About this study

To evaluate the absorption, metabolism and excretion in healthy Chinese male subjects after a single oral dose of [14C]HSK39297

Read the detailed description
  1. To quantitatively analyze the total radioactivity in excreta after oral administration of [14C]HHSK39297 in healthy subjects, obtain the data on human radioactivity excretion rate and determine the main excretion pathways
  2. To quantitatively analyze the total radioactivity in whole blood and plasma in healthy subjects after oral administration of [14C]HSK39297, to obtain the pharmacokinetics of total radioactivity in plasma and to investigate the distribution of total radioactivity in whole blood and plasma
  3. To obtain the radioactive metabolite profile in plasma, urine, and feces after oral administration of [14C]HSK39297 in healthy subjects, to identify the main metabolites and to determine the metabolism and elimination pathways
Being tested
Carbon-14 labeled HSK39297
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Carbon-14 labeled HSK39297 in people with Paroxysmal Nocturnal Hemoglobinuria (PNH), run by Haisco Pharmaceutical Group 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 3 inclusion and 24 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 28 Feb 2025. 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?

Recovery of total radioactivity in urine and fecal samples (time frame: Up to 312 hours post dose). The study lists 3 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 28 Feb 2025.
