ICI is approved and used in the treatment of various cancers. However, some carcinomas are refractory to ICI and the treatment effect diminishes through drug resistance. Adenosine-induced tumor progression and drug resistance are major obstacles to ICI therapy. Effective removal of adenosine surrounding the tumor can improve the ICI effect and suppress tumor progression.
"We are excited to present our in vitro cell analysis results at AACR (Free AACR Whitepaper), that support EC-18’s unique mechanism of action and synergistic therapeutic effect in combination with immune checkpoint inhibitors," said Ki Young Sohn, CEO & Chairman, Enzychem Lifesciences. "Based on these results, EC-18 has an anti-tumor effect by quickly eliminating eAdo extracellular adenosine (eAdo), which is a key factor for successful ICI therapy. PLAG, the active pharmaceutical ingredient of EC-18, may help cancer cells absorb and remove eAdo, thereby, effectively inhibiting tumor growth and changing the tumor microenvironment. PLAG may enhance the therapeutic effect of ICI in the treatment of LLC-1 lung carcinoma cells."
