“I am pleased with the continued advancement of our first-in-class fosmetpantotenate and sparsentan programs and look forward to generating our first pivotal top-line data readout from the FORT Study next year. Additionally, the Phase 2 proof-of-concept study of CNSA-001 in PKU is underway and we are looking forward to seeing the results from that study in the first half of 2019,” said Stephen Aselage, chief executive officer of Retrophin. “The third quarter also continued our four-year history of delivering period over period revenue growth; while revenue came in below our internal expectations for the quarter, we expect to continue the period over period revenue growth trend in the fourth quarter. Overall, the progress made in the third quarter sets us up to meet additional strategic milestones and end 2018 well-positioned for the coming year.”

Quarter Ended September 30, 2018

Net product sales for the third quarter of 2018 were $40.7 million, compared to $40.3 million for the same period in 2017. For the nine months ended September 30, 2018, net product sales were $120.5 million, compared to $112.8 million for the same period in 2017.

Research and development (R&D) expenses for the third quarter of 2018 were $32.4 million, compared to $19.6 million for the same period in 2017. For the nine months ended September 30, 2018, R&D expenses were $91.8 million, compared to $58.6 million for the same period in 2017. The difference is largely attributable to support of non-clinical and clinical efforts related to fosmetpantotenate and sparsentan, as well as development funding to support the advancement of CNSA-001. On a non-GAAP adjusted basis, R&D expenses were $30.6 million for the third quarter of 2018, compared to $17.5 million for the same period in 2017.

Selling, general and administrative (SG&A) expenses for the third quarter of 2018 were $26.1 million, compared to $24.9 million for the same period in 2017. For the nine months ended September 30, 2018, SG&A expenses were $77.7 million, compared to $74.7 million for the same period in 2017. The difference is largely attributable to an increase in commercial expenses. On a non-GAAP adjusted basis, SG&A expenses were $18.3 million for the third quarter of 2018, compared to $15.4 million for the same period in 2017.

Total other expense for the third quarter of 2018 was $18.5 million, compared to $8.4 million for the same period in 2017. The difference is largely attributable to higher interest expense and a loss on early extinguishment of debt related to the repurchase of approximately half of the Company’s outstanding convertible notes due 2019 effected in September 2018.

Net loss for the third quarter of 2018 was $54.5 million, or $1.34 per basic share, compared to $17.8 million, or $0.46 per basic share for the same period in 2017. For the nine months ended September 30, 2018, net loss was $95.2 million, compared to $42.1 million for the same period in 2017. On a non-GAAP adjusted basis, net loss for the third quarter of 2018 was $27.8 million, or $0.68 per basic share, compared to net income of $5.9 million, or $0.15 per basic share for the same period in 2017.

As of September 30, 2018, the Company had cash, cash equivalents and marketable securities of $478.8 million. This includes approximately $227 million raised in September 2018, net of expenses and repurchase of approximately half of the Company’s outstanding convertible notes due 2019.

Program Updates

Fosmetpantotenate

• The Company continues to enroll patients in the Phase 3 FORT Study, an international, pivotal clinical trial assessing the safety and efficacy of fosmetpantotenate in approximately 82 patients with PKAN aged 6 to 65 years. The primary endpoint in the study is the change from baseline in the Pantothenate Kinase-Associated Neurodegeneration Activities of Daily Living (PKAN-ADL) scale through 24 weeks of treatment. After completing the 24-week treatment period, all patients will be eligible to receive fosmetpantotenate as part of an open-label extension. The FORT Study is expected to be registration-enabling in the U.S. and Europe and is being conducted under a Special Protocol Assessment (SPA) agreement, which indicates concurrence by the FDA that the design of the trial can adequately support the filing of an NDA. Top-line data are expected in the second half of 2019.
  
• Four PKAN patients receiving fosmetpantotenate for more than four years under physician-initiated treatment outside of the U.S. continue to receive therapy and remain stable.

Sparsentan

• The Company continues to enroll patients in the pivotal Phase 3 DUPLEX Study, a global, randomized, multicenter, double-blind, parallel-arm, active-controlled Phase 3 clinical trial evaluating the safety and efficacy of sparsentan in approximately 300 patients with FSGS aged 8 to 75 years. The DUPLEX Study protocol provides for an unblinded analysis of at least 190 patients to be performed after 36 weeks of treatment to evaluate the interim efficacy endpoint – the proportion of patients achieving a FSGS partial remission of proteinuria endpoint (FPRE), which is defined as urine protein-to-creatinine ratio (Up/C) ≤1.5 g/g and a >40 percent reduction in Up/C from baseline, at Week 36. While the confirmatory endpoint of the study is the change in slope of estimated glomerular filtration rate (eGFR) after 108 weeks of treatment, successful achievement of the 36-week interim efficacy endpoint is expected to serve as the basis for Subpart H accelerated approval in the U.S. and Conditional Marketing Authorization (CMA) consideration in Europe. Top-line data from the 36-week interim endpoint efficacy analysis are expected in the second half of 2020.
  
