6 Clinical Trials for Various Conditions
HIBM is a severe progressive myopathy that typically presents in early adulthood as weakness in the distal muscles of the lower extremities and progresses proximally, leading to a loss of muscle strength and function, and ultimately a wheelchair-bound state. The rate of progression is gradual and variable over the course of 10-20 years or longer. There is a need to better understand the disease-specific features of HIBM to heighten disease awareness; facilitate early diagnosis; identify patients; expand knowledge of the clinical presentation, progression and variation of the disease; identify and validate biomarkers and other efficacy measures; inform on the design and interpretation of clinical studies of investigational products; and eventually to optimize patient management.
GNE myopathy is a rare genetic muscle disease characterized by progressive muscle atrophy and weakness. The disease is caused by mutations in the gene that encodes the enzyme that initiates and regulates N-acetylneuraminic acid (Neu5Ac) biosynthesis and glycan sialylation. Currently, there is no therapy available for this disease. N-Acetylmannosamine (ManNAc), an orphan drug in development for GNE myopathy, is an uncharged monosaccharide and the first committed precursor in Neu5Ac biosynthesis. In this randomized, double-blind, placebo-controlled trial the efficacy and long-term safety of ManNAc will be evaluated in subjects with GNE myopathy.
GNE myopathy or hereditary inclusion body myopathy (HIBM) is a severe progressive metabolic myopathy caused by a defect in the biosynthetic pathway for sialic acid (SA).
The objective of this study is to evaluate the long-term safety and efficacy of Ace-ER treatment in subjects with GNEM.
The primary objective of this Phase 2 study is to evaluate the safety of open-label 6 g/day Ace-ER in GNEM participants with severe ambulatory impairment.
The primary objective of this study is to evaluate the effect of 6 g/day aceneuramic acid extended-release (Ace-ER) treatment of participants with GNEM on upper extremity muscle strength (upper extremity composite \[UEC\] score) as measured by dynamometry.
