Please refer to the Summary of Product Characteristics of Posaconazole AHCL oral suspension for usein oropharyngeal candidiasis.
4.2 Posology and method of administration
Treatment should be initiated by a physician experienced in the management of fungal infections or inthe supportive care of high-risk patients for which posaconazole is indicated as prophylaxis.
Non-interchangeability between Posaconazole Accord tablets and posaconazole oral suspension
The tablet is not to be used interchangeably with the oral suspension due to the differences betweenthese two formulations in frequency of dosing, administration with food and plasma drugconcentration achieved. Therefore, follow the specific dose recommendations for each formulation.
PosologyPosaconazole is also available as 40 mg/mL oral suspension and 300 mg concentrate for solution forinfusion. Posaconazole tablets generally provide higher plasma drug exposures than posaconazole oralsuspension under both fed and fasted conditions. Therefore, the tablets are preferred formulation tooptimise plasma concentrations.
Recommended dose in paediatric patients from 2 years of age weighing more than 40 kg and in adultsis shown in Table 1.
Table 1. Recommended dose in paediatric patients from 2 years of age weighing more than 40 kg andin adults according to indication
Indication Dose and duration of therapy(See section 5.2)
Treatment of invasive aspergillosis Loading dose of 300 mg (three 100 mg tablets or 300 mg(only for adults) concentrate for solution for infusion) twice a day on the firstday, then 300 mg (three 100 mg tablets or 300 mgconcentrate for solution for infusion) once a day thereafter.
Each tablet dose may be taken without regard to food intake.
Recommended total duration of therapy is 6-12 weeks.
Switching between intravenous and oral administration isappropriate when clinically indicated.
Refractory invasive fungal infections Loading dose of 300 mg (three 100 mg tablets) twice a day(IFI)/patients with IFI intolerant to 1st on the first day, then 300 mg (three 100 mg tablets) once aline therapy day thereafter. Each dose may be taken without regard tofood intake. Duration of therapy should be based on theseverity of the underlying disease, recovery fromimmunosuppression, and clinical response.
Prophylaxis of invasive fungal Loading dose of 300 mg (three 100 mg tablets) twice a dayinfections on the first day, then 300 mg (three 100 mg tablets) once aday thereafter. Each dose may be taken without regard tofood intake. Duration of therapy is based on recovery fromneutropenia or immunosuppression. For patients with acutemyelogenous leukaemia or myelodysplastic syndromes,prophylaxis with Posaconazole Accord should start severaldays before the anticipated onset of neutropenia and continuefor 7 days after the neutrophil count rises above 500 cells permm3.
Special populationsRenal impairmentAn effect of renal impairment on the pharmacokinetics of posaconazole is not expected and no doseadjustment is recommended (see section 5.2).
Hepatic impairmentLimited data on the effect of hepatic impairment (including Child-Pugh C classification of chronicliver disease) on the pharmacokinetics of posaconazole demonstrate an increase in plasma exposurecompared to subjects with normal hepatic function, but do not suggest that dose adjustment isnecessary (see sections 4.4 and 5.2). It is recommended to exercise caution due to the potential forhigher plasma exposure.
Paediatric populationThe safety and efficacy of posaconazole in children aged below 2 years have not been established. Noclinical data are available.
Method of administrationFor oral use.
Posaconazole Accord may be taken with or without food (see section 5.2). The tablets should beswallowed whole with water and should not be crushed, chewed, or broken.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Co-administration with ergot alkaloids (see section 4.5).
Co-administration with the CYP3A4 substrates terfenadine, astemizole, cisapride, pimozide,halofantrine or quinidine since this may result in increased plasma concentrations of these medicinalproducts, leading to QTc prolongation and rare occurrences of torsades de pointes (see sections 4.4and 4.5).
Co-administration with the HMG-CoA reductase inhibitors simvastatin, lovastatin and atorvastatin(see section 4.5).
Co-administration during the initiation and dose-titration phase of venetoclax in Chronic Lymphocytic
Leukaemia (CLL) patients (see sections 4.4 and 4.5).
