BACKGROUND Ruxolitinib, a Janus kinase (JAK) 1 and 2 inhibitor, was shown to have a clinical benefit in patients with polycythemia vera in a phase 2 study. We conducted a phase 3 open-label study to evaluate the efficacy and safety of ruxolitinib versus standard therapy in patients with polycythemia vera who had an inadequate response to or had unacceptable side effects from hydroxyurea. METHODS We randomly assigned phlebotomy-dependent patients with splenomegaly, in a 1:1 ratio, to receive ruxolitinib (110 patients) or standard therapy (112 patients). The primary end point was both hematocrit control through week 32 and at least a 35% reduction in spleen volume at week 32, as assessed by means of imaging. RESULTS The primary end point was achieved in 21% of the patients in the ruxolitinib group versus 1% of those in the standard-therapy group (P<0.001). Hematocrit control was achieved in 60% of patients receiving ruxolitinib and 20% of those receiving standard therapy; 38% and 1% of patients in the two groups, respectively, had at least a 35% reduction in spleen volume. A complete hematologic remission was achieved in 24% of patients in the ruxolitinib group and 9% of those in the standard-therapy group (P = 0.003); 49% versus 5% had at least a 50% reduction in the total symptom score at week 32. In the ruxolitinib group, grade 3 or 4 anemia occurred in 2% of patients, and grade 3 or 4 thrombocytopenia occurred in 5%; the corresponding percentages in the standard-therapy group were 0% and 4%. Herpes zoster infection was reported in 6% of patients in the ruxolitinib group and 0% of those in the standard- therapy group (grade 1 or 2 in all cases). Thromboembolic events occurred in one patient receiving ruxolitinib and in six patients receiving standard therapy. CONCLUSIONS In patients who had an inadequate response to or had unacceptable side effects from hydroxyurea, ruxolitinib was superior to standard therapy in controlling the hematocrit, reducing the spleen volume, and improving symptoms associated with polycythemia vera.

Among patients with previously untreated follicular lymphoma, efficacy results were similar with rituximab plus lenalidomide and rituximab plus chemotherapy (with both regimens followed by rituximab maintenance therapy). The safety profile differed in the two groups. (Funded by Celgene; RELEVANCE ClinicalTrials.gov numbers, NCT01476787 and NCT01650701 , and EudraCT number, 2011-002792-42 .).

Summary:In a 10-year consecutive series of 263 allogeneic bone marrow transplant recipients, we identified five cases (1.9%) of invasive mucormycosis. Only one infection occurred within the first 100 days after transplantation, while the remainder complicated the late post-transplant course (median day of diagnosis: 343). Sites of infection were considered 'non-classical' and included pulmonary, cutaneous and gastric involvement. No case of fungal dissemination was observed. Mucormycosis was the primary cause of death in three of the five patients. Corticosteroid-treated graft-versus-host disease, either acute or chronic, or severe neutropenia were present in all cases. However, compared with a matched control population, the most striking finding was the demonstration of severe iron overload in each of the mucormycosis patients. The mean level of serum ferritin, transferrin saturation and number of transfused units of red cells (2029 g/l, 92% and 52 units, respectively) in the study group is significantly higher compared with the control group (P Ͻ 0.05). The difference with other risk groups for mucormycosis, including deferoxamine-treated dialysis patients and acidotic diabetics, was analyzed in view of the possible pathogenic role of iron. Although these infections are often fatal, limited disease may have a better prognosis if diagnosed early and treated aggressively.

To the best of our knowledge, this is the first long-term analysis confirming that GnRHa is not efficient in preventing chemotherapy-induced POF in young patients with lymphoma and did not influence future pregnancy rate. These results reopen the debate about the drug's benefit in that it should not be recommended as standard for fertility preservation in patients with lymphoma.
