  • Adult Patients: The most frequent adverse reactions in adult patients were nausea, vomiting, diarrhea, headache, elevated liver chemistry tests, hypokalemia, constipation, dyspnea, cough, peripheral edema, and back pain. ( 6.1 )
  • Pediatric Patients: The most frequent adverse reactions in pediatric patients were diarrhea, abdominal pain, vomiting, elevated liver chemistry tests, rash, nausea, pruritus, and headache. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Astellas Pharma US, Inc. at 1-800-727-7003 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of CRESEMBA cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trials Experience in Adult Patients A total of 403 adult patients were exposed to CRESEMBA in two clinical trials. The most frequently reported adverse reactions among CRESEMBA-treated patients were nausea (26%), vomiting (25%), diarrhea (22%), headache (17%), elevated liver chemistry tests (16%), hypokalemia (14%), constipation (13%), dyspnea (12%), cough (12%), peripheral edema (11%), and back pain (10%). Serious adverse reactions occurred in 223/403 (55%) of patients and 56/403 (14%) of patients permanently discontinued treatment with CRESEMBA due to an adverse reaction in the two trials. The adverse reactions which most often led to permanent discontinuation of CRESEMBA therapy during the clinical trials were confusional state (0.7%), acute renal failure (0.7%), increased blood bilirubin (0.5%), convulsion (0.5%), dyspnea (0.5%), epilepsy (0.5%), respiratory failure (0.5%), and vomiting (0.5%). Patients in the clinical trials were immunocompromised with underlying conditions including hematological malignancy, neutropenia post-chemotherapy, graft-versus-host disease, and hematopoietic stem cell transplant. The patient population was 61% male, had a mean age of 51 years (range 17-92, including 85 patients aged greater than 65 years), and was 79% White and 3% Black. One hundred forty-four (144) patients had a duration of CRESEMBA therapy of greater than 12 weeks, with 52 patients receiving CRESEMBA for over six months. In Trial 1, a randomized, double-blind, active-controlled clinical trial for treatment of invasive aspergillosis, treatment‑emergent adverse reactions occurred in 247/257 (96%), and 255/259 (99%) patients in the CRESEMBA and voriconazole treatment groups, respectively. Adverse reactions resulting in permanent discontinuation were reported in 37 (14%) CRESEMBA-treated patients and 59 (23%) voriconazole-treated patients. Table 3 includes selected adverse reactions which were reported at an incidence of ≥ 5% during CRESEMBA therapy in Trial 1. In Trial 2, an open-label, non-comparative trial of CRESEMBA in patients with invasive aspergillosis and renal impairment or invasive mucormycosis, adverse reactions occurred in 139/146 (95%) of patients in the CRESEMBA treatment group. Adverse reactions resulting in permanent discontinuation were reported in 19 (13%) CRESEMBA‑treated patients. The frequencies and types of adverse reactions observed in CRESEMBA-treated patients were similar between Trial 1 and Trial 2. Table 3.

    • Drug Interactions

    7 DRUG INTERACTIONS Isavuconazole is a sensitive substrate of CYP3A4. CYP3A4 inhibitors or inducers may alter the plasma concentrations of isavuconazole. Isavuconazole is a moderate inhibitor of CYP3A4, and a mild inhibitor of P-glycoprotein (P-gp), and organic cation transporter 2 (OCT2). Drug interaction studies were conducted to investigate the effect of coadministered drugs on the pharmacokinetics of isavuconazole and the effect of isavuconazole on the pharmacokinetics of coadministered drugs [see Clinical Pharmacology ( 12.3 )] . Table 4. Drug(s) Affecting Pharmacokinetics of CRESEMBA Recommendation Comments Ketoconazole Contraindicate coadministration of all potent CYP3A4 inhibitors There is more than a 5-fold increase in exposure of isavuconazole upon coadministration with ketoconazole [see Clinical Pharmacology ( 12.3 )] . Lopinavir/ritonavir 400 mg of lopinavir in combination with 100 mg of ritonavir. Caution is advised when CRESEMBA is coadministered with lopinavir/ritonavir There is a 96% increase in exposure of isavuconazole when coadministered with lopinavir/ritonavir [see Clinical Pharmacology ( 12.3 )] . Rifampin Contraindicate coadministration of all potent CYP3A4 inducers There is a 97% decrease in exposure of isavuconazole upon coadministration with rifampin [see Clinical Pharmacology ( 12.3 )] . Table 5. The Effect of CRESEMBA on the Pharmacokinetics of Other Drugs Recommendation Comments Lopinavir/ritonavir 400 mg of lopinavir in combination with 100 mg of ritonavir. Use with Caution Concomitant administration of lopinavir/ritonavir and CRESEMBA resulted in decreased exposure of lopinavir and ritonavir that could possibly result in loss of antiviral efficacy [see Clinical Pharmacology ( 12.3 )] . Atorvastatin Use with Caution Caution should be used when atorvastatin is used with CRESEMBA due to a potential increase in atorvastatin exposure. Monitor patients for adverse reactions that are typical of atorvastatin [see Clinical Pharmacology ( 12.3 )] . Cyclosporine Use with Caution Concomitant administration of CRESEMBA and cyclosporine results in increase in cyclosporine exposure. Monitor drug concentrations of cyclosporine and adjust dose as needed [see Clinical Pharmacology ( 12.3 )] . Sirolimus Use with Caution Concomitant administration of CRESEMBA and sirolimus results in increase in sirolimus exposure. Monitor drug concentrations of sirolimus and adjust dose as needed [see Clinical Pharmacology ( 12.3 )] . Tacrolimus Use with Caution Concomitant administration of CRESEMBA and tacrolimus results in increase in tacrolimus exposure. Monitor drug concentrations of tacrolimus and adjust dose as needed [see Clinical Pharmacology ( 12.3 )] . Midazolam Use with Caution Concomitant administration of CRESEMBA and midazolam results in increase in midazolam exposure. Consider dose reduction of midazolam when isavuconazole is coadministered [see Clinical Pharmacology ( 12.3 )] . Bupropion Use with Caution Concomitant administration of...