4.4 Special warnings and precautions for use
HypersensitivityThere is no information regarding cross-sensitivity between posaconazole and other azole antifungalagents. Caution should be used when prescribing posaconazole to patients with hypersensitivity toother azoles.
Hepatic toxicityHepatic reactions (e.g. mild to moderate elevations in ALT, AST, alkaline phosphatase, total bilirubinand/or clinical hepatitis) have been reported during treatment with posaconazole. Elevated liverfunction tests were generally reversible on discontinuation of therapy and in some instances these testsnormalised without interruption of therapy. Rarely, more severe hepatic reactions with fatal outcomeshave been reported.
Posaconazole should be used with caution in patients with hepatic impairment due to limited clinicalexperience and the possibility that posaconazole plasma levels may be higher in these patients (seesections 4.2 and 5.2).
Monitoring of hepatic functionLiver function tests should be evaluated at the start of and during the course of posaconazole therapy.
Patients who develop abnormal liver function tests during posaconazole therapy must be routinelymonitored for the development of more severe hepatic injury. Patient management should includelaboratory evaluation of hepatic function (particularly liver function tests and bilirubin).
Discontinuation of posaconazole should be considered if clinical signs and symptoms are consistentwith development of liver disease.
QTc prolongation
Some azoles have been associated with prolongation of the QTc interval. Posaconazole must not beadministered with medicinal products that are substrates for CYP3A4 and are known to prolong the
QTc interval (see sections 4.3 and 4.5). Posaconazole should be administered with caution to patientswith pro-arrhythmic conditions such as:
- Congenital or acquired QTc prolongation
- Cardiomyopathy, especially in the presence of cardiac failure
- Sinus bradycardia
- Existing symptomatic arrhythmias
- Concomitant use with medicinal products known to prolong the QTc interval (other than thosementioned in section 4.3).
Electrolyte disturbances, especially those involving potassium, magnesium or calcium levels, shouldbe monitored and corrected as necessary before and during posaconazole therapy.
Drug interactionsPosaconazole is an inhibitor of CYP3A4 and should only be used under specific circumstances duringtreatment with other medicinal products that are metabolised by CYP3A4 (see section 4.5).
Midazolam and other benzodiazepines
Due to the risk of prolonged sedation and possible respiratory depression co-administration ofposaconazole with any benzodiazepines metabolised by CYP3A4 (e.g. midazolam, triazolam,alprazolam) should only be considered if clearly necessary. Dose adjustment of benzodiazepinesmetabolised by CYP3A4 should be considered (see section 4.5).
Vincristine toxicity
Concomitant administration of azole antifungals, including posaconazole, with vincristine has beenassociated with neurotoxicity and other serious adverse reactions, including seizures, peripheralneuropathy, syndrome of inappropriate antidiuretic hormone secretion, and paralytic ileus. Reserveazole antifungals, including posaconazole, for patients receiving a vinca alkaloid, includingvincristine, who have no alternative antifungal treatment options (see section 4.5).
Venetoclax toxicity
Concomitant administration of strong CYP3A inhibitors, including posaconazole, with the CYP3A4substrate venetoclax, may increase venetoclax toxicities, including the risk of tumour lysis syndrome(TLS) and neutropenia (see sections 4.3 and 4.5). Refer to the venetoclax SmPC for detailed guidance.
Rifamycin antibacterials (rifampicin, rifabutin), flucloxacillin, certain anticonvulsants (phenytoin,carbamazepine, phenobarbital, primidone), and efavirenz
Posaconazole concentrations may be significantly lowered in combination; therefore, concomitant usewith posaconazole should be avoided unless the benefit to the patient outweighs the risk (seesection 4.5).
Photosensitivity reaction
Posaconazole may cause increased risk of photosensitivity reaction. Patients should be advised toavoid sun exposure during treatment without adequate protection such as protective clothing andsunscreen with a high sun protection factor (SPF).
