Sebela Women's Health Inc., a part of Sebela Pharmaceuticals, announced that the U.S. Food and Drug Administration (FDA) granted approval of MIUDELLA® (copper intrauterine system) for the prevention of pregnancy in females of reproductive potential for up to three years. MIUDELLA is a next-generation, hormone-free, low-dose copper intrauterine device or IUD, the first to be approved by the FDA in the United States in over 40 years.
"Sebela Women's Health is thrilled to be able to bring this hormone-free IUD option for birth control to women in the United States," said Kelly Culwell, MD, Head of Research and Development, Sebela Women's Health. "Our innovative copper IUD MIUDELLA® offers effective pregnancy prevention using less than half the copper of the currently available copper-based IUD in the U.S., utilizing a small, flexible nitinol frame. We believe these and other features of MIUDELLA may help address barriers to use, while also providing women with the hormone-free option some prefer."
Guidelines from the American College of Obstetrics and Gynecology state that long-acting reversible contraceptive (LARC) methods, including intrauterine devices and contraceptive implants, are the most effective contraceptive methods, have few contraindications, and are appropriate for almost all patients.1 While there are a variety of contraceptive methods available to women, 41.6 percent of pregnancies in the U.S. are unintended.2
MIUDELLA® is a hormone-free IUD with a flexible frame made of nitinol, a material that has super-elastic properties that enables strategic placement of the copper in a manner that allows the device to achieve similar efficacy to the currently available copper IUD with less than half the dose of copper (175mm2). MIUDELLA® uses the smallest hormone-free flexible IUD frame available in the United States, measuring 32 mm horizontally and 30 mm vertically with pre-cut retrieval strings. Miudella does not require loading by a healthcare professional; it comes fully preloaded within a tapered, rounded tip inserter with a small insertion tube diameter of 3.7 mm.3
"Considering it has been four decades since we've been able to offer women a new hormone-free IUD option, I find the clinical data supporting MIUDELLA® efficacy and safety to be very exciting," said Principal Investigator David K. Turok, MD, MPH, Professor, Department of Obstetrics and Gynecology, University of Utah. "This innovative intrauterine device may allow for improvements in discontinuation rates due to pain and bleeding and in expulsion rates. This would be very meaningful for women looking for hormone-free options."
About MIUDELLA®:
MIUDELLA was investigated in three clinical trials in the U.S. in 1,904 women aged 17 to 45 years. The Phase 3 prospective, multicenter single-arm open-label study was conducted in 42 centers in the U.S. with a primary endpoint of contraceptive efficacy through 3 years of use as assessed by the Pearl Index (defined as the number of pregnancies per 100 women over one year). In the efficacy cohort from the Phase 3 study (n=1397), the first-year Pearl Index was 0.94 (95% CI, 0.43-1.78) and the cumulative 3-year Pearl Index was 1.05 (95% CI, 0.66-1.60) or 99% efficacy. Both clinicians and study participants also reported positive experiences with placement of Miudella, with an overall placement success rate of 98.8%. The most common adverse events across all three clinical trials were similar to those seen with use of IUDs – heavy menstrual bleeding, dysmenorrhea and intermenstrual bleeding.
