Purinostat Mesylate Combined With Pomalidomide Capsules and Low-dose Dexamethasone in Patients With Relapsed or Refractory Multiple Myeloma

Summary

Primary Purpose Phase Ib. To determine the Maximum Tolerated Dose (MTD) and establish the Recommended Phase IIa Dose (RP2D) of Purinostat Mesylate for Injection combined with fixed-dose Pomalidomide Capsules and Dexamethasone in patients with relapsed or refractory multiple myeloma. Phase IIa. To further evaluate the safety and tolerability of Purinostat Mesylate for Injection at the RP2D combined with fixed-dose Pomalidomide Capsules and Dexamethasone in patients with relapsed and refractory multiple myeloma (RRMM). Secondary Objectives Phase Ib 1.
