Primary Outcome Measures:
  • partial and full predecidual changes in endometrial samples on the 11th day of exposure to the IMP compared to the findings on the 11th day after ovulation in the menstrual cycle, according to Noyes criteria

Secondary Outcome Measures:
  • PK profile of progesterone at the steady-state following the 25 or 50 mg/day of progesterone s.c. at the time of endometrial biopsy, local tolerability

Estimated Enrollment: 24
Study Start Date: August 2005
Estimated Study Completion Date: March 2006
Detailed Description:

This study is designed in order to assess the efficacy of the investigational product (Progesterone acqueous s.c. formulation) when it is administered at the dose of 25 and 50 mg. The induced predecidual changes will be evaluated through endometrial bioptic samplings, performed on day 11 and will be compared between the two treatment groups.

The pharmacokinetic evaluation was designed according to internationally recognised guidelines for PK studies.
