Duration of therapy should be determined by the clinical response (see section 5.1).
For long-term treatment beyond 6 months, the benefit-risk balance should be carefully considered (seesections 5.1 and 5.3).
Switch to oral isavuconazole
CRESEMBA is available as 100 mg and 40 mg hard capsules. On the basis of the high oralbioavailability (98%, see section 5.2), switching between intravenous and oral administration isappropriate when clinically indicated. For detailed dosing recommendations, please see section 4.2 ofthe Summary of Product Characteristics for CRESEMBA 40 mg and 100 mg hard capsules.
ElderlyNo dose adjustment is necessary for elderly patients; however, the clinical experience in elderlypatients is limited.
Renal impairmentNo dose adjustment is necessary in adult patients with renal impairment, including patients with end-stage renal disease (see section 5.2).
No dose recommendation can be made for paediatric patients with renal impairment, as no relevantdata are available.
Hepatic impairmentNo dose adjustment is necessary in adult patients with mild or moderate hepatic impairment (Child-
Pugh Classes A and B) (see sections 4.4 and 5.2).
Isavuconazole has not been studied in adult patients with severe hepatic impairment (Child-Pugh Class
C). Use in these patients is not recommended unless the potential benefit is considered to outweigh therisks (see sections 4.4, pct. 4.8 and 5.2).
No dose recommendation can be made for paediatric patients with hepatic impairment, as no relevantdata are available.
Paediatric populationThe safety and efficacy of isavuconazole in paediatric patients aged less than 1 year has not beenestablished.
Method of administrationIntravenous use.Precautions to be taken before handling or administering the medicinal productCRESEMBA must be reconstituted and then further diluted to a concentration corresponding to arange of 0.4 to 0.8 mg/mL isavuconazole prior to administration by intravenous infusion over aminimum of 1 hour to reduce the risk of infusion-related reactions. Higher concentrations should beavoided as these may cause local irritation at the site of infusion. The infusion must be administeredvia an infusion set with an in-line filter with a microporous membrane made of polyethersulfone (PES)and with a pore size of 0.2 μm to 1.2 μm. CRESEMBA must only be given as an intravenous infusion.
For detailed instructions on the reconstitution and dilution of CRESEMBA before administration, seesection 6.6.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Co-administration with ketoconazole (see section 4.5).
Co-administration with high-dose ritonavir (>200 mg every 12 hours) (see section 4.5).
Co-administration with strong CYP3A4/5 inducers such as rifampicin, rifabutin, carbamazepine, long-acting barbiturates (e.g. phenobarbital), phenytoin and St. John’s wort or with moderate CYP3A4/5inducers such as efavirenz, nafcillin and etravirine (see section 4.5).
Patients with familial short QT syndrome (see section 4.4).
4.4 Special warnings and precautions for use
HypersensitivityHypersensitivity to isavuconazole may result in adverse reactions that include: anaphylactic reaction,hypotension, respiratory failure, dyspnoea, drug eruption, pruritus, and rash (see section 4.8). In caseof anaphylactic reaction, isavuconazole should be discontinued immediately and appropriate medicaltreatment should be initiated.
Caution should be used in prescribing isavuconazole to patients with hypersensitivity to other azoleantifungal agents.
Infusion-related reactionsDuring intravenous administration of isavuconazole, infusion-related reactions including hypotension,dyspnoea, dizziness, paraesthesia, nausea, and headache were reported (see section 4.8). The infusionshould be stopped if these reactions occur.
Severe cutaneous adverse reactionsSevere cutaneous adverse reactions, such as Stevens-Johnson syndrome, have been reported duringtreatment with azole antifungal agents. If a patient develops a severe cutaneous adverse reaction,
CRESEMBA should be discontinued.
CardiovascularQT shortening
Isavuconazole is contraindicated in patients with familial short QT syndrome (see section 4.3).
In a QT study in healthy human subjects, isavuconazole shortened the QTc interval in aconcentration-related manner. For the 200 mg dosing regimen, the least squares mean (LSM)difference from placebo was 13.1 ms at 2 hours post dose [90% CI: 17.1, 9.1 ms]. Increasing the doseto 600 mg resulted in an LSM difference from placebo of 24.6 ms at 2 hours post dose [90% CI: 28.7,20.4 ms].
Caution is warranted when prescribing isavuconazole to patients taking other medicinal productsknown to decrease the QT interval, such as rufinamide.
