Study summary

This clinical trial evaluated the comparative bioavailability of two injectable suspension formulations of medroxyprogesterone acetate + estradiol cypionate, a test (Depomês®, 25 mg/mL medroxyprogesterone acetate + 5 mg/mL estradiol cypionate, Biolab Sanus Farmacêutica Ltda.) and a reference formulation (Cyclofemina®, 25 mg/0.5 mL medroxyprogesterone acetate + 5 mg/0.5 mL estradiol cypionate, Millet Roux Ltda.) in healthy female volunteers after a single intramuscular dose administration. In addition, this study also evaluated the safety and tolerability of these drugs.

Read the detailed description

This study was performed in a monocentric, open label, parallel design, with 2 treatments, 1 period, in which twelve subjects received the test product (Depomês®, 25 mg/mL medroxyprogesterone acetate + 5 mg/mL estradiol cypionate, Biolab Sanus Farmacêutica Ltda.) and twelve subjects received the reference product (Cyclofemina®, 25 mg/0.5 mL medroxyprogesterone acetate + 5 mg/0.5 mL estradiol cypionate, Millet Roux Ltda.). The formulations (test or reference) were administered in a single intramuscular dose (1 ampoule) after an overnight fast (approximately 8 h). Blood samples (9 mL) were collected via a venous catheter into heparinized tubes at times pre-dose (0 h) and 6, 12, 24, 48, 72, 96, 120, 168, 240, 288, 336, 432, 504, 672, 840, 1008, 1176, 1344, 1512, 1680, 1848, and 2016 h after drug administration to measure medroxyprogesterone; and pre-dose (-48, -24 and 0 h) e 2, 4, 6, 8, 10, 12, 24, 48, 72, 96, 120, 168, 240, 288, 336, 432, 504, 672, 840, and 1008 h after drug administration to measure estradiol cypionate.

The safety assessment was based on recording adverse events throughout the study duration. The subjects systolic and diastolic pressures, heart rate and temperature were determined prior and at approximately 4, 8 and 12 h after drug administration. The clinical evaluation and the laboratory tests were also performed at the end of the study.

Inclusion criteria

  • Body-mass index () ≥19.0 kg/m² and ≤ 27.5 kg/m²
  • With regular cycles, without use of hormonal (pills at least 3 months and injectables at least 1 year) and not using hormone replacement therapy
  • Not pregnant or breastfeeding
  • Good state of health
  • Non-smoker or ex-smoker for at least 6 month
  • Written , after having been informed about benefits and potential risks of the clinical trial, as well as details of the insurance taken out to cover the subjects participating in the clinical trial

Exclusion criteria

Exclusion Criteria:

  • Existing cardiac, hepatic and/or haematological diseases or pathological findings, which might interfere with the safety or tolerability and/or pharmacokinetics and/or pharmacodynamics of the active ingredient
  • History of relevant central nervous system (CNS) and/or psychiatric disorders and/or currently treated CNS and/or psychiatric disorders
  • Known allergic reactions to the active ingredients used or to constituents of the pharmaceutical preparations
  • Subjects with severe allergies or multiple drug allergies, unless it is judged as not relevant for the clinical trial by the investigator
  • Positive anti--test (if positive to be verified by western blot), HBs-AGtest (if positive to be verified by test for HBc-IgM) or anti--test
  • Admitted for any reason up to 8 weeks before the start of the first treatment period of this study
  • History of or current drug or alcohol dependence
  • Subjects who are on a diet which could affect the pharmacokinetics of the active ingredient
  • Regular intake of caffeine containing food or beverages of ≥ 500 mg caffeine per day
  • Blood donation or other blood loss of more than 400 ml within the last 3 months prior to individual enrolment of the subject
  • Participation in a clinical trial during the last 6 months prior to individual enrolment of the subject
  • Positive pregnancy test, delivery or abortion in the 12 weeks prior to the planned hospitalization date.
  • Subjects who are unable to understand the written and verbal instructions, in particular regarding the risks and inconveniences they will be exposed to during their participation in the clinical trial
Terms in these criteria, in plain language(5)

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.

BMI (body mass index)

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.

Contraception

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.

Informed consent

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.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
