining pembrolizumab with Yttrium-90 (Y90) radioembolization in subjects with poor prognosis (high risk) HCC not eligible for liver transplant or surgical resection with well compensated liver function. Treatment will consist of pembrolizumab 200mg IV every 3 weeks in conjunction with Y90 radioembolization performed one week after the first dose of pembrolizumab. If bilobar disease is present, a second Y90 radioembolization will be performed no later than 4 weeks after the first procedure to the contralateral hepatic lobe.
