About this study

Official title: A Phase 3 Randomized, Double-Blind, Multicenter Study Comparing the Efficacy and Safety of 6-Day Oral TR-701 Free Acid and 10-Day Oral Linezolid for the Treatment of Acute Bacterial Skin and Skin Structure Infections

This is a randomized, double-blind, double dummy, multicenter Phase 3 study of oral TR-701 FA 200 mg once daily for 6 days versus oral Zyvox® (linezolid) 600 mg every 12 hours for 10 days for the treatment of ABSSSI in adults.

Approximately 75 to 100 sites globally will participate in this study. Patients with an ABSSSI caused by suspected or documented gram positive pathogen(s) at baseline will be randomized 1:1 to study treatment

Read the detailed description

The primary objective is to determine the noninferiority in the early clinical response rate of 6 day oral TR-701 FA compared with that of 10-day oral linezolid treatment at the 48-72 Hour Visit in the ITT analysis set in patients with ABSSSI.

Being tested
TR-701 FA, Linezolid
Keywords

  • LinezolidDrug

    Also called Trade name = Zyvox, Generic name = linezolid

    Oral Linezolid 600 mg twice daily for 10 days

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Early Clinical Response Rate

    Responder: No increase in lesion surface area from baseline and oral temperature ≤37.6°C

    Measured: 48-72 hours

Secondary outcomes (7)
  1. Clinical Response at 48-72 Hours That is Sustained at the End of Therapy Visit.

    Responder: No increase in lesion surface area from baseline and oral temperature ≤37.6°C.

    Measured: Day 11

  2. Clinical Response at 48-72 Hours That is Sustained at the End of Therapy Visit in the Clinically Evaluable-End of Therapy Analysis Sets

    Responder: No increase in lesion surface area from baseline and oral temperature ≤37.6°C

    Measured: EOT Day 11

  3. Investigator's Assessment of Clinical Success at the Post Treatment Evaluation Visit

    Clinical success defined as resolution/near resolution of most disease-specific signs and symptoms, absence/near resolution of systemic signs of infection, if present at baseline, no new signs, symptoms, or complications attributable to the ABSSSIs so no further antibiotic therapy was required for the treatment of the primary lesion.

    Measured: Post-Treatment Evaluation (7-14 days after the End of Therapy)

  4. To Compare the Investigator's Assessment of Clinical Success at the Post Treatment Evaluation Visit in the Clinically Evaluable-Post Treatment Evaluation Analysis Set

    Clinical success defined as resolution/near resolution of most disease-specific signs and symptoms, absence/near resolution of systemic signs of infection, no new signs, symptoms, or complications attributable to the ABSSSIs so no further antibiotic therapy was required for the treatment of the primary lesion.

    Measured: Post-Treatment Evaluation (7-14 days after the End of Therapy)

  5. Investigator's Assessment of Clinical Response at the 48-72 Hour Visit

    Clinical improvement was defined as improvement in overall clinical status.

    Measured: 48-72 Hour Visit

  6. Investigator's Assessment of Clinical Response at the Day 7 Visit

    Clinical improvement was defined as improvement in overall clinical status.

    Measured: Day 7

  7. Change From Baseline in Patient-reported Pain, by Study Visit

    0=no pain, 10=worst pain Only 1 visit per participant for Day 4-6, only 1 visit for Day 7-9, and only 1 visit for Day 10-13.

    Measured: Multiple

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 2 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 29 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 84 sites in United States, Ukraine, Argentina, Canada, Czechia and 6 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Sep 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Early Clinical Response Rate (time frame: 48-72 hours). 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 NCT01170221, which also lists 7 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 29 Aug 2018.
