PROLOR Biotech to Present Data on Its Long-Acting Human Growth Hormone at Pediatric Endocrinology Meeting

LEIPZIG, Germany and NES-ZIONA, Israel, Sept. 21, 2012 /PRNewswire/ -- PROLOR Biotech, Inc. (NYSE MKT: PBTH) today announced that data from the company's Phase II trial of hGH-CTP, its long acting human growth hormone, in growth hormone deficient adults will be presented at ESPE 2012, the 51st Annual Meeting of the European Society for Paediatric Endocrinology. 

The previously reported data confirmed that a single weekly injection of hGH-CTP has the potential to reduce the required dosing frequency of human growth hormone from the current standard of one injection per day to a single weekly injection.  In this trial, hGH-CTP demonstrated a good safety and tolerability profile.  In addition, the study showed that only 50-65% of the cumulative weekly dose of conventional human growth hormone was required for the majority of the patients to remain within the normal range of IGF-1, a key biomarker of growth hormone activity.  The safety profile of hGH-CTP in this trial was further enhanced by the finding that it did not cause excessive IGF-1 levels in patients, nor was any IGF-I accumulation observed.

The positive Phase II data in adults were instrumental in PROLOR's decision to proceed with a Phase II hGH-CTP trial in growth hormone deficient children that is currently enrolling patients.  The pediatric Phase II trial is a randomized, open-label, dose-finding study to evaluate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamic properties of hGH-CTP injected weekly in children with growth hormone deficiency.  The trial is comparing the 12-month growth velocity of children receiving hGH-CTP injected once weekly with those receiving commercially available hGH injected daily.

"Growth hormone replacement therapy may enable a growth hormone deficient child to reach a normal height, but it currently involves daily dosing that may total more than 3,000 injections before the child reaches the age of 18," said Dr. Abraham Havron, CEO of PROLOR.  "hGH-CTP has the potential to dramatically reduce this number, thereby making growth hormone therapy less burdensome and more feasible.  We welcome the opportunity to raise awareness of our progress with hGH-CTP at this meeting of pediatric endocrinology opinion leaders."

Poster P1-d3-296, Once-Weekly, CTP-Modified hGH (MOD-4023) Effectively Maintains IGF-1 Levels Within the Normal Range in Growth Hormone Deficient Adults, Supporting Initiation of Clinical Development in Children, will be presented during the September 22, 2012 poster session of ESPE 2012, which  is being held September 20-23, 2012 in Leipzig, Germany.  For more information, visit http://www.espe2012.org/.
