“This is an important collaboration with Bristol Myers Squibb to explore this novel and entirely oral combination in patients who have progressed following T-cell engaging therapy. This trial will also evaluate mezigdomide-selinexor plus dexamethasone in patients with relapsed/refractory multiple myeloma who need an effective alternative to T-cell therapies,” said Richard Paulson, MBA, President and Chief Executive Officer of Karyopharm. “Pre-clinical studies with selinexor and mezigdomide post T-cell mediated therapies provide a  scientific rationale for this novel combination to potentially prevent/reverse T-cell exhaustion and improve outcomes for more of these patients. We look forward to initiating the trial in the first half of 2024.”
