Mar 19In its annual report, Evofem notes that an analysis of secondary market research from 2017 suggests that approximately 60 million of women in the greater European market (inclusive of the EU), eastern Europe, and the Commonwealth of Independent States were found to showcase the characteristic of hormone avoidance or were hormone indifferent. Evofem believe Amphora will have the ability to significantly grow the European birth control market through the conversion of non-users, hormonal contraceptive users, and those who will supplement their current methods. Evofem is currently assessing how Amphora is going to be regulated in the EU and expects it is going to be regulated as a drug. No plans for EU filing described [6].

Trial or other data

Jun 19Though key opinion leaders (KOLs) stressed the need for non-hormonal contraceptive options, they were sceptical about Amphora’s efficacy and expressed some doubt about its potential to prevent pregnancy when used as a sole method of contraception. They suggested it will become a method that ultimately should be recommended along with a second barrier method for control, which may reduce its popularity [4].
