Active clinical trials for "Atrophy"

The goal of this clinical trial is to compare measurements of geographic atrophy (GA) area between several types of imaging, in order to assess accuracy. The main question to answer is which imaging device provides measurements that are most similar to the standard of care device. Participants will be patients of a retina doctor at University Station Eye Clinic with geographic atrophy, and can expect to be in the study for 60-75 minutes.

This study will evaluate the pharmacokinetics (PK) and safety of risdiplam in participants with spinal muscular atrophy (SMA) under 20 days of age at first dose.

Fat grafting has been gaining popularity over the past decade. It is now commonly used for breast augmentation and reconstruction, however a major challenge remains the high rate and unpredictable rate of fat resorption post-operatively, leading to volume loss and patient dissatisfaction. Currently there is no consensus on the ideal technique to process donor fat to minimize the rate of resorption. Our study aims to compare two common processing methods to determine if one is superior for fat volume retention.

This randomized phase IIb trial studies how well curcumin works in preventing gastric cancer in patients with chronic atrophic gastritis and/or gastric intestinal metaplasia. Curcumin is an antioxidant compound found in plants that may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

The goal of this study is to determine the impact of pre-diabetes and type 2 diabetes on muscle atrophy during a period of bed rest and recovery of muscle mass, strength, and physical function following bed rest.

The primary objectives of the study are to obtain clinically meaningful data on survival and outcomes of all the patients with spinal muscular atrophy (SMA) 5q types 1 through 4 (according to international classification), being followed in the reference centers of the disease in France between September 1, 2016 and August 31, 2024. The registry will collect retrospectively and prospectively the longitudinal data of the long-term follow-up for child and adult patients, under real life conditions of current medical practice, in order to document the clinical evolution of patients (survival, motor, respiratory, orthopedic and nutritional), the conditions of use of the treatments, the mortality rates of treated and untreated patients, the tolerance of the treatments, adverse events in order to better define their places in the therapeutic strategy.

Spinal Muscular Atrophy (SMA) is a life-threatening disease in infancy that is caused by inactivating mutations in the Survival Motor Neuron 1 (SMN1) gene1,2. SMN1 mutations lead to deficiency in SMN protein, which results in degeneration of motor neurons in the spinal cord, progressive muscle weakness and atrophy. The almost identical SMN2 gene does not suffice SMN function, because skipping of exon 7 in its mRNA yields an unstable protein. Nevertheless, SMN2 represents a disease modifier gene and increasing its expression or rescuing its splicing defect have long been considered elective strategies for SMA1,2. After substantial translational research efforts, the first therapies eliciting clinical benefits for SMA patients have recently become available3. Nusinersen, an antisense oligonucleotide (ASO), and Risdiplasm, a small molecule, bind the SMN2 RNA and promote splicing of exon 7. On the other hand, Zolgesma, an adeno-associated virus delivering the SMN1 gene (scAAV9-SMN), bypasses the need to correct the splicing defect. Nevertheless, none of these therapies currently represents a complete cure for patients, because not all of them respond equally and in a significant portion of patients the symptoms are attenuated but not corrected3. It is believed that early treatment, possibly at a pre-symptomatic stage, would positively affect the clinical response and may significantly improve patient's management. However, another critical point is the current lack of information on the long-term efficacy and safety of the current treatments4. In this scenario, it is likely that further elucidation of the biological functions of the SMN genes and the identification of robust biomarkers for stratification of patients will set the ground for more "personalized" therapies, which may account for the clinical variability observed in patients and help improving the therapies in use.

This study will assess the safety and efficacy of ATH434 in participants with a clinical diagnosis of Multiple System Atrophy

The purpose of the study is to systematically characterize the clinical course of the progressive neuropathy and optic atrophy observe in pediatric and adult patients with biallelic mutations in the ferredoxin reductase gene.

The goal of this study is to perform a quantitative assessment of the psychometric properties of the Vulvovaginal Atrophy Questionnaire (VVAQ), a novel patient reported outcome measure (PROM), through a REDCap survey of menopausal women with and without symptomatic vulvovaginal atrophy (VVA)/genitourinary syndrome of menopause (GSM).
