Item 1.01      Entry into a Material Definitive Agreement.


The Company and Zealand Pharma A/S (“Zealand”) entered into a collaboration agreement in June 2012 (the “Collaboration Agreement”). In October 2013, Zealand abandoned the collaboration, and the collaboration agreement was terminated in 2014. The abandonment of the collaboration was memorialized in an Abandonment Agreement dated as of February 28, 2014 (the “Abandonment Agreement”). The Collaboration Agreement provides for certain post-termination payment obligations to Zealand with respect to compounds related to the collaboration that meet specified conditions set forth in the Collaboration Agreement and which the Company elects to further develop following Zealand’s abandonment of the collaboration. Those obligations include development and sales milestone payments, as well as low-single digit royalties on net sales. The Company initially understood rusfertide to be a compound for which the post-termination payments described above are required under the Collaboration Agreement and therefore made three development milestone payments for an aggregate amount of $1.0 million under the Collaboration Agreement. However, upon re-evaluation, the Company concluded in 2019 that rusfertide is not a compound requiring post-termination payments under the agreement, and in 2020 initiated International Chamber of Commerce arbitration proceedings with Zealand related to the matter (the “Arbitration”).


The Company and Zealand resolved their dispute pursuant to an Arbitration Resolution Agreement, dated as of August 4, 2021 (the “Agreement”). Pursuant to the Agreement:


  a) the royalty rate payable by the Company on net sales of rusfertide has been reduced by 50%;


  b) all sales milestone payments on net sales of rusfertide have been reduced by 50%;


  c) all development milestones in respect of rusfertide have been reduced by 50%, except that the Company has agreed to pay in full within 2 business days after the effective date of the Agreement: (i) a $1.0 million development milestone for commencement of a Phase 2b rusfertide trial; and (ii) a $1.5 million development milestone that would otherwise have been due on initiation of a rusfertide Phase 3 trial (which trial the Company current expects to initiate in the first quarter of 2022).


  d) the Company is required to make an additional $1.5 million payment to Zealand in August 2022;


  e) each party will retain all payments previously made to it by the other party in connection with the Collaboration Agreement; and


  f) the parties have released claims related to the Collaboration Agreement, the Abandonment Agreement and the Arbitration.


Royalties, development milestone payments and sales milestone payments are due in respect of net sales and development made or achieved by either the Company or a Company licensee or collaborative partner. The Agreement relates only to rusfertide and not to any other compounds.


In addition to the payments specified in items (c) and (d) above, the Company expects, based on the anticipated number of patients in the rusfertide Phase 3 trial for polycythemia vera, that it may be required to pay Zealand up to $2.75 million in future rusfertide development milestone payments. Those payments include up to $1.0 million in the aggregate for registrational approvals (such as a New Drug Application approval by the United States Food and Drug Administration) and up to $1.75 million in the aggregate for commercial launch in the three geographic territories specified in the Collaboration Agreement (the United States, the European Union and the rest of the world, or “ROW”).


The reduced one-time sales milestone payments for rusfertide include up to an aggregate of $50 million based upon achievement of specified fiscal year net sales thresholds for the various territories.


The Company and Zealand have agreed to dismiss the Arbitration with prejudice, with each party bearing its own fees and costs.


The description of the terms and conditions of the Agreement set forth herein is not complete and is qualified in its entirety by reference to the text of the Agreement, which the Company intends to file as an exhibit to its Quarterly Report on Form 10-Q for the fiscal quarter ending September 30, 2021 and is incorporated herein by reference.







Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
