About this study
Official title: An Open-label, Randomized, 3-way Crossover Study to Evaluate the Bioequivalence of an Oral Suspension Formulation, an Oral Solution Formulation, and the Marketed Tablet Formulation of Levofloxacin in Healthy Subjects
The primary objective of the study was to assess the bioequivalence of the oral suspension formulation, the oral solution formulation, and the marketed tablet formulation of levofloxacin, with the marketed tablet as the reference.
Read the detailed description
In this single-dose study conducted at at single center, 3 oral formulations of levofloxacin (tablet, suspension, and solution) were assessed for their bioequivalence in 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 a screening period, 3 open-label treatment periods separated by washout periods of at least 4 days between doses, and a post-treatment period. Subjects received a single dose of all 3 study formulations, administered as a single dose of each formulation on Day 1 of each treatment period. Blood samples were collected on Days 1, 2, and 3 of each treatment period immediately before 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 measurement of levofloxacin concentration. Subjects were admitted to the study site prior to dosing and remained through the 48-hour measurements on Day 3. The post-treatment period included physical examination and clinical laboratory testing to ensure subject safety before being discharged from the study. Safety evaluations, including adverse event monitoring, standard clinical laboratory evaluations (hematology, serum chemistry, and urinalysis), vital sign monitoring, and physical examinations, were monitored throughout the study.
Two cohorts of 36 subjects each were enrolled in the study. The first cohort received a single dose of study drug and completed Period 1; the study was then stopped and reinitiated. Subjects from the first cohort completed early termination procedures; their data were included in safety analyses, however, no blood samples for levofloxacin concentrations were analyzed or included in pharmacokinetic analysis. Thirty-four subjects in the second cohort completed all study procedures. Levofloxacin oral suspension (125 mg/5 mL), levofloxacin oral solution (125 mg/5 mL), and levofloxacin tablet (500 mg) administered on Day 1 of each treatment period.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Levofloxacin oral suspension; Levofloxacin oral solution; and Levofloxacin marketed tablet formulations 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 6 inclusion and 7 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?
Assessment of the bioequivalence of the oral suspension formulation, the oral solution formulation, and the marketed tablet formulation of levofloxacin, on Days 1, 2, and 3, using the marketed tablet as the reference.. 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.
