ANN ARBOR, Mich.–(BUSINESS WIRE)–Millendo Therapeutics, Inc. (Nasdaq: MLND), a clinical-stage biopharmaceutical company primarily focused on developing novel treatments for orphan endocrine diseases with significant unmet needs, today provided a corporate update and reported financial results for the quarter ended September 30, 2019.

“With the Phase 2b portion of our ZEPHYR pivotal Phase 2b/3 clinical study of livoletide in PWS patients now fully recruited for patients ages 8 to 65, we look forward to reporting topline results in the first half of 2020,” said Julia C. Owens, President and Chief Executive Officer of Millendo Therapeutics. “We are excited about the potential for livoletide to treat hyperphagia and other food-seeking behaviors that lead to morbidity and mortality in these patients, as well as significant caregiver burden.

“In addition, our Phase 2b clinical study of nevanimibe in CAH is continuing recruitment across its two cohorts, providing us with further insights on the activity of nevanimibe over longer treatment periods and in CAH patients where steroid doses are reduced. We expect to report topline results from the study’s first cohort in the second half of 2020.”

Third Quarter 2019 and Recent Highlights

• Patient recruitment completed for the Phase 2b portion of ZEPHYR for patients ages 8 to 65, eight months after study initiation, with topline results expected in 1H20. This study, one of the largest PWS studies ever conducted with over 150 patients recruited across 38 clinical trial sites worldwide, is evaluating the safety and efficacy of livoletide on hyperphagia and food-related behaviors in patients with Prader-Willi syndrome. The study’s primary endpoint measures the change in hyperphagia and other food-related behaviors using the validated Hyperphagia Questionnaire for Clinical Trials (HQ-CT). Secondary outcome measures include body weight, fat mass and waist circumference. Millendo continues to implement a protocol amendment globally adding an additional cohort of PWS patients ages 4 to 7. Sites that recruit pediatric patients will continue to actively recruit patients for this cohort.

• Millendo is hosting a PWS breakfast symposium on November 14 in New York City. Shawn McCandless, M.D., Professor and Head of Section, Genetics and Metabolism – Department of Pediatrics, University of Colorado School of Medicine and Children’s Hospital of Colorado and company management will discuss the epidemiology of the disease, the current treatment landscape and the opportunity for livoletide.

• Topline results from the ongoing Phase 2b study of nevanimibe in patients with CAH are anticipated for cohort 1 in 2H20. The Phase 2b study will evaluate nevanimibe’s efficacy and safety in treating CAH and includes two distinct cohorts of patients. Cohort 1 includes patients with a baseline 17-hydroxyprogesterone (17-OHP) level, a key measure of disease control, of greater than or equal to 4-times the upper limit of normal (ULN) which is similar to the Phase 2a study population but now with longer duration of treatment and with the ability for additional dose-ranging. Cohort 2 includes patients with elevated glucocorticoids and a baseline 17-OHP level of less than 4-times the ULN. Patients in cohort 2 will first have their glucocorticoid dose reduced, with an anticipated increase in 17-OHP levels and then treatment with nevanimibe seeking to reduce the 17-OHP levels. The study’s primary endpoint across both study cohorts is an assessment of the percentage of patients that achieve 17-OHP levels of less than or equal to 2-times the ULN. Secondary endpoints include assessments of other adrenal hormones, including androgens.

Third Quarter 2019 Financial Results

Cash Position: Cash, cash equivalents, marketable securities and restricted cash were $48.3 million at September 30, 2019, compared to $78.2 million at December 31, 2018.

Research and Development (R&D) Expenses: R&D expenses were $7.3 million for the third quarter of 2019, as compared to $3.9 million for the same period in 2018. The increase in R&D expenses was primarily driven by increased spending on the company’s pivotal Phase 2b/3 study of livoletide in PWS and higher compensation expenses as a result of increased headcount.

General and Administrative (G&A) Expenses: G&A expenses were $4.4 million for the third quarter of 2019, as compared to $3.9 million for the same period in 2018. The increase in G&A expenses was primarily driven by higher compensation expense as a result of increased headcount and increased expenses to support ongoing business operations and obligations associated with being a publicly traded company.

Net Loss: The company’s net loss for the quarter ended September 30, 2019 was $11.6 million as compared to $7.9 million for the same period in 2018.

2019 Financial Guidance

Millendo expects that its cash, cash equivalents, marketable securities and restricted cash will support the company’s capital needs through the fourth quarter of 2020, beyond the readout for the topline results of the Phase 2b portion of the pivotal Phase 2b/3 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

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 a previous randomized, double-blind, placebo-controlled Phase 2 clinical trial in 47 patients with PWS, administration of livoletide once daily for two weeks was associated with a clinically meaningful improvement in hyperphagia, as well as a reduction in appetite. Millendo has received both Orphan Drug Designation and Fast Track Designation for livoletide for the treatment of PWS from the U.S. Food and Drug Administration (FDA) and Orphan Drug Designation from the European Medicines Agency (EMA). For more information about Millendo’s pivotal study of livoletide (ZEPHYR) please visit www.clinicaltrials.gov (NCT03790865) or the Patients and Families portion of our website.

About the ZEPHYR study

The ZEPHYR study is a two-part, randomized, double-blind, placebo-controlled pivotal Phase 2b/3 study. The first part is a Phase 2b study that includes a three-month double-blind, placebo-controlled core period in which patients receive one of two doses of livoletide or placebo followed by a nine-month extension period in which all patients receive livoletide. The Phase 2b portion of the study, one of the largest global PWS studies ever conducted, has completed recruitment for patients ages 8 to 65 with over 150 patients across 38 clinical sites in the United States, Europe and Australia. Millendo continues to implement a protocol amendment globally adding an additional cohort of PWS patients ages four to seven. Sites that recruit pediatric patients will continue to actively recruit patients for this cohort. The second part is a Phase 3 study that will consist of a six-month double-blind, placebo-controlled core period in which patients will receive livoletide or placebo followed by a six-month extension period in which all patients receive livoletide. The study’s primary endpoint measures the change in food-related behaviors using the validated Hyperphagia Questionnaire for Clinical Trials (HQ-CT) during each core period. ZEPHYR is a pivotal study and the results of the Phase 2b portion of the study may be sufficient to support a new drug application (NDA) for livoletide.

About Nevanimibe

Nevanimibe decreases adrenal steroidogenesis through the inhibition of 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, which can make it difficult for physicians to appropriately treat CAH without causing adverse consequences. 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 ongoing.
