Current hemophilia treatment involves frequent intravenous infusions of clotting factors, which is associated with variable hemostatic protection, a high burden, and risk the development inhibitory alloantibodies. Fitusiran, an investigational RNA interference (RNAi) therapy that targets antithrombin (encoded by SERPINC1), in to address these other limitations.

Erythropoiesis-stimulating agents are first choice for treating anemia in low-risk MDS. This double-blind, placebo-controlled study assessed the efficacy and safety of epoetin-α IPSS low- or intermediate-1 risk (i.e., low-risk) MDS patients with Hb ≤ 10.0 g/dL, no moderate RBC transfusion dependence (≤4 units/8 weeks). Patients were randomized, 2:1, to receive 450 IU/kg/week placebo 24 weeks, followed by treatment extension responders. The primary endpoint was erythroid response (ER) through...

We compared the safety and efficacy of siltuximab (S), an anti‐interleukin‐6 chimeric monoclonal antibody, plus bortezomib (B) with placebo (plc) + B in patients relapsed/refractory multiple myeloma a randomized phase 2 study. Siltuximab was given by 6 mg/kg IV every weeks. On progression, discontinued high‐dose dexamethasone could be added to S/plc. Response progression‐free survival (PFS) were analyzed pre‐dexamethasone European Group for Blood Marrow Transplantation (EBMT) criteria. For...

Summary The efficacy of bendamustine versus chlorambucil in a phase III trial previously untreated patients with B inet stage B/C chronic lymphocytic leukaemia ( CLL ) was re‐evaluated after median observation time 54 months M ay 2010. Overall survival OS analysed for the first time. At follow‐up, investigator‐assessed complete response CR rate (21·0% vs 10·8%), progression‐free (21·2 8·8 months; P &lt; 0·0001; hazard ratio 2·83) and to next treatment (31·7 10·1 0·0001) were improved over...

This phase 3 study evaluated the efficacy and safety of new hypomethylating agent guadecitabine (n = 408) vs a preselected treatment choice (TC; n 407) azacitidine, decitabine, or low-dose cytarabine in patients with acute myeloid leukemia unfit to receive intensive induction chemotherapy. Half (50%) had poor Eastern Cooperative Oncology Group Performance Status (2-3). The coprimary end points were complete remission (19% 17% for TC, respectively [stratified P .48]) overall survival (median...
