Item 1.01. Entry into a Material Definitive Agreement


On July 24, 2018, Protalix BioTherapeutics, Inc. (the “Company”) issued a press release announcing that the Company’s wholly-owned subsidiary, Protalix Ltd. (“Protalix”), entered into an Exclusive License and Supply Agreement, dated July 23, 2018 (the “U.S. License Agreement”), with Chiesi Farmaceutici S.p.A. (“Chiesi”), to develop and commercialize in the United States pegunigalsidase alfa, or PRX-102, the Company’s chemically modified version of the recombinant protein alpha-Galactosidase-A protein that is currently being evaluated in phase III clinical trials for the treatment of Fabry disease. As announced in October 2017, Protalix and Chiesi are parties to a separate exclusive license and supply agreement, pursuant to which Protalix granted to Chiesi exclusive licensing rights for the commercialization of PRX-102 for all markets outside of the United States.


Under the terms of the U.S. License Agreement, Protalix is entitled to an upfront, non-refundable, non-creditable payment of $25 million from Chiesi, and additional payments of up to a maximum of $20 million to cover Protalix’s development costs for PRX-102, subject to a maximum of $7.5 million per year. Protalix is also eligible to receive an additional up to a maximum of $760 million, in the aggregate, in regulatory and commercial milestone payments.


Protalix and Chiesi have agreed to a specific allocation of the responsibilities for the continued development efforts for PRX-102. Protalix will manufacture all of the PRX-102 needed for clinical development and commercial purposes, subject to certain exceptions, and Chiesi will purchase PRX-102 from Protalix, subject to certain terms and conditions. Chiesi will make tiered royalty payments of 15% to 40% on net sales, depending on the amount of annual sales subject to certain terms and conditions, as consideration for product supply. The U.S. License Agreement also provides for reimbursement by Chiesi of certain costs to be incurred by Protalix.


The U.S. License Agreement includes customary termination, confidentiality, indemnification and other provisions. The foregoing description of the U.S. License Agreement does not purport to be complete and is qualified in its entirety by the U.S. License Agreement, a copy of which the Company intends to file as an exhibit to the Company’s periodic reports.
