About this study

Official title: A Double-Blind, Placebo and Active Controlled, Single and Multiple Rising Dose, Safety, Tolerance, and Pharmacokinetic Study of TR-701 in Normal Healthy Adults

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single rising oral doses and multiple oral doses of TR-701

Read the detailed description

This is an evaluation of TR-701 in a double-blind, placebo-controlled, randomized, single (Part A) and multiple (Part B) ascending dose safety, tolerance, and PK when administered as a capsule in normal, healthy adult volunteers. The study will be sequential between Part A and Part B (i.e., not staggered or leap frogged), with slight overlap between last cohort in Part A and first cohort in Part B.

Being tested
TR-701, linezolid, placebo

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TR-701 and linezolid in people with Healthy Subjects, 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 8 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 31 Aug 2017. 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. Some participants in this study may receive a placebo. 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?

Adverse Event reporting (time frame: 21 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 NCT00671814, which also lists 2 linked publications.

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 31 Aug 2017.
