BioBlast Pharma Receives Orphan Drug Designation From the European Commission for Cabaletta for the Treatment of Oculopharyngeal Muscular Dystrophy

TEL AVIV, Israel, June 25, 2015 (GLOBE NEWSWIRE) -- BioBlast Pharma Ltd. (Nasdaq:ORPN), a clinical-stage orphan disease-focused biotechnology company, announced today that it has been granted Orphan Drug Designation by the European Commission for Cabaletta for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD).

BioBlast is starting a double-blind, placebo-controlled Phase 3 pivotal study across multiple clinical centers in the US and Canada in OPMD. The company recently announced positive clinical signals observed in its ongoing HOPEMD study.

Cabaletta is a chemical chaperone that has been shown to prevent pathological aggregation of proteins within cells in several diseases associated with abnormal cellular-protein aggregation, including cell and animal models of Spinocerebellar Ataxia and other PolyA/PolyQ diseases, in addition to OPMD.

"This Orphan Drug Designation lays the foundation for what we believe are very favorable conditions to address the needs of the many patients suffering from OPMD in Europe. It is yet another step in BioBlast's efforts to create and capture value from our research and clinical work," stated Colin Foster, President and Chief Executive Officer of BioBlast, who also noted that BioBlast has received Orphan Drug Designation for Cabaletta in OPMD from the FDA in the U.S.

About Orphan Drug Designation

Orphan Drug Designation by the European Commission provides regulatory and financial incentives for companies to develop and market therapies that treat a life-threatening or chronically debilitating condition affecting no more than five in 10,000 persons in the European Union (EU), and where no satisfactory treatment is available. In addition to a 10-year period of marketing exclusivity in the EU after product approval, orphan drug designation provides incentives for companies seeking protocol assistance from the EMA during the product development phase, and direct access to the centralized authorization procedure.

About Oculopharyngeal Muscular Dystrophy (OPMD)

OPMD is a rare inherited myopathy characterized by dysphagia (difficulty in swallowing), the loss of muscle strength, and weakness in multiple parts of the body. Patients typically suffer from severe dysphagia, ptosis (eye lid drooping), tongue atrophy, proximal lower limb weakness, dysphonia (altered and weak voice), limitation in looking upward, facial muscle weakness and proximal upper limb weakness. The disease is most often diagnosed in the fifth-sixth decade of life and progresses throughout the patient's life. As the dysphagia becomes more severe, patients become malnourished, lose significant weight, become dehydrated and suffer from repeated incidents of aspiration pneumonia. These last two are often the cause of death.

There is no medical treatment or, to our knowledge, potential cure for OPMD. Current therapeutic strategies are confined to surgical interventions that have limited efficacy and need to be repeated.
