BACKGROUND: The outcome of older patients with B-cell acute lymphocytic leukaemia is inferior to that in younger patients due to the adverse disease biology and their inability to tolerate intensive therapy. We aimed to study the long-term outcomes of inotuzumab ozogamicin with or without blinatumomab in combination with low-intensity chemotherapy in these patients. METHODS: For this open-label phase 2 trial, patients aged 60 years or older with newly diagnosed, Philadelphia-chromosome negative, B-cell acute lymphocytic leukaemia, and an ECOG performance status of 3 or lower were eligible...

BACKGROUND: Acute myeloid leukaemia with mutated NPM1 is associated with high CD33 expression and intermediate-risk cytogenetics. The aim of this study was to evaluate intensive chemotherapy with or without the anti-CD33 antibody-drug conjugate gemtuzumab ozogamicin in participants with newly diagnosed, NPM1-mutated acute myeloid leukaemia. METHODS: This open-label, phase 3 trial was conducted at 56 hospitals in Germany and Austria. Eligible participants were 18 years or older and had newly diagnosed NPM1-mutated acute myeloid leukaemia and an Eastern Cooperative Oncology Group performance status of 0-2...

BACKGROUND: T-cell acute lymphoblastic leukaemia has distinct biological characteristics and a poorer prognosis than B-cell precursor acute lymphoblastic leukaemia. This trial aimed to reduce the rate of radiation and haematopoietic stem-cell transplantation (HSCT) while improving outcomes by adding nelarabine, intensified L-asparaginase, and protracted intrathecal therapy in the Berlin-Frankfurt-Münster (BFM)-type treatment. METHODS: In this nationwide, multicenter, phase 2 trial, we enrolled patients with newly diagnosed T-cell acute lymphoblastic leukaemia (age <25 years at diagnosis) conducted by Japan Children's Cancer Group and Japan Adult Leukemia Study Group...

BACKGROUND: Survival of children and adolescents with high-risk, mature B-cell non-Hodgkin lymphoma is improved by the addition of rituximab to chemotherapy. The effect of rituximab on immune reconstitution after therapy has not been well described. Herein, we evaluate the immune effects of the addition of rituximab to intensive chemotherapy, a prespecified secondary aim of the Inter-B-NHL Ritux 2010 trial. METHODS: The Inter-B-NHL Ritux 2010 trial was an international, open-label, randomised, phase 3 trial in children (age 6 months to 18 years) with high-risk, mature B-cell non-Hodgkin lymphoma, comparing chemotherapy alone or chemotherapy with rituximab...

Sickle cell disease is the most frequent inherited disorder in sub-Saharan Africa and in many high-income countries (HICs). Transfusion is a key element of treatment, but it results in high rates of alloimmunisation against red blood cell antigens and post-transfusion haemolysis, which can be life-threatening in severe cases. The prevention of alloimmunisation is, therefore, an important issue in both HICs and in low-income countries (LICs). In HICs, the main reason for high alloimmunisation rates is blood group disparity between blood donors, who are mostly of European descent, and the patients, who are mostly of African descent...

BACKGROUND: Spleen tyrosine kinase (Syk) inhibitor is a treatment option for primary immune thrombocytopenia. We aimed to evaluate the safety, tolerability, pharmacokinetics, preliminary activity, and recommended phase 2 dose of sovleplenib in patients with primary immune thrombocytopenia. METHODS: This randomised, double-blind, placebo-controlled, phase 1b/2 study was conducted at nine hospitals in China. Eligible patients were aged 18-75 years, had an ECOG performance score of 0-1, had primary immune thrombocytopenia for more than 6 months, and did not respond or relapsed after previous first-line treatment or had poor response or postoperative relapse after a splenectomy...

BACKGROUND: Lymphomatoid granulomatosis is a rare Epstein-Barr virus-associated B-cell lymphoproliferative disorder with a median overall survival of less than 2 years. In this study, we hypothesised that low-grade lymphomatoid granulomatosis is immune-dependent and high-grade lymphomatoid granulomatosis is immune-independent. On the basis of this hypothesis, we investigated the activity and safety of new treatment with immunotherapy in patients with low-grade disease and standard chemotherapy in patients with high-grade disease...

Multidrug chemotherapy has historically been the cornerstone of therapy for both children and adults with acute lymphocytic leukaemia. However, in the past decade, several novel immunotherapies have proven to be highly effective in the treatment of acute lymphocytic leukaemia, including the anti-CD22 antibody-drug conjugate inotuzumab ozogamicin, the CD3 × CD19 bispecific antibody blinatumomab, and two CD19-directed chimeric antigen receptor T-cell products. These agents are all approved in the USA as monotherapy for relapsed or refractory B-cell acute lymphocytic leukaemia...

BACKGROUND: Fitusiran, a subcutaneous investigational siRNA therapeutic, targets antithrombin with the goal of rebalancing haemostasis in people with haemophilia A or haemophilia B, regardless of inhibitor status. We aimed to evaluate the efficacy and safety of fitusiran prophylaxis in people with severe haemophilia without inhibitors. METHODS: This multicentre, open-label, randomised phase 3 study was conducted at 45 sites in 17 countries. Male participants aged at least 12 years with severe haemophilia A or B without inhibitors, who had previously been treated on-demand with clotting factor concentrates, were randomly assigned in a 2:1 ratio to receive 80 mg subcutaneous fitusiran prophylaxis once per month or to continue on-demand clotting factor concentrates for a total of 9 months...

BACKGROUND: Sinusoidal obstruction syndrome, also known as veno-occlusive disease, is a potentially life-threatening complication of haematopoietic stem-cell transplantation (HSCT). We aimed to compare defibrotide prophylaxis plus best supportive care versus best supportive care alone for sinusoidal obstruction syndrome prevention after HSCT. METHODS: This open-label, randomised, multicentre, phase 3 trial was done in 104 centres in 14 countries. Patients who were at least 1 month old, were scheduled to receive allogeneic HSCT (adult [aged >16 years] or paediatric [aged >1 month to ≤16 years] patients) or autologous HSCT (paediatric patients only), and were at high risk or very high risk of developing sinusoidal obstruction syndrome were eligible for inclusion...
