In September 2025, BioWorld recorded 230 clinical trial updates spanning phases I through III, up sharply from 95 in August, 140 in July and just below 254 in June. Among these, 22 phase III trials reported positive outcomes, while four ended in failure and another three produced mixed results.

Puretech Health plc’s rollout May 20 of more phase IIb data with deupirfenidone (LYT-100) in idiopathic pulmonary fibrosis (IPF) perked optimism for that compound – a deuterated form of p38 MAP kinase inhibitor pirfenidone – as well as others in the busy therapeutic space.
Insmed Inc.’s chair and CEO, Will Lewis, called the phase IIb trial of TPIP in pulmonary arterial hypertension a “clear and unequivocal success,” with analysts and investors wholeheartedly agreeing, as the company’s shares surged 28.7% June 10.
Despite the U.S. FDA’s tentative approval of Liquidia Corp.’s Yutrepia (treprostinil) for treating pulmonary arterial hypertension and pulmonary hypertension associated with interstitial lung disease, the company is stuck in the starting gate. Liquidia said it disagrees with the agency’s stance of simultaneously granting regulatory exclusivity in both indications to United Therapeutics Corp.’s powdered formulation of treprostinil, branded Tyvaso, until May 23, 2025. That means full approval for the inhalation powder won’t come until after that date and neither will a Yutrepia launch.
Instead of inter partes review (IPR) being a streamlined alternative to costly patent litigation as intended, a precedential decision by the U.S. Circuit Court of Appeals for the Federal Circuit could make appeals of IPR decisions, regardless of their merits, another way to delay competition.
The U.S. Court of Appeals for the Federal Circuit declined an invitation in United Therapeutics Corp. v. Liquidia Technologies Inc. to expand the enablement and written description bar for biopharma claims into the realm of regulatory approval.
A new FDA approval for United Therapeutics Corp.'s prostacyclin analogue, Tyvaso (treprostinil), has expanded its label to include the treatment of pulmonary hypertension associated with interstitial lung disease to improve exercise ability. The regulatory win could double the number of patients taking the medicine by the end of 2022, barring any COVID-19-related delay, said company President and CEO Michael Benkowitz.
The FDA’s bright line between orphan designation and exclusivity was erased, again, Monday for some drugs when the U.S. Court of Appeals for the District of Columbia denied the agency an en banc rehearing of Eagle Pharmaceuticals Inc. v. Alex Azar.
