Thanks Jason and good afternoon and thank you to everyone for joining us. On the call with me today are Rich Katz, our Chief Financial Officer and Dr. Rob Roscigno, Senior Vice President of Product Development and Program Lead for LIQ861. I will summarize our progress and recent accomplishments in 2020. Rich will provide a brief summary of financial results for the first quarter. And then I will conclude our prepared remarks and open the call for your questions. Like most of the world, we have endured a new way of living and working during the eight weeks since our last call. I'm happy to report that despite some logistical challenges that the world's been facing in a workforce deployed at home, our team has continued to successfully deliver on its objectives for 2020. First and foremost, we submitted and the FDA has accepted our NDA for LIQ861. As a reminder, 861 is an inhaled dry powder formulation of treprostinil, a prostacyclin analog used to treat pulmonary arterial hypertension, or PAH, by targeting the pulmonary arteries. We believe that 861 has the potential to maximize the therapeutic benefits of treprostinil by safely delivering higher doses directly into the lungs using a convenient, palm-sized dry powder inhaler. In April, the FDA confirmed a PDUFA goal date of November 24, 2020. We feel well prepared to support the agency's review during this period. We feel fortunate to have completed all of the work required to submit the NDA prior to any impact from the COVID pandemic. All U.S. patients enrolled in an open-label extension study, continued to receive treatment and European patients enrolled in a hemodynamic dose response study are being monitored. However, in light of the pandemic in an interest of patient safety, we have paused enrollment in the European trial until the pandemic has subsided. As a reminder, this study is being conducted to increase the medical information available on the impact of 861 and is not required for NDA approval by the FDA. So we expect to complete it once it's safe to do so. We have also shared the final clinical data included in the NDA with the medical community. In January, we presented the comparable bioavailability data that establishes the pharmacokinetic bridge between 861 and Tyvaso, the reference listed drug. Last month, we presented the final safety and tolerability data from our INSPIRE trial of 861 at the Month 2 time point. Further confirming that 861 had met the primary endpoint and potentially offers a convenient, safe, well-tolerated option for inhaled prostacyclin therapy. Overall, the study results demonstrated that the treatment emergent adverse events or TEAEs or similar to inhaled prostacyclin and mostly mild-to-moderate in nature. We believe that these two studies inspire in the PK bridging study addressed the FDA's guidance for potential approval under the 505(b)(2) pathway. We will continue to share data from the INSPIRE study at key medical conferences throughout the year with the next release focusing on the exploratory end points from INSPIRE. We have every reason to be excited about our results from INSPIRE and the response from physicians and patients alike regarding the potential opportunity for LIQ861. As you know, treprostinil has been a key component of PAH treatment for nearly 20 years. We have a strong baseline for 861, the challenge for patients with currently approved inhaled therapy is that when needed, they require their nebulizer availability of distilled water and some type of power source to administer their treatment always, whether at work, at home or at play. It is always a present concern among patients. Our PRINT technology allowed us to take this trusted molecule and engineer it into highly uniform particles with specific aerodynamic properties including shape, size and weight. To enhance deep-lung delivery with unprecedented convenience in the form of a palm-sized dry powder inhaler, that can be utilized virtually anywhere. Because of its ability to address unmet needs in the treatment of PAH, there is significant interest amongst physicians and patients to use 861 immediately. A recent quantitative survey conducted by Liquidia conveyed that nearly 50% of treating physicians say that they intend to prescribe 861 in place of current prostacyclin therapies as soon as it is available. And to that point, we attend to make it available as soon as possible. As required by our 505(b)(2) NDA, we made a paragraph IV certification against the patents listed in the orange book for the reference listed drug. We believe these patents are invalid unenforceable or will not be infringed by the commercial manufacturer use or sale of 861. As you likely know, the active ingredient treprostinil is a readily available generic molecule and our PRINT dry powder particles and delivery device are highly differentiated from the nebulizer-based reference listed drug. Acknowledging that our competitor may take action under the Hatch-Waxman Act to delay the innovation of 861 from reaching patients, we have taken proactive steps to bring 861 to patients without undue delay. To this end, we petitioned the U.S. patent and trademark office or USPTO for inter partes review or IPR of two of the patents listed in the Orange Book and directed toward processes or producing the generic treprostinil molecule. These two patents are continuations of an earlier patent that was found invalid by the USPTO in a 2016 IPR, and we believe these patents are invalid for substantially the same reasons. The details of our IPR petitions can be found online at the patent trial and appeal PTAB section of the USPTO. While we cannot comment on the timeframe for FDA's review of the NDA or our competitors’ potential actions, we can’t confirm that we remain committed to taking all actions available to introduce 861 to PAH patients as soon as possible. And lastly, while much of 2020 has focused on the advancement of 861 to potential FDA approvals of our NDA, we have continued to invest in our proprietary pipeline, non-clinical studies of LIQ865, our formulation of bupivacaine to treat local postoperative pain for three to five days remain on track to inform and support future Phase 2 studies, while formulation activity in support of new inhaled products is increasing. We look forward to updating you on these programs in the future as data becomes available. I would now like to turn the call over to Rich to review our first quarter financial summary.
