What Is Sulopenem Etzadroxil And Probenecid Used For?
1 INDICATIONS AND USAGE ORLYNVAH, a combination of sulopenem etzadroxil, a penem antibacterial, and probenecid, a renal tubular transport inhibitor, is indicated for the treatment of uncomplicated urinary tract infections (uUTI) 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. ( 1.1 ) Limitations of Use ORLYNVAH is not indicated for the treatment of: Complicated urinary tract infections (cUTI) or as step-down treatment after intravenous antibacterial treatment of cUTI. ( 1.1 , 14.2 ) Complicated intra-abdominal infections (cIAI) or as step-down treatment after intravenous antibacterial treatment of cIAI. ( 1.1 , 14.3 ) Usage to Reduce Development of Drug-Resistant Bacteria To reduce the development of drug-resistant bacteria and maintain the effectiveness of ORLYNVAH and other antibacterial drugs, ORLYNVAH should be used only to treat uUTI that are proven or strongly suspected to be caused by susceptible bacteria. Culture and susceptibility information should be utilized in selecting or modifying antibacterial therapy. ( 1.2 , 5.5 ) 1.1 Uncomplicated Urinary Tract Infections ORLYNVAH is indicated for the treatment of uncomplicated urinary tract infections (uUTI) 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. Limitations of Use ORLYNVAH is not indicated for the treatment of: Complicated urinary tract infections (cUTI) or as step-down treatment after intravenous antibacterial treatment of cUTI [see Clinical Studies ( 14.2 )]. Complicated intra-abdominal infections (cIAI)) or as step-down treatment after intravenous antibacterial treatment of cIAI [see Clinical Studies ( 14.3 )]. 1.2 Usage to Reduce Development of Drug-Resistant Bacteria To reduce the development of drug-resistant bacteria and maintain the effectiveness of ORLYNVAH and other antibacterial drugs, ORLYNVAH should be used only to treat uUTI that are proven or strongly suspected to be caused by susceptible bacteria. Culture and susceptibility information should be utilized in selecting or modifying antibacterial therapy [see Warnings and Precautions ( 5.5 )].

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in the Warnings and Precautions section. Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Clostridioides difficile -Associated Diarrhea [see Warnings and Precautions ( 5.2 )] Risk of Uric Acid Kidney Stone Development [see Warnings and Precautions ( 5.3 )] Exacerbation of Gout [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (≥2%) in patients treated with ORLYNVAH were diarrhea, nausea, vulvovaginal mycotic infection, headache, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Iterum Therapeutics at 1-866-414-SULO or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect rates observed in practice. ORLYNVAH was evaluated in two Phase 3 controlled, multinational, randomized, double blind, double dummy clinical trials (Trial 1 and Trial 2) in adult women with uUTI. Therapy with oral ORLYNVAH tablets was administered as one tablet twice daily for 5 days [see Clinical Studies ( 14 )]. The trials included 1932 patients treated with ORLYNVAH and 1929 patients treated with comparator antibacterial drugs (ciprofloxacin or amoxicillin/clavulanate). The median age of patients treated with ORLYNVAH was 50 years, ranging between 18 and 91 years old. Patients treated with ORLYNVAH were all female (100%), predominantly White (83%) and from the United States (83%). Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation Serious adverse reactions occurred in 6/1932 (0.3%) of uUTI patients treated with ORLYNVAH and in 2/822 (0.2%) and 5/1107 (0.5%) of patients treated with ciprofloxacin or amoxicillin/clavulanate, respectively. Treatment discontinuation due to an adverse reaction occurred in 21/1932 (1%) of patients treated with ORLYNVAH, 8/822 (1%) of patients treated with ciprofloxacin, and 4/1107 (0.4%) of patients treated with amoxicillin/clavulanate. The most commonly reported adverse reactions leading to discontinuation of ORLYNVAH were nausea (6/1932; 0.3%), diarrhea (5/1932; 0.3%), as well as abdominal pain, gastroesophageal reflux disease, vomiting, and dizziness, each 0.2% (3/1932). Most Common Adverse Reactions Adverse reactions occurring at 2% or greater in patients receiving ORLYNVAH were diarrhea, nausea, vulvovaginal mycotic infection, headache, and vomiting. Table 1 lists adverse reactions reported in ≥1% of patients receiving ORLYNVAH in the phase 3 uUTI trials (Trial 1 and Trial 2). The most common adverse reactions in patients treated with ORLYNVAH were diarrhea (10%) and nausea (4%). Table 1.

