who had responded to high-dose therapy and autologous stem cell transplant.
The drug’s sponsor, Takeda, announced that the oral proteasome inhibitor had met the primary endpoint – progression-free survival versus placebo – in the randomized, phase 3 TOURMALINE-MM3 study. They also reported that adverse events were consistent with previously reported results for single-agent use of ixazomib and that there were no new safety signals.
Full study results will be presented at the annual meeting of the American Society of Hematology. Company officials plan to submit the trial data to the Food and Drug Administration and regulatory agencies around the world to gain approval of ixazomib as a single-agent maintenance therapy, according to a Takeda announcement.
The TOURMALINE-MM3 study is a double-blind study of 656 patients with multiple myeloma who have had complete response, very good partial response, or partial response to induction therapy followed by high-dose therapy and autologous stem cell transplant. In addition to progression-free survival, the trial assessed overall survival.
