#### Exhibit 99.1

#### AVROBIO Reports Fourth Quarter and Fiscal Year 2022 Financial Results and

#### Provides Business Update

*Following positive regulatory feedback, plan to initiate registrational global Phase 2/3 clinical trial for Gaucher disease type 3 (GD3) in second half 2023, subject to regulatory alignment*

*Patient dosing completed in collaborator-sponsored Phase 1/2 clinical trial for cystinosis; plan to initiate late-stage clinical trial activities in second half 2023, subject to regulatory alignment; expect to provide clinical and regulatory update at the American Society of Gene & Cell Therapy (ASGCT) annual meeting in May 2023*

*Plan to initiate collaborator-sponsored Phase 1/2 clinical trial for mucopolysaccharidosis type II (MPS-II), or Hunter syndrome, in 2023*

CAMBRIDGE, Mass., March 23, 2023 -- AVROBIO, Inc. (Nasdaq: AVRO), a leading clinical-stage gene therapy company working to free people from a lifetime of genetic disease, today reported financial results for the fourth quarter and year ended Dec. 31, 2022 and provided a business update.

"2022 was a transformative year for AVROBIO, topped in December with a robust clinical and regulatory update for our Gaucher disease program. Gaucher disease is one of the most common lysosomal disorders, and the data presented highlighted the potential systemic impact of hematopoietic stem cell (HSC) gene therapy, including data suggesting certain improvements in some significant refractory elements of disease, for people living with Gaucher disease type 1 (GD1) and Gaucher disease type 3 (GD3)," said Geoff MacKay, president and CEO of AVROBIO. "Additionally, we're excited the collaborator-sponsored Phase 1/2 clinical trial for cystinosis has completed dosing and that data to date show the potential of the HSC gene therapy approach to stabilize or reduce the impact of cystinosis on different tissues throughout the body with a one-time dose. In 2023, we have already started and look forward to continuing to advance our Gaucher disease and cystinosis programs through anticipated near-term milestones."

#### Program Updates

#### <br>
<u>Presented new and encore clinical and preclinical data for AVROBIO's lysosomal disorder pipeline at the 19</u><sup><u>th</u></sup> <u>annual WORLD</u>*<u>Symposium</u>*<u>™, Feb. 22-26, 2023:</u>

 

<br> &nbsp;&nbsp;&nbsp;&nbsp;• "*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.

------

&nbsp;&nbsp;&nbsp;&nbsp;• "*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.

&nbsp;&nbsp;&nbsp;&nbsp;• "*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.

<br> o See ASGCT 2022 data press release here.

&nbsp;&nbsp;&nbsp;&nbsp;• "*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.

&nbsp;&nbsp;&nbsp;&nbsp;• "*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.

&nbsp;&nbsp;&nbsp;&nbsp;• "*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.

<u>Announced new positive clinical data and outlined clinical development plan for AVR-RD-02 in Gaucher disease on Dec. 7, 2022:</u>

 

<br> &nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

#### Fourth Quarter and Year End 2022 Financial Results

#### <br>
AVROBIO reported a net loss of $25.0 million for the fourth quarter of 2022, and a net loss of $105.9 million for the year ended 2022, as compared to a net loss of $28.2 million and a net loss of $119.1 million for the comparable periods in 2021, respectively.

Research and development expenses were $18.1 million for the fourth quarter of 2022, and $72.2 million for the year ended 2022, as compared to $19.0 million and $83.1 million for the comparable periods in 2021, respectively. This decrease was driven by a reduction in program development expenses and personnel-related costs, including non-cash stock-based compensation.

------

General and administrative expenses were $7.1 million for the fourth quarter of 2022, and $33.2 million for the year ended 2022, as compared to $9.0 million and $35.7 million for the comparable periods in 2021, respectively. This decrease was attributable to a decrease in personnel-related costs, including non-cash stock-based compensation, and a decrease in other expenses, primarily related to professional fees.

Other income (expense), net was $0.2 million for the fourth quarter of 2022 and ($0.5) million for the year ended 2022, as compared to ($0.3) million and ($0.3) million for the comparable periods in 2021, respectively. This increase in expense for the year is due to interest expense related to our term loan which was partially offset by an increase in interest income.

As of Dec. 31, 2022, AVROBIO had $92.6 million in cash and cash equivalents, as compared to $189.6 million in cash and cash equivalents as of Dec. 31, 2021. Based on AVROBIO's current operating plan, AVROBIO expects its cash and cash equivalents as of Dec. 31, 2022, will enable AVROBIO to fund its operating expenses and capital expenditure requirements into the first quarter of 2024.
