"This IND clearance underscores our continued commitment to delivering novel and best-in-class therapies to patients with cancer with the utmost urgency," said Garo H. Armen, Ph.D., Chairman and CEO of Agenus. "AGEN2373 has unique binding properties and is designed to mitigate the toxicity observed with competitor molecules; we believe that this molecule has great potential for patients with cancer."

AGEN2373 is an investigational agent that has not been approved for any uses. Efficacy and safety have not been established.
