During 2016, the Company entered into a license agreement (the “Alba License”) with Alba Therapeutics Corporation (“Alba”) to obtain the rights to certain intellectual property relating to larazotide acetate and related compounds.
 
Upon execution of the Alba License, the Company paid Alba a non-refundable license fee of $0.5 million. In addition, the Company is required to make milestone payments to Alba upon the achievement of certain clinical and regulatory milestones totaling up to $1.5 million and payments upon regulatory approval and commercial sales of a licensed product totaling up to $150 million, which is based on sales ranging from $100 million to $1.5 billion.
 
During 2013, the Company entered into an exclusive license agreement with Seachaid Pharmaceuticals, Inc.

The Company was required to make an initial, non-refundable payment under the Seachaid Agreement in the amount of $0.2 million. The agreement also calls for milestone payments totaling up to $6.0 million to be paid when certain clinical and regulatory milestones are met.
