Increase of our suppliers and partners global quality
oversight
We are happy to report that, by the end of 2022, we increased
our suppliers and partners global quality oversight to 30%.
Reinforcement of pharmacovigilance team
We are also proud to report that all periodic safety update
reports (PSURs) were submitted on time in 2022. These
reports are pharmacovigilance (PV) documents intended
to provide an evaluation of the risk-benet balance of a
medicinal product at dened time points during the post-
authorization phase. Each marketing authorization holder
is responsible for submitting PSURs for its own products
and should submit PSURs to the EMA according to dened
timelines.
In 2022, we also submitted all 90-days adverse event reports
on time but there were 3 late 15-days adverse event reports
out of a total of 23 reports (87%). As compliance to the
timelines provides assurance that marketing authorization
holders have adequate systems in place for the safety
monitoring of medicines on the market, the decision has
been made to transition to a new PV service provider,
effective early 2023. We also strengthened the internal PV
team with the addition of a Medical Information Ofcer
and a PV Operations Ofcer. These new hires allowed for
a continuous improvement program to have successful
internal audits and audits by partners, and further allowed
the team to bring critical functions in-house like the (deputy-)
EU QPPV and Responsible for Information.
Launch of Estelle
®
PASS study in 2023
With Estelle
®
being available for nearly two years now, a
post approval safety study (PASS) must be carried out. Post-
authorisation safety studies (PASS) are carried out after a
medicine has been authorised to obtain further information
on a medicine’s safety, or to measure the effectiveness of
risk-management measures. Estelle
®
PASS study is expected
to be launched in the second quarter of 2023 in Europe while
the protocol for the U.S. part of the PASS study is currently
being reviewed by the FDA.

and not only the environmental
prole of estetrol alone, a complementary ecotoxicity study
has been conducted at the University of Namur. The results
show that a one-month exposition of the sh to E4 (at up to
300 times the environmentally relevant concentration) with
or without DRSP didn’t affect their survival or their growth.
These studies suggest that E4, alone or in combination with
DRSP, presents a more favourable environmental prole
than ethinylestradiol at their respective environmental
concentrations. Data therefore support that E4- or E4/
DRSP-based products could be valuable eco-friendly
alternatives to products containing ethinylestradiol.
Raising awareness for more environmentally friendly
medicines
While the world gradually realizes how harmful medicine
residues are to our waters and overall biodiversity, we are
convinced of the need to continue to raise awareness on the
importance of product ecotoxicity. To this end, we engaged
in several initiatives. In 2022 our non-clinical team attended
both the European and North American congresses of the
Society of Environmental Toxicology and Chemistry (SETAC)
and presented a different poster in both congresses. They
also submitted one publication entitled “Estetrol has a
lower impact than 17α-ethinylestradiol on the reproductive
capacity of zebrash” in several scientic journals.
In November 2022 we also organized a conference at the
European Parliament that gathered researchers, industry
players and policymakers to address the direct effects of
pharmaceuticals on wildlife, knowledge and policy gaps but
also to discuss solutions to support research and innovation
for less environmentally harmful medicines. Experts from the
panel discussion highlighted the need to improve monitoring
in Europe and to increase support for the development of
more environmentally friendly drugs.
Products ecotoxicity
Favourable environmental prole for Estetrol (E4)
Estrogens, either natural or synthetical, are commonly found
in the aquatic environment and can, as endocrine disruptors,
influence the sexual differentiation of shes and disrupt
aquatic ecosystems.
Mindful of the environmental footprint of its solutions, Mithra
is committed to monitoring and reducing their environmental
impact and, as such, to conducting an environmental risk
assessment for all new Mithra product candidates.
The environmental risk assessment for our product
candidate Donesta
®
is currently being conducted as part
of our preparation for the market authorization application,
while for Estelle
®
, the studies conducted on a representative
sh species showed that estetrol, at environmental predicted
concentrations, presented none of the adverse effects
induced by the natural estrogens estrone and estradiol and
by the synthetic estrogen ethinylestradiol (EE2), i.e. reduced
egg production, delay in sexual maturation, and even
feminization. The results also indicated that estetrol has a
low potential to accumulate in living organisms and was
likely to disappear rapidly from both water and sediment.
The PEC/PNEC ratio
1
of estetrol is therefore below 1 and
we are very proud to claim that the positive environmental
prole of estetrol is highlighted in Estelle
®
’s leaflet in Europe
and Canada: “Environmental risk assessment studies with
estetrol including the Japanese medaka sh extended one
generation reproduction test indicated that the predicted
environmental exposure to estetrol will not affect the aquatic
ecosystem”.
As our objective was to characterize the environmental prole
of the Estetrol (E4)/Drospirenone (DRSP) combination of our

The PEC/PNEC ratio is the ratio between the Predicted Environmental Concentration and
the Predicted No Effect Concentration. If the PEC/PNEC ratio of a product is below 1, it means
that the use of this product will have no effect on the environment.
Environmental risk assessment studies with
estetrol including the Japanese medaka sh
extended one generation reproduction test
indicated that the predicted environmental
exposure to estetrol will not affect the
aquatic ecosystem.

Patients
As a company dedicated to women’s health, our mission
has always been to offer women innovative solutions that
address their needs and offer them better efcacy, safety
and quality of life.
> Responsible Research & Development
8 manuscripts published in scientic journals
At Mithra we value innovation and expertise to pursue
our mission of a better health for women. To this end, we
invested 53.7 million euros into research and development
in 2022. To ensure that our Research & Development teams
stay at the cutting edge in their eld of expertise, they also
attended no less than 9 international scientic congresses
with 15 abstracts and published 8 manuscripts in scientic
journals.
> Product safety and quality
The safety of our patients is of utmost importance to us.
Our goal is to ensure that our products are safe and efcient
for all patients, both during clinical trials and once they are
commercialized.
To prevent all risks associated with product safety and
quality, we of course comply with all the guidelines issued
by the regulatory authorities. Besides these strict regulations,
we decided in 2021 to pursue three additional ambitious
targets, i.e. succeed all GxP

inspections and customer
audits; digitalize Mithra’s quality system by end 2022; and
increase our suppliers and partners global quality oversight
to 30% by end 2022 and to 100% by end 2025.
100% of successful inspections and audits and 0 recall
We are proud to report that we successfully passed all our
inspections and customer audits in 2022 and that we did not
issue any recall.
Progress in digitalization of quality system
While our target of digitalizing Mithra’s quality system
by the end of 2022 is not entirely achieved, we did make
progress and the rst out of the three waves of the project is
implemented, meaning that quality document management
and trainings are now fully digitalized. Wave 2 (change,
deviation, CAPA and complaint management) and wave 3
(audit and suppliers/subcontractors management) will be
implemented in the near future.
