United Therapeutics CorporationPositive phase III data for Tyvaso in IPF and ralinepag in PAH, plus progress in organ manufacturing platform.
United Therapeutics shares have gained 14% year to date, outperforming the industry's 0.8% decline, driven by clinical breakthroughs and improved long-term growth visibility. In March 2026, the company announced positive phase III data from the TETON-1 study of nebulized Tyvaso in idiopathic pulmonary fibrosis, which exceeded the strong results previously reported in TETON-2, supporting a planned FDA supplemental application. The company also reported positive phase III data for its PAH candidate ralinepag from the ADVANCE OUTCOMES study and intends to submit a new drug application in the second half of 2026. United Therapeutics is advancing its organ manufacturing platform, including FDA clearance for a phase I study of its xenotransplantation heart candidate UHeart and premarket approval for the LungFX ex-vivo lung perfusion device. However, the company faces increasing competitive pressure on its core PAH franchise, with nebulized Tyvaso sales declining after loss of exclusivity and the launch of Liquidia's Yutrepia, which posted 44% sequential sales growth in the first quarter of 2026.
