Primary: -To evaluate the safety and tolerability of S-531011 and to determine the MTD and/or RP2D of S-531011. Secondary: - To evaluate the preliminary antitumor activity of S-531011 per RECIST version 1.1a. - To characterize the PK profile of S-531011. -To evaluate the host immune response (immunogenicity) to S-531011. -To evaluate serum tumor-specific markers. Exploratory: -To explore the potential pharmacodynamic markers and proof of mechanism of S-531011 in tumor tissues. -To explore the potential pharmacodynamic markers of S-531011 in PBMCs and plasma. -To explore the potential biomarkers associated with S-531011 clinical activity.
