PROLOR Biotech to Present Data on Its Long-Acting Clotting Factors at Leading International Scientific Conference

LIVERPOOL, England and NES-ZIONA, Israel, June 29, 2012 /PRNewswire/ -- PROLOR Biotech, Inc. (NYSE MKT: PBTH), today announced that PROLOR scientist Dr. Gili Hart will present data on the company's long-acting clotting factors in preclinical development for the treatment of hemophilia at the 58th Annual Meeting of the Science and Standardization Committee of the International Society on Thrombosis and Haemostasis (ISTH).  Dr. Hart's oral presentation will take place tomorrow, June 30, 2012, at the ISTH meeting in Liverpool, UK.

In her presentation, Dr. Hart will discuss data from preclinical studies of PROLOR's long-acting versions of Factor VIIa (Factor Vlla-CTP) and Factor lX (Factor IX-CTP).  Top-line results of these studies were previously reported by PROLOR.  The results showed that compared to commercially available Factor VIIa, hemophilic mice receiving Factor VIIa-CTP demonstrated a superior survival rate over a longer time period following a bleeding challenge, superior and longer-lasting generation of the pro-clotting enzyme thrombin, and significantly higher in vivo recovery, a pharmacokinetic measure of clotting activity.

Factor IX-CTP demonstrated significantly longer duration of clotting activity in a hemophilic mice model compared with commercially available Factor IX, and bleeding episodes were significantly shorter and less intense for the group treated with Factor IX-CTP.  In addition, none of the animals treated with Factor IX-CTP had any spontaneous re-occurring bleeding events, compared with a 50% incidence of re-bleeding events for the group treated with commercial Factor IX.

PROLOR CEO Dr. Abraham Havron commented, "The ISTH provides critical scientific guidance to researchers and clinicians working to improve the treatment of clotting and thrombotic disorders globally, and we are very pleased that our promising new approaches for managing hemophilia have been selected for presentation at this prestigious meeting."

Dr. Hart's presentation, "A clinically validated technology for elongating the half life of coagulation factors, enabling a prolonged haemostatic activity in hemophilic animal models," is scheduled at 12:10 pm BST on June 30, 2012.  The 58th Annual Meeting of the Science and Standardization Committee of the ISTH is being held June 27-30, 2012.  For more information, visit http://www.ssc2012.org/.

The results of clinical trials in humans may produce results that differ significantly from the results of clinical and other trials in animals. The results of early-stage trials may differ significantly from the results of more developed, later-stage trials. The development of any products using the CTP platform technology could also be affected by a number of other factors, including unexpected safety, efficacy or manufacturing issues, additional time requirements for data analyses and decision making, the impact of pharmaceutical industry regulation, the impact of competitive products and pricing and the impact of patents and other proprietary rights held by competitors and other third parties.  In addition to the risk factors described above, investors should consider the economic, competitive, governmental, technological and other factors discussed in PROLOR's filings with the Securities and Exchange Commission.  The forward-looking statements contained in this press release speak only as of the date the statements were made, and we do not undertake any obligation to update forward-looking statements, except as required under applicable law.
