Passage Bio, Inc. entered into a lease termination agreement with Hopewell Campus Owner LLC on March 4, 2026, ending its lease for about 62,000 square feet of laboratory space in Hopewell. The lease, originally signed in December 2020, carried a 15‑year term starting in March 2021.
Under the termination agreement, Passage Bio will pay the landlord a termination fee of approximately $4.8 million plus accrued rent through February 14, 2026. The company had already ceased all operations at the Hopewell facilities following a restructuring in January 2025.
After this agreement, Passage Bio states it expects its cash and cash equivalents to fund operations through the first quarter of 2027, while cautioning that this estimate is based on assumptions that may change and could result in capital being used faster than anticipated.
Passage Bio files its annual report describing progress on PBFT02, a gene therapy for frontotemporal dementia caused by progranulin deficiency (FTD-GRN) and related neurodegenerative diseases. In a Phase 1/2 trial, Dose 1 of PBFT02 raised cerebrospinal fluid progranulin from below 3.0 ng/mL at baseline to means of 12.4 ng/mL at one month, 19.4 ng/mL at six months, 25.9 ng/mL at 12 months and 23.8 ng/mL at 18 months, above healthy control ranges. Plasma neurofilament light chain, a marker of neurodegeneration, increased 4% at 12 months versus natural-history increases of about 28–29%. Safety data showed treatment-related venous sinus thrombosis and hepatotoxicity at the higher dose, which were asymptomatic and responsive to treatment. The company is now enrolling a lower-dose Cohort 3, extending PBFT02 development into FTD with C9orf72 mutations, and positioning a higher-yield suspension manufacturing process with Catalent for late-stage trials. Passage Bio also highlights an HD program with Gemma Biotherapeutics targeting MSH3 to reduce somatic instability, plus orphan and Fast Track designations for PBFT02 in FTD.
Passage Bio reported fourth-quarter and full-year 2025 results and highlighted progress in its PBFT02 gene therapy program for frontotemporal dementia. The company enrolled the first three FTD-GRN patients in Cohort 3 and treated the first FTD-C9orf72 patient with Dose 2 PBFT02 in Cohort 4 of the upliFT-D study.
Net loss for 2025 was $45,522 thousand, narrowing from $64,767 thousand in 2024, as research and development expenses fell to $23,276 thousand from $40,179 thousand and general and administrative expenses declined to $19,875 thousand from $24,988 thousand. Cash and cash equivalents were $46,303 thousand at December 31, 2025, and the company projects a cash runway through the first quarter of 2027.
The upliFT-D Phase 1/2 trial continues to enroll FTD-GRN and FTD-C9orf72 patients, focusing primarily on safety and tolerability, with biomarker and clinical outcomes as secondary measures. Passage Bio plans updated interim safety and biomarker data and regulatory feedback on an FTD-GRN registrational trial design in the first half of 2026, and expects to select a clinical candidate for its Huntington’s program in the second half of 2026.