Plasma exposure
Posaconazole plasma concentrations following administration of posaconazole tablets are generallyhigher than those obtained with posaconazole oral suspension. Posaconazole plasma concentrationsfollowing administration of posaconazole tablets may increase over time in some patients (seesection 5.2).
Gastrointestinal dysfunction
There are limited pharmacokinetic data in patients with severe gastrointestinal dysfunction (such assevere diarrhoea). Patients who have severe diarrhoea or vomiting should be monitored closely forbreakthrough fungal infections.
ExcipientsThis medicinal product contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially‘sodium-free’.
4.5 Interaction with other medicinal products and other forms of interaction
Effects of other medicinal products on posaconazole
Posaconazole is metabolised via UDP glucuronidation (phase 2 enzymes) and is a substrate forp-glycoprotein (P-gp) efflux in vitro. Therefore, inhibitors (e.g. verapamil, ciclosporin, quinidine,clarithromycin, erythromycin, etc.) or inducers (e.g. rifampicin, rifabutin, certain anticonvulsants, etc.)of these clearance pathways may increase or decrease posaconazole plasma concentrations,respectively.
Flucloxacillin
Flucloxacillin (a CYP450 inducer) may decrease plasma posaconazole concentrations. Concomitantuse of posaconazole and flucloxacillin should be avoided unless the benefit to the patient outweighsthe risk (see section 4.4).
RifabutinRifabutin (300 mg once a day) decreased the Cmax (maximum plasma concentration) and AUC (areaunder the plasma concentration time curve) of posaconazole to 57 % and 51 %, respectively.
Concomitant use of posaconazole and rifabutin and similar inducers (e.g. rifampicin) should beavoided unless the benefit to the patient outweighs the risk. See also below regarding the effect ofposaconazole on rifabutin plasma levels.
EfavirenzEfavirenz (400 mg once a day) decreased the Cmax and AUC of posaconazole by 45 % and 50 %,respectively. Concomitant use of posaconazole and efavirenz should be avoided unless the benefit tothe patient outweighs the risk.
FosamprenavirCombining fosamprenavir with posaconazole may lead to decreased posaconazole plasmaconcentrations. If concomitant administration is required, close monitoring for breakthrough fungalinfections is recommended. Repeat dose administration of fosamprenavir (700 mg twice daily x10 days) decreased the Cmax and AUC of posaconazole oral suspension (200 mg once daily on the1st day, 200 mg twice daily on the 2nd day, then 400 mg twice daily x 8 Days) by 21 % and 23 %,respectively. The effect of posaconazole on fosamprenavir levels when fosamprenavir is given withritonavir is unknown.
PhenytoinPhenytoin (200 mg once a day) decreased the Cmax and AUC of posaconazole by 41 % and 50 %,respectively. Concomitant use of posaconazole and phenytoin and similar inducers (e.g.
carbamazepine, phenobarbital, primidone) should be avoided unless the benefit to the patientoutweighs the risk.
H2 receptor antagonists and proton pump inhibitors
No clinically relevant effects were observed when posaconazole tablets are concomitantly used withantacids, H2-receptor antagonists and proton pump inhibitors. No dose adjustment of posaconazoletablets is required when posaconazole tablets are concomitantly used with antacids, H2-receptorantagonists and proton pump inhibitors.
Effects of posaconazole on other medicinal products
Posaconazole is a potent inhibitor of CYP3A4. Co-administration of posaconazole with CYP3A4substrates may result in large increases in exposure to CYP3A4 substrates as exemplified by theeffects on tacrolimus, sirolimus, atazanavir and midazolam below. Caution is advised during co-administration of posaconazole with CYP3A4 substrates administered intravenously and the dose ofthe CYP3A4 substrate may need to be reduced. If posaconazole is used concomitantly with CYP3A4substrates that are administered orally, and for which an increase in plasma concentrations may beassociated with unacceptable adverse reactions, plasma concentrations of the CYP3A4 substrateand/or adverse reactions should be closely monitored and the dose adjusted as needed. Several of theinteraction studies were conducted in healthy volunteers in whom a higher exposure to posaconazoleoccurs compared to patients administered the same dose. The effect of posaconazole on CYP3A4substrates in patients might be somewhat lower than that observed in healthy volunteers, and isexpected to be variable between patients due to the variable posaconazole exposure in patients. Theeffect of co-administration with posaconazole on plasma levels of CYP3A4 substrates may also bevariable within a patient.
