However, the results with se- linexor alone were more modest, with just 4 percent of patients responding to treatment. The small study, led by Christine Chen, MEd, MD, from the Princess Margaret Cancer Centre in Toronto, Ontario, assessed the safety, efficacy, and recommended maximum tolerated dose (MTD) of selinexor with or without dexamethasone in adult patients with relapsed/refractory myeloma (n=81) or Waldenström macroglobulinemia (WM; n=3). This was conducted as part of a larger, multicenter, dose-escalation, phase I study assessing selinexor in pati
