CARMIEL, Israel, Jan. 13, 2014 (GLOBE NEWSWIRE) -- Protalix BioTherapeutics, Inc. (NYSE MKT:PLX) (TASE:PLX), announced today that Dr. David Aviezer, the Company's President and Chief Executive Officer, will discuss the Company's corporate objectives and key milestones in a presentation at the 32nd Annual J.P.

"In 2014, Protalix anticipates achieving a number of milestones on both the commercial and clinical front that have the potential to add significant value," commented Dr. Aviezer. "We expect to see sales of ELELYSO® (taliglucerase alfa) increase across all approved and launched territories, primarily in the United States, Israel, Brazil, Chile and Mexico.  Additionally, we expect ELELYSO to be approved in Canada, Australia and Argentina.  On the clinical front, we plan to report data from two key clinical programs, Oral GCD for the treatment of Gaucher disease and PRX-102 for the treatment of Fabry disease, and to initiate clinical trials for our oral antiTNF and Dnase compounds."

2013 Highlights

ELELYSO/UPLYSO highlights

• Approved in Brazil, Mexico and Chile; the drug was already approved in the United States, Israel and Uruguay. 
   
• In Israel, since the addition of ELELYSO to Israel's national healthcare reimbursement basket in early 2013, ELELYSO has become the drug of choice for naïve adult Gaucher patients. Substantially all newly treated adult Gaucher patients in Israel during 2013 received our drug.
   
• In Chile, during the fourth quarter of 2013, all adult Gaucher patients previously treated with other enzyme replacement therapies were successfully switched to UPLYSO/ELELYSO. 
   
• An application for a pediatric indication of ELELYSO has been submitted to the U.S. Food and Drug Administration. 
   
• The Company entered into a supply and technology transfer agreement in Brazil for UPLYSO, whereby Fiocruz committed to purchase at least approximately $40 million worth of the drug during the first two years of the agreement and at least approximately $40 million worth of the drug each subsequent year under the agreement.  The first shipment of the drug to Brazil under the agreement with Fiocruz has just been made. In addition, in accordance with the technology transfer agreement, Fiocruz has initiated the regulatory process with ANVISA for the registration of the drug, which is another step in progressing the agreement contingent to the progression of the commercial aspects.  Fiocruz has notified the Company that it has purchased a lot in the Brazilian state of Ciera where it plans to erect its UPLYSO manufacturing site in the future.

Clinical highlights

• The Company reported positive top-line phase I clinical trial results for Oral GCD in Gaucher patients. 
   
• The Company disclosed three new compounds in development: Oral PRX-106, an oral formulation of antiTNF alpha for the treatment of immune and inflammatory mediated disorders; PRX-110 for the treatment of Cystic Fibrosis; and PRX-107, an alpha1-antitrypsin for the treatment of emphysema.
   
• The U.S. Patent and Trademark Office granted the Company a new patent entitled "Human lysosomal proteins from plant cell culture" (U.S. patent 8449876). This patent relates to plant cells expressing our GCD composition for oral treatment of Gaucher disease.

2014 Commercial and Clinical Milestones

ELELYSO/UPLYSO Milestones

• In Israel, the Company anticipates continued growth, and that approximately 25% of adult Gaucher patients will be treated with ELELYSO.
   
• In Brazil, in accordance with the technology transfer and supply agreement, the Company expects that a total of approximately $39 million will be invoiced through July 31, 2015.
   
• The Company anticipates that its collaboration with Pfizer Inc. will continue to be profitable in 2014, with the Company's share in the collaboration to continually increase.  ELELYSO has recently been selected as the drug of choice for Gaucher patients by certain regional insurance providers in the United States, and similar agreements with certain other national and regional providers are currently being discussed. The Company is hopeful that some of these agreements will materialize during 2014; such agreements should contribute to further growth in the Company's share in the collaboration.
   
• Marketing approvals for ELELYSO/UPLYSO are currently pending in several countries, including Canada, Australia and Argentina. We are hoping to obtain approvals in 2014.

Clinical Milestones

• Report interim results from the Company's phase I/II clinical trial of PRX-102 in Fabry patients during the second half of 2014; full results during the first half of 2015.
   
• Report phase I clinical trial results for Oral GCD, including results from patients with low platelet counts, at the Lysosomal Storage Disease Network WORLD Symposium (LDN WORLD) in February 2014.
   
• Initiate next phase clinical trial of Oral GCD in the second half of 2014.
   
• Initiate phase I clinical trial of the Oral PRX-106 anti TNF for the oral treatment of autoimmune diseases in 2014.
   
• File investigational new drug application (IND) enabling the initiation of a phase I clinical trial of PRX-110 for the treatment of Cystic Fibrosis in 2014.
