What is the role of estrogens in the human body?

• E4: native estrogen produced by human fetus around week 9

• Fetal plasma levels 12x higher than those of mother

• E4’s broad potential for use in Women’s Health validated in multiple peer-reviewed academic journals1-8

• E4-based programs protected by 30 patent families, including synthesis pathway until 2032

E4 (Estetrol) Answer from Nature with Unique Potential

E4 (Estetrol) Unique Agonist-Antagonist Mode of Action

14© 2019 | Mithra Investor Presentation | March 2019

Cells exhibit 2 types of estrogen receptors (ERα): membrane (1) and nuclear receptors (2). Depending on the tissue either the membrane or the nuclear receptor is predominantly active.

E4 acts differently compared to other estrogens depending on the tissue:

• Agonist on the nuclear receptor : E4 activates the nuclear Estrogen receptor in bone, vagina, endometrium stability & heart to provide beneficialeffects (as other estrogens)

• Antagonist on the membrane receptor: E4 blocks the estrogen receptor in breast and has a neutral effecton the liver (unlike other estrogens)

Safety concerns of estrogens: an unmet clinical need potentially addressed by E4

E4 has the potential to address most of these concerns:

+ Favorable VTE risk profile¹,#

+ Favorable drug-drug interaction profile⁴+ Minimal increase of triglycerides5, ‡

+ Lower breast pain6 and lower carcinogenicpotential in the presence of E2*,2,3,7

+ Good user acceptability, body weight control, excellent cycle control, improved spotting and general well-being6,8

Estrogen’ssystemic effects:

- Heart and liver: increased risk of Myocardial infarction, Thromboembolism

- Brain: increased risk of Stroke- Uterus: increased risk of Endometrial

cancer- Breast: increased risk of Breast cancer- Quality of life: bleeding, cycle control

• Note: Hoogland score is a validated tool to assess ovarian function and evaluate ovulation inhibition, which is assessed by transvaginal ultrasounds (TVUS) monitoring of follicle size and analysis of serum E2 and progesterone levels, and consequently classified according to a 6-point scoring (1 = no ovarian activity; 2 = potential activity; 3 = non-active follicle-like structure (FLS); 4 = active FLS; 5 = luteinised unruptured follicle (LUF); 6 = ovulation).

Donesta® Phase IIb: Positive Results Efficacy on Secondary endpoints & promising safety profile (1/2)

• Highlights secondary efficacy endpoints:o Statistically significant result for vaginal maturation index (VVA/vulvo-vaginal atrophy; p < 0.001)

o Strong improvement in Menopause Rating Scale (Quality of life)

o 15 mg dose shows lower bone turnover vs placebo at Week 12

Near-significant decrease for CTX-1 & significant decrease for osteocalcin marker (p < 0.05) vs placebo

• At 15 mg, need to add progestin for non-hysterectomized women to curb endometrial proliferation

• However, no endometrial hyperplasia detected in any of the study subjects

• Safety parameters confirming published results on hemostatic profile of E4:• Limited impact on pro- and anti-coagulant factors• Encouraging limited increase in SHBG levels (Sex-hormone

binding globulin), as marker of hepatic estrogenicity

• Significant improvement in metabolic factors, especially for 15 mg dose, pointing to promising cardiovascular safety profile:• Glucose levels significantly improve, as measured by

hemoglobin A1C (p < 0.001 vs placebo)• Metabolism of lipids also significantly improved (p < 0.05 for

increase in cholesterol-HDL levels vs placebo for 10 & 15 mg)• Only very slight increase in triglyceride levels

Donesta® Phase IIb: Positive Results Efficacy on Secondary endpoints & promising safety profile (2/2)

Positive top line Phase IIb data strongly support further Donesta® development, as a unique next-generation hormone therapy and should enhance the oral therapeutic utility of E4

Unmet clinical need for women transitioning into menopause

Need for approved treatment providing both VMS relief and effective contraception, while

addressing increased safety concern for women in perimenopause

• Perimenopause, or menopause transition, begins several years before menopause when the ovaries gradually begin to make less estrogen

• Starts in a woman’s 40’s (average age is 45.5) and ends at the menopause• Symptoms seriously impact the quality of life* • Contraception is needed alongside VMS relief• While COC’s can alleviate these symptoms, guidance advises the use of the lowest hormonal

dose to limit VTE risks (which is increased at age > 40) • Pregnancy above 40 presents a safety risk for the women, as well the baby

30 µg EE/150 µg LNG

20 µg EE/3 mg DRSP

• Analyze impact on coagulation (blood clotting) and fibrinolysis (breakdown of clots) of Estelle®,

• Determine the risk profile of a novel COC for deep venous thrombosis (DVT) and pulmonary embolism.

• Less pronounced effects of E4/DRSP and EE/LNG on hemostasis parameters than those of EE/DRSP.

• Comparable effects of E4/DRSP to EE/LNG (second generation COC).

• Lower impact of E4/DRSP vs EE/DRSP on a number of hemostatic parameters confirms the importance of the estrogen selected for COC use