Terfenadine, astemizole, cisapride, pimozide, halofantrine and quinidine (CYP3A4 substrates)
Co-administration of posaconazole and terfenadine, astemizole, cisapride, pimozide, halofantrine orquinidine is contraindicated. Co-administration may result in increased plasma concentrations of thesemedicinal products, leading to QTc prolongation and rare occurrences of torsades de pointes (seesection 4.3).
Ergot alkaloids
Posaconazole may increase the plasma concentration of ergot alkaloids (ergotamine anddihydroergotamine), which may lead to ergotism. Co-administration of posaconazole and ergotalkaloids is contraindicated (see section 4.3).
HMG-CoA reductase inhibitors metabolised through CYP3A4 (e.g. simvastatin, lovastatin, andatorvastatin)
Posaconazole may substantially increase plasma levels of HMG-CoA reductase inhibitors that aremetabolised by CYP3A4. Treatment with these HMG-CoA reductase inhibitors should bediscontinued during treatment with posaconazole as increased levels have been associated withrhabdomyolysis (see section 4.3).
Vinca alkaloids
Most of the vinca alkaloids (e.g., vincristine and vinblastine) are substrates of CYP3A4. Concomitantadministration of azole antifungals, including posaconazole, with vincristine has been associated withserious adverse reactions (see section 4.4). Posaconazole may increase the plasma concentrations ofvinca alkaloids which may lead to neurotoxicity and other serious adverse reactions. Therefore,reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, includingvincristine, who have no alternative antifungal treatment options.
RifabutinPosaconazole increased the Cmax and AUC of rifabutin by 31 % and 72 %, respectively. Concomitantuse of posaconazole and rifabutin should be avoided unless the benefit to the patient outweighs therisk (see also above regarding the effect of rifabutin on plasma levels of posaconazole). If thesemedicinal products are co-administered, careful monitoring of full blood counts and adverse reactionsrelated to increased rifabutin levels (e.g. uveitis) is recommended.
SirolimusRepeat dose administration of posaconazole oral suspension (400 mg twice daily for 16 days)increased the Cmax and AUC of sirolimus (2 mg single dose) an average of 6.7-fold and 8.9-fold (range3.1 to 17.5-fold), respectively, in healthy subjects. The effect of posaconazole on sirolimus in patientsis unknown, but is expected to be variable due to the variable posaconazole exposure in patients.
Co-administration of posaconazole with sirolimus is not recommended and should be avoidedwhenever possible. If it is considered that co-administration is unavoidable, then it is recommendedthat the dose of sirolimus should be greatly reduced at the time of initiation of posaconazole therapyand that there should be very frequent monitoring of trough concentrations of sirolimus in wholeblood. Sirolimus concentrations should be measured upon initiation, during co-administration, and atdiscontinuation of posaconazole treatment, with sirolimus doses adjusted accordingly. It should benoted that the relationship between sirolimus trough concentration and AUC is changed duringco-administration with posaconazole. As a result, sirolimus trough concentrations that fall within theusual therapeutic range may result in sub-therapeutic levels. Therefore, trough concentrations that fallin the upper part of the usual therapeutic range should be targeted and careful attention should be paidto clinical signs and symptoms, laboratory parameters and tissue biopsies.
CiclosporinIn heart transplant patients on stable doses of ciclosporin, posaconazole oral suspension 200 mg oncedaily increased ciclosporin concentrations requiring dose reductions. Cases of elevated ciclosporinlevels resulting in serious adverse reactions, including nephrotoxicity and one fatal case ofleukoencephalopathy, were reported in clinical efficacy studies. When initiating treatment withposaconazole in patients already receiving ciclosporin, the dose of ciclosporin should be reduced (e.g.
to about three quarters of the current dose). Thereafter blood levels of ciclosporin should be monitoredcarefully during co-administration, and upon discontinuation of posaconazole treatment, and the doseof ciclosporin should be adjusted as necessary.
