FDA Review of NDA for Oral Sulopenem Continues;
Current Prescription Drug User Fee Act (PDUFA) date of July 25, 2021

Cash Runway into First Half of 2023

Company to host conference call today at 8:30am ET

DUBLIN, Ireland and CHICAGO, May 14, 2021 (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 first quarter ended March 31, 2021.

“We continue to prepare for a U.S. Food and Drug Administration (FDA) advisory committee meeting and look forward to clarity from the FDA on timing. In the meantime, the FDA continues its review of our new drug application (NDA) for oral sulopenem for the treatment of uncomplicated urinary tract infections (uUTI) in patients with a quinolone non-susceptible organism and has not advised us of any change to the current PDUFA goal date of July 25, 2021,” said Corey Fishman, Chief Executive Officer. “With an FDA decision on oral sulopenem expected in the second half of 2021 and a strong cash position, we are preparing for a launch of oral sulopenem into the community in the fourth quarter of 2021, if approved.”

Highlights and Recent Events

• NDA priority review by the FDA is ongoing with current PDUFA goal date of July 25, 2021: In January 2021, the FDA accepted for review our NDA for uUTI in patients with a quinolone non-susceptible organism. The FDA has designated our application as a priority review and consequently assigned a PDUFA goal date for completion of the review of oral sulopenem of July 25, 2021. The FDA previously planned to hold an advisory committee meeting for oral sulopenem on June 2, 2021 but this meeting was postponed to allow the FDA more time to review material provided by the Company in support of the NDA. A new date for such meeting, if required by the FDA, has not yet been confirmed.
• Extended cash runway into first half of 2023: In February 2021, we received total net proceeds of $74.3 million from an underwritten public offering and a registered direct offering. Based on our current operating plans, we believe our cash, cash equivalents and short-term investments of $100.5 million as of March 31, 2021 allows us to operate into the first half of 2023. As of March 31, 2021, we had approximately 179.1 million ordinary shares outstanding.
• Ongoing collaboration with a third-party provider of commercialization services: In February 2021, we engaged EVERSANA™, a leading provider of commercial services to the life science industry, and we have initiated pre-launch activities. We are in the process of finalizing an agreement with EVERSANA™ to provide commercialization services to launch oral sulopenem, if approved.

First Quarter 2021 Financial Results

As of March 31, 2021, Iterum had cash, cash equivalents and short-term investments of $100.5 million. 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 first half of 2023.

Research and development expenses for the first quarter of 2021 were $2.5 million compared to $9.7 million for the same period in 2020. The decrease for the period was primarily due to the completion of our Phase 3 clinical trials in 2020.

General and administrative (G&A) expenses for the first quarter of 2021 were $3.4 million compared to $3.2 million for the same period in 2020. The increase for the period was primarily due to higher spend on pre-commercialization activities and consultants to support our G&A function, partially offset by lower G&A headcount.

Adjustments to the fair value of derivatives for the first quarter 2021 were $90.1 million compared to $1.7 million for the same period in 2020. This non-cash adjustment in the first quarter of 2021 related to an increase in the value of the derivative components associated with Iterum’s 6.500% Exchangeable Senior Subordinated Notes due 2025 (the Exchangeable Notes) and Limited Recourse Royalty-Linked Subordinated Notes (the Royalty-Linked Notes) issued in 2020 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.

For the first quarter of 2021, Iterum reported a net loss of $98.9 million compared to a net loss of $16.1 million for the same period in 2020 due largely to non-cash adjustments to the derivative liabilities associated with Iterum’s Exchangeable Notes and Royalty-Linked Notes. Iterum reported non-GAAP net loss¹ of $6.1 million for the first quarter of 2021 compared to non-GAAP net loss of $13.4 million for the same period in 2020.

About Sulopenem

Sulopenem, a novel penem anti-infective compound with oral and IV formulations, has demonstrated potent in vitro activity against a wide variety of gram-negative, gram-positive and anaerobic bacteria resistant to other antibiotics. We believe that sulopenem and oral sulopenem have the potential to be important new treatment alternatives to address the growing concerns related to antibacterial resistance without the known toxicities of some of the most widely used antibiotics, specifically fluoroquinolones. Our NDA for oral sulopenem for the treatment of uUTI in patients with a quinolone non-susceptible pathogen is under FDA review and has a current PDUFA goal date of July 25, 2021.

Non-GAAP Financial Measures

To supplement Iterum Therapeutics’ financial results presented in accordance with U.S. generally accepted accounting principles, or GAAP, Iterum Therapeutics presents non-GAAP adjusted net loss and non-GAAP net loss per share to exclude from reported GAAP net loss and GAAP net loss per share for the three months ended March 31, 2021 and March 31, 2020, the interest expense associated with accrued interest on the Exchangeable Notes, or ENs, payable in cash, shares or a combination of both upon exchange, redemption or at January 31, 2025, or the Maturity Date, whichever is earlier ($0.436 million); the non-cash amortization of the ENs and Royalty-Linked Notes ($2.312 million); and the non-cash adjustments to the fair value of derivatives ($90.103 million) for the three months ended March 31, 2021, the interest expense associated with accrued interest on the Exchangeable Notes, or ENs, payable in cash, shares or a combination of both upon exchange, redemption or at January 31, 2025, or the Maturity Date, whichever is earlier ($0.652 million); the non-cash amortization of the ENs and Royalty-Linked Notes ($1.613 million); one-time, non-capitalized financing transaction costs ($2.130 million); and the offsetting non-cash adjustments to the fair value of derivatives ($1.679 million) for the three months ended March 31, 2020.

Iterum Therapeutics believes that the presentation of non-GAAP adjusted 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 Therapeutics’ management in assessing Iterum Therapeutics’ performance and results from period to period. These non-GAAP financial measures closely align with the way management measures and evaluates Iterum Therapeutics’ 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 adjusted 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 the interest expense associated with accrued interest on the ENs 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 ENs and Royalty-Linked Notes; one-time, non-capitalized financing transaction costs and the non-cash adjustments to the fair value of derivatives for the three months ended March 31, 2021 and March 31, 2020. Because of the non-standardized definitions of non-GAAP financial measures, non-GAAP adjusted net loss and non-GAAP net loss per share used by Iterum Therapeutics in the accompanying press release and tables therein 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 adjusted 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 the accompanying press release.
