The Company has entered into various research, development, license and supply agreements with Takeda Pharmaceuticals Co. Ltd. (“Takeda”), Serum Institute of India (“Serum Institute”), Pharmsynthez and SynBio LLC (“SynBio”), a wholly owned subsidiary of Pharmsynthez. The Company and its collaborative partners continue to engage in research and development activities with no resultant commercial products through March 31, 2020. In October 2017, the Company granted to Takeda the right to grant a non-exclusive sublicense to certain patents related to the Company’s PolyXen technology that were previously exclusively licensed to Takeda in connection with products related to the treatment of blood and bleeding disorders. Royalty payments of approximately $57,000 earned on sales by the sublicensee during the fourth quarter of 2019 were recorded as revenue by the Company during the three months ended March 31, 2020. The Company’s policy is to recognize royalty payments as revenue when they are reliably measurable, which is upon receipt of reports from Takeda. The Company receives these reports in the quarter subsequent to the actual sublicensee sales. There were no remaining performance obligations and all other revenue recognition criteria were met. There were no amounts recognized under this sublicense agreement during the three months ended March 31, 2019. No amounts were recognized as revenue related to the Serum Institute, Pharmsynthez or SynBio agreements during the three months ended March 31, 2020 and 2019.
