Karyopharm has entered into a royalty agreement worth up to $150 million to back the launch of their multiple myeloma drug ? recently approved by the FDA over the objections of a majority of the agency?s outside experts.
The deal with HealthCare Royalty Partners, worth $75 million now and $75 million once certain regulatory and commercial milestones have been reached, will fund the commercialization of Karyopharm?s oral SINE compound Xpovio (selinexor) for patients with multiple myeloma who have already had at least four prior therapies. The money will help Karyopharm as it markets its newly approved drug and pushes through clinical trials testing the drug on refractory multiple myeloma patients with one to three therapies and patients with treatment-resistant diffuse large B-cell lymphoma. It will give Karyopharm a cushion through mid-2021.
