• Status: Completed
• Trial end date: 2020-09-11
• Target enrollment: 0
• Participant gender: All

Summary

This study is an open-label, multicenter, phase 1 study of SyB C-0501 by continuous daily oral administration in patients with advanced solid tumors, who have previously received anticancer therapy and consists of two parts. Part 1 is a dose escalation study to evaluate tolerability of SyB C-0501 in the patients, and to find the maximum tolerated dose (MTD), recommended dose (RD) and optimum dosing schedule. Part 2 is being done to evaluate safety and anti-tumor activity of SyB C-0501 preliminarily at RD, and to assess its target cancer exploratory.

• Phase: Phase 1
