Study groups in NCT01027377
Study groupRoleWhat they receive
AExperimentalCohort to receive a single low dose intravenous injection of commercially available rFVIII with safety and PK assessments followed by a single low dose intravenous injection of rFVIIIFc with safety and PK assessments
Receives: Drug: rFVIIIFc
BExperimentalCohort to receive a single high dose intravenous injection of commercially available rFVIII with safety and PK assessments followed by a single high dose intravenous injection of rFVIIIFc with safety and PK assessments
Receives: Drug: rFVIIIFc

What is being measured

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

  1. Safety will be assessed by physical examination, vital signs, laboratory changes overtime, adverse events, and assessment of inhibitor (Bethesda) and antibody development against rFVIIIFc.

    Measured: 78 weeks

Secondary outcomes (3)
  1. Pharmacokinetic parameters will be measured such as, but not limited to Tmax, Cmax, t1/2, CL, Vd, AUC, MRT, and incremental recovery.

    Measured: 78 weeks

  2. To determine the pharmacokinetics parameters after single administration of 25 and 65 IU/kg of rFVIIFc compared to advate

    Measured: 78 weeks

  3. To determine the pharmacodynamic activity of FVIII over time for both doses of rFVIIIFc

    Measured: 78 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing rFVIIIFc in people with Severe Hemophilia A, run by Bioverativ Therapeutics Inc. at 7 sites in 3 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 3 inclusion and 3 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 19 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States, Hong Kong, Israel. 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?

Safety will be assessed by physical examination, vital signs, laboratory changes overtime, adverse events, and assessment of inhibitor (Bethesda) and antibody development against rFVIIIFc. (time frame: 78 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01027377, which also lists 2 linked publications.

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 19 Dec 2020.
