Press Release

MORRISVILLE, N.C., May 13, 2024 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA) today reported financial results for the first quarter ended March 31, 2024. The company will host a webcast at 8:30 a.m. ET on May 14, 2024 to discuss the financial results and provide a corporate update.

Dr. Roger Jeffs, Liquidia’s chief executive officer, said: “We continue to vigorously pursue final agency action for YUTREPIA’s approval for pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). And as we have shown, we will remain relentless in the defense of our freedom to go to market despite the myriad of legal filings by our competitor. At our core is our steadfast commitment to deliver YUTREPIA to patients with PAH and PH-ILD. We feel YUTREPIA can provide an important and differentiated alternative to address lingering unmet needs that continue to limit the optimal delivery of inhaled treprostinil.”

Corporate Updates

Removed all legal barriers for FDA to issue final action on the amended NDA for YUTREPIA. As of April 1, 2024, there is no further legal impediment preventing the U.S. Food and Drug Administration (FDA) from granting final approval of YUTREPIA for both PAH and PH-ILD. In late March 2024, Judge Andrews set aside the injunction issued in the original Hatch-Waxman litigation that had prevented FDA approval of the NDA for YUTREPIA. In addition, the FDA regulatory exclusivity granted to Tyvaso® for the treatment of PH-ILD expired on March 31, 2024.

Progressing the ASCENT study of YUTREPIA in PH-ILD. The company continues to enroll up to 60 subjects into the ASCENT study, an open-label prospective multicenter study to evaluate safety and tolerability of YUTREPIA in patients diagnosed with PH-ILD. Patients to date have titrated to known therapeutics doses of at least 79.5 mcg and up to 318 mcg, a range comparable to 9 to 36 breaths of Tyvaso. The company intends to present data at medical conferences later in the year.

Continuing to treat PAH and PH-ILD patients with L606. The sustained-release liposomal formulation of treprostinil is being evaluated in an open-label study in PH-ILD and PAH patients. To date, patients have safely titrated to doses up to 378 mcg administered twice daily, a dosage that would be comparable to 26 to 28 breath equivalents of Tyvaso administered four times daily. Liquidia will share additional safety and dosing data from the on-going L606 study in a poster presentation at the American Thoracic Society 2024 International Conference in San Diego on May 22, 2024.

Awaiting ruling from District Court on preliminary injunction in new patent infringement lawsuit filed by United Therapeutics. United Therapeutics filed a new patent infringement lawsuit against the company in Delaware District Court (Case No. 1:23-cv-00975-RGA) alleging that YUTREPIA infringes U.S. Patent No. 11,826,327 (‘327 patent), which issued in November 2023. UTHR has filed a motion for preliminary injunction to block Liquidia from launching YUTREPIA for PH-ILD. Judge Andrews heard oral arguments from both parties regarding the motion for preliminary injunction on April 23, 2024, and the matter is fully briefed. The parties are awaiting the Court’s decision.  

Court denied United Therapeutics’ Request for Injunctive Relief in Lawsuit Against FDA. UTHR filed a separate lawsuit against FDA in the U.S. District Court for the District of Columbia (Case No. 1:24-cv00484-JDB), and a motion for a temporary restraining order and preliminary injunction, seeking to require FDA to reject the amendment to Liquidia’s NDA to add PH-ILD to the label for YUTREPIA. Judge Bates, who is presiding over this lawsuit, denied UTHR’s motion on the basis that the FDA had not yet taken final agency action with respect to Liquidia’s NDA. However, the Court has ordered that FDA provide the Court and the parties with at least three business days’ advance notice prior to issuance of any decision on Liquidia’s NDA. The FDA has since filed a motion to dismiss the lawsuit, and briefing on the motion to dismiss is in progress.

