Operator: Good afternoon, ladies and gentlemen. Welcome to the Atea Pharmaceuticals’ First Quarter 2023 Financial Results and Business Update Conference Call. At this time, all participants are in a listen-only mode. Following the formal remarks, we will open the call up for your questions. I would now like to turn the call over to Jonae Barnes, Senior Vice President of Investor Relations and Corporate Communications at Atea Pharmaceuticals. Ms. Barnes, please proceed.
Jonae Barnes: Thank you, operator. Good afternoon, everyone, and welcome to Atea Pharmaceuticals’ first quarter 2023 financial results and business update conference call. Earlier today, we issued a press release, which outlines the topics we plan to discuss. You can access the press release as well as the slides that we will be reviewing today by going to the Investors section of our website at ir.ataepharma.com. With me today from Atea are Chief Executive Officer and Founder; Dr. Jean-Pierre Sommadossi; Chief Development Officer; Dr. Janet Hammond; Chief Medical Officer, Dr. Arantxa Horga, Financial Officer and Executive Vice President of Legal, Andrea Corcoran; and our Chief Commercial Officer, John Vavricka. They will all be available for the Q&A portion of today’s call.
Before we begin the call and as outlined on Slide 2, I would like to remind you that today’s discussion will contain Forward-Looking Statements that involve risks and uncertainties. These risks and uncertainties are outlined in today’s press release and in the Company’s recent filings with the Securities and Exchange Commission, which we encourage you to read. Our actual results may differ materially from what is discussed on today’s call. With that, I will now turn the call over to Jean-Pierre.
Jean-Pierre Sommadossi: Thank you, Jonae. Good afternoon, everyone and thank you for joining us. As you will see on Slide 3, we have had a busy start of the year with progress across our COVID-19 and HCV program. I will begin with a few highlights from our COVID-19 program. First, we remain laser focused on the execution on our global SUNRISE-3 study, where I’m pleased to report that as of today, we have a broad geographic footprint with regulatory approvals in over 50% of the targeted countries. Just last month, we were excited to receive from the U.S. FDA, a fast track designation for Bemnifosbuvir for treatment of COVID-19, which has the potential to expedite the development of Bemnifosbuvir. We presented multiple data sets of scientific meetings, including CROI, ICAR and ECCMID, each of which highlighted Bemnifosbuvir clinical efficacy and favorable safety profile, including a compelling drug interaction profile.
Finally, we continue to make progress advancing our second generation protease inhibitor. Turning to HCV, we remain on target for the first patient 2b dose in our phase 2 combination trial this quarter. And we continue to expect initial results from our first cohort of 60 patients by year-end. Data recently presented the ICAR support our combination profile, and new in vitro results indicate a highly compelling antiviral profile compared to the current standard-of-care. Moving to Slide 4, as I mentioned, we had a large presence at the major Antiviral medical meetings during the first quarter. Some of the key highlights of our current program include the full results in the MORNINGSKY trial, presented showing a 71% reduction in risk of hospitalization, with benefits review as compared to the placebo in the MORNINGSKY trial was a subset showing 82% reduction in risk in patient over 40-years old.
Low risk of drug-drug interactions with commonly prescribed medicine for COVID-19 and HCV, which we believe is a key feature of the drug. Slide 5 outlines the data presented and medical meetings beyond our COVID-19 program. At ICAR were presented HCV combination data showing the Bemnifosbuvir portal individual synergistic antiviral activity and in vivo preclinical safety without adverse indirect interactions. In addition, we presented data AGNC 2023 on the AT-752 for dengue. While as you know, with deprioritize our dengue program and the development of AT-752 in February 2023, we are exploring opportunistic ways to continue to move this program forward. Moving now to Slide 6. AT-511 the three bay’s of Bemnifosbuvir has been shown to be a potent inhibitor of SARS-CoV-2 in vitro, new results demonstrated that AT-511 also, I suppose, an antiviral activity against the source code to micron civilian XBB.
This is consistent with the privacy demonstrated in vitro potent antiviral activity against other variants of concern and of interest including alpha, beta, gamma, epsilon delta, and various all Omicron sub variant BA1, BA2, BA4 and BA5 and now the XBB. I will now turn the call over to Janet.

Janet Hammond: Thank you. Turning to Slide 8, the COVID market dynamics continue to shift and the U.S. COVID-19 Public Health Emergency is set to expire this week. Last Friday, the World Health Organization declared the end to the global health emergency. They also went on to say that COVID as a virus is here to stay, which is highlighted by the fact that globally nearly 2.8 million new cases and over 17,000 deaths were reported in the last 28-days. One fact remains, there is still a large unmet medical need for the treatment of COVID-19. We are experiencing waning immunity with both vaccines and natural infection exacerbated by the lower booster uptake, with only approximately 17% of the U.S. population having received a booster and in some patient populations, there is also a failure to mount any immune response to vaccines.
Moreover, the limitations of currently available oral antiviral are considerable due to safety concerns and drug-drug interactions with commonly prescribed medications, such as seizure medications, antipsychotics, anticoagulants and more. This significantly limits the use of these drugs in high risk elderly and immunocompromised patients who are the most vulnerable and most likely to have the most severe cases of COVID. As a result of this remaining unmet medical need and emergency use authorization is still available assessment criteria for assurance on that. Turning to Slide 9, as Jean-Pierre mentioned earlier, we are seeing strong operational execution from our clinical team. The global SUNRISE-3 geographical footprint now has regulatory approvals in over 50% of the targeted countries and patient enrollment continues.
