International Active Surveillance Study: Safety of Estrogen Estetrol (E4) Contraceptive Study (INAS-SEECS)

Recruiting now

Conditions studied: Contraception

In brief

The combined oral contraceptive (COC) containing estetrol (E4) and drospirenone (DRSP) (E4/DRSP) is a novel oral contraceptive containing a fixed dose of E4 (14.2 mg) and DRSP (3 mg). The proposed study will address post-market requirements for E4/DRSP under section 505(o) in response to the Food and Drug Administration (FDA) request. The primary objective of the study is to characterize and compare the risks of E4/DRSP with EE/DRSP and E4/DRSP with a pooled cohort of users of EE/LNG, EE/NETA, and EE/NGM combinations (non-DRSP-containing COCs) in a study population of actual users of these preparations under routine clinical practice. The main clinical outcome of interest is VTE.
