What is being measured

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

  1. Cmax for Serum Deferiprone and Deferiprone 3-O-glucuronide

    Cmax was assessed over a 24-hour interval for analyses of deferiprone and its 3-O-glucuronide metabolite in subjects with normal hepatic function, mild hepatic impairment, or moderate hepatic impairment. Blood samples were obtained prior to dosing and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 9, 12, 16, and 24 hours post-dose.

    Measured: 24-hour interval

  2. Tmax for Serum Deferiprone and Deferiprone 3-O-glucuronide

    Tmax was assessed over a 24-hour interval for analyses of deferiprone and its 3-O-glucuronide metabolite in subjects with normal hepatic function, mild hepatic impairment, or moderate hepatic impairment. Blood samples were obtained prior to dosing and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 9, 12, 16, and 24 hours post-dose.

    Measured: 24-hour interval

  3. AUC0-∞ for Serum Deferiprone and Deferiprone 3-O-glucuronide

    AUC (area under the curve) from zero to infinity was assessed over a 24-hour interval for analyses of deferiprone and its 3-O-glucuronide metabolite in subjects with normal hepatic function, mild hepatic impairment, or moderate hepatic impairment. Blood samples were obtained prior to dosing and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 9, 12, 16, and 24 hours post-dose.

    Measured: 24-hour interval

  4. T1/2 for Serum Deferiprone and Deferiprone 3-O-glucuronide

    T1/2 was assessed over a 24-hour interval for analyses of deferiprone and its 3-O-glucuronide metabolite in subjects with normal hepatic function, mild hepatic impairment, or moderate hepatic impairment. Blood samples were obtained prior to dosing and at 0.25, 0.50, 0.75, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 9, 12, 16, and 24 hours post-dose.

    Measured: 24-hour interval

  5. CumAe for Urine Deferiprone and Deferiprone 3-O-glucuronide

    Cumulative amount of deferiprone and deferiprone 3-O-glucuronide excreted in the urine. Urine samples were collected at the intervals of -2 to 0 hours pre-dose, and 0-2, 2-4, 4-8, 8-12 ,and 12- 24 hours post-dose.

    Note: For unknown reasons, the urine samples for one subject in the moderate hepatic failure group had low or zero volume and there were no measurable levels of deferiprone or its metabolite in any of the samples. Accordingly, the urine PK results were derived both with and without this subject's data, and are here presented without them (i.e., N=6 rather than 7).

    Measured: 24-hour interval

  6. Fe% for Urine Deferiprone and Deferiprone 3-O-glucuronide

    Cumulative fraction of Ferriprox dose excreted in urine as deferiprone or deferiprone 3-O-glucuronide. Urine samples were collected at the intervals of -2 to 0 hours pre-dose, and 0-2, 2-4, 4-8, 8-12 ,and 12- 24 hours post-dose.

    Note: For unknown reasons, the urine samples for one subject in the moderate hepatic failure group had low or zero volume and there were no measurable levels of deferiprone or its metabolite in any of the samples. Accordingly, the urine PK results were derived both with and without this subject's data, and are here presented without them (i.e., N=6 rather than 7).

    Measured: 24-hour interval

Secondary outcomes (1)
  1. Safety and Tolerability of Ferriprox in Subjects With or Without Hepatic Impairment.

    The number of participants who experienced adverse events following a single dose of Ferriprox, between the time of dosing and the follow-up visit (including any changes of clinical significance in physical examinations, vital signs, 12-lead ECG, and clinical laboratory tests).

    Measured: Time of dosing until 48 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ferriprox® in people with Hepatic Impairment, run by ApoPharma at 2 sites in United States.

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

Who may be eligible to take part?

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 2014. 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 United States. 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?

Yes. Results are posted in the registry (first posted 10 Sep 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Cmax for Serum Deferiprone and Deferiprone 3-O-glucuronide (time frame: 24-hour interval). The study lists 6 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 10 Sep 2014.
