Analyst · factors that could cause results to differ, please see the company's filings with the Securities and Exchange Commission, including without limitation, the company's annual report on Form 10-K for the year ended December 31, 2020, and its subsequent reports on Form 10-Q and Form 8-K. I would now like to turn the call over to your host Dr. Phil Gomez, CEO of SIGA Technologies. Please go ahead sir
Thank you, Phil. I'm pleased to have the opportunity to update our investors on the progress being made by the SIGA research and development team. As Phil mentioned, for Oral TPOXX, we continue to advance our efforts to achieve regulatory approvals outside the US. Both the EMA MAA and the Canadian NDS applications, which were submitted last year have been validated by the respective agencies and are now undergoing full review. We are responding to any comments or questions that arise in a timely manner in order to expedite the review process as much as possible and we hope to achieve those regulatory approvals in a late 2021 or early 2022. As a reminder, both the MAA and NDS applications are requesting an indication for TPOXX for use against orthopoxviruses, which is a broader indication than the current FDA-approved label. This is important as conversations with a broad range of countries as well as NGOs indicate that many government officials are thinking broadly about the best way to pursue health security and a therapy for a broad range of orthopoxviruses such as smallpox, Vaccinia, cowpox and monkeypox could resonate with this type of preparedness strategy. We have seen monkeypox cases continue to be an issue in Central Africa, and cases outside of Africa in the U.K., Singapore, and Israel. It's important to note that, we continue to get requests from around the globe to use TPOXX to treat individuals infected with Vaccinia virus, cowpox, and monkeypox on a compassionate use basis. We review those requests on a case-by-case basis. Separately, we are working on a collaboration that would allow us to reach a broader number of individuals who developed monkeypox in Central Africa and expect to announce that effort later this year. On the FDA regulatory front, we continue to progress our efforts to achieve regulatory approval of Oral TPOXX for post exposure prophylaxis. As we have discussed previously, the strategy for this program has evolved as we have talked with the FDA to get feedback on our plans. And I'm pleased to say, we believe we have an agreement on the path to ultimate approval. Together with our colleagues at the U.S. Department of Defense, final protocols for the remaining two clinical studies have been developed and shared, and obtained consensus with the FDA. Having now received agreement from the FDA with respect to our protocols, we are working towards potentially launching both studies, concurrently as soon as the third quarter of this year, depending on a series of factors, including the general status of clinical trial availability in light of the COVID-19 pandemic. As a quick reminder, the two human studies we are planning for PEP are. One, a study to evaluate whether there is any interference with the, Jynneos vaccine, and two, an expanded safety study. We anticipate these studies will be completed in 2022, with data to support the PEP indication. We are confident based on the mechanism of action of TPOXX it will not interfere with the Jynneos vaccine. Moreover, the outcome of these studies are not required for the purchase TPOXX doses for PEP, as we already have an FDA-approved product, and stockpiling may occur in advance of the label expansion if the government determines there's a need for it. With regard to IV TPOXX, the NDA is nearing completion. And will be submitted to the FDA as soon as April. If all goes well, the U.S. FDA submission for IV TPOXX, should receive an approval in the early 2022 time frame. In addition to the PEP and IV programs for TPOXX, we also continue to progress our pediatric formulation, which is a powder for reconstitution. Prototype formulations have been developed and tested for dissolution and solubility versus the Oral TPOXX capsules. We are selecting the formulation with the best properties and are preparing to initiate human clinical trials shortly, to evaluate and optimize pharmacokinetic performance. We have shared our development plans for these products with the FDA. And they had no comments. Lastly, we continue to explore new avenues for the use of TPOXX, outside of orthopox diseases. We have collaborations with several companies in oncology that utilize Vaccinia virus in the product strategy. Given the challenges of advancing products in this field, to late-stage development, this may still take time. We continue to be interested in the long-term potential of TPOXX to support these therapies, but recognize that most of the current investigational products are in early clinical testing. And it will take time to determine, what if any market potential there is, for TPOXX in this regard. On TPOXX our efforts to develop a second small box antiviral ST-357 continue. In collaboration with the National Institute of Health, we're conducting a medicinal chemistry campaign to improve the chemical attributes of the molecule to produce a lead candidate for advancement into development. We continue to seek additional outside funding to accelerate this effort. Finally, let me close by thanking the SIGA staff, for their tireless efforts and tremendous contributions. In these difficult and unprecedented times, they pivoted to working remotely and have continued to perform efficiently, effectively and cooperatively to advance the projects on-time, on-schedule, and simultaneously execute on our federal contracts and commitments. A special thanks to the, SIGA IT team, for providing us with the tools to be successful. I'll now pass the call over to Dan, who will discuss our fourth quarter and full year financials. Dan?
