- and Taiwan (Patent No. I432191 and I282280). The R&D laboratory in TSB is ISO/IEC 17025 certified by Taiwan Accreditation Foundation (TAF) and the laboratory number is 2026.The trade name of TSB-9-W1 is "IDS" in English, the registration number is 01472800 at 2011 by Intellectual Property Office (IPO), Taiwan.
A phase I and pk study to determine the Maximum Tolerated Dose (MTD) and to evaluate the safety and efficacy profiles of TSB-9-W1 in pre-treated patients with metastatic colorectal cancer (mCRC).
there are 5 cohorts and a minimal 2 patients and up to 30 patients are required at phase I.
This is a single arm study. All eligible patients with mCRC will receive TSB-9-W1 treatment.
Each treatment cycle is composed by a contiguous 2-day oral administration and a contiguous 3-day rest. Patient should take the study drug once daily before meal with approximately 250 ml or appropriate amount of water.
详细描述
Study Design
This study is to establish the MTD of TSB-9-W1 for mCRC patients with a traditional 3+3 dose escalation method.
Study Structure
A dose escalation scenario is designed to determine the MTD according to the DLT.

结局指标
主要结局
Maximum Tolerated Dose (MTD)
时间窗: up to 3 years
DLT is to be observed during the first 6-treatment cycles (1 cycle = 5 days). If none of the first 3 patients experience DLT, then dose escalation will proceed for the next cohort of patients unless the present dose level is level 5 (1000 mg/day). If 1 of 3 patients develops DLT, the cohort will be expanded to 6 patients (another 3 patients to be added subsequently). If no more than 1 of the 6 patients experiences DLT, then escalation to the next dose level will proceed unless the present dose level is level 5. If more than 1 patient develops DLT in any dose cohort, the dose escalation will be withheld and the prior dose level is considered as the MTD unless present dose level is level 1 (200 mg/day).
Dose limiting toxicities (DLTs)
时间窗: 30 days
DLT (except diarrhea) is determined by (NCI-CTCAE) version 4.03 (2010/6/14) defined treatment related toxicity ≥ grade 3 and is worsen from the baseline. Any grade ≥ 3 toxicity (except for diarrhea) is considered a DLT unless there is a clear alternative explanation as to the attribution of the adverse event. Diarrhea event is considered as a DLT if the episode is with NCI-CTCAE Grade of 3 and this event lasts \> 3 days despite appropriate supportive cares or if it is a Grade 4 event. Diarrhea event reaches Grade 4 will trigger the patient to withdraw from the study. AEs are evaluated according to the NCI-CTCAE version 4.03 as determined by the investigator to be at least possibly related in causality to the IP administration.
