Dienogest INAS Study

Trial purpose

The INAS-SCORE study was designed as an international, prospective, controlled, non-interventional cohort study. The study was started in Europe and was extended to the US after the launch of the new regimen. New users of an OC (starters or switchers) are accrued by a network of prescribing physicians. Even in the event of high drop-out rates, a 3 to 5-year follow-up of 50,000 women should be sufficient to document about 150,000 women-years. Baseline and follow-up information are collected via a self-administered questionnaire. All self-reported clinical outcomes of interest will be validated via health care professionals. Classification of reported outcomes as "confirmed" or "unconfirmed" will be checked via blinded, independent adjudication. A multifaceted 4-level follow-up procedure proved to ensure low loss to follow-up rates.
The main clinical outcomes of interest for the short and long-term follow-up are cardiovascular events, primarily deep venous thrombosis, pulmonary embolism, acute myocardial infarction, and cerebrovascular accidents.
