Indication

PREZCOBIX® is indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus (HIV-1) infection in treatment-naïve and treatment-experienced adults with no darunavir resistance-associated substitutions (V11I, V32I, L33F, I47V, I50V, I54L, I54M, T74P, L76V, I84V, L89V).

Important Safety Information For PREZCOBIX®

Contraindications

  • Do not coadminister PREZCOBIX® and the following drugs due to the potential for serious and/or life-threatening events or loss of therapeutic effect: alfuzosin, carbamazepine, cisapride, colchicine, dihydroergotamine, dronedarone, elbasvir/grazoprevir, ergotamine, lovastatin, lurasidone, methylergonovine, oral midazolam, phenobarbital, phenytoin, pimozide, ranolazine, rifampin, St. John’s Wort (Hypericum perforatum), sildenafil for pulmonary arterial hypertension, simvastatin, and triazolam.

Warnings and Precautions

  • Hepatotoxicity: Patients with pre-existing liver dysfunction, including chronic active hepatitis B or C, have an increased risk for liver function abnormalities, including severe hepatic adverse reactions. Drug-induced hepatitis and cases of liver injury, including some fatalities, have been reported.

    Appropriate laboratory testing should be conducted prior to initiating and during therapy with PREZCOBIX®. Evidence of new or worsening liver dysfunction in patients on PREZCOBIX® should prompt consideration of interruption or discontinuation of treatment.

  • Severe Skin Reactions: Severe skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash with eosinophilia and systemic symptoms, and acute generalized exanthematous pustulosis have been reported in patients receiving darunavir coadministered with ritonavir. Mild-to-moderate rash was also reported and often occurred and resolved with continued dosing. Discontinue PREZCOBIX® immediately if signs or symptoms of severe skin reaction develop.

  • Sulfa Allergy:  Monitor patients with a known sulfonamide allergy after initiating PREZCOBIX®.

  • Effects on Serum Creatinine: Cobicistat decreases estimated creatinine clearance (CrCl) due to inhibition of tubular secretion of creatinine without affecting actual renal glomerular function. Prior to starting PREZCOBIX®, assess estimated CrCl. Patients who experience a confirmed increase in serum creatinine of greater than 0.4 mg/dL from baseline should be closely monitored for renal safety. Consider alternative medications that do not require dosage adjustments in patients with renal impairment.

  • Renal Impairment When Used With Tenofovir Disoproxil Fumarate: Renal impairment, including cases of acute renal failure and Fanconi syndrome, has been reported with the use of tenofovir DF and cobicistat. Coadministration with tenofovir DF is not recommended in patients who have an estimated CrCl <70 mL/min. In all patients, monitor estimated CrCl, urine glucose, and urine protein prior to initiating and during therapy. Measure serum phosphorus in patients at risk of renal impairment. Coadministration of PREZCOBIX® and tenofovir DF in combination with concomitant or recent use of a nephrotoxic agent is not recommended.

  • Risk of Serious Adverse Reactions or Loss of Virologic Response Due to Drug Interactions: PREZCOBIX® is a CYP3A inhibitor. Initiation of medications that inhibit or induce CYP3A may increase or decrease concentrations of PREZCOBIX® or the concomitant medications. This may lead to clinically significant adverse reactions (potentially leading to severe, life threatening, or fatal events) from higher exposures of the concomitant medications or adverse reactions from higher exposures of PREZCOBIX®. Decreased concentrations of PREZCOBIX® may result in loss of therapeutic effect and possible development of resistance.

  • Antiretrovirals Not Recommended:  Do not use PREZCOBIX® in combination with other antiretroviral drugs that require pharmacokinetic boosting or which contain the individual components of PREZCOBIX® (darunavir and cobicistat) or with ritonavir.

  • Diabetes Mellitus/Hyperglycemia and Hemophilia: New onset or exacerbation of pre-existing diabetes mellitus and hyperglycemia have been reported in patients receiving protease inhibitors. Initiation or dose adjustments of insulin or oral hypoglycemic agents may be required. Increased bleeding in hemophiliacs has been reported in patients receiving protease inhibitors.

  • Fat Redistribution: Redistribution and/or accumulation of body fat have been observed in patients receiving antiretroviral therapy.

  • Immune Reconstitution Syndrome including the occurrence of autoimmune disorders with variable time to onset has been reported.

Adverse Reactions

  • The most common clinical adverse reactions (incidence ≥5%) of at least moderate intensity (≥Grade 2) were diarrhea, nausea, rash, headache, abdominal pain, and vomiting during the darunavir clinical development program, where darunavir was coadministered with ritonavir.

This is not a complete list of all adverse drug reactions reported with the use of PREZCOBIX®. Please refer to the full Prescribing Information for a complete list of adverse drug reactions.
