Third Quarter 2022 Financial Results

AVROBIO reported a net loss of $23.0 million for the third quarter of 2022 as compared to a net loss of $32.6 million for the comparable period in 2021. This decrease was driven by a reduction in research and development expenses.

Research and development expenses were $15.9 million for the third quarter of 2022 as compared to $23.0 million for the comparable period in 2021. 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 third quarter of 2022 as compared to $9.6 million for the comparable period in 2021. 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 facilities costs and professional fees.

Other income (expense), net was less than $0.1 million in income for the third quarter of 2022 as well as for the comparable period in 2021.

As of September 30, 2022, AVROBIO had $116.0 million in cash and cash equivalents, as compared to $189.6 million in cash and cash equivalents as of December 31, 2021. Based on AVROBIO’s current operating plan, AVROBIO expects its cash and cash equivalents as of September 30, 2022, will enable AVROBIO to fund its operating expenses and capital expenditure requirements into the first quarter of 2024.

About AVROBIO

Our vision is to bring personalized gene therapy to the world. We target the root cause of genetic disease by introducing a functional copy of the affected gene into patients’ own hematopoietic stem cells (HSCs), with the goal to durably express the therapeutic protein throughout the body, including the central nervous system. Our first-in-class pipeline includes clinical programs for cystinosis and Gaucher disease type 1, as well as preclinical programs for Gaucher disease type 3, Hunter syndrome and Pompe disease. Our proprietary plato® gene therapy platform is designed to be scaled to support late-stage clinical development and commercialization globally. We are headquartered in Cambridge, Mass.
