Audentes Therapeutics Reports Fourth Quarter 2018 and Full Year Financial Results and Provides Corporate Update

SAN FRANCISCO, Feb. 27, 2019 /PRNewswire/ -- Audentes Therapeutics, Inc. (Nasdaq: BOLD), a biotechnology company focused on developing and commercializing innovative gene therapy products for patients living with serious, life-threatening rare diseases, today reported its financial results for the fourth quarter and full year ended December 31, 2018 and provided an update on the company's recent achievements and anticipated upcoming milestones.

"2018 was a transformative year marked by significant progress in advancing our mission to bring innovative gene therapy products to patients living with severe, life-threatening rare diseases," stated Matthew R. Patterson, Chairman and Chief Executive Officer.  "Importantly, we established a compelling clinical profile for AT132, our product candidate being developed to treat XLMTM, and are in ongoing discussions with the FDA and EMA to facilitate agreement on license application pathways for AT132." 

Mr. Patterson continued, "We enter 2019 with over two years of cash runway, a position of strength that will ensure our research and development efforts continue to advance across our promising portfolio.  To that end, we remain highly encouraged by preclinical work in our Pompe disease program and continue to guide to a third quarter IND submission for AT845.  We are also continuing to advance our new product candidate, AT720, a novel AAV-based therapeutic being developed to treat a large neuromuscular disease with significant unmet medical need, and plan to disclose the therapeutic target and provide a program overview in the second quarter of 2019."

Recent Achievements & Upcoming Key Events

AT132 for X-Linked Myotubular Myopathy (XLMTM):

• Completed productive initial interactions with the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) to discuss potential BLA and MAA submission pathways for AT132 under the Regenerative Medicine Advanced Therapy (RMAT) and Priority Medicines (PRIME) designations, respectively.
• Proceeding with previously announced plan to enroll an additional 3-5 patients in Cohort 2 (3x10¹⁴ vector genomes per kilogram) of ASPIRO, the Phase 1/2 study of AT132.
• On track to select optimal dose of AT132 in the second quarter of 2019. Optimal dose selection will be determined after an evaluation of the six-month biopsy results from the first three patients dosed in Cohort 2 of ASPIRO.
• Subsequent to the determination of the optimal dose, Audentes plans to provide an updated data package to FDA and EMA to facilitate final agreement on license application pathways in the third quarter of 2019.
• Continuing process and facility validation efforts based on preliminary FDA feedback on our chemistry, manufacturing, and controls (CMC) plans, to support AT132 registration efforts.
• Since program inception, AT132 clinical material has been manufactured utilizing the same process, facility, and scale intended to supply the commercial market.
• Next clinical data presentation planned at the 2019 Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) in Washington, D.C. from April 29th to May 2nd.

AT845 for Pompe Disease:

• Encouraged by continued progress in preclinical studies.
• On track to file IND in the third quarter of 2019.

AT342 for Crigler-Najjar Syndrome:

• VALENS Phase 1/2 study ongoing.
• Next program update planned in the second quarter of 2019.

Pipeline Expansion:

• Advancing our new product candidate, AT720, a novel AAV-based therapeutic being developed to treat a large neuromuscular disease with significant unmet medical need.
• On track to disclose the therapeutic target and provide a program overview in the second quarter of 2019.

Manufacturing:

• State-of-the-art, internal, large-scale cGMP manufacturing facility provides sufficient capacity for AT132 global commercialization as well as continued clinical development of pipeline programs.
• Currently operating in mammalian, serum-free suspension culture production process at 1,000-liter scale with the ability to add up to an additional 5,000 liters of capacity.
• Internal analytical development, fill-finish, and QC testing capabilities provide a fully-integrated platform to design, manufacture, fill, and release our product candidates for clinical and eventually, commercial use.

Corporate:

• Expanded our leadership team with the addition of Eric Mosbrooker, Senior Vice President and Chief Commercial Officer, to lead the development and execution of our global commercial strategy.

Fourth Quarter and Full Year 2018 Financial Results

• Cash Position: At December 31, 2018, Audentes had cash, cash equivalents, marketable securities and restricted cash of $418.1 million. In 2018, we strengthened the balance sheet with two follow-on financings, resulting in aggregate net proceeds of approximately $380 million after the deduction of underwriting discounts, commissions, and offering expenses. Our current cash, cash equivalents, and marketable securities are expected to fund operations into 2021.
• Research and Development Expenses: Research and development expenses were $28.2 million for the fourth quarter of 2018 and $104.4 million for the year ended December 31, 2018, compared to $21.7 million and $75.9 million, respectively, for the same periods in 2017. The increase in research and development expenses was primarily attributable to increases in our research and development headcount and related personnel and facilities costs as we continued to make investments in our internal research and development and manufacturing capabilities.
• General and Administrative Expenses: General and administrative expenses were $9.4 million for the fourth quarter of 2018 and $30.0 million for the year ended December 31, 2018, compared to $5.2 million and $17.3 million, respectively, for the same periods in 2017. The increase in general and administrative expenses was primarily attributable to increases in our general and administrative headcount and related personnel and facilities costs, increases in consulting, professional services and audit fees, and costs related to on-going regulatory compliance activities as a public company.
• Net Loss: Net loss was $35.6 million for the fourth quarter of 2018 and $128.8 million for the year ended December 31, 2018, compared to $24.4 million and $90.2 million, respectively, for the same periods in 2017.
