Steve?.

Thanks you, Chris. Good afternoon, everyone and thank you for joining us to talk about the progress we made in 2015 and our outlook for 2016. We closed ‘15 with fourth quarter performance that continued the momentum we built earlier in the year and leaves us well-positioned for to be a transformational 2016 for Retrophin.

From an operating perspective, we grew top-line revenues for the seventh consecutive quarter and leveraged our cost controls to remain disciplined in our deployment of capital, which resulted in another quarter of positive operating cash flow generation.

The growth in total net product sales to $30.4 million for the quarter was driven by new patient admissions to all three products. Thiola was the largest contributor to this growth in the fourth quarter and continues to add patients on a weekly basis.

2015 was about expanding our knowledge of the cystinuria marketplace and understanding the true potential for the product. Specifically we were focused on reaching the remaining portion of cystinuria patients. We’ve been treated with Thiola prior to the supply disruption in 2014 and those who were aware of the therapy but had not yet received it.

2016 will be about applying this knowledge to ensure we reach the maximum number of patients possible within what we believe is a population of 4,000 to 5,000 cystine stone forming patients, who could benefit from Thiola.

We’ll do that, we’re primarily targeting diagnosed patients who maybe on earlier lines of treatment or even other therapies, specifically we have already initiated several programs to improve our commercial efficiency and gain greater traction in the field. One way we hope to spur further growth is through a new program we launched in late January.

This effort gives us access to laboratory data which will direct us more quickly to physicians with diagnosed patients under their care. We anticipate this may uncover nephrologists or urologists that our sales force had not previously engaged. And I’m encouraged by some returns that we have already seen from the program.

It’s too early to determine the sustainable impact but we should have a good handle on the value of this new program by mid-year. We will also be spending more time connecting with patients to gain an even better understanding of their treatment expectations and educate them on the importance of keeping cystine levels below the limit of solubility.

We believe the patients should have higher expectations when it comes to therapeutic outcomes, for some that will be as simple as optimizing their dosing regimen and with others it may be considering Thiola earlier in the treatment paradigm.

In the field, our sales force and medical affairs teams will be educating physicians and thought leaders to build a better understanding of the utility of the 24-hour urine test and the importance of seeking optimal treatment regiments. All in an effort to our patients get closer to a state of complete stone remission.

Compliance rates for Thiola patients continue to improve and are now covering around 85%.

This is a gratifying result of the significant investments we continue to make in the many services we provide to support patients, we as the Thiola Total Care Hub, most importantly it means people are generally seeing greater benefit than they were before we started distributing Thiola as historical rates were closer to 50%.

Last quarter we announced that we committed efforts toward a new more patient-friendly formulation of Thiola and we’re working closely with our manufacturing partners to begin development work on that formulation.

Switching to Cholbam, our treatment for bile acid synthesis and Zellweger spectrum disorders, in the fourth quarter we saw some new patients initiate therapy. The uptake thus far has been a bit slower than initially expected. But that is not uncommon when launching new treatments targeting rare diseases.

We continue to believe that there are roughly 200 to 300 patients that would benefit from Cholbam therapy. And we are adjusting our strategy to accelerate our pace and start reaching those patients more quickly.

Specifically, in order to fully capture the opportunity with Zellweger spectrum disorder patients, we’ve expanded our target audience to include clinical geneticists. We are focusing on about 70 centers of excellence as these appear to be where the specialist closest to diagnosis for many of these patients, reside.

We’ve also identified a way to simplify and accelerate the diagnostic pathways for specialists encountering cholestasis which is usually a presenting symptom of bile acid synthesis and Zellweger spectrum disorders.

We’re partnering with the leading academic genetics laboratories to enable free access to a comprehensive genetic panel for any patient with cholestasis and other symptoms that could point to the possibility of these disorders.

We believe access to this test will enable higher diagnosis rates of the disorders where Cholbam can help and most importantly allow for earlier intervention which is critical to better outcomes for these vulnerable patients.

If left untreated, many of these patients may develop life-threatening liver injury, which can lead to transplant or even death. So we will continue to expand our efforts in trying to reach as many of these patients as possible. Turning to ex-U.S. efforts where the landscape is evolving and we continue to assess the overall potential of Cholbam.

We’re encouraged by the EMEA’s decision to reauthorize the marketing rights in November, as that decision allows us to take further steps toward launching in several countries in 2016. We still have ways to go and at this point we do not expect a significant top-line revenue contribution from ex-U.S. to be realized in 2016.

