United Therapeutics Corporation

Company Overview

Business Model: United Therapeutics Corporation operates as a biotechnology public benefit corporation focused on developing and commercializing innovative products for chronic and life-threatening conditions, primarily pulmonary arterial hypertension (PAH) and other life-threatening diseases. Its mission is to find a cure for PAH and other life-threatening diseases, and to create an unlimited supply of manufactured organs and organ alternatives for transplantation. The company generates revenue through the sale of its commercial therapies, including Tyvaso DPI (treprostinil) Inhalation Powder, Tyvaso (treprostinil) Inhalation Solution (nebulized Tyvaso), Remodulin (treprostinil) Injection, Orenitram (treprostinil) Extended-Release Tablets, and Adcirca (tadalafil) Tablets, all for PAH and/or pulmonary hypertension associated with interstitial lung disease (PH-ILD). It also markets Unituxin (dinutuximab) Injection for high-risk neuroblastoma and provides ex vivo lung perfusion services.

Market Position: United Therapeutics Corporation holds a significant position in the PAH and PH-ILD markets, with Tyvaso DPI and nebulized Tyvaso being the only FDA-approved inhaled therapies for PH-ILD. Orenitram is the only FDA-approved, orally-administered prostacyclin analogue that is titratable to a maximum tolerated dose without a dose ceiling. The company's treprostinil-based products (Tyvaso DPI, nebulized Tyvaso, Remodulin, and Orenitram) comprise the vast majority of its revenues. It is also a pioneer in manufactured organs and organ alternatives, with the first FDA-cleared Investigational New Drug application (IND) for its UKidney product, enabling human clinical trials for a gene-edited porcine kidney.
