Detailed Description
This study is a randomized, placebo-controlled, multicenter research design to investigate the effectiveness and safety of a single-dose intravenous iron combined with HuEPO hematopoietic mobilization before surgery in patients undergoing unilateral total knee arthroplasty for the first time.
The study consists of a pilot trial and a formal trial. The pilot trial plans to enroll 20 subjects, with 10 subjects randomly assigned to the experimental group and 10 subjects to the control group. After the successful completion of the pilot trial, its safety and effectiveness, as determined by the investigators, hematologists, orthopedic surgeons, and statisticians, and the formal trial will be initiated. The relevant information and results will also be submitted to the ethics review committee. The formal trial plans to enroll 399 eligible subjects, with a random allocation ratio of 2:1 to the experimental group or the control group.
To ensure the safety of the subjects, the last subject in the pilot trial will be followed up for 21 days after surgery. The safety and effectiveness of the pilot trial results will be discussed by the investigators, hematologists, orthopedic surgeons, and statisticians before initiating the formal trial. The timing of medication, sample size, and visit points in the formal trial may be adjusted appropriately based on the results of the pilot trial.