Elevated liver transaminases or hepatitis
Elevated liver transaminases have been reported in clinical studies (see section 4.8). The elevations inliver transaminases rarely required discontinuation of isavuconazole. Monitoring of hepatic enzymesshould be considered, as clinically indicated. Hepatitis has been reported with azole antifungal agentsincluding isavuconazole.
Severe hepatic impairmentIsavuconazole has not been studied in patients with severe hepatic impairment (Child-Pugh Class C).
Use in these patients is not recommended unless the potential benefit is considered to outweigh therisks. These patients should be carefully monitored for potential drug toxicity (see sections 4.2, pct. 4.8and 5.2).
Concomitant use with other medicinal productsCYP3A4/5 inhibitors
Ketoconazole is contraindicated (see section 4.3). For the strong CYP3A4 inhibitor lopinavir/ritonavir,a two-fold increase in isavuconazole exposure was observed. For other strong CYP3A4/5 inhibitors, aless pronounced effect can be expected. No dose adjustment of isavuconazole is necessary when co-administered with strong CYP3A4/5 inhibitors, however caution is advised as adverse drug reactionsmay increase (see section 4.5).
CYP3A4/5 inducers
Co-administration with mild CYP3A4/5 inducers such as aprepitant, prednisone, and pioglitazone,may result in mild to moderate decreases of isavuconazole plasma levels; co-administration with mild
CYP3A4/5 inducers should be avoided unless the potential benefit is considered to outweigh the risk(see section 4.5).
CYP3A4/5 substrates including immunosuppressants
Isavuconazole can be considered a moderate inhibitor of CYP3A4/5, and systemic exposure tomedicinal products metabolised by CYP3A4 may be increased when co-administered withisavuconazole. Concomitant use of isavuconazole with CYP3A4 substrates such as theimmunosuppressants tacrolimus, sirolimus or ciclosporin may increase the systemic exposure to thesemedicinal products. Appropriate therapeutic drug monitoring and dose adjustment may be necessaryduring co-administration (see section 4.5).
CYP2B6 substratesIsavuconazole is an inducer of CYP2B6. Systemic exposure to medicinal products metabolised by
CYP2B6 may be decreased when co-administered with isavuconazole. Therefore, caution is advisedwhen CYP2B6 substrates, especially medicinal products with a narrow therapeutic index such ascyclophosphamide, are co-administered with isavuconazole. The use of the CYP2B6 substrateefavirenz with isavuconazole is contraindicated because efavirenz is a moderate inducer of CYP3A4/5(see section 4.3).
P-gp substratesIsavuconazole may increase the exposure of medicinal products that are P-gp substrates. Doseadjustment of medicinal products that are P-gp substrates, especially medicinal products with a narrowtherapeutic index such as digoxin, colchicine and dabigatran etexilate, may be needed whenconcomitantly administered with isavuconazole (see section 4.5).
Limitations of the clinical data
The clinical data for isavuconazole in the treatment of mucormycosis are limited to one prospectivenon-controlled clinical study in 37 adult patients with proven or probable mucormycosis who receivedisavuconazole for primary treatment, or because other antifungal treatments (predominantlyamphotericin B) were inappropriate.
For individual Mucorales species, the clinical efficacy data are very limited, often to one or twopatients (see section 5.1). Susceptibility data were available in only a small subset of cases. These dataindicate that concentrations of isavuconazole required for inhibition in vitro are very variable betweengenera/species within the order of Mucorales, and generally higher than concentrations required toinhibit Aspergillus species. It should be noted that there was no dose-finding study in mucormycosis,and patients were administered the same dose of isavuconazole as was used for the treatment ofinvasive aspergillosis.
4.5 Interaction with other medicinal products and other forms of interaction
Potential of medicinal products to affect the pharmacokinetics of isavuconazole
Isavuconazole is a substrate of CYP3A4 and CYP3A5 (see section 5.2). Co-administration ofmedicinal products which are inhibitors of CYP3A4 and/or CYP3A5 may increase the plasmaconcentrations of isavuconazole. Co-administration of medicinal products which are inducers of
CYP3A4 and/or CYP3A5 may decrease the plasma concentrations of isavuconazole.
