• Payment includes $9.75 million cash and $3.25 million in Imugene Limited ordinary shares
• The addition of this cash further reinforces Precision’s expected cash runway into the second half of 2026

DURHAM, N.C. / Sep 03, 2024 / Business Wire / Precision BioSciences, Inc. (Nasdaq: DTIL), an advanced gene editing company utilizing its novel proprietary ARCUS® platform to develop in vivo gene editing therapies for sophisticated gene edits, including gene elimination, gene insertion, and gene excision, today announced maturity of a $13 million convertible note from its previously announced strategic transaction with Imugene Limited (ASX: IMU) for azercabtagene zapreleucel (azer-cel) in oncology. The proceeds to Precision BioSciences include $9.75 million in cash and $3.25 million in Imugene ordinary shares.

“We are pleased that Imugene continues to advance azer-cel toward a pivotal trial in LBCL for patients with significant unmet need,” said Michael Amoroso, President and Chief Executive Officer of Precision BioSciences. “This marks one year since our strategic decision to focus our in-house programs exclusively on in vivo gene editing and further bolsters our balance sheet, enabling us to generate Phase 1 clinical data across multiple in vivo gene editing programs starting in the first half of 2025. In the near term, we are focused on progressing our pipeline towards the clinic and remain on track to file applications with multiple global regulatory bodies for PBGENE-HBV for chronic hepatitis B later this year.”

In August 2023, Precision announced a strategic transaction with Imugene. Under the agreement, Imugene assumed global rights to azer-cel for cancer, the ongoing clinical execution for azer-cel in large B-cell lymphoma (LBCL) patients who have relapsed following autologous CAR T treatment as well as Precision BioSciences’ CAR T capability, including manufacturing. In exchange, Precision received upfront economics valued at $21 million (all figures in USD) consisting of $8 million in cash and a $13 million convertible note. The convertible note matured on August 30, 2024 and resulted in payment to Precision of $9.75 million in cash and $3.25 million in Imugene stock. Precision is also eligible for additional payments based on azer-cel clinical milestones as well as milestones for other future nominated cancer research programs.

As of June 30, 2024, Precision had approximately $123.6 million in cash and cash equivalents, prior to receipt of the payment from Imugene. Existing cash and cash equivalents, upfront and potential near-term cash from CAR T transactions, along with expected operational receipts, continued fiscal and operating discipline, availability of Precision’s at-the-market (ATM) facility, and marketable securities are expected to extend Precision’s cash runway into the second half of 2026.

About Precision BioSciences, Inc.

Precision BioSciences, Inc. is an advanced gene editing company dedicated to improving life (DTIL) with its novel and proprietary ARCUS® genome editing platform that differs from other technologies in the way it cuts, its smaller size, and its simpler structure. Key capabilities and differentiating characteristics may enable ARCUS nucleases to drive more intended, defined therapeutic outcomes. Using ARCUS, the Company’s pipeline is comprised of in vivo gene editing candidates designed to deliver lasting cures for the broadest range of genetic and infectious diseases where no adequate treatments exist. For more information about Precision BioSciences, please visit www.precisionbiosciences.com.

The ARCUS® platform is being used to develop in vivo gene editing therapies for sophisticated gene edits, including gene insertion (inserting DNA into gene to cause expression/add function), elimination (removing a genome e.g. viral DNA or mutant mitochondrial DNA), and excision (removing a large portion of a defective gene by delivering two ARCUS nucleases in a single AAV).
