BARCONA STUDY ENROLLMENT ONGOING

PLANO, Texas, Nov. 09, 2020 (GLOBE NEWSWIRE) — Reata Pharmaceuticals, Inc. (Nasdaq: RETA) (“Reata,” the “Company,” or “we”), a clinical-stage biopharmaceutical company, today announced financial results for the quarter ended September 30, 2020, and provided an update on the Company’s business operations and clinical development programs.

Clinical and Regulatory Update

Bardoxolone Methyl (“Bardoxolone”) for Alport Syndrome

In a separate press release issued today, we announced that the Phase 3 CARDINAL study of bardoxolone in patients with chronic kidney disease (“CKD”) caused by Alport syndrome met its primary and key secondary endpoints at the end of Year 2. At Week 100, in the intent-to-treat (“ITT”) population, which included eGFR values for patients who remained on or discontinued study drug, patients treated with bardoxolone had a statistically significant improvement compared to placebo in mean change from baseline in estimated glomerular filtration rate (“eGFR”) of 7.7 mL/min/1.73 m² (p=0.0005). In the modified ITT (“mITT”) analysis, which assessed the effect of receiving treatment by excluding values after patients discontinued treatment, patients treated with bardoxolone had a statistically significant improvement compared to placebo in mean change from baseline in eGFR at Week 100 of 11.3 mL/min/1.73 m² (p<0.0001). At Week 104 (four-weeks after last dose in second year of treatment), patients in the ITT population treated with bardoxolone had a statistically significant improvement compared to placebo in mean change from baseline in eGFR of 4.3 mL/min/1.73 m² (p=0.023). Bardoxolone treatment was generally reported to be well-tolerated. In the long-term extension study, in the 14 patients who completed three years of treatment, bardoxolone treatment resulted in a mean increase from baseline in eGFR of 11.0 mL/min/1.73 m².

Based on these positive results and following a recently completed pre-New Drug Application (“NDA”) meeting with the U.S. Food and Drug Administration (“FDA”), the Company plans to proceed with the submission of an NDA for full marketing approval in the United States in the first quarter of 2021. We will also continue preparations to file for marketing approval in Europe.

The press release can be found at the Investors section of our website at www.reatapharma.com.

Omaveloxolone for Friedreich’s Ataxia (“FA”)

As previously announced, at a Type C meeting, the FDA provided us guidance that although it does not have any concerns with the reliability of the modified Friedreich’s Ataxia Rating Scale (“mFARS”) primary endpoint results from the registrational Part 2 of the MOXIe trial (“Part 2”) of omaveloxolone in FA patients, it was not convinced that the results from Part 2 support a single study approval. The FDA stated that we will need to conduct a second pivotal trial that confirms the mFARS results of Part 2 with a similar magnitude of effect. As an alternative, Reata proposed a second study (“the Baseline-Controlled Study”, previously called the crossover study) in which patients serve as their own controls, and changes in mFARS during the pre-treatment period in either Part 1 or Part 2 of the MOXIe study are compared to changes in mFARS during the treatment period in the open-label extension study (“MOXIe Extension”). The design of the Baseline-Controlled Study was discussed and agreed upon by external experts and Reata, and the statistical analysis plan was submitted to the FDA prior to conducting the analysis contemplated by the proposed plan. The FDA acknowledged it would consider the study design but, to date, it has not provided comments on the study design.

The Baseline-Controlled Study met its primary endpoint of paired difference in annualized mFARS slope with a statistically significant 3.76 point improvement (p=0.0022) between the treatment and pre-treatment periods in the primary analysis population. Further, all sensitivity analyses of the primary analysis showed a significant treatment effect. Thus, we believe that the results of the Baseline-Controlled Study support the positive mFARS results of Part 2 and provide additional evidence of the effectiveness of omaveloxolone in FA.

