Millendo Therapeutics Reports First Quarter 2019 Operating and Financial Results

Millendo
Therapeutics, Inc. (Nasdaq:MLND), a clinical-stage biopharmaceutical
company developing novel treatments for orphan endocrine diseases, today
provided a corporate update and reported financial results for the first
quarter 2019 ended March 31, 2019.

“Our first quarter accomplishments represent important progress toward
the achievement of our strategic priorities for 2019, including the
initiation of our ZEPHYR pivotal Phase 2b/3 clinical trial in PWS
patients, which has the potential to support an NDA submission for
livoletide,” said Julia C. Owens, President and Chief Executive Officer
of Millendo Therapeutics. “Furthermore, we presented on both trials for
our late stage clinical candidates, livoletide and nevanimibe, at ENDO
and established the foundation for a commercial organization in the
Boston area, ahead of topline data for livoletide in the first half of
next year. We look forward to continuing to make important strides for
patients, families and caregivers throughout 2019.”

First Quarter 2019 and Recent Highlights

• Initiated ZEPHYR, a Pivotal Phase 2b/3 Clinical Trial of Livoletide
  in PWS Patients: In March 2019, Millendo initiated the ZEPHYR
  trial, which has the potential to support a New Drug Application (NDA)
  submission. Topline data from the Phase 2b portion of the study is
  expected in 1H20.
• Initiated Development of a Pen Delivery System for Livoletide: Millendo
  has initiated pre-clinical activities in support of the development of
  a multi-dose pen device to improve patient and caregiver convenience
  and further simplify administration of livoletide.
• Protocol Amendment for Nevanimibe Phase 2b Study in CAH Underway:
  Preliminary data with a starting dose of 1000 mg BID showed lower
  tolerability than expected based on prior clinical experience with the
  drug. Enrollment will be paused while a protocol amendment is
  submitted to add a lower starting dose. Patients currently enrolled in
  the study will continue per protocol and may dose escalate as planned.
• Delivered Multiple Presentations at ENDO 2019: In March,
  Millendo presented three posters at ENDO 2019, including an overview
  of the study design for ZEPHYR, data from the livoletide nonclinical
  safety program, and an overview of the ongoing nevanimibe Phase 2b
  study in CAH.
• Initiated Building a Commercial Organization in the Boston area:
  In April, Millendo entered into a lease for offices in Lexington, MA,
  and has begun to establish a commercial organization to help prepare
  for potential future product launch.

First Quarter 2019 Financial Results

Cash Position: Cash, cash equivalents and marketable securities
were $67.0 million at March 31, 2019, compared to $77.7 million at
December 31, 2018.

Research and Development (R&D) Expenses: R&D expenses were
$6.2 million for the first quarter 2019, as compared to $2.8 million for
the same period in 2018. The increase in R&D expenses was primarily
driven by increased spending on the company’s Phase 2b/3 pivotal study
of livoletide in PWS and higher employee compensation costs due to
increased headcount.

General and Administrative (G&A) Expenses: G&A expenses were
$4.5 million for the first quarter 2019, as compared to $1.6 million for
the same period in 2018. The increase in G&A expenses was primarily
driven by increased costs related to employee compensation and
professional fees to support ongoing business operations and compliance
with obligations associated with being a publicly traded company.

Net Loss: The company’s net loss for the quarter ended March 31,
2019 was $10.4 million as compared to $4.4 million for the same period
in 2018.

2019 Financial Guidance

Millendo expects that its cash, cash equivalents, and marketable
securities will support the company’s capital needs into the second half
of 2020, beyond the readout for the topline results of the Phase 2b
portion of the Phase 2b/3 pivotal study of livoletide in PWS, which is
expected in the first half of 2020. This cash runway guidance is based
on the company’s current operational plans and excludes any additional
funding or business development activities.

About Livoletide
Millendo’s lead asset, livoletide, is an
unacylated ghrelin analogue in late stage clinical development for the
treatment of Prader-Willi syndrome (PWS), a rare genetic disease
characterized by hyperphagia, a chronic unrelenting hunger, that leads
to obesity, metabolic dysfunction, reduced quality of life and early
mortality. In March 2019, the company initiated a pivotal Phase 2b/3
clinical study of livoletide in patients with PWS. In a previous
randomized, double-blind, placebo-controlled Phase 2 clinical trial in
47 patients with PWS, administration of livoletide once daily was
associated with a clinically meaningful improvement in hyperphagia, as
well as a reduction in appetite. Millendo has received orphan drug
designation for livoletide from the U.S. Food and Drug Administration
(FDA) and the European Medicines Agency (EMA) for the treatment of PWS.

(ZEPHYR) please visit www.clinicaltrials.gov
(NCT03790865)
or the Patients
and Families portion of our website.

About Nevanimibe
Nevanimibe decreases adrenal
steroidogenesis through the inhibition of ACAT1 and is being studied for
the treatment of two orphan adrenal diseases: classic congenital adrenal
hyperplasia (CAH) and endogenous Cushing’s syndrome (CS). CAH is a rare,
monogenic adrenal disease that requires lifelong treatment with
exogenous cortisol, often at high doses, which can make it difficult for
physicians to appropriately treat CAH without causing adverse
consequences. Millendo has received orphan drug designation for
nevanimibe for the treatment of CAH and CS from the FDA, as well as from
the EMA for the treatment of CAH. In a Phase 2 proof-of-concept clinical
trial in patients with CAH, Millendo observed nevanimibe to be
associated with clear signs of clinical activity in seven of 10 treated
patients. A Phase 2b trial of nevanimibe in CAH (NCT03669549)
is active with enrollment currently paused as described above, and a
Phase 2 trial of nevanimibe in CS (NCT03053271)
is ongoing.
