About Low-Dose Estrogen Combined Hormonal Contraceptive Weekly PatchThe investigational treatment is a once-weekly transdermal contraceptive patch being developed for women of childbearing potential with a BMI below 30 kg/m² who are appropriate candidates for combined hormonal contraception (CHC) and who prefer a non-invasive, reversible option with a lower estrogen dose.

The U.S. FDA has accepted for review the New Drug Application (NDA) for the Company's investigational low-dose estrogen CHC weekly patch. The NDA is accepted under the FDA's 505(b)(2) regulatory pathway, and the FDA has assigned a target action date (PDUFA) of July 30, 2026. The NDA is supported by results from a multicenter, open-label, single-arm, Phase 3 study (NCT05139121), which evaluated the safety and contraceptive efficacy of the investigational low-dose estrogen CHC weekly patch, and which demonstrated a favorable efficacy and safety profile and strong patch adhesion performance.

The investigational low-dose estrogen CHC weekly patch aims to address an important need for women seeking a reversible birth control method that offers a lower dosage of estrogen in a weekly patch with potential best-in-class adhesion performance. This investigational treatment option builds upon the Company's established capability in transdermal drug delivery and represents a lifecycle advancement of the contraceptive patch, Xulane®(norelgestromin and ethinyl estradiol transdermal system) 150/35 mcg per day.