We completed the Baseline-Controlled Study in October 2020 and provided the results to the FDA. The FDA confirmed that it will review the study results and may request a meeting with us to discuss the conclusions of its review. If the FDA views these results as sufficient to increase the persuasiveness of data from Part 2, our plan would be to submit an NDA in mid-2021. However, there can be no assurance that the FDA will accept the design of the Baseline-Controlled Study or view these results as sufficient, in which case we will determine next steps, including whether it is feasible to conduct a second pivotal study in patients with FA as previously suggested by the FDA. At present, we plan to pursue marketing approval outside of the United States and work has commenced on preparations to file for marketing approval in Europe.

Clinical Development Update

FALCON Phase 3 Study of Bardoxolone in Autosomal Dominant Polycystic Kidney Disease (“ADPKD”)

We began to lift the screening hold in FALCON in June 2020, and currently, most sites are able to screen and randomize patients. The measures we implemented to the conduct of FALCON in response to COVID-19 have been effective, and we anticipate no meaningful impact on data integrity due to COVID-19.

BARCONA Investigator-Sponsored Trial (“IST”) of Bardoxolone in Patients with COVID-19

The Phase 2 BARCONA IST study of bardoxolone in patients with COVID-19 is a randomized, double-blind trial that will enroll approximately 40 patients with a primary endpoint of safety and treatment duration of up to 29 days in hospitalized patients. To further mitigate any safety risk, the trial was designed to pause after the enrollment of five patients to assess safety. The first five patients were enrolled, and the Executive Steering Committee reviewed the blinded safety data and decided to continue with enrollment. As with all trials conducted at New York University’s Grossman School of Medicine (“NYU”), the trial will be overseen by a Data Safety Monitoring Board that meets every other week. Any further enrollment in a potential Phase 3 trial will be gated based on an assessment of Phase 2 safety and activity, as well as feasibility of conducting a Phase 3 trial.

Recent FA Data Presentations and Publications

In September 2020, additional data analyses from the MOXIe Part 2 study were presented at the American Academy of Neurology’s Emerging Science conference and the FARA 2020 Biomarker & Clinical Endpoint Meeting by Dr. David Lynch, M.D., Ph.D.

In October 2020, the results from the MOXIe Part 2 study evaluating the efficacy and safety of omaveloxolone in patients with FA were published in the journal Annals of Neurology.

Third Quarter Financial Highlights

Cash and Cash Equivalents

At September 30, 2020, we had cash and cash equivalents of $578.3 million.

Collaboration Revenue

Collaboration revenue was $1.4 million in the third quarter of 2020, as compared to $8.2 million for the same period of the year prior. Collaboration revenue was $5.8 million for the nine-month period ended September 30, 2020, as compared to $23.8 million for the same period of the year prior.

GAAP and Non-GAAP Research and Development (“R&D”) Expenses

R&D expenses according to generally accepted accounting principles in the U.S. (“GAAP”) were $37.2 million for the third quarter of 2020, as compared to $32.3 million for the same period of the year prior.

Non-GAAP R&D expenses were $32.9 million for the third quarter of 2020, as compared to $30.4 million for the same period of the year prior.¹

GAAP and Non-GAAP General and Administrative (“G&A”) Expenses

GAAP G&A expenses were $18.3 million for the third quarter of 2020, as compared to $14.3 million for the same period of the year prior.

Non-GAAP G&A expenses were $11.0 million for the third quarter of 2020, as compared to $10.8 million for the same period of the year prior.¹

GAAP and Non-GAAP Net Loss

The GAAP net loss for the third quarter of 2020 was $65.5 million, or $1.94 per share, on both a basic and diluted basis, as compared to a GAAP net loss of $39.7 million, or $1.32 per share, on both a basic and diluted basis, for the same period of the year prior.

The increase in GAAP net loss for the third quarter of 2020 is driven primarily by decreased Collaboration Revenue related to AbbVie since the reacquisition of our licensing rights, increased research and development expenses due to manufacturing, preclinical, and regulatory activities, increased personnel and stock-based compensation costs to support the growth in our development activities, and non-cash interest expense recognized under our liability related to sale of future royalties.

