Summary
An open-label, single dose pharmacokinetic study of Xyntha (Moroctocog Alfa (AF-CC), Recombinant Factor VIII) in male Chinese subjects with hemophilia A
Eligibility Criteria
Inclusion Criteria
Subjects must meet all of the following inclusion criteria to be eligible for enrollment in the study:
- Male Chinese subjects 6 years or older (weight >20 kg) with severe hemophilia A (factor VIII activity 150 exposure days to any FVIII-containing products.
- Subjects should not have received an infusion of any FVIII products for at least 3 days (at least 72 hours) before the administration of Xyntha on Day 1.
- Subjects must be in a non bleeding state before the administration of Xyntha on Day 1.
- Evidence of a personally or legally acceptable representative (legally acceptable representative is only applicable to pediatric subjects) signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
- Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
Exclusion Criteria
Subjects with any of the following characteristics/conditions will not be included in the study:
- Current FVIII inhibitor or history of FVIII inhibitor (defined as > upper limit of normal (ULN) of the local reporting laboratory).
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or clinical findings at Screening.
- Diagnosed with any other bleeding disorder in addition to hemophilia A.
- Documented Human Immunodeficiency Virus (HIV).
- Subjects anticipating elective surgery or other invasive procedure within 1 month following study entry.
- Treatment with immunomodulatory therapy within 30 days or 5 half lives whichever is longer, prior to study entry or planned use for the duration of study participation.
- Subjects with known hypersensitivity to the active substance or to any of the excipients of Xyntha.
- Subjects with a known hypersensitivity to Chinese Hamster Ovary cell (CHO cell) proteins.
- Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study specific laboratory and confirmed by a single repeat, if deemed necessary: significant hepatic or renal impairment (alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >3 x ULN, or total bilirubin >2 x ULN or serum creatinine >2 x ULN), prothrombin time >1.5 x ULN, platelet count 450 or a QRS interval >120 msec msec. If QTcF exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTcF values should be used to determine the subject's eligibility.
- Blood donation (excluding plasma donations) of approximately 500 mL or more within 56 days prior to dosing.
- History of sensitivity to heparin or heparin induced thrombocytopenia.
- Unwilling or unable to comply with the Lifestyle Guidelines described in this protocol.
- Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the Investigator, or subjects who are Pfizer employees directly involved in the conduct of the study.
- Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
- Subjects with history of infection within 1 week prior to study entry.
- Male subjects with partners currently pregnant and male subjects able to father children who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after
