Combined pulmonary fibrosis and emphysema

SILVER SPRING, Md. & RESEARCH TRIANGLE PARK, N.C.--( BUSINESS WIRE )--United Therapeutics Corporation (Nasdaq: UTHR ), a public benefit corporation, announced full enrollment of the TETON 1 study evaluating the use of Tyvaso® (treprostinil) inhalation solution ( nebulized Tyvaso ) for the treatment of idiopathic pulmonary fibrosis ( IPF ). The TETON 1 study enrolled 598 patients and is part of the three-study global TETON clinical trial program evaluating the use of inhaled treprostinil in IPF and a similar condition, progressive pulmonary fibrosis ( PPF ). TETON 1 is evaluating the use of inhaled treprostinil in IPF in patients in the United States and Canada. TETON 2 is evaluating the use of inhaled treprostinil in IPF in patients outside the United States and Canada. TETON PPF is evaluating the use of inhaled treprostinil in PPF in patients globally. Patients in any of the TETON program studies may use nebulized Tyvaso alone as a monotherapy or in combination with one background therapy approved for the treatment of IPF or PPF. Enrollment in TETON 2 completed in July 2024 and top-line data for that study is expected in the second half of 2025. Enrollment in TETON PPF is ongoing. “Completing enrollment in this trial brings us one step closer to potentially delivering a transformative and much needed treatment option for this vulnerable group of patients living with IPF,” said Peter Smith, Pharm. D. , Vice President, Product Development at United Therapeutics and the lead for the global TETON program. “Each of the participants in this study represents someone seeking better outcomes and improved quality of life. Their willingness to participate, along with the commitment of our investigators, moves us forward in our mission to deliver novel therapies that address significant challenges for patients and meaningfully impact the standard of care.” The TETON program in IPF and PPF was prompted by data from the INCREASE study of nebulized Tyvaso for the treatment of pulmonary hypertension associated with interstitial lung disease ( PH-ILD ), which demonstrated in a post-hoc analysis that treatment with nebulized Tyvaso resulted in significant improvements in percent predicted forced vital capacity ( FVC ) at weeks 8 and 16, with subjects having an underlying etiology of IPF showing the greatest improvement (week 8: 2.5%; p=0.038 and week 16: 3.5%; p=0.015). Further, open label extension data published in 2023 showed these improvements in FVC were sustained for at least 64 weeks. For those patients who received placebo during the INCREASE study, marked improvements in FVC were observed following transition to nebulized Tyvaso during the open-label extension study. These data points, combined with substantial preclinical evidence of antifibrotic activity of treprostinil, suggest that nebulized Tyvaso may offer a treatment option for patients with IPF and PPF. The TETON program is evaluating the use of nebulized Tyvaso, which is approved to improve exercise ability in patients with pulmonary arterial hypertension and PH-ILD. Tyvaso DPI ® (treprostinil) Inhalation Powder is not being evaluated in the TETON program, but United Therapeutics intends to seek U.S. Food and Drug Administration ( FDA ) approval to expand the Tyvaso DPI label to include IPF and PPF following completion of the TETON studies and any FDA-required bridging studies. Tyvaso Inhalation Solution and Tyvaso DPI are not approved in any jurisdiction for the treatment of IPF or PPF. If the TETON 1 and TETON 2 trials are successful, United Therapeutics intends to use the data from the studies to support a regulatory filing with the FDA to add IPF to the labeled indications for nebulized Tyvaso. In Europe, where Tyvaso is not an approved product, we plan to work with our international distributor, Grupo Ferrer Internacional, S.A., to support a marketing authorization application with the European Medicines Agency ( EMA ) for nebulized Tyvaso to treat IPF. About TETON 1 The TETON 1 study is a 598-patient, multicenter, randomized, double-blind, placebo-controlled phase 3 registration study to evaluate the safety and efficacy of nebulized Tyvaso in subjects with IPF over a 52-week period at sites in the United States and Canada. The study reached full enrollment in January 2025 and top-line data is expected in the first half of 2026. Subjects will be randomly allocated 1:1 to receive nebulized Tyvaso or placebo. All subjects will initiate nebulized Tyvaso or placebo at a dose of three breaths administered four times daily ( QID ) and will titrate to a target dosing regimen of 12 breaths QID. Study drug doses may be titrated up as tolerated, until the target dose or maximum clinically tolerated dose is achieved. The primary endpoint