Trial summary

MyPKFiT is a web-based application recently developed by Baxalta for the use in patients treated with Advate. MyPkFit has its basis in Bayesian forecasting, which allows estimation of individual PK parameters by a sparse sampling schedule, where only 2-3 samples are taken between 4 and 48 hours post infusion.

About this study

Official title: Optimizing the Use of Prophylaxis in Patients With Severe Haemophilia A Using PK Measurement (myPKFiT)

MyPKFiT is a web-based application recently developed by Baxalta for the use in patients treated with Advate. MyPkFit has its basis in Bayesian forecasting, which allows estimation of individual PK parameters by a sparse sampling schedule, where only 2-3 samples are taken between 4 and 48 hours post infusion. With myPKFiT, it will, therefore, be possible to define an individual PK curve for each patient based on just a few sampling points and hence, taking the bleeding phenotype and the life style into account, potentially adjust the prophylactic treatment accordingly to optimize cost-effectiveness.

Read the detailed description

As detailed in brief summary patients will, after accurate information verbally and written according to ethics approval, report bleeding events during previous 6 months. Blood samples are taken, FVIII analyzed (Advate patients) and the individual PK curve determined using MyPKFit. The curve will be discussed together with the patient and levels related to bleed events determined. If needed dose adjustment is done based on the curve. After a further 6 month follow-up bleeds will again be evaluated as well as factor consumption. In this way a better personalized treatment based on PK and clinical phenotype will hopefully be achieved.

What is being measured

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

  1. PK measurement to individualize replacement therapy

    To evaluate whether PK measurement by myPKFiT and the calculation of an individualized PK profile may allow the treating physician to personalize and optimize the treatment of patients with haemophilia A to minimize the number of bleeds in a cost-effective way without diminishing compliance.

    Measured: 3 years

  2. PK measurement to influence FVIII consumption

    1. To calculate whether optimization of treatment by use of MyPKFiT, as described in primary objective 1, result in change of total FVIII consumption and extra doses given before and after visit 1. Measurements are T1/2, area under the curve

    Measured: 3 years

  3. Specific pharmacokinetic parameters to analyze

    Biological half-life of infused FVIII product will be measured in hours. Area under the curve (AUC)will be given in IUxh/dL

    Measured: 3 years

Secondary outcomes (1)
  1. Signs of hemophilic arthropathy

    1. To identify and characterize and sign of arthropathy by ultrasound sound evaluation of the synovium, cartilage and bone according to the HEAD-US score of ankle, knee and elbows visit 1 and 2 and correlate this to the treatment provided.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Oktokog alpha in people with Hemophilia A, run by Lund University at 1 site in Sweden.

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 1 inclusion and 2 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 13 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 1 site in Sweden. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

PK measurement to individualize replacement therapy (time frame: 3 years). 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 13 Apr 2021.
