About this study

Official title: An Exploratory Study to Evaluate the Dose Response-Relationship of Pharmacodynamic Parameters of AryoSeven, in Patients With Hemophilia With Inhibitors

Randomized, double-blind, single-dose, 5 ways crossover, exploratory clinical trial evaluating four different doses of AryoSeven (eptacog alfa, activated) and NovoSeven on selected pharmacodynamic parameters in patients with hemophilia with inhibitors.

Read the detailed description

Randomized, double-blind, single dose, 5 ways crossover, clinical trial evaluating four different doses (10 µg/kg, 30 µg/kg, 90 µg/kg, and 270 µg/kg) of AryoSeven (recombinant human FVII activated or eptacog alfa, activated) and one dose of NovoSeven (30 µg/kg) on selected pharmacodynamic parameters (PD) [Primary: Thrombin Generation Assay (TGA)] in male adult and adolescent (>12 years) patients with hemophilia A or B, with an inhibitors titer >5 Bethesda Units [BU] and not in bleeding status. This will be an exploratory study to evaluate dose-response relationship of PD markers as surrogate efficacy endpoints.

Being tested
Eptacog alfa, activated

What participants receive

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

  • Eptacog alfa, activatedBiological

    A dose sequence for each injection will be randomly selected from the following doses: 10 μg/kg, 30 μg/kg, 90 μg/kg, or 270 μg/kg, separated by a wash-out period of 3 days.

  2. Time to Peak (PD parameter)

    Time to Peak of thrombin generation curve (in minutes)

    Measured: Up to 30 hours after AryoSeven and NovoSeven injection

  3. Peak height (PD parameter)

    Peak height of thrombin generation curve (in nmol/ml)

    Measured: Up to 30 hours after AryoSeven and NovoSeven injection

  4. F1.2 prothrombin fragments (PD parameter)

    Peak height (micg/L)

    Measured: Up to 30 hours after AryoSeven and NovoSeven injection

  5. D-dimer (PD parameter)

    Peak height (micg/L)

    Measured: Up to 30 hours after AryoSeven and NovoSeven injection

  6. AUCinf (PK parameter)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Eptacog alfa, activated in people with Hemophilia A With Inhibitor and Hemophilia B With Inhibitor, run by AryoGen Pharmed Co. at 1 site in Iran.

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 5 inclusion and 12 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 10 Sep 2022. 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 Iran. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

Lag time of the thrombin generation curve (time frame: Up to 30 hours after AryoSeven and NovoSeven injection). 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 10 Sep 2022.
