Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensation Arrangements of Certain Officers.

On June 17, 2020, the Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of Millendo Therapeutics, Inc. (the “Company”) approved amendments to the Millendo Therapeutics, Inc. (formerly OvaScience, Inc.) 2012 Stock Incentive Plan (the “2012 Plan Amendment”) and the Millendo Therapeutics, Inc. 2019 Equity Incentive Plan (the “2019 Plan Amendment”, and together with the 2012 Plan Amendment, the “Plan Amendments”). The Plan Amendments, effective June 17, 2020, amend the Company’s 2012 Stock Incentive Plan and 2019 Equity Incentive Plan (together, as amended, the “Plans”). The Plans are designed to promote the interests of the Company and its stockholders by enabling the Company to offer an opportunity to employees and consultants to receive grants of equity-based and cash-based incentive awards, so as to better attract, retain, and reward them, to align their interests with those of stockholders, and to provide them with an incentive for outstanding performance to generate superior returns to the Company’s stockholders. The Plan Amendments require the acceleration of all outstanding unvested stock awards prior to the consummation of a change in control of the Company, if such stock awards are not assumed by the surviving corporation or acquiring corporation (or its parent company) or substituted with similar awards for such outstanding stock awards. The Plan Amendments affect the terms applicable to awards granted under, or otherwise subject to the terms of, the Plans, enabling the Company to continue to use the Plans as critical tools to attract, motivate, reward, and retain key employees.

The foregoing summary description of the Plan Amendments are qualified in their entirety by reference to the actual terms of the Plan Amendments, copies of which are attached to this Current Report on Form 8-K as Exhibits 10.1 and 10.2, and are incorporated by reference into this Item 5.02.

Exhibit 99.1

Millendo Therapeutics Provides Corporate and Pipeline Update

– MLE-301, a selective neurokinin 3 receptor (NK3R) antagonist, advancing with first-in-human trials expected to initiate in 3Q20 –

– Further investment in nevanimibe for congenital adrenal hyperplasia (CAH) not planned following interim data review –

– Strategic evaluation in place to determine future corporate strategy –

ANN ARBOR, Mich., June 23, 2020 – Millendo Therapeutics, Inc. (Nasdaq: MLND), a biopharmaceutical company primarily focused on developing novel treatments for endocrine diseases with significant unmet needs, announced today that it has taken steps forward in its evaluation of strategic options to determine the company’s future direction. As part of these efforts, Millendo has engaged SVB Leerink to support the strategic review process. The company finished Q1 2020 with $58.9 million in cash, cash equivalents and restricted cash.

“Our board of directors and leadership team recognize the importance of conducting a comprehensive and strategic review. We are aligned in our focus on evaluating our pipeline and its potential, beginning with the advancement of MLE-301,” said Julia C. Owens, President and Chief Executive Officer of Millendo Therapeutics. “Our objective is to come away from this process with an actionable plan that leverages our assets, capital and capabilities in a way that maximizes shareholder value.”

MLE-301, a selective neurokinin 3 receptor (NK3R) antagonist, continues to advance to first-in-human trials: An IND has been filed to study MLE-301 for the treatment of vasomotor symptoms (VMS), also known as hot flashes and night sweats, in menopausal women. VMS currently impact 70% of peri/post-menopausal women, representing over 20 million women in the US. Phase 1 clinical studies are expected to initiate in 3Q20.

Interim review of nevanimibe open-label Phase 2b study in CAH completed: Results from 10 subjects, nine from cohort 1 and one from cohort 2, with at least 12 weeks of treatment with nevanimibe in this open-label, continuous dose escalation study showed that one patient (10%) met the primary endpoint of achieving 17- hydroxyprogesterone (17-OHP) levels less than or equal to 2-times the upper limit of normal (ULN). Treatment under the amended protocol with dose titration starting at 500 mg BID improved tolerability of nevanimibe. However, based on the observed level of nevanimibe activity and the changing competitive environment, no further investment in the program is currently planned.

About MLE-301
MLE-301 is a neurokinin 3 receptor (NK3R) antagonist that is being developed as a potential treatment of vasomotor symptoms (VMS), commonly known as hot flashes and night sweats, in menopausal women. NK3R plays a key role in regulating the activity of KNDy (kisspeptin/NKB/dynorphin) neurons, which are believed to participate in the generation of VMS. By inhibiting the NK3R signaling on the KNDy neurons and potentially other NK3R-expressing neurons that propagate heat dissipation signals through the hypothalamus, MLE-301 aims to reduce the effects of hyperactive KNDy neurons and thereby address vasomotor symptoms.

