The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug substance (“IV BDS Options”), and there are corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV FDP Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 19C BARDA Contract includes: three separate IV BDS Options, each providing for the bulk drug substance equivalent of 32,000 courses (as currently defined within the contract) of IV TPOXX®; and three separate IV FDP Options, each providing for 32,000 courses of final drug product of IV TPOXX®. BARDA has the sole discretion as to whether to simultaneously exercise IV BDS Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV FDP Option). To date, BARDA has exercised two of the three IV BDS options and two of the three IV FDP options. If BARDA decides only to exercise the remaining IV BDS Option, then the Company would receive payments up to $10.2 million; alternatively, if BARDA decides to exercise the remaining IV BDS Option and IV FDP Option, then the Company would receive payments up to $25.6 million. BARDA may also decide not to exercise either remaining option. For each set of options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 32,000 courses), BARDA has the option to independently purchase IV BDS or IV FDP. The Company estimates that sales of the IV formulation under this contract (under current terms), assuming the remaining IV FDP Option was exercised, would have a gross margin (sales less cost of sales, as a percentage of sales) that is less than 40%.

In connection with the 2022 global response to an mpox outbreak, a series of observational and randomized, placebo-controlled clinical trials were initiated to assess the safety and efficacy of TPOXX® in participants with mpox. These randomized clinical trials are seeking to collect data on the potential benefits of using TPOXX® as an antiviral treatment for active mpox disease. As of September 30, 2024, there were four active randomized, placebo-controlled clinical trials enrolling patients, subject to patient availability, at sites located in, among other places, the United States and South America. Additionally, a randomized, placebo-controlled clinical trial in the Democratic Republic of the Congo ("DRC") known as PALM 007 (Tecovirimat for Treatment of Monkeypox Virus - NCT05559099), which is funded and sponsored by the National Institutes of Health's (NIH) National Institute of Allergy and Infectious Diseases (NIAID), recently completed enrollment and reported preliminary topline results. Although the study did not meet its primary endpoint of a statistically significant improvement in time to lesion resolution within 28 days post-randomization for patients in the DRC with monkeypox (mpox), who were administered TPOXX® compared to patients who were administered placebo, improvement versus placebo was observed in patients receiving TPOXX® whose symptoms began seven days or fewer before randomization and patients with severe or grave disease, defined by the World Health Organization (WHO) as having 100 or more skin lesions.

Current wording

In connection with the 2022 response to a global mpox outbreak, a series of observational and randomized, placebo-controlled clinical trials were initiated to assess the safety and efficacy of TPOXX® in participants with mpox. The purpose of these randomized clinical trials is to seek to collect data on the potential benefits of using TPOXX® as an antiviral treatment for active mpox disease. As of March 31, 2025, two of the randomized, placebo-controlled clinical trials reported preliminary topline results: a randomized, placebo-controlled clinical trial in the Democratic Republic of the Congo ("DRC") known as PALM 007 (Tecovirimat for Treatment of Monkeypox Virus - NCT05559099), which is funded and sponsored by the National Institutes of Health's (NIH) National Institute of Allergy and Infectious Diseases (NIAID); and the Study of Tecovirimat for Human Mpox Virus (STOMP) clinical trial (NCT05534984), which is a randomized, placebo-controlled, double-blind study sponsored and funded by NIAID to evaluate the safety and efficacy of tecovirimat for the treatment of people with laboratory-confirmed or presumptive mpox disease that included enrollees from Argentina, Brazil, Japan, Mexico, Peru, Thailand, and the United States. The PALM 007 study did not meet its primary endpoint of a statistically significant improvement in time to lesion resolution within 28 days post-randomization for patients in the DRC with mpox who received TPOXX® compared to patients who received placebo. Some improvement versus placebo was observed in patients receiving TPOXX® whose symptoms began seven days or fewer before randomization and patients with severe or grave disease, defined by the World Health Organization (WHO) as having 100 or more skin lesions, however the significance of these data have not been established. An interim analysis of data from the STOMP study showed that TPOXX® did not demonstrate efficacy in time to skin and mucosal lesion resolution compared to placebo in patients with mild to moderate clade II mpox. Based on this result and additional analyses, the study Data Safety and Monitoring Board (DSMB) recommended to stop enrolling patients in the randomized arms of the study. NIAID accepted this recommendation and subsequently decided to take a similar action in the open label arm of this study, which included severe and at-risk of developing severe disease patients. Data analysis is not yet complete for primary endpoint subgroups and detailed secondary and exploratory endpoints. In both studies, TPOXX® exhibited a safety profile comparable to placebo. These safety results are consistent with prior studies and further support the strong safety profile that has been observed with tecovirimat over the past 15 years.

Previous wording

The decrease of approximately $1.2 million primarily reflects the decrease in international promotion fees due to the decrease in international sales in 2024 in comparison to the same period in 2023, partially offset by higher compensation expense associated with the hiring of multiple executive officers this year.

Current wording

Selling, general and administrative (“SG&A”) expenses for the three months ended March 31, 2025 and 2024 were $5.7 million and $7.9 million, respectively. The decrease of approximately $2.2 million primarily reflects the decrease in international promotion fees due to the decrease in international sales in 2025 in comparison to the same period in 2024, as well as lower compensation expense associated with the nonrecurrence in 2025 of certain one-time payments and equity grants that occurred in 2024 in connection with new hires.

Previous wording

Research and development (“R&D”) expenses for the three months ended September 30, 2024 and 2023 were $3.0 million and $3.6 million, respectively, reflecting a decrease of approximately $0.6 million. The decrease is primarily attributable to lower direct vendor-related expenses incurred in connection with a decrease in activities under the PEP Label Expansion R&D Contract, partially offset by an increase in compensation expense in connection with an increase in headcount.

Current wording

Research and development (“R&D”) expenses for the three months ended March 31, 2025 and 2024 were $3.5 million and $3.1 million, respectively, reflecting an increase of approximately $0.4 million. The increase is primarily attributable to the implementation of information technology enhancements, higher compensation expense in connection with an increase in headcount, and an increase in the usage of regulatory consultants.

We prepare our condensed consolidated statement of cash flows using the indirect method.

These reconciling items include but are not limited to stock-based compensation, deferred income taxes, and changes in the condensed consolidated balance sheet for working capital from the beginning to the end of the period.
