Mithra Pharmaceuticals Release: Recruitment Completed In Estelle Population Pk Substudy

PRESS RELEASE

ReCRUITMENT COMPLETED IN Estelle® population PK substudy

  • Study to determine impact of demographic characteristics on the absorption, distribution and excretion of Estelle®
  • PK study is part of the Estelle® Phase III program in the US/Canada, which remains on track to report top line results in Q1 2019


Liège, Belgium, 09 August 2017 - Mithra (Euronext Brussels: MITRA), a company specialized in Women's Health, today announces that it has completed recruitment in the population PK substudy for Estelle®. This trial is part of the Estelle® Phase III E4 Freedom program currently ongoing in Europe/Russia and in the US/Canada, with results expected in Q3 2018 and Q1 2019, respectively. Estelle® is Mithra's combined oral contraceptive (COC) candidate composed of 15 mg Estetrol (E4) and 3 mg drospirenone (DRSP).

A population PK study for a novel COC is highly recommended by the US Food and Drug Administration (FDA) given the high level of socio-cultural and physical variability amongst the target population for COCs in the US. The aim of the population PK study is to determine the impact, if any, of demographic characteristics such as BMI, race, smoking and fed/fasted state on the absorption, distribution and excretion of Estelle®. The study population consists of 500 subjects aged 16-50[1].

Contraceptive studies have historically excluded obese women from clinical trials of hormonal contraceptives2 as several studies have shown that hormonal contraceptives are less effective in this group of women[2],[3]. However, for new COCs, the FDA now requests entry criteria to be more reflective of the real-world target population. Hence, this PK substudy, together with the Phase III E4 Freedom program which includes obese women, should provide valuable insights into the use of Estelle® in various subpopulations.

François Fornieri, CEO of Mithra, commented: "We are pleased to have completed recruitment in this population PK substudy for Estelle®. The inclusion of a study population that reflects real-world contraceptive use is essential for a new COC product candidate. Together with the Phase III results, which are on track to yield top line data in Q3 2018 in Europe/Russia and in Q1 2019 in the US/Canada, the PK study results may further substantiate that Estelle® offers a convenient, potentially safer and effective option versus currently marketed COCs, to a wide variety of women."
