Pfizer collaborates with Cellectis

The two companies have entered into a global strategic collaboration to develop Chimeric Antigen Receptor T-cell (CAR-T) immunotherapies.

Pfizer will get exclusive rights to pursue development and commercialization of CAR-T therapies, in the field of oncology, directed at a total of fifteen targets selected by Pfizer. Both companies will work together on preclinical research and Pfizer will be responsible for the development and potential commercialization of any CAR-T therapies for the Pfizer-selected targets. Also, the agreement provides for a total of twelve targets selected by Cellectis. Both companies will work together on preclinical research on four Cellectis-selected targets and Cellectis will work independently on eight additional targets. Cellectis will be responsible for clinical development and commercialization of CAR-T therapeutics for the Cellectis-selected targets. Pfizer has right of first refusal to the four Cellectis-selected targets.

Cellectis will receive an upfront payment of $80 million, as well as funding for research and development costs associated with Pfizer-selected targets and the four Cellectis-selected targets within the collaboration. Cellectis is eligible to receive development, regulatory and commercial milestone payments of up to $185 million per Pfizer product. Cellectis is also eligible to receive tiered royalties on net sales of any products that are commercialized by Pfizer.

Additionally, Pfizer will be entering into an equity agreement to purchase approximately 10% of the Cellectis capital through newly issued shares at 9.25 Euro per share, pending Cellectis shareholder approval. Approval by two-thirds of the votes cast by voting Cellectis shareholders is required for the issuance. Shareholders of Cellectis representing 52.8% of its voting rights have already undertaken to vote in favor of the issuance. In the event the sale of equity is not approved by the Cellectis shareholders, Pfizer has the option to terminate the collaboration agreement.