of the study is the change in FVC from baseline to week 52. Secondary endpoints include: (1) time to clinical worsening; (2) time to first acute exacerbation of IPF; (3) overall survival at week 52; (4) change in percent predicted FVC from baseline to week 52; and (5) change in the King’s Brief Interstitial Lung Disease questionnaire. Other data collected in the study will include the plasma N-terminal pro-brain natriuretic peptide ( NT-proBNP ) concentration, supplemental oxygen use, and lung diffusion capacity. Safety assessments include the development of adverse events, serious adverse events, vital signs, clinical laboratory parameters, and electrocardiogram parameters. About IPF Idiopathic pulmonary fibrosis, or IPF, is a scarring disease of the lungs of an unknown (idiopathic) cause and is the most common of the idiopathic interstitial pneumonias. IPF is characterized by the progressive loss of the ability of the lungs to transfer oxygen into the blood, ultimately resulting in respiratory failure and death. While the precise causes of IPF remain unknown, IPF rarely presents before age 50 and can be associated with cigarette smoking and certain genetic dispositions. In addition, some evidence suggests that gastroesophageal reflux (acid reflux, or heartburn), certain viral infections, air pollution, and some exposures in the workplace may be risk factors for IPF. According to recent research , IPF is estimated to affect between 0.33 and 4.51 people per 10,000 persons worldwide. Further, United Therapeutics estimates there are over 100,000 IPF patients in the United States alone. Just two therapies are approved in the United States to treat IPF, and studies for both therapies have shown only a reduction in the rate of forced vital capacity, or FVC, decline in IPF patients. About Tyvaso® Inhalation Solution and Tyvaso DPI® Inhalation Powder INDICATION TYVASO (treprostinil) Inhalation Solution and TYVASO DPI (treprostinil) Inhalation Powder are prostacyclin mimetics indicated for the treatment of: Pulmonary arterial hypertension (PAH; WHO Group 1) to improve exercise ability. Studies with TYVASO establishing effectiveness predominately included patients with NYHA Functional Class III symptoms and etiologies of idiopathic or heritable PAH (56%) or PAH associated with connective tissue diseases (33%). The effects diminish over the minimum recommended dosing interval of 4 hours; treatment timing can be adjusted for planned activities. While there are long-term data on use of treprostinil by other routes of administration, nearly all clinical experience with inhaled treprostinil has been on a background of an endothelin receptor antagonist (ERA) and/or a phosphodiesterase type 5 (PDE-5) inhibitor. The controlled clinical experience with TYVASO was limited to 12 weeks in duration. Pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3) to improve exercise ability. The study with TYVASO establishing effectiveness predominately included patients with etiologies of idiopathic interstitial pneumonia (IIP) (45%) inclusive of idiopathic pulmonary fibrosis (IPF), combined pulmonary fibrosis and emphysema (CPFE) (25%), and WHO Group 3 connective tissue disease (22%). IMPORTANT SAFETY INFORMATION WARNINGS AND PRECAUTIONS TYVASO and TYVASO DPI are pulmonary and systemic vasodilators. In patients with low systemic arterial pressure, either product may produce symptomatic hypotension. Both products inhibit platelet aggregation and increase the risk of bleeding. Co-administration of a cytochrome P450 (CYP) 2C8 enzyme inhibitor (e.g., gemfibrozil) may increase exposure (both Cmax and AUC) to treprostinil. Co-administration of a CYP2C8 enzyme inducer (e.g., rifampin) may decrease exposure to treprostinil. Increased exposure is likely to increase adverse events associated with treprostinil administration, whereas decreased exposure is likely to reduce clinical effectiveness. Like other inhaled prostaglandins, TYVASO and TYVASO DPI may cause acute bronchospasm. Patients with asthma or chronic obstructive pulmonary disease (COPD), or other bronchial hyperreactivity, are at increased risk for bronchospasm. Ensure that such patients are treated optimally for reactive airway disease prior to and during treatment with TYVASO and TYVASO DPI. DRUG INTERACTIONS/SPECIFIC POPULATIONS The concomitant use of either product with diuretics, antihypertensives, or other vasodilators may increase the risk of symptomatic hypotension. Human pharmacokinetic studies with an oral formulation of treprostinil (treprostinil diolamine) indicated that co-administration of the cytochrome P450 (CYP) 2C8 enzyme inhibitor, gemfibrozil, increases exposure (both Cmax and AUC) to treprostinil. Co-administration of the CYP2C8 enzyme inducer, rifampin, decreases exposure to