OPKO To Present 18-24 Month Clinical Data on its Long-acting Human Growth Hormone (hGH-CTP) from Open Label Extension (OLE) Phase 2 Pediatric Growth Hormone Deficiency Clinical Study in Oral Presentation at ENDO 2016

MIAMI--(BUSINESS WIRE)-- OPKO Health, Inc. (NYSE:OPK) today announced it will present 18-24 month clinical data from its ongoing open label extension study for hGH-CTP in an oral presentation at the Endocrine Society’s 98^th Annual Meeting to be held April 1-4, 2016, in Boston, MA.

The open label extension study is a continuation of our phase 2 one-year dose-finding study in which 53 naïve growth hormone deficient children received one of three doses of hGH-CTP once weekly (0.25, 0.48 and 0.66 mg/kg/week ) or daily Genotropin® as a comparator arm (34 µg/kg/day ). The published twelve-month data from the phase 2 study confirmed comparable response of hGH-CTP to daily Genotropin® as reflected by the twelve-month safety, efficacy and pharmacodynamic profile. Patients were rolled into the open label extension portion of the study while the daily arm patients were randomized to one of the hGH-CTP doses. For more information on the phase 2 study, please refer to https://clinicaltrials.gov/ct2/show/NCT01592500.

The oral presentation is scheduled for Sunday, April 3, 2016 at 11:45 AM - 1:15 PM ET, Oral Session Number: OR31-6.

Based on the promising phase 2 clinical data, OPKO confirms its plan to initiate a global pivotal phase 3 study in pre-pubertal growth hormone-deficient children later this year evaluating a weekly single dose of hGH-CTP versus daily injections of growth hormone. OPKO has a world-wide collaboration agreement with Pfizer Inc. for the development and commercialization of hGH-CTP.

OPKO poster presentations on hGH-CTP include the following:

In addition, the following poster presentations will include non-clinical data characterizing Oxyntomodulin (MOD-6031), a novel long acting dual GLP-1/Glucagon agonist for the induction of weight management.

Earlier this month, OPKO announced dosing of the first subject in a phase 1 single dose escalation study evaluating the safety and pharmacokinetics of a long-acting Oxyntomodulin in healthy, overweight or obese subjects. The study is intended to enroll 40 subjects in Israel.

About hGH-CTP

hGH-CTP is a novel, long-acting recombinant human growth hormone analog being developed by OPKO for the treatment of children with growth failure due to inadequate endogenous growth hormone secretion, and adults with growth hormone deficiency (GHD) of either childhood or adult-onset etiology. hGH-CTP is intended to reduce the burden of daily injection therapy.

OPKO's proprietary technology enables elongation of a therapeutic protein's half-life without the use of polymers, encapsulation techniques, or nanoparticles. This technology is based on a natural peptide, the C-terminal peptide (CTP) of the beta chain of human chorionic gonadotropin (hCG). hGH-CTP has been granted orphan drug designation in the U.S. and Europe for both adults and children with growth hormone deficiency.

About Oxyntomodulin

Oxyntomodulin is a peptide hormone that acts as a dual GLP-1/Glucagon receptor agonist, with the potential to promote weight loss while improving glycemic control. Oxyntomodulin has been shown to increase energy expenditure, while reducing food intake and body weight, although its clinical utility is limited by its short circulating half-life. OPKO's MOD-6031 has been designed, using a proprietary bi-functional hydrolysable linker, as a long-acting version of Oxyntomodulin for the treatment of Type II diabetes and obesity, and is intended to reduce the required dosage frequency by prolonging the half-life, while improving the hormone's pharmacokinetics and pharmacodynamics. A MOD-6031 phase 1 study was recently initiated.