About Nevanimibe

Nevanimibe decreases adrenal steroidogenesis through the inhibition of acyl coenzyme A: cholesterol acyltransferase 1, or ACAT1, and is being studied for the treatment of classic congenital adrenal hyperplasia (CAH). CAH is a rare, monogenic adrenal disease that requires lifelong treatment with exogenous cortisol, often at high doses. These chronic high doses of cortisol can result in side effects that include diabetes, obesity, hypertension and psychological problems. An interim review of data from the Phase 2b trial of nevanimibe in CAH (NCT03669549) was conducted; results from 10 subjects with at least 12 weeks of treatment with nevanimibe in the open-label, continuous dose escalation study showed that one patient (10%) met the primary endpoint of achieving 17-hydroxyprogesterone (17-OHP) levels less than or equal to 2-times the upper limit of normal (ULN).

About Millendo Therapeutics, Inc.
Millendo Therapeutics is a biopharmaceutical company primarily focused on developing novel treatments for endocrine diseases where current therapies do not exist or are insufficient. Millendo seeks to create distinct and transformative treatments where there is a significant unmet medical need. The company is currently advancing MLE-301 for the treatment of vasomotor symptoms associated with menopause. For more information, please visit www.millendo.com.

The Market Is Looking to Break the Efficacy/Safety Trade-off Potential efficacy of estrogens without cancer and cardiovascular concerns MLE-301 • Estrogens demonstrate reduction in VMS frequency by ~80-90%, while SSRI efficacy is limited (~40-60%) – Estrogen replacement therapy was significant market, but plummeted upon Women’s Health Initiative (WHI) findings – WHI caused concerns of stroke, DVT and cancers resulting in black box warnings Efficacy • Women suffering from vasomotor symptoms want an effective non-hormonal option – Avoid concerns for cancer and CV risk – OTCs and SSRIs: insufficient hot flash control • NK3R antagonists including MLE-301 are positioned to potentially break the trade-off between efficacy and safety seen with estrogen therapy Safety 6 EstrogensMLE-301 SSRIs OTCs

NK3R is a Key Receptor on KNDy Neurons Overactive KNDy signaling in menopausal women is believed to lead to VMS MLE-301 • Estrogen is a negative regulator of KNDy neurons – Absence of estrogen-driven negative feedback following menopause causes KNDy neurons to become hypertrophic – Hyperactivity in KNDy neurons is believed to initiate the process that causes VMS – Inhibiting NK3R signaling seeks to restore normal functioning of heat dissipation effectors and to resolve the dysregulation KNDy neurons are overactive in menopausal women with VMS KNDy Neuron GnRH neuron ‘Heat dissipation’ neuron • KNDy neurons are implicated in the thermoregulatory pathway – NK3R antagonists can also impact Hypothalamic-Pituitary-Gonadal (HPG) axis Vasomotor Symptoms 7

NK3R is Implicated in Vasomotor Symptoms Administration of NKB induced VMS in 8/10 women MLE-301 • Robust genetic, pharmacodynamic, and clinical data support the role of NK3R in VMS NK3R Signaling Induces VMS in Women Human mutations in NK3R and its ligand NKB show defects in Hypothalamic-Pituitary-Gonadal (HPG) axis signaling Genomic studies have identified mutations associated with hot flashes in the NK3R gene locus Administration of NK3R ligand (NKB) results in hot flashes – – – 8

NK3R Antagonist Effects Are Comparable Clinical data has established class efficacy to Estrogen MLE-301 • Three different NK3R antagonists have been associated with reductions of hot flashes in clinical studies – MLE4901 (Millendo), NT-814 (KaNDy Therapeutics) and fezolinetant (Astellas) – Effects appear similar across the class, and similar to estrogen, but with more rapid onset of action •Reductions in hot flash frequency and severity observed by day 3 0 -20 -40 -60 • Elevated liver function tests (LFT) have been seen with two NK3R antagonist product candidates -80 Millendo terminated development of MLE4901 in 2017 due to LFT signal LFTs reported at higher doses of fezolinetant in Phase 2b study Unclear if LFTs are a class effect •NK3R not expressed in liver – – – -100 PlaceboNK3Ra Includes VMS clinical results for 3 different NK3R antagonists in orange (MLE4901 Phase 2a, fezolinetant Phase 2a and 2b, KaNDy’s NT-814 Phase 2a), and estrogen/HRT (blue) study. 9 % Change in HF Frequency from Baseline

MLE-301: NK3R Antagonism in Preclinical Studies MLE-301 • MLE-301 is a novel, potent, selective NK3R antagonist – Potential to demonstrate comparable vasomotor effects as other NK3R antagonist candidates – Over 25-45x as selective for NK3R vs NK1R/2R – As a chemically distinct molecule, MLE-301 is intended to avoid the LFT elevations seen with other NK3Rs • Preclinical data suggests MLE-301 engages target NK3R binding inhibition (IC50) is 25 nM >70% reduction in testosterone in canine study observed at higher doses •NK3R antagonism believed to impact both the HPG axis and the thermoregulatory pathway •Experience with MLE4901 suggests impacts are correlated – – 10
