Iterum Therapeutics Broadens Patent Estate for Oral Sulopenem


DUBLIN and CHICAGO, Aug. 02, 2024 (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 announced the United States Patent and Trademark Office (USPTO) has issued a notice allowance for two U.S. patents and the Canadian Intellectual Property Office (CIPO) has issued a Canadian patent, all related to sulopenem etzadroxil and probenecid (oral sulopenem).

“We are very pleased to continue to strengthen our oral sulopenem patent estate further with the addition of these new patents and extending existing protection to cover Canada,” said Corey Fishman, Chief Executive Officer.

The USPTO has issued Iterum a Notice of Allowance for U.S. patent application number 18/065,400 entitled “Combinations of Beta-Lactam Compounds and Probenecid and Uses Thereof” that covers the use of Iterum's candidate combination of sulopenem etzadroxil and probenecid in treating uncomplicated urinary tract infection. This Notice of Allowance concludes the substantive examination of the patent application and will result in the issuance of a U.S. patent after administrative processes are completed. The U.S. patent scheduled to issue from this application will expire April 1, 2039, absent any extensions.

The USPTO has also issued Iterum a Notice of Allowance for U.S. patent application number 17/198,335 entitled “Combinations of Beta-Lactam Compounds, Probenecid, and Valproic Acid and Uses Thereof” that covers the use of sulopenem etzadroxil, probenecid, and valproic acid in treating specified infections. This Notice of Allowance concludes the substantive examination of the patent application and will result in the issuance of a U.S. patent after administrative processes are completed. The U.S. patent scheduled to issue from this application will expire March 11, 2041, absent any extensions.

The CIPO issued Iterum a Notice of Allowance for Canadian patent application number 3129337 entitled “Combinations of Beta-Lactam Compounds and Probenecid and Uses Thereof” that covers a bilayer tablet comprising sulopenem etzadroxil and probenecid, methods of preparing the bilayer tablet, and the use of the bilayer tablet in treating specified diseases. This Notice of Allowance concludes the substantive examination of the patent application and will result in the issuance of a Canadian patent after administrative processes are completed. The Canadian patent scheduled to issue from this application will expire December 23, 2039, absent any extensions.

Iterum’s patent portfolio also contains pending patent applications in a number of other jurisdictions 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.
