Filter by:The overall goal of this natural history study is to define the key LGMD2i phenotypes as measured by standard clinical outcome assessments (COAs), and to validate a muscle biomarker for LGMD2i to support therapeutic development.
The purpose of this study is to evaluate the safety and efficacy of oral weekly glucocorticoid steroids in patients with Becker Muscular Dystrophy (BMD), an inherited disorder in which patients experience weakness of the legs and pelvis, and Limb Girdle Muscular Dystrophy (LGMD), an inherited disorder in which patients experience progressive muscular weakness predominately in their hip and shoulders. The primary objective is safety which we the investigators will measure using laboratory testing and forced vital capacity (FVC), a breathing test that measures the strength of your lungs. The secondary objective is efficacy which will be measured by a change in MRI muscle mass, improved muscle performance, and quality of life. The investigators hypothesize that patients who receive oral weekly glucocorticoid steroids will have improviements in strength and quality of life compared to their baseline. Furthermore, the investigators anticipate that oral weekly glucocorticoid steroids will not have significant adverse impact on patients.
ATYR1940-C-006 is a multi-national, multicenter study being conducted at centers in the United States (US) and Europe who participated in Study ATYR1940-C-003 (Stage 1 only) or Study ATYR1940-C-004 (that is, the parent studies).
POMT2 mutation is known to cause Walker Warburg Syndrome and Muscle-Brain-Eye syndrome. Recently it has been connected to limb girdle muscular dystrophy (LGMD), a disorder characterized by muscle weakness and atrophy of the proximal muscles of the shoulder and pelvic girdles. LGMD is classified based on its inheritance pattern and genetic cause into more than 31 different types. LGMD with POMT2 mutations is a new phenotype - type 2N. Very few patients with the LGMD2N phenotype has been reported. In this study, the investigators examine five new cases with the LGMD phenotype. The primary aim is to examine the muscle involvement using MRI.
Limb girdle muscular dystrophies (LGMD) are a very heterogeneous group of muscle disorders characterized by muscle weakness and atrophy of the proximal muscles of the shoulder and pelvic girdles. LGMD is classified based on its inheritance pattern and genetic cause into more than 31 different types. A new type - type 2T has been found. The genetic cause of type 2T is mutations in Guanosine Diphosphate (GDP)-mannose pyrophosphorylase B (GMPPB). Mutations in GMPPB can also cause Congenital muscular dystrophies (CMD). Only 41 patients with mutations in GMPPB has been reported. In this study, the investigators examine five new cases with the LGMD phenotype. The primary aim is to examine the muscle involvement using MRI.
The study will include 120 participants aged 8 and up with Duchenne, Becker, or autosomal recessive limb-girdle (specifically: LGMD 2C-2F and 2I) muscular dystrophies that have no clinical cardiac symptoms. Participants will be randomized to one of four arms: Arm 1 CoQ10 alone, Arm 2 Lisinopril alone, Arm 3 CoQ10 and Lisinopril or Arm 4 No study medication. Randomization will be stratified by ambulatory status and corticosteroid use. The primary outcome for the study is the myocardial performance index (MPI), measured by standard Doppler echocardiography. The study will last 24 months with visits at Months 0.5,1.5, 6, 12, 18 and 24. Following completion of the Clinical Trial of Coenzyme Q10 and Lisinopril, participants will be offered participation in a companion protocol: PITT1215 A Natural History Companion Study to PITT0908: Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies. The objective of this study is to evaluate the longitudinal natural history of DMD, BMD, and LGMD2I and to evaluate the effects of Coenzyme Q10 and/or Lisinopril on prevention of cardiac dysfunction in these disorders.This will be an 18-month longitudinal natural history study designed to accompany the Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies.
This protocol will exploit novel state of the art cardiovascular magnetic resonance techniques to examine important changes in the heart in children with muscular dystrophy. The purpose of this study is to compare cardiac magnetic resonance (CMR) with the collected cardiac outcome data obtained in protocol: PITT1109 - Cardiac Outcome Measures in Children with Muscular Dystrophy.
The purpose of the research study is to evaluate different cardiac measures that are obtained by echocardiographic tests in patients with muscular dystrophy.
Muscular dystrophies are inherited disorders in which the skeletal and heart muscles become progressively weaker, sometimes leading to permanent disability. Current treatments aim to control symptoms as much as possible, but there is no cure. Gene therapy, in which defective genes causing the disorder are corrected, is a potential treatment option and is in the process of being developed for muscular dystrophies. This study will determine the safety and feasibility of a particular delivery method for gene therapy that could be used in the future to treat people with muscular dystrophies. Only normal saline, and no active treatment, will be used in this study.
The objective of this study is to identify and maintain a registry of well-characterized limb-girdle muscular dystrophy (LGMD) patients. Patients seen as part of this study may be candidates for future treatment trials based on their defined genetic classification of LGMD. In the course of this study, the investigators will perform a muscle biopsy and DNA testing in an unlimited number of patients with clinically diagnosed LGMD. The genetic testing will be extended to the family of the study subject in order to better understand true genetic defect.
