On October 25, 2024, the U.S. Food and Drug Administration (FDA) approved Orlynvah™ (sulopenem etzadroxil and probenecid) tablets for the treatment of uncomplicated urinary tract infections (UTIs) caused by the microorganisms Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis in adult women who have limited or no alternative oral antibacterial treatment options. An uncomplicated UTI is a bacterial infection of the bladder in women with no structural abnormalities of the urinary tract. Up to half of women will experience an uncomplicated UTI in their lifetime. Orlynvah™ is a combination product that contains sulopenem etzadroxil, the antibacterial used to treat the infection, and probenecid, an ingredient that helps keep the antibiotic in the body longer. Orlynvah™ possesses potent activity against bacteria species that are often resistant to other antibiotic treatments. The recommended dosing of Orlynvah™ is one tablet twice daily for five days, taken with food.
The approval of Orlynvah™ for the treatment of uncomplicated UTIs was based on the results of two clinical trials that evaluated the safety and efficacy of ORLYNVAH™ compared to ciprofloxacin (SURE 1 trial) and amoxicillin/clavulanate (REASSURE trial) in the treatment of adult women with uncomplicated UTIs. In both studies, Orlynvah™ was well tolerated and resulted in a higher response rate. Orlynvah™ should not be prescribed to patients with gout, kidney stones, blood disorders or a known history of allergy to penicillin or cephalosporin antibiotics. The most common side effects are diarrhea, nausea, yeast infection, headache and vomiting.
