Who may be able to join

  • Patients who meet all the following diagnostic and clinical criteria are eligible for the study:
  • Provide written informed consent prior to any study related procedures not part of normal medical care. Surrogate consent/use of a legally authorized representative may be provided, if permitted by local country and institution specific guidelines. If a patient regains consciousness while in the study and, per the Investigator's judgment, the patient is able to read, assess, understand, and make his/her own decision to participate in the trial, the patient can agree to continue participation and the patient should be re consented, if required by local country and institution specific guidelines.

  • Hospitalized for ≥ 48 hours, intubated (via endo or nasotracheal tube, including tracheostomy patients) and receiving mechanical ventilation for ≥ 48 hours at the time of randomization, and with acute changes made in the ventilator support system to enhance oxygenation, as determined by arterial blood gas, or worsening PaO2/FiO2 ratio.
  • All patients must have a chest radiograph or a lung CT scan within 48 hours prior to randomization showing the presence of new or progressive infiltrate(s) suggestive of bacterial pneumonia (based on Investigator's evaluation).
  • Clinical findings to support diagnosis of VABP. At least 1 of the following must be documented to be present within 24 hours prior to randomization:

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BV100 plus Polymyxin B and BAT in people with Ventilator Associated Pneumonia, run by BioVersys AG at 16 sites in 3 countries.

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 17 inclusion and 33 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 14 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in Georgia, Greece, Hungary. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 investigate the pharmacokinetic (PK) properties of BV100 co administered with Polymyxin B during 7 to 14 days of treatment in patients with ventilator associated bacterial pneumonia (VABP) (time frame: 14 days). The study lists 2 primary outcomes in all. 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 14 Jan 2025.
