  • Adult

Who may be able to join

  • Male volunteers. Ages between 18 and 45 years old. BMI (Body Mass Index) between 20 to 26 kg/m2. Anti-doping tests negative results.

  • Normal Electrocardiogram and Chest X-rays. In exception cases, accepted may be a candidate for which any previously mentioned test is exceeded regarding considered valid maximum and minimum accepted normal values, as long as it involves an isolated value and there are no other manifestations which could allow assuming that a given value is related to a disease or is remnant of another. These cases must be approved by clinical area and declared as "Non-clinically significant".
  • -

Who cannot join

  • Electrocardiographic Anomalies; radiological Anti-doping tests positive results, Positive results regarding RPR; VIH and AgsHB tests. Personal or family history of allergy to medication in question. Having any kind of allergy, since these persons are in higher risk of suffering from medicamentous allergy.
  • Tobacco use. Recreational drug use. Persons undergoing any medical treatment. Existence of concurrent or intercurrent disease. Existence of justified doubt regarding questionnaire answers truthfulness. Having participated in bioequivalence or bioavailability studies or having donated blood 2 months before the study.

About this study

Official title: Bioequivalence Study for an Isotretinoin Pharmaceutical Preparation - Capsules. Crossover, Randomized, Single Dose, Two Treatments, Two Periods and Two Sequences With Meal (Breakfast) Study

The objective of this study was to confirm if two formulations of isotretionin (capsules) are bioequivalent.

Test product was Oratane® 20 mg (Laboratorios Dermatológicos Darier) and reference product Roaccutan® 20 mg (Productos Roche). Two capsules administered together were the single dosage.

The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fed conditions.

The population was composed of 36 healthy volunteers, male adults between 18-45 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Isotretinoin 40 mg in people with Skin Infections (Acne), run by GlaxoSmithKline at 1 site in Mexico.

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 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 18 Jul 2017. 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 Mexico. 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 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 isotretinoin (time frame: 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24.0, 36.0, 48.0, 60.0, 72.0 and 96.0 hours 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 18 Jul 2017.
