研究概览
简要总结
This study is being conducted to compare the effects of a 91-day oral contraceptive (OC) to a 28-day OC regimen on bone mineral density (BMD) in adolescent females.
详细描述
Participants will be randomized to either a 91-day OC or a 28-day OC. Participants not seeking hormonal contraception who meet eligibility criteria will serve as a control group. Duration of the study for each study participant will be approximately 13 months.

研究组 & 干预措施
91-day Levonorgestrel Oral Contraceptive
Participants received a 91-day regimen consisting of 84 consecutive days of active combination tablets containing 150 μg levonorgestrel (LNG)/30 μg ethinyl estradiol (EE), followed by 7 days of 10 μg EE tablets for a total of 52 weeks (4 consecutive 91-day cycles).
干预措施: 91-day Levonorgestrel Oral Contraceptive (Drug)
28-day Levonorgestrel Oral Contraceptive
Participants received a 28-day regimen consisting of 21 consecutive days of active combination tablets containing 100 μg LNG/20 μg EE followed by 7 days of placebo tablets for a total of 52 weeks (13 consecutive 28-day cycles).
干预措施: 28-day Levonorgestrel Oral Contraceptive (Drug)
结局指标
主要结局
Percent Change From Baseline to 12 Months in Lumbar Spine Bone Mineral Density (BMD)
时间窗: Baseline and Month 12
Bone mineral density was measured by dual energy X-ray absorptiometry (DXA) scan. DXA scans were interpreted centrally by blinded, certified technologists. Percent change from Baseline was calculated as (BMD at Month 12 - BMD at Baseline)/BMD at Baseline \* 100%.
次要结局
- Change From Baseline in Proximal Femur Bone Mineral Density(Baseline, Month 6 and Month 12)
- Change From Baseline in Lumbar Spine Bone Mineral Density(Baseline, Month 6 and Month 12)
- Change From Baseline in Lumbar Spine Bone Mineral Content (BMC)(Baseline, Month 6 and Month 12)
- Change From Baseline in Total Body Bone Mineral Content (BMC)(Baseline, Month 6 and Month 12)
- Change From Baseline in Bone-specific Alkaline Phosphatase(Baseline, Month 6 and Month 12)
- Change From Baseline in Serum Deoxypyridinoline(Baseline, Month 6 and Month 12)
- Change From Baseline in Serum Osteocalcin(Baseline, Month 6 and Month 12)
- Change From Baseline in Serum Procollagen 1 N-terminal Propeptide(Baseline, Month 6 and Month 12)
- Change From Baseline in Serum Type I Collagen N-telopeptide(Baseline, Month 6 and Month 12)
- Number of Participants With Adverse Events (AEs)(12 months)
- Change From Baseline in Proximal Femur Bone Mineral Content (BMC)(Baseline, Month 6 and Month 12)
- Change From Baseline in Total Body Bone Mineral Density(Baseline, Month 6 and Month 12)
