Company Description
United Therapeutics Corporation (NASDAQ: UTHR) is a biotechnology and pharmaceutical company focused on developing and commercializing therapies for serious cardiopulmonary and other life-threatening conditions. Classified under pharmaceutical preparation manufacturing, United Therapeutics has built a portfolio of therapies for pulmonary arterial hypertension (PAH) and related diseases, and is also advancing technologies intended to expand the availability of transplantable organs.
According to company disclosures, United Therapeutics markets and sells therapies in the United States for PAH that largely target the prostacyclin pathway. Many of these treatments are based on the molecule treprostinil. The company’s commercial PAH therapies include Tyvaso DPI (treprostinil) Inhalation Powder, Remodulin Injection, Orenitram (treprostinil) Extended-Release Tablets, Adcirca (tadalafil) Tablets, and Unituxin. These products reflect a strategy of addressing rare, progressive cardiopulmonary diseases with specialized drug formulations and delivery systems.
Focus on pulmonary arterial hypertension and lung disease
United Therapeutics states that its therapies for PAH focus on the prostacyclin pathway, a key signaling pathway in pulmonary vascular biology. The company has developed multiple formulations of treprostinil, including inhaled, oral, and injectable forms, to address different clinical needs. Tyvaso (treprostinil) Inhalation Solution is indicated for the treatment of PAH (WHO Group 1) to improve exercise ability and for pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3) to improve exercise ability, based on controlled clinical studies described in company materials.
The company is also developing new indications and delivery devices for existing products and new products to treat PAH and other conditions. For example, United Therapeutics has reported results from the TETON-2 phase 3 study of nebulized Tyvaso in idiopathic pulmonary fibrosis (IPF), a fibrotic lung disease. The TETON-2 study met its primary efficacy endpoint of improvement in absolute forced vital capacity relative to placebo and showed statistically significant improvements in several secondary endpoints, according to company announcements. These data are intended to support a supplemental New Drug Application to add IPF as an indication for nebulized Tyvaso.
Organ manufacturing and xenotransplantation initiatives
Beyond pharmaceuticals, United Therapeutics describes a public benefit purpose that includes developing technologies to expand the availability of transplantable organs. In line with this purpose, the company has disclosed projects in manufactured organs and organ alternatives. One example is the UKidney program, an investigational xenokidney derived from a genetically modified pig. In the EXPAND clinical trial, United Therapeutics reported the first clinical xenotransplantation of UKidney in a patient with end-stage renal disease, conducted at NYU Langone Health.
The EXPAND study is described as a multicenter, open-label, safety and efficacy study designed as a combination phase 1/2/3 trial to evaluate UKidney in patients with end-stage renal disease. The trial includes cohort-based enrollment, long-term follow-up for UKidney function and zoonotic infections, and predefined safety and efficacy endpoints such as participant survival, graft survival, renal function measures, and quality of life. This program illustrates the company’s effort to address organ shortages through xenotransplantation technologies.
Public benefit corporation structure and mission
United Therapeutics emphasizes that it is the first publicly traded biotech or pharmaceutical company to take the form of a public benefit corporation (PBC). The company repeatedly describes its public benefit purpose as providing a brighter future for patients through (a) the development of novel pharmaceutical therapies and (b) technologies that expand the availability of transplantable organs. In its public statements, United Therapeutics characterizes its culture as enthusiastic, creative, persistent, and "bold and unconventional," summarizing its ethos as "we have fun, we do good."
This PBC structure is central to how the company presents its mission and stakeholder focus. It signals an explicit commitment, alongside shareholder returns, to patient-oriented and societal objectives, particularly in rare diseases and organ transplantation.
Research, clinical programs, and portfolio development
United Therapeutics reports ongoing investment in research and development across both commercial and pipeline assets. Company communications describe increased expenditures related to manufactured organ and organ alternative projects, as well as milestone payments for drug delivery technologies. Clinical programs highlighted by the company include:
- TETON-2: A 597-patient, multicenter, randomized, double-blind, placebo-controlled phase 3 study of nebulized Tyvaso in IPF over 52 weeks, with primary and secondary endpoints focused on lung function, clinical worsening, exacerbations, survival, and quality of life.
- TETON-1 and TETON-OLE: A related phase 3 trial and open-label extension evaluating nebulized Tyvaso in fibrotic lung disease, including long-term safety and tolerability.
- PHINDER: A study focused on pulmonary hypertension screening in patients with interstitial lung disease, including analyses of echocardiographic features and imaging findings.
- Ralinepag: Evaluation of ralinepag for PAH in an open-label extension study, with interim data presented at scientific meetings.
- EXPAND: The multicenter, open-label UKidney xenotransplantation trial in end-stage renal disease.
United Therapeutics frequently presents clinical data at major scientific and medical conferences, including the European Respiratory Society Congress, the CHEST Annual Meeting, and other specialty forums. These activities underscore the company’s focus on pulmonary hypertension, interstitial lung disease, and transplant-related research.
