- On Track for Updates on pheEDIT and juMPStart Programs by Year-End -

- Strong Financial Position with Cash Runway into Fourth Quarter 2024 -

- Promoted Albert Seymour, Ph.D., to Chief Executive Officer Driving Clinical Trials and Genetic Medicines Platform Forward for Patients -

BEDFORD, Mass., Nov. 10, 2022 (GLOBE NEWSWIRE) -- Homology Medicines, Inc. (Nasdaq: FIXX), a genetic medicines company, announced today financial results for the third quarter ended September 30, 2022, and highlighted recent accomplishments.

“We remain on track to provide an update from our pheEDIT and juMPStart clinical trials, including site initiations and enrollment status, by the end of this year,” said Albert Seymour, Ph.D., President and Chief Executive Officer of Homology Medicines. “With our recent pipeline prioritization, which included devoting resources to our ongoing clinical trials and select preclinical programs, Homology extended its cash runway into the fourth quarter of 2024 through key milestones across all programs. We continue to progress HMI-104, our lead GTx-mAb development candidate, through IND-enabling studies and believe that our optimized in vivo gene therapy development candidate for MLD, which has demonstrated the ability to cross the blood-brain-barrier following a single I.V. administration in preclinical studies, is differentiated from other approaches and makes it an attractive program for us to partner. Our work to bring first-in-class genetic medicine candidates forward for patients is ongoing, and we look forward to sharing our continued progress.”

Third Quarter 2022 and Recent Highlights

• Announced a pipeline prioritization, which included shifting resources from the pheNIX gene therapy trial evaluating HMI-102 for phenylketonuria (PKU) and pausing enrollment to focus on generating data from the pheEDIT clinical trial that is evaluating in vivo gene editing candidate HMI-103 for PKU. The mechanism of action of this gene editing candidate has the potential to treat adults and ultimately pediatric patients.
• Continued to advance the juMPStart clinical trial evaluating in vivo gene therapy candidate HMI-203 for MPS II, or Hunter syndrome. Homology remains on track to provide an update on enrollment and site status for this trial and the pheEDIT trial by the end of this year.
• Continued to advance IND-enabling studies of HMI-104, a C5 antibody development candidate for paroxysmal nocturnal hemoglobinuria (PNH), which utilizes the Company’s GTx-mAb platform that has the potential to address larger market indications.
• Announced intention to partner the optimized in vivo gene therapy candidate HMI-204 for metachromatic leukodystrophy (MLD), which demonstrated the ability to cross the blood-brain-barrier as well as reach the central nervous system and key peripheral organs involved in MLD following a single I.V. administration.
• Presented design of the pheEDIT gene editing trial for HMI-103 and supporting preclinical data, as well as data that demonstrated the use of next-generation sequencing methods that can lead to improved AAVHSC vector design, which were featured at the American Society of Human Genetics Meeting.
• Promoted Albert Seymour, Ph.D., to Chief Executive Officer of Homology and to the Board of Directors, succeeding Arthur Tzianabos, Ph.D., who served as CEO and Board member since 2016 and who was appointed Chair of the Board in conjunction with this transition.
• Announced peer-reviewed publication in Scientific Reports, a Nature journal, on the use of long-read sequencing methods that could be applied to further characterize Homology’s AAVHSCs and optimize vector design.
• Spoke alongside industry leaders on panels focused on innovations in gene editing and AAV manufacturing during the Cell & Gene Meeting on the Mesa.

Third Quarter 2022 Financial Results

• As of September 30, 2022, Homology had approximately $201.1 million in cash, cash equivalents and short-term investments. Based on current projections, Homology expects cash resources to fund operations into the fourth quarter of 2024.
• Net loss for the quarter ended September 30, 2022 was $(33.7) million or $(0.59) per share, compared to a net loss of $(30.6) million or $(0.54) per share for the quarter ended September 30, 2021.
• Collaboration revenues for the quarter ended September 30, 2022 were $0.8 million, compared to $1.7 million for the quarter ended September 30, 2021. Collaboration revenue in each period included deferred revenue recognized under Homology’s stock purchase agreement with Pfizer. Collaboration revenues for the third quarter 2021 also included the recognition of deferred revenue and reimbursement of R&D expenses under the Company’s former collaboration with Novartis.
• Total operating expenses for the quarter ended September 30, 2022 were $33.7 million, compared to $32.3 million for the quarter ended September 30, 2021, and consisted of research and development expenses and general and administrative expenses.
• Research and development expenses for the quarter ended September 30, 2022 were $25.9 million, compared to $24.0 million for the quarter ended September 30, 2021. Research and development expenses increased primarily due to increased development costs for our ongoing HMI-103 and HMI-203 clinical-stage programs and earlier-stage programs. Partially offsetting these increases were lower employee-related costs as a result of transferring employees to Oxford Biomedica Solutions, the AAV Innovation and Manufacturing Business that Homology established with Oxford Biomedica in the first quarter of 2022 in order to leverage its in-house manufacturing capabilities while establishing a 20% stake and preferred customer status in the new business.
• General and administrative expenses for the quarter ended September 30, 2022 were $7.8 million, compared to $8.4 million for the quarter ended September 30, 2021. General and administrative expenses decreased primarily as a result of finance, human resources, IT and legal services provided by the Company to OXB Solutions under the transitional services agreement that provided for these services to be reimbursed, as well as decreased depreciation expense as the Company’s leasehold improvements were transferred to Oxford Biomedica Solutions. Partially offsetting these decreases was an increase in audit and legal fees.
