United Therapeutics Corporation (Nasdaq: UTHR) today announced its financial results for the quarter ended September 30, 2020.

"As our core business continues to perform well, we have a solid footing to enter 2021 with several key product launches including the potential INCREASE product label expansion for Tyvaso, the Remunity Pump for Remodulin, and the Implantable System for Remodulin," said Martine Rothblatt, Ph.D., Chairman and Chief Executive Officer of United Therapeutics. "I expect these three launches will set us on the path to revenue growth in the near term."

"We are very pleased with the strong year-over-year growth for both Orenitram and Tyvaso," said Michael Benkowitz, President and Chief Operating Officer of United Therapeutics. "Our prostacyclin products are now being used by a larger number of pulmonary arterial hypertension patients in the United States than ever before, as demand has returned to pre-pandemic levels."

As of the end of the third quarter of 2020, new patient prescriptions and new patient starts, which had declined in April 2020 due to COVID-19, returned to pre-pandemic levels for our treprostinil-based products (Remodulin, Tyvaso, and Orenitram) in the United States. Our U.S. net revenues from our treprostinil-based products grew by $19.6 million for the three months ended September 30, 2020, compared to the same period in 2019. In addition, as previously disclosed, our 2019 revenues were impacted by a mistake by one of our U.S. distributors in its utilization data, which resulted in the distributor ordering more product than normal (the Excess Order). We estimate that the Excess Order generated additional revenues for Remodulin, Tyvaso, and Orenitram of approximately $13.3 million, $9.5 million, and $4.5 million, respectively, or $27.3 million in total, during the third quarter of 2019. Absent the Excess Order, our U.S. revenues for Remodulin, and our revenues for Tyvaso and Orenitram, would have grown by 1%, 28%, and 30%, respectively, in the third quarter of 2020 compared to the third quarter of 2019. We are providing these non-GAAP financial measures to show year-over-year revenue growth for these products in the absence of the Excess Order to improve investors' understanding of our financial results.

The reduction in Remodulin revenues was driven primarily by a reduction in quantities sold in Europe, which we believe resulted from generic competition and the impact of COVID-19. U.S. Remodulin revenues decreased due to the Excess Order. The growth in Tyvaso revenues resulted primarily from an increase in quantities sold, reflecting a growing number of patients being treated with Tyvaso, and price increases, partially offset by the impact of the Excess Order. The growth in Orenitram revenues resulted primarily from an increase in quantities sold, as the number of patients being treated with Orenitram grew following the update to Orenitram's labeling to reflect the FREEDOM-EV clinical trial results, partially offset by the impact of the Excess Order. The decrease in Adcirca revenues was driven by continued erosion of market share due to generic competition.

The increase in share-based compensation benefit for the three months ended September 30, 2020, as compared to the same period in 2019, was primarily due to an increase in STAP benefit driven by a 17 percent decrease in our stock price for the three months ended September 30, 2020 as compared to a 2 percent increase in our stock price for the same period in 2019.

Other expense, net. The change in other expense, net for the three months ended September 30, 2020, as compared to the same period in 2019, was primarily due to net unrealized and realized gains and losses on equity securities.

Tyvaso in pulmonary hypertension due to interstitial lung disease (PH-ILD). On February 24, 2020, we reported that the INCREASE study of Tyvaso in patients with PH-ILD met its primary endpoint of demonstrating improvement in six-minute walk distance (6MWD). Tyvaso also showed benefits across several key subgroups, including etiology of PH-ILD, disease severity, age, gender, baseline hemodynamics, and dose. Significant improvements were also observed in each of the study's secondary endpoints, including reduction in the cardiac biomarker NT-proBNP, time to first clinical worsening event, change in peak 6MWD at Week 12, and change in trough 6MWD at week 15. Treatment with Tyvaso of up to 12 breaths per session, four times daily, in the INCREASE study was well tolerated and the safety profile was consistent with previous Tyvaso studies and known prostacyclin-related adverse events.

In June 2020, we presented these and other highlights of the INCREASE data at a virtual session of the American Thoracic Society entitled "Inhaled Treprostinil in Interstitial Lung Disease-Associated Pulmonary Hypertension: The INCREASE Study." We also presented a poster at the October 2020 CHEST annual meeting detailing improvements in forced vital capacity associated with safety observations during the INCREASE study. We expect to make additional detailed results of the INCREASE study available through upcoming journal publications.

