--Patient Enrollment in Registration Trial for uUTI Underway--

--Cash Runway into 2024--

DUBLIN, Ireland and CHICAGO, Nov. 10, 2022 (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 third quarter ended September 30, 2022.

“We are thrilled to have the REASSURE clinical trial underway,” said Corey Fishman, Chief Executive Officer. “We are one step closer to potentially bringing oral sulopenem to market as a viable treatment option for health care providers and patients impacted by the lack of available antibiotics to fight against growing bacterial resistance in infections found in the community. We also continue to look forward and see utility in developing sulopenem for the treatment of diseases beyond urinary tract infections, particularly respiratory infections.”

Highlights and Recent Events

• Initiation of REASSURE Clinical Trial: 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 expected to be completed in the first half of 2024. This trial is being conducted under a Special Protocol Assessment (“SPA”) agreement with the U.S. Food and Drug Administration (“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 new drug application (“NDA”) for oral sulopenem.
   
• U.S. Patent Issued Extending Protection: The United States Patent and Trademark Office (“USPTO”) has issued Iterum a new patent, No. US 11,478,428, directed to the composition of the bilayer tablet of sulopenem etzadroxil and probenecid (“oral sulopenem”) and its related uses. The U.S. patent is scheduled to expire no earlier than 2039, absent any extensions. Existing patent protection for sulopenem etzadroxil is scheduled to expire in 2029, subject to potential extension. Iterum’s patent portfolio also contains pending patent applications outside the U.S., including Europe and China, submitted following receipt of the Written Opinion of the International Search Authority indicating that several claims directed to the composition of the bilayer tablet of oral sulopenem are novel and inventive.
   
• Regained Compliance with NASDAQ Bid Price Rule: On August 31, 2022, Iterum regained compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2) (“Bid Price Rule”) for continued listing on The Nasdaq Capital Market. In order to regain compliance with the Bid Price Rule, on August 17, 2022, Iterum effected a 1-for-15 reverse share split (“Reverse Share Split”) of its outstanding ordinary shares. Accordingly, all authorized and issued and authorized and unissued ordinary shares, 6.500% Exchangeable Senior Subordinated Notes due 2025 (“Exchangeable Notes”), share options, restricted share units, warrants and shares reserved for future issuance under Iterum's share plans have been adjusted in the Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on November 10, 2022 to reflect the Reverse Share Split for all prior periods presented.

Third Quarter 2022 Financial Results

Cash, cash equivalents and short-term investments were $64.3 million at September 30, 2022. 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 into 2024, including through topline data from the REASSURE clinical trial. As of October 31, 2022, Iterum had approximately 12.2 million ordinary shares outstanding.

Research and development (“R&D”) expenses for the third quarter of 2022 were $4.4 million compared to $1.8 million for the same period in 2021. The increase was primarily due to an increase in costs incurred to support the activities for the REASSURE clinical trial.

General and administrative (“G&A”) expenses for the third quarter of 2022 were $2.7 million compared to $3.0 million for the same period in 2021. The decrease was primarily due to lower share-based compensation expense, partially offset by an increase in legal fees associated with the class action lawsuit filed in August 2021.

Adjustments to the fair value of derivatives for the third quarter of 2022 were $4.8 million compared to $9.8 million for the same period in 2021. The non-cash adjustment in the third quarter of 2022 related to an increase in the fair value of the Limited Recourse Royalty-Linked Subordinated Notes (the “Royalty-Linked Notes”) due to the newly issued patent directed to oral sulopenem to the composition of the bilayer tablet which provides patent protection at least until 2039, partially offset by a decrease in the value of the derivative components associated with Iterum’s Exchangeable Notes, primarily as a result of a decrease in the price of our ordinary shares and our market capitalization during the period. The non-cash adjustment in the third quarter of 2021 primarily related to a decrease in the value of the derivative components associated with the Exchangeable Notes as a result of a decrease in the price of its ordinary shares and market capitalization during the period, partially offset by an increase in the fair value of the Royalty-Linked Notes.

Cancellation of share options for the third quarter of 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 third quarter of 2022 was $29.1 million compared to net income of $3.7 million for the same period in 2021. Non-GAAP¹ net loss was $5.3 million in the third quarter of 2022 compared to the non-GAAP¹ net loss of $3.7 million for the same period in 2021.

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) / income and GAAP net (loss) / income per share, intangible asset amortization ($0.4 million and $1.3 million); share-based compensation expense ($0.4 million and $4.3 million); the cancellation of share options ($17.4 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 January 31, 2025 (“the Maturity Date”), whichever is earlier ($0.2 million and $0.6 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($0.6 million and $1.8 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($4.8 million and $2.5 million) for the three and nine months ended September 30, 2022, respectively, and share-based compensation expense ($1.5 million and $2.4 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 $0.9 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($0.6 million and $3.5 million); and the non-cash adjustments to the fair value of derivatives and Royalty-Linked Notes ($9.8 million and $64.5 million) for the three and nine months ended September 30, 2021, 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 Royalty-Linked 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, 2022 and September 30, 2021. 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 Therapeutics 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) / income and non-GAAP net loss per share to GAAP net (loss) / income per share have been provided in the tables included in this press release.
