  • To identify the chemical structure of each metabolite with an exposure (AUC) of more than 10% of circulating total radioactivity
  • To explore the intravenous (IV) pharmacokinetics (PK) of [14C]-SK-1404

  • To provide additional safety and tolerability information for SK-1404
Read the detailed description

This is a single-centre, 2-part, open-label, non-randomised, sequential, single dose study in healthy male subjects. It is planned to enrol a single cohort of 6 healthy male subjects who will participate in Parts 1 and Part 2 of the study.

In Part 1, each subject will receive a single PO dose of SK-1404 followed by an IV microtracer dose of [14C]-SK-1404.

In Part 2, each subject will receive a single PO dose of [14C]-SK-1404.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C]-SK-1404 in people with Nocturia, run by Sanwa Kagaku Kenkyusho Co., Ltd. at 1 site in United Kingdom.

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 7 inclusion and 14 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 14 Oct 2016. 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 United Kingdom. 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?

Absolute bioavailability (F) calculated with the AUC values of IV administration in Part 1 and PO administration in Part 2 (time frame: Predose to 96hr). 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 14 Oct 2016.
