BioBlast Pharma to Present Final HOPEMD Phase 2 Clinical Study Results of Trehalose in Oculopharyngeal Muscular Dystrophy at the American Academy of Neurology (AAN) 2016 Annual Meeting


NEW HAVEN, Conn., April 14, 2016 (GLOBE NEWSWIRE) -- BioBlast Pharma Ltd. (Nasdaq: ORPN), a clinical-stage, orphan disease-focused biotechnology company, will present previously announced positive final results from its HOPEMD Phase 2 six-month open-label clinical study in patients with oculopharyngeal muscular dystrophy (OPMD) at the 2016 American Academy of Neurology (AAN) Annual Meeting, being held in Vancouver, Canada April 15-21.  OPMD is a rare progressive muscle-wasting disease characterized by swallowing difficulties (dysphagia), leading to the risk of aspiration of food into the lungs, weight loss, and generalized progressive muscle weakness.

Twenty-four week results from the HOPEMD Phase 2 open-label study were announced by BioBlast on March 16th, 2016. Trehalose 90mg/mL IV solution was observed to be safe and well-tolerated with no drug-related serious adverse events.  Improvements versus baseline were observed in multiple secondary efficacy endpoints related to dysphagia and muscle strength and function.

About Trehalose 90mg/mL IV Solution
Trehalose 90mg/mL IV solution is a chemical chaperone that protects against pathological processes in cells.  It has been shown to reduce pathological aggregation of proteins within cells in several diseases associated with abnormal cellular-protein aggregation as well as acting as an autophagy enhancer.  Trehalose 90mg/mL IV solution has been documented as demonstrating significant promise in preclinical animal models of OPMD and other PolyA/PolyQ diseases.

In OPMD, trehalose 90mg/mL IV solution is being developed to prevent the aggregation of the pathological protein (PABPN1) in muscle cells, the hallmark of the disease, by stabilizing the protein, reducing the formation of protein aggregations, and promoting their clearance from cells through autophagy, thus preventing muscle cell death.

About Oculopharyngeal Muscular Dystrophy (OPMD)
OPMD is an inherited myopathy characterized by dysphagia (difficulty in swallowing), eyelid drooping (ptosis), the loss of muscle strength, and weakness in multiple muscles of the body.  Symptoms generally appear in mid-life and get worse over time.  As the dysphagia becomes more severe, patients become malnourished, lose significant weight, and may suffer from repeated incidents of aspiration pneumonia.  Aspiration pneumonia and severe emaciation may result in death.  The disease is caused by a genetic mutation responsible for the creation of a mutant protein (PABPN1) with an expanded polyalanine domain that aggregates within patient muscle cells.  There is currently no approved pharmacologic treatment for OPMD.
