U.S. Food and Drug Administration granted Fast Track Designation to AVR-RD-04 for cystinosis
Company is planning to initiate multiple registration trials in 2022
Multiple data and regulatory updates anticipated over next 12 months
CAMBRIDGE, Mass., August 05, 2021--(BUSINESS WIRE)--AVROBIO, Inc. (Nasdaq: AVRO), a leading clinical-stage gene therapy company with a mission to free people from a lifetime of genetic disease, today reported financial results for the quarter ended June 30, 2021, and provided a business update.
"Data from the patients dosed to date across three indications continue to support our first-in-class, one-time investigational gene therapies as potentially transformative treatments for the more than 50,000 people worldwide living with the life-limiting lysosomal disorders we are researching," said Geoff MacKay, president and CEO of AVROBIO. "In the second half of this year, we plan to share updated safety data from our ongoing clinical trials and plan to meet with regulatory agencies to discuss initiating potential registration trials in 2022 for Fabry disease, cystinosis and Gaucher disease type 3. With our Pompe disease and Hunter syndrome programs anticipated to enter the clinic in 2022, we remain fiercely committed to our purpose: to free people living with genetic disease from a lifetime of symptoms, chronic treatment and inevitable disease progression."
Multiple program milestones anticipated over the next 12 months
AVR-RD-01 in Fabry disease:
Two additional patients have been dosed in the FAB-GT trial since June 2021.
AVROBIO intends to amend the FAB-GT Phase 2 trial protocol in August 2021 to include female participants and eliminate the antibody status exclusion as well as collect additional central nervous system (CNS) and cardiovascular data.
Company plans to engage the U.S. Food and Drug Administration (FDA) to discuss a revised regulatory approach with the goal of initiating a registration trial in mid-2022.
AVROBIO expects to present updated safety and tolerability data on all nine FAB-GT Phase 2 patients dosed to date in the fourth quarter of 2021 and updated efficacy and durability data for all dosed patients at the 18th Annual WORLDSymposium in February 2022.
AVR-RD-04 in cystinosis:
FDA granted Fast Track Designation for AVR-RD-04 and cleared the Investigational New Drug (IND) application for the AVROBIO long-term follow up trial for patients dosed in the investigator-sponsored Phase 1/2 clinical trial1 of AVR-RD-04 (CTNS-RD-04) led by our collaboration partner at University of California San Diego (UCSD).
Stephanie Cherqui, Ph.D., principal investigator of the investigator-sponsored Phase 1/2 clinical study, provided an update on the patients dosed to date in the Phase 1/2 trial at the virtual 24th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT), May 11-14, 2021.
AVROBIO expects to provide a clinical and regulatory update in the first quarter of 2022 and is planning to initiate a company-sponsored clinical trial in the second half of 2022, which it believes could potentially serve as a registration trial, subject to regulatory clearance.
Gaucher disease programs:
AVR-RD-02 in Gaucher disease type 1:
The first patient dosed has completed the 48-week Phase 1/2 Guard1 trial and has enrolled in the long-term follow up trial, where patients will be followed for 14 years after the initial trial period. AVROBIO is currently enrolling additional patients in the Phase 1/2 trial.
AVROBIO expects to present updated safety data on Patient 1 in the fourth quarter of 2021 and a full program update in the first half of 2022.
AVR-RD-06 in Gaucher disease type 3:
AVROBIO plans to engage regulatory agencies to discuss the regulatory strategy for AVR-RD-06, the company’s program for Gaucher disease type 3, a form of Gaucher disease associated with severe neurological symptoms.
The company is planning to initiate a potential registration trial of AVR-RD-06 in patients with Gaucher disease type 3 in the second half of 2022, subject to regulatory clearance.
Second Quarter 2021 Financial Results
AVROBIO reported a net loss of $31.4 million for the second quarter of 2021 as compared to a net loss of $28.8 million for the comparable period in 2020. This increase was driven by increased research and development expenses as well as increased general and administrative expenses.
Research and development expenses were $22.5 million for the second quarter of 2021 as compared to $20.9 million for the comparable period in 2020. This increase was driven by increased program development activities related to the advancement of the company’s pipeline as well as increased personnel-related costs resulting from an increase in employee headcount, which includes the impact of non-cash stock-based compensation.
General and administrative expenses were $8.9 million for the second quarter of 2021 as compared to $8.0 million for the comparable period in 2020. This increase was primarily due to an increase in employee headcount, which includes the impact of non-cash stock-based compensation, which was offset by a decrease in facilities costs, professional fees and legal fees.
As of June 30, 2021, AVROBIO had $226.4 million in cash and cash equivalents, as compared to $259.7 million in cash and cash equivalents as of Dec. 31, 2020. Based on the company’s current operating plan, AVROBIO expects its cash and cash equivalents as of June 30, 2021 will enable the company to fund its operating expenses and capital expenditure requirements into the first quarter of 2023.
