About this study
Official title: A Pilot Proof of Concept Single-Center Study of the Use of Oritavancin in Systemic Staphylococcus Aureus Infections in Patients With Opioid Use Disorder
This will be a pilot single-arm study consisting of 15 participants evaluating the use of oritavancin in the final consolidation phase (last two weeks of treatment) of systemic infections with Staphylococcus aureus (S. aureus) in opioid users.
The purpose of this pilot proposal is to collect information for a subsequent large, randomized intervention. Primary endpoints will be 1) Safety and tolerability, and 2) Duration of hospitalization and rate of recurrence.
Read the detailed description
This will be an early phase, single center, open label pilot study of 15 participants designed to evaluate the effects of oritavancin in patients with Opioid Use Disorder and/or Intravenous Drug Use and systemic S. aureus infections. In this study systemic infections refers to bacteremia or Infectious Endocarditis. Participants who meet inclusion and exclusion criteria will receive a single 1200mg infusion of oritavancin to complete 4 weeks of antibiotic therapy (including the inpatient phase) for isolated bacteremia and 6 weeks for IE. Participants will be evaluated weekly until completion of treatment and then at week 4 and week 6 after the infusion of oritavancin. Participants will have blood drawn at each visit to monitor for toxicity and pharmacokinetics and will be evaluated clinically and by culture for the presence of relapse of the infection. At the last visit, participants will have an echocardiogram.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Oritavancin Injection in people with Staphylococcus Aureus Bacteremia and Staphylococcus Aureus Endocarditis, run by University of Pennsylvania 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 10 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The record says: withdrawn, as of the sponsor's last update on 6 Apr 2022. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 was withdrawn before enrolling participants, so there are no results.
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?
Frequency of grade 3 or 4 systemic (i.e., not a local reaction) adverse events associated with the administration of oritavancin (time frame: 6 weeks). 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 6 Apr 2022.
