DUBLIN, March 18, 2014 (GLOBE NEWSWIRE) -- Prothena Corporation plc (Nasdaq:PRTA), a clinical stage biotechnology company focused on the discovery, development and commercialization of novel antibodies for the potential treatment of diseases that involve protein misfolding or cell adhesion, announced today that an abstract (Abstract #PB-48) reviewing interim clinical data from its ongoing Phase 1 study of NEOD001 in patients with immunoglobulin light chain (AL) amyloidosis and persistent organ dysfunction will be presented at the XIV International Symposium on Amyloidosis (ISA) in Indianapolis, Indiana.
Data in the abstract was current as of January 7, 2014. The poster presentation will include data from the ongoing Phase 1 study as of late March.
Prothena is developing NEOD001, a humanized novel monoclonal antibody designed to neutralize and clear soluble and insoluble amyloid aggregates in patients with AL. NEOD001 is being studied in an ongoing Phase 1 study.
The abstract accepted for poster presentation is as follows:
(Abstract #PB-48) Preliminary cardiac biomarker responses demonstrated in an ongoing phase 1 study of NEOD001 in patients with AL amyloidosis and persistent organ dysfunction
- Presenter: Dr. Michaela Liedtke, Stanford Cancer Institute, Stanford, California
- Date: Tuesday, April 29
NEOD001 is a humanized monoclonal antibody that specifically targets the amyloid that accumulates in both AL and AA forms of amyloidosis. NEOD001 was granted orphan drug designation for the treatment of AL and AA amyloidosis by the U.S. Food and Drug Administration in 2012 and for the treatment of AL amyloidosis by the European Medicines Agency in 2013. The ongoing multi-center Phase 1 clinical trial is evaluating the safety, tolerability, pharmacokinetics and immunogenicity of NEOD001 in patients with AL amyloidosis and persistent organ dysfunction. The study is designed to define a maximally tolerated dose and/or recommended dose(s) for Phase 2/3. The study is also evaluating exploratory biomarkers for cardiac, renal and hepatic function.

About AL Amyloidosis
Systemic amyloidoses are a complex group of diseases caused by tissue deposition of misfolded proteins that result in progressive organ damage. The most common type, AL amyloidosis or primary amyloidosis, involves a hematological disorder caused by plasma cells that produce misfolded AL protein resulting in deposits of abnormal AL protein (amyloid) in the tissues and organs of individuals with this disease. There are no currently approved treatments for AL amyloidosis that directly target potentially toxic forms of the AL protein. AL amyloidosis is a rare disorder and it is estimated that about 15,000 patients in the U.S. and Europe suffer from AL amyloidosis. 1,200 to 3,200 new cases of AL amyloidosis are reported each year in the United States. Both the causes and origins of AL amyloidosis remain poorly understood.
Prothena Corporation plc is a clinical stage biotechnology company focused on the discovery, development and commercialization of novel antibodies for the potential treatment of diseases that involve protein misfolding or cell adhesion. These potential therapies have a number of indications, including AL and AA forms of amyloidosis (NEOD001), Parkinson's disease and related synucleinopathies (PRX002), and novel cell adhesion targets involved in inflammatory diseases and metastatic cancers (PRX003).
