Agios Pharmaceuticals, Inc. announced that its collaboration partner Celgene Corporation has agreed that it will exercise its option to obtain an exclusive license outside the United States for AG-120, a first-in-class, oral, potent inhibitor of the mutant IDH1 protein under the terms of the 2010 collaboration agreement. This would be the second IDH mutant inhibitor to be licensed by Celgene in less than a year. AG-120 is currently being evaluated in two Phase 1 dose escalation trials, one in advanced hematologic malignancies and the other in advanced solid tumors.

Both trials are evaluating AG-120 in patients whose cancer harbors an IDH1 mutation.
