We have a License Agreement with Allogene Therapeutics, Inc., according to which we granted to Allogene an exclusive, worldwide license to develop and commercialize CAR T-cell products directed at a total of 15 selected targets, including BCMA, FLT3, DLL3 and CD70, for human oncologic therapeutic, diagnostic, prophylactic and prognostic purposes. 


Up to $2.8B In Development & Sales Milestones ​+ High Single-Digit Royalties on Sales 

We have a License, Development and Commercialization Agreement with Les Laboratoires Servier, according to which Servier has an exclusive worldwide license to develop and commercialize gene-edited allogeneic CAR T-cell products targeting CD19, including ALLO-501 and ALLO-501A. The exclusive rights for the development and commercialization of such products in the United States have been sublicensed by Servier to Allogene (such rights having been previously held by Pfizer, Inc. and transferred to Allogene). 

In September 2022, Servier communicated that it was discontinuing its involvement in the development of in-licensed CD19 products and purporting to provide Allogene with the ability to elect to obtain a license to the CD19 Products outside of the United States. We are evaluating all available options and contractual remedies to address the foregoing matters and other performance issues, which we believe may involve material breaches of the Servier Agreement by Servier.
