Share

FDA has approved an Iterum Therapeutics NDA for Orlynvah (sulopenem etzadroxil and probenecid) for treating uncomplicated urinary tract infections (uUTIs) caused by the designated microorganisms Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis in adult women who have limited or no alternative oral antibacterial treatment options.

Approval was based on data from two Phase 3 clinical trials (SURE 1 and REASSURE) that evaluated the safety and efficacy of Orlynvah compared to ciprofloxacin (SURE 1) and Augmentin (REASSURE) in the treatment of adult women with uUTI. “SURE 1 showed superiority to ciprofloxacin in fluoroquinolone resistant infections, while REASSURE showed non-inferiority and statistical superiority to Augmentin in the Augmentin susceptible population,” the company says.

Orlynvah is described as a novel oral penem antibiotic that possesses potent activity against species of Enterobacterales including those that encode extended spectrum beta-lactamase or AmpC-type beta-lactamases that often show resistance to third generation cephalosporins.
