Multicenter Study Clinical Trial
Ruxolitinib combined with etanercept induce a rapid response to corticosteroid-refractory severe acute graft vs host disease after allogeneic stem cell transplantation: Results of a multi-center prospective study.
About half of patients with severe acute graft vs host disease (aGVHD) show resistance to treatment with first-line steroids. We enrolled 64 patients with grades III-IV SR-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-SCT), to assess the efficacy and safety of the combination therapy of ruxolitinib and etanercept. The overall response rate was 87.5% (95% CI, 79.7%-95.3%) at day 28 of the combination treatment, from which 73.4% reached complete response (CR). ⋯ The 2-year incidence of non-relapse mortality and relapse of the underlying malignancy was 26.7% and 15.7%, respectively. Combined treatment with ruxolitinib and etanercept was very effective and relatively safe for severe aGVHD patients, while the various infection complications deserve more attention. This study was registered at the Chinese Clinical Trial Registry (ChiCTR1900024408).

Daratumumab demonstrated activity in the treatment of AL amyloidosis in two recently concluded phase II clinical trials in relapsed and refractory patients. Its role in upfront therapy is under evaluation in a phase III study. In this report we evaluated the safety and efficacy of 28-day cycles of daratumumab (single agent or combined with bortezomib or lenalidomide) in 72 previously treated patients with multiple myeloma and AL amyloidosis. ⋯ Cardiac response was observed in 11 of 37 evaluable patients (29%) and renal response in 23 of 38 patients (60%). Daratumumab is highly effective in heavily pretreated patients with relapsed/refractory AL amyloidosis and high bone marrow plasma cell burden. Renal responses, which are usually rare in this setting, were frequently observed.
