8-K: Liquidia Clears Legal Hurdles for YUTREPIA Approval Following Court Decisions

Liquidia Corporation has overcome key legal challenges, paving the way for potential FDA approval of its YUTREPIA inhalation powder for pulmonary hypertension.

Summary

• Liquidia Corporation announced that Judge Andrews of the U.S. District Court for the District of Delaware set aside an injunction that had previously blocked the FDA from approving their New Drug Application (NDA) for YUTREPIA.
• This injunction was related to a patent infringement lawsuit filed by United Therapeutics Corporation (UTHR) in 2022.
• Following this decision, the FDA is now able to consider final approval of YUTREPIA for both pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD).
• United Therapeutics has filed an appeal against the decision to set aside the injunction and has also filed two new lawsuits seeking to block the launch of YUTREPIA for PH-ILD.
• One lawsuit against the FDA was denied a motion for a temporary restraining order and preliminary injunction by Judge Bates of the U.S. District Court for the District of Columbia.
• The other lawsuit against Liquidia in Delaware District Court is still in process with briefing on a motion for a preliminary injunction ongoing.
• The regulatory exclusivity for Tyvaso in treating PH-ILD expired on March 31, 2024, removing another barrier to YUTREPIA's potential approval.

Industry Context

This announcement is significant in the pulmonary hypertension market, as YUTREPIA is a potential competitor to United Therapeutics' Tyvaso. The expiration of Tyvaso's exclusivity for PH-ILD creates an opportunity for Liquidia to enter the market.

• The convenience and dosing range of YUTREPIA, as highlighted by Liquidia, are key factors that could differentiate it from competitors.
• Other companies in the pulmonary hypertension space include Actelion (now part of Johnson & Johnson) and Bayer, which also have treatments for PAH and PH-ILD.

Legal Proceedings

• United Therapeutics has filed an appeal against the decision to set aside the injunction.
• United Therapeutics has filed two new lawsuits seeking to block the launch of YUTREPIA for PH-ILD.
