-General Alignment with FDA on Key Aspects of Design of Proposed Additional Clinical Trial-
 -Cash Runway into 2024-

DUBLIN, Ireland and CHICAGO, May 13, 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 first quarter ended March 31, 2022.

“As reported earlier this week, we have reached general alignment with the U.S. Food and Drug Administration (“FDA”) on key aspects of the proposed design of an additional clinical trial comparing oral sulopenem to Augmentin^® (amoxicillin/clavulanate) for the treatment of uncomplicated urinary tract infection (“uUTI”) in adult women to support a potential resubmission of our new drug application (“NDA”) for oral sulopenem,” said Corey Fishman, Iterum’s Chief Executive Officer. “We plan to request an agreement with the FDA regarding the proposed protocol under the special protocol assessment (“SPA”) process. Subject to finalizing the SPA agreement with the FDA, we expect to initiate enrollment in the second half of 2022.”

Highlights and Recent Events

• Met with FDA: We reached general alignment with the FDA at a meeting in early May 2022 on key aspects of the design of an additional clinical trial required to support the potential resubmission of the NDA for oral sulopenem for uUTI.
• Reduced outstanding debt: We completed the repayment of our term loan with Silicon Valley Bank in March 2022.

First Quarter 2022 Financial Results

Cash, cash equivalents and short-term investments was $75.3 million at March 31, 2022. Based on the current operating plan, which includes the planned conduct of the additional Phase 3 clinical trial, Iterum expects that its current cash, cash equivalents and short-term investments will be sufficient to fund its operations into 2024. As of April 30, 2022, Iterum had approximately 183.4 million ordinary shares outstanding.

Research and development (R&D) expenses for the first quarter of 2022 were $3.4 million compared to $2.5 million for the same period in 2021. The increase was primarily due to the non-cash amortization of an intangible asset in 2022, trial start-up costs associated with the registrational trial expected to begin in the second half of 2022, higher personnel costs due to an increase in headcount to support additional clinical trial efforts and higher share-based compensation, partially offset by lower consulting spend.

General and administrative (G&A) expenses for the first quarter of 2022 were $3.9 million compared to $3.4 million for the same period in 2021. The increase was primarily due to an increase in share-based compensation expense, partially offset by lower consulting spend.

Adjustments to the fair value of derivatives for the first quarter of 2022 were $5.2 million compared to ($90.1) million for the same period in 2021. The non-cash adjustment in the first quarter of 2022 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, as well as a reduction in the liability associated with the Limited Recourse Royalty-Linked Subordinated Notes (the “Royalty-Linked Notes”) due to a change to the expected timing of payments. The non-cash adjustment in the first quarter of 2021 related to an increase in the value of the derivative components associated with the Exchangeable Notes and the Royalty-Linked Notes primarily as a result of an increase in the price of Iterum’s ordinary shares and an increase in Iterum’s market capitalization during the period.

Net loss for the first quarter of 2022 was $3.5 million compared to a net loss of $98.9 million for the same period in 2021. Non-GAAP¹ net loss of $5.6 million in the first quarter of 2022 was relatively flat compared to the non-GAAP¹ net loss of $5.8 million for the same period in 2021.

Upcoming Presentations

• Corporate presentation at the 2022 H.C. Wainwright Global Investment Conference to be held on Wednesday, May 25, 2022 at 11:30am ET

The purpose of this virtual public workshop, entitled “Development Considerations of Antimicrobial Drugs for the Treatment of Uncomplicated Urinary Tract Infections (uUTI),” is to discuss nonclinical and clinical considerations regarding developing antimicrobial drugs for the treatment of uUTI.

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 ($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 January 31, 2025 (“the Maturity Date”), whichever is earlier ($0.2 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($0.6 million); and the non-cash adjustments to the fair value of derivatives ($5.2 million) for the three months ended March 31, 2022, and share-based compensation expense ($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 the Maturity Date, whichever is earlier ($0.4 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($2.3 million); and the non-cash adjustments to the fair value of derivatives ($90.1 million) for the three months ended March 31, 2021.

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 Royalty-Linked Notes; and the non-cash adjustments to the fair value of derivatives for the three months ended March 31, 2022 and March 31, 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 and non-GAAP net loss per share to GAAP net loss per share have been provided in the tables included in this press release.
