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, 2019 and its subsequent reports on Form 10-Q and Form 8-K. I will now turn the conference over to Phil Gomez, Chief Executive Officer of SIGA. You may begin
Thank you, Dan. I appreciate this opportunity to spend a few minutes updating you on some of SIGA's ongoing development and regulatory activities. Let me start by discussing post exposure prophylaxis or PEP for oral TPOXX. As background, in 2018 oral TPOXX was approved for the therapeutic use in patients with symptomatic smallpox. Due to the prolonged incubation period of human smallpox which is even greater than the challenges being experienced currently with COVID-19, modeling by us and others has indicated that the greatest impact that TPOXX would have on reducing morbidity and mortality would be to use it for post exposure prophylaxis. To that end, we have received a contract from the Department of Defense, Joint Program Executive Office for Chemical, Biological, Radiological, and Nuclear Defense through the medical CBRN defense consortium to support studies necessary for regulatory filing for an expanded PEP indication. We've already had a dialogue with the FDA and believe we have an achievable road map for PEP approval. We are currently planning for a human clinical study to test how co-administration of TPOXX together with smallpox vaccine might affect acquisition of a protective immune response. The PEP work represents an exciting opportunity. In addition to PEP, there's other work ongoing in connection with oral TPOXX. As background, with the FDA's approval in 2018, we were tasked with four post-marketing commitments which are supported by our contract with BARDA. On this score, we're making excellent progress toward accomplishing these tasks. First, we've established a field study protocol for collecting and analyzing data in the event TPOXX is deployed and used as smallpox patients. Second, we and our colleagues at the Centers for Disease Control, have completed genome sequencing and drug sensitivity testing on additional previously untested strains of ribovirus containing variants of the TPOXX target protein. All the variants were found to be sensitive to the drug. The final report has been submitted to the FDA for their review. Third, we've conducted and completed in-vitro analysis for potential drug-drug interactions. We're now poised to expand this analysis into a clinical study and have concurrence from the FDA on a proposed medical protocol. This trial of course is on hold until the current COVID-19 pandemic is on the wane and clinical trials can safely resume. Fourth, after demonstrating that mixing TPOXX capsule ingredients with food or drink was not adequate for dosing patients under 13 kilograms, the FDA has agreed that an alternate pediatric formulation is needed. With that in mind, we're in the early stages of developing a powder for reconstitution for this use. We believe this program has been fully funded through the NDA by BARDA through an option exercised earlier this year. Beyond clinical work, we're also very busy on the regulatory front. First, we're preparing a marketing authorization application, MAA, submission for the European Medicines Agency, the EMA. We have a pre-submission meeting coming up shortly. And barring any unforeseen circumstances, we anticipate submitting the completed application for review under the exceptional circumstances pathway in the second half of 2020. Second, we're preparing an extraordinary use of new drug, EU&D application for submission to Health Canada. We have executed our pre-submission meeting and are on track to submit the completed application as early as Q4 2020. Of note, both the EMA, MAA and the Health Canada, EU&D are seeking a broader indication for use against all the human orthopoxvirus pathogens, vaccinia, cowpox, monkeypox and variola. If granted, this will allow TPOXX to treat patients infected with these agents, in particular, cowpox and monkeypox which have periodic endemic outbreaks in Europe and Africa, respectively. Third and finally, we are pushing towards the finish line with the NDA submission for the IV formulation of TPOXX. We have already received our pre-NDA CMC and pre-NDA file medical meeting feedback. We plan on filing the IV NDA in late 2020. I'd like to note that the COVID pandemic has impacted the way we work with regulatory agencies. We've had several face-to-face meetings moved to teleconferences or written correspondences. But to date we have not seen any impact on time line or receiving the substantive feedback that we need to continue to progress our development programs. So in summary, the R&D group at SIGA are working hard towards expanding the utility of TPOXX for new indications and formulations and to gain approval in additional jurisdictions to allow for its eventual acquisition and use in biodefense and against emerging orthopoxvirus infectious diseases. Thanks for your attention. Back to you, Phil.
