Audentes Therapeutics Reports Third Quarter 2018 Financial Results and Provides Corporate Update

SAN FRANCISCO, Nov. 6, 2018 /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 third quarter ended September 30, 2018 and provided an update on the company's recent achievements and upcoming milestones.

"In the third quarter, we continued to see exciting progress in the clinical development of AT132," stated Matthew R. Patterson, Chairman and Chief Executive Officer.  "We recently presented new ASPIRO data at the 23rd International Annual Congress of the World Muscle Society demonstrating significant and durable improvements in neuromuscular and respiratory function in all treated patients.  We are particularly pleased that three of our Cohort 1 patients have achieved ventilator independence, an unprecedented result for children with congenital myopathies that have been ventilated since birth.  In addition, we have recently completed enrollment of the Cohort 2 dose of 3x10¹⁴ vg/kg, including three treated patients and one untreated control patient.  We look forward to engaging with the FDA and EMA in the coming weeks to discuss development plans and the potential registration pathway for AT132, and to advance our goal of making this important treatment available to patients living with XLMTM as rapidly as possible."

Mr. Patterson continued, "Additionally, our recent follow-on financing positions Audentes to deliver on many important milestones, including the initiation of our commercial planning activities for AT132, progression of our Pompe program toward IND, and expansion of our pipeline of innovative AAV-based product candidates targeting neuromuscular diseases with significant unmet medical need."

Recent Achievements & Upcoming Key Events

• AT132 for XLMTM:
• Presented additional positive interim data from ASPIRO during an oral presentation at the 23rd International Annual Congress of the World Muscle Society (WMS)
• The ASPIRO WMS data set included safety and efficacy results ranging from 4 to 48 weeks for eight patients enrolled in ASPIRO, including the seven patients enrolled in Cohort 1 (1x10¹⁴ vg/kg; six treated and one untreated control) and the sentinel patient in Cohort 2 (3x10¹⁴ vg/kg), as well as week 24 muscle biopsy data for the first four treated patients.  All treated patients showed meaningful improvements in neuromuscular and respiratory function.  Three patients achieved ventilator independence, and all other patients showed significant reductions in ventilator dependence.  Additionally, the growing body of week 24 muscle biopsy data continued to show robust tissue transduction, protein expression, and histological improvement with AT132 treatment at the initial 1x10¹⁴ vg/kg dose.
• Completed enrollment of Cohort 2 of ASPIRO, including three patients treated at a dose of 3x10¹⁴ vg/kg and one enrolled as the Cohort 2 untreated control
• Awarded Regenerative Medicine Advanced Therapy (RMAT) designation by the FDA
• Plan to engage with FDA and EMA in Q4 2018 to discuss development plans and the potential registration pathway for AT132 in both the United States and Europe
• Next program update planned in Q1 2019
• AT982 for Pompe Disease:
• Completed analysis of nonclinical studies and determined mechanism of the dose-dependent safety signal observed in the NHP toxicology study
• Additional IND-enabling studies underway in the Pompe mouse model
• Plan to file IND in 2019
• AT342 for Crigler-Najjar Syndrome:
• Enrollment in VALENS Phase 1/2 study ongoing
• Next program update planned in Q1 2019
• Pipeline expansion:
• Continuing to advance our research initiative focused on the design and development of a novel AAV-based therapeutic targeting a large neuromuscular disease with significant unmet medical need
• Manufacturing:
• Continuing BLA preparation and validation efforts for our internal cGMP manufacturing facility, AT132 process and analytical methods
• Since program inception, clinical material has been manufactured utilizing substantially the same process, scale, and facility intended to supply the commercial market
• Current facility, scale and process yield provide sufficient capacity for the expected global commercial needs of XLMTM and Crigler-Najjar markets, and ongoing clinical supply for current and planned pipeline programs

Third Quarter 2018 Financial Results

• Cash Position: As of September 30, 2018, we had cash, cash equivalents, marketable securities and restricted cash of $285.5 million, which includes approximately $3.6 million of restricted cash and approximately $1.3 million of long-term investments.  In October 2018, we further strengthened our balance sheet with the completion of a follow-on financing, issuing 5,980,000 shares of common stock (inclusive of 780,000 shares of common stock pursuant to the underwriters' option to purchase additional shares) at an offering price of $29.00 per share, resulting in net proceeds of approximately $162.8 million after the deduction of underwriting discounts, commissions and estimated offering expenses.  Our current cash, cash equivalents, and marketable securities are expected to fund operations into 2021.
• Research and Development Expense: Research and development expense was $29.9 million for the third quarter of 2018 compared to $20.9 million for the same period in 2017, an increase of $9.0 million.  The increase in research and development expense was primarily attributable to an increase in development costs related to our AT982 program, increased headcount and related facility costs, increased internal manufacturing costs and higher stock-based compensation expense.  Research and development expense for the third quarter includes $2.6 million of non-cash stock-based compensation expense.  For the nine months ended September 30, 2018, research and development expense was $76.2 million compared to $54.2 million for the same period in 2017.
• General and Administrative Expense: General and administrative expense was $7.8 million for the third quarter of 2018 compared to $4.3 million for the same period in 2017, an increase of $3.5 million.  The increase in general and administrative expense was primarily attributable to increases in headcount and related facility costs, professional service fees, stock-based compensation expense and compliance costs associated with operating as a public company.  General and administrative expense for the third quarter includes $2.0 million of non-cash stock-based compensation expense.  For the nine months ended September 30, 2018, general and administrative expense was $20.6 million compared to $12.1 million for the same period in 2017.
• Net Loss: Net loss was $36.3 million for the third quarter of 2018 compared to $25.0 million for the same period in 2017.  For the nine months ended September 30, 2018, net loss was $93.2 million as compared to $65.9 million for the same period in 2017.