The non-GAAP net loss for the third quarter of 2020 was $44.3 million, or $1.31 per share on both a basic and diluted basis, as compared to a non-GAAP net loss of $34.3 million, or $1.14 per share, on both a basic and diluted basis, for the same period of the year prior.¹

Reiterates Cash Guidance

The Company reiterated that it expects existing cash and cash equivalents will be sufficient to enable it to fund operations through the end of 2023.

__________________

¹ See “Use of Non-GAAP Financial Measures” below for a description of non-GAAP financial measures and a reconciliation between GAAP and non-GAAP R&D expenses, GAAP and non-GAAP G&A expenses, and GAAP and non-GAAP net loss, respectively, appearing later in the press release.

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures, including non-GAAP R&D expenses, non-GAAP G&A expenses, non-GAAP operating expenses, non-GAAP net loss and non-GAAP net loss per common share – basic and diluted. These measures are not in accordance with, or an alternative to, GAAP, and may be different from non-GAAP financial measures used by other companies.

The Company defines non-GAAP R&D expenses as GAAP R&D expenses less stock-based compensation expense; non-GAAP G&A expenses as GAAP G&A expenses less stock-based compensation expense; non-GAAP operating expenses as GAAP operating expenses less stock-based compensation expense; non-GAAP net loss as GAAP net loss plus stock-based compensation expense, loss on extinguishment of debt, and non-cash interest expense from liability related to sale of future royalties less gain on lease termination; and non-GAAP net loss per common share – basic and diluted as GAAP net loss per common share – basic and diluted plus stock-based compensation expense, loss on extinguishment of debt, and non-cash interest expense from liability related to sale of future royalties less gain on lease termination. During the three and nine months ended September 30, 2020 and 2019, the Company did not incur any reacquired license rights expense; therefore, this expense is not included in the reconciliations below for the measures for non-GAAP operating expenses, non-GAAP net loss, and non-GAAP net loss per common share – basic and diluted for these periods. The Company has excluded the impact of stock-based compensation expense, which may fluctuate from period to period based on factors including the variability associated with performance-based grants for stock options and restricted stock units and changes in the Company’s stock price, which impacts the fair value of these awards. The Company has excluded the impact of loss on extinguishment of debt in connection with the Term Loan payoff and gain on lease termination as they are non-recurring transactions, that make it difficult to compare its results to peer companies who also provide non-GAAP disclosures. The Company has excluded the impact of accreted non-cash interest expense from liability related to sale of future royalties as it may be calculated differently from, and therefore may not be comparable to, peer companies who also provide non-GAAP disclosures. The Company has excluded the impact of stock-based compensation expense, loss on extinguishment of debt, non-cash interest expense from liability related to sale of future royalties, gain on lease termination, and reacquired license rights expense because the Company believes its impact makes it difficult to compare its results to prior periods and anticipated future periods.

Because management believes certain items, such as stock-based compensation expense, loss on extinguishment of debt, non-cash interest expense from liability related to sales of future royalties, gain on lease termination, and reacquired license rights expense can distort the trends associated with the Company’s ongoing performance, the following measures are often provided, excluding special items, and utilized by the Company’s management, analysts, and investors to enhance consistency and comparability of year-over-year results, as well as to industry trends, and to provide a basis for evaluating operating results in future periods: non-GAAP net loss; non-GAAP net loss per common share – basic and diluted; non-GAAP R&D expenses; non-GAAP G&A expenses; and non-GAAP operating expenses.

The Company believes the presentation of these non-GAAP financial measures provides useful information to management and investors regarding the Company’s financial condition and results of operations. When GAAP financial measures are viewed in conjunction with these non-GAAP financial measures, investors are provided with a more meaningful understanding of the Company’s ongoing operating performance and are better able to compare the Company’s performance between periods. In addition, these non-GAAP financial measures are among those indicators the Company uses as a basis for evaluating performance, allocating resources and planning and forecasting future periods. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between these non-GAAP measures and the most directly comparable GAAP measures is provided later in this press release.

