hGH-CTP is PROLOR's proprietary long-acting version of human growth hormone. hGH is used for the long-term treatment of children and adults with growth failure due to inadequate secretion of endogenous growth hormone. It is also sometimes used to counter involuntary weight loss and certain physical manifestations of aging. Patients currently using hGH must inject the drug between two and seven times each week. In contrast, hGH-CTP is expected to require only weekly or bi-monthly injections. In 2007 the annual market for hGH was estimated at $2.5 billion.
PROLOR's CTP technology is based on an amino acid sequence that occurs naturally in humans, the carboxyl terminal peptide. When attached to a therapeutic protein, CTP extends the time that the protein is active in the body. The potential utility of the technology has been demonstrated by Schering-Plough, which in 2009 announced successful data from its Phase III ENGAGE trial demonstrating that women receiving a single injection of the fertility drug FSH-CTP achieved the same pregnancy rates as women receiving seven consecutive daily injections of commercial FSH. This 1,509 patient trial formed the basis for a Marketing Authorization Application by Schering-Plough that is currently under review by the European Medicines Agency. PROLOR is using the same CTP technology to extend the duration of action of human growth hormone and other therapeutic proteins. It has an exclusive license from Washington University in St. Louis to the CTP technology for use with all therapeutic proteins except for the four fertility hormones licensed to Schering-Plough.
