BioBlast Pharma Announces Granting Of Fast Track Designation By The FDA For Cabaletta In Oculopharyngeal Muscular Dystrophy (OPMD)

TEL AVIV, Israel, April 9, 2015 (GLOBE NEWSWIRE) -- BioBlast Pharma Ltd. (Nasdaq:ORPN), a clinical-stage, orphan disease-focused biotechnology company announced today that the United States Food and Drug Administration (FDA) has granted Fast Track designation to Cabaletta for the treatment of patients with Oculopharyngeal Muscular Dystrophy (OPMD).

Cabaletta is being developed to treat OPMD, a rare and debilitating muscular dystrophy for which there is no cure or approved therapy. BioBlast is currently conducting a Phase 2/3 clinical study for OPMD and recently announced the granting of an IND, enabling the opening of a US clinical center in addition to the two ongoing clinical sites in Israel and Canada.

Established under the FDA Modernization Act of 1997, the Fast Track program is designed to facilitate the development and review of drugs intended to treat serious conditions and fill an unmet medical need. A drug development program with Fast Track designation is afforded greater access to the FDA for the purpose of expediting the drug's development, review, and potential approval.

"We believe that the Fast Track designation represents an important recognition by the FDA of Cabaletta's potential to address a significant unmet need in the treatment of OPMD patients," stated Colin Foster, BioBlast's President and Chief Executive Officer. "We will continue to work closely with the FDA with the goal of bringing Cabaletta to OPMD patients as quickly as possible," he added.

About Cabaletta

Cabaletta is BioBlast's proprietary intravenous (IV) solution of trehalose, a disaccharide, which has been shown to prevent pathological aggregation of proteins within cells in several diseases associated with abnormal cellular-protein aggregation as well as acting as an autophagy enhancer. Cabaletta has been documented as demonstrating significant efficacy in preclinical animal models of OPMD and other PolyA/PolyQ diseases.

About OPMD

OPMD is an inherited myopathy characterized by dysphagia (difficulty in swallowing) and the loss of muscle strength and weakness in multiple parts of the body. As the dysphagia becomes more severe, patients become malnourished, lose significant weight, become dehydrated and suffer from repeated incidents of aspiration pneumonia. Dehydration and aspiration pneumonia are often the cause of death. The disease is caused by a genetic mutation responsible for the creation of a mutant unstable protein (PABPN1) that aggregates within patient's muscle cells.

About BioBlast

BioBlast Pharma is a clinical-stage biotechnology company committed to developing clinically meaningful therapies for patients with rare and ultra-rare genetic diseases. The company has a diverse portfolio of product candidates with the potential to address unmet medical needs for incurable genetic orphan diseases.

The BioBlast platforms are based on deep understanding of the disease-causing biological processes, and potentially offer solutions for several diseases that share the same biological pathology.
