Effect of Alkali Therapy on Vascular and Graft Function in Kidney Transplant Recipients

Metabolic AcidosisKidney Transplant; Complications1 more

Lower serum bicarbonate levels, even within the normal laboratory range, in kidney transplant recipients (KTRs) are associated with an increased risk of graft loss, cardiovascular events and mortality. Because acid retention is common in KTRs, it is plausible that alkali therapy in KTRs may also result in improved vascular and graft function. The investigators will perform a randomized, double-blinded, placebo-controlled, 12 month study in 120 KTRs to examine the effect of sodium bicarbonate therapy on surrogate markers of CVD and graft function. The overall hypothesis is that treatment with bicarbonate will improve indicators of vascular and graft function in KTRs by decreasing complement activation.

AERIAL Trial: Antiplatelet Therapy in Heart Transplantation

Cardiac Allograft VasculopathyHeart Transplant

Cardiac allograft vasculopathy is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. The research team is investigating whether early antiplatelet therapy post heart transplant can prevent the development of CAV. This study will determine the feasibility of a large multicenter randomized placebo-controlled trial to answer this question.

Efficacy and Safety Of Alirocumab to Prevent Early Cardiac Allograft Vasculopathy in Recent Heart...

Cardiac Allograft Vasculopathy

Cardiac allograft vasculopathy (CAV) represents the leading cause of late morbidity and mortality in heart transplant recipients as the second most frequent cause of all deaths at 3 years. In distinction from general coronary atherosclerosis, CAV affects diffusely the entire coronary vasculature with marked intimal proliferation and concentric vascular thickening and fibrosis. It was demonstrated that most of the intimal thickening due to CAV occurs during the first year after transplantation. Furthermore, the severity of the CAV appears to correlate with lipid abnormalities and elevated low-density lipoprotein cholesterol (LDL-C) is very common after transplantation with nadir of LDL levels occurring at 6 months. Because of drug-drug interactions, heart transplant recipients cannot be treated with adequate doses of statins to achieve desirable reduction of LDL-C levels (reduction ˂ 60% of LDL-C). The use of alternative lipid-lowering drugs including bile acid sequestrates, fibrates, nicotinic acid or ezetimibe is not recommended in post-transplant scenario. Inhibition of proprotein convertase subtilisin/kexin type 9 (PCSK9) increase availability has emerged as a novel drug tool for LDL-C lowering, capable to lower LDL-C by more than 60% even in statin-treated patients with very good safety profile. Although heart transplant recipients fulfill approved indication and standard clinical guidelines of a PCSK9 inhibitor, alirocumab, there are no available data on use of PCSK9 inhibitor in post-transplant situation. The purpose of the ACAV study is to clarify efficacy and safety of alirocumab compared to placebo administered during the first year after transplantation in heart transplant recipients in addition to background atorvastatin therapy. Except lipid profile, optical coherence tomography (OCT) will be performed as the objective efficacy endpoint to examine thickness and lumen of coronary vessels. It is expected that inhibition of PCSK9 in heart transplant recipient will dramatically improve post-transplant lipoprotein levels and perhaps slow down development of CAV in the most critical period of the first year after transplantation.

Hyperbaric Oxygen Therapy for Prodromal Alzheimer´s Disease With Cerebrovascular Disease

Prodromal Alzheimer's DiseaseCerebral Vascular Disorder2 more

Alzheimer´s disease is a devastating illness that effects the patients as well as their family members. Its prevalence increases exponentially and the burden on the healthcare system is enormous. AD neuropathology begins 15-20 years before the occurrence of cognitive symptoms, which ranges from preclinical stage to mild cognitive impairment (MCI) to dementia. Prodromal AD is an early stage of the disease which is characterized by positive biomarkers and MCI. To this day, there is no medication that can cure or halt the progression of the disease and most studies focus on finding reversible risk factors and changing their influence. Several aetiologies have been proposed, like the deposition of amyloid and tau proteins, neuroinflammation and cerebral ischemia due to cerebrovascular factors. The Amyloid deposition, which serves as the biological marker of AD, was originally thought to be the main cause of the disease, however, recent data suggests that it is not the cause and that it might actually has a protective role. On the other hand, it is known today that vascular changes with related tissue ischemia and neuroinflammation have a crucial role in the development of AD in many patients. These pathologies, ischemia & neuroinflammation, can be improved by the use of hyperbaric oxygen therapy (HBOT). The goal of this study is to explore the potential beneficial effect of HBOT on prodromal AD.

Dual Anti-Platelet Therapy in Patients With Coronary Multi-Vessel Disease (DAPT-MVD)

Coronary Artery DiseaseMyocardial Ischemia8 more

This study is a prospective, multicenter, parallel, open-label, randomized, controlled, superiority trial. It is planned to recruit 8,250 patients with multi-vessel disease(MVD), and the patients will be followed-up for 12 months after being implanted with a drug-eluting stent (DES) at one of 100 different centers. All patients will be randomly divided into the treatment group and control group on a 1:1 basis, based on a complete randomization.

Ravulizumab in Thrombotic Microangiopathy After Hematopoietic Stem Cell Transplant

Thrombotic Microangiopathy

This study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of ravulizumab in adult and adolescent participants with hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA). In Stage 1, an open-label, single-arm period, the dosing regimen will be confirmed. In Stage 2, participants will be randomized to receive either blinded ravulizumab plus best supportive care or matching placebo plus best supportive care. The treatment period is 26 weeks (open-label for Stage 1, and randomized, double-blind, and placebo-controlled for Stage 2) followed by a 26-week follow-up period.
