简要总结
Randomized double-blind placebo-controlled trial (RCT) study, to determine the impact of XCHT on irinotecan-induced severe delayed-onset diarrhea (SDOD), and to determine the feasibility of using plasma raloxifene-4'-glucuronide as a probe for intestinal UGT activity.
详细描述
A total of 98 patients, who are planning to recieve at least 3 cycles of irinotecan chemotherapy, will be randomly assigned, at a 1:1 ratio, to XCHT group or placebo group, using a central randomization system. Patients will be administered with XCHT/placebo (9 g, qd, po) for 5 days each cycle of chemotherapy for 3 cycles. The XCHT/placebo administration begins 3 days before chemotherapy in each cycle, that is the chemotherapy begins on the 4th day of XCHT/placebo administration. Plasma will be collected for pharmacokinetic testing (using raloxifene 60mg po as probe), on the day before chemotherapy, that is on the 3rd day of XCHT/placebo administration in each cycle. The purpose of this study includes 1) to determine the safety and efficacy of XCHT for prevention of irinotecan-induced diarrhea; 2) to determine the PK profile of SN-38, SN-38G, raloxifene, raloxifene-glucuronide, and XCHT components; and 3) to validate the use of raloxifene-4'G as a probe for irinotecan-induced diarrhea.

盲法说明
Patients will be randomly assigned to XCHT/placebo groups, at a 1:1 ratio, using a central randomization system provided by the TCM clinical study methodology group of Guangdong Provincial Hospital of Chinese Medicine. This group is also responsible for blinding, including keeping the blinding codes, supervision, and quality control of blinding, by allocating drug codes for each patient. Investigators will dispense the drug according to the drug codes. The investigators, the study subjects, the care givers, and the outcome assessors will be blinded to the assigned group of subjects.

研究组 & 干预措施
XCHT group
Patients will be administered with XCHT (9 g, qd, po) for 5 days each cycle of irinotecan chemotherapy for 3 cycles. The XCHT administration begins 3 days before chemotherapy in each cycle, that is the chemotherapy begins on the 4th day of XCHT administration. Plasma will be collected for pharmacokinetic testing (using raloxifene 60mg po as probe), on the day before chemotherapy, that is on the 3rd day of XCHT administration in each cycle.

Placebo group
Patients will be administered with placebo (9 g, qd, po) for 5 days each cycle of irinotecan chemotherapy for 3 cycles. The placebo administration begins 3 days before chemotherapy in each cycle, that is the chemotherapy begins on the 4th day of placebo administration. Plasma will be collected for pharmacokinetic testing (using raloxifene 60mg po as probe), on the day before chemotherapy, that is on the 3rd day of placebo administration in each cycle.
干预措施: Raloxifene (Other)