About the Off-Treatment eGFR Endpoint

CKD is characterized by a progressive worsening in the rate at which the kidney filters waste products from the blood called the glomerular filtration rate or GFR. When GFR falls too low, patients require dialysis or a kidney transplant to survive. Dialysis leads to a reduced quality of life and increases the likelihood of serious and life-threatening complications. The five-year survival rate for hemodialysis patients is only approximately 42%. eGFR is an estimate of GFR that nephrologists use to track the decline in kidney function and progression of CKD.

In rare forms of CKD, the FDA has accepted the off-treatment endpoint as the basis for approval. Withdrawal of drug after long-term treatment provides evidence whether a drug either protected or harmed the kidney during treatment. If off-treatment changes in eGFR are higher than placebo, this is evidence that the drug protected the kidney during treatment, and, if off-treatment changes in eGFR are lower than placebo, this is evidence that the drug harmed the kidney during treatment. An off-treatment eGFR benefit relative to placebo provides evidence that drug treatment may delay kidney failure.

About Alport Syndrome

Alport syndrome is a rare, genetic form of CKD caused by mutations in the genes encoding type IV collagen, which is a major structural component of the glomerular basement membrane in the kidney. The kidneys of patients with Alport syndrome progressively lose the capacity to filter waste products out of the blood, which can lead to end-stage kidney disease and the need for chronic dialysis treatment or a kidney transplant. Alport syndrome affects both children and adults. In patients with the most severe forms of the disease, approximately 50% progress to dialysis by age 25, 90% by age 40, and nearly 100% by age 60. According to the Alport Syndrome Foundation, Alport syndrome affects approximately 30,000 to 60,000 people in the United States. There are currently no approved therapies to treat CKD caused by Alport syndrome.

About Bardoxolone Methyl

Bardoxolone methyl is an investigational, oral, once-daily activator of Nrf2, a transcription factor that induces molecular pathways that promote the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling. The FDA has granted Orphan Drug designation to bardoxolone for the treatment of Alport syndrome. The European Commission has granted Orphan Drug designation in Europe to bardoxolone for the treatment of Alport syndrome.

In addition to the CARDINAL Phase 3 study, bardoxolone is currently being studied in FALCON, a Phase 3 study for the treatment of autosomal dominant polycystic kidney disease, AYAME, a Phase 3 study for the treatment of diabetic kidney disease that is being conducted by our licensee, Kyowa Kirin Co., Ltd., in Japan, and BARCONA, an investigator-sponsored Phase 2 study for the treatment in patients suffering from COVID-19 conducted by researchers at NYU Grossman School of Medicine. Bardoxolone treatment has produced positive results in Phase 2 studies in patients with IgA nephropathy, focal segmental glomerulosclerosis, and CKD associated with type 1 diabetes.

About Friedreich’s Ataxia

FA is a rare, inherited, life-shortening, debilitating, and degenerative neuromuscular disorder, which is normally diagnosed during adolescence. FA is typically caused by a trinucleotide repeat expansion in the first intron of the frataxin gene, which encodes the mitochondrial protein frataxin. Pathogenic repeat expansions can lead to impaired transcription and reduced frataxin expression, which can lead to mitochondrial iron overload and poor cellular iron regulation, increased sensitivity to oxidative stress, and impaired mitochondrial ATP production. Patients with FA experience initial symptoms in childhood, including progressive loss of coordination, muscle weakness, and fatigue, commonly resulting in motor incapacitation, with patients requiring a wheelchair by their teens or early 20s. FA patients may also experience visual impairment, hearing loss, diabetes, and cardiomyopathy. Based on literature and proprietary research, we believe FA affects approximately 5,000 children and adults in the United States and 22,000 individuals globally. There are currently no approved therapies for the treatment of FA.

About Omaveloxolone

Omaveloxolone is an investigational, oral, once-daily activator of Nrf2, a transcription factor that induces molecular pathways that promote the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling. The FDA has granted Orphan Drug designation to omaveloxolone for the treatment of Friedreich’s ataxia. The European Commission has granted Orphan Drug designation in Europe to omaveloxolone for the treatment of Friedreich’s ataxia.
