Trial Outcomes & Findings for Effects of Oral vs. Non-oral Contraceptives on the GH/IGF-1 Axis (NCT NCT02367833)
NCT ID: NCT02367833
Last Updated: 2020-03-09
Results Overview
Changes in serially-sampled fasting serum concentrations of insulin-like growth factor-1 (IGF-1) before and after 49 days of contraceptive therapy. Data were only collected for IGF-1 levels, no assays were performed for IGFBP-1, IGFBP-3, and acid labile subunit (ALS) and no raw data were collected due to insufficient funds.

Participant milestones
| Measure |
Combined Oral Contraceptives (COC)
Apri (or generic equivalent - Reclipsen) (30µg/d EE, 150 µg/d desogestrel) is a monophasic dosing regimen of 21 active and 7 placebo pills. On Day 1 of the Intervention, participants in the COC group will begin taking the COC pill. Each participant in this group will ingest active pills from the first pack each day for the first 21 days. Pills ingested on days 22 through 28 are placebo pills. A second pill pack will begin on day 29 and pills with active ingredients will be ingested from the second pack each day for days 29-49. On day 50, the participants will immediately begin a 3rd pill pack, if the post-study testing is still occurring, and will ingest a pill with active ingredients from the third pack for days 50-56 (or for as long as the post-study testing is occurring).

Contraceptive Vaginal Ring (CVR)
Participants in the CVR group (NuvaRing - 15µg/d EE/120µg/d etonogestrel) will insert a vaginal ring into the vagina on Day 1 of the intervention. The vaginal ring will be removed and discarded after 3 weeks of continuous use (days 1-21 of continuous use and removed on day 22). There will be one week (days 22-28) that will be ring-free. A new ring will be inserted for days 29-49. On day 50, the second ring will be removed, and a third ring will be immediately inserted into the vagina (if the post-study testing is still occurring). The third ring will remain in the vagina for the last week of the post-study period (days 50-56). As soon as the post-study testing is complete, subjects will remove the ring.

Control Group
The Control group will complete all procedures with the exception of contraceptive therapy.
