• BioReference Laboratories increased COVID-19 testing nationwide:  During the second quarter, BioReference Laboratories (BRL) announced numerous partnerships and testing agreements with states, cities, professional sports associations and healthcare organizations, including the New York State Department of Health, New York City Health and Hospital Corporation and MagnaCare.  Further, BRL provided testing services for more than 500 drive-thru and retail testing sites around the country.  In July 2020, the Company announced that the Centers for Disease Control and Prevention (CDC) awarded BRL an Indefinite Delivery Indefinite Quantity contract to provide Commercial Surge Capacity Testing for COVID-19, under which BRL will perform antibody testing to determine COVID-19 seroprevalence and other testing with key demographic data for the next four months.
  
  BRL processed approximately 2.2 million COVID-19 molecular tests during the second quarter and currently has a capacity of more than 50,000 daily. Since late April, when BRL began offering COVID-19 serology testing to measure SARS-CoV-2 specific antibody levels, it has performed approximately 331,600 tests with a significantly greater capacity.
  
  
• Successful 4Kscore^® Medicare appeal for tests performed during 2019:  As previously announced, Novitas Solutions issued its final Local Coverage Determination for Medicare payments for the 4Kscore test with defined coverage criteria, effective December 30, 2019. The Company received a favorable Medicare appeal decision from Novitas for previously denied Medicare claims for 4Kscore tests performed in 2019.  The COVID-19 pandemic impacted utilization of 4Kscore during the second quarter as many urology practices were either closed or operating at reduced capacity.  More than 8,400 tests were performed during the quarter despite fewer patient visits and access to physicians. The volume of 4Kscore tests has been increasing in recent weeks with the gradual re-opening of the economy and patients resuming visits to their physicians.
  
  
• Positive somatrogon topline results reported from Japan pediatric Phase 3 efficacy and safety study:  In June, OPKO announced that its Japan Phase 3 clinical trial met its primary and secondary objectives, and demonstrated that the efficacy and safety of somatrogon administered once-weekly were comparable to GENOTROPIN^® (somatropin) administered once-daily as measured by annual height velocity after 12 months of treatment in treatment-naïve Japanese pre-pubertal children with growth hormone deficiency. The findings were consistent with the results previously reported from the Company's global Phase 3 study.
   
• Somatrogon abstracts presented at Endocrine Society's ENDO Online 2020:  Two abstracts regarding the somatrogon global Phase 3 trial were presented at ENDO Online 2020 by Cheri Deal, PhD, MD, FRCPC, Chief of Pediatric Endocrinology and Diabetes at CHU Sainte-Justine and Tenured Professor of Pediatrics at Université de Montréal, the Principal Investigator of the study.  The two abstracts, "Somatrogon Growth Hormone in the Treatment of Pediatric Growth Hormone Deficiency:  Results of the Pivotal Phase 3", and "Interpretation of Insulin-like Growth Factor (IGF-1) Levels Following Administration of Somatrogon (a long-acting Growth Hormone-hGH-CTP)," were published online in the April-May supplemental issue of the Journal of Endocrine Society. Dr. Deal's presentation included data demonstrating that somatrogon administered once weekly, met its endpoint of non-inferiority to daily GENOTROPIN^® (somatropin) in height velocity and height standard deviation score (SDS).  In addition, Dr. Deal presented new data demonstrating that over 95% of patients had mean IGF-1 SDS levels within the normal range. IGF-1 SDS is a biomarker to evaluate efficacy and safety of human growth hormone replacement therapy.
   
• Somatrogon global regulatory submissions:  The somatrogon Biologics License Application (BLA) submission in the U.S. is anticipated to occur in the fall of 2020.  In Europe, the Company's open-label study demonstrating benefit and compliance with reduced treatment burden will be completed this quarter, enabling Pfizer to submit for regulatory approval in Europe early next year. The somatrogon regulatory submission in Japan is expected during the first half of 2021.
   
• RAYALDEE total prescriptions reported by IQVIA increased 45% in the second quarter of 2020 compared with the second quarter of 2019:  Total prescriptions for the three months ended June 30, 2020 increased to approximately 18,400, compared to approximately 12,700 for the second quarter of 2019.  During the second quarter of 2020, demand for RAYALDEE remained strong but prescription growth was impacted by limited access to physician offices by both patients and OPKO's sales representatives. 
   
• RAYALDEE authorized for Phase 2 clinical trial in patients with mild-to-moderate COVID-19:  On June 1, 2020, OPKO announced that the U.S. Food and Drug Administration (FDA) authorized the Company to undertake a Phase 2 trial with RAYALDEE as a treatment for patients with mild-to moderate COVID-19.  The trial, entitled "A Randomized, Double-Blind Placebo-Controlled Study to Evaluate the Safety and Efficacy of RAYALDEE (calcifediol) Extended-release Capsules to Treat Symptomatic Patients Infected with SARS-CoV-2 (REsCue)," will enroll approximately 160 subjects, including many with stage 3 or 4 chronic kidney disease. The REsCue trial will have four weeks of treatment with RAYALDEE or placebo and two weeks of follow-up.  There are two primary efficacy endpoints:  time to resolution of COVID-19 symptoms; and consistent attainment of serum total 25-hydroxyvitamin D levels greater than or equal to 50 ng/mL during the last week of treatment. The trial is expected to begin enrolling subjects later this quarter.
