OPKO Provides Update to Topline Data of Phase 3 Clinical Study of hGH-CTP in Growth Hormone Deficient Adults

MIAMI, June 15, 2017 -- OPKO Health, Inc. (NASDAQ:OPK) announces an update to the topline data analysis of the Phase 3, double-blind, placebo-controlled study of its investigational long-acting human growth hormone product (hGH-CTP) in adults with growth hormone deficiency (GHD). In December 2016 OPKO reported that the primary endpoint of change in trunk fat mass from baseline to 26 weeks did not demonstrate a statistical difference between the hGH-CTP treated group and placebo. At the time, one or more outliers were identified that may have affected the outcome on the primary endpoint.    

OPKO has now completed post-hoc sensitivity analyses to evaluate the influence of outliers on the primary endpoint results using multiple statistical approaches.  Analyses that excluded outliers showed a statistically significant difference between hGH-CTP and placebo on the change in trunk fat mass.  Additional analyses that did not exclude outliers showed mixed results. Post-hoc analyses do not carry the same weight of evidence as a pre-specified primary analysis.

“We are encouraged by the results of these analyses,” stated Phillip Frost, M.D., OPKO Chairman and Chief Executive Officer. 

OPKO has initiated a global Phase 3 trial, utilizing a multi-dose disposable pre-filled pen, to evaluate hGH-CTP in pediatric GHD patients. OPKO also plans to utilize this multi-dose pen for patients who continue in the open label extension phase of the adult Phase 3 and the pediatric Phase 2 GHD studies. In addition, preparation for the pivotal pediatric GHD trial in Japan is progressing and site selection is near completion.
