CAMBRIDGE, Mass., May 11, 2023 (GLOBE NEWSWIRE) -- Prime Medicine, Inc. (Nasdaq: PRME), a biotechnology company committed to delivering a new class of differentiated one-time curative genetic therapies, today reported financial results and provided business updates for the first quarter ended March 31, 2023.
“The first quarter and recent months were marked by a number of important milestones across our business as we execute against our mission of delivering a new class of one-time, potentially curative genetic therapies,” said Keith Gottesdiener, M.D., President and Chief Executive Officer of Prime Medicine. “We are particularly encouraged by recent progress across our diversified pipeline. Earlier this year, we nominated our first development candidate, PM359, and, at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting in May, we will showcase new preclinical data further supporting the potential of PM359 to correct the causative mutation of chronic granulomatous disease (CGD). Also at ASGCT, we will share new data demonstrating the power of our PASSIGE™ technology to generate CAR-T cells, potentially unlocking the opportunity for Prime Editing to address a number of cancers and immune diseases. Together, these presentations underscore our belief that Prime Editing is unrivaled in its breadth and potential to offer curative treatments for many diseases.”
Dr. Gottesdiener continued, “Additionally, we recently strengthened our corporate position with additions to our intellectual property portfolio. The recent patent issuance and patent application allowance mark a significant step toward our goal of securing the broadest intellectual property protection for our platform technology. We are also pleased to announce the appointment of Jeff Marrazzo to our Board of Directors. With his experience as co-founder and former Chief Executive Officer of a commercial gene therapy company, Jeff brings expertise and a unique perspective that we believe will complement the skills of our leadership team. We look forward to partnering with him as we pursue our shared vision of pushing the frontier of genetic medicine to deliver better outcomes to patients.”
Recent Business Updates
- Today, Prime Medicine announced that it will present preclinical data from its Prime Editing platform at the ASGCT 26th Annual Meeting, being held May 16-20, 2023 in Los Angeles. In an oral presentation, Prime Medicine will highlight new findings further demonstrating the potential of Prime Editing to correct the causative mutation of CGD and, in a poster presentation, will showcase the potential of the PASSIGE platform to multiplex edit CAR-T cells for the treatment of certain cancers and immune diseases. Details of the presentations are as follows:

Date & Time: Wednesday, May 17, 2023, 5:15 – 5:30 p.m. PT
Room: Room 515 AB
Session Title: Genome Editing Therapies & Safety I
Presenter: Jennifer Gori
Abstract Title: (602) An All-Prime Editing One-Step Approach for Non-Viral Generation of a Multiplex-Edited Allogeneic CAR-T Cell Product
Date & Time: Wednesday, May 17, 2023, 12:00 p.m. PT
Session Title: Wednesday Poster Session
Presenter: Emily Pomeroy
- In May 2023, Prime Medicine appointed Jeff Marrazzo, co-founder and former Chief Executive Officer of Spark Therapeutics, Inc., to its Board of Directors. Jeff founded and built Spark Therapeutics from an idea incubated within the Children’s Hospital of Philadelphia (CHOP) into the world’s first fully integrated, commercial gene therapy company with over 850 employees at the time of his departure. Under Jeff’s leadership, Spark developed and launched LUXTURNA® for a rare blinding disorder, the first U.S. Food and Drug Administration-approved gene therapy for a genetic disease in the U.S., spearheading the creation of novel reimbursement models to ensure patient access to genetic medicines. While at Spark, Jeff shepherded multiple gene therapies into the clinic for patients with conditions ranging from inherited retinal diseases to rare bleeding and neuromuscular disorders, raising $1 billion in capital and establishing major partnerships with Pfizer and Novartis. Jeff’s orchestration of Spark’s $4.8 billion sale to Roche in 2019 marked a 100-fold increase in the company’s market value over six years.
- In May 2023, the U.S. Patent and Trademark Office (PTO) issued Prime Medicine’s second patent, No. 11,643,652, which covers composition of matter for Prime Editor guide RNAs (PEgRNAs). In April 2023, Prime Medicine received a notice of allowance from the U.S. PTO for its third patent application, No. 17/751,599, which covers Prime Editing systems that include a PEgRNA, Prime Editor protein, and, optionally, a recombinase.
Anticipated Upcoming Milestones
Prime Medicine expects the following activities and next steps to drive the Prime Editing platform forward:
- Initiate investigational new drug (IND)-enabling studies for PM359 in CGD in 2023.
- Expand preclinical proof-of-concept in vivo data, with plans to share data from in vivo rodent studies and large animal studies from several programs in the second half of 2023.
- Share in vitro preclinical data in additional liver, eye and neuromuscular programs.
- Complete first IND filing as early as 2024 and additional IND filings anticipated in 2025.
- Continue to develop and optimize non-viral and viral delivery systems and share additional proof-of-concept data from in vivo rodent and large animal studies in the second half of 2023.
- Further demonstrate superior off-target profiles for Prime Editing programs.
- Expand Prime Editing using proprietary recombinase and/or retrotransposon technologies for new and existing programs.
- Maximize Prime Editing’s broad therapeutic potential and create value through strategic business development that extends the reach and impact of Prime Editing to areas beyond Prime Medicine’s current areas of focus.
First Quarter 2023 Financial Results:
- R&D Expenses: Research and development (R&D) expenses were $30.9 million for the three months ended March 31, 2023, as compared to $13.7 million for the three months ended March 31, 2022. This increase was primarily due to increases in lab supplies, personnel, and facilities costs as the company continues to expand and build out its R&D activities and function.
- G&A Expenses: General and administrative (G&A) expenses were $9.2 million for the three months ended March 31, 2023, as compared to $6.2 million for the three months ended March 31, 2022. This increase was primarily due to an increase in facility costs and professional costs primarily attributable to the build-out of the company’s G&A team to support business growth.
- Net Loss: Net loss was $39.4 million for the three months ended March 31, 2023, as compared to $23.8 million for the three months ended March 31, 2022.
- Cash Position: As of March 31, 2023, cash, cash equivalents, investments and restricted cash were $263.0 million, as compared to $307.4 million as of December 31, 2022.
Based on its current operating plans, Prime Medicine expects that its cash, cash equivalents and investments as of March 31, 2023 will be sufficient to fund its anticipated operating expenses and capital expenditure requirements into 2025.
About Prime Medicine
Prime Medicine is a leading biotechnology company dedicated to creating and delivering the next generation of gene editing therapies to patients.
