Thanks, Steve. I’m happy to report that we made great progress in the second quarter, both on the development pipeline as well as on our portfolio of marketed products. In terms of our development efforts, our top priority remains enrolling patients into the DUET trial for Sparsentan. Sparsentan is our dual endothelin receptor antagonist plus angiotensin receptor blocker that’s in development for the treatment of focal segmental glomerular sclerosis or FSGS. As you might recall, our targeted step full enrollment of 100 FSGS patients by the end of 2015 and we remain on tract to accomplish that. Our clinical operations group is working closely with the main advocacy group in FSGS, NephCure, as well as the Neptune Consortium of Academic Centers to make sure as many patients and physicians as possible, know about the DUET trial and have the opportunity to participate. Approximately 40 sites are active across the U.S and Europe. Our team is focused on executing the DUET trial and enabling a robust data readout as soon as possible. Next in the pipeline is RE-024 which is our novel phosphopantothenate replacement therapy for the treatment of pantothenate kinase-associated neurodegeneration or PKAN. We have very active second quarter in which RE-024 was granted both orphan drug status and fast track designation by the FDA. Also, our investigational new drug application or IND was cleared by the FDA, allowing us to initiate a Phase 1 study to assess safety and tolerability of RE-024 in healthy adult volunteers. We remain on track to have data enhanced by the end of the year. Our plan is to engage in discussion with the FDA, once we have the Phase 1 data available, and we will agree to the next phase of clinical development which will involve treating PKAN patients. We looking forward to engaging with the agency and working together to ensure PKAN patients have access to RE-024 as soon as possible in the context of a controlled clinical trial. Meanwhile, all four ex-U.S patients who have been on RE-024 through physician initiated studies remain on therapy. Further data on these patients maybe submitted for publication at the discretion of the treating physicians. In the early stage portfolio of the settlement of the Questcor litigation gives us added flexibility in determining the next steps in the RE-034 program. RE-034 is our novel formulation of the first 24 amino acids of ACTH. The program remains an early preclinical stage and may move to IND enabling studies within the next 12 months. Our team continues to evaluate clinical development options that would unlock value for the program either in our own hands or potential in partnership with an external collaborator. Moving to our portfolio of marketed products, the R&D team is constantly looking to further develop our commercial products and ensure that they’re delivering optimal value for patients. First, with regard to Chenodal, we continue to work with the FDA to request that the label be changed to reflect the true nature of Chenodal’s current use, which is the treatment of patients with cerebrotendinous xanthomatosis or CTX. Our medical team is working with treating physicians to gather data and enable a submission to the agency to support this label change. The team is also preparing to launch the CTX prevalent study in approximately 50 sites, pending IRB approvals. We are enlisting investigators to identify patients with the history of juvenile bilateral cataracts to be reviewed in screen for CTX. Bilateral cataracts were often the first discernible manifestation of CTX. And we think that this study will lend inside into the true prevalence of CTX as well as be an important step in changing the way physicians think about diagnosing CTX. We expect the first subject in this screening study will be enrolled later this year. We hope that our efforts will lead to earlier diagnosis in treatment of CTX patients and prevent the progression of the irreparable cognitive decline. Regarding Cholbam, the medical team has been very active in supporting the launch of the product, which as Steve mentioned is being going according to plan. We continue to work with the leading specialist in the field to develop next generation diagnostics, which will improve the efficiency with which bile acid synthesis disorder patients are identified. We believe these efforts will ultimately lead to a better diagnostic paradigm for these patients. For Thiola, our medical education initiatives continue in an effort to raise awareness of cystinuria and the role of Thiola in preventing cystine kidney stones. We’ve undertaken outreach to nearly all key opinion leaders in the United States. Publications and K-series are also in progress that will augment the medical literature supporting the use of Thiola in cystinuria. Lastly, I wanted to share that we’ve convened a Scientific Advisory Board to provide valuable guidance and direction for the R&D team. This group consists of five outstanding and experienced individuals, Dr. Alan Beggs, Dr. Randall Carpenter, Dr. Tim Cote, Dr. Brendan Lee and Dr. Stuart Swiedler. Together they bring significant scientific clinical and regulatory expertise to bear on the entire Retrophin portfolio. We are privileged to have these distinguished members of the rare disease community to serve on our Scientific Advisory Board on an ongoing basis. With that, I’ll turn it over to Laura, to walk through the financials.
