November 14, 2019

BOSTON, Nov. 14, 2019 /PRNewswire/ -- Stealth BioTherapeutics Corp (NASDAQ: MITO), a clinical-stage biotechnology company focused on the discovery, development and commercialization of novel therapies for diseases involving mitochondrial dysfunction, today reported financial results for the third quarter ended September 30, 2019 and provided a corporate update.

"We're approaching a transformational stage in our company's development, with our recently announced partnership with Alexion and our anticipated pivotal data in primary mitochondrial myopathy in January bringing us even closer toward our goal of delivering transformative therapies to patients with rare, mitochondrial diseases," said Reenie McCarthy, Stealth's Chief Executive Officer. "On the clinical front, the long-term data from our Barth open-label extension, now showing improvement across multiple parameters of cardiac function suggestive of cardiac remodeling, increases our optimism in elamipretide as a potential therapy for this devastating disease.  We're also excited to usher our new investigational candidate, SBT-272, into the clinic, following recently announced data in an ALS model highlighting its neuro-protective potential."

Recent Highlights

  • Entered an option agreement with Alexion to co-develop and commercialize the subcutaneous formulation of lead product candidate, elamipretide, which is currently in a Phase 3 study in primary mitochondrial myopathy (PMM). If exercised, the parties will enter into a 50-50 co-development and co-promote in the U.S. and Alexion will receive exclusive rights to develop and commercialize subcutaneous elamipretide outside the U.S. In October, Stealth received an initial payment of $30 million from Alexion for an equity investment, an option fee and development funding, and is entitled to receive additional option-related and milestone-dependent payments upon option exercise. Stealth has retained rights to develop all other pipeline product candidates, including SBT-272, which is poised to enter Phase 1 by year-end.
  • Presented new data from the open-label extension portion of the Phase 2/3 TAZPOWER trial at the American Society of Human Genetics (ASHG) 2019 Annual Meeting in Houston, Texas. Data from 10 patients with Barth syndrome on the open-label extension showed a statistically significant (p<0.05) increase in average cardiac stroke volume, a primary determinant of cardiac output and overall heart function, from baseline to week 36 of the open-label extension.
  • Presented new preclinical data for SBT-272 at the 18th Annual Northeast Amyotrophic Lateral Sclerosis Consortium. Data from a mouse model of amyotrophic lateral sclerosis (ALS) demonstrated a statistically significant, dose-dependent delay in the onset of neurological symptoms as well as a reduction in neurofilament light chain, a systemic marker of neurodegeneration, and prolonged lifespan. SBT-272 is currently in pre-clinical development for treatment of ALS and other rare neurodegenerative diseases involving mitochondrial dysfunction and is expected to advance into Phase 1 by year-end.

Key Upcoming Milestones

  • FDA submission of Phase 3 protocol for elamipretide in Leber's hereditary optic neuropathy (LHON) by year-end.
  • Initiation of Phase 1 clinical trial of new pipeline candidate, SBT-272, by year-end.
  • Reporting top-line data from MMPOWER-3, a Phase 3 clinical trial of elamipretide in PMM, in January 2020.
  • Completing enrollment of Phase 2b clinical trial in geographic atrophy (GA) associated with dry age-related macular degeneration in first part of 2020.
  • FDA end-of-phase meeting for Barth syndrome in first part of 2020.

Financial Results for the Quarter Ended September 30, 2019

Cash Position: Cash and cash equivalents were $37.2 million at September 30, 2019.   In October 2019, we received a $30 million payment associated with the Alexion option and share purchase agreements announced on October 10, 2019.

Research and Development (R&D) Expenses:

R&D expenses were $9.8 million for the three months ended September 30, 2019, compared to $16.2 million for the same period in 2018. The decrease was primarily due to a $3.4 million net decrease in clinical trial costs due to timing of trials that ended in 2018, a $0.4 million decrease in discovery related expenses due to timing of activities and a $3.4 million decrease in contract manufacturing, offset in part by an increase of $0.8 million in employee and consultant related costs.

General and Administrative (G&A) Expenses:

G&A expenses were $6.3 million for the three months ended September 30, 2019, compared to $4.8 million for the same period in 2018. The increase in administrative expenses was primarily attributed to an increase of $0.6 million in employee and consultant related costs, associated in part with build-out of the pre-commercialization and compliance functions, $0.5 million in professional services for activities attributable to operating as a public company and $0.4 million in pre-commercial activities including building disease awareness.

Other Expense, Net:

Other expense was $0.4 million for the three months ended September 30, 2019, compared to $1.7 million for the same period in 2018. The decrease in other expense is primarily attributed to a $5.5 million decrease in interest expense related to convertible debt which was converted into ordinary shares in conjunction with our initial public offering, an increase in interest income of $0.1 million, offset in part by a $4.3 million change in period over period fair value adjustments of the derivative liability associated with the convertible debt.

Net Loss: 

Net loss was $16.5 million, or $0.04 basic and diluted net loss per ordinary share for the three months ended September 30, 2019, as compared to $22.7 million, or $0.33 basic and diluted net loss per ordinary share for the same period in 2018.

About Stealth

We are a clinical-stage biotechnology company focused on the discovery, development and commercialization of novel therapies for diseases involving mitochondrial dysfunction. Mitochondria, found in nearly every cell in the body, are the body's main source of energy production and are critical for normal organ function. Dysfunctional mitochondria characterize a number of rare genetic diseases, collectively known as primary mitochondrial diseases, and are also involved in many common age-related diseases. We believe our lead product candidate, elamipretide, as well as pipeline candidates including SBT-272, have the potential to treat both rare genetic and common age-related mitochondrial diseases. We are studying elamipretide in primary mitochondrial myopathy, Barth syndrome and Leber's hereditary optic neuropathy, which are rare genetic diseases. We are also studying elamipretide in geographic atrophy associated with dry age-related macular degeneration. Our pipeline candidates include SBT-272, which we are evaluating for rare neurodegenerative disease indications, and SBT-20 and SBT-259, which we are evaluating for rare peripheral neuropathies. We have optimized our discovery platform to identify novel mitochondrial-targeted compounds, which may be nominated as therapeutic product candidates or utilized as scaffolds to deliver other compounds to mitochondria. We have assembled a highly experienced management team, board of directors and group of scientific advisors to help us achieve our mission of leading mitochondrial medicine.
