MIAMI, Aug. 29, 2019 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ: OPK) today announced that the last patient has completed the final visit in the Company’s pivotal Phase 3 study evaluating the safety and efficacy of the once weekly somatrogon (hGH-CTP) for treatment of growth hormone deficiency in children. The study enrolled a total of 224 treatment naïve patients from 21 countries who were randomized 1:1 into two arms: once-weekly somatrogon vs. once-daily Genotropin® (somatropin). The primary endpoint of the trial is height velocity at 52 weeks. Secondary endpoints are safety and pharmacodynamic endpoints.  The clinical safety and efficacy data are currently in the process of being compiled and validated prior to data base lock. Top line results are expected to be announced in the fourth quarter of 2019.

Patients who completed the Phase 3 study had the option to enter an open label extension study to evaluate the long-term safety of somatrogon.  Approximately 95% of the patients switched into the open label extension study and receive somatrogon treatment.  

“We are pleased to report the completion of the somatrogon pivotal study, an important milestone in the development of once weekly somatrogon. Completion of this study brings us a step closer to potentially providing children with growth hormone deficiency a once weekly treatment," stated Phillip Frost, M.D., Chairman and Chief Executive Officer of OPKO.  “We believe that a once weekly treatment could offer a convenient dosing regimen, which by reducing the number of injections could enhance a patient’s adherence to treatment and quality of life."

In 2014, Pfizer Inc. and OPKO entered into a worldwide agreement for the development and commercialization of somatrogon for the treatment of growth hormone deficiency. Under the agreement, OPKO is responsible for conducting the clinical program and Pfizer is responsible for registering and commercializing the product.
