Item 1.02.     Termination of a Material Definitive Agreement.

 

On December 4, 2013, the License and Collaboration Agreement, dated February 5, 2010 (the “Agreement”), between Rigel Pharmaceuticals, Inc. (the “Company”) and AstraZeneca AB (“AZ”) was terminated pursuant to notice from AZ. Under the Agreement, AZ was responsible for conducting and funding all future development, regulatory filings, manufacturing and global commercialization of products containing the Company’s oral spleen tyrosine kinase (“SYK”) inhibitors. As previously disclosed, in June 2013, AZ announced the topline results from two Phase 3 clinical trials investigating fostamatinib, the first oral SYK inhibitor in development for rheumatoid arthritis (“RA”). Based on the totality of the results of the Phase 3 program in patients with RA, AZ informed the Company that it would not proceed with regulatory filings. As a result of the termination of the Agreement, all rights to fostamatinib revert to the Company.
