The factor XI/XIa antibody abelacimab combined with enoxaparin inhibits filter clotting in hemodialysis circuits ex vivo.

Drugs targeting factor XI may offer an alternative to heparin for preventing blood clotting in extracorporeal circulation. We investigated the effects of abelacimab, a novel monoclonal antibody targeting factor XI. We collected whole blood samples into two bags (each 240 ml, control group: enoxaparin 1.

Treatment of Cancer-Associated Thrombosis: Recent Advances, Unmet Needs, and Future Direction.

Cancer-associated thrombosis, with the incidence rising over the years, is associated with significant morbidity and mortality in patients with cancer. Recent advances in the treatment of cancer-associated venous thromboembolism (VTE) include the introduction of direct oral anticoagulants (DOACs), which provide a more convenient and effective option than low-molecular-weight heparin (LMWH). Nonetheless, important unmet needs remain including an increased risk of bleeding in certain patient subgroups such as those with gastroesophageal cancer, concerns about drug-drug interactions, and management of patients with severe renal impairment.

Acceptability of multiple coated mini-tablets in comparison to syrup in infants and toddlers: a randomised controlled study.

Objectives: Drug treatment of children is often limited to liquid formulations or manipulation of adult solid oral dosage forms because of the lack of age-appropriate formulations, concerns around particle aspiration and paediatric acceptability. Recent research revealed that the administration of mini-tablets has substantial advantages in improving dose accuracy and avoiding issues related to drug stability, storage conditions, potentially toxic excipients and taste masking (especially effective when the mini-tablets are coated). Most trials were performed with single and multiple mini-tablets.

MAA868, a novel FXI antibody with a unique binding mode, shows durable effects on markers of anticoagulation in humans.

A large unmet medical need exists for safer antithrombotic drugs because all currently approved anticoagulant agents interfere with hemostasis, leading to an increased risk of bleeding. Genetic and pharmacologic evidence in humans and animals suggests that reducing factor XI (FXI) levels has the potential to effectively prevent and treat thrombosis with a minimal risk of bleeding. We generated a fully human antibody (MAA868) that binds the catalytic domain of both FXI (zymogen) and activated FXI.

The effect of sacubitril/valsartan compared to olmesartan on cardiovascular remodelling in subjects with essential hypertension: the results of a randomized, double-blind, active-controlled study.

Aims: Progressive aortic stiffening eventually leads to left ventricular (LV) hypertrophy and heart failure if left untreated. Anti-hypertensive agents have been shown to reverse this to some extent. The effects of sacubitril/valsartan (LCZ696), a dual-action angiotensin receptor blocker (ARB), and neprilysin inhibitor, on arterial stiffness and LV remodelling have not been investigated.

Sacubitril/Valsartan (LCZ696) in Heart Failure.

It has been known since the 1990s that long-term morbidity and mortality is improved in patients with heart failure with reduced ejection fraction (HFrEF) by treatments that target the renin-angiotensin-aldosterone system (RAAS). It has also long been thought that enhancement of the activity of natriuretic peptides (NPs) could potentially benefit patients with HFrEF, but multiple attempts to realize this benefit had failed over the years - until 2014, when a large, phase III, randomized, controlled clinical trial (PARADIGM-HF) was completed comparing sacubitril/valsartan with enalapril, a well-established treatment for HFrEF. Sacubitril/valsartan (formerly known as LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor (ARNI) that simultaneously suppresses RAAS activation through blockade of angiotensin II type 1 receptors and enhances vasoactive peptides including NPs through inhibition of neprilysin, the enzyme responsible for their degradation.

Dabigatran versus warfarin in patients with mechanical heart valves.

Background: Dabigatran is an oral direct thrombin inhibitor that has been shown to be an effective alternative to warfarin in patients with atrial fibrillation. We evaluated the use of dabigatran in patients with mechanical heart valves.

Methods: In this phase 2 dose-validation study, we studied two populations of patients: those who had undergone aortic- or mitral-valve replacement within the past 7 days and those who had undergone such replacement at least 3 months earlier.

Dabigatran vs. placebo in patients with acute coronary syndromes on dual antiplatelet therapy: a randomized, double-blind, phase II trial.

Aim: After an acute coronary syndrome, patients remain at risk of recurrent ischaemic events, despite contemporary treatment, including aspirin and clopidogrel. We evaluated the safety and indicators of efficacy of the novel oral direct thrombin inhibitor dabigatran.

Methods And Results: In this double-blind, placebo-controlled, dose-escalation trial, 1861 patients (99.

Ambulatory blood pressure-lowering effects of valsartan and enalapril after a missed dose in previously untreated patients with hypertension: a prospective, randomized, open-label, blinded end-point trial.

Background: Approximately 3 days a month, some 15% to 20% of patients with hypertension do not recall having taken their antihypertensive medication. Individuals with this frequency of missed doses may be at increased risk for a cardiovascular event and may have a poorer long-term prognosis.

Objective: This study used ambulatory blood pressure monitoring (ABPM) to compare the blood pressure (BP)-lowering effects of valsartan and enalapril over the 24 hours after missing 1 dose in previously untreated patients with mild to moderate essential hypertension.

Antihypertensive efficacy and tolerability of two fixed-dose combinations of valsartan and hydrochlorothiazide compared with valsartan monotherapy in patients with stage 2 or 3 systolic hypertension: an 8-week, randomized, double-blind, parallel-group trial.

Background: Combination therapy with at least 2 antihypertensive agents is usually needed to achieve appropriate blood pressure (BP) control in patients with isolated or predominant systolic hypertension. A currently recommended combination is a diuretic added to an angiotensin-receptor blocker.

Objective: This was a study of the effects on sitting systolic BP (SBP)of 2 combinations of valsartan and hydrochlorothiazide (HCTZ) compared with valsartan monotherapy in patients with stage 2 or 3 systolic hypertension (SBP > or =160 mm Hg and < or =200 mm Hg) with or without other cardiovascular risk factors.

Efficacy and tolerability of combination therapy with valsartan plus hydrochlorothiazide compared with amlodipine monotherapy in hypertensive patients with other cardiovascular risk factors: the VAST study.

Background: Recent antihypertensive treatment guidelines recommend greater use of combination therapies.

Objectives: The primary objective of this study was to determine whether combination therapy with valsartan 160 mg plus hydrochlorothiazide (HCTZ) 25 mg OD would be more effective than monotherapy with amlodipine 10 mg OD in reducing systolic blood pressure (SBP) in patients with moderate (stage II) hypertension and > or =1 other cardiovascular risk factor or concomitant condition. A secondary objective was to assess the effects of the study treatments on circulating markers of endothelial dysfunction and vascular inflammation.

24-hour ambulatory blood-pressure effects of valsartan and hydrochlorothiazide combinations compared with amlodipine in hypertensive patients at increased cardiovascular risk: a VAST sub-study.

Background: There is a lack of data on the effects of angiotensin-receptor blocker and diuretic combinations on ambulatory blood pressure (ABP) in hypertensive patients with additional cardiovascular risk factors.

Methods: In a randomized, double-blind trial, the effects on 24-h ABP of the combination valsartan 160 mg od and hydrochlorothiazide 25 or 12.5 mg during 24 weeks of therapy were compared with the effects of amlodipine 10 mg monotherapy (group A10) in 474 stage-II hypertensive patients with additional cardiovascular risk factors.