But we do anticipate being able to get more clarity on the overall opportunity later this year. Wrapping up the commercial portfolio discussion with Chenodal where the patient base group been in the fourth quarter. Efforts continued towards our goal of increasing awareness and enabling earlier diagnosis of CTX.

With the severely degenerative condition at a medium diagnosis age in the mid-30s, we know we can make a difference in patients’ lives if we can get more physicians thinking about CTX earlier. To that end, I’m happy with the progress we’ve been able to make with our prevalence study which began enrolling patients in the fourth quarter.

We expect that momentum to continue through 2016. And hope that will provide meaningful insights into the diagnostic patterns of the population while also gaining a better sense of the true prevalence of CTX.

With regards to altering the label, preparations continue for engaging the FDA further this year in the hopes of finding a mutual agreeable pathway for inclusion of CTX to the label. From a business development standpoint, our focus has not shifted. We continue to be engaged on many opportunities.

We’re primarily focused on rare disease assets that fall in one of two buckets, commercial assets that have some IP or exclusivity that we can bring in and execute without a significant build-out of our infrastructure and later stage development assets that are either overlooked or not as broadly understood.

We are not planning on bringing in development stage assets that carry significant risk or have an unclear path toward near-term value creation. The environment is certainly shifting and we’re seeing some more willingness to engage on some assets that we work than we were last year.

So, we’re hopeful to have additional opportunities to look at as we move through the year. Touching on R&D before I hand it out to Alvin to walk you through these updates, 2016 is a very important year for the pipeline. And I continue to be hopeful about our chances for success for sparsentan and RE-024.

We’re getting closer to enrolling our last patient in the DUET trial and look forward to hopefully confirming what we believe will be a robust reduction in proteinuria when we see the top-line readout later this year. In a few weeks, we’ll get to showcase the RE-024 program with data at the American College of Medical Genetics.

Alvin and his team have done an exceptional job in getting a package of data accepted for presentation that will provide clarity into the potential of RE-024 as a viable treatment for people suffering from PKAN. The other key milestone will be the initiation of the next trial of RE-024 which will be evaluating efficacy in the PKAN patient population.

So, with that I will now turn the call over to Alvin to give you a more in-depth update.

Alvin?.

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..

Thank you, Alvin. Net product sales from our commercial portfolio consisting of, Thiola, Cholbam, and Chenodal were $30.4 million in the fourth quarter and $99.9 million for the full year 2015.

The increase for the fourth quarter over the same period in 2014 is due to growth in the number of patients receiving Thiola and Chenodal treatments and the addition of Cholbam to the commercial portfolio. We reported a GAAP net loss of $2.5 million for the fourth quarter and a net income of $117.2 million for the full year 2015.

Adjusting for extraordinary and one-time expenses, net income was $2.6 million for the quarter and $11.8 million for the full-year 2015.

Significant adjustments for the quarter included $18.5 million of non-GAAP operating loss adjustments offset by a $10.5 million income tax benefit and a net benefit of $2.9 million related to the company’s derivative instruments.

Research and development expenses on a GAAP basis were $15.5 million for the fourth quarter and $50.4 million for the full-year 2015.

The increase in the fourth quarter is a result of increased compensation and clinical trial expense related to the advancement of our lead development candidate sparsentan, as it nears completion of enrollment of the DUET study. On an adjusted basis, R&D expense for the fourth quarter was $12.6 million and $40.3 million for the full-year 2015.

Relevant non-cash expenses for the fourth quarter included $2.8 million of stock-based compensation and amortization. Selling, general and administrative expenses were $22.7 million on a GAAP basis in the fourth quarter and $79.5 million for the full-year 2015.

The increase in the fourth quarter is largely due to increased compensation and amortization related to the expansion of commercial effort and the addition of Cholbam to the commercial portfolio. On an adjusted basis, SG&A expense for the fourth quarter was $13.8 million and $46 million for the full-year 2015.

Significant one-time and non-cash adjustments for the quarter consisted of $8.5 million related to stock compensation and depreciation and amortization. A quick note on taxes, we ended the year with an $11.8 million benefit.

This benefit was a result of truing up the release of evaluation allowance and the utilization of net operating loss carry-forwards related to the sale of the PRV.

At year end, the company also reported a corresponding deferred tax liability of $24.3 million on the balance sheet primarily related to future taxes payable on the remaining two payments that we will receive as a result of the PRV sale. Prepaid taxes of $8.1 million will be applied against this deferred tax liability when it becomes due.