COVID-19 continues to evolve with new variants and waves such as what we are experiencing with the Omicron sub variant XBB 1.16, the there we are showing again good in vitro pregnancy with Bemnifosbuvir. Our goal is to enroll patients from circulating waves by being well positioned with our extensive global footprint as new variants and waves of infection merge. SUNRISE-3 is focusing on high risk patients that are at the greatest risk for disease progression to severe COVID-19 maybe into hospitalization or mortality. Its primary endpoint is all caused hospitalization all day through day 29 in at least 1400 patients from the monotherapy cohort. I will now turn the call back to Jean-Pierre to review our HCV program.
Jean-Pierre Sommadossi: Thank you, Janet. Moving now to our Hepatitis C program of a fixed dose combination of benefits Bemnifosbuvir and Ruzasvir. We believe that our combination has the potential to improve upon the current standard-of-care by offering a put it in a bit of three shorter duration options for HCV patients with and without cirrhosis. Being the positive is a highly potent and genotypic with demonstrated clinical antiviral activity. In addition Ruzasvir is potent NS5 inhibitor as shown grown genotypic in vitro antiviral activity with EC50 lower that 10 against all genotypes with demonstrated clinical antiviral activity. Naturally occurring NS5A resistant variants have emerged and can impact the effectiveness of currently available HCV treatments.
We recently profiled the antiviral activity of both Bemnifosbuvir and Ruzasvir against a panel of previous NS5A resistance associated variants selected in vitro or identifying HCV patients who have failed treatment who is the current standard-of-care. We are pleased to share this data with you now, supporting that we have the potential for best-in-class regiment. As outlined on Slide 11, recent data show the Bemnifosbuvir retain high potency in vitro being at least 10 times more potent than sofosbuvir against all HCV genotype 1A and genotype 3A, NS5A resistance associated variance or we call it rise. In addition, as you will see on Slide 12 Ruzasvir is also a potent NS5A inhibitor. In the rapid NS5A Ruzasvir has demonstrated a move forth favorable in vitro efficacy profile as compared to the Ruzasvir and similar antiviral activity to velpatasvir, which is the most potent NS5A inhibitor currently approved.
In fact, and as outlined on Slide 13, in the same replica effect Ruzasvir was shown to be five to 10 fold more potent number velpatasvir against RAF HCV genotype 1A, and a difficult to treat genotype 3A. Turning to Slide 14. In summary, the combination of Bemnifosbuvir and the Ruzasvir is very important, and has the potential to be the best-in-class regiment based on its pain, genotypic antibiotic, antiviral potency, low risk for drug-drug interaction, absence of food effects, and potential for short treatment duration. Indeed, we are targeting eight weeks of therapy with the potential for even a shorter duration. This profile, along with the totality of the preclinical data, give us greater confidence in the potential of this combination to become the new standard-of-care.
As you will see, on Slide 15 normally diagnosed HCV cases in the U.S. increased 400% between 2010 and 2020. And as just mentioned, this is an area where we believe that Bemnifosbuvir and Ruzasvir combination can be especially effective, given its potential for short treatment duration with a highly compelling profile. According to WHO 58 million people globally have chronic HCV infection and approximately 1.5 million new infections occurring every year. We lose nearly 300,000 people to HCV related liver disease each year. And this has become such a problem even in the U.S. when the U.S. government has recently proposed an HCV program with the goal to eliminate HCV. This is important because it recognize this resurgence and acknowledges the need for new effective treatment options.
On Slide 16, we outline our phase 2 open label study of Bemnifosbuvir and Ruzasvir in HCV patients. This study will enroll approximately 280 HCV infected direct acting antiviral naive patients across all genotypes, including a leading cause of approximately 60 patients. Patients who will be administered 550 milligrams any positive in combination with 180 milligram versus via was daily for eight weeks. The primary endpoint of the study of safety affecting and sustained virologic response or SVR at week 12 post treatment. Although virologic endpoints include virologic failure, as we are with 24, post treatment and resistance. Regulatory submissions for the initiation of this global trial ongoing and dosing of patient in this clinical trial is expected to begin this quarter.
In initial data for the leading cohort of approximately 60 patients is anticipated around the end of the year. With that, I will now turn the call over to our CFO, Andrea Corcoran to our financial updates.
Andrea Corcoran: Thank you Jean-Pierre. As Jonae mentioned in her introductory remarks earlier today, we issued a press release containing our financial results for the first quarter of 2023. The statement of operations and balance sheet can be found on Slide 18 and 19. First quarter of 2023 each of R&D and G&A expenses remained relatively consistent with the first quarter of 2022. As we further our clinical development of both our COVID-19 and HCV clinical programs in 2023. We do anticipate that R&D expenses will increase in a measured way as these programs advance. We are exercising focused financial discipline to manage spend as we invest in these programs. At the end of the first quarter of 2023, our cash, cash equivalents and marketable security balance was $620.5 million. Based on our current plans, we are reiterating our cash guidance with a run rate into 2026. I will now turn the call back over to Jean-Pierre for closing remarks.
Jean-Pierre Sommadossi: Thank you, Andrea. In conclusion, we have already made notable clinical and operational progress across our COVID-19 and HCV program so far this year. We also presented significant, scientific and clinical evidence in support of the potential of our clinical programs among an audience of leading virologist and infectious disease specialists at several scientific conferences. We believe this data continue to validate our approach and will enhance our development efforts as we advance our global clinical trials. We look forward to reporting our continued progress throughout the year. As always, we thank you for your continued interest and support of Atea as together we strive to address the unmet medical needs of patients with serious viral infections. With that operator, we will now open the call up to your questions.
