Iterum Therapeutics Reports Fourth Quarter and Full Year 2019 Financial Results

 --Topline data from cUTI and uUTI pivotal trials on track to report around the end of Q1--
--NDAs anticipated to file with the FDA in mid-2020--

DUBLIN, Ireland and CHICAGO, March 12, 2020 (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, 2019.

“2019 was a year of incredible progress for Iterum. We completed enrollment in all three Phase 3 clinical trials of sulopenem and reported topline results from our complicated intra-abdominal infections (cIAI) trial,” said Corey Fishman, Chief Executive Officer of Iterum Therapeutics plc.  “2020 is a pivotal year for the company.  We started the year by raising additional capital to fund the company through topline results of the remaining two Phase 3 studies, complicated urinary tract infections (cUTI) and uncomplicated urinary tract infections (uUTI), planned submission of two new drug applications (NDAs) to the U.S. Food and Drug Administration (FDA) and preparations for a potential commercial launch in 2021.”

2019 Highlights and Recent Events

• Completed enrollment in all Phase 3 pivotal clinical trials: In the fourth quarter of 2019, Iterum completed patient enrollment in its two remaining clinical trials, Sulopenem for Resistant Enterobacteriaceae (SURE) 1 in uUTI and SURE 2 in cUTI.  Overall, more than 3,700 patients were enrolled in our Phase 3 clinical trials of sulopenem since initiation in the third quarter of 2018.
• Announced topline results in first Phase 3 trial: In December 2019, Iterum announced that it narrowly missed the primary endpoint of its SURE 3 clinical trial cIAI.  While the trial narrowly missed the primary endpoint, we believe the secondary supporting analysis and safety data support the potential for sulopenem in the treatment of multi-drug resistant infections.
• Strengthened the balance sheet:  Iterum raised approximately $51.6 million ($46.7 million net of fees and expenses) in January 2020 through a private placement of units comprised of approximately (i) $51.6 million aggregate principal amount of its 6.500% exchangeable senior subordinated notes due 2025 and (ii) $0.1 million aggregate principal amount of its limited recourse royalty-linked senior subordinated notes.
• Filed two non-provisional patent applications with United States Patent and Trademark Office: One patent application addressed the effect of probenecid on the plasma concentrations of sulopenem after multi-day dosing and the second patent application related to a method of preparing a bilayer tablet composed of sulopenem etzadroxil and probenecid which resulted in an increase in the amount of sulopenem in the blood relative to dosing each agent in a separate formulation. If either patent is granted, it would provide 20 years of intellectual property protection for oral sulopenem from the date the non-provisional patent application was filed (to 2039). The current U.S. composition of matter patent on sulopenem etzadroxil expires in 2029 with potential extension to 2034 under the Hatch-Waxman Act.

Fourth Quarter and Full Year 2019 Financial Results

As of December 31, 2019, Iterum had cash and cash equivalents of $4.8 million and approximately 14.5 million shares outstanding. In January 2020, Iterum received net proceeds of $46.7 million from the private placement with accredited investors of 6.500% exchangeable senior subordinated notes due 2025 and limited recourse royalty-linked senior subordinated notes. Iterum expects that its current cash and cash equivalents, including the proceeds from this recent financing, will be sufficient to fund its operations into the second half of 2020.

Research and development (R&D) expenses for the fourth quarter and full year 2019 were $20.9 million and $90.8 million, respectively, compared to $21.5 million and $68.6 million for the same periods in 2018. The increases for both the three-month and twelve-month periods were primarily due to higher clinical trial expenses associated with the three Phase 3 clinical trials initiated in the third quarter of 2018, partially offset by milestone payments made to Pfizer Inc. of $7.5 million in the fourth quarter of 2018 and $15.0 million in the 2018 twelve-month period.

General and administrative (G&A) expenses for the fourth quarter and full year 2019 were $2.3 million and $11.3 million, respectively, compared to $2.7 million and $8.8 million for the same periods in 2018.  The increase for the full year was primarily due to increased costs associated with operating as a public company and additional headcount to support business activities.

For the fourth quarter and full year 2019, Iterum reported a net loss of $23.6 million and $103.1 million, respectively, compared to a net loss of $24.3 million and $77.1 million for the same periods in 2018.

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. If approved, sulopenem will help address the significant clinical and economic need for new oral antibiotics that enable the avoidance of hospitalization or facilitate early hospital discharge by providing continuity-of-care step-down therapy. The safety profile of IV sulopenem has been documented in a Phase 2 program. Oral and IV sulopenem are being evaluated in pivotal Phase 3 clinical trials of uncomplicated urinary tract infections, complicated urinary tract infections and complicated intra-abdominal infections.

The U.S. Food and Drug Administration (FDA) has granted Special Protocol Agreements (SPA) and Qualified Infectious Disease Product (QIDP) designations for oral and IV sulopenem in accordance with the Generating Antibiotics Incentives Now (GAIN) Act, which will provide five years of additional regulatory exclusivity and expedited Fast Track FDA review.