Medicinal products that inhibit CYP3A4/5
Co-administration of isavuconazole with the strong CYP3A4/5 inhibitor ketoconazole iscontraindicated, since this medicinal product can significantly increase plasma concentrations ofisavuconazole (see sections 4.3 and 4.5).
For the strong CYP3A4 inhibitor lopinavir/ritonavir, a two-fold increase in isavuconazole exposurewas observed. For other strong CYP3A4 inhibitors, such as clarithromycin, indinavir and saquinavir, aless pronounced effect can be expected, based on their relative potency. No dose adjustment ofisavuconazole is necessary when co-administered with strong CYP3A4/5 inhibitors, however cautionis advised as adverse drug reactions may increase (see section 4.4).
No dose adjustment is warranted for moderate to mild CYP3A4/5 inhibitors.
Medicinal products that induce CYP3A4/5
Co-administration of isavuconazole with potent CYP3A4/5 inducers such as rifampicin, rifabutin,carbamazepine, long-acting barbiturates (e.g., phenobarbital), phenytoin and St. John’s wort, or withmoderate CYP3A4/5 inducers such as efavirenz, nafcillin and etravirine, is contraindicated, sincethese medicinal products can significantly decrease plasma concentrations of isavuconazole (seesection 4.3).
Co-administration with mild CYP3A4/5 inducers such as aprepitant, prednisone and pioglitazone, mayresult in mild to moderate decreases of isavuconazole plasma levels; co-administration with mild
CYP3A4/5 inducers should be avoided unless the potential benefit is considered to outweigh the risk(see section 4.4).
Co-administration with high-dose ritonavir (>200 mg twice daily) is contraindicated, as at high dosesritonavir may induce CYP3A4/5 and decrease isavuconazole plasma concentrations (see section 4.3).
Potential for isavuconazole to affect exposures of other medicines
Medicinal products metabolised by CYP3A4/5
Isavuconazole is a moderate inhibitor of CYP3A4/5; co-administration of isavuconazole withmedicinal products which are substrates of CYP3A4/5 may result in increased plasma concentrationsof these medicinal products.
Medicinal products metabolised by CYP2B6
Isavuconazole is a mild CYP2B6 inducer; co-administration of isavuconazole may result in decreasedplasma concentrations of CYP2B6 substrates.
Medicinal products transported by P-gp in the intestine
Isavuconazole is a mild inhibitor of P-glycoprotein (P-gp); co-administration with isavuconazole mayresult in increased plasma concentrations of P-gp substrates.
Medicinal products transported by BCRP
Isavuconazole is an inhibitor in vitro of BCRP, and plasma concentrations of substrates of BCRP maytherefore be increased. Caution is advised when isavuconazole is given concomitantly with substratesof BCRP.
Medicinal products renally excreted via transport proteins
Isavuconazole is a mild inhibitor of the organic cation transporter 2 (OCT2). Co-administration ofisavuconazole with medicinal products which are substrates of OCT2 may result in increased plasmaconcentrations of these medicinal products.
Uridine diphosphate-glucuronosyltransferases (UGT) substrates
Isavuconazole is a mild inhibitor of UGT. Co-administration of isavuconazole with medicinal productswhich are substrates of UGT may result in mildly increased plasma concentrations of these medicinalproducts.
Interaction tableInteractions between isavuconazole and co-administered medicinal products are listed in Table 2(increase is indicated as “↑”, decrease as “↓”), ordered by therapeutic class. Unless otherwise stated,studies detailed in Table 2 have been performed in adults with the recommended dose ofisavuconazole.

4.6 Fertility, pregnancy and lactation
PregnancyThere are no data from the use of CRESEMBA in pregnant women.
Studies in animals have shown reproductive toxicity (see section 5.3). The potential risk for humans isunknown.
CRESEMBA must not be used during pregnancy except in patients with severe or potentially life-threatening fungal infections, in whom isavuconazole may be used if the anticipated benefits outweighthe possible risks to the foetus.
Women of child-bearing potentialCRESEMBA is not recommended for women of childbearing potential who are not usingcontraception.
Breast-feedingAvailable pharmacodynamic/toxicological data in animals have shown excretion ofisavuconazole/metabolites in milk (see section 5.3).
A risk to newborns and infants cannot be excluded.
Breast-feeding should be discontinued during treatment with CRESEMBA.
FertilityThere are no data on the effect of isavuconazole on human fertility. Studies in animals did not showimpairment of fertility in male or female rats (see section 5.3).
