About this study

Official title: A Phase I Study to Determine and Compare Plasma, Epithelial Lining Fluid, and Alveolar Macrophage Concentrations of Intravenous ETX2514 and Sulbactam Administered to Healthy Adult Subjects

This is a Phase 1, multiple dose, open-label pharmacokinetic study conducted in healthy adult male and female subjects to determine and compare plasma, epithelial lining fluid (ELF) and alveolar macrophage (AM) concentrations of ETX2514 and sulbactam in healthy adult subjects after intravenous infusion of ETX2514 1.0 g given concurrently with intravenous sulbactam 1.0 g, administered every 6 hours with each infused over 3 hours, for 3 consecutive doses

Read the detailed description

Blood samples for determining plasma concentrations of ETX2514 and sulbactam will be collected within 5 minutes prior to and at 1.0, 2.0, 2.5, 2.95, 3.05, 3.25, 3.5, 4.0, 5.0 and 6.0 hours after start of the third dose (last dose) administered on Day 2.

Each subject will undergo one standardized bronchoscopy with bronchoalveolar lavage (BAL) in the outpatient bronchoscopy suite at 1.0, 2.5, 3.25, 4.0, or 6.0 hours after start of the infusion of the third dose of ETX2514 and sulbactam (6 subjects per timepoint) on Day 2.

Safety will be assessed throughout the study by adverse event monitoring, clinical laboratory tests, ECG, physical examination, and vital sign monitoring.

  1. Number of participants with any non serious adverse event (AE)

    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

  2. Number of participants with any serious adverse event (SAE)

    An SAE is defined as any event that results in death; is immediately life threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or is a congenital anomaly/birth defect.

    Measured: Day 1- 14

  3. Change from Baseline in electrocardiogram (ECG) parameters at the indicated time points

    Change in baseline is calculated as the post-baseline value minus the baseline value

    Measured: Day 1, 2, and 4

  4. Change from baseline in vital signs at the indicated time points

    change from baseline in calculated as the post baseline value minus the Baseline value

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ETX2514 and sulbactam in people with Healthy, run by Entasis Therapeutics 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 13 inclusion and 28 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 9 Nov 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. 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?

Mean maximum observed drug concentration (Cmax) in blood (time frame: Predose, 1,2,2,5, 2.95, 3.05, 3.25, 3.5, 4, 5, and 6 hours after the start of the third dose (last dose) on Day 2). The study lists 7 primary outcomes in all. 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 NCT03303924, 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 9 Nov 2017.
