"We are pleased to announce the closing of the transaction with Pierre Fabre Laboratories who are committed to expanding the reach of tab-cel to patients in the U.S. and across the globe," said Pascal Touchon, President and Chief Executive Officer of Atara. "Atara’s priority is to now submit the tab-cel BLA filing package, while initiating our first clinical study with ATA3219, a potential best-in-class allogeneic off-the-shelf CD19 CAR T with unique features."

With the closing of the transaction, Atara will receive approximately USD 27 million in cash upfront and initial inventory purchase. Under the agreement, Atara has the potential to receive up to a total of USD 640 million and significant double-digit tiered royalties on net sales, including up to USD 100 million in potential regulatory milestones through BLA approval. In addition, Pierre Fabre Laboratories will reimburse Atara for expected tab-cel global development costs through the Biologics License Application (BLA) transfer, and purchase future tab-cel inventory through the manufacturing transfer date.

Substantially all tab-cel manufacturing, clinical, and regulatory activities are planned to transition from Atara to Pierre Fabre Laboratories at the time of BLA transfer.

Atara plans to submit the BLA to the U.S. Food and Drug Administration (FDA) for tab-cel for the treatment of post-transplant lymphoproliferative disease (PTLD) in the second quarter of 2024.
