There are about 21062 clinical studies being (or have been) conducted in Italy. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to evaluate the efficacy and safety of mirikizumab as maintenance therapy in participants who completed as clinical responders in the prior 12-week induction study LUCENT-1 (NCT03518086).
The study purpose is to evaluate the morphological, functional and electrophysiological characteristics of the right ventricle before and after ajmaline in patients diagnosed with Brugada syndrome as well as to correlate CMR findings and substrate size.
RATIONALE: Cardiac resynchronization therapy (CRT) is known to improve cardiac performance and to reduce morbidity and mortality in reduced-ejection fraction heart failure (HFrEF) despite optimal medical therapy (OMT). Several studies have shown that patients with with left bundle branch block (LBBB) respond favourably to CRT, whereas there is less certainty about non-LBBB morphology. Specifically, whether patients with right bundle branch block (RBBB) and HFrEF benefit from CRT is unclear. Some studies suggest lack of favourable outcomes. It follows from this that VVI implantable defibrillator are implanted in most RBBB patients.On the other hand right ventricular bifocal stimulation could be useful as an alternative approach in patient with RBBB. It consists of two endocardial leads implanted in right ventricle. The first lead is implanted in His bundle area, and the second lead is in the right ventricle apex. In this way bifocal pacing could decrease the inter- and intraventricular delays, thus improving left ventricular hemodynamics. However no specifically randomized studies are designed to date. PURPOSE: To demonstrate the superiority of right ventricular bifocal stimulation over placebo (VVI implantable defibrillator) in RBBB and HFrEF despite OMT. DESIGN Multicenter prospective randomized, double blind cross-over study. MASKING Investigator responsible for device programming is masked from having knowledge about clinical, functional, and echocardiographic data. On the other hand echocardiographist is masked from having knowledge about stimulation mode. Patients are masked from having knowledge about their clinical, functional, and device data. POPULATION At least fifty patients would be enrolled. The enrollment period should be one year. Study overall duration should be two years. ELIGIBILITY CRITERIA RBBB and HFrEF (left ventricular ejection fraction ≤35%) in sinus rhythm, in NYHA class II-III or ambulatory IV despite OMT. EXCLUSION CRITERIA -Refusal or withdrawal of informed consent.Renal failure (glomerular filtration rate ≤ 60 ml/min).Life expectancy < 12 months.Active neoplasm.Permanent atrial fibrillation.40 days following acute coronary syndrome.Atrio-ventricular block (from second degree AV block).Valvular heart disease with surgery indications. PROTOCOL Each patient undergoes baseline assessment. Pharmacological therapy, hospitalization,NYHA functional class, QRS complex informations, type of heart disease and comorbidities are collected. Quality of life (QOL) is defined by Minnesota Living with Heart Failure questionnaire. Functional capacity is assessed by 6MWT (optionally by cardiopulmonary exercise test). Trans-thoracic echocardiogram is performed, analyzing: left-ventricle diameters and volumes, left-ventricle ejection fraction (LVEF), left atrial diameter and area, TAPSE,valvulopathy,systolic pulmonary artery pressure. All patients undergo bifocal right ventricular resynchronization therapy: right atrial lead is implanted, whereas the first ventricular lead is placed in His bundle area, and the second ventricular lead in the right ventricle apex. Then the leads are connected to the respective channels of a CRT-D generator.After the implant, all devices are programmed in VVI mode. After the first 40±10 days (first f-up) patients are 1:1 randomized to VVI mode 40 beats/minute (placebo arm) or bifocal DDD-mode 60 beats/minute (with VV delay 0 msec and optimal AV delay). After six months (second f-up) a clinical and instrumental assessment equal to baseline is performed, as well as devices electrical parameters control. Then arms cross-over is performed (from VVI-mode to bifocal DDD-mode and vice versa). At 12 months (end of follow-up) an evaluation equal to that performed at 6 months is assessed. Echocardiographic data are unravelled to the investigator responsible for device programming. In this way the stimulation mode able to determine the best clinical improved (VVI or bifocal DDD mode) is programmed and the study closes. PRIMARY ENDPOINT The main assumption is that bifocal stimulation can increase of at least 20% the distance walked during 6MWT in respect of baseline and VVI-mode.The primary endpoint is the distance walked (expressed by meters) during 6MWT, as assessed at baseline, 6-months follow-up and 12 months follow up. Specifically changes in 6MWT observed during bifocal DDD-mode compared to baseline and to VVI mode would be significative if there is an increase of at least 20%. SECONDARY ENDPOINT Secondary endpoint is bifocal stimulation therapy response, defined by at least one of the following criteria, evaluated at baseline, 6-months follow-up and 12 months-follow-up in comparison to baseline and VVI mode: NYHA functional class improvement; changes in 6MWT, defined by an increase in distance walked major or equal to 30%; LVEF improvement major or equal to 25%;Left ventricular telesystolic volume reduction major or equal to 15%
This study is a prospective, multicenter, open-label, single-arm effectiveness and safety study in participants with progressive multiple sclerosis (PMS).
