Primary Outcome Measures:
  • Pharmacokinetics [ Time Frame: 0 - 60 Days ] [ Designated as safety issue: No ]
    Estrogen and progesterone plasma concentrations and pharmacokinetic parameters.


Secondary Outcome Measures:
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 0 - 60 days ] [ Designated as safety issue: Yes ]
    Number of Participants with Adverse Events as a Measure of Safety and Tolerability. Adverse events will be evaluated through periodic clinical evaluations and laboratory tests (comparison between enrollment and discharge).

Detailed Description:

Sites: 1

Phase: 1

Main objective:

To determine plasmatic profiles and pharmacokinetic parameters of estradiol and progesterone on each of the formulations studied, after multiple-dose administration.

Secondary objectives:

To determine bioavailability of each of the formulations studied, after multiple-dose-administration. Describe tolerability of each of the formulations studied, after multiple-dose administration.

Study design: Randomized, controlled, open-label, parallel, pharmacokinetic study

Investigational Products:

  • Estradiol and progesterone microspheres aqueous suspension (1 mg/20 mg)
  • Estradiol and progesterone microspheres aqueous suspension (0.5 mg/15 mg)

Study subjects: 30 postmenopausal women 45 - 65 years old

Brief description: After written informed consent, 30 eligible women will be randomized to study treatments (one IM injection each 28 days, for a total of 4 doses). Blood samples will be obtained for pharmacokinetic study.
