| BOSTON, Aug. 5, 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 June 30, 2021 and announced recent business highlights.
“We continue to make important progress on developing elamipretide and our deep pipeline of novel mitochondrial-targeted compounds to address rare and devastating diseases of mitochondrial dysfunction,” said Reenie McCarthy, Chief Executive Officer at Stealth. “On the regulatory front, we have decided to submit our NDA for Barth syndrome this month, in keeping with our commitment to the Barth syndrome community, members of which recently met with the FDA to educate the Agency about the community’s willingness to accept some degree of uncertainty of clinical benefit in considering treatment options for their ultra-rare and serious disease. We are also pleased to have reached alignment with DRDMG regarding our Phase 3 trial for patients with nPMD who responded to therapy in our previous primary mitochondrial myopathy trial. We are continuing to progress work on an intravitreal formulation for geographic atrophy ahead of Phase 2 data read-out early next year and to expand our clinical and preclinical development efforts in Friedreich’s ataxia, cardiomyopathy associated with Duchenne muscular dystrophy, and our burgeoning neurology franchise.” Second Quarter 2021 and Recent Highlights Barth syndrome. The Company has had multiple recent communications with senior Food and Drug Administration (FDA) officials at the Office of Cardiology, Hematology, Endocrinology and Nephrology and at the Division of Cardiology and Nephrology (DCN) regarding its Barth syndrome program following the April 2021 meeting during which DCN recommended another Phase 3 trial in which eligible patients remaining in open label extension (OLE) and additional patients would be randomized to elamipretide or placebo until a minimum number of clinical events occur (i.e., events leading to treatment failure). After further considering this recommendation, FDA advised that additional clinical trial data from the patients remaining on OLE is unlikely to add meaningfully to the evidence to support an NDA. Due to the ultra-rare nature of Barth syndrome, neither the Company nor the FDA to date has been able to identify a feasible trial design to generate additional data, and the Company has accordingly decided to submit its NDA. The NDA will include data from the SPIBA-001 Phase 3 Retrospective Natural History Control Trial, which met its primary and most secondary endpoints. The NDA will also include data from the TAZPOWER Phase 2/3 Clinical Trial, in which short-term therapy during the double-blind placebo-controlled crossover portion of the trial, despite not meeting the primary endpoints, resulted in improvements in metabolites that have been associated with clinical outcomes in chronic heart failure, and in which long-term therapy during OLE showed significant improvements in echocardiographic measures of cardiac function. The Company considers these data reasonably likely to predict improvements in morbidity or mortality. Long term therapy also improved clinical endpoints including exercise tolerance, strength, and physician- and patient- reported outcomes, as well as biomarker endpoints diagnostic of the disease. FDA has advised the Company that it does not believe the existing clinical data would support NDA review. The Company believes the data could support NDA review and approval on either an accelerated or full basis, although there can be no assurance that the FDA will file the NDA. Under the Development Funding Agreement announced in November 2020, the Company is entitled to receive an additional $5 million milestone payment upon Barth NDA submission.
Financial updates. In April 2021, the Company amended its Term Loan Facility with Hercules Capital, Inc. to defer ongoing amortization payments and extend the maturity until January 2022. In May 2021, the Company announced additional commitments of $30.0 million under the Development Funding Agreement with Morningside Venture (I) Investments Limited (“Morningside”). Key Upcoming Milestones
Financial Results for the three months ended June 30, 2021 Cash Position: Cash and cash equivalents were $30.8 million at June 30, 2021, compared to $32.8 million at December 31, 2020. In May 2021, the Company received $8.0 million under the Development Funding Agreement with Morningside and will receive an additional $22.0 million during the fourth quarter of 2021. The Company is also eligible to receive an additional $5.0 million upon submission of its Barth NDA, which is currently anticipated to be in August 2021. The Company expects that its cash, cash equivalents and investments as of June 30, 2021, together with the $27.0 million in expected proceeds to be received under the Development Funding Agreement, will be sufficient to enable it to fund its planned operations into the second quarter of 2022. Research and Development (R&D) Expenses: R&D expenses were $5.9 million for the three months ended June 30, 2021, compared to $7.4 million for the same period in 2020. The decrease was due to a net decrease of $2.2 million in clinical costs primarily driven by the closeout of our Primary Mitochondrial Myopathy development efforts offset in part by a $0.5 million increase in preclinical costs, an increase of $0.1 million in employee related costs and an increase of $0.1 million in manufacturing costs. General and Administrative (G&A) Expenses: G&A expenses were $5.1 million for the three months ended June 30, 2021, compared to $4.5 million for the same period in 2020. The increase was due to a $0.4 million increase in professional services, $0.3 million increase in precommercial costs and $0.1 million increase in costs of insurance, offset by $0.2 million decrease in facility related costs. Other Income (Expense): Other expense was $7.4 million for the three months ended June 30, 2021, compared to other expense of $0.4 million for the same period in 2020. Other expense in 2021 consisted of a $7.2 million loss due to the change in fair value of the derivative liability and $0.2 million in interest expense. Other expense in 2020 consisted of $0.4 million in interest expense. Net Loss: Net loss was $18.4 million, or $0.03 basic and diluted net loss per ordinary share, for the three months ended June 30, 2021, as compared to $12.4 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, Duchenne muscular dystrophy 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.
