In this double-blind, placebo-controlled study, 363 patients with untreated multiple myeloma were randomized to receive either melphalan-prednisone and thalidomide (MPT) or melphalan-prednisone and placebo (MP). The dose of melphalan was 0.25 mg/kg and prednisone was 100 mg given daily for 4 days every 6 weeks until plateau phase. The dose of thalidomide/ placebo was escalated to 400 mg daily until plateau phase and thereafter reduced to 200 mg daily until progression. A total of 357 patients were analyzed. Partial response was 34% and 33%, and very good partial response or better was 23% and 7% in the MPT and MP arms, respectively (P < .001). There was no significant difference in progression-free or overall survival, with median survival being 29 months in the MPT arm and 32 months in the MP arm. Most quality of life outcomes improved equally in both arms, apart from constipation, which was markedly increased in the MPT arm. Constipation, neuropathy, nonneuropathy neurologic toxicity, and skin reactions were significantly more frequent in the MPT arm. The number of thromboembolic events was equal in the 2 treatment arms. In conclusion, MPT had a significant antimyeloma effect, but this did not translate into improved survival. This trial was

Background Maintenance therapy following autologous stem cell transplantation can delay disease progression and prolong survival in multiple myeloma (MM). Ixazomib is ideally suited for maintenance therapy given its efficacy, convenient once-weekly oral dosing, and low toxicity profile. Methods The phase 3, double-blind, placebo-controlled, TOURMALINE-MM3 study randomised 656 patients with newly diagnosed MM from 227 clinical/hospital sites in 30 countries in Europe, the Middle East, Africa,

We retrospectively studied 232 patients with cold agglutinin disease (CAD) at 24 centers in five countries. In Norway and a northern region of Italy, the study was close to being population-based. For the first time, we demonstrate 4-fold differences between cold and warmer climates regarding prevalence (20 versus 5 cases/million) and incidence (1.9 versus 0.48 cases/million/year). Mean baseline hemoglobin level was 9.3 g/dL, but 27% had hemoglobin &lt; 8 g/dL. Identification of typical features of 'CAD-associated lymphoproliferative disorder' in the bone marrow was greatly increased by centralized biopsy assessment. CAD seems to be associated with a slightly increased risk of venous thrombosis. This work included a follow-up study of therapies, focusing on the long-term outcomes of the rituximab plus bendamustine and rituximab plus fludarabine regimens. Rituximab plus bendamustine therapy resulted in responses in 35 (78%) of 45 patients; 24 (53%) achieved complete response. Interestingly, these rates were still higher than observed in the original (2017) prospective trial, and we also found a shift towards deeper responses with time. This is explained by the prolonged time to response seen in many patients, probably related to long-lived plasma cells. In patients responding to rituximab-bendamustine, median response duration was not reached after 88 months, and estimated 5-year sustained remission was 77%. The regimen appeared safe regarding late-occurring malignancies. Rituximab plus fludarabine therapy seems to carry a higher risk of long-term adverse effects.

Key Points Bortezomib consolidation after ASCT improves PFS in myeloma. Improvement of response is seen with bortezomib consolidation after ASCT in myeloma.

Key Points Bendamustine-rituximab therapy results in high overall and CR rates with sustained remissions in CAD. Bendamustine plus rituximab may be considered in first line for most patients with CAD requiring therapy.
