MIAMI -- May 20, 2014

OPKO Health, Inc. (NYSE: OPK), announced that it will present new clinical
data on its long-acting human growth hormone product (hGH-CTP) at the ICE/Endo
2014, the joint meeting of The Endocrine Society and The International
Congress of Endocrinology in Chicago on June 21^st-24^th.

OPKO Biologics (formerly PROLOR Biotech) scientists will present
pharmacokinetic and pharmacodynamic data from the company's advanced phase 2
trial of hGH-CTP in growth hormone deficient pediatric subjects. The data to
be presented include results from the company’s phase 2 trial, which is a one
year dose finding study administering hGH-CTP to growth hormone deficient
children once a week using daily hGH as a comparator arm. These data affirmed
that a single weekly injection of hGH-CTP has the potential to replace seven
consecutive daily injections of currently marketed hGH, further validating the
dosing regimen for the upcoming phase 3 trial. In addition, hGH-CTP
demonstrated a very good safety and tolerability profile in this ongoing
study, with no unexpected adverse events.

In addition, OPKO will hold a clinical workshop and present to
endocrinologists participating in the hGH-CTP clinical studies, top line six
month efficacy data from the phase 2 trial.
