RIGEL PHARMACEUTICALS,INC. (NASDAQ:RIGL) Files An 8-K Entry into a Material Definitive Agreement
Item 1.01. Entry into a Material Definitive Agreement.

On January22, 2019, Rigel Pharmaceuticals,Inc. (“Rigel”) and Grifols Worldwide Operations Limited (“Grifols”) entered into an exclusive commercialization license agreement (the “Commercialization Agreement”) to commercialize fostamatinib disodium hexahydrate for the treatment, palliation, or prevention of human diseases, including chronic or persistent immune thrombocytopenia (“ITP”), autoimmune hemolytic anemia (“AIHA”), and IgA nephropathy in Europe and Turkey. The parties’ efforts will be governed through a joint steering committee and appropriate subcommittees established to guide and oversee the collaboration’s operation and strategic direction.

The Commercialization Agreement includes customary representations and warranties on behalf of Rigel as are customarily found in transactions of this nature, including representations and operative provisions as to the licensed intellectual property, regulatory matters and compliance with applicable laws. The Commercialization Agreement also provides for certain mutual indemnities for breaches of representations, warranties and covenants.

In consideration for the exclusive license and other rights contained in the Commercialization Agreement, Grifols will pay Rigel an upfront payment of$30.0 million. Rigel will be eligible to receive regulatory and commercial milestones of up to $297.5 million, which includes a $17.5 million payment for EMA approval of fostamatinib for the first indication, currently anticipated to be for the treatment of chronic ITP and a $2.5 million creditable advance royalty payment due upon EMA approval of fostamatinib in the first indication. Rigel will also receive tiered royalty payments ranging from the mid-teens to 30% of net sales of fostamatinib in Europe and Turkey. In return, Grifols will receive exclusive rights to fostamatinib for the treatment, palliation, or prevention of human diseases, including chronic or persistent ITP, AIHA, and IgA nephropathy, in Europe and Turkey. Grifols shall also receive an exclusive option to expand the territory to include the Middle East, North Africa and Russia (including Commonwealth of Independent States). Rigel retains the remaining global rights to fostamatinib outside the Grifols territories and those rights previously granted to Kissei Pharmaceuticals (in Japan, China, Taiwan and the Republic of Korea). Grifols will use diligent efforts to commercialize fostamatinib in countries where regulatory approval has been obtained.

Rigel will be responsible, and bear all associated costs and expenses, to (i)continue the extension portion of the phase 3 clinical trial for ITP currently on-going until marketing authorization application (“MAA”) approval or until such clinical trial is concluded, and, to the extent agreed by the parties, conduct any other clinical trials of fostamatinib for ITP required by the EMA to obtain MAA approval until MAA approval is obtained from the EMA and (ii)conduct the planned phase 3 clinical trial for AIHA, and, to the extend agreed by the parties, any other follow up clinical trials of the Product for AIHA required by the EMA to obtain MAA. Grifols will be responsible for all territory-specific development activities that are for the benefit of Europe and Turkey. As part of the collaboration, the parties will enter into a supply agreement to which Rigel will manufacture, by itself or through a third party contract manufacturer, and supply fostamatinib to Grifols on an exclusive basis.

The Commercialization Agreement may be terminated for cause byeither party based on regulatory reasons, uncured material breach by the other party, bankruptcy of the other party or for safety reasons. Rigel may terminate the agreement if Grifols challenges or opposes any patent covered by the Commercialization Agreement. After the first MAA approval of fostamatinib in Europe and Turkey, Grifols may terminate the Commercialization Agreement upon eighteen months’ prior written notice following the second anniversary of the first MAA approval of fostamatinib in Europe and Turkey. Grifols will also have the right to terminate the Commercialization Agreement for Rigel’s material breach of the supply agreement. If, by the second anniversary of the effective date of the Commercialization Agreement, the EMA has not approved the MAA for fostamatinib for ITP, Grifols will have the right to terminate the Commercialization Agreement in its entirety within six (6)months after such second anniversary by providing Rigel with at least sixty (60) days’ written notice, and in such event only, Rigel is required to refund to Grifols $25.0 million of the upfront payment. Upon termination by either party, all licenses granted by Rigel to Grifols will automatically terminate. In the case Rigel is in acquisition discussions with a competing company selling plasma products and Grifols has not provided its consent to an assignment or transfer of the Commercialization Agreement to such company in the event such an acquisition were to occur, in accordance with a certain process, then the Commercialization Agreement terminates if such an acquisition occurs, and Rigel or the acquiring party shall pay Grifols a one-time payment of $60.0 million.
