Efficacy and Safety of AlphaNine Versus BeneFIX in Patients With Severe Hereditary Haemophilia B
Efficacy and Safety of Factor IX (FIX) Contained in AlphaNine® and Its Pharmacokinetic Comparison With BeneFIX® in Patients With Severe Hereditary Haemophilia B
Study Overview
Detailed Description
Two pharmacokinetic assessments (studies) were carried out in the same subjects during a previous clinical trial. The first pharmacokinetic study (PK1) was performed after a single dose of AlphaNine. The second pharmacokinetic study (PK2) was performed following 26 Weeks of AlphaNine treatment after PK1. To compare AlphaNine with BeneFIX, a third pharmacokinetic study (PK3) (current study) was performed after a single dose of BeneFIX administered following a 7- to 15-day wash-out period.
The main objective of the PK3 study was to assess the pharmacokinetic profile of BeneFIX and compare to the pharmacokinetic profile of AlphaNine from the PK2 study.

Description
Key Inclusion Criteria:
- Participated in the previous study "Efficacy and safety of factor IX (FIX) contained in Alphananine in patients with severe hereditary haemophilia B":
- Congenital deficiency in Factor IX (FIX)
- FIX residual activity of ≤2% of normal
- Had required FIX-containing products in the past and in clinical records that were collected data to assess a reliable estimation of at least 150 treatment exposure days to previous products
- Was able to receive treatment for more than 10 days for a 6-month period
Key Exclusion Criteria:
- Received a dose of FIX in the 7 days prior to the infusion
- FIX inhibitor level of >0.5 Bethesda units (BU) or clinically relevant presence in the past (≥5 BU)

- Had a known allergic reaction to any BeneFIX component
- Exhibited symptoms of any intercurrent infection (ie, fever, chills, nausea) at the time of the first infusion
- Had any disease that might affect the distribution or metabolism of FIX and which could affect interpretation of the study (such as non-controlled diabetes mellitus)
- Had non-controlled arterial hypertension
- Had abnormal renal function (creatinine >1.5 mg/dL)
- Had documented liver cirrhosis or any hepatic disorder with alanine aminotransferase (ALT) levels 2.5x upper limit of normal (ULN )
- Prevision to be concomitantly treated with other FIX-containing products
- Had conditions that might affect subject compliance (survival-limiting [in 2 year time] diseases, alcohol or other drug abuse, etc.)
- Unable to provide a storage plasma sample before the first dose of BeneFIX
