NCT ID: NCT05633563 Completed - Clinical trials for Mitochondrial Pathology

The Effect of Trimetazidine on Mitochondrial Function, Myocardial Performance, and Invasive Hemodynamics in Patients Diagnosed With Wild-Type Transthyretin Cardiac Amyloidosis

CACTuS - TMZ
Start date: October 1, 2021
Phase: Phase 4
Study type: Interventional

Wild-type transthyretin cardiac amyloidosis (ATTRwt) is a deposition disorder in which one of the proteins of the body misfolds and accumulates at various places in the body, including the heart, leading to both mechanical and cellular damage. The gradual development of the disease will ultimately lead to heart failure and death The protein which deposits in the heart of patients, damages both the heart mechanically as the myocardium becomes rigid and hypertrophic over time but also at the cellular level. Cell damage can be observed by elevated blood tests for cell damage (Troponin) and during exercise tests that show patients' hearts burning oxygen inefficiently when exposed to physical stress compared with the hearts of healthy individuals . No one has, however, intimately studied this cellular damage. Vastarel® (Trimetazidine, TMZ) is an already known drug for the treatment of chest pain. The mechanism of action indicates that it may have an effect on patients with cardiac amyloidosis. The study aims to investigate the effects of TMZ on the mitochondrial function, myocardial performance, and invasive hemodynamics in patients with ATTRwt with a randomized, double-blinded, crossover-trial.

NCT ID: NCT05565144 Completed - Stroke Clinical Trials

Brain Hemorrhage and Functional Outcome in Stroke Patients With CAA Features on Pre-thrombolysis MRI Treated With Intravenous Thrombolysis (Thrombolysis in CAA) ( Thromb in CAA )

Thromb in CAA
Start date: October 2, 2022
Phase:
Study type: Observational

Background: In stroke patients treated with intravenous thrombolysis (IVT), presence and high number of strictly lobar cerebral microbleeds (compatible with cerebral amyloid angiopathy, CAA) seems to be associated with increased risk of hemorrhagic transformation, symptomatic hemorrhagic transformation, remote hemorrhage, and poor functional outcome. Some of these reported CAA patients with cerebral microbleeds also had chronic lobar intracerebral haemorrhage. Few data is available on IVT-treated CAA patients showing cortical superficial siderosis. There are no reports studying factors associated with brain hemorrhagic complication or functional outcome inside a group of IVT-treated CAA patients. Our aim was to evaluate brain hemorrhagic complications on 24h-CT and functional outcome after IVT in stroke patients with CAA features on pre-IVT MRI. Methods: In our stroke center, IVT decision in patients with CAA MRI features is left at the discretion of the treating physician. We retrospectively screened pre-IVT imaging of 959 consecutive IVT-treated stroke patients (between January 2015 and July 2022) without ongoing anticoagulation therapy for probable CAA MRI features defined by modified Boston criteria. After exclusion of 119 patients with lacking MRI (n=47), with MRI showing motion artefacts (n=49) or with alternative chronic brain hemorrhage cause on MRI (n=23), 15 IVT-treated patients with probable CAA on pre-IVT MRI were identified. In these 15 patients, clinical, biological and MRI characteristics were compared between patients with vs. without post-IVT hemorrhage and between patients with poor (MRS 3-6) vs. good (MRS 0-2) functional outcome at discharge.

