Congenital Coagulation Factor VII Deficiency

Study of the Pharmacokinetics and Safety of Recombinant Factor VIIa Fusion Protein (rVIIa-FP, CSL689) in Patients With Congenital Factor VII Deficiency

NCT02470871 | PHASE 1 | INTERVENTIONAL

The purpose of this study is to investigate the pharmacokinetics (PK) and safety of rVIIa-FP (CSL689) in a total of 10 to 16 male or female adults with inherited coagulation factor VII (FVII) deficiency. Subjects will receive a single dose of their routine FVII replacement product (ie, either recombinant activated coagulation FVII \[rFVIIa, eptacog alfa (activated)\] or plasma-derived FVII \[pdFVII\]) as a comparator, and will then be randomly assigned to a single low dose or a single high dose of the study product CSL689 (8 subjects per CSL689 dose level). Serial blood samples for PK analysis will be taken up to 24 hours after the eptacog alfa (activated) or pdFVII injection, and up to 48 hours after the CSL689 injection. Subject safety will be routinely monitored throughout the study.

Exclusion Criteria

* History of, or risk factors for, thromboembolic events, including known deep vein thrombosis.
* Inhibitor to FVII or rFVIIa, current or historic.
* Known or suspected hypersensitivity to hamster protein, to CSL689, or to any excipient of CSL689.
* Known or suspected allergy to rFVIIa or hamster protein.
* Major surgery within 1 month before screening.

* Human immunodeficiency virus (HIV)-positive subjects with cluster of differentiation 4 (CD4)+ lymphocyte count of \< 200/µL at screening.
* Use of an investigational agent within 30 days before the study.
* Use of concomitant therapy not permitted during the study (ie, other platelet inhibitors, desmopressin, fibrinolysis inhibitors, except if used as local treatment \[eg, for oral bleeds\])
