入选标准
- •(1) Patients who have provided written informed consent (For patients under18 years of age, legally acceptable representatives have provided written informed consent)
- •(2) Patients with congenital factor X deficiency who require routine prophylaxis and/or on-demand treatment to control bleeding episodes/perioperative management of bleeding
- •(3) [Routine prophylaxis cohort] Patients receiving routine treatments with fresh frozen plasma (FFP), prothrombin complex concentrate (PPC), etc. to control the bleeding tendency
- •(4) [On-demand treatment cohort] Patients who experienced bleeding or excessive menstruation which required treatments with FFPs, PCC, etc. to control bleeding episodes at least once within six months before screening
排除标准
- •(1) Patients with inhibitors to human blood-coagulation factor X (FX) or with a history of detectable FX inhibitors (>0.6 BU/mL)
- •(2) Patients with known or suspected coagulation/fibrinolysis defects other than the target disease in this study
- •(3) Patients with a history of disseminated intravascular coagulation or thrombus/embolism
- •(4) Patients with known or suspected hypercoagulation
- •(5) Patients with thrombocytopenia
- •(6) Patients with severe liver disorder or renal disorder
- •Patients undergoing treatments for severe liver disorder (AST and/or ALT: more than five times the maximum limit in the reference range), hepatic cirrhosis, or hepatic cancer
- •Patients with severe renal disorder (serum creatinine: more than three times the maximum limit in the reference range)
- •(7) Patients with a severe disease such as a malignant tumor or leukemia which requires or may require chemotherapy or radiotherapy during the study
- •(8) Patients with a history of shock or hypersensitivity to therapeutic proteins including blood products
- •(9) Patients with a history of surgical procedures and who have not completely recovered
- •(10) Patients with disorders or symptoms which investigators considered to disrupt study participation, pose risks to patients or have confounding effects on study observations
- •(11) Patients who had participated in a clinical trial and received other investigational drugs/investigational devices within 30 days before screening or who plan to participate in other clinical trials and receive other investigational drugs/investigational devices during this study
- •(12) Breastfeeding women, pregnant women, women/men planning to have a child, women of childbearing potential who experience menstruation and are premenopausal with no intention to use effective contraceptive devices during this study, and men who are not willing to use effective contraceptive devices during this study
