Item 8.01 Other Events.


Letter Agreement with Servier IP UK Limited


On January 30, 2019, Enzon Pharmaceuticals, Inc. (the “Company”) entered into a letter agreement with Servier IP UK Limited (“Servier IP UK”), a wholly owned indirect subsidiary of Les Laboratoires Servier, in connection with the asset purchase agreement, dated as of November 9, 2009 (the “Asset Purchase Agreement”), by and between Klee Pharmaceuticals, Inc., Defiante Farmacêutica, S.A. (“Defiante”) and Sigma-Tau Finanziaria S.p.A., on the one hand, and the Company, on the other hand. Under the letter agreement, Servier IP UK, as successor-in-interest to Defiante, has confirmed its obligation to pay the Company a $7.0 million milestone payment related to SC Oncaspar as a result of the U.S. Food and Drug Administration’s December 20, 2018 approval of calaspargase pegol – mkn (brand name ASPARLAS™) as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia in pediatric and young adult patients age 1 month to 21 years. In addition, under the letter agreement, the Company has agreed to waive Servier IP UK’s obligations to pursue the development of SC Oncaspar in Europe and the approval of SC Oncaspar by the European Medicines Agency (“EMEA”) under the Asset Purchase Agreement, provided that the Company is not waiving Servier IP UK’s obligation to make any applicable milestone payment to the Company upon EMEA approval, if any, of SC Oncaspar. Servier IP UK is required to pay the $7.0 million milestone payment to the Company within three business days following the parties’ completion of procedures for claiming benefits under the double tax treaty between the United States and the United Kingdom. The Company expects to receive the $7.0 million milestone payment from Servier IP UK by the third quarter of 2019. However, no assurance can be given as to the timing of the Company’s receipt of the payment.
