• Cash, cash equivalents and marketable securities, as of June 30, 2019, totaled $425.9 million

“We are looking forward to the upcoming data read-out from our Phase 3 FORT Study this quarter, which if successful would support NDA and MAA submissions to potentially make fosmetpantotenate the first approved treatment for PKAN,” said Eric Dube, Ph.D., chief executive officer of Retrophin. “Beyond fosmetpantotenate, our teams remain focused on execution and the goal of delivering new treatment options through the continued advancement of our two pivotal studies evaluating sparsentan for FSGS and IgA nephropathy, and the recent approval and launch of THIOLA EC for the treatment of cystinuria.”

Quarter Ended June 30, 2019

Net product sales for the second quarter of 2019 were $44.7 million, compared to $41.3 million for the same period in 2018. For the six months ended June 30, 2019, net product sales were $84.3 million, compared to $79.8 million for the same period in 2018. The increase in net product sales is attributable to growth across the Company’s commercial products. Growth of the Company’s net product sales for the full year 2019 is expected to be in line with the growth rate seen for the full year 2018.

Research and development (R&D) expenses for the second quarter of 2019 were $37.9 million, compared to $34.5 million for the same period in 2018. For the six months ended June 30, 2019, R&D expenses were $71.4 million, compared to $59.1 million for the same period in 2018. The difference is largely attributable to support of clinical and product development efforts related to fosmetpantotenate and sparsentan. On a non-GAAP adjusted basis, R&D expenses were $35.8 million for the second quarter of 2019, compared to $32.6 million for the same period in 2018.

Selling, general and administrative (SG&A) expenses for the second quarter of 2019 were $39.0 million, compared to $25.1 million for the same period in 2018. For the six months ended June 30, 2019, SG&A expenses were $71.6 million, compared to $51.6 million for the same period in 2018. The difference is largely attributable to increased headcount as a result of the Company’s operational growth, and professional fees. On a non-GAAP adjusted basis, SG&A expenses were $30.4 million for the second quarter of 2019, compared to $16.9 million for the same period in 2018.

Total other expense for the second quarter of 2019 was $2.1 million, compared to $0.6 million for the same period in 2018. The difference is largely attributable to higher interest expense related to the Company’s 2025 convertible notes issued in September 2018.

Net loss for the second quarter of 2019 was $38.7 million, or $0.92 per basic share, compared to $22.3 million, or $0.56 per basic share for the same period in 2018. For the six months ended June 30, 2019, net loss was $79.7 million, compared to $40.7 million for the same period in 2018. On a non-GAAP adjusted basis, net loss for the second quarter of 2019 was $24.5 million, or $0.58 per basic share, compared to a net loss of $9.9 million, or $0.25 per basic share for the same period in 2018.

As of June 30, 2019, the Company had cash, cash equivalents and marketable securities of $425.9 million.

Program Updates

Fosmetpantotenate

• Top-line data from the pivotal Phase 3 FORT Study are expected in the third quarter of 2019. The FORT Study is an international, pivotal clinical trial assessing the safety and efficacy of fosmetpantotenate in patients with PKAN. 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 are 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, if the data are positive, the design of the trial can adequately support the filing of an NDA.

Sparsentan

• The Company continues to enroll patients with FSGS in the pivotal Phase 3 DUPLEX Study, a global, randomized, multicenter, double-blind, parallel-arm, active-controlled clinical trial evaluating the safety and efficacy of sparsentan in approximately 300 patients. 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 interim 36-week proteinuria endpoint is expected to serve as the basis for submission of an NDA under the Subpart H accelerated approval pathway in the U.S. and Conditional Marketing Authorization (CMA) consideration in Europe. Top-line efficacy data from the 36-week proteinuria endpoint analysis are expected in the first half of 2021.
   
• The PROTECT Study, a global, randomized, multicenter, double-blind, parallel-arm, active-controlled pivotal Phase 3 clinical trial evaluating the safety and efficacy of sparsentan in approximately 280 patients with IgAN, continues to enroll. 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. Successful achievement of this endpoint is expected to support submission of an NDA under the Subpart H accelerated approval pathway in the U.S., as well as an application for 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. Top-line efficacy data from the 36-week proteinuria endpoint analysis are expected in the first half of 2022.

CNSA-001

• Following a strategic review of the CNSA-001 program in patients with phenylketonuria (PKU), the Company made the decision to decline to exercise its option to acquire Censa Pharmaceuticals and accordingly discontinue its joint development program for CNSA-001.

Alagille Syndrome CRADA

• In the second quarter of 2019, the Company entered into a three-way Cooperative Research and Development Agreement (CRADA) with the National Institutes of Health's National Center for Advancing Translational Sciences (NCATS) and patient advocacy foundation Alagille Syndrome Alliance to collaborate on research efforts aimed at the identification and development of potential therapeutics for Alagille syndrome. This CRADA broadens Retrophin’s innovative approach to multi-stakeholder partnerships in an effort to drive early research advancements for rare diseases.

Thiola EC

• On June 28, 2019 the Company announced that the FDA approved 100 mg and 300 mg tablets of THIOLA EC, a new enteric-coated formulation of THIOLA^® (tiopronin), to be used for the treatment of cystinuria. THIOLA EC offers the potential for administration with or without food, and the ability to reduce the number of tablets necessary to manage cystinuria. THIOLA EC became available to patients in July of 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 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.
