Millendo Therapeutics Announces Successful Merger Completion

Millendo Therapeutics, Inc. (Nasdaq:MLND), a clinical-stage biopharmaceutical company focused on developing novel treatments for orphan endocrine diseases, today announced that the proposed merger with OvaScience, Inc. has closed, following the approval of OvaScience’s stockholders received on December 4, 2018. The combined company will operate under the name Millendo Therapeutics and will focus on the further development of Millendo’s leading orphan endocrine pipeline, including livoletide, a potential first-in-class treatment for Prader-Willi syndrome (PWS), which Millendo expects will enter a pivotal Phase 2b/3 trial in the first quarter of 2019, and nevanimibe, which is in Phase 2b clinical development for the treatment of classic congenital adrenal hyperplasia (CAH). Millendo shares will continue to trade on the Nasdaq Capital Market under OvaScience’s ticker symbol “OVAS” on Friday, December 7, 2018, and, during such time, Nasdaq share numbers will not reflect the one-for-fifteen reverse split that occurred on December 6, 2018. Millendo Therapeutics shares will commence trading on the Nasdaq Capital Market under the new ticker symbol “MLND” and will reflect the one-for-fifteen reverse split in trading on Monday, December 10, 2018.

“The closing of the merger and concurrent financing represents a significant opportunity and milestone for Millendo, as we can now accelerate our work to bring life-changing therapies to market for rare endocrine diseases. We have two differentiated, late-stage endocrine therapies that have been observed to be well tolerated, and we believe address areas of significant unmet need,” said Julia C. Owens, Ph.D., President and Chief Executive Officer of Millendo. “In September 2018, we initiated our Phase 2b trial of nevanimibe in CAH, and we look forward to the planned initiation of our pivotal Phase 2b/3 trial of livoletide for PWS in the first quarter of 2019.”

Millendo has received total proceeds of $85.4 million, which includes $35.9 million in net cash from OvaScience and $49.5 million from an associated financing. Investors participating in the financing include Great Point Partners, New Enterprise Associates, Frazier Healthcare Partners, and Roche Venture Fund, among others. Jefferies and Leerink Partners acted as Joint Placement Agents for the Millendo financing.

Dr. Owens continued, “Millendo now has a strong balance sheet and sufficient cash runway to support our operations beyond anticipated results from both trials in the first half of 2020 – the three month placebo-controlled portion of our pivotal Phase 2b/3 trial of livoletide in PWS and our Phase 2b clinical trial of nevanimibe in CAH.”

In connection with the closing of the merger, OvaScience completed a one-for-fifteen reverse stock split. As a result of the reverse stock split, every fifteen shares of OvaScience common stock outstanding immediately prior to the merger was combined and reclassified into one share of OvaScience common stock. No fractional shares are being issued in connection with the reverse stock split. Instead of fractional shares, cash will be issued based on the closing price of OvaScience common stock on the Nasdaq Capital Market on December 4, 2018.

As a result of the closing of the merger, Millendo stockholders and option holders own or have rights to acquire 63.3% of the combined company, and former OvaScience stockholders will own 16.5% of the combined company. Investors participating in the associated financing will own 20.2% of the combined company.

The combined company will operate under the leadership of Millendo’s President and Chief Executive Officer, Julia Owens, and will be headquartered in Ann Arbor, Michigan. The board of directors is comprised of eight members, including Carol Gallagher, Pharm. D., Habib Dable, Mary Lynne Hedley, Ph.D., James Hindman, John Howe, M.D., Carole Nuechterlein, J.D., Julia Owens, Ph.D., and Randall Whitcomb, M.D. Dr. Gallagher is the new Chairman of the board of directors.

About Millendo’s Lead Programs
Millendo’s lead asset, livoletide, is an unacylated ghrelin analogue being developed 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 a randomized, double-blind, placebo-controlled Phase 2 clinical trial in 47 patients with PWS, Millendo observed that 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, or FDA, and the European Medicines Agency, or EMA, for the treatment of PWS. Millendo expects to initiate a pivotal Phase 2b/3 clinical trial of livoletide in PWS patients in the first quarter of 2019.

Millendo is also developing nevanimibe, an ACAT1 inhibitor 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. Nevanimibe has received orphan drug designation from the FDA for the treatment of CAH and CS, as well as from the EMA for the treatment of CAH. In a Phase 2 proof-of-concept clinical trial, Millendo observed nevanimibe to be associated with clear signs of clinical activity in seven of 10 treated patients and was reported to be well tolerated at all dose levels. Millendo initiated the Phase 2b trial of nevanimibe in CAH in September 2018. A Phase 2 trial of nevanimibe for the treatment of patients with CS is ongoing at clinical sites in the United States and United Kingdom.
