Description: Vilaprisan, also known as BAY1002670 or BAY10-02670, is a potent and selective oral progesterone receptor modulator that holds the promises of long-term treatment of patients with symptomatic uterine fibroids. BAY1002670 in subnanomolar concentrations exhibits a highly selective binding profile and antagonistic activity for the PR. These properties are also reflected in its action in two progesterone-dependent animal models that assess the termination of pregnancy and endometrial transformation. In a human fibroid xenograft model BAY 1002670 showed a marked dose-dependent reduction of fibroid tumour weight gain of 95% at a dose of 3 mg/kg/day (P < 0.005).
