Introduction
Ethinyl estradiol and levonorgestrel are two active ingredients commonly used in combined hormonal contraceptives (CHCs). These medications are available in various forms, including oral tablets, transdermal patches, and other delivery systems. Here, we will delve into the current state of clinical trials, market analysis, and future projections for these drugs.
Clinical Trials Update
Pharmacokinetics and Drug Interactions
A recent clinical trial conducted by AstraZeneca (Study identifier: D6970C00006) focuses on the pharmacokinetics of ethinyl estradiol and levonorgestrel when co-administered with baxdrostat. This Phase 1 study involves healthy female participants and assesses the effect of multiple doses of baxdrostat on the pharmacokinetics of a single dose of combined oral ethinyl estradiol and levonorgestrel. The study is designed to evaluate the potential drug interactions and their impact on the efficacy and safety of the contraceptive[1].
Efficacy and Safety of Transdermal Patches
Agile Therapeutics has been conducting extensive research on its transdermal contraceptive patch, Twirla (AG200-15), which contains ethinyl estradiol and levonorgestrel. A Phase 3 clinical trial published in PubMed evaluated the efficacy, safety, and tolerability of this patch. The study found that the low-dose levonorgestrel/ethinyl estradiol transdermal delivery system (TDS) was effective in preventing pregnancy, although its efficacy was reduced in women with a BMI of 30 kg/m² or higher. The patch demonstrated a favorable safety and tolerability profile consistent with other combined hormonal contraceptives[4].
Regulatory Updates
Agile Therapeutics has also been engaged in discussions with the FDA regarding the design of a comparative wear study for Twirla and Xulane, a generic version of a previously marketed contraceptive patch. This study aims to demonstrate the non-inferior adhesion of Twirla compared to Xulane, following FDA guidance on assessing adhesion with transdermal and topical delivery systems[3].