4.7 Effects on ability to drive and use machines
Isavuconazole has a moderate potential to influence the ability to drive and use machines. Patientsshould avoid driving or operating machinery if symptoms of confusional state, somnolence, syncope,and/or dizziness are experienced.

Laboratory effects
In a double-blind, randomized, active-controlled clinical study of 516 patients with invasive fungaldisease caused by Aspergillus species or other filamentous fungi, elevated liver transaminases (alanineaminotransferase or aspartate aminotransferase) > 3 × Upper Limit of Normal (ULN) were reported atthe end of study treatment in 4.4% of patients who received isavuconazole. Marked elevations of livertransaminases > 10 × ULN developed in 1.2% of patients on isavuconazole.
Paediatric populationThe clinical safety of isavuconazole was assessed in 77 paediatric patients who received at least onedose of intravenous or oral isavuconazole. This included 46 paediatric patients who receivedisavuconazole as a single dose and who also received other antifungals for prophylaxis, and 31patients with suspected or confirmed invasive aspergillosis or mucormycosis who receivedisavuconazole as primary therapy for up to 181 days. Overall, the safety profile of isavuconazole in thepaediatric population was similar to that in adults.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
4.9 Overdose
SymptomsSymptoms reported more frequently at supratherapeutic doses of isavuconazole (equivalent toisavuconazole 600 mg/day) evaluated in a QT study than in the therapeutic dose group (equivalent toisavuconazole 200 mg/day dose) included: headache, dizziness, paraesthesia, somnolence, disturbancein attention, dysgeusia, dry mouth, diarrhoea, oral hypoaesthesia, vomiting, hot flush, anxiety,restlessness, palpitations, tachycardia, photophobia and arthralgia.
Management of overdoseIsavuconazole is not removed by haemodialysis. There is no specific antidote for isavuconazole. In theevent of an overdose, supportive treatment should be instituted.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antimycotics for systemic use, triazole- and tetrazole derivative, ATCcode: J02AC05.
Mechanism of actionIsavuconazole is the active moiety formed after oral or intravenous administration of isavuconazoniumsulfate (see section 5.2).
Isavuconazole demonstrates a fungicidal effect by blocking the synthesis of ergosterol, a keycomponent of the fungal cell membrane, through the inhibition of cytochrome P-450-dependentenzyme lanosterol 14-alpha-demethylase, responsible for the conversion of lanosterol to ergosterol.
This results in an accumulation of methylated sterol precursors and a depletion of ergosterol within thecell membrane, thus weakening the structure and function of the fungal cell membrane.
MicrobiologyIn animal models of disseminated and pulmonary aspergillosis, the pharmacodynamic (PD) indeximportant in efficacy is exposure divided by minimum inhibitory concentration (MIC) (AUC/MIC).
No clear correlation between in vitro MIC and clinical response for the different species (Aspergillusand Mucorales) could be established.
Concentrations of isavuconazole required to inhibit Aspergillus species and genera/species of the order
Mucorales in vitro have been very variable. Generally, concentrations of isavuconazole required toinhibit Mucorales are higher than those required to inhibit the majority of Aspergillus species.
Clinical efficacy has been demonstrated for the following Aspergillus species: Aspergillus fumigatus,
A. flavus, A. niger, and A. terreus (see further below).
Mechanism(s) of resistance
Reduced susceptibility to triazole antifungal agents has been associated with mutations in the fungalcyp51A and cyp51B genes coding for the target protein lanosterol 14-alpha-demethylase involved inergosterol biosynthesis. Fungal strains with reduced in vitro susceptibility to isavuconazole have beenreported, and cross-resistance with voriconazole and other triazole antifungal agents cannot beexcluded.

Clinical efficacy and safetyTreatment of invasive aspergillosis
The safety and efficacy of isavuconazole for the treatment of adult patients with invasive aspergillosiswas evaluated in a double-blind, active-controlled clinical study in 516 patients with invasive fungaldisease caused by Aspergillus species or other filamentous fungi. In the intent-to-treat (ITT)population, 258 patients received isavuconazole and 258 patients received voriconazole.
Isavuconazole was administered intravenously (equivalent to 200 mg isavuconazole) every 8 hours forthe first 48 hours, followed by once-daily intravenous or oral treatment (equivalent to 200 mgisavuconazole). The protocol-defined maximum treatment duration was 84 days. Median treatmentduration was 45 days.
