Thanks Steve. The R&D organization closed 2015 with a number of achievements that helped further lay the groundwork for very important year ahead. And we anticipate in 2016 the pipeline will continue to come into focus with the potential successful achievement of several important milestones. Specifically related to sparsentan, which is our lead development program, the clinical team made a big push in the fourth quarter of 2015 and was able to make up for some of the weakness we saw in enrollment due to the seasonality in the summer months of 2015. I’m happy to report that we’re on-track to have the 100-subject randomized in the DUET study by the end of the first quarter. And this would put us on track for a, top-line readout in the third quarter of 2016. The DUET trial was designed to detect the clinically meaningful reduction in proteinuria after eight weeks of treatment compared to an active control. Based on the fact that angiotensin blockade is commonly used as a backbone of therapy in FSGS. We chose to use irbesartan as the active controlling DUET. And we believe this reflects the real-life therapeutic decision-making the patients and doctors will be faced with. What gives us confidence in sparsentan is the emerging body of mechanistic evidence supported by clinical data and other chronic kidney diseases that show endothelin antagonists have an additive effect on proteinuria over and above that [indiscernible]. In multiple studies using several agents, it’s clear that the proteinuria reducing effect of endothelin receptor antagonists quite significantly. From a safety perspective, the limitation of endothelin receptor antagonist use in chronic kidney diseases has traditionally been fluid retention which can lead to significant complications for this patient population. We hypothesize that the relative selectivity of sparsentan for endothelin Type A receptors over Type B receptors as well as the fact that sparsentan has a built-in angiotensin blockade which has a diuretic fluid losing effect should help mitigate the potential for fluid retention. The fact that we’ve now gone through four data monitoring committee meetings, the last of which was just a week ago, gives us some comfort that the safety profile with sparsentan is generally in-line with clinicians’ expectations. In terms of our regulatory strategy, we made progress in the fourth quarter of 2015 with the official granting of sparsentan’s orphan drug designation in the European Union for the treatment of FSGS. This designation provides good validation of our efforts and ultimately aide our discussions with regulators. We also continued to push forward in our belief that proteinuria is an acceptable surrogate end-point that’s appropriate for Subpart H for accelerated approval. We’ve seen a lot of momentum both from the academic community as well as the agency itself to identify and validate a surrogate end-point in renal disease that can be used in trials to assess the ability of therapeutics to prevent progression to ESRD. Notable efforts in disease areas such as Idiopathic Membranous Nephropathy, which resulted in an excellent publication last year in the Journal of the American Society of Nephrology, supports the fact that proteinuria is coming into focus as a potential Subpart H end-point. Our own discussions with the agency have solidified our belief that proteinuria will be considered for Subpart H approval if the data are robust and supportive. We continue our efforts with key opinion leaders and patient advocacy groups to build a dataset that will help us in our discussions with the agency at the appropriate time. We’ll continue to provide further updates as we near the end of the enrollment period for DUET. Moving to RE-024, which is our novel phosphopantothenate replacement therapy for the treatment of pantothenate kinase-associated neurodegeneration or PKAN. We continued to reach key milestones for the program’s development during the fourth quarter. Most notably, we had an end of Phase 1 meeting with the FDA in December to discuss the next steps for an efficacy trial for RE-024 in PKAN patients. The agency’s feedback was very clear and constructive and we planned to incorporate their guidance and move towards initiating an efficacy trial in PKAN patients later this year. Perhaps equally as important, we submitted and gained acceptance for the presentation of the package of both pre-clinical and clinical data at the ACMG Meeting in March. We’re excited as this is some of the first comprehensive data we’ll be able to get into the public domain. And it’s very supportive of the program’s development thus far. The presentations coming up in a few weeks will cover first: the results of our Phase 1 healthy volunteer study of RE-024 showing the single oral doses ranging from 75 mg up to 1,800 mg for safe and more tolerated. Secondly: a case report of one ex-U.S. PKAN patient receiving RE-024 therapy who, has been monitored for a 12-month period and has demonstrated the therapy is well tolerated. The patient also showed improvement in multiple outcome measures including motor symptoms as measured by the Unified Parkinson’s Disease Rating Scale. Third: development of the first human cellular model in which the silencing of PanK2 by shRNA leads to decreased coenzyme A levels, as well as decreased tubulin and histone acetylation, which are restored following treatment with RE-024. And fourth: mechanism of action studies using isotopically labeled RE-024, demonstrating incorporation of phosphopantothenic acid derived from RE-024 into Coenzyme A in mice. Microdialysis studies in primates also demonstrate RE-024’s ability to distribute to the brain. The four patients receiving RE-024 treatment through physician-initiated studies outside the United States continue on therapy and have now been receiving treatment with 024 for 19 to 25 months altogether. We look forward to the one patient case report that will be presented at ACMG which will provide data on that very first patient to initiate RE-024 treatment. We also continue to encourage the further dissemination of case reports for the remaining patients who are being treated under physician initiated studies in order to contribute to the body of knowledge surrounding RE-024 and PKAN. Last but not least in the pipeline is RE-034, which continued to move ahead of the fourth quarter with manufacturing and scale-up activities which will enable further development. These efforts are ongoing and will enable us to reach a decision on the initiation of IND enabling studies in the late spring or early summer. Now, shifting the focus to our support of the marketed portfolio, our R&D team continues to work very closely with the commercial organization to ensure we’re combining our efforts to optimize the effectiveness and reach of our products. Regarding Thiola, this means we continue our efforts to produce a novel, more patient friendly formulation in conjunction with our partners’ admission [indiscernible]. For Chenodal, our team’s focus has been on two distinct goals. The first is broadening our education in the disease awareness efforts through the CTX prevalence study they kicked off last year. And the second is the discussion with the agency to include CTX on the Chenodal label. So, first, with regards to the prevalence study, we’ve continued to enroll and activate research sites in that study with a goal of having subjects screen as soon as possible. As Steve mentioned, this long-term study will have the dual purposes of establishing the prevalence of CTX in this enriched population as well as keeping CTX top of mind within the physician space that could be the first to pick-up bilateral cataract which is one of the early signs of CTX. Our efforts at getting the Chenodal label adjusted to include CTX are impressing. We continue in dialogue with the agency and hope to align on an acceptable pathway in the first half of this year. Our belief is that a label that reflects the true nature of usage of Chenodal is in the best interest of the patient community. And we continue to enjoy the full support of the patient advocacy groups that are in this space. On Cholbam, our team has been focusing on fulfilling our post marketing commitments which include the development of a disease registry as well as a development of a quantitative diagnostic tool to measure urinary bile acids. Both efforts are proceeding according to plan and we anticipate we’ll be able to meet the FDA obligations on schedule. In terms of earlier stage discovery work, our team announced in November the initiation of the research collaboration with the Grace Wilsey Foundation as well as the University of Notre Dame, to do early stage discovery work towards the therapeutics for NGLY1 deficiency. This collaboration is very exciting and focuses on a novel target for the disease. If we’re successful in target validation and asset development, these efforts may lay the groundwork for the development of the novel small-molecule therapy for this disease. This model is collaboration between industry, academia and patient advocacy is beginning to become widespread in the rare disease community. And we look forward to working with our collaborators to move the field forward. Further updates will be forthcoming as we make progress. And with that, I’ll turn it over to Laura to walk through the financials.
