Thank you, Phil. Through the first quarter of 2017 also made important progress. And we are pleased with our U.S. launch of reality to treat secondary hyperparathyroidism or SHPT in patients with Stage 3 or 4 chronic kidney disease or CKD and vitamin D insufficiency. RAYALDEE is the only FDA approved product for this indication. We launched RAYALDEE in the U.S. at the end of November 2016 and have built a solid marketing and sales team of 50 professionals. Dr. Akhtar Ashfaq has recently joined OPKO as Senior Vice President, Clinical Research and Development and Medical Affairs of our Renal Division. Dr. Akhtar Ashfaq was previously with AstraZeneca where he served as Executive Director and Head of the CKD program within Global Medical Affairs. Before that he served as a Medical Director for Amgen. We are pursuing an aggressive marketing and sales effort as we continue to add new payers. Over the first quarter the number of physician prescribers for RAYALDEE is up eight-fold. The soon to be published KDIGO guideline for the treatment of chronic kidney disease, metabolic bone disease is expected to recommend against routine use of vitamin D receptor activators for VDRAs to treat SHPT in Stage 3 and 4 CKD highlight the unproven effectiveness of vitamin D supplementation. As these presently represent the only competitive products RAYALDEE used to be greatly enhanced. Moving forward we plan to leverage our investment in our RAYALDEE sales force and commercial infrastructure we will advance our clinical plans in a number of important programs. First is the final Phase 3 clinical study for Fermagate, a magnesium based calcium free phosphate binder for hyperphosphatemia in CKD patients on dialysis already shown to be safe and effective in treating hyperphosphatemia in Phase 2 and 3 trials. In preparation for the upcoming Phase 3 trial we are completing additional animal studies to confirm Fermagate ability to limit vascular calcification the leading cause of morbidity and mortality in CKD patients. Next is the Phase 2 clinical trial of a higher strength for RAYALDEE for hemodialysis patients between which we plan to adopt in collaboration with our partner Vifor Fresenius. This study should begin as soon as we reach agreement with FDA on trial design, we expect it later this year. In addition the Vifor Fresenius continues to advance its marketing applications for RAYALDEE in Europe, Canada and Mexico as a treatment for SHPT in Stage 3 and 4 CKD patients. We have other important product development programs underway. Let me start with an update on our long-acting human growth hormone product hGH-CTP partner for worldwide commercialization with Pfizer. Late last year we reported top line data for the multinational, multicenter Phase 3 study in 198 adults with hGH deficiency. The primary efficacy endpoint of that study was mean change in trunk fat mass. While we reported that the study did not meet its primary endpoint it did meet the secondary endpoint of IGF1 normalization with 97% hGH-CTP subjects versus only 6% of the placebo subjects achieving IGF1 at normalization. This biochemical marker indicates the activity of human growth hormone in this population. The safety profile of hGH-CTP in our study was consistent with that observed with patients treated with growth hormone injected daily. We continue to validate and conduct QA and QC analysis of the data from the Phase 3 study as part of their routine work to support the forthcoming BLA submission. This is a time consuming process given the large number of study sites and geographic footprint. Frankly more time consuming than we had anticipated. Completion of this work however is imminent. And upon completion we will carry out an official outlier sensitivity analysis of the data. Since the completion of the pivotal phases of Phase 3 adult hGH-CTP in August 2016. And Phase 2 pediatric hGH-CTP in July 2015. A significant number of patients have continued in the open label extension or OLE phases pending drug approval. Patients in the pediatric study are well into the third year of treatment with long-acting hGH-CTP. To-date over 18,000 doses of hGH-CTP have been administered to patients and no serious safety concerns have been reported. Plans to switch from delivery with a syringe to injector pens for the patients in the above mentioned OLE studies are progressing. And we expect all patients will be using the pen devices by early first half of next year. We are confident about the outcome of the adult growth hormone deficiency study and continue to expect to submit a BLA for FDA approval of hGH-CTP in adult by the end of this year. Moving on to our pediatric hGH-CTP program, we continue to enroll subjects in our global pivotal Phase 3 study in 220 pre-pivotal growth hormone deficient children, which is evaluating a single weekly dose of hGH-CTP versus daily injections of currently marketed growth hormone. We plan to begin our pediatric hGH-CTP registrations in Japan in the third quarter of this year. The pediatric segment represents approximately 