MORRISVILLE, N.C., Jan. 09, 2026 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA), a biopharmaceutical company driven by science and compassion to revolutionize care for patients with challenging respiratory and vascular diseases, today announced preliminary, unaudited full-year 2025 net product sales of YUTREPIA™ (treprostinil) inhalation powder, as well as updates on the commercial launch and the clinical pipeline. These updates will be discussed during Liquidia’s participation in the 44th Annual J.P. Morgan Healthcare Conference, taking place January 12–14, 2026, in San Francisco. The Company plans to report fully audited financial results for the year ended December 31, 2025, in February 2026.

Dr. Roger Jeffs, Liquidia’s Chief Executive Officer, said: “2025 marked a transformational year for Liquidia, with the successful commercial launch of YUTREPIA across both pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) patient populations. We are encouraged by the continued momentum in adoption, which reflects strong execution by our team and growing physician confidence in YUTREPIA as a differentiated and increasingly preferred inhaled prostacyclin option.

Looking ahead to 2026, we are excited to build on this foundation by advancing clinical programs to further differentiate YUTREPIA and L606, our extended-release treprostinil formulation, across current and potential future indications, like IPF, PPF, and PH-COPD, where there remains a significant unmet need. We believe YUTREPIA and L606 have the potential to establish a new standard for the use of inhaled prostacyclin as a critical therapeutic modality across these serious and progressive diseases.”

Pipeline Update
In 2026, Liquidia will continue investing in clinical development to further strengthen the medical evidence supporting YUTREPIA and L606, including:

• Completing the ASCENT open-label study evaluating 52 weeks of treatment in PH-ILD patients
• Initiating three (3) open-label, prospective, multicenter studies investigating the tolerability, titratability and exploratory efficacy of YUTREPIA in different patient groups, including:
  • PAH patients with inadequate response to orally delivered Uptravi® and other prostacyclin analogs
  • PH-ILD patients with inadequate response to Tyvaso® and Tyvaso DPI®
  • Idiopathic pulmonary fibrosis (IPF) and progressive pulmonary fibrosis (PPF) patients who are naïve to inhaled treprostinil treatments
• Supporting an investigator-initiated trial (IIT) evaluating YUTREPIA in combination with Winrevair® to assess the potential to reduce the need for parenteral prostacyclin therapy
• Initiating a prospective, multicenter, open-label study of YUTREPIA in patients with systemic sclerosis associated Raynaud’s phenomenon
• Enrolling PH-ILD patients into Re-Spire, the global pivotal Phase III study supporting regulatory approval of L606

About YUTREPIA™ (treprostinil) Inhalation Powder
YUTREPIA is an inhaled dry-powder formulation of treprostinil delivered through a convenient, low-effort, palm-sized device. YUTREPIA is indicated for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) to improve exercise ability. YUTREPIA was designed using Liquidia’s PRINT® Technology, which enables the development of drug particles that are precise and uniform in size, shape and composition, and that are engineered for enhanced deposition in the lung following oral inhalation. YUTREPIA was previously referred to as LIQ861 in investigational studies.

About L606 (liposomal treprostinil inhalation suspension)
L606 is an investigational, extended-release formulation of treprostinil administered twice-daily with a next-generation nebulizer. The L606 suspension uses a proprietary liposomal formulation to encapsulate treprostinil which can be released slowly at a controlled rate into the lung, enhancing drug exposure over an extended period of time. L606 is currently being evaluated in an open-label study in the United States for treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) and a global pivotal placebo-controlled efficacy study for the treatment of PH-ILD.

About Treprostinil Injection
Treprostinil Injection is the first-to-file, fully substitutable generic treprostinil for parenteral administration. Treprostinil Injection contains the same active ingredient, same strengths, same dosage form and same inactive ingredients as Remodulin® (treprostinil) and is offered to patients and physicians with the same level of service and support, but at a lower price than the branded drug. Liquidia PAH promotes the appropriate use of Treprostinil Injection for the treatment of PAH in the United States in partnership with its commercial partner, Sandoz, who holds the Abbreviated New Drug Application (ANDA) with the FDA.

About Pulmonary Arterial Hypertension (PAH)
Pulmonary arterial hypertension (PAH) is a rare, chronic, progressive disease caused by hardening and narrowing of the pulmonary arteries that can lead to right heart failure and eventually death. Currently, an estimated 45,000 patients are diagnosed and treated in the United States. There is currently no cure for PAH, so the goals of existing treatments are to alleviate symptoms, maintain or improve functional class, delay disease progression and improve quality of life.

About Pulmonary Hypertension Associated with Interstitial Lung Disease (PH-ILD)
Pulmonary hypertension (PH) associated with interstitial lung disease (ILD) includes a diverse collection of up to 150 different pulmonary diseases, including interstitial pulmonary fibrosis, chronic hypersensitivity pneumonitis, connective tissue disease-related ILD, and chronic pulmonary fibrosis with emphysema (CPFE) among others. Any level of PH in ILD patients is associated with poor 3-year survival. A current estimate of PH-ILD prevalence in the United States is greater than 60,000 patients, though actual prevalence in many of these underlying ILD diseases is not yet known due to factors including underdiagnosis and lack of approved treatments until March 2021 when inhaled treprostinil was first approved for this indication.

About Liquidia Corporation
Liquidia Corporation is a biopharmaceutical company driven by science and compassion to revolutionize care for patients with challenging respiratory and vascular diseases through precise, innovative therapies and applications of its proprietary PRINT® Technology. PRINT enabled the creation of Liquidia’s first approved product, YUTREPIA™ (treprostinil) inhalation powder for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD).  The company is also developing L606, an investigational extended-release formulation of treprostinil administered twice-daily with a next-generation nebulizer, and currently markets generic Treprostinil Injection for the treatment of PAH.
