DUBLIN and VANCOUVER, BC, June 17, 2026 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) and AbCellera (Nasdaq: ABCL) today announced a preclinical research collaboration, option and license agreement to discover and develop next-generation T-cell engaging (TCE) multispecific antibodies. The collaboration will leverage AbCellera's antibody discovery engine to deliver optimized development candidates for multiple gastrointestinal (GI) cancers and other solid tumors.

"This research collaboration with AbCellera directly aligns with Jazz's rare disease strategy, expanding our focus on GI cancers and building on our existing expertise in oncology," said Josh Allen, Ph.D., chief scientific officer, oncology, Jazz Pharmaceuticals. "We look forward to collaborating with AbCellera to progress potential best-in-class TCE multispecific antibodies for GI cancers and other solid tumors into clinical development and to develop meaningful innovation for patients."

AbCellera's T-cell engager platform is a fully integrated capability, from discovery to clinical manufacturing, for developing multispecific TCEs for difficult-to-treat cancers. The platform includes novel and proprietary panels of CD3-binding antibodies, costimulatory targeting arms, multispecific protein engineering technology, and a suite of high-throughput functional assays.

"Building on years of experience in TCEs, we are pleased to partner with Jazz Pharmaceuticals to leverage AbCellera's differentiated TCE platform to bring forward novel cancer treatments for GI cancers and other solid tumors," said Carl Hansen, Ph.D., founder and CEO of AbCellera. "TCEs drive highly targeted immune activation, which has the potential to significantly advance outcomes relative to existing treatments in these cancers."

Transaction Terms
Under the terms of the agreement, AbCellera will perform discovery and early-stage research activities for two initial programs with a commitment to start a third discovery program within 12 months. Jazz is granted an option in connection with each research program and, following exercise of its option and payment of an option fee, will have the exclusive, worldwide right to develop and commercialize each program. AbCellera will receive $56 million in total upfront payments for the first two research programs plus an additional $28 million due upon initiation of the third program. Should Jazz exercise its option for development, AbCellera is eligible to receive up to $792 million per program in option fees and development, regulatory, and commercial sales milestone payments along with tiered royalties on net sales ranging from mid-single digits to low double-digits. In addition, Jazz and AbCellera may mutually agree to initiate up to two additional programs, and to have AbCellera conduct certain activities for investigational new drug-enabling studies and manufacture clinical supply for any program under the collaboration.
