Trial Summary

What is the purpose of this trial?

This trial tests different doses of a drug called LB, given as injections, in healthy women with normal ovulatory function. It aims to see how the drug affects their menstrual cycles and how it moves through their bodies. Levonorgestrel butanoate (LB) is a new formulation designed to be a long-acting injectable contraceptive.

Healthy women aged 18-40 with a BMI under 40, regular menstrual cycles, and no chronic medical conditions. They must not be at risk for pregnancy during the study, have an intact uterus with at least one ovary, and agree to use non-hormonal contraception if sexually active. Exclusions include hypersensitivity to progestins, drug abuse, uncontrolled thyroid disorders, cardiovascular diseases or thrombosis risks.

My recent Pap test results meet the required guidelines and no further treatment is needed.

I have had at least 2 menstrual cycles since giving birth or having a second-trimester abortion.

Have a negative urine pregnancy test at the injection visit and no unprotected heterosexual intercourse for the previous 10 days
