NCT ID: NCT05511103 Active, not recruiting - Rare Neuropathy Clinical Trials

A Cohort of Acute, Ischemic and Rare Neuropathies

CAIRN
Start date: August 25, 2022
Phase:
Study type: Observational

Neuropathies are defined as the clinical, electrical, biological and histological manifestations of peripheral neuron damage. They represent a heterogeneous group of disorders and are responsible for disabling sensory and motor disorders. Their diagnosis is based on a set of clinical arguments confirmed by the electromyogram. This allows to specify the site of the damage, its severity, and to follow the evolution of the disease. To date, the diagnosis of peripheral nerve injury secondary to occlusion of arterial trunks is rarely evoked; its clinical, electromyographic and prognostic characteristics are poorly known. Indeed, the rare cases reported in the literature are from vascular specialties, with little data on neurological symptoms, neurophysiological diagnostic elements and prognosis. However, these unrecognized and underdiagnosed neuropathies are sometimes indicative of severe vascular damage for which urgent management is necessary. Neurological symptoms should then be treated as warning signs and the correct recognition of the early ischemic vascular etiology may lead to an optimized medical management. The objectives of this study will be to describe the clinical presentation of these neuropathies, to discuss their electrophysiological diagnostic characteristics, to compare the demographic data with those from the literature, and to evaluate the functional prognosis of these attacks. A better knowledge of this rare etiology of neuropathy would allow to better inform the patients and to optimize the diagnostic and therapeutic management.

NCT ID: NCT05508074 Active, not recruiting - Clinical trials for Amyotrophic Lateral Sclerosis

Treatment Combining Riluzole and IFB-088 in Bulbar Amyotrophic Lateral Sclerosis (TRIALS Protocol)

Start date: December 2, 2022
Phase: Phase 2
Study type: Interventional

Prospective, international, randomised, double-blind, placebo controlled, multicentre, parallel group study. Patients will be randomised in a 2:1 allocation ratio to receive either IFB-088 + riluzole 100 mg or placebo + riluzole 100 mg. This clinical trial is an exploratory study, designed to show a signal of efficacy of IFB-088 through ALSFRS-R, MITOS and King's College. Respiratory function will be followed through SVC. Biomarkers and quality of life will also be evaluated throughout the study. Patients will be treated over a 6-month period. After a screening/consent visit, patients will undergo clinic visits at randomisation (V0), at 2 weeks (V1), and at months 1 (V2), 3 (V3) and 6 (V4). One week after V0, the patient will undergo urine analysis (dipstick)and blood sampling for measurement of creatinine , as well as blood sampling for measurement of creatinine and calculation of eGFR at months 2, 4 and 5. At the V2 visit, in addition to other assessments, patients will undergo blood sampling for PK measurements and urine sampling for crystalluria examination. Blood and urine chemistry, as well as physical examination and vital signs assessment to assess safety will be performed at each visit for safety purpose and crystalluria examination will be repeated at the follow-up visit, performed one month ± one week after V4.

NCT ID: NCT05501873 Active, not recruiting - Atrial Fibrillation Clinical Trials

Real World Data Collection in Subjects Treated With the FARAPULSE Pulsed Field Ablation System

FARADISE
Start date: March 24, 2023
Phase:
Study type: Observational [Patient Registry]

The goal of any novel design or therapeutic strategy to treat atrial fibrillation is to restore normal sinus rhythm and to reduce or eliminate the symptoms due to rapid atrial response. Boston Scientific has developed the FARAPULSEā„¢ Pulsed Field Ablation therapy that uses irreversible electroporation to induce cell death. This Registry is intended to obtain purely observational and prospective real world data and to provide continued evidence on the safety and effectiveness when the FARAPULSEā„¢ pulsed field ablation System is used per hospitals' standard of care.

