RayaldyTM – Significant Commercial Opportunity

Low serum 25D and high plasma PTH are prevalent in CKD Stage 3-4 patients o 8.0 million CKD Stage 3-4 patients in the U.S. U.S. has 4.0 million patients with low serum 25D and high plasma PTH Existing treatments are not effective or have significant safety issues (increased serum or urine calcium, leading to accumulation in kidney and additional damage) o RayaldyTM’s efficacy and safety compare favorably to both nutritional vitamin D and hormones in patients with Stage 3 or 4 CKD and will drive untreated patients to initiate treatment

hGH-CTP Phase II Positive Data

Analysis and Conclusions A single weekly injection of hGH-CTP can replace 7 daily injections of commercially available GH

Identified kick-start dosing for Phase III trial

Post-Phase II hGH-CTP Pilot Study Supports two hGH-CTP Injections Per Month Very Good safety and tolerability profile Only 50-65% of the cumulative daily GH dosing was required to maintain the majority of the patients within the normal range of IGF-1 Estimated COG 50-75% of commercially available GH

15

hGH-CTP Phase II and III Pediatric GHD Phase II trial (ongoing)

40-50 patients

4 cohorts; 3 receiving once weekly hGH-CTP at different doses, one control daily commercial

12 months efficacy and safety

Key outcome: Height velocity Adult Pivotal Phase III trial (initiated June 2013)

189 patients, estimated $20 million study

6 months efficacy and 6 months safety

Key outcome: Improvement in truncal fat

Confirmed by FDA as pivotal, planned for BLA submission in 2015 Received U.S. orphan drug status for children and adults First ever to receive E.U. orphan drug status for children and adults

Next Generation Prostate Cancer Testing – 4KScoreTM

The 4KScoreTM address a critical unmet need in Prostate Cancer care:

Current screening (based on PSA) leads to over-biopsy and over-treatment o PSA lacks predictive accuracy in the “grey zone” (3-10ng/mL) due to false positives (up to 75%)(1) o >1 million annual biopsies in the US, 750,000 are negative(2) o 4.2% of biopsies result in a complication that require an inpatient admission(3) 4KscoreTM provides prostate cancer risk assessment based four blood based biomarkers:

Total PSA (tPSA) o Free PSA (fPSA) o Intact PSA (iPSA) – the subset of free PSA with a preserved bond at Lys145-Lys146 o Human kallikrein 2 (hK-2) – also known as kallikrein-related peptidase 2 Validated across multiple patient cohorts predict cancer before biopsy o Retrospective tests in over 10,000 patients o Shows >80% accuracy in predicting prostate cancer o Can eliminate 50% of prostate biopsies

OPKO 4KScoreTM strategy Laboratory Developed Test in the US with a planned Q4 2013 introduction o $300 million market size as a new lab test before the first biopsy FDA-cleared point-of-care test on the Claros-1 System in 4-5 years o Will compete as an alternative to total PSA alone in the US $1B PSA market
