TEL AVIV, Israel, March 30, 2015 (GLOBE NEWSWIRE) — BioBlast Pharma Ltd. (ORPN), a clinical-stage, orphan disease-focused biotechnology company announced today positive in vivo proof-of-concept results for Cabaletta for Spinocerebellar Ataxia Type 3 (also known as SCA3 or Machado Joseph disease). Results were presented at the International Ataxia Research Conference held in Windsor UK, March 25-28, 2015.”
Cabaletta was tested in two different animal models of the disease:
- In a transfected mouse model, Cabaletta demonstrated efficacy in reducing the pathological cellular aggregates that are the root cause of the extensive nerve damage characteristic of SCA3. In a series of experiments, Cabaletta reduced the protein aggregations that are potentially toxic to neural cells, and reduced the biomarkers indicative of ubiquitin-imminent cell death. Immunohistochemistry studies corroborated this effect by demonstrating prevention of Darpp-32 loss in treated animal cells, a sensitive biomarker of neural damage.
- In a transgenic mouse model, treatment with Cabaletta was effective in preventing and preserving neural functions in multiple tests including the Rotarod and swimming tests.
Colin Foster, BioBlast’s President and CEO commented: “Our in vivo proof-of-concept studies demonstrate Cabaletta’s efficacy in reducing Ataxin3 aggregates, reducing neural markers for neural damage and preventing typical phenotypic deterioration in animal models. As a whole, this is powerful support for our ongoing SCA3 Phase 2 clinical trial program underway in Israel. We anticipate expanding the number of SCA3 clinical study centers later this year.
“There are approximately two dozen diseases that Cabaletta may address, given a common disease-causing mechanism related to intracellular and intranuclear protein aggregation. With Cabaletta, we have previously reported on our ongoing oculopharyngeal muscular dystrophy (OPMD) Phase 2/3 multicenter clinical trial and our preclinical work in spino bulbar muscular atrophy. Today, given the SCA3 proof-of-concept results, we share the fervent hopes of the many SCA3 patients waiting anxiously for a treatment for this devastating disease.”
Cabaletta is BioBlast’s proprietary intravenous (IV) solution of trehalose, a disaccharide, known for its capabilities in stabilizing intracellular and intranuclear proteins and enhancing autophagy.
About Spinocerebellar Ataxia Type 3 (SCA3 or Machado Joseph Disease)
SCA3, also known as Machado Joseph disease, is the most common among the cerebellar ataxias, which are a group of genetic diseases that are characterized by gait and movement disorders memory deficits, spasticity, difficulty with speech and swallowing, weakness in arms and other muscular anomalies. Symptoms can begin in early adolescence and get worse over time. Eventually SCA3 leads to paralysis and severe disability. The disease typically appears in the third or fourth decades of life and is associated with early death, on average within 15-20 years of diagnosis. There is currently no approved treatment for the disease.
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.
