Weekly Steroids in Becker Muscular Dystrophy and LGMD
The purpose of this study is to evaluate the safety and efficacy of oral weekly Prednisone. The primary objective is safety. The secondary objective is efficacy which will be measured by a change in MRI muscle mass, improved muscle performance, and quality of life.

Natural history study in LGMD2I
Multi-center natural history study to better understand the disease physiopathology. The study will last 24 months and will take place in the UK, France, and Denmark.
Enrollment is ongoing
– France, Denmark, and UK
Natural history study in LGMD2I in Norway
Key goals are to establish the natural history of limb-girdle muscular dystrophy type 2I (LGMD 2I) and identify feasible and sensitive tools and biomarkers to measure disease affection and progression, determine the Norwegian LGMD 2I prevalence, carrier frequency and genotypes, and to assess health-related quality of life in the Norwegian LGMD 2I population. It is a single-center study with Norwegian nationwide enrollment.
Enrollment is ongoing

Clinical Trial Readiness for the Dystroglycanopathies
LGMD2I is a form of dystroglycanopathy. This study will describe the early signs and symptoms of the dystroglycanopathies and LGMD2I, and gather information that is critical to design future clinical studies on promising treatments.
Enrollment is ongoing
A Study of Deflazacort (Emflaza®) in Patients with LGMD2I
This study is designed to evaluate the safety and efficacy of deflazacort in participants with LGMD2I. The study will include a 26-week double-blind, randomized, placebo-controlled period followed by a 26-week open-label extension period during which all participants will receive deflazacort.
Enrollment is ongoing
– USA, Denmark, and Germany
Wellness and Quality of Life Survey of Patients with LGMD2I
The objective is to gather information on disease status, habits, diet, and exercising routines, natural therapies and supplements people affected with LGMD2I use to improve their quality of life.

A Trial of PF-06252616 in Ambulatory Participants With LGMD2I
The investigational product PF-06252616 is a humanized anti myostatin monoclonal antibody that neutralizes myostatin (GDF8). Myostatin has been shown to stop the growth of muscles. It is thought that neutralizing myostatin may restart muscle growth. PF-06252616 is in development for the treatment of LGMD2I to preserve and/or improve muscle function.
This study is testing the safety, tolerability, Pharmacokinetics and Pharmacodynamics of PF 06252616 following repeat IV doses in ambulatory adults with LGMD2I.

Muscle MRI in Becker Muscular Dystrophy and in Limb-girdle Muscular Dystrophy Type 2I
MRI can provide an objective and precise means to measure the muscle mass. This study is investigating the muscle enlargement seen in calves and tongues of patients affected by Becker muscular dystrophy and LGMD2I.
Enrollment is closed
– Denmark
Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies
In this study, people with DMA, BMD, and LGMD2I will be given Coenzyme Q10 (a nutritional supplement) or lisinopril (a drug) to see if it lowers the risk of heart problems compared to people who receive enhanced standard care without being given a drug or nutritional supplement.