Start date: November 7, 2022
Phase: Phase 2
Study type: Interventional

This purpose of this study is to establish proof of concept of AG-946 in participants with LR-MDS in Phase 2a and to compare the effect of AG-946 versus placebo and to detect a dose response for erythroid response in participants with LR-MDS in Phase 2b.

NCT ID: NCT05486130 Active, not recruiting - Clinical trials for Ventilator Associated Pneumonia

PREdiction of CEphalosporinase Producing Enterobacteria During Ventilator-associated Pneumonia for Therapeutic Stewardship

Start date: July 18, 2022
Phase:
Study type: Observational

Ventilator-associated pneumonia is the leading cause of nosocomial infection in the ICU. Cephalosporinase-producing Enterobacteriaceae have an increasing incidence. Infections in cephalosporinase-producing patients require the use of Cefepime during probabilistic antibiotic therapy, the repeated use of which will lead to a significant risk of selection of resistant mutants. The involvement of cephalosporinases being infrequent, the prediction of their presence during a VAP would make it possible to reduce the consumption of Cefepime and thus to take part in the prevention of selection of bacterial mutants resistant to beta-lactams. The main objective of the research is to determine the risk factors for the involvement of cephalosporinase-producing enterobacteria during episodes of ventilator-associated pneumonia (VAP) in hospitalized patients. The secondary objectives are to describe the epidemiology of cephalosporinase-producing enterobacteria in the ICU and to compare the risk factors for the presence of a cephalosporinase-producing germ not without its production being derepressed with those present in situations of cephalosporinase derepression.

NCT ID: NCT05477407 Active, not recruiting - HIV Infections Clinical Trials

Adipose Tissue After Switch to Doravirine

ADDORE
Start date: September 15, 2022
Phase: N/A
Study type: Interventional

Integrase-strand-transfer-inhibitors (INSTIs) based regimens have been associated with body weight gain and increase in total body adipose tissue (AT). Whereas there is by now no clear understanding of the mechanisms that induce these changes, we have observed modifications of AT in vitro, in animals models or in vivo in obese patients with raltegravir (RAL) and dolutegravir (DTG) with the presence of increased peri-adipocyte fibrosis and high levels of collagen VI that have been associated with poor metabolic prognoses together with cellular insulin resistance and decreased adiponectin secretion. One major clinical question is whether such AT abnormalities are reversible. Doravirine (DOR), the most recent available Non-Nucleosidic Reverse Transcriptase Inhibitor (NNRTI) drug, has an excellent metabolic profile and as a NNRTI is expected to induce neither changes in fat tissue distribution nor changes in body weight. Tenofovir disoproxil fumarate (TDF) is associated with a protective lipid profile and, unlike tenofovir alafenamide (TAF) which seems to potentiate weight gain in combination with INSTI, has not been associated with weight gain. One major clinical question is whether such AT abnormalities are reversible. Doravirine, the most recent available NNRTI drug, has an excellent metabolic profile and as a NNRTI is expected to induce neither changes in fat tissue distribution nor changes in body weight. Tenofovir DF is associated with a protective lipid profile and, unlike TAF which seems to potentiate weight gain in combination with INSTI, has not been associated with weight gain. We hypothesized that modifications in morphology and function of the adipose tissue in patients with significant weight gain under an INSTI-based regimen could be improved after switching to the triple drug TDF/Emtricitabine/DOR and that fat increase and body weight will be stopped or reversed. This pathogenesis study aimed to evaluate potential changes in adipose tissue after switching from an INSTI-based regimen (Raltegravir or Dolutegravir or Bictegravir) to TDF/Emtricitabine/DOR. Each patient will be evaluated with an adipose tissue biopsy performed before (D0) and after a 48 week switch (W48) from an INSTI-based regimen to the non INSTI-based regimen combining TDF/3TC/Doravirine. With a number of 22 patients at D0, a total of 20 patients with paired adipose tissue biopsies are expected at W48. The antiretroviral therapy with TDF/emtricitabine/Doravirine will be used as routine practice recommends.
