SyB C-0501(Oral Bendamustine) in Patients With Advanced Solid Tumors

Phase 1
Completed
Conditions
Advanced Solid Tumor
Interventions
Drug: SyB C-0501
Registration Number
NCT03604679
Lead Sponsor
SymBio Pharmaceuticals
Brief 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.

GroupInterventionDescription
SyB C-0501SyB C-0501SyB C-0501 (Oral Bendamustine) will be administered orally once a day (specified dose). The treatment period of 21 days (Cohort 1; 7 days of administration + 14 days of observation or Cohort 2; 14 days of administration + 7 days of observation or Cohort 3; 21 days of administration) constitutes 1 cycle. Part 1: dose escalation to determine MTD, RD and dosing schedule Part 2: dose expansion at RD
Primary Outcome Measures
NameTimeMethod
Identification of Dose-Limiting Toxicity (DLT) and Number of Subjects with DLT in Each Cohort/LevelCycle 1 (Approximately 3 weeks)

Based on the number of patients with DLT and administration dose in each cohort, recommended dosage will be defined for the following clinical phase. A DLT is defined as an adverse event that occurred during the Cycle 1, for which a causality with the investigational products (IP) cannot be ruled out and meets the DLT criteria of this study.

Adverse Events (Types, Incidence, severity, Relationship to SyB C-0501)Approximately 2 years
Secondary Outcome Measures

Area under the concentration-time curve up to the last time point with detectable plasma concentration (AUC0-last) of unchanged bendamustine in plasmaDay 1, and Day 8 or Day 15 of Cycle 1 (each cycle is 21 days)
Area under the concentration-time curve up to infinity (AUC0-inf) of unchanged bendamustine in plasmaDay 1, and Day 8 or Day 15 of Cycle 1 (each cycle is 21 days)
