SanBio and Teijin to Terminate Licensing Agreement regarding SB623 for Stroke Treatment

Tokyo, Japan, February 14, 2018 --- SanBio and Teijin Limited jointly announced today that they would terminate the exclusive licensing agreement signed in 2009 regarding the development and marketing of SB623 for stroke treatment in Japan.

Marketing rights to SB623 in Japan revert to SanBio, which will continue developing SB623 for chronic stroke treatment. Teijin does not intend to sell its stock holding in SanBio for the time being.

Based on the original agreement, in 2012 Teijin began consulting with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) regarding regulatory strategy, in preparation for clinical trials of SB623 for chronic stroke treatment. SanBio supported Teijin in pursuing Japan regulatory authorization for clinical trial.

Through this process, in 2016 Teijin confirmed that clinical trials using SB623 in Japan would be possible, based on which both Teijin and SanBio began preparation for clinical trials aimed at early approval. Eventually, however, the development policies of the two companies diverged, so following prudent deliberations they determined to terminate their licensing agreement as of February 14, 2018.
