Brief summary
The purpose of this study is to evaluate the effect of the anti-programmed death 1 (PD-1) agent nivolumab following selective internal radiation therapy (SIRT) for patients with unresectable hepatocellular carcinoma (HCC). SIRT using yttrium90-loaded microspheres is increasingly used to treat patients with HCC, particularly those that are not good candidates for transarterial chemoembolization or TACE. SIRT induces disease control (objective tumor remission or stabilization) in most patients while progression usually results from the growth of new lesions. SIR-Spheres are resin-made microspheres used for SIRT. On the other hand, nivolumab is under clinical development for the treatment of more advanced HCC. Available data in patients that mostly had progression to other therapies and vascular involvement or metastatic disease show significant systemic antitumor activity that results in durable objective remissions and disease stabilizations. Therefore, in patients with HCC that has not spread beyond the liver, the systemic action of nivolumab may improve the anti-tumor effect of SIRT. Furthermore, by inducing immunogenic tumor cell death, SIRT may have a synergistic effect with nivolumab.
Detailed description
Worldwide, intra-arterial therapies are the mainstay of the treatment of patients with HCC in the intermediate stage or in the advanced stage because of portal vein invasion. While transarterial chemoembolization (TACE) is the most widely applied intra-arterial therapy, not all patients in the intermediate stage are good candidates for this procedure and TACE is formally contraindicated in the presence of portal vein invasion. Selective Internal Radiation Therapy (SIRT) using yttrium90-loaded microspheres is increasingly used to treat such patients that are not good candidates for TACE. SIR-Spheres are resin-made microspheres extensively used for SIRT and there is consistent level 2 evidence of its activity in HCC. SIRT induces disease control (partial objective remission or tumor stabilization) in the majority of patients while progression usually results from the growth of new lesions. Nivolumab is under clinical development for the treatment of advanced stage HCC. Preliminary data in a population that mostly had progression to other therapies, vascular involvement or metastatic disease suggest significant systemic antitumor activity that results in durable objective remissions and disease stabilizations. In patients with HCC that has not spread beyond the liver, the systemic action of nivolumab may improve the anti-tumor effect of SIRT by providing eradication or sustained tumor growth control of residual disease in treated lesions and other locations (intrahepatic or extrahepatic micrometastasis). Furthermore, by inducing immunogenic tumor cell death, SIRT may have a synergistic effect with immune checkpoint inhibitors including nivolumab. Besides, SIRT and nivolumab are by and large well tolerated. The sequential use of SIRT and nivolumab could have strong antitumor activity and a favorable safety profile and therefore deserves to be tested in patients with intermediate to advanced tumor stages. The primary objective of the study is therefore to evaluate the safety of nivolumab in combination with SIRT using SIR-Spheres. The secondary objective is to evaluate the anti-tumor activity of nivolumab in combination with SIRT using SIR-Spheres. Exploratory objectives are to evaluate the role of blood and tissue biomarkers in determining the anti-tumor activity of nivolumab in combination with SIRT using SIR-Spheres; to evaluate the utility of baseline or on-treatment soluble markers that may serve as surrogate markers of efficacy; and to explore the role of the ALBI score in predicting patient outcomes. SIRT will be performed as a single-day treatment using SIR-Spheres resin microspheres as detailed in Gil-Alzugaray et al. 2013. Three weeks after SIRT, patients will start receiving nivolumab every 2 weeks until completion of 8 courses of 3 bi-weekly nivolumab doses, toxicity, or tumor progression defined using RECIST 1.1 criteria. Patients will be allowed to continue nivolumab treatment beyond progression under strict protocol-defined circumstances. All subjects will undergo tumor assessments at every q6 week for the first year, and then q12 week thereafter until radiographic progression. Patients will complete a follow-up Visit 100 days from the last dose of nivolumab and will then be followed for overall survival. Patients with all etiologies could be recruited. Those with chronic hepatitis B will be on antiviral therapy per regional standard of care guidelines. Patients with chronic hepatitis C may receive treatment for this condition with direct antiviral agents during the treatment period as per local practice guidelines. A tumor sample obtained before SIRT and blood samples obtained before SIRT and before and after nivolumab will be used for correlative biomarker studies.
