About this study

Official title: A Human Mass Balance Study of Pyronaridine Using Accelerator Mass Spectrometry

The combination of pyronaridine and artesunate is an antimalarial therapy in development. This mass balance study is intended to determine the rate and extent of excretion of total radioactivity in urine and feces following administration of a single oral micro-dose of 14C-pyronaridine in humans.

Read the detailed description

This is a monocenter, open-label, non-placebo-controlled, single-group, single-dose study. Six male subjects will receive a single dose of Pyronaridine 720 mg orally administered together with 14C-Pyronaridine (approx. 100 µg, 800 nCi (29600 Bq)).

Safety measurements (12-lead ECG, vital signs, blood chemistry and haematology) and adverse events will be monitored throughout the study. Subjects will come to the clinic the evening before the dosing of Pyronaridine. After the drug intake at day 1, subjects will have regular in-house periods for specimen collection up to 87 days after the drug administration. Blood, feces and urine will be collected during the hospitalisation periods. Samples will be analyzed for radioactivity by Accelerator Mass Spectrometry (AMS).

What is being measured

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

  1. Analysis of 14C-Pyronaridine Total Radioactivity in Urine

    Radioactivity recovery in urine as a percent of the administered dose.

    Continuous collection of samples was performed through 168 hours post-dose, with intermittent 48 hour collections occurring thereafter

    Measured: 2064 hours

  2. Analysis of 14C-Pyronaridine Total Radioactivity in Feces

    Radioactivity recovery in feces as a percent of the administered dose.

    Continuous collection of samples was performed through 168 hours post-dose, with intermittent 48 hour collections occurring thereafter

    Measured: 2064 hours

Secondary outcomes (3)
  1. Total Radioactivity in Blood: AUC0-t, AUC0-∞

    Pharmacokinetic Parameters:

    AUC0-t: area under the plasma concentration-time curve from Hour 0 through the last quantifiable concentration time (LQCT), where LQCT is the time at which the last sample with a quantifiable concentration was collected AUC0-∞: area under the plasma concentration-time curve from Hour 0 to infinity

    PK sampling performed at predose, 0.5, 1, 2, 4, 8, 12 and 24 hours, and 2, 4, 6, 7, 14, 21, 28, 35 and 42 days post-dose

    Measured: 42 days

  2. Total Radioactivity in Blood: Cmax

    Pharmacokinetic Parameters:

    Cmax: maximum observed peak observed concentration

    PK sampling performed at predose, 0.5, 1, 2, 4, 8, 12 and 24 hours, and 2, 4, 6, 7, 14, 21, 28, 35 and 42 days post-dose

    Measured: 42 days

  3. Total Radioactivity in Blood: Half-life, Tmax

    Pharmacokinetic Parameters:

    Half-life: computed as ln (2) / Kel Tmax: time to maximum concentration

    PK sampling performed at predose, 0.5, 1, 2, 4, 8, 12 and 24 hours, and 2, 4, 6, 7, 14, 21, 28, 35 and 42 days post-dose

    Measured: 42 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 14C-labeled Pyronaridine in people with Malaria, run by Medicines for Malaria Venture at 1 site in Switzerland.

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 14 inclusion and 15 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 26 Jan 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 Switzerland. 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?

Yes. Results are posted in the registry (first posted 26 Jan 2022). 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?

Analysis of 14C-Pyronaridine Total Radioactivity in Urine (time frame: 2064 hours). The study lists 2 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 26 Jan 2022.
