Altered Microenvironment In
Cancer and Fibrosis

Tumors and fibrotic disorders evade traditional therapies by changing the microenvironment, or stroma, in the diseased area. These changes result in hypoxia, increased local pressure, decreased drug uptake, and impaired immune response. Our therapies have the potential to normalize the stroma, reversing fibrosis and amplifying the impact of cancer therapies.



For XTuit, it’s all about patients, and they always come first. That’s why we’re striving for cures for people living with cancer and fibrotic diseases by developing innovative, microenvironment-targeted therapeutics.

The Company


Through a deep understanding of the biology of the microenvironment and how its dysregulation drives fibrotic diseases and certain cancers, we develop novel, specifically directed therapies that change outcomes for patients.
