TITLE: Tebipenem HBr for cUTI - NDA Submission
ClinicalTrial.gov (NCT03788967): Study to Assess the Efficacy, Safety and Pharmacokinetics of Orally Administered Tebipenem Pivoxil Hydrobromide (SPR994) Compared to Intravenous Ertapenem in Patients With Complicated Urinary Tract Infection (cUTI) or Acute Pyelonephritis (AP) (ADAPT-PO)

MECHANISM OF ACTION
Tebipenem HBr (tebipenem pivoxil hydrobromide; formerly SPR994) is Spero’s novel investigational oral formulation of tebipenem pivoxil, a carbapenem antibiotic of the β-lactam class marketed by Meiji Seika Pharma Co. Ltd. (Meiji) in Japan as Orapenem® since 2009 for pediatric infections limited to pneumonia, otitis media and sinusitis. Carbapenems are an important subclass of antibiotics because they have been observed to be safe and effective in the treatment of drug-resistant Gram-negative bacterial infections. Tebipenem HBr is being developed for the treatment of complicated urinary tract infections, including acute pyelonephritis. The Company expects that the favorable ADAPT-PO clinical trial results, once finalized, will support completion of a New Drug Application submission to the FDA in the second quarter of 2021. If approved, tebipenem HBr would be the first oral carbapenem antimicrobial to receive marketing approval in the United States. Tebipenem HBr has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the FDA for the treatment of cUTI and AP.
In 2007, in the United States alone, there were an estimated 10.5 million office visits for urinary tract infection (UTI) symptoms and 2-3 million emergency department visits. Most cases of cUTI and acute pyelonephritis are caused by Enterobacteriaceae, with Escherichia coli being the most common pathogen in the majority of infections across care settings. According to the Centers for Disease Control (CDC), drug-resistant Enterobacteriaceae, or commonly called extended-spectrum beta lactamase (ESBL) producing Enterobacteriaceae, is considered to be one of the most serious antibiotic-resistant bacterial threats in the United States. Antimicrobial resistance rates across most U.S. regions to fluoroquinolones, the most commonly used antibiotic for UTI, are >30% among Escherichia coli. Currently, there are few oral options to treat these patients. There is a need for strategies to avoid preventable cUTI-related inpatient and emergency department visits and potentially an opportunity to shift site of care for a proportion of hospitalized patients with cUTIs.
