AMG 386

AMG 386 is a peptibody that binds to and inhibits angiopoietin 1 and 2.  It is being investigated as a cancer treatment. AMG 386 has a new mechanism of action different from other anti-angiogenesis drugs: it inhibits angiogenesis by preventing interaction between angiopoietins and Tie2 receptor tyrosine kinases.  AMG 386 is being tested in combinations with many other drugs including sorafenib and sunittinib in Phase II trials.
