A Phase 3 interventional study of ethinyl estradiol + levonorgestrel + folic acid and Folic Acid in Contraception, sponsored by Galeno Desenvolvimento de Pesquisas Clínicas. Completed at 1 site in Brazil. Open to female participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-12-04.

This trial evaluated folic acid supplementation after oral administration of the ethinyl estradiol + levonorgestrel + folic acid (0.02 mg + 0.10 mg + 0.4 mg) coated tablet (Level-Fol® Biolab Sanus Farmacêutica, São Paulo, Brazil) in healthy female volunteers, based on statistical comparisons of folate levels in erythrocytes. Its safety and tolerability was also evaluated.
This Phase III trial was performed as a monocentric, open label, randomized design, with 1 treatment regimen, in 3 cycles (12 weeks), with administration in multiple doses, in which the healthy volunteers received one coated tablet of the test product - ethinyl estradiol + levonorgestrel + folic acid, 0.02 mg + 0.10 mg + 0.4 mg (Level-Fol® Biolab Sanus Farmaceutica, Brazil) for 21 days and a placebo coated tablet containing folic acid 0.4 mg only (Biolab Sanus Farmaceutica, Brazil) on the last 7 days of the cycle.
The subjects were required to present to the Clinical Unit for every drug administration, which was assisted by a member of the research team. Blood samples of 15 mL were collected via direct venepuncture into tubes containing 50 µL of ethylenediaminetetraacetic acid (EDTA) at pre-dose, 1st, 21st, 28th, 29th, 49th, 56th, 57th, 77th and 84th day of treatment.
Te safety assessment was based on recording adverse events throughout the study duration as well as through the monitoring of vital signs and evaluation of laboratory tests and ECG.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
