| BOSTON, Nov. 11, 2021 /PRNewswire/ -- Stealth Biotherapeutics (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 three months ended September 30, 2021 and announced recent business highlights.
“We are excited to broaden our clinical development efforts with multiple new trial initiations expected over the coming months,” said Reenie McCarthy, Chief Executive Officer at Stealth. “We are highly enthusiastic about the potential of elamipretide to treat extrafoveal geographic atrophy ahead of our ReCLAIM-2 data read-out, which is expected during the first half of next year, and are increasingly optimistic about the feasibility of our intravitreal development efforts which we hope will support potential partnering discussions. While we are disappointed that the FDA declined to file our new drug application for Barth syndrome, despite the significant unmet need and the appeal from the patient community, we are looking forward to our meeting with the FDA later this quarter to discuss a potential path forward. We are also moving forward with our development efforts in several other rare disease indications, including our planned initiation of our NuPOWER Phase 3 clinical trial in patients with primary mitochondrial myopathy due to nuclear DNA mutations and our scheduled pre-IND meeting with DCN to discuss our development efforts in Duchenne muscular dystrophy. We’re also thrilled to be bringing SBT-272, which is the cornerstone of our growing neurology franchise, back into the clinic in a Phase 1 clinical trial expected to start early next year.” Third Quarter 2021 and Recent Highlights Ophthalmology franchise. ReCLAIM-2 in extrafoveal geographic atrophy. The Company presented data from its ophthalmology clinical trials at recent conferences, including EURETINA 2021 Virtual Congress, the Annual Scientific Session of The Retina Society, and the American Society of Retina Specialist (ASRS) Annual Scientific Meeting. These data included analyses from the Company’s Phase 1 ReCLAIM clinical trial demonstrating that elamipretide-mediated improvement of visual function was significantly associated with baseline retinal mitochondrial health and baseline patient characteristics from the Company’s fully-enrolled ReCLAIM-2 clinical trial. The Company expects to announce top-line clinical trial results from ReCLAIM-2 during the first half of 2022. Cardiomyopathy franchise. Barth syndrome. In August 2021, the Company submitted its new drug application (NDA) for Barth syndrome, for which it received a Refusal to File letter from the FDA in October 2021. The Company requested and the FDA granted a Type A meeting with DCN to discuss why SPIBA-001, the Company’s positive Phase 3 trial comparing SPIBA-201 results to a retrospective natural history control and the primary basis for the NDA submission, was not sufficient to support the filing of the NDA. At the meeting, which is scheduled for later this quarter, the Company also plans to propose alternative steps to generate additional evidence of elamipretide’s effectiveness in Barth syndrome and hopes to reach agreement with DCN on a viable path forward. Duchenne muscular dystrophy (DMD). In September 2021, the Company presented positive elamipretide data showing improvements in mitochondrial respiration and heart muscle function in explanted tissue from failing pediatric human hearts at the International Society for Heart Research North American Section Meeting 2021. The study also demonstrated that elamipretide treatment improved mitochondrial respiration, contraction and relaxation in muscle fibers isolated from failing hearts of children with dilated cardiomyopathy. The lead author of the study indicated that these data were consistent with observed effects of elamipretide in metabolic (muscular dystrophy) cardiomyopathy. In October 2021, the Company’s request for a pre-IND meeting to discuss its DMD development plan was granted by DCN, and a meeting is scheduled for later this year. Friedreich’s ataxia. The investigator is awaiting Institutional Review Board approval of the planned Phase 2a clinical trial in patients with Friedreich’s ataxia and expects to begin enrollment in early 2022. Neurology franchise. NuPOWER initiation. In July 2021, the Company reached alignment with Division of Rare Diseases and Medical Genetics on the design of NuPOWER, its planned Phase 3 clinical trial in patients with mitochondrial disease associated with pathogenic nDNA mutations (nPMM). Trial initiation is expected by year-end. SBT-272. In October 2021, the Company announced that promising data from a study evaluating the effects of SBT-272 in a murine model of amyotrophic lateral sclerosis (ALS) were presented at the virtual 2021 Annual Northeast Amyotrophic Lateral Sclerosis (NEALS) Meeting. The study demonstrated that sustained SBT-272 levels across different regions of the brain protected mitochondria against ischemic stress. In primary motor neuron cultures, treatment with SBT-272 improved mitochondrial motility in a dose-dependent manner, reduced mitochondrial ultrastructural defects and was