TacrolimusPosaconazole increased Cmax and AUC of tacrolimus (0.05 mg/kg body weight single dose) by 121 %and 358%, respectively. Clinically significant interactions resulting in hospitalisation and/orposaconazole discontinuation were reported in clinical efficacy studies. When initiating posaconazoletreatment in patients already receiving tacrolimus, the dose of tacrolimus should be reduced (e.g. toabout one third of the current dose). Thereafter blood levels of tacrolimus should be monitoredcarefully during co-administration, and upon discontinuation of posaconazole, and the dose oftacrolimus should be adjusted as necessary.
HIV Protease inhibitorsAs HIV protease inhibitors are CYP3A4 substrates, it is expected that posaconazole will increaseplasma levels of these antiretroviral agents. Following co-administration of posaconazole oralsuspension (400 mg twice daily) with atazanavir (300 mg once daily) for 7 days in healthy subjects
Cmax and AUC of atazanavir increased by an average of 2.6-fold and 3.7-fold (range 1.2 to 26-fold),respectively. Following co-administration of posaconazole oral suspension (400 mg twice daily) withatazanavir and ritonavir (300/100 mg once daily) for 7 days in healthy subjects Cmax and AUC ofatazanavir increased by an average of 1.5-fold and 2.5-fold (range 0.9 to 4.1-fold), respectively. Theaddition of posaconazole to therapy with atazanavir or with atazanavir plus ritonavir was associatedwith increases in plasma bilirubin levels. Frequent monitoring for adverse reactions and toxicityrelated to antiretroviral agents that are substrates of CYP3A4 is recommended during co-administration with posaconazole.
Midazolam and other benzodiazepines metabolised by CYP3A4
In a study in healthy volunteers posaconazole oral suspension (200 mg once daily for 10 days)increased the exposure (AUC) of intravenous midazolam (0.05 mg/kg) by 83 %. In another study inhealthy volunteers, repeat dose administration of posaconazole oral suspension (200 mg twice dailyfor 7 days) increased the Cmax and AUC of intravenous midazolam (0.4 mg single dose) by an averageof 1.3- and 4.6-fold (range 1.7 to 6.4-fold), respectively; Posaconazole oral suspension 400 mg twicedaily for 7 days increased the intravenous midazolam Cmax and AUC by 1.6 and 6.2-fold (range 1.6 to7.6-fold), respectively. Both doses of posaconazole increased Cmax and AUC of oral midazolam (2 mgsingle oral dose) by 2.2 and 4.5-fold, respectively. In addition, posaconazole oral suspension (200 mgor 400 mg) prolonged the mean terminal half-life of midazolam from approximately 3-4 hours to8-10 hours during co-administration.
Due to the risk of prolonged sedation it is recommended that dose adjustments should be consideredwhen posaconazole is administered concomitantly with any benzodiazepine that is metabolised by
CYP3A4 (e.g. midazolam, triazolam, alprazolam) (see section 4.4).
Calcium channel blockers metabolised through CYP3A4 (e.g. diltiazem, verapamil, nifedipine,nisoldipine)
Frequent monitoring for adverse reactions and toxicity related to calcium channel blockers isrecommended during co-administration with posaconazole. Dose adjustment of calcium channelblockers may be required.
DigoxinAdministration of other azoles has been associated with increases in digoxin levels. Therefore,posaconazole may increase plasma concentration of digoxin and digoxin levels need to be monitoredwhen initiating or discontinuing posaconazole treatment.
Sulfonylureas
Glucose concentrations decreased in some healthy volunteers when glipizide was co-administeredwith posaconazole. Monitoring of glucose concentrations is recommended in diabetic patients.