80% of the market for treatment of hGH deficiency. I note that the primary efficacy endpoints for treating adult growth hormone deficient patients is reduction of trunk fat mass. This endpoint is quite different from the primary endpoint for treating pediatric growth hormone deficient patients, which assesses growth high velocity. Data from our pediatric hGH-CTP Phase 2 study affirmed that single weekly injections of our drug have the potential to replace daily injections of currently marketed growth hormone in pediatric patients. We are satisfied with the progress of these late stage programs, as we move toward commercialization. This is an area with a significant and growing market opportunity and we believe through our partnership with Pfizer, we will be able to take a leadership role in growing and capturing market share. Let me now update you on our long-acting Factor VIIa-CTP for the treatment of bleeding episodes in hemophilia A or B patients with inhibitors to Factor VIII or Factor IX. We are nearing completion of a Phase 2a dose escalation study of intravenously administered Factor VIIa-CTP to determine safety and explore efficacy endpoints in 24 patients in the United States. A Phase 1 study of subcutaneous administration of this drug healthy volunteer is ongoing. We expect to have the safety information by year-end. Manufacturing scale up to produce efficient drug product for the long-term toxicology and upcoming pivotal efficacy of safety studies are progressing as planned. Let me now turn to OPK88004, a once daily orally administered selective androgen receptor modulator or SARM to treatment with BPH. This compound demonstrated a significant decrease in fat mass and increased muscle mass. And a lowering trend at PSA level in the Phase 2 study in 350 male subjects. We plan to initiate a Phase 2b dose range study in the second half of this year to evaluate effects of OPK88004 to reduce prostate size and provide anabolic therapeutic effects in men with benign prostate hypertrophy or BPH, which is in a large prostate. This is a significant opportunity for us. BPH is common to aged men affection over 50 million men in United States. BPH is one of the 10 most common and costly diseases in men older than 50 years of age in the United States. We are continuing to progress our other late stage pipeline products including OPK88003, a once weekly dual GLP1-Glucagon agonist for which we will undertake a Phase 2b dose escalation study to evaluate weight loss and glucose control. Data from a Phase 2 study of 420 subjects with type 2 diabetes showed OPK88004 with significantly superior weight loss compared with a currently approved extended release exenatide and placebo, and also demonstrated a similar reduction of hemoglobin A1c, a recognized marker of sugar metabolism. During the first quarter, we made progress with our AntagoNAT our anti-Natural Antisense Transcripts and an OPKO platform technology in which single strand oligonucleotide molecules are designed to interfere with regulatory gene expression in order to enhance production of endogenous functional proteins. We recently receive U.S. and EU orphan drug designation for AntagoNAT, OPK88001, the treatment of Dravet Syndrome. The majority of Dravet Syndrome patients are reported to have a mutation of the SCN1A gene which results in a severe intractable form of epilepsy that begins at a young age of three to six months old. We are near to filing an IND for Phase 2 study of this drug in the United States. Turning now to our diagnostic and laboratory business. Bio-Reference Laboratories continues to post steady financial progress with the bulk of revenue coming from traditional reference lab testing along with the growth of our 4Kscore tests. We continue to build the foundation for positive reimbursement at 4Kscore test. And last year the American Medical Association granted a CPT one code for 4Kscore effective as of January 1, 2017. The CMS national approved rate for 2017 for 4Kscore is $602. Novitas has been paying and continues to pay for 4Kscore Medicare claims. In addition 4Kscores included in key prostate cancer guidelines such as the 2016 National Comprehensive Cancer Network U.S. and the 2016 European Association of Urology prostate cancer guidelines. To date, we have a number of positive regional corporate decisions with commercial payers with pricing agreements in place. As we previously reported, Novitas Solutions is the Medicare Administrative Contract, or MAC, that matters to 4Kscore as it is responsible for New Jersey where our Bio-Reference lab facility is located. All 4Kscore blood samples are sent to that facility and all test processing takes place there [indiscernible] resides. Over 8,600 prescribers have ordered the 4Kscore test, and over 18,600 test were performed in the first quarter this year, which represents growth of more than 100% from the first three months of 2016. We have successfully completed a second perspective blinded clinical trial involving veteran’s affairs hospitals across the United States. The 366 patient cohort comprised predominantly of African-Americans. Prostate cancer disproportionately affects African-American men with the highest prostate cancer rate in the world. 