Genotype-guided Warfarin Individualized Treatment
1. november 2017 opdateret af: The Third Xiangya Hospital of Central South University
Pharmacogenetic Algorithm of Response to Warfarin During Initial Anticoagulation in Chinese Elderly Patients
The purpose of this study is to determine whether the international pharmacogenetic algorithm is better than the standard initiation dosing and whether the two algorithms are suitable for Chinese elderly patients.

Detaljeret beskrivelse
The study protocol is a multicenter, randomized, patient-blinded and controlled trial, comparing two approaches among 864 enrolled AF(atrial fibrillation) or DVT(deep venous thrombosis) patients for guiding warfarin initial anticoagulation in Chinese elderly patients: the intervention group using the algorithm of International Warfarin Pharmacogenetic Consortium and its dose revision, and the control group using a standard initiation dose (2.25 mg).The study hypothesis is that the intervention group relative to the control group will increase the percentage of time in therapeutic INR (international normalized ratio) range during the first 3 months.This trial is the first prospective large-scale randomized controlled trial for elders in China.
It is of great significance for promoting special crowd individualization of anticoagulants at home and abroad.

|
Eksperimentel: genotype-guided group
Interventions：on day1~day3, patients received dose according to IWPC formula (PGx-1) included clinical variables and genotype data for VKORC1, CYP2C9*1, CYP2C9*2, and CYP2C9*3; on day4~day7, patients received dose according to Lenzini formula consisted of clinical variables, VKORC1, CYP2C9*2, CYP2C9*3 and previous INR and dosing information (PGx-2); and on day8, the clinicians adjusted the dose according to observed INR.The overall follow-up period is 12 weeks.
|
Intervention：initial dosing of warfarin for the first 3 days of treatment will be determined by IWPC( International Warfarin Pharmacogenetics Consortium) algorithm (PG-1),a second dose adjustment will be made after 3 doses of warfarin using a dose revision algorithm (PG-2) that combined INR values,the dose will be adjusted depending on the measurements of INR values after 7 days.The overall follow-up period is 12 weeks.

Aktiv komparator: control group
Interventions：on day1~day3, patients were given initial dose (2.25mg); and starting from day4, the clinicians began to adjust the dose for patients according to observed INR.The overall follow-up period is 12 weeks.

Intervention：initial dosing of warfarin for the first 3 days of treatment will be determined by standard initiation dose.
Following this initiation dose of warfarin,the dose will be adjusted depending on the measurements of INR values after 3 days.The overall follow-up period is 12 weeks.
