CARMIEL, Israel, Nov. 09, 2016 (GLOBE NEWSWIRE) -- Protalix BioTherapeutics, Inc. (NYSE MKT:PLX) (TASE:PLX) today announced financial results for the fiscal quarter ended September 30, 2016 and provided a business update.

“We are very excited by the progress made with our product candidates,” said Moshe Manor, Protalix’s President and Chief Executive Officer.  “We are currently enrolling patients in seven sites globally for our phase III clinical trial of PRX-102 for the treatment of Fabry disease, and we are finalizing enrollment in our phase II clinical trial of AIR DNase^TM (PRX-110) for the treatment of Cystic Fibrosis (CF).”

Financial Results for the Quarter Ended September 30, 2016

• Net loss for the quarter was $7.3 million, or $0.07 per share, for the three months ended September 30, 2016, an increase of $3.5 million from $3.8 million, or $0.04 per share, for the same period in 2015.  The increase is primarily the result of the initiation during 2016 of both our phase III clinical trial of Fabry disease and our phase II clinical trial of CF. 
• Total operating expenses were $7.1 million for the three months ended September 30, 2016 compared to $6.1 million for three months ended September 30, 2015.
• Cash and cash equivalents as of September 30, 2016 were $51.3 million, which provides the Company with capital into 2018.

Recent Company Highlights and Business Update

• First patient was enrolled in the Company’s phase III clinical trial of PRX-102 for the treatment of Fabry disease, with approximately 10 patients in the evaluation or screening process across seven sites.
