DUBLIN, Ireland and CHICAGO, March 28, 2024 (GLOBE NEWSWIRE) — Iterum Therapeutics plc (Nasdaq: ITRM), 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 fourth quarter and year ended December 31, 2023.

“Since we announced positive topline data from our REASSURE trial in January, we’ve made significant progress in completing the new drug application (NDA) for the planned resubmission early in the second quarter,” said Corey Fishman, Iterum’s Chief Executive Officer. “We believe the strong results from this trial, which was conducted under a Special Protocol Assessment (SPA) agreement with the U.S. Food and Drug Administration (FDA), address the FDA’s recommendations for additional data to support approval of oral sulopenem for the treatment of adult women with uncomplicated urinary tract infections (uUTIs). The potential approval of sulopenem would mark the first oral penem approved in the U.S., and the first antibiotic approved for the treatment of uUTIs in over 25 years.”

Highlights and Recent Events

• Preparation of NDA Underway: 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 uUTIs in adult women in October 2022 and completed enrollment in October 2023 enrolling 2,222 patients. Iterum reported positive top-line data in January 2024 and plans to resubmit its NDA early in the second quarter of 2024. Provided that the resubmitted NDA addresses all of the deficiencies identified in the Complete Response Letter (CRL), Iterum expects that the FDA will complete its review and take action six months from the date the FDA receives the resubmitted NDA (or early in the fourth quarter of 2024).

• Extended Cash Runway: Subsequent to December 31, 2023, through February 29, 2024, Iterum sold 2.9 million ordinary shares under an at-the-market offering (ATM) agreement, at an average price of $2.52 per share for net proceeds of $7.1 million, which has extended cash runway into 2025 based on its current operating plan. As of February 29, 2024, Iterum had approximately 16.4 million ordinary shares outstanding.

• Engaged Financial Advisor: As previously disclosed, after receiving positive data from the REASSURE trial, Iterum’s board of directors determined that Iterum should focus on a strategic process to sell, license, or otherwise dispose of its rights to sulopenem with the goal of maximizing shareholder value. In connection with this strategic process, Iterum has engaged a financial advisor to assist management and the board in evaluating strategic alternatives. There can be no assurance that its exploration will result in Iterum pursuing a transaction or that any transaction, if pursued, will be completed on attractive terms, if at all. Iterum’s board of directors has not set a timetable for completion of this evaluation process and does not intend to disclose further developments unless and until it is determined that further disclosure is appropriate or necessary.

Fourth Quarter and Full Year 2023 Financial Results

Cash, cash equivalents and short-term investments were $23.9 million at December 31, 2023. Based on the current operating plan, Iterum expects that its current cash, cash equivalents and short-term investments, including amounts raised under an ATM offering subsequent to year-end through February 29, 2024, will be sufficient to fund its operations into 2025, including through the expected Prescription Drug User Fee Act date early in the fourth quarter of 2024.

Research and development (R&D) expenses for the fourth quarter and full year 2023 were $9.7 million and $40.0 million, respectively, compared to $5.8 million and $17.6 million for the same periods in 2022. The increase for the three-month period was primarily due to an increase in costs to support Iterum’s REASSURE trial, partially offset by a decrease in CMC related expenses due to the write-off of a valuation allowance held against a research and development tax credit. The increase in R&D expenses for the full year was primarily due to the REASSURE trial, partially offset by a decrease in share-based compensation expense and the previously mentioned write-off of a valuation allowance.

General and administrative (G&A) expenses for the fourth quarter and full year 2023 were $1.7 million and $7.5 million, respectively, compared to $2.1 million and $12.8 million for the same periods in 2022. The decrease for the three-month period was primarily due to a decrease in legal fees and insurance costs. The decrease for the full year was primarily due to lower share-based compensation expense for employees and directors, lower insurance costs, lower rent expense and a decrease in legal fees associated with the lawsuit filed in August 2021 which was dismissed with prejudice in January 2023.

Adjustments to the fair value of derivatives for the fourth quarter and full year 2023 were ($0.3 million) and $11.1 million, compared to $3.0 million and $5.5 million for the same periods in 2022. The non-cash adjustment for the full year 2023 primarily related to a decrease in the fair value of the Limited Recourse Royalty-Linked Subordinated Notes (the “Royalty-Linked Notes”) due to a reduction in management’s revenue forecast of U.S. sulopenem sales. The non-cash adjustment in the fourth quarter and full year 2022 primarily related to a decrease in the value of the derivative components associated with Iterum’s 6.500% Exchangeable Senior Subordinated Notes due 2025 (the “Exchangeable Notes”) as a result of a decrease in the price of its ordinary shares and market capitalization during the period. In addition, during the fourth quarter of 2022, a change in the discount rate impacted the fair value of the Royalty-Linked Notes.

Cancellation of share options for the full year 2022 was $17.4 million and related to the non-cash charge in connection with employee share options that were surrendered and cancelled in July 2022.

Net loss for the fourth quarter and full year 2023 was $12.4 million and $38.4 million, respectively, compared to a net loss of $5.1 million and $44.4 million for the same periods in 2022. Non-GAAP1 net loss for the fourth quarter and full year 2023 of $10.7 million and $43.8 million, respectively, compared to a non-GAAP¹ net loss of $6.4 million and $22.9 million for the same periods 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 $1.7 million); share-based compensation expense ($0.1 million and $0.8 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 $0.8 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $2.4 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes (($0.3 million) and $11.1 million) for the three and twelve months ended December 31, 2023, respectively, and intangible asset amortization ($0.4 million and $1.7 million); share-based compensation expense ($0.5 million and $4.8 million); the non-cash cancellation expense of share options ($0.0 million and $17.4 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 $0.8 million); the non-cash amortization of the Exchangeable Notes ($0.6 million and $2.4 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($3.0 million and $5.5 million) for the three and twelve months ended December 31, 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) / 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) / income, which is the most directly comparable GAAP measure, adjusted to exclude intangible asset amortization; share-based compensation expense; the non-cash expense for the cancellation of share options; 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 twelve months ended December 31, 2023 and December 31, 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.
