“Sustained improvement of clinical CNS and somatic features of GD3 after HSC gene therapy: A first-in-world
report” -- Clinical data from the first pediatric GD3 patient, dosed with investigational AVR-RD-02, was presented by one of the patient’s physicians from the University
of Manchester (UoM), U.K. GD3 is a more severe, progressive form of Gaucher disease than GD1, the first indication that was dosed with AVR-RD-02. These data
were initially presented during AVROBIO’s Dec. 7, 2022, Gaucher disease program update, and included some new data, including longer time points for peripheral blood glucocerebrosidase, chitotriosidase and albumin levels, all trending
consistently with previously presented data. The 11-year-old GD3 patient was dosed at UoM on a named patient basis.
|
• |
“The Guard1 clinical trial – A first in-human, Phase 1/2 study evaluating AVR-RD-02, an HSC gene therapy for
Gaucher disease: Preliminary safety, pharmacodynamic and clinical efficacy results from the subjects observed for up to 24 months post-infusion” -- AVROBIO presented safety and efficacy data of AVR-RD-02, AVROBIO’s investigational
gene therapy for GD1, which were previously shared by the company on Dec. 7, 2022.
|
• |
“Phase 1/2 clinical trial of autologous hematopoietic stem and progenitor cell (HSPC) gene therapy for cystinosis”
-- Collaborators at the University of California, San Diego, presented some updated data on the six patients dosed in the fully enrolled Phase 1/2 clinical trial since the last data update at ASGCT 2022, including additional vector copy
number (VCN) data, as well as longer time points for leukocyte cystine levels and skin and GI mucosa cystine crystal data, for some patients. As of the most recent safety data cut-off date of Jan. 9, 2023, all clinical and safety data updates
are trending consistently with the prior reported data.

• |
“Validation of a GMP stem cell gene therapy manufacturing process for mucopolysaccharidosis type II (MPS II) in
preparation for an approved Phase 1/2 clinical trial” -- Collaborators at UoM highlighted data validating their manufacturing process in preparation for a Phase 1/2 clinical trial for Hunter syndrome anticipated to start later this
year.
|
• |
“Validation of an assay to measure iduronate-2-sulfatase activity in cerebrospinal fluid to assess the efficacy
of an HSC gene therapy” -- Collaborators at UoM shared a poster with new data validating their assay to measure changes in Iduronate-2-sulphatase (IDS) enzyme activity in the cerebrospinal fluid (CSF) in MPS-II, or Hunter syndrome, to be used in the Phase 1/2 clinical trial evaluating HSC gene therapy. Data also demonstrated repeatability and reproducibility of the assay.
|
• |
“Using IVIM/SAGA as screening tools during lentiviral vector lead selection for detection of clinically
translatable insertional transformational risk” -- AVROBIO shared a poster reporting favorable data on the combined use of two state-of-the-art assays to evaluate the genotoxicity risk of integrating vectors used in HSC gene therapy
prior to clinical use.
|
• |
Presented compelling data from first-ever pediatric GD3 patient showing biochemical correction with lymphadenopathy and enteropathy improvements and neurological stabilization, indicating
improvement in major refractory elements of disease 15 months post gene therapy.
|
• |
In the Guard1 clinical trial for GD1, data from first adult patients out more than 26 weeks post gene therapy included clinically significant reductions below baseline enzyme replacement
therapy (ERT) levels in liver and spleen volume.
|
• |
Safety data to date from GD1 and GD3 patients indicate no adverse events (AEs) related to drug product. All AEs observed were related to myeloablative conditioning, stem cell mobilization,
underlying disease or pre-existing conditions.
|
• |
Following positive feedback from the U.S. Food and Drug Administration (FDA) and U.K. Medicines and Healthcare products Regulatory Agency (MHRA), a registrational, global Phase 2/3 clinical
trial for GD3, now referred to as Guard3, is planned for the second half 2023, subject to regulatory alignment.
|
• |
No major chemistry, manufacturing and controls (CMC) changes are anticipated for AVROBIO’s plato® gene therapy platform as the company prepares to enter a registrational trial for GD3.
