About this study
Official title: Bioavailability of a Formulation of Desogestrel 0.075 mg Coated Tablets With Regards to the Marketed Reference Product
This Pivotal study investigated the bioavailability in women of 2 tablet formulations containing Desogestrel 0.075 mg. The Pivotal study was performed at a single site with 30 subjects. Participants took 2 tablets of the test product and reference product in 2 periods and 2 sequences (either test after reference or reference after test). There was a washout of 14 days between each study period.
Read the detailed description
The primary objective of the study is to investigate the relative bioavailability of Desogestrel of 2 tablet formulations with Desogestrel 0.075 mg to demonstrate bioequivalence of both formulations in terms of rate and extent of absorption:
- Test Product: Product manufactured by Laboratorios Andrómaco S.A.
- Reference Product: Cerazette [Trademark], product of Merck Sharp and Dohme Ltda., Brasil.
The 90% confidence intervals for the intra-subject coefficient of variation (Test versus Reference Product) for the main pharmacokinetic parameters area under the plasma concentration-time curve from time zero to time t (AUC0-t) and from time zero to 72 hours (AUC0-72), and maximum plasma concentration (Cmax) for total metabolite etonogestrel was determined.
Participants were confined in the study site for approximately 36 hours during each study period (for 12 hours pre-dosing and for 24 hours post dosing) during which pharmacokinetic (PK) blood samples were obtained. 16 blood samples were taken up to 24 hours after the administration in each period. Participants returned to the site to provide additional blood samples at 48 h, and 72 h postdose.
The washout period between the two study periods was 14 days. The samples from each participant were analyzed with 2 methods of highperformance liquid chromatography-tandem mass spectrometry bioanalytical assays to quantify total Dienogest and Ethinyl estradiol in plasma.
The safety objective was to evaluate the tolerability of both formulations in women by collecting adverse events.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Desogestrel 0.075 MG in people with Bioequivalence, run by Laboratorios Andromaco S.A. at 1 site in Chile.
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 17 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 9 Jun 2020. 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 Chile. 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?
Total etonogestrel: area under the plasma concentration-time curve from 0 to 72 hours (AUC0-72). (time frame: From tablet intake and up to 72 hours after tablet intake.). The study lists 4 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 9 Jun 2020.
