February 22, 2018 updated by: Gilberto De Nucci, Galeno Desenvolvimento de Pesquisas Clínicas

Comparative Bioavailability Study of Two Injectable Suspension Formulations, a Test (Medroxyprogesterone Acetate 25 mg/mL + Estradiol Cypionate 5 mg/mL) vs. a Reference (Medroxyprogesterone Acetate 25 mg/AMP + Estradiol Cypionate 5 mg/AMP)

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.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