The overall response at end-of-treatment (EOT) in the myITT population (patients with proven andprobable invasive aspergillosis based on cytology, histology, culture or galactomannan testing) wasassessed by an independent blinded Data Review Committee. The myITT population comprised 123patients receiving isavuconazole and 108 patients receiving voriconazole. The overall response in thispopulation was n = 43 (35%) for isavuconazole and n = 42 (38.9%) for voriconazole. The adjustedtreatment difference (voriconazole−isavuconazole) was 4.0% (95% confidence interval: −7.9; 15.9).
The all-cause mortality at Day 42 in this population was 18.7% for isavuconazole and 22.2% forvoriconazole. The adjusted treatment difference (isavuconazole−voriconazole) was −2.7% (95 %confidence interval: −12.9; 7.5).
Treatment of mucormycosis
In an open-label non-controlled study, 37 adult patients with proven or probable mucormycosisreceived isavuconazole at the same dose regimen as that used to treat invasive aspergillosis. Mediantreatment duration was 84 days for the overall mucormycosis patient population, and 102 days for the21 patients not previously treated for mucormycosis. For patients with probable or provenmucormycosis as defined by the independent Data Review Committee (DRC), all-cause mortality at
Day 84 was 43.2% (16/37) for the overall patient population, 42.9% (9/21) for mucormycosis patientsreceiving isavuconazole as primary treatment, and 43.8% (7/16) for mucormycosis patients receivingisavuconazole who were refractory to, or intolerant of, prior antifungal therapy (mainly amphotericin
B-based treatments). The DRC-assessed overall success rate at EOT was 11/35 (31.4%), with 5patients considered completely cured and 6 patients partially cured. A stable response was observed inan additional 10/35 patients (28.6%). In 9 patients with mucormycosis due to Rhizopus spp., 4 patientsshowed a favourable response to isavuconazole. In 5 patients with mucormycosis due to Rhizomucorspp., no favourable responses were observed. The clinical experience in other species is very limited(Lichtheimia spp. n=2, Cunninghamella spp. n=1, Actinomucor elegans n=1).
Paediatric populationThe clinical safety of isavuconazole was assessed in 77 paediatric patients who received at least onedose of intravenous or oral isavuconazole, including 31 paediatric patients who receivedisavuconazole in a clinical study for treating invasive aspergillosis or mucormycosis. Isavuconazolewas safe and well tolerated in the treatment of invasive aspergillosis and mucormycosis at the intendedtreatment durations.
5.2 Pharmacokinetic properties
Isavuconazonium sulfate is a water-soluble prodrug that can be administered as an intravenousinfusion or orally as hard capsules. Following administration, isavuconazonium sulfate is rapidlyhydrolysed by plasma esterases to the active moiety isavuconazole; plasma concentrations of theprodrug are very low, and detectable only for a short time after intravenous dosing.
AbsorptionFollowing oral administration of CRESEMBA in healthy adult subjects, the active moietyisavuconazole is absorbed and reaches maximum plasma concentrations (Cmax) approximately 2-3hours after single and multiple dosing (see Table 5).

Effect of food on absorption
Oral administration of CRESEMBA equivalent to 400 mg isavuconazole with a high-fat meal reducedisavuconazole Cmax by 9% and increased AUC by 9%. CRESEMBA can be taken with or withoutfood.
DistributionIsavuconazole is extensively distributed, with a mean steady state volume of distribution (Vss) ofapproximately 450 L. Isavuconazole is highly bound (> 99%) to human plasma proteins,predominantly to albumin.
BiotransformationIn vitro/in vivo studies indicate that CYP3A4, CYP3A5, and subsequently uridine diphosphate-glucuronosyltransferases (UGT), are involved in the metabolism of isavuconazole.
Following single doses of [cyano-14C] isavuconazonium and [pyridinylmethyl-14C] isavuconazoniumsulfate in humans, in addition to the active moiety (isavuconazole) and the inactive cleavage product, anumber of minor metabolites were identified. Except for the active moiety isavuconazole, noindividual metabolite was observed with an AUC > 10% of total radio-labelled material.
EliminationFollowing oral administration of radio-labelled isavuconazonium sulfate to healthy subjects, a mean of46.1% of the radioactive dose was recovered in faeces, and 45.5% was recovered in urine.
