guaranteed for patients with MM. “A challenge in sequencing myeloma treatment is the diminishing effectiveness of each successive line of treatment, with a shorter period of disease response with [subsequent] therapy,” Drs. Yee and Raje pointed out. “Furthermore, patients who are refractory to newer agents such as lenalidomide and bortezomib have histori- cally had a poor prognosis.” Dr. Rajkumar agreed that sequenc- ing in these patients can be difficult and outlined a preferred sequence for relapse in an editorial in the New England Journal of Medicine: 6 • If patients are deemed too frail for these regimens, then ixazomib or elotuzumab could be used in place of daratumumab or carfilzomib (IRD and ERD, respectively). • In first relapse among patients who are not refractory to lenalidomide, use a combination of daratumumab, le- nalidomide, and low-dose dexametha- sone or carfilzomib, lenalidomide, and dexamethasone. • For those who are refractory to le- nalidomide but not frail, try a combi- nation of doxorubicin, vincristine, and dexamethasone or bortezomib, cyclo- phosphamide, and dexamethasone. S:6.75” • For frail patients, pembrolizumab and dexamethasone, with or without ixazomib, is another option. Recent approvals of monoclonal antibod- ies, including elotuzumab and daratu- mumab, have broadened the treatment landscape for all patients with myeloma. The toxicities associated with these agents tend to occur early in treatment. In pivotal trials, infusion reactions were the most BOSULIF offers proven efficacy for patients with resistance or intolerance to prior therapy 2 In 2nd-line treatment, after imatinib (n=266 evaluable) a 34 % of patients 53 % of patients achieved MCyR at 6 months achieved MCyR with a minimum follow-up of 23 months (95% CI: 28.2, 39.9) Median duration of MCyR was not reached at the time of analysis 53% of patients with MCyR maintained MCyR for at least 18 months (with a minimum follow-up of 23 months) In 3rd-line treatment, after imatinib followed by nilotinib and/or dasatinib therapy (n=108 evaluable) • 27% of patients achieved MCyR by 6 months (95% CI: 18.8, 36.2) • 32% of patients achieved MCyR with a minimum follow-up of 13 months • Median duration of MCyR was not reached at the time of analysis — 51% of patients with MCyR maintained MCyR for at least 9 months (with a minimum follow-up of 13 months) BOSULIF has a distinct safety and
