LF111 or Drospirenone Chew vs Non-hormonal Contraceptive Methods on Bone Mineral Density in Adolescent and Adult Women

A Multicenter, Open-label, Controlled Study to Investigate the Effect of Either LF111 or Drospirenone Chewable Tablets on Bone Mineral Density (BMD) in Adolescent and Adult Women in Comparison With Non-users of Hormonal Contraceptive Methods

The primary objective of this study is to evaluate the impact of LF111 and drospirenone (DRSP) 3.5 mg chewable tablets on bone mineral density (BMD) at the lumbar spine after 12 months (13 medication cycles) of investigation in comparison to non-hormonal contraceptive methods. Secondary objectives include further evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on BMD and bone turnover after 12 months (13 medication cycles) in comparison to non-hormonal contraceptive methods and assessing the general safety and tolerability of LF111 and DRSP 3.5 mg chewable tablets in comparison to non-hormonal contraceptive methods. Exploratory objectives include evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on body fat and lean mass after 12 months (13 medication cycles) of investigation.

Study Overview

• Status: Active, not recruiting
• Conditions: Bone Loss; Change in Bone Mineral Density
• Intervention / Treatment: Drug: drospirenone 4 mg oral tablet or drospirenone 3.5 mg chewable tablet

Detailed Description

This is a Phase IV, prospective, multicenter, open-label, controlled, non-randomized trial in female subjects between 14 to 45 years of age who are postmenarcheal for at least two years and premenopausal. Subjects who choose to take the trial medication (LF111 tablet or drospirenone [DRSP] 3.5 mg chewable tablet [USA only]) will be compared to subjects who choose to use non-hormonal contraceptive methods, enrolled in a 1:1 ratio. Subjects will also be separated into two cohorts: cohort 1 as adolescents aged 14-17, and cohort 2 as adults aged 18-45.

At Visit 1 (screening), informed consent/assent will be obtained, and the screening procedures will be performed. At Visit 2 (allocation to treatment), after confirming the subject's eligibility, subjects who choose to use LF111 or DRSP 3.5 mg chewable tablets (USA only) for pregnancy prevention will be provided with LF111 or DRSP 3.5 mg chewable tablets. The subjects will attend additional on-site visits 6 months and 12 months after Visit 2 (end of investigational phase) or within one week after premature trial discontinuation for routine safety assessments.

The primary objective of this study is to evaluate the impact of LF111 and DRSP 3.5 mg chewable tablets on bone mineral density (BMD) at the lumbar spine after 12 months (13 medication cycles) of investigation in comparison to non-hormonal contraceptive methods. Secondary objectives include further evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on BMD and bone turnover after 12 months (13 medication cycles) in comparison to non-hormonal contraceptive methods and assessing the general safety and tolerability of LF111 and DRSP 3.5 mg chewable tablets in comparison to non-hormonal contraceptive methods.
