-- ORLYNVAH^TM Approved by FDA on October 25, 2024—

--Company to Host Conference Call Today at 8:30 a.m. EDT--

DUBLIN and CHICAGO, Nov. 14, 2024 (GLOBE NEWSWIRE) -- Iterum Therapeutics plc (NASDAQ:ITRM), (Iterum), a company focused on delivering next generation oral and IV antibiotics to treat infections caused by multi-drug resistant pathogens in both community and hospital settings, today reported financial results for the third quarter ended September 30, 2024.

"With last month's approval of ORLYNVAH^TM, we have renewed our outreach to potential strategic partners," said Corey Fishman, Iterum's Chief Executive Officer. "As the only oral penem antibiotic approved for commercial sale in the U.S. and the potentially first branded uncomplicated urinary tract infection (uUTI) product to enter this underserved market in over 25 years, the value proposition of ORLYNVAH^TM is significant. There is substantial unmet need in the uUTI market due to antibiotic resistance to existing oral antibiotics which is affecting their efficacy, and reinforces the need for new treatment options like ORLYNVAH^TM."

Highlights and Recent Events

Approval by U.S. Food and Drug Administration (FDA) of ORLYNVAH^TM for uUTI: On October 25, 2024, Iterum received approval from the FDA of its new drug application (NDA) for ORLYNVAH™ for the treatment of uncomplicated urinary tract infections caused by the designated microorganisms Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis in adult women with limited or no alternative oral antibacterial treatment options.
FDA's Orange Book: Iterum has submitted patent information for four U.S. patents for ORLYNVAH^TM that will be listed in FDA's Orange Book: Approved Drug Products with Therapeutic Equivalence Evaluations.
Generating Antibiotic Incentives Now (GAIN) Act Exclusivity: Iterum received confirmation from FDA that an additional five years of marketing exclusivity under the GAIN Act will be added to the exclusivity granted on approval of ORLYNVAH™, giving a total of 10 years of marketing exclusivity.

Third Quarter 2024 Financial Results

Cash, cash equivalents and short-term investments were $14.5 million at September 30, 2024. Based on Iterum's current operating plan, Iterum expects that its current cash, cash equivalents and short-term investments, including proceeds received from the exercise of certain warrants and amounts raised under an ATM offering subsequent to quarter-end through November 4, 2024, will be sufficient to fund its operations into 2025, including through the repayment date of the 6.500% Exchangeable Notes due January 31, 2025 ("Exchangeable Notes").

Research and development (R&D) expenses for the third quarter 2024 were $3.1 million compared to $14.9 million for the same period in 2023. The decrease for the three-month period was primarily due to higher costs incurred in 2023 to support its REASSURE trial, which began enrollment in October 2022 and completed enrollment in October 2023.

General and administrative (G&A) expenses for the third quarter 2024 were $1.8 million compared to $1.8 million for the same period in 2023.

Adjustments to the fair value of derivatives for the third quarter of 2023 were $13.2 million and primarily related to a decrease in the Limited Recourse Royalty-Linked Subordinated Notes (the "Royalty-Linked Notes") as a result of the decrease in management's estimate of the expected cash flows to be received by holders of the Royalty-Linked Notes.

Net loss for the third quarter 2024 was $6.1 million compared to a net loss of $3.9 million for the same period in 2023. Non-GAAP1 net loss for the third quarter 2024 was $4.8 million compared to a non-GAAP¹ net loss of $15.7 million in 2023.

Non-GAAP Financial Measures

To supplement Iterum's financial results presented in accordance with U.S. generally accepted accounting principles ("GAAP"), Iterum presents non-GAAP net loss and non-GAAP net loss per share to exclude from reported GAAP net loss and GAAP net loss per share, share-based compensation expense ($0.1 million and $0.3 million); the interest expense associated with accrued interest on the Exchangeable Notes, payable in cash, shares or a combination of both upon exchange, redemption or at January 31, 2025 ("the Maturity Date"), whichever is earlier ($0.2 million and $0.6 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $1.7 million); and the non-cash adjustments to the fair value of the Royalty-Linked Notes ($0.4 million and $1.2 million) for the three and nine months ended September 30, 2024, and intangible asset amortization ($0.4 million and $1.3 million); share-based compensation expense ($0.1 million and $0.6 million); the interest expense associated with accrued interest on the Exchangeable Notes payable in cash, shares or a combination of both upon exchange, redemption or at the Maturity Date, whichever is earlier ($0.2 million and $0.6 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $1.8 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($13.2 million and $11.4 million) for the three and nine months ended September 30, 2023, respectively.

Iterum believes that the presentation of non-GAAP net loss and non-GAAP net loss per share, when viewed with its results under GAAP and the accompanying reconciliation, provides useful supplementary information to, and facilitates additional analysis by, investors, analysts, and Iterum's management in assessing Iterum's performance and results from period to period. These non-GAAP financial measures closely align with the way management measures and evaluates Iterum's performance. These non-GAAP financial measures should be considered in addition to, and not a substitute for, or superior to, net (loss) / income or other financial measures calculated in accordance with GAAP. Non-GAAP net loss and non-GAAP net loss per share are not based on any standardized methodology prescribed by GAAP and represents GAAP net loss, which is the most directly comparable GAAP measure, adjusted to exclude intangible asset amortization; share-based compensation expense; the interest expense associated with accrued interest on the Exchangeable Notes payable in cash, shares or a combination of both upon exchange, redemption or at the Maturity Date, whichever is earlier; the non-cash amortization of the Exchangeable Notes; and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes for the three and nine months ended September 30, 2024 and September 30, 2023. Because of the non-standardized definitions of non-GAAP financial measures, non-GAAP net loss and non-GAAP net loss per share used by Iterum in this press release and accompanying tables has limits in its usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. A reconciliation of non-GAAP net loss to GAAP net loss and non-GAAP net loss per share to GAAP net loss per share have been provided in the tables included in this press release.