treprostinil. It is unclear if the safety and efficacy of treprostinil by the inhalation route are altered by inhibitors or inducers of CYP2C8. Limited case reports of treprostinil use in pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes. However, pulmonary arterial hypertension is associated with an increased risk of maternal and fetal mortality. There are no data on the presence of treprostinil in human milk, the effects on the breastfed infant, or the effects on milk production. Safety and effectiveness in pediatric patients have not been established. Across clinical studies used to establish the effectiveness of TYVASO in patients with PAH and PH ILD, 268 (47.8%) patients aged 65 years and over were enrolled. The treatment effects and safety profile observed in geriatric patients were similar to younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of hepatic, renal, or cardiac dysfunction, and of concomitant diseases or other drug therapy. ADVERSE REACTIONS Pulmonary Arterial Hypertension (WHO Group 1) In a 12-week, placebo-controlled study (TRIUMPH I) of 235 patients with PAH (WHO Group 1 and nearly all NYHA Functional Class III), the most common adverse reactions seen with TYVASO in ≥4% of PAH patients and more than 3% greater than placebo were cough (54% vs 29%), headache (41% vs 23%), throat irritation/pharyngolaryngeal pain (25% vs 14%), nausea (19% vs 11%), flushing (15% vs <1%), and syncope (6% vs <1%). In addition, adverse reactions occurring in ≥4% of patients were dizziness and diarrhea. In a 3-week, open-label, single-sequence, safety and tolerability study (BREEZE) conducted in 51 patients on stable doses of TYVASO who switched to a corresponding dose of TYVASO DPI, the most commonly reported adverse events seen with TYVASO DPI in ≥4% of PAH patients during the 3-week treatment phase included cough (35.3%), headache (15.7%), dyspnea (7.8%), and nausea (5.9%). Pulmonary Hypertension Associated with ILD (WHO Group 3) In a 16-week, placebo-controlled study (INCREASE) of 326 patients with PH-ILD (WHO Group 3), adverse reactions with TYVASO were similar to the experience in studies of PAH.

DRUG INTERACTIONS/SPECIFIC POPULATIONS The concomitant use of either product with diuretics, antihypertensives, or other vasodilators may increase the risk of symptomatic hypotension. Human pharmacokinetic studies with an oral formulation of treprostinil (treprostinil diolamine) indicated that co-administration of the cytochrome P450 (CYP) 2C8 enzyme inhibitor, gemfibrozil, increases exposure (both C max and AUC) to treprostinil. Co-administration of the CYP2C8 enzyme inducer, rifampin, decreases exposure to treprostinil. It is unclear if the safety and efficacy of treprostinil by the inhalation route are altered by inhibitors or inducers of CYP2C8. Limited case reports of treprostinil use in pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes. However, pulmonary arterial hypertension is associated with an increased risk of maternal and fetal mortality. There are no data on the presence of treprostinil in human milk, the effects on the breastfed infant, or the effects on milk production. Safety and effectiveness in pediatric patients have not been established. Across clinical studies used to establish the effectiveness of TYVASO in patients with PAH and PH‑ILD, 268 (47.8%) patients aged 65 years and over were enrolled. The treatment effects and safety profile observed in geriatric patients were similar to younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of hepatic, renal, or cardiac dysfunction, and of concomitant diseases or other drug therapy. ADVERSE REACTIONS Pulmonary Arterial Hypertension (WHO Group 1) In a 12-week, placebo-controlled study (TRIUMPH I) of 235 patients with PAH (WHO Group 1 and nearly all NYHA Functional Class III), the most common adverse reactions seen with TYVASO in ≥4% of PAH patients and more than 3% greater than placebo were cough (54% vs 29%), headache (41% vs 23%), throat irritation/pharyngolaryngeal pain (25% vs 14%), nausea (19% vs 11%), flushing (15% vs <1%), and syncope (6% vs <1%). In addition, adverse reactions occurring in ≥4% of patients were dizziness and diarrhea. In a 3-week, open-label, single-sequence, safety and tolerability study (BREEZE) conducted in 51 patients on stable doses of TYVASO who switched to a corresponding dose of TYVASO DPI, the most commonly reported adverse events seen with TYVASO DPI in ≥4% of PAH patients during the 3-week treatment phase included cough (35.3%), headache (15.7%), dyspnea (7.8%), and nausea (5.9%). Pulmonary Hypertension Associated with ILD (WHO Group 3) In a 16-week, placebo-controlled study (INCREASE) of 326 patients with PH-ILD (WHO Group 3), adverse reactions with TYVASO were similar to the experience in studies of PAH.
