This is an investigator initiated , single-arm, open-label study of RT-01 as a single agent given via Intravenous injection（IV）with or without Intratumoral injection（IT） in combination with IV Nivolumab in patients with advanced solid tumors.~This study is planned to enroll 40-50 patients with advanced solid tumors. RT-01 will be administered as a single dose on day 1, Nivolumab will be administered intravenously every 3 weeks starting on day 5.~The purpose of this study is to assess the safety and tolerability, antitumor activity, The immunoreactivity, The immunogenicity, pharmacokinetics and virus shedding of RT-01 in combination with PD-1 Inhibitor (Nivolumab).
