—Cash Runway into Q3 2024–

DUBLIN, Ireland and CHICAGO, Aug. 11, 2023 (GLOBE NEWSWIRE) — Iterum Therapeutics plc (Nasdaq: ITRM) (Iterum), a clinical-stage pharmaceutical company focused on developing 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 second quarter ended June 30, 2023.

“We recently achieved 50% patient enrollment and expect to complete the planned enrollment of 1,966 patients in our REASSURE trial in the first quarter of next year. We have over 140 clinical trial sites currently open to enrollment in the U.S.,” said Corey Fishman, Iterum’s Chief Executive Officer. “Top-line data is expected in the second quarter of 2024, with a potential resubmission of our new drug application (NDA) to the U.S. Food and Drug Administration (FDA) in the second half of 2024.”

Highlights and Recent Events

• Enrollment in REASSURE Clinical Trial Ongoing: Iterum began enrollment in its pivotal Phase 3 clinical trial, REASSURE (REnewed ASsessment of Sulopenem in uUTI caused by Resistant Enterobacterales), for the treatment of uncomplicated urinary tract infections (uUTI) in adult women in October 2022. Enrollment is ongoing and expected to be completed in the first quarter of 2024. Iterum will conduct an interim analysis for sample size re-estimation as specified in its special protocol assessment (SPA) agreement with the FDA following achievement of 50% patient enrollment. The SPA agreement provides that the design and planned analysis of the trial, as set out in the protocol submitted to the FDA, adequately addresses the objectives necessary to support the potential resubmission of Iterum’s NDA for oral sulopenem for the treatment of uUTI.
• New Japanese Patent Issued: The Japanese Patent Office has issued a Certificate of Patent for Japanese Patent Registration No. 7295964 entitled “Combinations of Beta-Lactam Compounds and Probenecid and Uses Thereof” directed to the composition of the bilayer tablet of sulopenem etzadroxil and probenecid (oral sulopenem) and its preparation. This patent is scheduled to expire no earlier than 2039. In addition to in-licensed patents, Iterum also owns two U.S. patents for oral sulopenem, one directed to the composition of the bilayer tablet and its related uses, and the other directed to the method of use of oral sulopenem in treating multiple diseases, including uncomplicated urinary tract infections as well as a number of pending patent applications in the U.S. and other jurisdictions including Europe and China.

Second Quarter 2023 Financial Results

Cash, cash equivalents and short-term investments were $44.7 million as of June 30, 2023. Based on its current operating plan, Iterum expects that its current cash, cash equivalents and short-term investments will be sufficient to fund its operations into the third quarter of 2024. As of July 31, 2023, Iterum had approximately 13.0 million ordinary shares outstanding.

Research and development (R&D) expenses for the second quarter 2023 were $9.0 million, compared to $4.0 million for the same period in 2022. The increase for the three-month period was primarily due to an increase in costs incurred supporting Iterum’s REASSURE trial, which began enrollment in October 2022, partially offset by a reduction in share-based compensation expense.

General and administrative (G&A) expenses for the second quarter 2023 were $1.9 million, compared to $4.1 million for the same period in 2022. The decrease for the three-month period was primarily due to a reduction in share-based compensation expense, as well as a decrease in legal fees associated with the lawsuit filed in August 2021 and dismissed with prejudice in January 2023.

Net loss for the second quarter 2023 was $12.2 million, compared to a net loss of $6.7 million for the same period in 2022. Non-GAAP¹ net loss for the second quarter 2023 was $10.0 million, compared to a non-GAAP1 net loss of $5.7 million for the same period in 2022.

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, intangible asset amortization ($0.4 million and $0.9 million); share-based compensation expense ($0.1 million and $0.5 million); the interest expense associated with accrued interest on the 6.500% Exchangeable Senior Subordinated Notes due 2025 (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 $0.4 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $1.2 million); and the non-cash adjustments to the fair value of derivatives and the Limited Recourse Royalty-Linked Subordinated Notes (Royalty-Linked Notes) ($1.0 million and $1.8 million) for the three and six months ended June 30, 2023, respectively, and intangible asset amortization ($0.4 million and $0.9 million); share-based compensation expense ($2.0 million and $3.9 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 $0.4 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $1.2 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($2.2 million and $7.3 million) for the three and six months ended June 30, 2022, 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 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 six months ended June 30, 2023 and June 30, 2022. 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.
