IMMUNOLOGY PORTFOLIO Conclusions • TFF2 is a naturally occurring anti - inflammatory peptide that is a key part of the inflammatory reflex. • TFF2 is a partial agonist for CXCR4, upregulates ApoE and suppresses the proliferation and expansion of myeloid progenitors, thus reducing MDSCs. • Overexpression of TFF2, either through transgenic or adenoviral expression, reduces the development of colorectal cancer (CRC) following AOM/DSS treatment. • mTFF2 - MSA (mTNX - 1700) peptide synergizes with PD1 blockade therapy to reduce tumor size and increase survival in two CRC syngeneic mouse models. • mTNX - 1700 synergizes with anti - PD1 blockade to increase survival and eradicate gastric cancer (GC) in advanced orthotopic and metastatic models. • mTNX - 1700 reduces the production of MDSC and promotes a T - cell rich microenvironment, inducing a 50 - fold increase in intratumor CD8+ T cells.
