Preclinical studies performed by veterinary surgeons in large animals showed that several types of tumors can be labeled with AngioStamp™.

Today, surgical tumor resection is the therapeutic method of choice for most cancers. The limitations of surgical intervention include difficult visual tumor delineation and micro-metastasis detection.
AngioStamp™ is a fluorescent probe that specifically targets αvβ3 integrin overexpressed in endothelial cells during tumor angiogenesis and in many tumors.


AngioStamp™ enables surgeons to better visualize tumors during surgery, with 2 major benefits:

  • Better tumor margin detection
  • Detection and resection of small tumors and metastases (otherwise invisible).

AngioStamp™ is under development in order to be used during surgery of several cancers; Ovarian and breast cancers, peritoneal carcinomatosis, melanoma, glioma and sarcoma.
