Active clinical trials for "Antiphospholipid Syndrome"

Antiphospholipid antibody syndrome (APS) is characterized by the presence of antiphospholipid antibodies, which are proteins in the blood that interfere with the body's ability to perform normal blood clotting. Clinical problems associated with antiphospholipid antibodies include an increased risk for the formation of blood clots in the lungs or deep veins of the legs, stroke, heart attack, and recurrent miscarriages. It is possible that some people with APS have a genetic predisposition for developing the syndrome. This study will use a genetic strategy to identify potential inherited risk factors for the development of APS by recruiting people with APS who have family members also affected by the syndrome or by another autoimmune disorder, such as lupus or rheumatoid arthritis.

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thrombosis and pregnancy morbidity in patients with persistently positive antiphospholipid antibodies (aPLs). However, large-scale research on general population with persistent aPLs has been lacking. This project proposes to establish the first multicenter cohort of patients with persistently positive aPLs in China and conduct a comprehensive clinical phenotyping study. Based on traditional phenotypes of thrombotic and pregnancy events, the focus will be on extra-standard clinical phenotypes and prospective assessment of event risk and prognosis in aPL-positive population. A prospective analysis of extra-standard antibodies will also be conducted to recommend detection criteria for extra-standard antibody application in China and to assess their clinical significance.

To constitute a registry of antiphospholipid antibodies positive-patients

Longitudinal prospective multicenter Armenian registry of systemic autoimmune, autoinflammatory diseases with constitution of bio-banking.

The purpose of this study is to gather information about causes and treatment of Antiphospholipid Syndrome.

The primary purpose of this study was to evaluate the safety and tolerability of intravenous (IV) ALXN1007 in persistently antiphospholipid (aPL)-positive patients with at least 1 of the following non-criteria manifestations of APS: aPL-nephropathy, skin ulcers and/or thrombocytopenia.

The APPLE pilot trial is a feasibility study that is a multicentre, open-label, randomized controlled trial. Pregnant women with antiphospholipid syndrome (APS) and a history of late (≥10 weeks gestation) or recurrent early (2 <10 weeks) pregnancy loss will be recruited. Eligible and consenting subjects will be assigned to one of two study arms: open-label low-molecular-weight heparin (LMWH) prophylaxis until 37 weeks gestation AND low-dose aspirin (ASA) daily until delivery, or open-label low-dose aspirin daily from randomization until delivery.

To compare the livebirth rate of women with recurrent pregnancy loss and autoantibodies randomized to either low molecular weight heparin plus aspirin versus aspirin alone.

The purpose of this study is to explore if certain commensals within the gut microbiota (the collection of all microbes that live inside the gut) correlate with autoantibodies in the autoimmune clotting disorder called antiphospholipid syndrome. The study hypothesis is that particular commensals induce the autoantibodies (immune molecules that bind to self structures) and thus correlate with the level of immune cells and antibodies that are self-reactive. Participants are patients with antiphospholipid syndrome and individuals who have tested positive on a prior blood test for anti-beta2-glycoprotein I antibodies or those that have tested negative for antiphospholipid antibodies in their blood, but had a clotting event or a health problem that puts them at risk to form blood clots.

Primary Study Objective(s) The primary objective is to demonstrate the non-inferiority of Rivaroxaban 20 mg (or 15mgqd in case of moderate renal insufficiency) versus warfarin (INR 2.0-3.0) with respect to the occurrence of the cumulative end point of incident acute thrombosis (arterial or venous) confirmed by appropriate imaging studies, major bleedings, and death in triple aPL-positive APS patients. Study Design A multicentre, interventional, prospective, parallel, randomised, controlled, open-label, Rivaroxaban 20 mg qd (or 15mg qd in patients with moderate renal insufficiency) vs warfarin (INR target 2.5), non-inferiority study, in 535 triple aPL-positive APS patients in approximately 40 Internal Medicine and Thrombosis centres. Each local Institutional Review Board will approve the study. Study Population Patients of both sexes, of age 18-75, affected by anti-phospholipid syndrome, with a high probability of recurrences as defined by triple aPL-positivity, are eligible for this study. Primary Outcome variables The primary cumulative outcome measure will be incident acute thrombosis (arterial or venous) confirmed by appropriate imaging studies, major bleeding, or death. Secondary Outcome variables Separate evaluation of arterial and venous thrombosis and all-cause death. 04.27.2015: An amendment has been made. Enrollment permitted till 75 years of age.
