What is being measured

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

  1. The distribution of GP681 in the whole blood and plasma, and the radioactive pharmacokinetics following the single orally administered [14C]GP681 in healthy Chinese male volunteers.

    The percentage of radioactive dose of [14C] radiolabelled GP681 recovered in blood and in total.

    Measured: Up to 336 hours (approx) from the start of administration.

  2. Quantitive analysis of whole radioactivity of excrement of orally administered [14C]GP681 in healthy Chinese male subjects to obtain the mass balance data and the main excretion pathway in human body.

    The percentage of radioactive dose of [14C] radiolabelled GP681 recovered in urine, faeces and in total.

    Measured: Up to 432 hours (approx) from the start of administration.

  3. Quantitive analysis of the concentrations of GP681 and its major metabolites (such as GP1707D07) in plasma using the validated LC-MS/MS to obtain pharmacokinetic data.

    The concentrations of GP681 and its major metabolites in plasma.

    Measured: Up to 336 hours (approx) from the start of administration.

  4. Identification of the main metabolites and biotransformation pathway of GP681 following the single orally administered [14C]GP681 in healthy Chinese male volunteers

    Proportion of different metabolites.

    Measured: Up to 432 hours (approx) from the start of administration.

  5. Evaluation of safety following the single orally administered [14C]GP681 in healthy Chinese male volunteers.

    Adverse events assessed by NCI-CTCAE v5.0.

    Measured: Up to 432 hours (approx) from the start of administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C] GP681 in people with Healthy Volunteers, run by Jiangxi Qingfeng Pharmaceutical Co. Ltd. at 1 site in China.

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 6 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 10 Dec 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 China. 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?

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 distribution of GP681 in the whole blood and plasma, and the radioactive pharmacokinetics following the single orally administered [14C]GP681 in healthy Chinese male volunteers. (time frame: Up to 336 hours (approx) from the start of administration.). The study lists 5 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 Dec 2021.