associated with improved axon outgrowth. In September 2021, the Company announced that promising data from a study evaluating the effects of SBT-272 in a murine model of Parkinson’s disease were presented at the International Parkinson and Movement Disorder Society Virtual Congress 2021. Systemic daily administration of SBT-272 doses significantly protected against the loss of dopaminergic neurons and the aggregation of pathological alpha-synuclein and reduced two markers of neuroinflammation in this model. Financial updates In September 2021, the Company and its wholly owned subsidiary, Stealth BioTherapeutics Inc., entered into a Venture Loan and Security Agreement (“LSA”) with Horizon Technology Finance Corporation and Powerscourt Investments XXV, LP, which provided the Company and its subsidiary with a senior secured credit facility in an aggregate principal amount of $25.0 million. On September 30, 2021, upon the closing of the LSA, $15.0 million was drawn by the Company, of which approximately $5.7 million was utilized to payoff the existing term loan with Hercules Capital, Inc. The additional $10 million available under the LSA may be funded upon the achievement of a predetermined milestone. In September 2021, the Company received $11.0 million under the Development Funding Agreement with Morningside Venture (I) Investments Limited (“Morningside”). Key Upcoming Milestones
Financial Results for the three months ended September 30, 2021 Cash Position: Cash and cash equivalents were $42.3 million at September 30, 2021, compared to $32.8 million at December 31, 2020. In September 2021, the Company received $11.0 million of the remaining $27.0 million total due during the second half of 2021 from Morningside under the Development Funding Agreement, which includes the $5.0 million milestone payable upon Barth NDA submission and the $22.0 million balance that was committed as additional financing in May 2021. In October 2021, the Company received $5.0 million of the additional financing, and expects to receive the remaining $11.0 million on or around December 1, 2021. The Company expects that its cash, cash equivalents and investments as of September 30, 2021, together with the $5.0 million of additional financing received in October and $11.0 million of additional financing expected in December will be sufficient to enable it to fund its planned operations into the third quarter of 2022. Research and Development (R&D) Expenses: R&D expenses were $6.7 million for the three months ended September 30, 2021, compared to $6.2 million for the same period in 2020. The increase was due to a $1.2 million increase in preclinical costs to develop and expand our current pipeline, an increase of $0.6 million in headcount and related costs, and an increase of $0.1 million in manufacturing costs, offset by a net decrease of $1.4 million in clinical costs primarily driven by the closeout of the MMPOWER-3 clinical trial. General and Administrative (G&A) Expenses: G&A expenses were unchanged at $4.7 million for the three months ended September 30, 2021 and for the same period in 2020. For the three months ended September 30, 2021, there was an increase of $0.3 million in pre-commercial costs offset by a $0.2 million decrease in facility related costs and a $0.1 million decrease in costs of professional services. Other Income (Expense): Other income was $5.1 million for the three months ended September 30, 2021, compared to other expense of $0.3 million for the same period in 2020. Other income in 2021 consisted of a $5.4 million gain due to the change in fair value of the derivative liability, offset by a $0.1 million loss due to extinguishment of the Hercules term loan and $0.2 million in interest expense. Other expense in 2020 consisted of $0.3 million in interest expense. Net Loss: Net loss was $6.3 million, or $0.01 basic and diluted net loss per ordinary share, for the three months ended September 30, 2021, as compared to $11.2 million, or $0.02 basic and diluted net loss per ordinary share, for the same period in 2020.

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 and are involved in many common age-related diseases, typically involving organ systems with high energy demands such as the heart, the eye, and the brain. We believe our lead product candidate, elamipretide, has the potential to treat both rare metabolic cardiomyopathies, such as Barth syndrome, DMD and Friedreich’s ataxia, rare mitochondrial diseases entailing nuclear DNA mutations, as well as ophthalmic diseases entailing mitochondrial dysfunction, such as dry age-related macular degeneration and Leber’s hereditary optic neuropathy. We are evaluating our second-generation clinical-stage candidate, SBT-272, and our new series of small molecules, SBT-550, for rare neurological disease indications following promising preclinical data. We have optimized our discovery platform to identify novel mitochondria-targeted compounds which may be nominated as therapeutic product candidates or utilized as mitochondria-targeted vectors to deliver other compounds to mitochondria.
