Study of the Combination of Panobinostat and Carfilzomib in Patients With Relapsed/Refractory Multiple Myeloma

Found through the registry condition index, not selected as a treatment recommendation. This discovery collection was restricted to studies with posted results.

Phase: PHASE1, PHASE2
Status at capture: COMPLETED
Registry last update: 2022-02-02

Relapsed/refractory Multiple Myeloma (MM) is an incurable disorder with a poor prognosis. Carfilzomib is a novel proteasome inhibitor with activity in this setting. Panobinostat is a pan-deacetylase inhibitor which has shown synergistic cytotoxicity in vitro and in vivo with proteasome inhibitors. The combination should enhance the activity of both agents against myeloma cells. In Phase I, the optimal doses of the combination of carfilzomib and panobinostat will be determined. Assuming this combination is feasible, the Phase II portion will proceed using the doses determined in Phase I.

description
Using a traditional 3+3 dose escalation design, successive cohorts of subjects will receive a fixed dose level of the drug combination. The MTD is defined as the highest dose level at which ≤1 of 6 subjects experiences a dose-limiting toxicity (DLT) assessed by NCI CTCAE v4.0. DLT is defined as any of the following that are determined to be related to study treatment during Cycle 1: Grade 4 neutropenia for \>7 days, Febrile neutropenia, Grade 3 thrombocytopenia with ≥ Grade 2 bleeding, Grade 4 thrombocytopenia \> 7 days, ≥ Grade 2 neuropathy with uncontrolled pain, ≥ Grade 3 non-hematologic drug-related toxicity (excluding alopecia), despite optimal supportive care lasting \>72 hours or requiring a dose reduction in the first cycle and Patients who are unable to receive 75% of the required doses of both agents secondary to toxicity. Number of Participants With such Dose Limiting Toxicities (DLT) at each level are reported here.

Full study description

brief Summary: Relapsed/refractory Multiple Myeloma (MM) is an incurable disorder with a poor prognosis. Carfilzomib is a novel proteasome inhibitor with activity in this setting. Panobinostat is a pan-deacetylase inhibitor which has shown synergistic cytotoxicity in vitro and in vivo with proteasome inhibitors. The combination should enhance the activity of both agents against myeloma cells. In Phase I, the optimal doses of the combination of carfilzomib and panobinostat will be determined. Assuming this combination is feasible, the Phase II portion will proceed using the doses determined in Phase I.
detailed Description: In this open-label, non-randomized Phase I/II study, a maximum of 4 planned dose levels of carfilzomib and panobinostat were evaluated to determine the maximum tolerated dose (MTD) to administer. The MTD was not reached so patients in Phase II received treatment at dose level 4 to further assess efficacy. Response to treatment was evaluated after each 4-week cycle. Those having an objective response or stable disease are continuing treatment until disease progression or unacceptable toxicity occurs. As the MTD in the 4 planned dose levels were not reached, a parallel Phase I study was initiated to examine additional dose levels using a traditional 3+3 design. If these dose levels are tolerable, then more patients will be recruited into an expansion cohort to assess efficacy at the new dose level(s).
