  • History of Gilbert's Syndrome
  • History of any allergy that, in the opinion of the Investigator, contraindicates participation in the trial.

About this study

Official title: An Open-Label Mass Balance Study to Investigate the Pharmacokinetics, Excretion, and Recovery of Single-Dose Oral [14C]-Rodatristat Ethyl in Healthy Male Subjects

This is an open-label study to evaluate the PK and excretion of a single oral dose of [14C]-rodatristat ethyl. The study will consist of: Screening evaluations (within 29 days prior to dosing); a treatment phase (from dosing until discharge from the unit, a minimum of 7 days and a maximum of 14 days); and discharge procedures.

Read the detailed description

This is an open-label study to evaluate the PK and excretion of a single oral dose of [14C]-rodatristat ethyl. The study will consist of: Screening evaluations (within 29 days prior to dosing); a treatment phase (from dosing until discharge from the unit, a minimum of 7 days and a maximum of 14 days); and discharge procedures.

After meeting eligibility criteria, approximately 6 healthy male subjects will check into the clinical unit (Day -1), and the following morning, receive a single oral suspension of rodatristat ethyl 600 mg containing a mixture of [12C]-rodatristat ethyl and [14C]-rodatristat ethyl to contain approximately 600 microcuries (μCi) of radioactivity (Day 1). After fasting 10 hours overnight, the dose will be administered with a standard-calorie meal. Following dosing, serial whole blood and plasma PK samples, and urine and feces will be collected until discharge. Subjects will stay in the clinic until at least Day 7. Subjects will be discharged if total recovery (urine and feces combined) of the administered radioactive dose is ≥90% and the total daily recovery of radioactive dose is ≤1% on 2 consecutive days in which a fecal sample is collected. If not, subjects will remain in the clinic until these criteria are met but not longer than 15 days (which includes Day -1). Plasma and urine samples will be analyzed for total radioactivity, rodatristat ethyl, rodatristat, M15, and any other identified metabolites (if applicable). Blood and fecal samples will be analyzed for total radioactivity, rodatristat ethyl, rodatristat, and metabolite(s).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Radio-labeled rodatristat ethyl 600 mg in people with Healthy, run by Altavant Sciences GmbH at 1 site in United States.

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 25 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 13 Jul 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 United States. 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?

Overall, urinary, and fecal recovery of total radioactivity as a percentage of administered dose. (time frame: 15 days or until total recovery (urine and feces combined) of the administered radioactive dose is ≥90% and the total daily recovery of radioactive dose is ≤1% on 2 consecutive days in which a fecal sample is collected). 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 13 Jul 2022.
