Enrolled 4 patients in Cohort 2 of the upliFT-D trial for FTD-GRN, with patient dosing advancing as planned; 12-month Cohort 1 and interim Cohort 2 data expected in 1H25
Updated interim data from Cohort 1 FTD-GRN showed PBFT02 was generally well-tolerated and elevated CSF progranulin levels for up to 12 months following treatment
Highlighted robust preclinical data supporting PBFT02 as a potential best-in-class progranulin-raising therapy in an oral presentation at ESGCT
Execution backed by strong balance sheet, with cash runway to the end of Q2 2026
PHILADELPHIA, Nov. 13, 2024 (GLOBE NEWSWIRE) -- Passage Bio, Inc. (Nasdaq: PASG), a clinical stage genetic medicines company focused on improving the lives of patients with neurodegenerative diseases, today reported financial results for the third quarter ended September 30, 2024 and provided recent business highlights.
“This quarter, we’ve made important strides in advancing our PBFT02 gene therapy program,” said Will Chou, M.D., president and chief executive officer of Passage Bio. “Execution of our ongoing upliFT-D trial for FTD-GRN remains our core priority, and we are pleased to share that 4 patients in Cohort 2 have been enrolled, with patient dosing progressing as planned. We remain on track to share 12-month Cohort 1 and interim Cohort 2 data in the first half of 2025, which will strengthen our understanding of the therapeutic potential of PBFT02. Furthermore, our presentations of preclinical and positive interim safety and biomarker data at key scientific conferences underscore the potential of PBFT02 to be a market leading progranulin-raising therapy. Our commitment to disciplined execution and a strong balance sheet strategically position us to achieve several key milestones over the coming quarters.”
Recent Highlights
Sustained enrollment progress in global Phase 1/2 upliFT-D trial of PBFT02 for the treatment of patients with FTD-GRN: The company has enrolled 4 patients in Cohort 2, which will continue to evaluate Dose 1 of PBFT02, and patient dosing is underway and advancing as planned. With this momentum, the company remains on track to report 12-month data from Cohort 1 and interim data from Cohort 2 in 1H25.Presented encouraging interim data from Cohort 1 patients in upliFT-D trial of PBFT02 for FTD-GRN at the ISFTD2024 and CTAD conferences: The company presented updated safety and biomarker data from Cohort 1 patients in the upliFT-D trial during an oral presentation at the International Conference on Frontotemporal Dementias (ISFTD2024) conference in September and a poster session at the Clinical Trials on Alzheimer’s Disease conference (CTAD) in October. The data showed that PBFT02 produced consistent and durable increases in CSF PRGN expression in all treated Cohort 1 patients, with elevated levels maintained for up to one-year post-treatment. Furthermore, PBFT02 continued to exhibit a favorable safety profile in all patients who received the enhanced immunosuppression regimen, with no serious adverse events or clinically significant immune responses observed.Presented preclinical and interim clinical data for PBFT02 in FTD-GRN at the ESGCT conference: In October, the company delivered an oral presentation highlighting preclinical data for PBFT02 at the European Society of Gene & Cell Therapy (ESGCT) conference. The presentation reviewed the robust preclinical findings informing vector and dose selection and demonstrated the positive effects of elevating progranulin levels in vivo. Preclinical non-human primate (NHP) data found the AAV1 vector achieved superior human progranulin levels in the CSF compared to AAV5 and AAVhu68 (an AAV9 variant). Additionally, a dose escalation study in Grn knockout mice showed that PBFT02 improved lysosomal histopathology and reduced neuroinflammation in brain regions impacted by FTD pathology with evidence suggesting that the greatest pathological benefit was associated with the highest PGRN levels in the CSF. An NHP biodistribution study also showed that intra-cisterna magna (ICM) administration of PBFT02 resulted in widespread vector distribution in the brain and spinal cord.Appointed Tom Kassberg to the company’s board of directors: In September, the company announced the appointment of Tom Kassberg, Chief Business Officer and Executive Vice President at Ultragenyx, to its board of directors and his appointment to the Audit Committee. Mr. Kassberg brings extensive experience in corporate development and strategic planning to the company, having successfully led multiple business development and alliance management initiatives that advanced late-stage gene therapies for rare diseases.