Primary Objective: To determine the effect of venglustat on the rate of total kidney volume (TKV) growth (Stage 1) and estimated glomerular filtration rate (eGFR) decline in participants at risk of rapidly progressive Autosomal Dominant Polycystic Kidney Disease (ADPKD) (Stage 2). Secondary Objectives: - To determine the effect of venglustat on the rate of renal function decline (Stage 1) and on the rate of TKV growth (Stage 2). - To evaluate the pharmacokinetics (PK) of venglustat in ADPKD participants (Stages 1 and 2). - To determine the effect of venglustat on pain and fatigue, based on participant reported diary (Stages 1 and 2). - Safety/tolerability objectives: - To characterize the safety profile of venglustat (Stages 1 and 2). - To evaluate the effect of venglustat on mood using Beck Depression Inventory II (BDI-II) (Stages 1 and 2). - To evaluate the effect of venglustat on the lens by ophthalmological examination (Stages 1 and 2).
In medical practice, a combination of clinical exam, electrocardiograms, circulating biomarkers, and imaging is used to gain insights on the prognosis after myocardial infarction. Novel molecular non-invasive tools are needed that help clinicians overcome the adverse events of post-myocardial infarction remodelling and thereby achieve improved therapy for its prevention. Coagulation factor XIII (FXIII) decay has been linked to major adverse cardiac events (MACE) in patients with acute coronary syndromes. Given the correlation between both intramyocardial haemorrhage and microvascular damage with acute phase complications in ST-elevation myocardial infarction, we hypothesise that excessive FXIII decay within the first week may predict acute phase outcomes in these patients. If this holds true, FXIII determination could be used as diagnostic and prognostic tool.
This study will compare DS 8201a to standard treatment. Participants must have HER2 breast cancer that has been treated before. Their cancer: - cannot be removed by an operation - has spread to other parts of the body
This is a study of trastuzumab deruxtecan, which was approved by the FDA (in December 2019) for the treatment of HER2-positive unresectable or metastatic breast cancer following two or more prior anti-HER2 based regimens. Participants will receive this study drug along with a cancer drug, an immune checkpoint inhibitor, anti-PD1, called nivolumab. The study will be done in two parts: - Part 1 is to identify the recommended dose to use for treatment. - Part 2 is to find out how well the combination works, and how safe and tolerable it is.

Altered passive eruption (APE) is an anatomical condition that is frequently diagnosed in periodontal clinical practice, especially for the ever-increasing demand of patients for the aesthetic improvement of their smile. In addition to its aesthetic value, however, altered passive eruption could also affect gingival and periodontal health. In fact, in the case of plaque accumulation, the altered passive eruption (APE) is likely to be a predisposing factor for a more rapid progression of gingivitis with higher inflammation indexes (Angulated Bleeding Score - AngBs and Modified Gingival Index - mGI). Notwithstanding, even if gingivitis in patients with altered passive eruption is developed much more rapidly, thorough home oral hygiene and plaque control conduces to complete clinical recovery. Further studies with a large number of patients are required to confirm the correlation between altered passive eruption and periodontal diseases.
