• Tyvaso TETON-1 Study Success

  The Phase 3 TETON-1 clinical study of Tyvaso (treprostinil) Inhalation Solution in idiopathic pulmonary fibrosis (IPF) patients met its primary endpoint, demonstrating superior improvement in forced vital capacity (FVC) over placebo (130.1 mL, p <0.0001).

• Reduced Clinical Worsening

  Nebulized Tyvaso also achieved statistical significance in reducing the risk of clinical worsening and showed numerical improvements in other key secondary endpoints, including time to first acute exacerbation of IPF.

• Integrated Data Reinforces Efficacy

  Integrated analyses of both TETON-1 and TETON-2 studies confirmed statistically significant treatment effects across primary and most secondary efficacy endpoints, reinforcing the robustness of the results.

• Priority sNDA Submission Planned

  United Therapeutics plans to seek priority review for a supplemental New Drug Application (sNDA) with the FDA by the end of this summer to add IPF to Tyvaso's labeled indications, leveraging the strong clinical data.

This 8-K reports highly positive Phase 3 clinical trial results for Tyvaso in idiopathic pulmonary fibrosis (IPF), a severe lung disease with limited treatment options. The TETON-1 study met its primary endpoint with strong statistical significance, showing a clinically meaningful improvement in forced vital capacity and reduced risk of clinical worsening. This success, combined with previous TETON-2 results, positions Tyvaso as a potential "game changer" for IPF patients and significantly expands its market opportunity. The company's plan to seek priority review for a supplemental New Drug Application (sNDA) by the end of summer indicates an accelerated path to potential market approval, which could drive substantial future revenue growth for United Therapeutics.
