About this study

Official title: Recombinant Antihemophilic Factor (rAHF-PFM) Manufactured and Formulated Without Added Human or Animal Proteins: Evaluation of Pharmacokinetics, Immunogenicity, Efficacy and Safety in Previously Treated Pediatric Patients With Hemophilia A

The purpose of this study is to evaluate whether rAHF-PFM is effective and safe in the treatment of children with hemophilia A. The study consists of 2 parts. Part 1 of the study is a pharmacokinetic evaluation, and Part 2 is an evaluation of efficacy and safety.

What is being measured

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

  1. The terminal phase half-life of Recombinant Antihemophilic Factor (rAHF-PFM)

    Terminal phase half-life of rAHF-PFM was to be determined using the biphasic linear regression model.

    Measured: Within 30 minutes prior to the pharmacokinetic infusion and at 1 hour ± 5 minutes, 9 ± 1 hour, 24 ± 2 hours, and 48 ± 2 hours after the infusion

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Antihemophilic factor, recombinant, manufactured protein-free in people with Hemophilia A, run by Baxalta now part of Shire at 12 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 4 inclusion and 11 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 27 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, Canada, Puerto Rico. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The terminal phase half-life of Recombinant Antihemophilic Factor (rAHF-PFM) (time frame: Within 30 minutes prior to the pharmacokinetic infusion and at 1 hour ± 5 minutes, 9 ± 1 hour, 24 ± 2 hours, and 48 ± 2 hours after the infusion). 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 NCT00157040, which also lists 1 linked publication.

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 27 Apr 2021.
