Passage Bio, Inc. (Nasdaq: PASG), a clinical stage genetic medicines company, announced updated interim data from their ongoing Phase 1/2 upliFT-D clinical trial evaluating PBFT02 for the treatment of frontotemporal dementia (FTD) with granulin $(GRN)$ mutations. The company reported that PBFT02 continued to show robust and durable elevation in cerebrospinal fluid progranulin levels and improvement in plasma neurofilament light chain levels, a biomarker for disease progression. Passage Bio plans to amend the trial protocol to include a prophylactic course of low dose anticoagulation and modify inclusion criteria to study patients earlier in the disease progression. The company remains on track to seek regulatory feedback on the FTD-GRN pivotal trial design in the first half of 2026. Results from the study have already been presented, and further updates are anticipated.
