Brief summary

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.

Detailed description

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.

Interventions

XCHT 9g, po qd, 3 days before each cycle of chemotherapy for 5 days, for 3 cycles of chemotherapy.

DRUGPlacebo

Placebo 9g, po qd, 3 days before each cycle of chemotherapy for 5 days, for 3 cycles of chemotherapy.

DRUGIrinotecan regimen

Patients will receive 3 cycles of irinotecan chemotherapy. FOLFIRI regimen:irinotecan (180 mg/m2) intravenous (IV) for over 90 minutes on Day 1. Folinic acid (400 mg/m2) IV over 2 hours on Day 1. 5-fluorouracil (5-FU) IV bolus (400 mg/m2) over 5 minutes on Day 1, followed by 5-FU (2400 mg/m2) IV continuously for 46-48 hours. Every 2 weeks. mXELIRI regimen:irinotecan (200 mg/m2) intravenous (IV) for over 90 minutes on Day 1. Capecitabine (800 mg/m²) PO bid on day 1-14. Every 3 weeks. CapIRI regimen:irinotecan (180 mg/m2) intravenous (IV) for over 90 minutes on Day 1. Capecitabine (1000 mg/m²) PO bid on day 1-14. Every 3 weeks. FOLFOXIRI regimen:irinotecan (165 mg/m2) intravenous (IV) for over 90 minutes on Day 1. Oxaliplatin (85 mg/m2) intravenous (IV) for over 2 hours on Day 1.Folinic acid (400 mg/m2) IV over 2 hours on Day 1, followed by 5-FU (2400 - 3200 mg/m2) IV continuously for 48 hours. Every 2 weeks.

OTHERRaloxifene

Raloxifene 60mg po, used as probe for pharmacokinetic testing, on Day 3 (the day before chemotherapy), for 3 cycles of chemotherapy.

Masking description

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.
