About this study
Official title: An Open-label, Randomized, 2-way Crossover Study to Evaluate the Effect of Food on Levofloxacin Pharmacokinetics From an Oral Solution Formulation
The main purpose of the study was to evaluate the effect of food on the single-dose pharmacokinetics of an oral solution of levofloxacin.
Read the detailed description
In this single-dose study conducted at a single center, the effect of food on the pharmacokinetics of levofloxacin was studied in 24 healthy men and women aged 18 to 55 years old. Subjects were assigned different treatments based on chance; both the researcher and the study participant knew the treatment being administered. The study consisted of 3 phases: a screening phase, an open-label treatment phase consisting of 2 treatment periods, and a post-treatment phase. Subjects who met the prestudy eligibility criteria were randomly assigned to 1 of 2 treatment sequence groups. In each treatment period, subjects were admitted to the study facility the evening before study drug administration and housed through 48 hours after dosing with study drug. Subjects received levofloxacin as a single oral dose of 500 mg under both fed (within 10 minutes after completion of a high-fat, high-caloric breakfast) and fasted (10-hour overnight fast) conditions according to their randomized treatment sequence. Each dosing day was separated by a washout period of at least 4 days. In each treatment period, pharmacokinetic blood samples were collected immediately prior to dosing and at 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 6, 10, 14, 24, 30, 36, and 48 hours after dosing for determination of plasma concentrations of levofloxacin. Safety evaluations, including adverse event monitoring, standard clinical laboratory evaluations (hematology, serum chemistry, and urinalysis), vital sign monitoring, and physical examinations were performed on Days 1 and 3 of each treatment period. The post-treatment phase consisted of safety evaluations performed after collection of the final pharmacokinetic blood sampling in the second treatment period. Adverse events were monitored from the time of the first study-related procedure through completion of post-treatment study procedures, or until the time of early withdrawal from the study. Levofloxacin solution administered as 2 single oral doses of 500 mg each, 1 in each treatment period, administered at least 4 days apart.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing levofloxacin oral solution in people with Healthy, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
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 7 inclusion and 6 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 22 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
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?
Evaluation of the effect of food on the single-dose pharmacokinetics of an oral solution of levofloxacin at 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 6, 10, 14, 24, 30, 36, and 48 hours after dosing.. 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 22 Dec 2016.
