- Estelle ® Phase III study in US/Canada remains on track to report top line data in Q1 2019

Liège, Belgium, 30 October 2017 - Mithra (Euronext Brussels: MITRA), a company specialized in Women's Health, today announces the completion of recruitment in the E4 Freedom Phase III study of Estelle® in the US and Canada. Estelle® is Mithra's combined oral contraceptive (COC) candidate composed of 15 mg Estetrol (E4) and 3 mg drospirenone (DRSP). Top-line data, based on 13 cycles of treatment, remain on track to be reported in the first quarter of 2019.
The Phase III Estelle® study in the US & Canada is a multicenter open-label single arm study that has enrolled 2148 subjects aged 16-50 years, of whom 1940 subjects are aged 16-35 years.
Recruitment for the separate European/Russian Phase III study was completed in February 2017 and top line results from this study are expected in Q3 2018. A total of 1577 women were enrolled in this study, almost 8% of which already successfully completed 13 cycles of Estelle® as well as the end of study visit.
François Fornieri, CEO of Mithra, commented: "Today's announcement marks another important step in the development of Estelle®. We are looking forward to the outcome of the Phase III trial in Q1 2019, which we hope will corroborate earlier studies indicating that Estelle ® has the potential to exhibit a better safety and efficacy profile compared to currently-available COCs . Moreover, the fact that 57% of US study subjects already completed over half of the treatment cycles may indicate the good user acceptability profile of Estelle® . We believe that Estelle® has the potential to become a true 'next-generation' contraceptive option, including in North America, a market worth 35% of the USD 22bn worldwide contraceptive market.

About the E4 Freedom Estelle® Phase III study in US/Canada
The Phase III Estelle® study design in the US & Canada is an open-label single arm study that has enrolled 2148 subjects aged 16-50 years of whom 1940 subjects are aged 16-35 years. Estelle® is Mithra's combined oral contraceptive (COC) candidate composed of 15 mg Estetrol (E4) and 3 mg drospirenone (DRSP).
The study is taking place in approximately 77 centres across the US and Canada, and will involve subject treatment for a period of 12 months (13 cycles; 1 cycle = 28 days). The primary outcome measures the number of pregnancies per 100 women per 12 months of exposure (Pearl Index; PI) in subjects aged 16 to 35 years old.
The secondary outcomes will measure the method failure PI in the primary population as well as the PI within the overall study population (16-50 years). Also, bleeding profile, safety and tolerability, and general wellbeing of the subjects (measured by two questionnaires) are analyzed. A pharmacokinetic (PK) substudy will assess the effect of various individual characteristics/covariates (such as race and BMI) on the PKs of 15 mg E4/3 mg DRSP.
