Karyopharm Announces Expansion Of Royalty Agreement With Healthcare Royalty For Up To $100 Million

NEWTON, Mass. – Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies,  announced the expansion of its royalty agreement with entities managed by HealthCare Royalty Management, LLC (HCR) for up to $100 million in new financing to support the ongoing development and commercialization of XPOVIO® (selinexor), the Company’s first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound, and for the clinical development of Karyopharm’s other programs, including eltanexor. XPOVIO is currently marketed in the U.S. for multiple hematologic malignancy indications and has received conditional marketing authorization by the European Commission for patients with heavily pretreated multiple myeloma. Eltanexor is currently being investigated for the treatment of patients with refractory myelodysplastic syndrome.

Under the terms of the amended agreement, Karyopharm received $60 million and is eligible to receive two additional $20 million payments subject to certain prespecified future development and commercial milestones. HCR will receive tiered royalty payments based on worldwide net revenues of XPOVIO and any other future products. This expanded agreement follows a previous investment of $75 million that HCR made in Karyopharm in September 2019.

Karyopharm expects that the $60 million received from HCR under this expanded royalty agreement, combined with its existing cash, cash equivalents and investments, and the cash expected to be generated from product sales, will be sufficient to fund its operations into the middle of 2023.

“We are thrilled to expand our relationship with HCR and this additional non-dilutive financing provides Karyopharm with immediate and substantial capital to support the ongoing commercialization and clinical development of XPOVIO and our other products in future cancer indications, including in a variety of high unmet need solid tumor settings,” said Richard Paulson, MBA, President and Chief Executive Officer of Karyopharm.  “As we continue to make progress on our commercialization efforts, we are delighted to have the support and confidence of HCR to further expand our clinical development efforts on behalf of patients across the globe.”

Clarke Futch, Chairman and Chief Executive Officer of HCR stated: “Based on the strong relationship we have built with the Karyopharm team over the past few years and our increasing confidence in the long-term potential for XPOVIO, we are delighted to broaden our investment in Karyopharm and further support the expansion of XPOVIO, including into solid tumors.”
