Analyst · Wedbush Securities. Your line is now open
Good morning, everyone and thank you for joining us. On the call with me today are Tim Albury, Interim Chief Financial Officer; and Dr. Rob Roscigno, Senior Vice President of Product Development and program lead for LIQ861. This morning, I will summarize our recent accomplishments and provide an update on our two pipeline programs, LIQ861 and LIQ865. Tim will provide a summary of our financial results for the first quarter of 2019 and then, I will wrap up with an update on our upcoming key milestones. After our prepared remarks, we will open the call for your questions. We had a productive quarter and continued to execute as planned. I'd like to summarize the accomplishments, since our last earnings call. We completed enrollment of the INSPIRE study, our single pivotal Phase 3 trial evaluating LIQ861 in patients diagnosed with pulmonary arterial hypertension or PAH. We met the primary endpoint of the INSPIRE study by demonstrating safety and tolerability of 861 at the two-month time point. We presented top line data in April from the INSPIRE study at the 39th International Society for Heart and Lung Transplantation meeting, including preliminary data on exploratory endpoints supporting functional and patient outcomes. We initiated Phase 2 enabling toxicology studies for LIQ861, an injectable, non-opioid, sustained release formulation and bupivacaine for the management of local post-operative pain. And we strengthened our capital resources, adding $34.5 million in gross funding. The rapid succession of these accomplishments is an excellent indicator of our team's ability to focus and execute and with those highlights in mind, I'd like to provide some additional details on our two current pipeline programs starting with LIQ861. As a reminder, 861 is an inhaled dry-powder formulation of treprostinil, a prostacyclin analog used to treat PAH by targeting the pulmonary arteries. Like approved nebulized products, 861 combines the demonstrated benefits of prostacyclin therapy, with fewer systemic toxicities than oral or infused options. By applying our print technology, we believe that 861 has the potential to maximize the therapeutic benefits of treprostinil by safely delivering higher doses into the lungs, using a convenient palm-sized disposable inhaler. Having reached the primary endpoint of the INSPIRE trial, I would like to highlight some key takeaways today. First, we believe LIQ861 is safe, well tolerated and has utility as a first line prostacyclin in PAH. As reported in March, of 109 patients enrolled in INSPIRE, 60% were naive to prostacyclin therapy, known as Add-Ons, with the remaining 40% being in the Tyvaso transition group. We did not observe any drug-related serious adverse events in either group and most treatment related adverse events were mild to moderate, consistent with prostacyclin therapy and observed in the first two weeks of treatment. Both patient groups remained on therapy with 93% of patients completing two months of treatment. Second, we believe that LIQ861 may increase the therapeutic window for dosing treprostinil directly to the lung. In one to two breaths, we have delivered 861 at doses that are comparable to nine breaths of Tyvaso, its maximum recommended dose. To date, we have not yet reached the maximum tolerated dose of 861, having administered doses exceeding 150 microgram capsule strength. We are confident that patients can easily administer 861 and avoid some of the systemic toxicities seen with oral and infused prostacyclin analogs. And third, our preliminary data on exploratory endpoints suggests that LIQ861 is being dosed at therapeutic levels as demonstrated by favorable functional and patient reported outcomes. Specifically, at the two-month time point, the functional measure of median six minute walk distance was maintained or improved in both the Add On and Tyvaso transition groups. Additionally, patients in both groups reported physical and emotional improvements in quality of life as measured by the Minnesota living with heart failure questionnaire. Thus with the two-month data from INSPIRE in hand, we remain on-track to submit the NDA in 2019. Along with safety data, we will submit an assessment of the bioavailability and pharmacokinetics of 861 in patients who are transitioned from Tyvaso. As previously disclosed, results from that assessment are on-track to be reported later this quarter. Going forward, we will continue to treat patients in the INSPIRE trial, collecting longitudinal data to support our future commercial activities and to share in scientific disclosures at upcoming congresses and peer review publications. Our next presentation of data will be a poster on May 21st at the upcoming American Thoracic Society conference in Dallas, Texas. Outside of the US, we will conduct an additional clinical trial, exploring the hemodynamic effects of 861 in PAH patients. Though this data is not required or expected to be included for US registration, it will help inform the medical community of 861's impact on right heart function. With this recent clinical data and positive feedback from clinicians, we're increasingly confident that 861 has potential to expand the treatment options for PAH patients. We're laser focused in our plans to submit an NDA in late 2019, as we prepare that submission we will work closely with the FDA, including the FDA's Emerging Technology Program, which provides Liquidia, the opportunity to engage on manufacturing and other detailed plans related to 861, PRINT technology and our novel manufacturing processes. Now, let's move on to LIQ865, our second product candidate, which is an injectable formulation of the non-opioid anesthetic bupivacaine to treat local post-operative pain for three to five days with a single administration. The opportunity for 865 is to increase the options for safe, effective pain relief that can reduce the need for opioids in the early days following surgery. As the next step in our program, we've initiated the toxicology program in March, which will support the first Phase 2 clinical trial. Our goal is to have 865 Phase 2 ready by the end of 2019. In summary, we've made meaningful progress across our clinical programs and are keenly focused on delivering on the next set of milestones. I would now like to turn the call over to Tim, to review our first quarter financial summary.
