Jazz Pharmaceuticals and AbCellera Announce Collaboration to Discover Next-Generation T-cell Engaging Multispecific Antibodies

Key Terms

t-cell engaging medical

T-cell engaging describes a type of drug or therapy designed to recruit a patient’s own T cells—immune cells that seek and destroy infected or abnormal cells—toward a specific target, such as a tumor or infected cell. Think of it as a matchmaker that brings the immune attacker to the target; for investors, this approach can mean strong therapeutic effects and high market value but also heightened safety concerns and tighter regulatory scrutiny.

multispecific antibodies medical

Multispecific antibodies are engineered immune proteins designed to bind two or more different targets at the same time, like a multitool that can grab several distinct screws in one go. For investors, they matter because combining multiple actions in a single drug can improve effectiveness, reduce side effects, or replace combination therapies, which can speed development, broaden potential markets, and affect a drug candidate’s commercial and regulatory prospects.

cd3-binding antibodies medical

CD3-binding antibodies are engineered proteins that attach to the CD3 unit on T cells, the immune system’s attack cells, and thereby trigger or redirect those T cells to recognize and kill specific diseased cells. They matter to investors because this mode of action underlies several high-value immunotherapy drugs: successful candidates can create significant revenue if safe and effective, while failures can face safety, manufacturing and regulatory hurdles that materially affect a company’s valuation.

investigational new drug regulatory

An investigational new drug is a medication that is still being tested in clinical trials to determine if it is safe and effective for treating a specific condition. For investors, it represents a potential breakthrough that could lead to a new treatment and significant financial gains if successful, but also carries risks since it has not yet been approved for widespread use.

The collaboration includes $56 million in upfront payments to AbCellera and up to $792 million in potential option fees and milestone payments for any program Jazz exercises its option to develop

Jazz has the exclusive option to develop and commercialize therapeutic antibodies resulting from the collaboration

DUBLIN & VANCOUVER, British Columbia--(BUSINESS WIRE)-- 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.
