Protalix BioTherapeutics Announces New Strategy for Accelerated Growth

Prioritizing Pipeline Candidates to Focus on Bio-better Products with a Clear Competitive Advantage

CARMIEL, Israel, January 5, 2015 /GlobeNewswire /Protalix BioTherapeutics, Inc. (NYSE MKT:PLX, TASE:PLX), announced today the Company’s newly implemented strategy for accelerated growth. The strategy centers around prioritizing existing and new pipeline candidates to focus on bio-better products with potentially clinically superior profiles that offer a clear competitive advantage. The following highlights the details of the strategic plan.

PRX-102 for Fabry disease

PRX-102 is designed to be an improved enzyme replacement therapy product for Fabry disease given its potential for clinically superior outcomes and enhanced safety when compared to currently marketed enzyme replacement therapies. The product remains a key focus for the Company and will aggressively be pushed through clinical development. Interim efficacy and safety data from the Company’s ongoing Phase I/II trial will be presented during Protalix’s corporate presentation at the JP Morgan Healthcare Conference on January 15, 2015.

Oral Anti-TNF (PRX-106) for Inflammatory Bowel Disease

Oral Anti-TNF represents a novel mode of administering a recombinant anti-TNF protein. The Company plans to initiate clinical efficacy trials of Oral Anti-TNF for the treatment of Inflammatory Bowel Disease (IBD) in a non-IND setting during 2015. Upon reviewing the proof of concept (POC) data, expected in early 2016, the Company intends to collaborate with a well-suited partner for further development.

AIR DNase (PRX-110) for Cystic Fibrosis

AIR DNase has an actin inhibition resistance that is designed to improve lung function and lower the incidence of recurrent infections by enhancing the enzyme’s efficacy in patients sputa. The product has demonstrated improved disease parameters in animal models and human sputum testing when compared to the currently marketed product. The Company plans to initiate clinical efficacy trials of AIR DNase for the treatment of Cystic Fibrosis (CF) in a non-IND setting during 2015. Upon reviewing the results of the trial, expected in early 2016, the Company intends to collaborate with a well-suited partner for further development.

Oral GCD (PRX-112) for Gaucher Disease

Oral GCD represents a novel mode of administrating taliglucerase alfa, the Company’s approved enzyme replacement therapy for Gaucher disease. The initial clinical data generated for this compound in pre-clinical and Phase I trials is promising. In 2015, Protalix will focus on improving the drug’s formulation and delivery in order to transform it into a commercially viable product.

Potential Pipeline Candidates

Protalix aims to expand the Company’s pipeline by leveraging the advantages of the ProCellEx® proprietary protein expression technology. The focus will be on biologics with improved clinical profiles than the currently marketed proteins for these indications. Biosimilars will not be a focus for the Company, and will only be considered in the case of proteins that are highly difficult to express or that represent opportunities for early market entry arising from Protalix’ plant cell based intellectual property advantages.

Elelyso™ for Gaucher Disease

The Company anticipates continuing to increase market share in Israel. Additionally, management intends to continue to work closely with its collaboration partner, Pfizer Inc., and with the Brazilian government to increase sales globally.

“We are very excited with our new path forward as there are a number of key value creating milestones that have the potential to significantly increase shareholder value,” commented Mr. Moshe Manor, President and CEO of Protalix. “We will have three molecules in clinical trials in 2015 which will all report efficacy data over the next 15 months, and collectively target markets over $5 billion. We have a strong cash position of approximately $54 million which will provide the financial resources necessary to implement our strategic objectives.”
