Liquidia Announces Collaboration to Develop a New Infusion Pump for Subcutaneous Delivery of Treprostinil Injection to Treat Pulmonary Arterial Hypertension (PAH)

  • Liquidia and Sandoz will collaborate with Mainbridge Health Partners to develop a new infusion pump
  • Liquidia and Sandoz have also extended the term of their promotion agreement for Treprostinil Injection until 2032

MORRISVILLE, N.C., Dec. 05, 2022 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA) (Liquidia or the Company) announced today a collaboration with Sandoz Inc. (Sandoz) and Mainbridge Health Partners LLC (Mainbridge) to support the development of a new subcutaneous pump for infusion of Treprostinil Injection, a generic form of Remodulin®, for which Liquidia has the exclusive rights to promote and commercialize with Sandoz.

Scott Moomaw, Senior Vice President of Commercial at Liquidia, stated: “Liquidia remains committed to addressing unmet needs in the administration of treprostinil, whether it be inhaled or infused. In order to alleviate the single-source dependence on the existing CADD-MS 3 system, Sandoz and Liquidia have found a great partner in Mainbridge with the skills and know-how to efficiently develop a new infusion pump using technology that has been previously approved by the U.S. Food and Drug Administration (FDA) for delivery of insulin. Our goal is to ensure the widespread availability of our trusted and proven Treprostinil Injection to the benefit of physicians, payors and patients in the PAH community.”

To enable the collaboration, Sandoz and Liquidia will enter into a joint agreement with Mainbridge (Pump Agreement). Mainbridge will perform all development, validation and testing activities required for the pump and related consumables. The parties anticipate submitting a 510(k) in 2023 for FDA clearance. Sandoz and Liquidia will split equally the development costs. In connection with the execution of the Pump Agreement, Liquidia and Sandoz also agreed to extend their promotion agreement for Treprostinil Injection by another five years until December 31, 2032.

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, who holds the Abbreviated New Drug Application (ANDA) with the FDA.

About YUTREPIA™ (treprostinil) inhalation powder
YUTREPIA is an investigational, inhaled dry powder formulation of treprostinil delivered through a proven, convenient, palm-sized device. On November 5, 2021, the FDA issued a tentative approval for YUTREPIA, which is indicated for the treatment of pulmonary arterial hypertension (PAH) to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. 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 optimal 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 was previously referred to as LIQ861 in investigational studies.
