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

Is NCT06484829 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including Purinostat Mesylate 4 mg/m2 and Purinostat Mesylate 6 mg/m2 for relapsed or refractory multiple myeloma (rrmm).

Phase 1/2RecruitingChengdu Zenitar Biomedical Technology Co., LtdNCT06484829Data as of May 2026

Treatment: Purinostat Mesylate 4 mg/m2 · Purinostat Mesylate 6 mg/m2 · Purinostat Mesylate 8.4 mg/m2Primary 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. To evaluate the safety and tolerability of Purinostat Mesylate for Injection combined with fixed-dose Pomalidomide Capsules and Dexamethasone in the treatment of relapsed or refractory multiple myeloma. 2. To assess the pharmacokinetic (PK) parameters of the combination therapy in patients with relapsed or refractory multiple myeloma. 3. To observe the preliminary efficacy of the combination therapy in patients with relapsed or refractory multiple myeloma. Phase IIa 1. To evaluate the preliminary efficacy of the combination therapy in patients with relapsed and refractory multiple myeloma (RRMM). 2. To characterize the population pharmacokinetic (PPK) profile of the combination therapy in patients with relapsed or refractory multiple myeloma (RRMM).
