PASG Passage Bio Inc

Passage Bio, Inc. (Nasdaq: PASG), a clinical-stage genetic medicines company focused on developing transformative therapies for central nervous system (CNS) disorders, today provided an update on strategic priorities to extend its cash runway. The company will decrease operating expenses by reducing the workforce by approximately 13 percent and prioritizing its research and development programs in partnership with the University of Pennsylvania’s Gene Therapy Program (GTP). The company will continue to focus on advancing its three lead clinical programs for GM1 gangliosidosis, Krabbe disease and frontotemporal dementia.

“We are committed to our mission of developing transformative therapies for people with devastating CNS disorders,” said Bruce Goldsmith, Ph.D., president and chief executive officer, Passage Bio. “We have made the strategic decision to focus our organizational priorities, reduce our operating expenses and invest in the highest value development activities. By aligning our organization and our foundational partnership with GTP around a more focused R&D strategy, we are well-positioned to execute against our ongoing clinical trials and advance our mission.”

In conjunction with the headcount reduction, Eliseo O. Salinas, M.D., MSc, chief research and development officer, will be retiring and departing from the Company effective March 18, 2022. Mark Forman, M.D., Ph.D., chief medical officer, will continue to lead execution of the ongoing clinical trials. Dr. Forman joined the company in July 2021 with 20 years of experience in translational research for neurological disorders in both corporate and academic settings.

“While it will be difficult to part with these talented members of our team, we want to thank them for their important contributions to Passage as we continue to pursue our mission to deliver medicines that provide a cure for previously incurable diseases,” added Dr. Goldsmith.

• Dose first patient in Phase 1/2 study for FTD-GRN in early 2022. Additional clinical data milestone timing to be provided following dosing of first patients.
