37 Addendum

38 Additional Assets • Fred Hutchinson will provide up to six new projects per year for five years as potential ground - breaking cancer treatment or diagnostics options for license to BeyondSpring. • Ubiquitination Technology: One approach is using a “molecular glue” to bind ubiquitin ligase to the target E3 ligase for oncogenes; collaborating with Dr. Zheng, HHMI Investigator, University of Washington. Fred Hutchinson Collaboration • BPI - 002: A small molecule co - stimulation agent that activates CD4 and CD8 T cells; can be alternative to CTLA - 4 inhibitors, when combined with PD1/PD - L1 inhibitors. • BPI - 004: A small molecule that induces neoantigens (immunogens) in tumors that previously were not immunogenic. More than 50% of human cancers are not immunogenic and therefore do not respond to PD1/PD - L1 inhibitors. By making these tumors immunogenic with BPI - 004, these cancers become responsive to PD1/PD - L1 inhibitors. IO – Internal Assets
