A STUDY TO EVALUATE THE PK AND PD OF IM OR SQ INJECTIONS OF LEVONORGESTREL BUTANOATE (LB) FOR FEMALE CONTRACEPTION

['FUNDING_OTHER'] · HEALTH DECISIONS, INC. · NIH-11251139

This study is testing a new long-lasting birth control shot called levonorgestrel butanoate, which is made for women, especially those who are overweight and may have a higher risk of blood clots, to see how well it works and how it moves through the body, while offering a safer and easier option than taking a pill every day.

What this research studies

This research investigates a new long-acting injectable contraceptive called levonorgestrel butanoate (LB), designed specifically for women, particularly those who are obese and at risk for venous thromboembolism (VTE). The study aims to assess the pharmacokinetics (how the drug moves through the body) and pharmacodynamics (the effects of the drug) of LB when administered via intramuscular or subcutaneous injections. By providing an estrogen-free option, this contraceptive aims to reduce the risk of VTE while offering a more convenient alternative to daily oral contraceptives. Participants will be monitored for adherence and effectiveness, contributing to the development of safer contraceptive methods.

Who could benefit from this research

Good fit: Ideal candidates for this research are women of childbearing age, particularly those who are obese and seeking estrogen-free contraceptive options.

Not a fit: Patients who are not seeking contraception or those who do not have concerns related to obesity may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a safer and more effective contraceptive option for women, especially those who are obese.

How similar studies have performed: Previous research has shown success with other long-acting contraceptive methods, but this specific injectable formulation is a novel approach.
