Popis
Inclusion criteria:1) Chinese male or female aged ≥18 years; 2) Requiring at least 12-week warfarin therapy as judged by clinicians; 3) Subjects with DVT/AF and a post-therapy target INR of 1.5-2.5; 4) Capable of providing written informed consent; 5) Capable of maintaining excellent communications with investigators and completing trial in accordance with trial stipulations.
Exclusion criteria:1) Subjects previously taking warfarin; 2) Known genotypes of CYP2C9 or/and VKORC1; 3) Subjects receiving or expecting to receive other therapies or other anticoagulants; 4) Subjects with contraindications for warfarin; 5) Subjects with severe cognitive dysfunctions; 6) Baseline INR ≥1.5; 7) Subjects with drug or alcohol dependence within the last 12 months; 8) Subjects receiving blood transfusion or bone marrow transplantation within the last 2 weeks; 9) Planning to receive invasive examinations (except for standard endoscopy) with a hemorrhagic tendency or undergoing surgery during trial.10) Prior to randomization, subjects receiving any trial drug or device within the last 3 months or planning to receive such an investigational therapy during trial; 11) Subjects with the following diagnoses or conditions: active malignant carcinomas (diagnosed within the last 5 years), but excluding adequately-treated non-melanoma skin cancer or other non-invasive or in situ cancer (e.g. cervical cancer in situ); anti-neoplastic therapy within the last 5 years (medication, radiotherapy or/and surgery); overt active disease or infection; life expectancy <6 months; 12)Other clinical reasons for unsuitable recruitment as judged by clinicians.

Experimentální: 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.

|
Aktivní komparátor: 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.