We submitted the INCREASE study results to the U.S. Food and Drug Administration (FDA) in support of an efficacy supplement to the Tyvaso new drug application (sNDA), which we expect to result in revised labeling reflecting the outcome of the INCREASE study. In August 2020, the FDA accepted the sNDA for review, which we expect will be complete in April 2021.

Remunity Pump for Remodulin. We commenced launch activities for the Remunity Pump for Remodulin, including shipping training devices to specialty pharmacies and certain health care practitioners, and entering into agreements with specialty pharmacies to purchase Remunity Pumps and accessories and to pre-fill the Remunity cartridges exclusively with Remodulin. We also confirmed with the relevant Centers for Medicare & Medicaid Services Pricing, Data Analysis, and Coding Contractor that the Remunity Pump will be treated as durable medical equipment under the Medicare Part B Durable Medical Equipment program, and will share the same billing codes and billing guidance as existing subcutaneous pumps currently used with Remodulin. We are working with large PAH medical centers to identify patient candidates for the Remunity Pump, and are training staff at these centers on how to use the product. However, the timing of our ability to commence commercial sales has been delayed due to pandemic-related issues impacting the ability of our partner, DEKA Research & Development Corp. (DEKA), to secure certain components and raw materials necessary to manufacture a continuous supply of pumps, pump disposables, and pump controllers. We are working closely with DEKA to build safety stock of these components and raw materials to a level that would allow us to withstand a significant supplier disruption without adverse impact to our patient base. We implemented this strategy due to the increasing COVID-19 infection rates observed in the United States during the second quarter of 2020, as many of the Remunity Pump component suppliers are located domestically. We are working to commence commercial sales of the Remunity Pump in the near-term, but we cannot predict the precise timing due to the factors described above, as well as the potential for additional pandemic-related constraints that physicians and patients may experience.

Trevyent. We submitted a 505(b)(1) new drug application (NDA) to the FDA for our Trevyent disposable treprostinil pump system in June 2019. In April 2020, the FDA issued a complete response letter (CRL) related to our NDA indicating that some of the deficiencies previously raised by the FDA had not yet been addressed to its satisfaction. We have one year from the date of the CRL to resubmit our NDA to the FDA, which is expected to trigger a six-month review period by the FDA. We are preparing our NDA resubmission, which we expect to file in 2021.

Implantable System for Remodulin (ISR). Developed in collaboration with Medtronic, Inc. (Medtronic), the premarket approval application (PMA) for the ISR was approved by the FDA in December 2017. However, our ability to launch the product is subject to Medtronic satisfying various conditions to its PMA approval. Medtronic continues to work toward satisfying these conditions, but in December 2019, due to FDA communications, Medtronic informed us that these conditions will not be satisfied in 2020. As such we expect a delay in the ISR launch until 2021.

RESEARCH AND DEVELOPMENT UPDATE

Our clinical studies remain open, and enrollment of new patients has resumed at select study sites for certain studies. Most of our ongoing clinical studies paused enrollment during the first quarter of 2020 due to the pandemic, but patients already enrolled in studies continue to receive the study drug and complete necessary clinical evaluations as appropriate.

The following studies have since re-opened enrollment at select sites:

• the BREEZE and pivotal pharmacokinetics studies of Treprostinil Technosphere® — while the BREEZE study remains ongoing, the pharmacokinetics study was completed in October 2020;
• the ADVANCE OUTCOMES study of ralinepag;
• the SAPPHIRE study of Aurora-GT™;
• our phase 1 study of Unexisome™ for bronchopulmonary dysplasia; and
• our initial phase 1 study of OreniPro™, which has since been completed.

We also recommenced startup activities for the ADVANCE CAPACITY study of ralinepag. While enrollment of the PERFECT study of Tyvaso in pulmonary hypertension associated with chronic obstructive pulmonary disease (PH-COPD) remains paused, we are continuing new clinical site startup activities for this study.

Although we re-opened enrollment of certain studies at a limited number of clinical trial sites, it is difficult to predict when we will be able to re-open enrollment at additional sites for these studies, and whether we will experience further disruptions as the pandemic unfolds. In addition, it is unclear what impact the pandemic may have on the timing of future studies, such as our planned TETON studies. As such, we expect that completion and data readouts for several of our ongoing and planned studies will be delayed, but we do not currently expect delays of our near-, medium-, and long-term windows for product launch plans. To mitigate potential delays, we are expanding our efforts to enter into contracts with additional clinical study sites and complete other site activation activities for certain studies where practicable so that we may rapidly resume enrollment of our clinical studies at the appropriate time.

