"I am pleased with the excellent progress we have made to advance our pipeline toward key value inflection milestones, including the recent completion of dosing for the first cohort in ASPIRO, the Phase 1 / 2 clinical study of AT132 for the treatment of XLMTM," stated Matthew R. Patterson, President and Chief Executive Officer. "While we are only weeks into the study, we are encouraged by the progress to date and look forward to sharing preliminary safety and efficacy data from the first cohort of patients in early January 2018. This will be the first of many catalysts over the coming months as we execute on our ambitious goal of creating the world’s leading gene therapy company focused on developing a multi-product pipeline to treat serious, life-threatening rare diseases with high unmet medical need."

Recent Achievements & Upcoming Key Events

AT132 for X-Linked Myotubular Myopathy:
Completed dosing of the first cohort of patients in ASPIRO, the Phase 1 / 2 clinical study of AT132. To date, AT132 has been well-tolerated by all patients with no significant treatment-related safety signals.
Announced interim results from INCEPTUS, a prospective natural history run-in study in patients with XLMTM. The primary objectives of INCEPTUS are to characterize the clinical condition of children with XLMTM, identify subjects for potential enrollment in ASPIRO, and serve as a longitudinal baseline and with-in patient control for ASPIRO. Preliminary results from INCEPTUS confirm the significant neuromuscular and respiratory deficits experienced by XLMTM patients, and provide insight into the relevance and sensitivity of assessments used in the ASPIRO study.
Received approval for the Clinical Trial Authorisation (CTA) application for AT132 from the United Kingdom’s (U.K.) Medicines and Healthcare Products Regulatory Agency (MHRA), and anticipate initiation of U.K. enrollment in the first quarter of 2018 for ASPIRO.
Plan to report preliminary clinical data from ASPIRO in early January 2018
AT342 for Crigler-Najjar:
Plan to discuss initial results of LUSTRO, the prospective natural history run-in study being conducted in patients with Crigler-Najjar Syndrome, on the third quarter 2017 earnings call
Plan to dose first patient in VALENS, the Phase 1 / 2 clinical study of AT342, in the first quarter of 2018, and to report preliminary data in the second quarter of 2018
Received approval for the CTA application for AT342 from the MHRA, and anticipate initiation of U.K. enrollment in the first quarter of 2018 for VALENS
AT982 for Pompe Disease:
Conducting a comprehensive in vivo construct selection and dose-ranging study evaluating a range of AAV8 and AAV9 vector constructs designed to express GAA selectively within tissues relevant to Pompe disease, including skeletal muscle, motor neurons and liver. Candidate vectors are being evaluated across a broad range of neuromuscular function and biochemical endpoints at multiple dose levels.
Plan to select optimal construct and file IND in the first half of 2018
AT307 for CASQ2-CPVT:
Completed successful pre-IND/CTA meetings with both the U.S. Food and Drug Administration (FDA) and MHRA, and have incorporated input from both agencies into IND filing plans
Expect to file IND in the first quarter of 2018
Appointed Fulvio Mavilio, Ph.D. as Vice President Scientific Affairs, Europe. Dr. Mavilio is an internationally recognized scientific leader who has made important contributions to the field of molecular genetics and gene therapy for rare diseases.
Third Quarter 2017 Financial Results

Cash Position: As of September 30, 2017, Audentes had cash, cash equivalents and short-term investments of approximately $156.0 million.
R&D Expenses: Research and development expenses were $20.9 million for the third quarter of 2017 compared to $12.5 million for the same period in 2016, an increase of $8.4 million. The increase was primarily due to increased research and development expenses for our AT132 and AT307 programs, increases in our research and development headcount and higher facility costs as we made additional investments in our manufacturing and research facilities. For the nine months ended September 30, 2017, research and development expenses were $54.2 million compared to $32.2 million for the same period in 2016.
General and Administrative: General and administrative expenses were $4.3 million for the third quarter of 2017 compared to $2.9 million for the same period in 2016, an increase of $1.4 million. The increase was primarily due to increased G&A headcount and increases in other G&A expenses related to regulatory compliance and operations as a public company. For the nine months ended September 30, 2017, general and administrative expenses were $12.1 million compared to $8.0 million for the same period in 2016.
Net Loss: Net loss was $25.0 million for the third quarter of 2017, compared to a net loss of $15.4 million for the same period in 2016. For the nine months ended September 30, 2017, our net loss was $65.9 million as compared to $40.0 million for the same period in 2016.
