Phase III Study in Patients with Relapsed/Refractory Multiple Myeloma to compare the efficacy of plitidepsin in combination with dexamethasone vs. dexamethasone alone measured by progression-free survival (PFS) and to evaluate tumor response, duration of response (DR), overall survival (OS) and to rule out any effect of plitidepsin on the duration of the QT/QTc interval (time corresponding to the beginning of depolarization to re-polarization of the ventricles).
