AVROBIO Highlights the plato™ Platform and Gaucher and Cystinosis Programs at the 2019 Annual Meeting of the American Society of Gene and Cell Therapy

CAMBRIDGE, Mass.--(BUSINESS WIRE)--

AVROBIO, Inc. (AVRO) (the “Company”), a Phase 2 clinical-stage gene therapy company, today announced the participation of its senior management in sessions at the Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT). These include sessions on advances in gene therapy research, manufacturing challenges during the development of gene therapy products, and the potential benefits of the Company’s plato™ platform. In addition, multiple oral presentations with preclinical data from the Company’s gene therapy programs in Gaucher disease and cystinosis are also on the program at the ASGCT Annual Meeting.

“After more than three and a half years of development, we continue to be on track towards our anticipated introduction of plato™ upgrades into our clinical programs in the second half of 2019,” said Geoff MacKay, AVROBIO’s President and CEO. “The plato platform includes a proprietary vector system, an automated cell manufacturing solution and refined conditioning regimen with therapeutic drug monitoring. We’re especially pleased that our Head of Operations, Kim Warren, PhD, is able to share our manufacturing and operations experience with the gene and cell therapy community at ASGCT. The plato platform is designed to overcome many of the identified constraints and challenges of developing, manufacturing and commercializing gene therapies.”

Dr. Warren is an invited expert panelist at the Pre-approval Commercialization Workshop on “Manufacturing Challenges During Late Phase Development of Gene Therapy Products.” During a session on the latest advances in cell therapy research, AVROBIO’s Senior Director of Manufacturing Operations, Azadeh Golipour, PhD, will present “Automated Gene Modified Cell Production: Concept to Process Verification” which describes the development of the automated cell process.

  • Title: Manufacturing Challenges during Late Phase Development of Gene Therapy Products
  • Presenter: Kim Warren, PhD, AVROBIO
  • Date/time: Sunday April 28; 3 PM - 4:30 PM
  • Location: Jefferson West
  • Title: Automated Gene Modified Cell Production: Concept to Process Verification
  • Presenter: Azadeh Golipour, PhD, AVROBIO
  • Date/time: Tuesday April 30; 1:00 PM - 1:25 PM
  • Location: Monroe

In several oral presentations at ASGCT, preclinical data will be presented by AVROBIO’s academic collaborators and their colleagues, related to the Company’s gene therapy programs in Gaucher disease and cystinosis.

Gaucher disease ASGCT oral presentation and gene therapy program

An oral presentation will be made at ASGCT with preclinical data results related to the gene therapy program for Gaucher disease led by Stefan Karlsson, MD, PhD, Professor at the Division of Molecular Medicine and Gene Therapy at Lund University in Sweden. AVROBIO has received clearance for its clinical trial application (CTA) from Health Canada. The Company plans to initiate its GAU-201 Phase 1/2 clinical trial of AVR-RD-02 in patients with Gaucher disease in the second half of 2019 utilizing the plato platform.

  • Title: A Clinical Glucocerebroidase Lentiviral Vector Corrects the Pathology and Clinical Signs in a Mouse Model for Type 1 Gaucher Disease
  • Presenter: Stefan Karlsson, MD, PhD, Lund University, Sweden
  • Date/time: Monday April 29; 10:45 AM - 11:00 AM
  • Location: Heights Courtyard 2

Cystinosis ASGCT oral presentations and gene therapy program

Three oral presentations will be made at ASGCT related to the cystinosis gene therapy program led by Stephanie Cherqui, PhD, Associate Professor at the Department of Pediatrics at University of California, San Diego (USCD). In January 2019, AVROBIO announced that the U.S. Food and Drug Administration (FDA) had cleared the investigational new drug (IND) application for the planned investigator-sponsored Phase 1/2 clinical trial for AVR-RD-04 gene therapy in cystinosis to be conducted by UCSD. Rights are licensed to AVROBIO to develop AVR-RD-04 as a potential one-time gene therapy for the treatment of cystinosis.

  • Title: Toxicology Studies for Hematopoietic Stem & Progenitor Cell Gene Therapy for Cystinosis Revealed an Unexpected Cytotoxicity of Polybrene to the Ctns-/- Sca1+Cells
  • Presenters include: Jay Sharma, University of California, San Diego
  • Session: Nonclinical Studies and Assay Development
  • Date/time: Tuesday April 30; 4:30 PM - 4:45 PM
  • Location: Heights Courtyard 2
  • Title: HSPC Gene Therapy for Cystinosis Remains Effective in Patients Carrying the Large Deletion abolishing SHPK expression
  • Presenter: Spencer Goodman, University of California, San Diego
  • Date/time: Wednesday May 1; 4:45 PM - 5:00 PM
  • Location: Holmead
  • Title: Hematopoietic Stem Cell Gene Therapy and Lysosomal Cross Correction for Cystinosis
  • Presenter: Stephanie Cherqui PhD, University of California, San Diego
  • Date/time: Thursday May 2; 8:00 AM - 8:30 AM
  • Location: International Ballroom East

“We believe that Dr. Karlsson’s Gaucher mouse model proof-of-concept work shows multiple positive preclinical findings, including prevention and reversal of disease manifestations, as well as improvement trends in multiple bone parameters. Bone data are important because according to The National Gaucher Foundation bone problems are common in people living with Gaucher disease,” said Birgitte Volck, MD, PhD, President of Research and Development at AVROBIO. “Stephanie Cherqui, PhD, and her team are also sharing valuable insights into ex vivo gene therapy for cystinosis. Both of these programs, for Gaucher and cystinosis, are expected to begin clinical studies in the second half of 2019.”
