Mihael?

Thank you, Kevin. Good afternoon, everyone, and thank you for joining us. This is a very unusual time for all of us, but we at Vanda remain focused on the ways we can innovate to better the lives of the patients we serve. I will first provide an update on diagnose business.We're very happy with the commercial performance for both Fanapt and HETLIOZ in the first quarter. As we reported earlier today HETLIOZ and Fanapt sales grew by more than 20% in the first quarter over the first quarter of 2019. The testament to the value that our products bring and the hard work of our associates.While the method of serving doctors and patients in person has changed due to the COVID-19 pandemic and that resulted in disruption in patient visits and doctor office availabilities.In early March, we instructed our sales force to begin serving the prescribers remotely and adapt to a teleworking model. Our sales force has some great flexibility and adaptability as we have found new ways to still extend our services to both our patients and their prescribers and do so mindful of the safety of all.Stay at home orders and medical office closures are changing the dynamic by which people are seeking and receiving medical services. The disruption in the delivery of medical services may have some impact on new patient starts more than it does on refills of existing prescriptions.On the patient side, with HETLIOZ we experienced better access which may translate to higher adherence. In such it is unclear at this time whether the expected impact in new starts maybe offset by better adherence.Similarly for Fanapt, it is too early to know whether the disruption will have any net negative effect on the number of patients on treatment. This new reality of seeking and…

Thank you, Mihael. I will begin by summarizing our first quarter 2020 financial results. Total revenues for the first quarter of 2020 we're $58 million, a 22% increase compared to $47.7 million for the first quarter of 2019. HETLIOZ net product sales were $35.3 million, a 22% increase compared to $29 million in the first quarter of 2019.The year-over-year growth of the HETLIOZ business was driven by a combination of unit demand and net price favorability. Consistent with trends observed in 2019 the first quarter of 2020, saw a favorable Medicaid payer mix trend as compared to the first quarter of 2019 that resulted in higher net revenue per unit.HETLIOZ net product sales in the first quarter of 2020, decreased by 8% as compared to $38.6 million in the fourth quarter of 2019. HETLIOZ patients on therapy declined in the first quarter of 2020 as compared to the fourth quarter of 2019. Consistent with prior years and expectations in early 2020, we saw a decline in our HETLIOZ patients on therapy attributable to the annual payer disruption linked to new plan years, plan changes and reauthorizations.As expected, this early first quarter decline reversed and patient demand subsequently grew in the remainder of the first quarter consistent with our full-year 2020, plans. As of March 31st, 2020, the specialty pharmacy channel held less than two weeks of inventory as calculated based on trailing demand.Specialty pharmacy’s inventory on hand at the end of the first quarter of 2020 was lower when compared to the fourth quarter of 2019. The value of this inventory change was approximately $100,000.Fanapt net product sales were $22.7 million, a 21% increase compared to $18.8 million in the first quarter of 2019. As of March 31, 2020, wholesalers have increased inventory on hand when compared to the fourth…

Thank you very much, Kevin. At this point, we will be happy to answer any questions you may have.

[Operator Instructions] And we have our first question coming from Mr. Derek Archila from Stifel.

Hey, great. Thanks, guys. This is Ben on for Derek. Thanks for taking my call. Just wondering if you can provide an update on sNDA for SMS? And then can you also remind us what data the FDA was asking for there?

Yes, of course. Just to remind everyone, we filed our sNDA end of last year. And after the initial review, the FDA issued refusal to file. In this refusal to file, they asked a question on the additional information manufacturing. And we have since provided that, and they're asking a question of a bridge study on clinical pharmacology between the public formulation about – in the liquid. The liquid have provided adequate data there and so we're going to be meeting with them in a type of meeting to discuss that and find a way for it.

Okay, thanks. Next one would be I know you had briefly spoke to, but is there any more color you can share about how COVID could impact OpEx going forward, both in respect to R&D and to SG&A as well?

Yes, I would say we do not expect to have a material impact on OpEx, but I would like Kevin to address that.

Yes, obviously, given the challenge how it prevails in conducting our clinical trials, we might see a decrease in some of our existing operating expenses as a result of the pandemic, but we also expect to see some additional operating expenses tied to our COVID-19 responses. And again, we haven't provided guidance from an operating expense perspective, but we have provided you with guidance around our 2020 ending cash, which we previously communicated. We expect to be at greater than $320 million.

Okay, great. Thank you. Last one for us would be, could you just expand a bit more on the rationale for tradipitant as a therapy for COVID-19? Thanks guys.

Yes. Of course, the COVID-19 impacts around the respiratory system and the production of the acute respiratory distress syndrome. The mechanism, of course, it is not clear. However, what is known in our preclinical work is that neurokinin-1 receptor system is involved in modulating the respiratory change in response that you see in several models. In some of these models, as I mentioned are the lack of polysaccharides in this substance, where it has been shown that – like that mice that [indiscernible] mutations in the neurokinin-1 receptor or mice that are wild type 2 with the neurokinin-1 receptor antagonist has been protected from healthy mice induced ARDS. Similar effects that we’re seeing with models of smoke inhalations because of the ideas as well as bias of infection. And based on this rationale the fatality of knowledge around neurogenic information, the hypothesis is that intervention is a neurokinin-1 receptor antagonist nearly dumped the inflammatory response and improved of course of COVID-19 induced pneumonia.

Okay, very helpful. Thanks for taking my questions guys.

Yeah. Thanks.

And our next question comes from the line of Esther [ph] from Oppenheimer.

Hey, guys. Thank you for taking my question. On the study for COVID-19, some of the prior studies related to lung or some of the ongoing studies are using an inhalation method selling within oral dosing. So can you maybe talk about the rationale there and help us understand the pros and cons of an oral dose versus an inhaled dose?

I'm not sure I fully heard your question. Are you asking whether they're providing a oral or a inhaled dose? Is that your question?

My question is that – my question is – I know you're doing an oral dose, so I'm trying to understand getting – I'm trying to understand the pros and cons of using an oral dose to target lung tissue versus an inhaled dose of tradipitant.

Right. Okay. I understood. Well, of course, we have a lot of experience in the oral formulation and administration. And we know from prior animal experiments that the drug distributes well in order it could be lung. So there's no reason to believe that administration to the oral dose will not reach in the lung. Also I have to worry that we don't know how the COVID-19 around infection pursue. It is an inflammatory response that is in general what it is one that is local. Of course, there is lots of damage, but we do not know exactly where the inflammatory response begins.

And in terms of the enrollment for that trial, you’re only running the trial in one location as I understand it. So how is that affecting enrollment? And do you plan to – as in New York, infection rates are declining, do you plan to expand that study to other geographies?

Absolutely. We are now in discussions with a number of sites around the country. And hopefully enrollment will begin in dose as smooth as possible. And you are correct, infections declined in the New York area and hopefully around the country having more sites will allow us to complete the study I think.

Understood. Thank you.

Thanks.

And we do not have any further questions at this time. And I will now hand the call back over to the Vanda management for closing remarks.

Okay. Well, thank you very much all for joining, and we’ll be talking to you soon. Thank you.

Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
