In September 2014, the Company entered into an asset license and purchase agreement for the sale and license of ulimorelin (the “Lyric Agreement”), the former lead compound of Tranzyme, to Lyric Pharmaceuticals, Inc. (“Lyric”).  In October 2016, Lyric achieved a milestone under the Lyric Agreement, and accordingly, the Company will record $0.1 million in related milestone revenue during the fourth quarter of 2016.

In October 2016, the Company assigned its rights to certain non-core intellectual property acquired in the Merger with Tranzyme to GE Healthcare Dharmacon, Inc. (“GE”), formerly known as Open Biosystems, Inc.  In connection with the assignment, the Company’s existing license and marketing agreement with GE terminated and all future royalty payments payable from GE to the Company will cease.  In consideration for the assignment, the Company will receive a one-time payment of $0.5 million from GE.
