• Continued momentum in upliFT-D trial of PBFT02 for the treatment of patients with frontotemporal dementia (FTD) with granulin mutations (GRN) with clinical trial site expansion into Europe and seven global sites now activated
• Pursuing new indications for PBFT02, including adult neurodegenerative diseases FTD-C9orf72, amyotrophic lateral sclerosis (ALS) and Alzheimer's disease
• Ended 2023 with robust balance sheet sufficient to deliver meaningful clinical data; with cash runway into Q4 2025
  

PHILADELPHIA, March 04, 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 fourth quarter and year ended December 31, 2023 and provided recent business highlights.

"In 2023, we achieved a significant milestone by announcing encouraging data from three patients in Cohort 1 of our FTD-GRN program. This data showcased the ability of PBFT02 to raise CSF progranulin to supraphysiologic levels, even at the lowest dose, Dose 1, and positions PBFT02 as a potential best-in-class treatment for FTD-GRN. Our global upliFT-D study continues to see strong momentum, and we're excited to announce the activation of our first clinical trial site in Europe to further bolster recruitment efforts. We are on track to complete dosing for Cohort 1 patients in the first half of this year and share 6-month additional safety and biomarker data from Cohort 1 in the second half of 2024," said Will Chou, M.D., president and chief executive officer of Passage Bio. "Buoyed by this promising data and additional evidence supporting progranulin's role in neurodegeneration, we are optimistic about expanding the application of PBFT02 beyond FTD-GRN and into new indications with significant unmet needs, including FTD-C9orf72, ALS, and Alzheimer's disease. We eagerly anticipate a catalyst-rich 2024, supported by our robust balance sheet, bringing us closer to improving patient outcomes across neurodegenerative diseases."

Recent Highlights

• Sustained momentum in global Phase 1/2 upliFT-D clinical trial evaluating PBFT02 for frontotemporal dementia (FTD) with granulin mutations (GRN), marked by the activation of two new trial sites and expansion into Europe: Initial data from the first three patients in Cohort 1 demonstrated elevated CSF progranulin levels to supraphysiologic levels at the lowest tested dose, Dose 1, up to six months post-treatment (n=1). Additionally, Dose 1 of PBFT02 continued to be generally well-tolerated in patients who received an enhanced steroid regimen for immunosuppression. In the first half of 2024, the company expects to complete dosing for Cohort 1 patients and report 6-month safety and biomarker data in the second half of 2024. Following the positive data, multiple GRN+ patients have been identified and are being evaluated for eligibility across seven clinical trial sites in Brazil, Canada, the United States and Europe.
  
  
• Expansion of PBFT02 into additional adult neurodegenerative indications: In response to the promising initial data for PBFT02 in FTD-GRN and evidence supporting progranulin's role in neurodegeneration, the company is currently evaluating the therapeutic potential of PBFT02 in additional indications, including FTD-C9orf72, ALS, and Alzheimer's disease. The company is preparing for regulatory discussions and expects to obtain regulatory feedback on the clinical pathway to treating FTD-C9orf72 and ALS patients with PBFT02 in 2H 2024.
  
  
• Robust balance sheet to support operations: The company's decision to focus resources on the exploration of PBFT02 in additional indications, while simultaneously pursuing potential out-licensing opportunities for clinical-stage pediatric programs in GM1 gangliosidosis, Krabbe disease and metachromatic leukodystrophy, provides sufficient cash runway into Q4 2025 to execute through critical value-inflecting milestones.
  
  
• Appointed Kathleen Borthwick as Chief Financial Officer, effective March 1, 2024: Ms. Borthwick previously served as the company's Senior Vice President, Finance and Interim CFO and brings 25 years of pharmaceutical and biotech strategic financial leadership experience.
