Regimen deemed ‘safe and feasible’ in MM

At 90 days post-ASCT, 2 patients (13%) had a stringent CR, and 4 (27%) had a CR. Six patients (40%) had a VGPR, and 2 (13%) had a PR. One patient (7%) had progressed.

“In this very high-risk PR/VGPR population, stem cell transplant with elotuzumab and PBMC infusion resulted in a CR rate of 40%—with 13% of patients achieving stringent CR—by day 90,” Dr Osman noted. “And maintenance elotuzumab plus lenalidomide promoted further conversion to 33% stringent CR by 1 year.”

At 1 year, 5 patients (33%) had a stringent CR, and 1 (7%) had a CR. Six patients (40%) had a VGPR, and 1 (7%) had a PR. Two patients (13%) had progressed.

So the 1-year progression-free survival rate was 86% (13/15).

“In conclusion, we see that elotuzumab and PBMC administration with standard autologous stem cell transplant and lenalidomide maintenance for consolidation therapy in multiple myeloma is certainly both safe and feasible,” Dr Osman said. “We’re planning a phase 2 study.”
