SAN FRANCISCO, Jan. 9, 2017 /PRNewswire/ -- Audentes Therapeutics, Inc. (Nasdaq: BOLD), a biotechnology company focused on developing and commercializing gene therapy products for patients living with serious, life-threatening rare diseases, today provided its full-year 2017 strategic outlook and financial guidance.

"2016 was a year marked by the achievement of significant milestones for Audentes," stated Matthew R. Patterson, President and Chief Executive Officer. "We completed preclinical development for three programs, filed an IND for our Crigler-Najjar program, commenced key clinical activities for our XLMTM program, established large scale cGMP manufacturing at our internal manufacturing facility, and completed a successful IPO. We believe these accomplishments provide a strong foundation for a promising 2017."

Mr. Patterson continued, "As we look forward to the year ahead, we are excited by the prospect of initiating clinical trials in multiple programs. We expect to obtain preliminary data from our lead programs by year end, highlighted by the ASPIRO phase 1/2 study for the treatment of XLMTM and the VALENS phase 1/2 study for Crigler-Najjar. Additionally, we plan to establish internal cGMP manufacturing for our Pompe disease and CPVT programs. By hitting these milestones, we will make meaningful progress toward achieving our goal of providing transformative gene therapy products for the patients we serve."

Mr. Patterson will provide a corporate update and 2017 outlook in a presentation at the 35(th) Annual JP Morgan Healthcare Conference on January 10, 2017 at 5:00 pm PST. To access the live webcast of the presentation, please visit the Events & Presentations page within the Investors & News section of the Audentes website. Replays of the live webcast will be available on the Audentes website for approximately 30 days following the conference.

Key 2016 Accomplishments


    --  Filed IND with FDA for AT342 in Crigler-Najjar Syndrome:  Represents the
        first IND filed by Audentes for an AAV gene therapy product.
    --  Initiated large-scale cGMP production at state-of-the-art internal gene
        therapy manufacturing facility: The company intends to initiate clinical
        trials for two of its products, AT132 for X-Linked Myotubular Myopathy
        (XLMTM) and AT342 for Crigler-Najjar Syndrome, in 2017 with material
        manufactured in this facility.  The plant has been designed and
        commissioned as a multi-product facility intended to support commercial
        licensure by both the U.S. Food and Drug Administration and European
        Medicines Agency.
    --  Commenced enrollment in INCEPTUS: INCEPTUS is a prospective clinical
        assessment and phase 1/2 run-in study designed to characterize disease
        presentation in boys aged three years or younger living with XLMTM.
        INCEPTUS is designed to serve as a longitudinal baseline and
        within-patient control for subjects who enroll in the ASPIRO phase 1/2
        study.  As of January 1, 2017, 12 of the expected 12 to 15 patients have
        been enrolled.
    --  Completed initial public offering: Strengthened the balance sheet with
        the completion of an initial public offering in July 2016 resulting in
        aggregate cash proceeds to the company of $75.2 million, net of
        underwriting discounts, commissions and offering costs.

2017 Outlook for Development Pipeline

AT132 for X-Linked Mytubular Myopothy
AT132 is an AAV8 vector containing a functional copy of the MTM1 gene for the treatment of XLMTM, a rare monogenic disease characterized by extreme muscle weakness, respiratory failure and early death, with an estimated 50% mortality rate by 18 months of age. Multiple studies in animal models of XLMTM have demonstrated that a single administration of AT132 significantly improves disease symptoms and survival rates. In one study, these effects have lasted approximately four years to date.

Planned 2017 Milestones 


    --  File IND in the first quarter of 2017
    --  Complete enrollment and continue data collection in INCEPTUS, a clinical
        assessment and phase 1/2 run-in study
    --  Commence enrollment in ASPIRO, a phase 1/2 multicenter, multinational,
        open-label, ascending dose, delayed-treatment concurrent control
        clinical study in 12 patients
    --  Continue internal cGMP manufacturing to supply ASPIRO
    --  Report preliminary clinical data by the end of 2017

AT342 for Crigler-Najjar Syndrome
AT342 is an AAV8 vector containing a functional copy of the UGT1A1 gene for the treatment of Crigler-Najjar, a rare monogenic disease characterized by severely high levels of unconjugated bilirubin in the blood and risk of irreversible neurological damage and death. The current standard of care for Crigler-Najjar is persistent phototherapy, usually for longer than 12 hours per day. Phototherapy wanes in effectiveness beginning around age four, and a liver transplant may be required for survival. A single administration of AT342 has generated durable, dose-responsive and clinically-relevant decreases in total bilirubin levels in a mouse model of Crigler-Najjar.

Planned 2017 Milestones


    --  Commence enrollment in LUSTRO, a clinical assessment and phase 1/2
        run-in study intended to characterize the disease course, natural
        history, bilirubin variability and phototherapy usage in subjects with
        Crigler-Najjar
    --  Commence enrollment in VALENS, a phase 1/2 multicenter, multinational,
        open-label ascending dose, delayed-treatment concurrent control clinical
        study in 12 patients
    --  Conduct internal cGMP manufacturing to supply VALENS
    --  Report preliminary clinical data by the end of 2017

AT982 for Pompe Disease
 AT982 is an AAV9 vector containing a functional copy of the GAA gene designed to treat Pompe disease. Pompe disease is a rare monogenic disease characterized by severe muscle weakness, respiratory failure leading to ventilator dependence and, in infants, increased cardiac mass and heart failure. Treatment with AT982 in a mouse model of Pompe disease resulted in significant improvements in weight gain, ventilation parameters, glycogen deposition and cardiac left ventricle mass. The only approved treatment for Pompe disease is enzyme replacement therapy (ERT). Although ERT is the current standard of care for the disease, it has a number of recognized limitations.

Planned 2017 Milestones


    --  Establish internal cGMP manufacturing
    --  Conduct additional preclinical studies in support of an IND for a phase
        1/2 clinical study evaluating systemic administration of AT982 in
        patients with Pompe disease
    --  Conduct preclinical proof-of-concept studies evaluating intrathecal
        administration of AT982
    --  Report preliminary data from an investigator-sponsored study evaluating
        intramuscular injection of AT982 in the tibialis anterior muscle of
        adults with Pompe disease by the end of 2017

AT307 for CASQ2-Catecholaminergic Polymorphic Ventricular Tachycardia ( CASQ2-CPVT)
 AT307 is an AAV9 vector containing a functional copy of the CASQ2 gene for the treatment of CASQ2-CPVT, a rare monogenic disease that is characterized by life-threatening arrhythmias that may lead to sudden cardiac death. Treatment with AT307 in mouse models of CASQ2-CPVT has generated highly significant reductions in ventricular arrhythmic events following a single administration.

Planned 2017 Milestones


    --  Complete IND enabling preclinical studies
    --  Establish internal cGMP manufacturing
    --  File IND by the end of 2017
