Release Details

CARMIEL, Israel, Aug. 10, 2015 (GLOBE NEWSWIRE) -- Protalix BioTherapeutics, Inc. (NYSE MKT:PLX) (TASE:PLX), today reported financial results for the second quarter of 2015.

"We recently reported positive Phase I results for PRX-106 (oral Anti-TNF), with exciting results showing biological activity in the gut and activation of regulatory T cells," said Moshe Manor, Protalix's President and Chief Executive Officer. "We look forward to selecting an indication and moving this program into a proof of concept trial around year-end. Additionally, we anticipate interim results for PRX-102 for the treatment of Fabry disease in September, including 6-month data for the 1mg/kg dose group and 12-month data for the 0.2mg/kg group. We also expect to initiate a proof of concept study for AIR DNase^TM in Cystic Fibrosis patients early next year."

Financial Results for the Period Ended June 30, 2015

• Net loss narrowed to $5.1 million, or $0.05 per share, for the three months ended June 30, 2015, down $1.0 million, or 17%, from $6.1 million, or $0.07 per share, for the same period in 2014.
   
• Total revenues for the three months ended June 30, 2015 were $3.8 million compared to $2.4 million in the same period in 2014. The increase resulted primarily from an increase of $1.3 million in sales in Brazil compared to the same period in 2014.
   
• Revenue from the Company's share of net income from the collaboration under the Pfizer agreement increased by $573,000, to $834,000 for the three months ended June 30, 2015 compared to $261,000 for the same period in 2014.
   
• Total worldwide sales of Elelyso^TM during the six months ended June 30, 2015 were $15.8 million, an increase of $2.7 million, or 21%, compared to worldwide sales of $13.1 million for the six months ended June 30, 2014.
   
• Cost of revenues was $4.4 million for the six months ended June 30, 2015 compared to $5.7 million for the same period in 2014. 
   
• Selling, general and administrative expenses decreased 24% to $4.0 million for the six months ended June 30, 2015 compared to $5.3 million for six months ended June 30, 2014. The decrease resulted primarily from a decrease of $1.0 million in salaries expenses, and the devaluation of the New Israeli Shekel against the U.S. Dollar during the period.
   
• Cash and cash equivalents as of June 30, 2015 were $43.2 million representing an average quarterly cash consumption of approximately $5.8 million, a $1.9 million decrease compared to the same period in 2014.

Second Quarter and Recent Clinical and Corporate Highlights

• The Company is actively discussing with Fundação Oswaldo Cruz ("Fiocruz") potential actions that Fiocruz may take to comply with its purchase obligations under the Tech Transfer and Supply agreement since, as of July 31, 2015, Fiocruz has not yet achieved its minimum purchase obligation thereunder.  The Company is, at this time, continuing to supply Uplyso^TM to Fiocruz under the agreement, and patients continue to be treated with Uplyso in Brazil, as approximately 10% of adult Gaucher patients in Brazil are currently treated with Uplyso. 
   
• Ex-vivo efficacy studies in Cystic Fibrosis patients' sputum DNase show greater efficiency of AIR DNase compared to Pulmozyme® by reducing sputum viscoelasticity and DNA content. Toxicology studies of AIR DNase are being concluded to support the initiation of a phase I clinical study in healthy volunteers during the next quarter followed by a proof of concept study in Cystic Fibrosis patients early next year.
   
• Phase I data for PRX-106 received in July demonstrate a favorable safety profile as well as biological activity in the gut and the activation of regulatory T cells.
   
• The Company has commenced upgrading its manufacturing facility to become a multiproduct facility and support the manufacturing of PRX-102, in addition to taliglucerase alfa in a commercial scale. The Company expects that the upgraded facility will be able to support the worldwide marketing needs of both products. Due to the Company's unique platform technology, the Company does not expect that these efforts will entail additional capital expenditures.