Renal excretion of intact isavuconazole was less than 1% of the dose administered.
The inactive cleavage product is primarily eliminated by metabolism and subsequent renal excretionof the metabolites.
Linearity/non-linearityStudies in healthy subjects have demonstrated that the pharmacokinetics of isavuconazole areproportional up to 600 mg per day.
Pharmacokinetics in special populationsPaediatric patientsThe paediatric dosage regimens were confirmed using a population pharmacokinetic (popPK) modeldeveloped using data from three clinical studies (N = 97); this included two clinical studies (N = 73)conducted in paediatric patients aged 1 to < 18 years, of whom 31 received isavuconazole for treatinginvasive aspergillosis or mucormycosis.
The predicted exposures to isavuconazole for paediatric patients at steady state based on different agegroups, weight, route of administration, and dose are shown in Table 7.

The predicted exposures for paediatric patients, regardless of route of administration and age group,were comparable to exposures at steady state (AUCss) from a clinical study conducted in adultpatients with infections caused by Aspergillus species and other filamentous fungi (mean AUCss =101.2 h*mg/L with standard deviation (SD) = 55.9, see Table 7).
The predicted exposures under the paediatric dosing regimen were lower than the exposures of adultswho received multiple daily supratherapeutic doses of 600 mg isavuconazole (Table 5), where therewas a greater occurrence of adverse events (see section 4.9).
Renal impairmentNo clinically relevant changes were observed in the total Cmax and AUC of isavuconazole in adultsubjects with mild, moderate or severe renal impairment compared to subjects with normal renalfunction. Of the 403 patients who received isavuconazole in the Phase 3 studies, 79 (20%) of patientshad an estimated glomerular filtration rate (GFR) less than 60 mL/min/1.73 m2. No dose adjustment isrequired in patients with renal impairment, including those patients with end-stage renal disease.
Isavuconazole is not readily dialysable (see section 4.2).
No data are available in paediatric patients with renal impairment (see section 4.2).
Hepatic impairmentAfter a single 100 mg dose of isavuconazole was administered to 32 adult patients with mild (Child-
Pugh Class A) hepatic insufficiency and 32 patients with moderate (Child-Pugh Class B) hepaticinsufficiency (16 intravenous and 16 oral patients per Child-Pugh class), the least square meansystemic exposure (AUC) increased 64% in the Child-Pugh Class A group, and 84% in the Child-Pugh
Class B group, relative to 32 age- and weight-matched healthy subjects with normal hepatic function.
Mean plasma concentrations (Cmax) were 2% lower in the Child-Pugh Class A group and 30% lower inthe Child-Pugh Class B group. The population pharmacokinetic evaluation of isavuconazole in healthysubjects and patients with mild or moderate hepatic dysfunction demonstrated that the mild andmoderate hepatic impairment populations had 40% and 48% lower isavuconazole clearance (CL)values, respectively, than the healthy population.
No dose adjustment is required in adult patients with mild to moderate hepatic impairment.
Isavuconazole has not been studied in adult patients with severe hepatic impairment (Child-Pugh Class
C). Use in these patients is not recommended unless the potential benefit is considered to outweigh therisks (see sections 4.2 and 4.4).
No data are available in paediatric patients with hepatic impairment (see section 4.2).
5.3 Preclinical safety data
In rats and rabbits, isavuconazole at systemic exposures below the therapeutic level were associatedwith dose-related increases in the incidence of skeletal anomalies (rudimentary supernumerary ribs) inoffspring. In rats, a dose-related increase in the incidence of zygomatic arch fusion was also noted inoffspring (see section 4.6).
Administration of isavuconazonium sulfate to rats at a dose of 90 mg/kg/day (approximately 1.0-foldthe systemic exposure at the human clinical maintenance dose of 200 mg isavuconazole) duringpregnancy through the weaning period showed an increased perinatal mortality of the pups. In uteroexposure to the active moiety isavuconazole had no effect on the fertility or the normal developmentof the surviving pups.
Intravenous administration of 14C-labelled isavuconazonium sulfate to lactating rats resulted in therecovery of radiolabel in the milk.
Isavuconazole did not affect the fertility of male or female rats treated with oral doses up to90 mg/kg/day (approximately 1.0-fold the systemic exposure at the human clinical maintenance doseof 200 mg isavuconazole).
