Audentes Therapeutics Reports on Recent Progress and Outlines 2019 Key Priorities
"2018 was an outstanding year for Audentes," stated
Mr. Patterson continued, "We are preparing for multiple milestones and inflection points across our portfolio of product candidates in the coming year, including the continuation of BLA and commercial readiness activities in our XLMTM program. To support this effort, we recently expanded our leadership team with the addition of Eric Mosbrooker, a seasoned executive with a demonstrated track-record of building global commercial organizations and successfully launching rare disease products, to lead the development and execution of our global commercial strategy. In our Pompe disease program, we are encouraged by the progress of our ongoing preclinical studies and are planning to file an IND for AT845 in the third quarter of 2019. We are also advancing 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. Finally, our ability to meet these important milestones is supported by a strong balance sheet. With over two years of cash runway, we are well-positioned to make meaningful progress toward our goal of providing transformative therapies to patients living with devastating rare diseases."
Mr. Patterson will provide a corporate update and 2019 outlook in a presentation at the 37th Annual
Key 2018 Accomplishments and 2019 Milestones
AT132 for XLMTM
- Reported promising safety, efficacy, and muscle biopsy data from ASPIRO. The latest ASPIRO data set (presented
October 2018) demonstrated all six treated patients in Cohort 1 (1x1014 vector genomes per kilogram (vg/kg) and the sentinel patient in Cohort 2 (3x1014 vg/kg) showed meaningful improvements in neuromuscular and respiratory function with results ranging from 4 to 48 weeks. Three patients achieved ventilator independence, and all other patients showed significant reductions in ventilator use. Additionally, week 24 muscle biopsy data for the first four treated patients showed robust tissue transduction, protein expression, and histological improvement.
- Completed dosing of full Cohort 2 (three treated patients and one delayed-treatment control), and plan to dose an additional three to five patients as part of a Cohort 2 expansion arm in early 2019. Next clinical data update planned at the 2019 Annual Meeting of the
American Society of Gene and Cell Therapy(ASGCT) in May.
- Awarded Regenerative Medicine Advanced Therapy (RMAT) and Priority Medicines (PRIME) designations by the
FDAand the EMA, respectively. Completed productive initial interactions with both agencies to discuss potential registration pathways for AT132. Plan to provide additional meeting details in Q1 2019.
AT845 for Pompe Disease
- Conducted encouraging preclinical studies of AT845 for the treatment of Pompe Disease, and plan to file IND in Q3 2019.
AT342 for Crigler-Najjar Syndrome
- Established initial proof of concept based on 12-week data from first patient enrolled in the VALENS Phase 1/2 study at a dose of 1.5x1012 vg/kg. Next program update planned in Q1 2019.
- Awarded Rare Pediatric Disease and Fast Track designations for AT342 by the
- Advancing our new product candidate, AT720, a novel AAV-based therapeutic being developed to treat a large neuromuscular disease with significant unmet medical need.
- Plan to disclose the therapeutic target and provide a program overview in Q2 2019.
- Commenced BLA readiness and process validation activities for AT132. Chemistry, manufacturing, and controls (CMC) approach is consistent with recent
FDAgene therapy guidance. Since program inception, clinical material has been manufactured utilizing substantially the same process, scale, and facility intended to supply the commercial market.
- Strengthened balance sheet with two follow-on financings, resulting in aggregate net proceeds of approximately
$380 millionafter the deduction of underwriting discounts, commissions, and estimated offering expenses.
- On a proforma basis at
September 30, 2018, Audentes had cash, cash equivalents and short-term investments totaling nearly $450 million, which includes net proceeds of $162.5 millionfrom its follow-on financing that closed in October 2018. These resources are expected to fund the company into 2021.
