PBFT02 Program Updates
On September 16, 2024, the Company announced updated interim safety and biomarker data from Cohort 1 patients who received Dose 1 of PBFT02 from the Company’s ongoing global Phase 1/2 clinical trial, upliFT-D, evaluating PBFT02, an adeno-associated virus-delivery gene therapy for the treatment of patients aged 35 to 75 years with frontotemporal dementia caused by progranulin deficiency, or FTD-GRN.
| ● | PBFT02 was well-tolerated in all patients (patients 2, 3, 4 and 5) who received an enhanced immunosuppression regimen following protocol amendment, as of August 20, 2024. |
| ● | PBFT02 resulted in increased progranulin (“PGRN”) levels in the cerebral spinal fluid (“CSF”) in all patients, relative to baseline, with up to a 6-fold increase at one month (range of 10.7 to 17.3 ng/mL; n=5) and up to a 10-fold increase at six months (range of 21.7 to 27.3 ng/mL; n=2). |
| ● | The effect of PBFT02 was consistent across all patients, with CSF PGRN levels exceeding the range found in healthy adult controls of 3.3 to 8.2 ng/mL (n=61). |
| ● | CSF PGRN remained elevated at 12 months (n=1), reaching a level of 34.2 ng/mL. The rate of increase was 58% between one month and six months and slowed to 26% between six months and twelve months. |
| ● | Plasma PGRN expression remained below healthy reference levels across all patients. |