As of December 31, 2015, we had approximately $322 million in cash and cash equivalents, marketable securities and notes receivable from the sale of our PRV.

The market increase over the cash balance of $27.8 million on December 31, 2014 can be largely attributed to the company’s follow-on equity offering in March and the initial payment and remaining notes receivable from the sale of the PRV.

Briefly looking ahead, as mentioned earlier, in 2016, our emphasis will be on our development program and as such we expect to allocate further investments in our lead pipeline assets sparsentan and RE-024 to give them the best chance of reaching patients as quickly as possible.

As a result, we expect operating expenses and cash flow from operations to vary throughout 2016. I’m proud of our progress in 2015.

We significantly strengthened the balance sheet, implemented new cost control measures and focused our spend in the areas that offer the greatest future returns and these achievements have put us in a position of financial strength heading into the new year. I’ll now turn the call back over to Steve for his closing remarks..

Thanks Laura. I do want to take a step back and recognize the progress that was made in 2015 as a result of our employees’ dedication and hard-work while executing on the strategic plans.

There were many significant achievements in the year including but not limited to, top-line growth each quarter with broad expansion of access for patients through all of our commercial products, numerous regulatory milestones that will ensure additional value for our pipeline assets including infant drug and fast-track designations, the acquisition and approval of Cholbam and the subsequent PRV sale and the ramping up of enrollment in the DUET trial for sparsentan and RE-024 moving into the clinic in the U.S and completing its Phase 1 trial in healthy volunteers.

From a financial perspective, we entered 2015 with a $56 million top-line run rate and operating expenses we’re only just started to benefit from the controls put in place at the end of 2014. Our balance sheet was limited to only $28 million in ash alongside expensive restrictive debt and convertible notes.

We now move into 2016 with top-line growth expected to reach $130 million to $140 million and our fortified balance sheet consisting of more than $320 million in cash receivables with no restricted debt. This progress enables us to set our sights higher.

We plan to leverage our advancements from last year to move through 2016 with a focus of moving our pipeline forward and continuing commercial execution so that we can showcase the true value potential of the company for our shareholders. I will now turn the call back over to Chris to open up the lines for questions.

Chris?.

Thanks Steve.

Lauren, can we open up the line for questions please?.

Yes, sir. [Operator Instructions]. Our first question comes from Joseph Schwartz from Leerink Partners. Your line is open..

Hi everyone Mrs. Brad in for Joe. Thanks for taking my question. I’m curious Thiola, how much revenue growth do you feel is less then specifically what are the drivers in this direction you specifically mentioned the patient-friendly formulation and development.

I’m curious to hear any more thoughts or color around that and timing for that? And then conversely, how much of the barrier to growth if at all if the action announcement improvements earlier this month? Thank you..

Sure, we see, thanks. We see significant upside with Thiola really through all of this year and into 2017, we feel like we’ve got a good start. We’ve seen good growth but this is a product that takes time, takes education.

And one of the things that I mentioned during the script was, there are, we feel patients in many centers scattered around the country. We just haven’t been able to find yet.

We feel that use of this laboratory data is going to allow us to direct our sales force really to become much more efficient, much more effective in finding those patients and getting those patients on to therapy. So, significant upside to continue, we’re going to grow that product for the foreseeable future.

Now with regards to the second part of your question related to the compounding pharmacy we don’t see any impact at all on our current or future business. It’s a formulation that we don’t think makes sense, we don’t think it should come to market.

It’s a product that if it comes out as described would be considered a new drug, not just a compounded version of Thiola. And you can’t launch the new drug in the United States without FDA approval. So, we’re not losing any sleep about that one..

Okay, great. Thanks for the color.

And on the patient-friendly formulation that was mentioned, when can we expect more details around what that would look like and when that could be launching?.

Yes, I don’t anticipate of really providing any details on that until we get pretty close to being able to roll it out for utilization. And that would be probably 2017 some time. And as we get closer we’ll give you a little tighter timeline. But we’re still early on with that.

And the only thing I’d be willing to say certainly right now is we won’t get it out in ‘16, it will be at least ‘17 before it comes out..

Okay, great. Thanks for the answers. Appreciate it..

Sure..

[Operator Instructions]. And I’m showing no questions at this time..

Great. Thank you, Lauren. With that we’ll wrap up the call. And we look forward to hearing or giving you all our progress next quarter. Thank you for joining..

Ladies and gentlemen, thank you for your participation in today’s conference. This concludes the program. You may all disconnect. Everyone have a great day..