Isavuconazole has no discernible mutagenic or genotoxic potential. Isavuconazole was negative in abacterial reverse mutation assay, was weakly clastogenic at cytotoxic concentrations in the
L5178Y tk+/- mouse lymphoma chromosome aberration assay, and showed no biologically relevant orstatistically significant increase in the frequency of micronuclei in an in vivo rat micronucleus test.
Isavuconazole has demonstrated carcinogenic potential in 2-year rodent carcinogenicity studies. Liverand thyroid tumours are likely caused by a rodent-specific mechanism that is not relevant for humans.
Skin fibromas and fibrosarcomas were seen in male rats. The mechanism underlying this effect isunknown. Endometrial adenomas and carcinomas of the uterus were seen in female rats, which islikely due to a hormonal disturbance. There is no safety margin for these effects. The relevance forhumans of the skin and uterine tumours cannot be excluded.
Isavuconazole inhibited the hERG potassium channel and the L-type calcium channel with an IC50 of5.82 µM and 6.57 µM respectively (34- and 38-fold the human non-protein bound Cmax at maximumrecommended human dose [MRHD], respectively). The in vivo 39-week repeated-dose toxicologystudies in monkeys did not show QTcF prolongation at doses up to 40 mg/kg/day (approximately1.0-fold the systemic exposure at the human clinical maintenance dose of 200 mg isavuconazole).
Juvenile animal studiesIsavuconazonium sulfate, when administered to juvenile rats, demonstrated a similar toxicologicalprofile to that observed in adult animals. In juvenile rats, treatment-related toxicity considered rodentspecific was observed in the liver and thyroid. These changes are not considered clinically relevant.
Based on the no-observed-adverse-effect level in juvenile rats, the safety margins forisavuconazonium sulfate were approximately 0.2- to 0.5-fold the systemic exposure at the clinicalmaintenance dose for paediatric patients, similar to those observed in adult rats.
Environmental risk assessment (ERA)Environmental risk assessment has shown that isavuconazole may pose a risk for the aquaticenvironment.

6.6 Special precautions for disposal and other handling
ReconstitutionOne vial of the powder for concentrate for solution for infusion should be reconstituted by addition of5 mL water for injections to the vial. The reconstituted concentrate contains 40 mg isavuconazole permL. The vial should be shaken to dissolve the powder completely. The reconstituted solution shouldbe inspected visually for particulate matter and discoloration. Reconstituted concentrate should beclear and free of visible particulate. It must be further diluted prior to administration.
DilutionAdults and paediatric patients with bodyweight from 37 kg:
After reconstitution, the entire content of the reconstituted concentrate should be removed from thevial and added to an infusion bag containing 250 mL of either sodium chloride 9 mg/mL (0.9%)solution for injection or 50 mg/mL (5%) dextrose solution. The infusion solution containsapproximately 0.8 mg isavuconazole per mL.
Paediatric patients with bodyweight below 37 kg:
The final concentration of the infusion solution should be in the range of 0.4 to 0.8 mg isavuconazoleper mL. Higher concentrations should be avoided as these may cause local irritation at the site ofinfusion.
To obtain the final concentration, the appropriate volume of the reconstituted concentrate based onpaediatric dosing recommendations (see section 4.2) should be removed from the vial and added to aninfusion bag containing the appropriate amount of diluent.
The appropriate volume of the infusion bag is calculated as follows:
[Required dose (mg)/final concentration (mg/mL)] - Volume of the concentrate (mL)
The concentrate can be diluted with either 9 mg/mL (0.9%) sodium chloride solution for injection or50 mg/mL (5%) dextrose solution.
AdministrationAfter the reconstituted concentrate is further diluted, the diluted solution may show fine white-to-translucent particulates of isavuconazole that do not sediment (but will be removed by in-linefiltration). The diluted solution should be mixed gently, or the bag should be rolled to minimise theformation of particulates. Unnecessary vibration or vigorous shaking of the solution should beavoided. The solution for infusion must be administered via an infusion set with an in-line filter (poresize 0.2 μm to 1.2 μm) made of polyether sulfone (PES). Infusion pumps can be used and must beplaced before the infusion set. Regardless of the infusion solution container size used, the entirevolume of the container should be administered to ensure the complete dose is administered.
Isavuconazole should not be infused into the same line or cannula concomitantly with otherintravenous products.
