PHILADELPHIA, May 11, 2020 (GLOBE NEWSWIRE) -- Passage Bio, Inc. (Nasdaq: PASG), a genetic medicines company focused on developing transformative therapies for rare, monogenic central nervous system disorders, today reported financial results for the first quarter ended March 31, 2020 and provided recent business highlights.

“The first quarter was a significant time for Passage Bio and the patients that we serve. Building upon the strong momentum since launching the company in 2018, we completed an upsized IPO in March 2020 and are now working to bring our lead program, PBGM01, for the treatment of infantile GM1 gangliosidosis into the clinic as soon as possible and advancing the balance of our deep pipeline,” said Bruce Goldsmith, Ph.D., president and chief executive officer of Passage Bio. “While the potential impacts of the COVID-19 pandemic are uncertain, with our deeply experienced management team, supported by a strong cash position, we are confident in our ability to continue to execute and remain on-track to meet our 2020 clinical development goals. As a company that aims, above all, to serve patients and families suffering from rare, life-threatening CNS diseases with no alternative treatment options, we are committed to driving our programs forward.”

Recent Business Highlights

• Expansion of gene therapy collaboration with the University of Pennsylvania (UPenn) – In May 2020, Passage Bio expanded its research and development collaboration and licensing agreement with UPenn. The amendment increased the number of remaining available licensing options for programs to treat rare monogenic CNS disorders from from six to eleven and extended the window for the exercise of options by three years. Accordingly, the window to exercise all eleven remaining options extends to May 2025. The company also received exclusive rights and licenses, subject to limitations, to certain technologies resulting from discovery research at Gene Therapy Program (GTP) for Passage Bio products developed with GTP, such as novel capsids, toxicity reduction technologies and delivery and formulation improvements.
• Granted Orphan Drug Designation (ODD) by the U.S. Food and Drug Administration (FDA) for the lead product candidate PBGM01 – In April 2020, the FDA granted ODD to PBGM01 for the treatment of infantile GM1 gangliosidosis (GM1), a rare and often life-threatening monogenic recessive lysosomal storage disease caused by mutations in the GLB1 gene that results in rapidly progressing neurodegeneration. The designation grants the company certain benefits, including financial incentives to support clinical development and the potential for up to seven years of market exclusivity in the U.S. upon regulatory approval.
• Completed upsized Initial Public Offering (IPO) – In March 2020, Passage Bio completed its IPO of 13,800,000 shares of common stock at a public offering price of $18.00 per share, including an exercise of the underwriter’s option to purchase additional shares. The total net proceeds from the offering, after deducting underwriting discounts, commissions and offering expenses, were $227.5 million.
• Appointed Bruce Goldsmith, Ph.D. as president and chief executive officer – In January 2020, Passage Bio announced the appointment of Bruce Goldsmith, Ph. D., as president and chief executive officer, succeeding co-founder and interim chief executive officer Stephen Squinto, Ph.D., who now serves as acting head of research and development for the company.
• Strengthened company’s Board of Directors (BOD) with additions of Sandip Kapadia and Athena Countouriotis, M.D. – In January and March 2020 respectively, Passage Bio appointed Sandip Kapadia, MBA, CPA, and Athena Countouriotis, M.D., to its BOD. Mr. Kapadia currently serves as the chief financial officer and treasurer of Intercept Pharmaceuticals, and Dr. Countouriotis is currently president and chief executive officer at Turning Point Therapeutics.

Anticipated Upcoming Milestones

• Initiate a Phase 1/2 trial for the lead program, PBGM01, for the treatment of patients with infantile GM1 in fourth quarter of 2020.
• Continue to advance the lead programs PBFT02, for the treatment of frontotemporal dementia (FTD) and PBKR03, for the treatment of Krabbe disease toward clinical study initiation in the first half of 2021.
• Continue to advance PBML04, PBLA05 and PBCM06 toward Investigational New Drug (IND)-enabling studies.

First Quarter 2020 Financial Results

• Cash Position: Cash and cash equivalents were $366.8 million as of March 31, 2020 as compared to $158.9 million as of December 31, 2019. In February 2020, Passage Bio raised $227.5 million in net proceeds from its IPO.
• Research and Development (R&D) Expenses: R&D expenses were $13.1 million for the quarter ended March 31, 2020, compared to $3.0 million for the quarter ended March 31, 2019. The increase was primarily due to an increase of $4.8 million in R&D costs incurred with Penn and were related to the preparation of several IND filings as well as an increase in other research costs of $2.9 million as the company prepares for its clinical trials to begin in the second half of 2020 and early 2021. The company also had a $2.3 million increase in personnel‑related costs and a $0.2 million increase in facility and other costs due to increases in employee headcount in the R&D function.
• General and Administrative (G&A) Expenses: G&A expenses were $4.8 million for the quarter ended March 31, 2020, compared to $1.2 million for the quarter ended March 31, 2019. The increase was primarily due to a $2.2 million increase in personnel-related and share‑based compensation expense due to increases in employee headcount. The company’s professional fees and facility costs also increased by $0.6 million and $0.8 million, respectively, as Passage Bio expanded its operations to support its R&D efforts.
• Net Loss: Net loss was $17.6 million, or a net loss of $1.00 per basic and diluted share, for the quarter ended March 31, 2020, compared to $7.7 million, or a net loss of $1.83 per basic and diluted share, for the quarter ended March 31, 2019.
