Cilastatin, Imipenem and Relebactam

RECARBRIO is a combination of imipenem, a penem antibacterial, cilastatin, a renal dehydropeptidase inhibitor, and relebactam, a beta-lactamase inhibitor, indicated in adult and pediatric patients weighing at least 2 kg for the treatment of the following infections caused by susceptible gram-negative microorganisms: Hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP). Complicated urinary tract infections, including pyelonephritis (cUTI) in patients who have limited or no alternative treatment options. Complicated intra-abdominal infections (cIAI) in patients who have limited or no alternative treatment options. Approval of the cUTI and cIAI indications is based on limited clinical safety and efficacy data for RECARBRIO.

RECARBRIO is an antibacterial drug.

Adult Patients: The recommended dosage of RECARBRIO is 1.25 grams (imipenem 500 mg, cilastatin 500 mg, relebactam 250 mg) administered by intravenous (IV) infusion over 30 minutes every 6 hours to adult patients with creatinine clearance (CLcr) 90 mL/min or greater. Pediatric Patients weighing at least 2 kg: The recommended dosage of RECARBRIO for pediatric patients weighing at least 2kg varies by patient weight and age, with specific dosing recommendations as shown in the table below,: Recommended Dosage of RECARBRIO In Pediatric Patients Weighing at Least 2 kg Age Range Body Weight Dose Dosing Frequency Infusion Duration Birth Pediatric patients from birth (includes pediatric patients at least 37 weeks post-menstrual age) to less than 3 months 2 kg or greater RECARBRIO

RECARBRIO is contraindicated in patients with a history of known severe hypersensitivity (severe systemic allergic reaction such as anaphylaxis) to any component of RECARBRIO. RECARBRIO is contraindicated in patients with a history of known severe hypersensitivity to any component of RECARBRIO.

Hypersensitivity Reactions: Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta lactam drugs. Discontinue RECARBRIO immediately if a hypersensitivity reaction occurs. Seizures and Central Nervous System Adverse Reactions: CNS adverse reactions such as seizures have been reported with imipenem/cilastatin, a component of RECARBRIO. If focal tremors, myoclonus, or seizures occur, evaluate patients, to determine whether RECARBRIO should be discontinued. Increased Seizure Potential Due to Interaction with Valproic Acid: Concomitant use of RECARBRIO with valproic acid or divalproex sodium may reduce the serum concentration of valproic acid which may increase the risk of breakthrough seizures. Avoid concomitant use or consider alternative antibacterial drugs other than carbapenems.

The following serious adverse reactions are described in greater detail in the Warnings and Precautions section. Hypersensitivity Reactions Seizures and Other Central Nervous System Adverse Reactions Increased Seizure Potential Due to Interaction with Valproic Acid Clostridioides difficile -Associated Diarrhea (CDAD) Adult HABP/VABP Patients: The most frequently reported adverse reactions occurring in greater than or equal to 5% of patients treated with RECARBRIO were aspartate aminotransferase increased, anemia, alanine aminotransferase increased, diarrhea, hypokalemia, and hyponatremia.

Ganciclovir: Avoid concomitant use. Valproic Acid or Divalproex Sodium: Avoid concomitant use. Ganciclovir Generalized seizures have been reported in patients who received ganciclovir concomitantly with imipenem/cilastatin, a component of RECARBRIO. Ganciclovir should not be used concomitantly with RECARBRIO unless the potential benefits outweigh the risks.

Store RECARBRIO vials at 20°C to 25°C (68°F to 77°F), excursions permitted between 15°C to 30°C (between 59°F to 86°F).