4Kscore was shown to accurately identify risk of high-grade prostate cancer disease in this cohort. A podium presentation of the results of this study will be presented at the upcoming annual meeting of the American Urological Association in Boston on Tuesday May 16 at 10 A.M. along with several other podium and poster presentations presented at the meeting involving the 4Kscore. Additionally, investigators involved in the U.S. validation study have submitted a manuscript based on analysis of patients in that study who on biopsy were diagnosed with low grade or Gleason 6 cancer, and went on to have a radical prostatectomy. The analysis demonstrated that the 4Kscore was a significant predictor of cancer upgrades in other words from Gleason 6 to Gleason 7 or higher as confirmed upon radical prostatectomy. Moving out of the Claros 1 point-of-care system, our novel system should provide rapid high performance blood test result at the point of care. Claros 1 can run immunoassay tests in the physician’s office or hospital nurses station using a single drop of blood. Negating the need for a full blood draw sent to a centralized reference laboratory. We expect to report precision data for our first test Claros 1 PSA at the American Association of Clinical Chemistry Meeting in late July or early August. We plan to submit a PMA with the FDA in the second half of the year for our Claros 1 PSA test. We plan to utilize Bio-Reference Labs in marketing, sales, and distribution resources for the launch of the Claros 1 PSA test in the United States. We continue to develop other Claros 1 tests and testosterone is next in line for submission. GeneDx our high-value genetic testing unit has been very active. In March, we had a prominent presence at the American College of Medical Genetics and Genomics Annual Meeting, where we presented a 14 poster and four platform presentations about exome sequencing and other genetic testing in a variety of diseases. To further expand our clinical of genomics programme, whole genome sequencing will be offered to clinicians and research programs. Exome sequencing options will soon be offered to healthy individuals who – because of family history, fertility or pregnancy or more general concerns who would like to have more genetic information about themselves. During the first quarter our GenPath, Women's Health subsidiary introduced ClariTest, a non-invasive prenatal test or NIPT initially to be performed alumina on the verified platform. And IP testing has become a valuable addition for prenatal care. We are pleased to offer the most technically advanced NIPT available on the market. We continue to expand our suite of services at GeneDx, as a leader in innovative genetic testing. As part of its comprehensive test been in growth, GeneDx will be offering pharmacogenetic testing, which examines genetic changes that affect how people process certain prescription medicines. GeneDx’s menu also now includes rapid whole exome sequencing for critically ill patients where results will immediately impact management as well as prenatal whole exome sequencing. So in closing, we are pleased with the progress we’ve made for all business segments these past three months. In particular, our growing revenues are providing increasing cash flow that helps fund our commercial efforts and product development. Our objectives moving forward remain consistent, continue to increase revenue from our diagnostics business, increase contributions from new products, step-up the utilization of the 4Kscore test, expand our GeneDx business, and advance our development programs towards commercialization. Throughout the balance of the year, we expect to achieve a number of important clinical milestones. These include data readout for the sensitivity outlier analysis at a Phase 3 adult hGH-CTP clinical trial and BLA submission. Initiation of the Phase 2 study a reality for the treatment of dialysis patients; submission of a PMA filing for kallikreins-1 PSA point-of-care test, and a 510-K filing for Claros 1 point-of-care testosterone test. Initiation of Phase 2b study of our OPK88004, a once daily oral selective androgen receptor modulator or SARM in patients with BPH enlarged prostate. Initiation of a Phase 2b study of our OPK88003, are once weekly dual GLP1-Glucagon agonist to evaluate weight loss and glucose control. Obtain data from the Phase 2a study of Factor VIIa-CTP IV formulation and from the Phase 1 study of Factor VIIa subcutaneous formulation. Initiation of Phase 2a clinical study of our NK-1 inhibitor for itching in dialysis patients, and initiation of a Phase 2a study of OPK88001 for the treatment of Dravet Syndrome. We look forward to keeping you apprised of our progress about all these programs. Let me turn the call over to Adam for a discussion of our first quarter 2017 financial performance. Adam?