Drug Interactions
7 DRUG INTERACTIONS Ketoprofen : Concomitant use is not recommended ( 7.1 ) See full prescribing information for additional clinically significant drug interactions with ORLYNVAH ( 7.1 ) 7.1 Potential for ORLYNVAH to Affect Other Drugs Probenecid (a component of ORLYNVAH) is an inhibitor of organic anion transporters 1 and 3 (OAT1/3) and may increase plasma concentrations of drugs that are dependent on OAT1/3 for elimination. Table 2 provides a list of established or potentially clinically significant drug interactions. Table 2. Established and Other Potentially Clinically Significant Drug Interactions Concomitant Drug/Drug Class Effect on Drug Concentration Recommendation Ketorolac tromethamine ↑ ketorolac tromethamine Contraindicated Ketoprofen ↑ ketoprofen Concomitant use is not recommended. Indomethacin ↑ indomethacin May increase the risk of adverse reactions. Refer to drug-specific prescribing information for dosage adjustment instructions. Naproxen ↑ naproxen May increase the risk of adverse reactions. Refer to drug-specific prescribing information for dosage adjustment instructions. Methotrexate ↑ methotrexate If concomitant use cannot be avoided, monitor more frequently for adverse reactions associated with methotrexate as recommended in its prescribing information. Rifampin ↑ rifampin Monitor more frequently for adverse reactions associated with rifampin as recommended in its prescribing information. Lorazepam ↑ lorazepam Follow the recommended lorazepam dosage modifications outlined in its prescribing information. Oral Sulfonylureas ↑ antidiabetic Monitor more frequently for hypoglycemia. Follow recommended sulfonylurea dosage modifications in its prescribing information. Valproic Acid No valproic acid dosage adjustment is recommended when used concomitantly with ORLYNVAH. No clinically significant reduction in plasma valproic acid concentrations was observed following concomitant use with ORLYNVAH [see Clinical Pharmacology ( 12.3 )] . 7.2 Potential for Other Drugs to Affect ORLYNVAH Sulopenem is a substrate of OAT3; therefore, drugs that inhibit OAT3 may increase sulopenem plasma concentrations [see Clinical Pharmacology ( 12.3 )]. If concomitant use with ORLYNVAH is necessary, monitor more frequently for adverse reactions associated with ORLYNVAH (e.g., diarrhea and nausea) [see Adverse Reactions ( 6.1 )]. 7.3 Drug/Laboratory Interactions Treatment with ORLYNVAH may interfere with copper sulfate urine glucose tests, resulting in false-positive readings for glycosuria. Suspected glycosuria should be confirmed by using a test specific for glucose. Falsely high readings for theophylline have been reported in an in vitro study, using the Schack and Waxler technique, when therapeutic concentrations of theophylline and probenecid (a component of ORLYNVAH) were added to human plasma.
Contraindications
4 CONTRAINDICATIONS ORLYNVAH is contraindicated in patients with:
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Sulopenem Etzadroxil There are no available data on sulopenem etzadroxil use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Sulopenem etzadroxil was orally administered during organogenesis in embryo-fetal studies in mice, rats, and rabbits. In pregnant mice, maternal toxicity and an increased litter incidence of a fetal malformation, cleft palate, was observed with an oral dose of sulopenem etzadroxil associated with plasma sulopenem exposure approximately 23 times the clinical sulopenem exposure for the maximum recommended human dose (MRHD) of 1000 mg/day sulopenem etzadroxil. In pregnant rats and rabbits, orally administered sulopenem etzadroxil was not associated with fetal malformations at any dose, but in rats, maternal toxicity and reduced fetal body weights occurred at sulopenem etzadroxil doses associated with sulopenem plasma exposures approximately 2 and 6 times, respectively, the clinical sulopenem exposure for the MRHD of sulopenem etzadroxil. In rabbits, maternal toxicity and reduced fetal body weights occurred at sulopenem etzadroxil doses associated with sulopenem plasma exposures approximately 0.1 and 0.2 times, respectively, the clinical sulopenem exposure for the MRHD of sulopenem etzadroxil. Probenecid Available published data over several decades of probenecid use in pregnant woman have not identified a drug-associated risk of miscarriage, major birth defects, or adverse maternal or fetal outcomes. Probenecid crosses the placental barrier and appears in cord blood. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%,...
