About BRB-002
BRB-002 is a novel protein therapy that is being evaluated as an investigational agent in atherosclerotic cardiovascular disease (ASCVD).  BRB-002 is an immuno-modulatory agent that inhibits the CD47 cell surface receptor (“don’t eat me” signal) to ameliorate the underlying causes of atherosclerosis and reduce inflammatory plaque burden. A Phase 1 clinical study of BRB-002 was completed by Bitterroot Australia Pty Ltd, a wholly owned subsidiary of Bitterroot Bio, Inc.