Treprostinil Technosphere dry powder inhaler — BREEZE. The BREEZE study (NCT03950739) seeks to evaluate 45 patients on a stable dose of Tyvaso after switching to our new dry powder inhaler (DPI) form of treprostinil, which we licensed from MannKind Corporation. The primary endpoint of the study is the number of subjects with treatment-emergent adverse events after three weeks of treatment with the DPI. In October 2020, we completed a second clinical study in healthy volunteers to compare the pharmacokinetics of Treprostinil Technosphere to Tyvaso. We expect results of these two studies, combined with long-term stability studies of the DPI product, will form the basis of a 505(b)(1) NDA to the FDA.

Unituxin in relapsed/refractory neuroblastoma — ANBL1221. We are pursuing an indication expansion for Unituxin for the treatment of pediatric patients with relapsed or refractory neuroblastoma based on the results of the Children's Oncology Group's ANBL1221 study (NCT01767194). We met with the FDA in April 2020 to discuss the content needed to support a supplemental biologics license application (BLA). We are working with Children's Oncology Group to secure additional information ahead of a potential supplemental BLA. During the third quarter of 2020, we discontinued our efforts to investigate Unituxin's potential activity against adult cancers, and our efforts to develop a humanized version of Unituxin. As a result, our oncology research and development efforts are now focused primarily on scientific studies related to pediatric use of Unituxin.

Tyvaso in PH-COPD — PERFECT. The PERFECT study (NCT03496623) seeks to evaluate Tyvaso in patients with PH-COPD. In a 30-week crossover study, 136 subjects will be randomized between inhaled treprostinil and placebo for a 26-week treatment period. The primary endpoint of the study is the change in 6MWD from baseline to week 12 on active treatment compared to placebo. A contingent design for the study allows for the evaluation of 314 patients in two parallel groups.

Tyvaso in patients with chronic fibrosing interstitial lung disease (CFILD) — TETON. We are planning a new phase 3 program called TETON, which will be comprised of one or more phase 3 studies of Tyvaso in subjects with various forms of chronic fibrosing interstitial lung diseases, which includes patients with idiopathic interstitial pneumonias, chronic hypersensitivity pneumonitis, and environmental/occupational lung disease. The first TETON study will enroll subjects with idiopathic pulmonary fibrosis. The primary endpoint of this study is planned to be the change from baseline to week 52 in absolute forced vital capacity. This program was prompted by data from the INCREASE study, which demonstrated improvements in certain key parameters of lung function in pulmonary hypertension patients with fibrotic lung disease (improved forced vital capacity and reduced exacerbations of underlying lung disease).

Ralinepag phase 3 development program — ADVANCE CAPACITY and ADVANCE OUTCOMES. We have two ongoing phase 3 clinical studies to support the potential registration of oral ralinepag for PAH.

• ADVANCE CAPACITY. The phase 3 ADVANCE CAPACITY study (NCT04084678) seeks to evaluate 193 subjects with PAH, randomized between oral ralinepag and placebo at a 2:1 ratio, along with PAH background therapy, for 28 weeks. The primary endpoint of the study is the change from baseline to week 28 in peak oxygen consumption assessed by cardiopulmonary exercise testing.
• ADVANCE OUTCOMES. The phase 3 ADVANCE OUTCOMES study (NCT03626688) seeks to evaluate approximately 700 PAH patients, randomized 1:1 between oral ralinepag and placebo along with background therapy. The primary endpoint is the time from randomization to the first adjudicated protocol-defined clinical worsening event.

Autologous cell therapy for PAH — SAPPHIRE. Conducted by our Canadian affiliate Northern Therapeutics, Inc., the phase 2 SAPPHIRE study seeks to evaluate the use of autologous endothelial progenitor cells (EPCs) genetically engineered to express endothelial nitric oxide synthase in patients with PAH taking conventional PAH treatments. The study seeks to enroll 45 PAH patients in one of three arms: (i) placebo for six months followed by autologous EPCs for six months; (ii) autologous EPCs for six months followed by placebo for six months; and (iii) autologous EPCs for 12 months. The primary endpoint is the change in 6MWD from baseline to month six.

LNG01 in interstitial lung disease. During the third quarter of 2020, we discontinued the development of LNG01, a Wnt pathway inhibitor formerly known as SM04646, and terminated the related license agreement with Samumed LLC (Samumed) effective November 2020. In accordance with the terms of the license agreement, this development program will revert to Samumed.
