About this study

Official title: A Study to Evaluate the Mass Balance and Absolute Bioavailability of [14C]JMKX003142 in Healthy Male Participants

A phase 1 healthy volunteer study to assess the excretion and metabolism as well as the absolute bioavailability of oral JMKX003142. The study will be conducted in two parts: Part 1 to assess the mass balance of JMKX003142 using orally administered radiolabelled JMKX003142; part 2 will assess the absolute bioavailability using JMKX003142 and radiolabelled JMKX003142 as intravenous and oral forms

Being tested
[14C]JMKX003142, JMKX003142 tablets, [14C]JMKX003142 solution for infusion

What is being measured

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

  1. Mass balance of JMKX003142

    Total recovery of radioactivity in urine and faeces following a single oral dose of [14C]-JMKX003142 (expressed as a percentage of the total radioactive dose administered)

    Measured: up to 15 days (until >90% of dose is recovered)

  2. Absolute bioavailability of JMKX003142 in plasma

    Absolute bioavailability is calculated from the AUCs of iv and oral administration

    Measured: 96 hours

Secondary outcomes (5)
  1. Part1: Maximum Concentration (Cmax) of JMKX003142 in Plasma

    Measured: Day 1 to day 15 (depending on recovery of dose)

  2. Part1: Time to Reach Maximum Concentration (tmax) of JMKX003142 in Plasma

    Measured: Day 1 to day 15 (depending on recovery of dose)

  3. Part1: Apparent Terminal Half-Life (t1/2) Of JMKX003142

    Measured: Day 1 to day 15 (depending on recovery of dose)

  4. Part1: Area Under the Concentration-Time Curve from Time Zero Extrapolated to Infinity (AUC0-inf) of JMKX003142 in Plasma

    Measured: Day 1 to day 15 (depending on recovery of dose)

  5. Frequency and severity of Participants With Adverse Events (AEs)

    Measured: Up to Day 30

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C]JMKX003142, JMKX003142 tablets and [14C]JMKX003142 solution for infusion in people with ADPKD (Autosomal Dominant Polycystic Kidney Disease), run by Jemincare.

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 3 inclusion and 5 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: opening soon, as of the sponsor's last update on 10 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

This study is still under way. Results are not available in the source record yet.

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?

Mass balance of JMKX003142 (time frame: up to 15 days (until >90% of dose is recovered)). 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 10 Mar 2026.
