Improving the Effectiveness of Orally Dosed Emergency Contraceptives in Obese Women - Pharmacodynamics of 3.0mg LNG

Oregon Health and Science University·interventional·Posted Aug 11, 2016·Updated Jun 15, 2023

In Brief

A Phase 4 clinical trial evaluating Levonorgestrel-based emergency contraception 1.5 mg and Levonorgestrel-based emergency contraception 3.0mg for Obesity. Completed, enrolled 70 participants across 1 site.

Detailed Summary

Obese women are significantly more likely than their normal BMI counterparts to experience failure of orally-dosed emergency contraceptives. The PI's preliminary data provides evidence for testing a dose escalation strategy in an effort to provide improved efficacy from orally-dosed emergency contraceptives in obese women. The overall project will be focused on both levonorgestrel (LNG) - and ulipristal acetate-containing emergency contraception but this protocol registration is for the LNG aspect of the study procedures.
