Long-term safety and efficacy of fitusiran prophylaxis, and perioperative management in people with hemophilia A or B.

Fitusiran is an investigational small interfering RNA therapeutic that targets antithrombin (AT) to rebalance hemostasis in people with hemophilia. Here we present the results of the completed Phase 2 open-label extension study, which evaluated the long-term safety and efficacy of fitusiran in participants with moderate or severe hemophilia A or B, with or without inhibitors. Male participants who had completed the Phase 1 study (NCT02035605) were enrolled.

A phase 1 dose escalation study of the pyruvate kinase activator mitapivat (AG-348) in sickle cell disease.

Polymerization of deoxygenated hemoglobin S underlies the pathophysiology of sickle cell disease (SCD). In activating red blood cell pyruvate kinase and glycolysis, mitapivat (AG-348) increases adenosine triphosphate (ATP) levels and decreases the 2,3-diphosphoglycerate (2,3-DPG) concentration, an upstream precursor in glycolysis. Both changes have therapeutic potential for patients with SCD.

Global Variation in Opioid Use in Prostate Cancer Trials.

Importance: Regional variation in opioid use may be attenuated when pharmaceutical-sponsored trials include care that is often standardized by protocols. Understanding such variation is important for global trials that sometimes include time to opioid use as an end point.

Objective: To identify whether regional and country-level variation in opioid use exists among prostate cancer clinical trials across the world.

Predictors of recurrent venous thromboembolism and bleeding on anticoagulation.

The impact of venous thromboembolism (VTE) in the cancer population remains substantial despite significant advances in detecting and treating thrombotic events. While there is extensive literature regarding predictors of first VTE event in cancer patients as well as a validated predictive score, less data exist regarding recurrent VTE in cancer cohorts and associated predictive variables. A similar paucity of data in regard to bleeding events in cancer patients receiving anticoagulation has been observed.

Prevalence and clinical significance of incidental and clinically suspected venous thromboembolism in lung cancer patients.

Background: It is unclear what proportion of VTE events in lung cancer patients are incidentally discovered and whether incidental events affect mortality.

Patients And Methods: We conducted a retrospective cohort study of lung cancer patients seen at the University of Rochester between January 1, 2006 and December 31, 2008 with the goal of quantifying and characterizing VTE events. Multiple clinical variables and mortality outcomes were compared using Kaplan-Meier survival analysis and multivariate Cox proportional hazards.

Symptomatic and incidental thromboembolism are both associated with mortality in pancreatic cancer.

Pancreatic cancer is known to be associated with VTE, but contemporary rates of incidental and symptomatic VTE events and their association with mortality are incompletely understood. We conducted a retrospective cohort study of consecutive pancreatic adenocarcinoma patients at the University of Rochester from 2006-2009. Data were analysed using a Cox model with time-dependent covariates.

The role of thromboprophylaxis in cancer patients: emerging data.

Purpose Of Review: Venous thromboembolism (VTE) is a frequent cause of morbidity and mortality in cancer patients. A significant proportion of cancer-associated VTE occurs in the ambulatory setting and is associated with poorer outcomes and reduced survival. Risk for VTE is influenced by patient, cancer and treatment-specific factors.
