Data From Phase II Trial of Prolor Biotech's Long-acting Human Growth Hormone Presented at Endo 2012

HOUSTON and NES-ZIONA, Israel, June 26, 2012 /PRNewswire/ -- PROLOR Biotech, Inc. (NYSE MKT: PBTH) today reported that researchers at ENDO 2012 presented data from the company's Phase II trial of its long acting human growth hormone, hGH-CTP, in growth hormone deficient adults.  The data, which were previously reported by the company, confirm that hGH-CTP has the potential to be administered once weekly to adults with growth hormone deficiency and that it appears to be safe and well tolerated.  The hGH-CTP data were discussed in an oral presentation at ENDO 2012, the 94^th Annual Meeting and Expo of the Endocrine Society, which is being held in Houston Texas June 23-26, 2012.

"ENDO 2012 represents a great opportunity to share the encouraging data we have reported from our completed Phase II trial of hGH-CTP with leading endocrinologists from North America and around the world," noted Dr. Abraham Havron, CEO of PROLOR Biotech.  "These data further confirm the potential of our long acting version of human growth hormone to be administered once-weekly, in contrast to the daily injections currently required.  We believe that informing the broader endocrinology community about our progress with hGH-CTP is timely as we continue to enroll subjects in our Phase II trial in growth hormone deficient children and prepare to initiate a Phase III trial in growth hormone deficient adults, expected later this year."

The data presented at ENDO 2012 included results from the main component of the Phase II trial, which administered hGH-CTP to growth hormone deficient adults for four weeks, as well as top-line results from a four-month treatment extension study of hGH-CTP in a similar population.  As reported last month, these data reaffirm the company's prior Phase II findings showing that a single weekly injection of hGH-CTP has the potential to replace seven consecutive daily injections of currently marketed human growth hormone, and they further validate the dosing regimen for the company's planned Phase III trial. 

The study, Once-Weekly, CTP-Modified hGH (MOD-4023) Is Effective in Growth Hormone Deficient Adults: A Phase II Dose and Frequency Finding Study, was discussed in an oral presentation on June 25, 2012 by clinical investigators who oversaw the Phase II trial.  For more information on ENDO 2012, visit www.endo-society.org/endo.