First Quarter 2024 Financial Results

Cash and cash equivalents totaled $157.9 as of March 31, 2024, compared to $83.7 million as of December 31, 2023. In the first week of January, Liquidia closed two transactions that brought an additional $100 million of gross proceeds into the company. Liquidia and an affiliate of Patient Square Capital entered into a common stock purchase agreement for the private placement of common stock that yielded gross proceeds of $75.0 million. That same week, HealthCare Royalty Partners (HCRx) and Liquidia entered a fourth amendment to the Revenue Interest Financing Agreement (RIFA) to fund an additional $25.0 million. HCRx has now invested $67.5 million in non-dilutive capital from the $100 million originally contemplated from four tranches under the RIFA.

Revenue was $3.0 million for the three months ended March 31, 2024, compared to $4.5 million for the three months ended March 31, 2023. Revenue related primarily to the promotion agreement with Sandoz pursuant to which we share profits from the sale of Treprostinil Injection in the United States (the Promotion Agreement). The decrease from the prior year was primarily due to favorable gross-to-net rebate adjustments recorded in the prior year and the impact of lower sales quantities in the current year as compared to the same period in the prior year.

Cost of revenue was $1.5 million for the three months ended March 31, 2024, compared to $0.7 million for the three months ended March 31, 2023. Cost of revenue related to the Promotion Agreement. The increase from the prior year was primarily due to our sales force expansion during the fourth quarter of 2023.

Research and development expenses were $10.1 million for the three months ended March 31, 2024, compared to $5.3 million for the three months ended March 31, 2023. The increase of $4.8 million or 91% was primarily due to a $2.0 million increase in personnel expenses (including stock-based compensation) related to higher headcount, and a $1.7 million increase in clinical expenses related to our L606 program. Additionally, there was a $1.3 million increase in expenses related to our YUTREPIA program driven by higher clinical and supply expenses related to our ASCENT study, which was initiated in the second half of 2023.

General and administrative expenses were $20.2 million for the three months ended March 31, 2024, compared to $7.8 million for the three months ended March 31, 2023. The increase of $12.4 million or 160% was primarily due to a $3.1 million increase in legal fees related to our ongoing YUTREPIA-related litigation, a $5.9 million increase in personnel expenses (including stock-based compensation), and a $2.2 million increase in commercial and consulting expenses in preparation for the potential commercialization of YUTREPIA.

Total other expenses, net was $12.1 for the three months ended March 31, 2024, compared with $2.5 million for the three months ended March 31, 2023. The increase of $9.6 million was primarily due to driven by a $9.2 million increase in loss on extinguishment of debt resulting from the Fourth Amendment to the RIFA, which was executed in January 2024, and a $1.4 million increase in interest expense attributable to the higher borrowings under the RIFA compared to the prior year. These increases were offset by a $1.0 million increase in interest income attributable to higher money market balances.

Net loss for the three months ended March 31, 2024, was $40.9 million or $0.54 per basic and diluted share, compared to a net loss of $11.7 million, or $0.18 per basic and diluted share, for the three-month ended March 31, 2023.   

About YUTREPIA™ (treprostinil) Inhalation Powder
YUTREPIA is an investigational, inhaled dry-powder formulation of treprostinil delivered through a convenient, low-effort, palm-sized device. The FDA previously issued tentative approval of YUTREPIA for the PAH indication in November 2021. In July 2023, Liquidia filed an amendment to its New Drug Application for YUTREPIA, seeking to add PH-ILD to the label. 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. Liquidia has completed INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil, an open-label, multi-center phase 3 clinical study of YUTREPIA in patients diagnosed with PAH who are naïve to inhaled treprostinil or who are transitioning from Tyvaso® (nebulized treprostinil). YUTREPIA is currently being studied in the ASCENT trial, an Open-Label Prospective Multicenter Study to Evaluate Safety and Tolerability of Dry Powder Inhaled Treprostinil in Pulmonary Hypertension, with the objective of informing YUTREPIA’s dosing and tolerability profile in patients with PH-ILD. YUTREPIA was previously referred to as LIQ861 in investigational studies.

About L606 (liposomal treprostinil) Inhalation Suspension
L606 is an investigational, sustained-release formulation of treprostinil administered twice-daily with a next-generation nebulizer. The L606 suspension uses Pharmosa Biopharm’s 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 and potentially mitigating local and systemic side effects. 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) with a planned 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, Inc. (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 population growth 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.
