Active clinical trials for "Atrophy"

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).

Background: SBMA is an inherited chronic disease. It affects males in mid to late adulthood. It causes slowly progressive weakness of muscles and hand tremors. Researchers want to learn more about the effects of SBMA. Objective: To identify measurements that change over time in SBMA, including tests of muscle strength and function, as well as measurements of muscle and fat size. Eligibility: Men over the age of 18 both with and without a history of SBMA. Design: Participants will have a medical history, physical exam, and blood and urine tests. They will have neuromuscular ultrasound. They will have a lumbar puncture to obtain spinal fluid. For this, a needle will be inserted into the spinal canal in the lower back. Participants will have muscle strength and function tests. These tests may include pushing, pulling, rising from a chair and sitting back down, and/or walking. During these tests, they may wear an accelerometer (activity tracker) on their wrist. Participants will get an activity tracker to wear on their wrist for 10 days at home every 3 months. Participants with SBMA will also have lower limb magnetic resonance imaging (MRI) and optional whole-body MRI. They will have lung function tests. They will have speech and swallow tests. They will complete questionnaires. They may have optional body scans to measure bone density and lean body mass. They may have optional muscle biopsies. For biopsies, a needle will be used to take a small piece of muscle from the leg. Participants with SBMA will have 5 study visits over 2 years (every 6 months). Participants without SBMA will have 1 study visit.

Assessment of nano fat grafting combined with carbon dioxide laser resurfacing versus nano fat grafting alone in treating facial atrophic acne scars

Dominant Optic Atrophy (hereafter known as DOA) is a neurodegenerative pathology of the optic nerve inducing progressive loss of central visual field and visual acuity. There is currently no proven treatment for this disease. The metabolomics work of Pascal Reynier's team revealed a specific metabolomic signature of DOA in the plasma of patients. This metabolomic signature revealed a relative deficiency in nicotinamide compared to a control population, a vitamin compound (vitamin B3) known to be neuroprotective for the optic nerve and mitochondria. Note that the investigator have also identified this nicotinamide deficiency in primary open-angle glaucoma and Leber's hereditary optic neuropathy, the other most common cause of hereditary optic neuropathy, these three optic nerve conditions sharing a common pathophysiological mechanism of mitochondrial deficit. In addition, an American team demonstrated the high neuroprotective power on the optic nerve of nicotinamide in a mouse model of glaucoma. These arguments converge towards the potential therapeutic interest of this vitamin in degenerative pathologies of the optic nerve. This is encouraged by the fact that two randomized clinical trials have confirmed a benefit of nicotinamide in glaucoma. The objective of this pilot study is to test the tolerance and efficacy of nicotinamide in DOA and DOA+ patients.

This is a Phase 2, double-blind, parallel-group, placebo-controlled study to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of multiple doses of ONO-2808 in patients with MSA. This is the first study of ONO-2808 in patients with MSA.

Vulvovaginal skin conditions, namely vaginal atrophy, lichen sclerosus, lichen simplex chronicus and lichen planus affecting the female adult population will be treated with a novel gel dressing to test the short- and long-term safety and efficacy of the device.

This is an open-label, single-arm, multicenter clinical study to evaluate the effectiveness and safety of risdiplam administered in pediatric participants with SMA and 2 SMN2 copies who previously received onasemnogene abeparvovec and experience a plateau or decline in function. Participants to be enrolled are children <2 years of age genetically diagnosed with SMA.

The primary objective of the clinical investigation is to demonstrate successful clinical use of the ThecaFlex DRx™ System in delivering nusinersen in subjects with spinal muscular atrophy (SMA). All enrolled subjects will undergo implantation of the investigational device (ThecaFlex DRx™ System) and will be followed for 12 months after receiving the implant. The 12-month data will be used to assess the primary endpoint support a Pre-Market Approval (PMA) application.

The first cure for Spinal Muscular Atrophy (SMA; Nusinersen) has been approved by FDA in 2017. Although it improves the clinical picture of most SMA patients, not all exhibit the same response to treatment. In this project the aim will be: i. identifying cell-free SMN circular RNAs (circRNAs) in body fluids of SMA patients as potential biomarkers before and after Nusinersen; ii. evaluating their prognostic power as predictors of the clinical response of SMA patients to Nusinersen; iii. identifying human intronic polymorphisms that affect SMN circRNAs biogenesis and impact on the efficacy of Nusinersen. The results obtainable with this project will evaluate if different concentration of cell free SMN circRNAs in SMA patients could underlie the genotype-phenotype mismatch, usually observed, and the reduced response of a subset of SMA patients to therapy. Our research could highlight the need for these of combinatorial 'SMN-plus' and "personalized" therapies that account for individual differences.

The goal of this clinical trial is to compare the effects of resistance training (RT) preconditioning vs no training on disuse-induced atrophy and post-disuse resistance training in young healthy individuals. The main questions it aims to answer are: To determine if performing RT prior to a period of disuse enhances the regain of strength, skeletal muscle size, and skeletal muscle quality while performing RT after a period of disuse. To determine if performing RT prior to a period of disuse dampens the maladaptive effects of disuse on muscle size, muscle quality, and strength. To determine the anabolic and proteolytic mechanisms underpinning the observed outcomes. Participants will: Perform either 6 weeks of resistance training or maintain an untrained lifestyle Perform 2 weeks of limb immobilization induced disuse of a randomized leg Perform 6 weeks of resistance training Researchers will compare the resistance training preconditioning condition vs the non-trained condition to see if resistance training prior to a period of disuse is beneficial during the disuse period and in the return to training period on skeletal muscle size, strength, and underpinning molecular markers.
