NCT ID: NCT06455709 Recruiting - Clinical trials for Myasthenia Gravis, Generalized

Markers of Favorable Response to Complement Inhibitors Therapy

OPTIMISE
Start date: June 5, 2024
Phase:
Study type: Observational

Myasthenia gravis is an autoimmune neurological disease caused by autoantibodies primarily directed against components of the postsynaptic membrane of the neuromuscular junction. Approximately 85% of patients have antibodies directed against the acetylcholine receptor (anti-AChR). Anti-AChR antibodies act through three distinct mechanisms: 1. Activation of the classical complement pathway: Formation of membrane-attack complexes (MACs) results in the destruction of the postsynaptic membrane. 2. Mechanical blockade: Anti-AChR antibodies block the acetylcholine binding site on its receptor. 3. Internalization and lysosomal degradation: Bivalent IgG causes cross-linking of adjacent receptors leading to internalization and degradation of AChRs (antigenic modulation). Patient mortality has significantly reduced due to effective treatments preventing severe exacerbations of myasthenic symptoms. In the past five years, the FDA and EMA have approved complement inhibitors for the treatment of generalized myasthenia gravis with anti-AChR antibody positivity. Eculizumab, a humanized monoclonal antibody, binds to the complement fragment C5, inhibiting its cleavage into C5a and C5b, and preventing the formation of the terminal complement complex C5b-9 (MAC). Currently, Eculizumab is approved in Italy for generalized myasthenia gravis associated with anti-acetylcholine receptor antibody positivity. This class of drugs is generally more effective than conventional immunosuppressive therapies, though it comes with higher costs. There is heterogeneity among patients in their response to complement inhibitor therapies. Currently, there is no specific evidence indicating which patients may benefit most from this class of treatments. Personalized therapy, considering the predominant pathogenic mechanisms of anti-AChR in individual patients, seems necessary. Interindividual heterogeneity in the autoantibody repertoire could underlie different responses to complement inhibitor therapies. For example, inhibition of the complement cascade in patients whose autoantibodies also block receptors might result in an unsatisfactory treatment response. Moreover, C5 gene polymorphisms could explain a lack of response to these new drugs. Investigating the immune, genetic, and cellular profile of myasthenic patients eligible for these new pharmacological therapies could be useful for identifying predictive markers of response and personalizing therapeutic choices.

NCT ID: NCT06454617 Recruiting - Osteoporosis Clinical Trials

Calibr-Ì: Comparative Evaluation of Phantomless Calibration Methods to Quantify Bone Mineral Density for Opportunistic Analysis of CT Scans

Calibr-Ì
Start date: June 6, 2024
Phase:
Study type: Observational

Osteoporosis is a systemic disease characterized by a reduction in bone mineral density (BMD) and qualitative alteration of the skeleton, resulting in increased bone fragility and fracture risk. The epidemiological impact of osteoporosis is extremely high. Proper diagnosis and clinical management of osteoporosis are critical to reducing the incidence of fragility fractures and preventing their complications. The diagnosis is generally confirmed by instrumental analysis of bone mineral density. The standard method is X-ray bone densitometry (DXA), which allows diagnosis based on criteria defined by the World Health Organization (WHO) by virtue of the T-score. DXA is a relatively quick and inexpensive examination with low exposure to ionizing radiation. However, this method has limitations in detecting fracture risk, and in addition, not all patients are properly referred for DXA services, which, among other things, require specific criteria to be reimbursed by the National Health System. Currently, computed tomography (CT) scanning is the most widely used three-dimensional diagnostic modality in clinical practice, and the number of investigations performed in high-income countries is continuously growing. Quantitative assessment of bone mineral density by CT is possible by proper calibration of the machine for the purpose of converting the CT numbers (or Hounsfield units) measured by the scanner into BMD units.

NCT ID: NCT06453421 Recruiting - Rehabilitation Clinical Trials

Pulmonary Rehabilitation in the Chronically Critically Ill Patient

Start date: February 10, 2023
Phase:
Study type: Observational [Patient Registry]

The goal of this observational study is to learn about the population of chronically critical ill patients who refer to respiratory rehabilitation units. The main questions it aims to answer are: - what are the clinical and pathophysiological characteristics of the population of chronically critical ill patients who refer to respiratory rehabilitation units after hospital admission with the need for prolonged invasive mechanical ventilation via tracheostomy? - what is the response of this patient population to respiratory rehabilitation treatment in terms of functional recovery, weaning from invasive mechanical ventilation, weaning from tracheostomy tube, mortality and return to home? - are there any appreciable indices at admission and/or in the first period of hospitalization which may have a prognostic significance both on short-term objectives (weaning from invasive mechanical ventilation, weaning from the tracheostomy tube) and in the medium-long term (survival, state of health)? Participants will be subjected to a rehabilitation and weaning program consisting of: - physical therapy, - speech therapy, - nutritional assessment and therapy, - in subjects on invasive mechanical ventilation at admission a program of weaning and, if needed, shift from invasive to Non-Invasive Ventilation will be performed.

NCT ID: NCT06452277 Not yet recruiting - Clinical trials for Advanced Non-small Cell Lung Cancer

A Study to Learn More About How Well BAY 2927088 Works and How Safe it is Compared With Standard Treatment, in Participants Who Have Advanced Non-small Cell Lung Cancer (NSCLC) With Mutations in the Genes of Human Epidermal Growth Factor Receptor 2 (HER2)

SOHO-02
Start date: June 24, 2024
Phase: Phase 3
Study type: Interventional

Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called human epidermal growth factor receptor 2 (HER2) mutations. Advanced NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body or that are unlikely to be cured or controlled with currently available treatments. HER2 is a protein that helps cells to grow and divide. A damage (also called mutation) to the building plans (genes) for this protein in cancer cells leads to a production of abnormal HER2 and therefore abnormal cell growth and division. The study treatment, BAY 2927088, is expected to block the mutated HER2 protein which may stop the spread of NSCLC. The main purpose of this study is to learn how well BAY 2927088 works and how safe it is compared with standard treatment, in participants who have advanced NSCLC with specific genetic changes called HER2 mutations. The study participants will receive one of the study treatments: - BAY 2927088 twice every day as a tablet by mouth, or - Standard treatment in cycles of 21 days via infusion ("drip") into the vein. The treatment will continue for as long as participants benefit from it without any severe side effects or until they or their doctor decide to stop the treatment. During the study, the doctors and their study team will: - take imaging scans, including CT, PET, MRI, and X-rays, of different parts of the body to study the spread of cancer - check the overall health of the participants by performing tests such as blood and urine tests, and checking - heart health using an electrocardiogram (ECG) - perform pregnancy tests for women - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.
