About this study

Official title: An Open-Label, Randomized, Single-Dose, 2-Treatment, 2-Sequence, Crossover, Exploratory Pharmacokinetic and Bioavailability Study of 2 Capsule Formulations of TR-701 (Torezolid Phosphate) in Normal Healthy Adults

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of 2 different TR-701 oral formulations (free acid phosphate powder in capsule and di-sodium phosphate salt formulated capsule) after single doses in normal healthy adult subjects and to assess the relative bioavailability of TR-701 free acid phosphate powder in capsule formulation compared to di-sodium phosphate salt formulated capsule.

Read the detailed description

Subjects will receive the following treatments in a crossover design:

Treatment A (Reference): One 200 mg capsule of TR-701 di-sodium phosphate salt (equivalent to 150 mg TR-700) administered orally after at least an 8-hour fast with 240 mL room temperature water;

Treatment B (Test): One 182 mg capsule of TR-701 free acid phosphate (equivalent to 150 mg TR-700) administered orally after at least an 8-hour fast with 240 mL room temperature water;

Descriptive statistics will be calculated for PK parameters including Cmax, Tmax, AUC0-t, and AUC0-inf.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TR-701 di-sodium phosphate salt and TR-701 free acid phosphate in people with Healthy, run by Trius Therapeutics LLC, a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA) 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 3 inclusion and 3 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 3 May 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 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?

To evaluate the pharmacokinetics and relative bioavailability of TR-701 free acid phosphate powder in capsule formulation compared to di-sodium phosphate salt formulated capsule after single doses in normal healthy adult subjects (time frame: 4 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00876655, which also lists 1 linked publication.

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 3 May 2016.
