BOSTON, April 4, 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 year ended December 31, 2018 and announced recent business highlights.
"In 2018, we executed across multiple clinical, preclinical and regulatory milestones, augmenting our leading role in the development of mitochondrial medicine. We made significant strides toward enrolling our pivotal study in primary mitochondrial myopathy; announced data from our trials in dry AMD, Barth syndrome and Leber's hereditary optic neuropathy; initiated IND-enabling studies for the first of our new pipeline compounds; and secured Orphan Drug designation for elamipretide for the treatment of Barth syndrome and Leber's hereditary optic neuropathy and Fast Track designation for elamipretide for the treatment of dry AMD with geographic atrophy," said Reenie McCarthy, Chief Executive Officer at Stealth. "We're continuing the momentum into 2019, with the first patient now enrolled in our Phase 2b study in dry AMD with geographic atrophy, key regulatory interactions for Barth syndrome and Leber's hereditary optic neuropathy on our near-term horizon, and anticipated read-out of our pivotal primary mitochondrial myopathy trial by year end. The completion of our initial public offering earlier this year provides us with the financial strength to execute on our key clinical trials, data read-outs and regulatory interactions in the months ahead."
Fourth Quarter 2018 and Recent Highlights
- Dosed first patient in Phase 2b study of elamipretide in patients with dry age-related macular degeneration (dry AMD) with geographic atrophy. ReCLAIM-2, a Phase 2b, randomized, double-masked, placebo-controlled clinical study, will evaluate the safety and efficacy of subcutaneous injections of elamipretide in 180 patients with dry AMD with geographic atrophy. Full enrollment is targeted by early 2020.
- Completed initial public offering (IPO). We completed our IPO of 7,088,232 American Depositary Shares (ADSs) at a public offering price of $12.00 per ADS, which includes a partial exercise of the underwriters' over-allotment option. The total gross proceeds, before deducting underwriting discounts and commissions and other offering expenses, were approximately $85.1 million.
- Granted Fast Track designation for elamipretide for the treatment of dry AMD with geographic atrophy in November 2018. The FDA's Fast Track program facilitates the development and review of drugs to treat serious conditions with unmet medical needs. Elamipretide has also been granted Fast Track designation for the treatment of primary mitochondrial myopathy, Barth syndrome and Leber's hereditary optic neuropathy, three rare primary mitochondrial diseases.
Key Upcoming Milestones
- Meet with FDA in the first half of 2019 to discuss regulatory path for elamipretide in Barth's syndrome
- Mid-year meeting with FDA to discuss regulatory path for elamipretide in Leber's hereditary optic neuropathy
- Report top-line data from Phase 3 clinical trial in primary mitochondrial myopathy by the end of 2019
- Initiate Phase 1 clinical trial of new pipeline candidate, SBT-272, by the end of 2019
2018 Financial Results
Research and Development (R&D) Expenses: R&D expenses were $53.1 million for fiscal year 2018, compared to $63.2 million for fiscal year 2017. This decrease was primarily due to a $10.4 million decrease in clinical trial costs, as our cardiovascular clinical trials ended during early 2018, offset by an increase in costs of approximately $1.3 million for our primary mitochondrial myopathy studies, for which we incurred expenses for a full year in 2018.
General and Administrative (G&A) Expenses: G&A expenses were $22.2 million for fiscal year 2018, compared to $16.5 million for fiscal year 2017. The increase in administrative expenses was primarily attributable to an increase of $5.1 million in financing costs and an increase in legal intellectual property costs of $0.6 million.
Net Loss: Net loss for the year ended December 31, 2018 was $96.7 million, or $1.41 basic and diluted net loss per ordinary share, as compared to $82.9 million for the year ended December 31, 2017, or $1.21 basic and diluted net loss per ordinary share.
Cash Position: Cash and cash equivalents were $10.9 million at December 31, 2018, compared to $4.1 million at December 31, 2017. In February and March 2019, Stealth raised $85.1 million of gross proceeds from its initial public offering.
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, has the potential to treat both rare genetic and common age-related mitochondrial diseases. We are studying elamipretide in the following primary mitochondrial diseases: primary mitochondrial myopathy, Barth syndrome and Leber's hereditary optic neuropathy. We are also studying elamipretide in dry AMD. Our other pipeline candidates include SBT-272, which we are evaluating for rare neurodegenerative disease indications, and SBT-20, 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.
