--Registration Trial for uUTI Ongoing and On Track--

--Cash Runway until Mid-2024--

DUBLIN, Ireland and CHICAGO, May 12, 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 first quarter ended March 31, 2023.

“We remain on track to complete enrollment in our REASSURE trial in the first half of next year with over 100 sites currently open to enrollment and a plan to add another 40-70 clinical trial sites,” said Corey Fishman, Iterum’s Chief Executive Officer. “Top-line data is expected soon after enrollment is completed, 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 half of 2024. An interim analysis at 50% patient enrollment is expected to occur in the second half of 2023. This trial is being conducted under a special protocol assessment (SPA) agreement with the FDA. 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.
  
  
• Presented DOOR analysis at ECCMID: Iterum presented scientific posters at ECCMID 2023 highlighting the application of the desirability of outcome ranking (DOOR) to two registration trials. The DOOR methodology, utilized recently by the Antibacterial Resistance Leadership Group to develop a method to evaluate data from completed pivotal complicated urinary tract infection (cUTI) trials, when applied retrospectively to Iterum’s two Phase 3 studies of sulopenem, one each in cUTI and uUTI, respectively, demonstrated that oral sulopenem was comparably more effective than ciprofloxacin in patients with uUTI and provided comparable efficacy to ertapenem in patients with cUTI. This novel method of analyzing data from clinical trials taking into account both benefits and harms of drugs being evaluated and providing an assessment of the patient experience has not yet been accepted by regulatory authorities as a primary endpoint for UTI studies.
  

First Quarter 2023 Financial Results

Cash, cash equivalents and short-term investments were $51.8 million as of March 31, 2023. Based on the current operating plan, Iterum expects that its current cash, cash equivalents and short-term investments will be sufficient to fund its operations until mid-2024. As of April 30, 2023, we had approximately 12.9 million ordinary shares outstanding.

Research and development (R&D) expenses for the first quarter 2023 were $6.4 million, compared to $3.4 million for the same period in 2022. The increase for the three-month period was primarily due to an increase in costs to support our 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 first quarter 2023 were $2.1 million, compared to $3.9 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 first quarter 2023 was $9.9 million, compared to a net loss of $3.5 million for the same period in 2022. Non-GAAP¹ net loss for the first quarter 2023 of $7.4 million, compared to a non-GAAP1 net loss of $5.6 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); share-based compensation expense ($0.4 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 January 31, 2025 (the Maturity Date), whichever is earlier ($0.2 million); the non-cash amortization of the Exchangeable Notes ($0.6 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($0.9 million) for the three months ended March 31, 2023, and intangible asset amortization ($0.4 million); share-based compensation expense ($1.9 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); the non-cash amortization of the Exchangeable Notes ($0.6 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($5.2 million) for the three months ended March 31, 2022.

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 months ended March 31, 2023 and March 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.
