Clinical Trial Summary

The combination of lenalidomide plus low-dose dexamethasone (Rd) is considered the new standard for elderly newly diagnosed multiple myeloma (NDMM) patients. The combination carfilzomib plus lenalidomide-dexamethasone (KRd) in relapsed-refractory MM patients improved the progression-free survival (PFS) of approximately 1 year compared to standard Rd treatment. In a small phase 2 trial (23 pts) the KRd combination in elderly NDMM pts showed a complete response (CR) rate of 79% and a PFS at 3 years of 80%. Cardiovascular adverse events are the most limiting toxicities, especially in elderly patients.

Description:

This protocol is a randomized, multicenter study designed to determine the MRD negativity and the PFS of KRd treatment regimen.

Patients will be randomized in a 1:1 ratio to receive carfilzomib-lenalidomide-dexamethasone (KRd - Arm A) or lenalidomide-dexamethasone (Rd - Arm B).

Patients will be stratified basing on international staging system (ISS) and fitness status using a web-based procedure completely concealed to study participants.

All consecutive patients ≥ 65 years with newly diagnosed MM will be enrolled in a large randomized study during a period of 24 months.

Patients will be treated until disease progression or intolerance to the therapy. The only exception is for patients enrolled in KRd arm who achieve at least a VGPR during the first year of treatment and in sustained MRD negativity (MRD negative at least at 10-5 after one and two years of therapy): these patients will stop carfilzomib administration after 2 years, whereas treatment with lenalidomide and dexamethasone will be continued.

Intervention

Drug:
• Carfilzomib
20 mg/m2 IV on day 1 of cycle 1 enhanced to 56 mg/m2 on days 8, and 15 of cycle 1; 56 mg/m2 IV on days 1, 8 and 15 in cycles 2-12; 56 mg/m2 IV on days 1 and 15 from cycle 13 and onwards.
• Lenalidomide
- 25 mg orally on days 1-21 of each cycle.
• Dexamethasone
- 40 mg orally on days 1, 8, 15 and 22 of each cycle. Each cycle is to be repeated every 28 days. Patients that achieve at least a VGPR within the first year of study treatment and in sustained MRD negativity (MRD negative at least at 10-5 after 1 and 2 years of therapy) will stop carfilzomib administration after 2 years and will continue with lenalidomide and dexamethasone treatment until disease progression or intolerance to the therapy. Other patients will continue carfilzomib administration until disease progression or intolerance. For patients >75 years of age, the dose of dexamethasone is 20 mg/day on Days 1, 8, 15 and 22 of each treatment cycle.
