Project summary/abstract
Immune checkpoint inhibitors (ICI) transformed oncological care for multiple cancers. Yet, 80% of ICI patients

will eventually fail therapy. Colossal efforts are invested in overcoming ICI resistance. A promising candidate

is the gut microbiome which was associated with ICI clinical outcomes. I led a seminal clinical trial…
