About this study

Official title: Multi-center, Randomized, Open-label, Parallel-Arm, Single-dose, Pharmacokinetic Study of rVIIa-FP (CSL689) in Subjects With Congenital Factor VII Deficiency

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.

Being tested
Eptacog alfa (activated) or pdFVII, CSL689

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Eptacog alfa (activated) or pdFVIIBiological

    Comparator Drug 1: Recombinant activated FVII (rFVIIa). Subjects with eptacog alfa (activated) as their routine FVII replacement therapy will receive a single dose of eptacog alfa (activated) in the study.

    Comparator Drug 2: Plasma-derived FVII (pdFVII). Subjects with pdFVII as their routine FVII replacement therapy will receive a single injection of pdFVII in the study.

  • CSL689Biological

    Experimental Drug: Recombinant fusion protein, linking activated FVII with albumin (rVIIa-FP). Subjects will receive a single dose of CSL689 at either a low dose (Arm 1) or a high dose (Arm 2)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Terminal half-life of plasma FVIIa activity

    Measured: Up to 48 hours after CSL689 injection

  2. Maximum observed plasma FVIIa activity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  3. Area under the curve (AUC0-t)

    Area under plasma FVIIa activity versus time curve from time 0 to last sample with quantifiable activity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

Secondary outcomes (7)
  1. Total clearance

    Total clearance of plasma FVIIa activity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  2. Volume of distribution of the terminal phase

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  3. AUC(0-inf)

    Area under plasma FVIIa activity versus time curve from time 0 extrapolated to infinity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  4. Incremental recovery

    Incremental recovery of plasma FVIIa activity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  5. Time of occurrence of maximum observed plasma FVIIa activity

    Measured: Before injection and at up to 9 time points until 48 hours after injection

  6. Number of subjects with antibodies against Chinese hamster ovary protein and FVII

    Measured: Up to 30 days after CSL689 injection

  7. Number of subjects with inhibitors against FVII

    Measured: Up to 30 days after CSL689 injection

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Eptacog alfa (activated) or pdFVII and CSL689 in people with Congenital Coagulation Factor VII Deficiency, run by CSL Behring at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands, Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Terminal half-life of plasma FVIIa activity (time frame: Up to 48 hours after CSL689 injection). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2017.
