About this study
The proposed study aims to evaluate the CNS penetration of telavancin in a critically ill population using cerebrospinal fluid (CSF) drawn from external ventricular drains (EVDs). Patients with EVDs were chosen as the target population because they frequently require prolonged admission to the intensive care unit and drainage of CSF in order to prevent hydrocephalus. The estimated sample size is 20 subjects. This is a prospective cohort of patients with SAH. Patients will be included if they have an in-dwelling EVD, aged 18-85 years old.
Subjects will receive telavancin 10mg/kg (maximum 1000mg) every 24 hours for 3 consecutive doses. Serial serum and CSF samples will be obtained. An 8-hour urine collection will be completed on study day 2 in order to define the patient's measured creatinine clearance.
Read the detailed description
Telavancin exhibits potent and durable activity against target pathogens for bacterial meningitis and ventriculitis. There is a potential role for telavancin in treating Gram positive CNS pathogens, particularly in patients with resistant pathogens or in those who are intolerant to other commonly used antimicrobials. The proposed study aims to evaluate the CNS penetration of telavancin in a critically ill population using cerebrospinal fluid (CSF) drawn from external ventricular drains (EVDs) in patients who have had spontaneous subarachnoid hemorrhage (SAH). Patients with SAH were chosen as the target population because they frequently require prolonged admission to the intensive care unit and drainage of CSF in order to prevent hydrocephalus. The estimated sample size is 15 subjects.
Methods: This is a prospective cohort of patients with SAH. Patients will be included if they have a spontaneous SAH, aged 18-65 years old, Hunt-Hess score of 1-4 \& has an actively draining ventriculostomy. Patients will be excluded if they have a history of telavancin or similar agents, reduced renal function (estimated creatinine clearance < 50ml/min) at the time of consent, severe anemia (hemoglobin < 7gm/dl), vulnerable population (pregnant, prisoner).
Subjects will receive telavancin 10mg/kg (maximum 1000mg) every 24 hours for 3 consecutive doses. Baseline serum and CSF samples will be drawn before the initial dose of telavancin. Serial serum and CSF samples will be obtained after the first and third doses (1, 3, 6, 23 hours after infusion). A terminal concentration will also be obtained approximately 48 hours after the last dose. An 8-hour urine collection will be completed on study day 2 in order to define the patient's measured creatinine clearance.
Major Goals Goal 1. Determine the CNS penetration of telavancin in critically ill patients with SAH. Serial CSF and serum samples will be obtained from SAH patients with EVDs before and after scheduled telavancin doses in order to determine the degree of CNS penetration of telavancin.
Goal 2. Describe the pharmacokinetics of telavancin in critically ill patients with SAH. Patients with SAH frequently exhibit augmented renal clearance.(5) This increase in renal clearance has been demonstrated to affect the pharmacokinetics of numerous renally-eliminated medications. Volume of distribution may also be affected for many medications (such as telavancin) due to the frequent aggressive measures needed to maintain euvolemia or hypervolemia in some instances (due to SAH-induced vasospasm) and changes in serum albumin concentrations.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Telavancin Injection in people with Subarachnoid Hemorrhage, Aneurysmal, run by Aaron Cook 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 2 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 26 Dec 2025. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Aaron Cook, PharmD (859-323-9258, amcook0@email.uky.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Determine the CNS penetration of telavancin in critically ill patients with External Ventricular Drainage (time frame: 3 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 NCT06119061, which also lists 8 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 26 Dec 2025.
