Liquidia Technologies Presents Phase 3 Trial Data for LIQ861 at the ISHLT 39th Annual Meeting & Scientific Sessions
“The two-month results of the INSPIRE trial are promising for patients with PAH. Inhaled therapy offers the benefit of getting drug directly to the lungs and we are encouraged that the safety, tolerability and quality of life metrics suggest that LIQ861 is an attractive and more convenient therapy versus the currently available inhaled therapies,” said Dr. Hill.
“We are continuing to demonstrate the potential benefits of LIQ861 as we present additional data from the INSPIRE trial,” said
The INSPIRE trial includes two groups of PAH patients, comprised of 65 prostacyclin-naïve patients that were stable on ≤2 approved oral PAH therapies (add-on) and 44 patients transitioning from Tyvaso® (transition). Most TEAEs occurred in the add-on population and were observed mainly during initial exposure to LIQ861 at the 25mcg dose. Overall, TEAEs observed were consistent with inhaled prostacyclins and considered mild to moderate, including cough, headache and throat irritation. No serious adverse events (SAEs) related to LIQ861 were observed during the two month period.
Duration of Treatment and Patient Quality of Life
Most patients, 101 of 109 (92.7%), remained on LIQ861 at two months duration of treatment, with 59 of 65 (90.8%) add-on patients and 42 of 44 (95.5%) transition patients. Patients continue to receive treatment beyond month 2 with initial dosing in
Exploratory endpoints of the INSPIRE trial demonstrated favorable functional and patient outcomes, as indicated by the Minnesota Living with Heart Failure Questionnaire (MLWHFQ) and measurement of six-minute walk distance (6MWD). MLHFQ is a patient-oriented measure of the adverse effects of heart failure on a patient’s physical and emotional aspects of life. A five-point change is the minimal difference considered to be clinically important. The median MLWHFQ score at month 2 for all patients improved from 34 to 24, with significant changes observed in both the add-on and transition patient groups, from 37 to 29 and 30 to 19, respectively. Median 6MWD at baseline and 2 months was 395m and 408m in the add-on group and 428m and 449m in the transition group.
LIQ861 is an inhaled dry powder formulation of treprostinil designed using Liquidia’s PRINT technology to enhance deep-lung delivery using a convenient, palm-sized, disposable dry powder inhaler (“DPI”) for the treatment of PAH. Liquidia believes LIQ861 can overcome the limitations of current inhaled therapies and has the potential to maximize the therapeutic benefits of treprostinil in treating PAH by safely delivering higher doses into the lungs.
About INSPIRE Clinical Trial
Liquidia’s pivotal open-label Phase 3 clinical trial, known as INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil, is designed to evaluate patients who have either been under stable treatment with nebulizer-delivered treprostinil for at least three months and are transitioned to LIQ861 under the protocol or patients who have been on stable treatment with no more than two non-prostacyclin oral PAH therapies for at least three months and have their treatment regimen supplemented with LIQ861 under the protocol. The primary objective of the INSPIRE study is to evaluate the long-term safety and tolerability of LIQ861. For more information, please visit https://clinicaltrials.gov/ct2/show/NCT03399604.
About Liquidia Technologies
Liquidia Technologies is a late-stage clinical biopharmaceutical company focused on the development and commercialization of human therapeutics using its proprietary PRINT® technology to transform the lives of patients. Currently, Liquidia is focused on the development of two product candidates using its PRINT® particle engineering platform: LIQ861 for the treatment of PAH and LIQ865 for the treatment of local post-operative pain. Being evaluated in a Phase 3 clinical trial (INSPIRE), LIQ861 is designed to improve the therapeutic profile of treprostinil by enhancing deep-lung delivery and achieving higher dose levels than current inhaled therapies by using a convenient, palm-sized, disposable DPI. LIQ865, for which Liquidia has completed two Phase 1 clinical trials, is designed to deliver sustained-release particles of bupivacaine, a non-opioid anesthetic, to treat local post-operative pain for three to five days through a single administration.
