About this study
Official title: Bioequivalence Study Between Two Medications for Oral Administration of Minocycline in 100 mg Oral Solids in Healthy Volunteers
The aim of the study is to compare the bioavailability of two medications containing 100 mg of minocycline in capsules to determine bioequivalence. They are Minocycline (Minocin® is a registered trademark of Wyeth Holdings Corporation), and Minocycline (Minopac® is a registered trademark of LABORATORIOS DERMATOLOGICOS DARIER, S.A. DE C.V.). Study design is randomized, open, cross-over with two single administrations with two periods and two sequences with a wash-out period of 7 days between the periods. Subjects in the study will be 25 healthy male volunteers, 18-55 years, Blood samples will be obtained at 0.0, 0.33, 0.66, 1.0, 1.33, 1.66, 2.0, 2.33, 2.66, 3.0, 4.0, 6.0, 8.0, 12.0, 16.0, 24.0, 48.0, and 72.0 hours after medication administration in each period. Plasma minocycline levels will be determined by HPLC method with UV detection with previously validated method. Minocycline concentration data will be used to calculate Cmax, AUC0-t, and AUC0-inf with WinNonlin 5.3 software. The log transformed pharmacokinetics parameters of test and reference medications will be compared calculating ratios and 90% confidence intervals. Any adverse event will be reported.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Minocycline 100mg in people with Skin Infections (Acne), run by GlaxoSmithKline.
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 1 inclusion and 2 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 Jun 2017. 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?
Peak Plasma Concentration (CMAX) of drug minocycline (time frame: 0.0, 0.33, 0.66, 1.0, 1.33, 1.66, 2.0, 2.33, 2.66, 3.0, 4.0, 6.0, 8.0, 12.0, 16.0, 24.0, 48.0, and 72.0 hours postdose). 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 22 Jun 2017; AzTrials last refreshed its copy on 31 Oct 2026.
