Abstract

This phase 1 dose-escalation study evaluated pomalidomide, bortezomib (subcutaneous (SC) or intravenous (IV)) and low-dose dexamethasone (LoDEX) in lenalidomide-refractory and proteasome inhibitor-exposed relapsed or relapsed and refractory multiple myeloma (RRMM). In 21-day cycles, patients received pomalidomide (1-4 mg days 1-14), bortezomib (1-1.3 mg/m2 days 1, 4, 8 and 11 for cycles 1-8; days 1 and 8 for cycle ⩾9) and LoDEX. Primary endpoint was to determine the maximum tolerated dose (MTD). Thirty-four patients enrolled: 12 during escalation, 10 in the MTD IV bortezomib cohort and 12 in the MTD SC bortezomib cohort. Patients received a median of 2 prior lines of therapy; 97% bortezomib exposed. With no dose-limiting toxicities, MTD was defined as the maximum planned dose: pomalidomide 4 mg, bortezomib 1.3 mg/m2 and LoDEX. All patients discontinued treatment by data cutoff (2 April 2015). The most common grade 3/4 treatment-emergent adverse events were neutropenia (44%) and thrombocytopenia (26%), which occurred more frequently with IV than SC bortezomib. No grade 3/4 peripheral neuropathy or deep vein thrombosis was reported. Overall response rate was 65%. Median duration of response was 7.4 months. Pomalidomide, bortezomib and LoDEX was well tolerated and effective in lenalidomide-refractory and bortezomib-exposed patients with RRMM.

MM-005 trial design. MM-005 included 5 dose-escalation cohorts. Three patients were treated at each dose level, and 7 additional patients were treated at the MTD in the expansion phase of the trial. An additional cohort of patients treated with SC bortezomib (BORT) was included (n=12). Patients were evaluated every 21 days until treatment discontinuation. Patients will undergo long-term follow-up for OS and secondary primary malignancies (SPM). *For cycles 1–8, then D1 and D8 for cycle ⩾9. For cycles 1–8, then D1–2 and D8–9 for cycles ⩾9. 10 mg for patients aged >75 years. POM, pomalidomide.

Response outcomes. All treated patients were evaluated for response (better than or equal to PR). TTR and DOR were reported for patients who achieved response. BORT, bortezomib; CR, complete response; sCR, stringent complete response; VGPR, very good PR.
