Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Change in Bone Mineral Density Bone Loss Drug: LF111 (drospirenone 4 mg oral tablet) or drospirenone (DRSP) 3.5 mg chewable tablet Phase 4

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.

Arm Intervention/treatment
Experimental: Cohort 1 (adolescents aged 14-17) Hormonal Treatment Arm
Subjects in the USA will choose to use the LF111 tablets or drospirenone (DRSP) 3.5 mg chewable tablets; 1/3 of subjects in the USA should receive DRSP 3.5 mg chewable tablets. Only LF111 will be available to subjects in Europe.
Drug: LF111 (drospirenone 4 mg oral tablet) or drospirenone (DRSP) 3.5 mg chewable tablet
LF111 (drospirenone 4 mg tablet orally daily on days 1-24, followed by placebo tablet orally daily on days 25-28) or drospirenone (DRSP) 3.5 mg chewable tablet chewed daily on days 1-24, followed by placebo tablet chewed daily on days 25-28) (USA only). Subjects in the USA who choose to use the hormonal contraceptive method may choose between LF111 and DRSP 3.5 mg chewable tablets. The DRSP 3.5 mg chewable tablets are not available to subjects in Europe. Subjects in Europe who choose to use the hormonal contraceptive method will only receive LF111.

No Intervention: Cohort 1 (adolescents aged 14-17) Non-Hormonal Contraceptive Arm
Subjects in this group will not receive any investigational product. They will be free to use a non-hormonal contraceptive method of their choice. Non-hormonal contraceptive methods include barrier contraceptive methods (condoms, female condoms, cervical caps, diaphragms, and contraceptive sponges), double barrier methods, non-hormonal IUD (e.g., copper IUD), surgical female sterilization, vasectomized partner, spermicides, and sexual abstinence.
Experimental: Cohort 2 (adults aged 18-45) Hormonal Treatment Arm
Subjects in the USA will choose to use the LF111 tablets or drospirenone (DRSP) 3.5 mg chewable tablets; 1/3 of subjects in the USA should receive DRSP 3.5 mg chewable tablets. Only LF111 will be available to subjects in Europe.

Subjects in the USA who choose to use the hormonal contraceptive method may choose between LF111 and DRSP 3.5 mg chewable tablets. The DRSP 3.5 mg chewable tablets are not available to subjects in Europe. Subjects in Europe who choose to use the hormonal contraceptive method will only receive LF111.

No Intervention: Cohort 2 (adults aged 18-45) Non-Hormonal Contraceptive Method Arm
Subjects in this group will not receive any investigational product. They will be free to use a non-hormonal contraceptive method of their choice. Non-hormonal contraceptive methods include barrier contraceptive methods (condoms, female condoms, cervical caps, diaphragms, and contraceptive sponges), double barrier methods, non-hormonal IUD (e.g., copper IUD), surgical female sterilization, vasectomized partner, spermicides, and sexual abstinence.