• In October 2018, the Company presented new positive data from the ongoing open-label extension of the Phase 2 DUET study of sparsentan in FSGS at the American Society of Nephrology (ASN) Kidney Week 2018. Key findings from the 84-week analysis suggested patients with FSGS who remained on sparsentan during the open-label period achieved additional progressive reduction of proteinuria, and an increasing proportion of patients achieved FPRE. In addition, treatment with sparsentan in the open-label extension was associated with a stabilization of eGFR out to week 84. Sixty-two patients continue to receive treatment with sparsentan in the ongoing open-label extension of DUET.
  
• In September 2018, the Company presented the design of its upcoming pivotal Phase 3 PROTECT Study of sparsentan in IgAN at the 15th International Symposium on IgA Nephropathy. The PROTECT Study is a global, randomized, multicenter, double-blind, parallel-arm, active-controlled Phase 3 clinical trial evaluating the safety and efficacy of sparsentan in approximately 280 patients with IgAN aged 18 years or older. The primary efficacy endpoint in the PROTECT Study is the change in proteinuria (urine protein-to-creatinine ratio) from baseline after 36 weeks of treatment. Retrophin expects that successful achievement of this endpoint will serve as the basis for Subpart H accelerated approval of sparsentan in the U.S. and CMA consideration in Europe. Secondary efficacy endpoints include change in eGFR from baseline to four weeks post-cessation of randomized treatment, as well as the rate of change in eGFR over 52-week and 104-week periods following the first six weeks of randomized treatment. Retrophin expects to initiate the PROTECT Study during the fourth quarter of 2018.

CNSA-001

• Patient dosing has commenced in the Phase 2 proof-of-concept study evaluating CNSA-001 in patients with PKU. CNSA-001 is advancing under a joint development and option agreement with Censa Pharmaceuticals. The Phase 2 study is a randomized, double crossover, open-label, active-controlled study of multiple doses of CNSA-001 compared to the maximum recommended dose of the current standard of care. Top-line data are expected to be available in the first half of 2019.

Thiola

• In the third quarter of 2018, an NDA was submitted to the FDA for approval of the new formulation of Thiola for the treatment of cystinuria. Pending acceptance of the submission and subsequent approval, the Company expects to begin marketing the new formulation in 2019.

Use of Non-GAAP Financial Measures

To supplement Retrophin’s financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses certain non-GAAP adjusted financial measures in this press release and the accompanying tables. The Company believes that these non-GAAP financial measures are helpful in understanding its past financial performance and potential future results. They are not meant to be considered in isolation or as a substitute for comparable GAAP measures, and should be read in conjunction with the consolidated financial statements prepared in accordance with GAAP. Retrophin’s management regularly uses these supplemental non-GAAP financial measures internally to understand, manage and evaluate its business and make operating decisions. In addition, Retrophin believes that the use of these non-GAAP measures enhances the ability of investors to compare its results from period to period and allows for greater transparency with respect to key financial metrics the Company uses in making operating decisions.

Investors should note that these non-GAAP financial measures are not prepared under any comprehensive set of accounting rules or principles and do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. Investors should also note that these non-GAAP financial measures have no standardized meaning prescribed by GAAP and, therefore, have limits in their usefulness to investors. In addition, from time to time in the future the Company may exclude other items, or cease to exclude items that it has historically excluded, for purposes of its non-GAAP financial measures; because of the non-standardized definitions, the non-GAAP financial measures as used by the Company in this press release and the accompanying tables may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by the Company’s competitors and other companies.

As used in this press release, (i) the historical non-GAAP net income (loss) measures exclude from GAAP net income (loss), as applicable, stock-based compensation expense, amortization and depreciation expense, revaluation of acquisition related contingent consideration, change in fair value of derivative instruments and income tax; (ii) the historical non-GAAP SG&A expense measures exclude from GAAP SG&A expenses, as applicable, stock-based compensation expense, and amortization and depreciation expense; (iii) the historical non-GAAP R&D expense measures exclude from GAAP R&D expenses, as applicable, stock-based compensation expense, and depreciation and amortization expense.