    Contraindications

    4 CONTRAINDICATIONS

  • CRESEMBA is contraindicated in persons with known hypersensitivity to isavuconazole.
  • Coadministration of strong CYP3A4 inhibitors, such as ketoconazole or high-dose ritonavir (400 mg every 12 hours), with CRESEMBA is contraindicated because strong CYP3A4 inhibitors can significantly increase the plasma concentration of isavuconazole [see Drug Interactions ( 7 ) and Clinical Pharmacology ( 12.3 )] .
  • Coadministration of strong CYP3A4 inducers, such as rifampin, carbamazepine, St. John’s wort, or long acting barbiturates with CRESEMBA is contraindicated because strong CYP3A4 inducers can significantly decrease the plasma concentration of isavuconazole [see Drug Interactions ( 7 ) and Clinical Pharmacology ( 12.3 )] .
  • CRESEMBA shortened the QTc interval in a concentration-related manner. CRESEMBA is contraindicated in patients with familial short QT syndrome [see Clinical Pharmacology ( 12.2 )] .
  • Hypersensitivity to CRESEMBA. ( 4 )
  • Coadministration with strong CYP3A4 inhibitors, such as ketoconazole or high-dose ritonavir. ( 4 , 7 )
  • Coadministration with strong CYP3A4 inducers, such as rifampin, carbamazepine, St. John’s wort, or long acting barbiturates. ( 4 , 7 )
  • Use in patients with familial short QT syndrome. ( 4 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary Based on findings from animal studies, CRESEMBA may cause fetal harm when administered to a pregnant woman. There are no available human data on the use of CRESEMBA in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, perinatal mortality was increased in the offspring of pregnant rats dosed orally with isavuconazonium sulfate at approximately 0.5 times the clinical exposure during pregnancy through the weaning period. In animal studies when isavuconazonium chloride was administered by oral gavage to pregnant rats and rabbits during organogenesis at exposures corresponding to less than the human maintenance dose, increases in the incidences of multiple skeletal abnormalities, including rudimentary cervical ribs and fused zygomatic arches, were observed (see Data). Advise pregnant women of the potential risk to a fetus [see Warnings and Precautions ( 5.4 )] . The estimated background risk of major birth defects and miscarriage for the indicated populations are 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%, respectively. Data Animal Data Isavuconazonium chloride administration during organogenesis (gestational days 6-17 in rats and gestational days 6-18 in rabbits) was associated with dose-related increases in the incidences of rudimentary cervical ribs in rats and rabbits at 30 and 45 mg/kg, respectively, equivalent to about 0.2 and 0.1 times of the clinical exposure based on AUC comparisons. In rats, dose-related increases in the incidences of zygomatic arch fusion and supernumerary ribs/rudimentary supernumerary ribs were also noted at 30 mg/kg and above, equivalent to 0.2 times the human AUC. Skeletal abnormalities...

    Overdosage

    10 OVERDOSAGE During clinical studies, total daily CRESEMBA doses higher than the recommended dose regimen were associated with an increased rate of adverse reactions. At supratherapeutic doses (three times the recommended maintenance dose) evaluated in a thorough QT study, there were proportionally more treatment-emergent adverse reactions than in the therapeutic dose group (maintenance dose) for the following: headache, dizziness, paresthesia, somnolence, disturbance in attention, dysgeusia, dry mouth, diarrhea, oral hypoesthesia, vomiting, hot flush, anxiety, restlessness, palpitations, tachycardia, photophobia and arthralgia. Adverse reactions leading to discontinuation of study drug occurred in 7 of 39 (17.9%) subjects in the supratherapeutic dose group. Isavuconazole is not removed by hemodialysis. There is no specific antidote for isavuconazole. Treatment should be supportive with appropriate monitoring.
