About this study
Official title: Open, Two Periods, Two Treatments, Two Sequences, Cross-over, Randomized Study With Single Dosage of Two Oral Preparations Containing 1 g of Cephalexin (GlaxoSmithKline México, S.A. de C.V. vs. Keflex® 1g, Eli Lilly y Compañía de México, S.A. de C.V.) in Fasting Healthy Volunteers.
The objective of this study was to confirm if two formulations of cephalexin tablets are bioequivalent.
Test product was Ceporex® (1 g Cephalexin; GlaxoSmithKline) and reference product Keflex® (1 g Cephalexin; Eli Lilly). The single dosage was one tablet.
The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fasting conditions.
The population was composed of 26 healthy volunteers, both genders, adults between 18-40 years.
The comparative bioavailability of the two formulations was evaluated based in statistical comparisons of relevant pharmacokinetic parameters, obtained from data of drug concentrations in blood.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The objective of this study was to confirm if two formulations of cephalexin tablets are bioequivalent.
Test product was Ceporex® (1 g Cephalexin; GlaxoSmithKline) and reference product Keflex® (1 g Cephalexin; Eli Lilly). The single dosage was one tablet.
The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fasting conditions.
The population was composed of 26 healthy volunteers, both genders, adults between 18-40 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Cephalexin 1g tablets in people with Infections, Respiratory Tract, 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 3 inclusion and 9 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 7 Jul 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 cephalexin (time frame: 0.0, 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, and 7.0 postdosage). 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 7 Jul 2017.