NCT ID: NCT05560555 Completed - Polyneuropathy Clinical Trials

NCT ID: NCT05486897 Completed - Clinical trials for Cerebral Amyloid Angiopathy

Periventricular White Matter Hyperintensities in Cerebral Amyloid Angiopathy and Hypertensive Arteriopathy

PVWMH
Start date: September 5, 2022
Phase:
Study type: Observational

White matter hyperintensities (WMH) are one of the small vessel disease-related MRI characteristics of both cerebral amyloid angiopathy (CAA) and hypertensive arteriopathy (HA). WMH tend to show a peri-basal ganglia pattern in HA, whereas a multiple subcortical spots pattern can be observed in CAA. Periventricular WMH (PVWMH) have been reported to be posterior predominant using a semiautomated segmentation method and logarithmic transformation, not used in daily clinical practice. In these studies including CAA patients, patients initially presented with haemorrhage-related symptoms. In another study analysing PVWMH and cerebral amyloid evidence in patients with mild cognitive impairment, frontal PVWMH burden was associated with high uptake on florbetapir-PET whereas parietal and occipital PVWMH burden was associated with low CSF-amyloid-beta. The aim of this study is the descriptive comparative analysis of the distribution of PVWMH between CAA and HA patients with radiological tools available in daily practice.

NCT ID: NCT05475158 Completed - Alzheimer Disease Clinical Trials

Comparison of OCTA Factors in Patients With or Without Amyloid Pathology: A Prospective Study

Start date: September 1, 2019
Phase:
Study type: Observational

To compare alternation of retinal microcirculation within the macula and optic disc in patients with dementia, mild cognitive impairment (MCI), and cognitively healthy subjects who had positive amyloid biomarkers (Aβ +) or not, using optical coherence tomography angiography (OCTA).

NCT ID: NCT05394636 Completed - Clinical trials for Cerebral Amyloid Angiopathy

Cerebellar Superficial Siderosis in Cerebral Amyloid Angiopathy

CSS
Start date: June 1, 2022
Phase:
Study type: Observational

Cerebellar superficial siderosis (SS) has been recently reported to be present in about 10% of both hereditary (n=50) and sporadic (n=46) cerebral amyloid angiopathy (CAA) patients on 3T MRI using susceptibility-weighted imaging (SWI) in the majority of patients. In that study, cerebellar SS was associated with a higher number of supratentorial lobar and superficial cerebellar macrobleeds (although cerebellar SS was not directly located adjacent to these cerebellar macrobleeds). It is unclear if cerebellar SS is caused by in situ leakage of cerebellar leptomeningeal vessels or rather represents hemorrhagic diffusion from cerebellar parenchymal micro/macrobleeds or from supratentorial bleeding sources via the tentorium cerebelli (TC).

NCT ID: NCT05260203 Completed - Multiple Myeloma Clinical Trials

MargheRITA (Remote Intelligence for Therapeutic Adherence)

MargheRITA
Start date: June 4, 2022
Phase: N/A
Study type: Interventional

It is essential to improve clinical efficiency and management of hematological and oncological patients treated on an outpatient basis. The most promising operative way to achieve this result is the development of tele-oncology platforms, that allow not only a telemedicine visit, but also the patient support in the daily management of the disease and related disorders, as well as treatments and their complications. In this perspective, the RITA communication platform should be able to support the patient, the caregiver, the physician and the general practitioner in the management of the disease and its treatments.

NCT ID: NCT05233163 Completed - Clinical trials for Transthyretin Amyloid Cardiomyopathy

SGLT2 Inhibitors in Transthyretin Amyloid Cardiomyopathy

Start date: March 14, 2022
Phase: Phase 4
Study type: Interventional

This is a single center, single arm, prospective, 12 week open label pilot trial of the sodium-glucose cotransporter 2 inhibitor (SGLT2i), empagliflozin 10 mg oral daily, in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). The target population for enrollment will be subjects with ATTR-CM and either non-insulin dependent diabetes mellitus or chronic kidney disease. The primary aim will be to assess the safety and tolerability of empagliflozin 10 mg oral daily in subjects with heart failure secondary to ATTR, which remain unexplored. The accrual target is 15 subjects. Consented subjects will be evaluated for safety and tolerability of study drug, empagliflozin 10 mg oral daily, over a period of 12 weeks. Subjects will undergo a total of 6 study visits: 3 in-person and 3 telephone follow-ups.
