PHILADELPHIA, March 03, 2022 (GLOBE NEWSWIRE) -- Passage Bio, Inc. (Nasdaq: PASG), a clinical-stage genetic medicines company focused on developing transformative therapies for central nervous system (CNS) disorders, today reported financial results for the fourth quarter and full year ended December 31, 2021 and provided recent business highlights.

“Our focus continues to be on executing across our three clinical programs, and we are pleased to report that we have already achieved one of our key goals with the dosing of the first patients in Cohorts 2 and 3 for the Imagine-1 clinical trial for GM1 gangliosidosis,” said Bruce Goldsmith, Ph.D., president and chief executive officer, Passage Bio. “We advanced to the additional cohorts following positive interim safety, biomarker and efficacy data for Cohort 1. We look forward to enrolling additional patients across all our clinical studies and providing more data throughout 2022, including initial biomarker and safety data from Cohorts 2 and 3 in Imagine-1 in the second half of the year.

“We are also excited to advance our robust and differentiated CNS pipeline in partnership with Penn’s Gene Therapy Program,” Dr. Goldsmith added. “We are employing a diversified portfolio strategy spanning pediatric and adult CNS indications, both rare and large, to create sustained value. Toward the end of last year, we announced the exercising of options for Canavan and Huntington’s Disease with the Gene Therapy Program, strengthening our pipeline to include nine programs in addition to our ongoing exploratory research programs in Alzheimer’s Disease and temporal lobe epilepsy. We look forward to sharing more information and data on our pipeline programs throughout 2022.”

Recent Highlights:

  • Imagine-1 for GM1 gangliosidosis and GALax-C for Krabbe Disease Highlighted at the 18th Annual WORLD Symposium in February:
    • Passage Bio presented new clinical data, including developmental gains, for Cohort 1 patients in the Imagine-1 clinical trial for GM1 gangliosidosis (GM1) in a late-breaking science presentation at the scientific conference. This presentation followed the positive interim safety and biomarker data first shared by the company in December 2021.
    • Podium presentations were also delivered on the clinical trial designs for Imagine-1 and GALax-C.
  • Dosed first patients in Cohorts 2 (late infantile, high dose) and 3 (early infantile, low dose) of the Imagine-1 clinical trial in early 2022: This followed an Independent Data Monitoring Committee (IDMC) recommendation to proceed in December 2021 following Cohort 1 interim data results.
  • Continuing to activate clinical sites in multiple countries to support three ongoing global clinical programs: To date, the company has activated clinical sites in the United States, Brazil, Canada, UK and Netherlands for its three clinical programs.
  • Expanded and further diversified CNS pipeline with two additional options with University of Pennsylvania’s Gene Therapy Program (GTP) in December 2021: Passage Bio enhanced its CNS pipeline with programs for Canavan and Huntington’s disease, bringing Passage Bio’s total licensed options to nine, alongside exploratory research programs in Alzheimer’s disease and Temporal Lobe Epilepsy. Under this strategic collaboration with GTP, Passage Bio’s pipeline includes five pediatric and four adult, monogenic CNS programs, three of which are currently in clinical development, and eight options remain.
