Business Context and Reporting Period
Liquidia Corporation filed this Form 8-K on December 1, 2023, reporting an event occurring on November 30, 2023. The filing concerns patent litigation involving YUTREPIA (treprostinil) inhalation powder and the proposed PH-ILD indication.
Material Legal and Regulatory Developments
- On November 28, 2023, the U.S. Patent and Trademark Office issued United Therapeutics Corporation U.S. Patent No. 11,826,327 (the “’327 Patent”). The patent generally covers treating pulmonary hypertension associated with interstitial lung disease through inhaled treprostinil.
- On November 30, 2023, United Therapeutics amended its patent infringement complaint in the U.S. District Court for the District of Delaware to add allegations that Liquidia infringes the ’327 Patent.
- The litigation originally involved U.S. Patent No. 10,716,793, following Liquidia’s amendment seeking to add the PH-ILD indication to the label for the tentatively approved YUTREPIA New Drug Application.
- Liquidia stated that because neither patent was issued before the original YUTREPIA NDA was filed, it believes United Therapeutics is not entitled to a statutory 30-month stay for either patent.
- Liquidia intends to vigorously defend the allegations and stated that its objective is to enable potential access to its products for patients with pulmonary arterial hypertension and PH-ILD.
Financial Metrics and Liquidity
The filing does not provide revenue, profit, cash flow, margins, debt, liquidity, or other financial metrics.