All-trans retinoic acid (ATRA) or tretinoin
As ATRA is metabolised by the hepatic CYP450 enzymes, notably CYP3A4, concomitantadministration with posaconazole, which is a strong inhibitor of CYP3A4, may lead to increasedexposure to tretinoin resulting in an increased toxicity (especially hypercalcaemia). Serum calciumlevels should be monitored and, if needed, appropriate dose adjustments of tretinoin shouldbeconsidered during the treatment with posaconazole, and during the following days after treatment.
Venetoclax
Compared with venetoclax 400 mg administered alone, co-administration of 300 mg posaconazole, astrong CYP3A inhibitor, with venetoclax 50 mg and 100 mg for 7 days in 12 patients, increasedvenetoclax Cmax to 1.6-fold and 1.9-fold, and AUC to 1.9-fold and 2.4-fold, respectively (see sections4.3 and 4.4).
Refer to the venetoclax SmPC.
Paediatric populationInteraction studies have only been performed in adults.
4.6 Fertility, pregnancy and lactation
PregnancyThere is insufficient information on the use of posaconazole in pregnant women. Studies in animalshave shown reproductive toxicity (see section 5.3). The potential risk for humans is unknown.
Women of childbearing potential have to use effective contraception during treatment. Posaconazolemust not be used during pregnancy unless the benefit to the mother clearly outweighs the potential riskto the foetus.
Breast-feedingPosaconazole is excreted into the milk of lactating rats (see section 5.3). The excretion ofposaconazole in human breast milk has not been investigated. Breast-feeding must be stopped oninitiation of treatment with posaconazole.
FertilityPosaconazole had no effect on fertility of male rats at doses up to 180 mg/kg (3.4 times the 300 mgtablet based on steady-state plasma concentrations in patients) or female rats at a dose up to 45 mg/kg(2.6 times the 300-mg tablet based on steady-state plasma concentrations in patients). There is noclinical experience assessing the impact of posaconazole on fertility in humans.
4.7 Effects on ability to drive and use machines
Since certain adverse reactions (e.g. dizziness, somnolence, etc.) have been reported withposaconazole use, which potentially may affect driving/operating machinery, caution needs to be used.
4.8 Undesirable effects
Summary of the safety profileSafety data mainly derive from studies with the oral suspension.
The safety of posaconazole oral suspension has been assessed in > 2,400 patients and healthyvolunteers enrolled in clinical studies and from post-marketing experience. The most frequentlyreported serious related adverse reactions included nausea, vomiting, diarrhoea, pyrexia, and increasedbilirubin.
Posaconazole tablets
The safety of posaconazole tablet has been assessed in 104 healthy volunteers and 230 patientsenrolled in a clinical study of antifungal prophylaxis.
The safety of posaconazole concentrate for solution for infusion and posaconazole tablet has beenassessed in 288 patients enrolled in a clinical study of aspergillosis of whom 161 patients received theconcentrate for solution for infusion and 127 patients received the tablet formulation.
The tablet formulation was investigated in AML and MDS patients and those after HSCT with or atrisk for Graft versus Host Disease (GVHD) only. Maximum duration of exposure to the tabletformulation was shorter than with the oral suspension. Plasma exposure resulting from the tabletformulation was higher than observed with the oral suspension.
The safety of posaconazole tablets has been assessed in 230 patients enrolled in the pivotal clinicalstudy. Patients were enrolled in a non-comparative pharmacokinetic and safety study of posaconazoletablets when given as antifungal prophylaxis. Patients were immunocompromised with underlyingconditions including haematological malignancy, neutropenia post-chemotherapy, GVHD, and post
HSCT. Posaconazole therapy was given for a median duration of 28 days. Twenty patients received200 mg daily dose and 210 patients received 300 mg daily dose (following twice daily dosing on
Day 1 in each cohort).
The safety of posaconazole tablets and concentrate for solution for infusion were also investigated in acontrolled study of treatment of invasive aspergillosis. The maximum duration of invasiveaspergillosis treatment was similar to that studied with the oral suspension for salvage treatment andwas longer than that with the tablets or concentrate for solution for infusion in prophylaxis.

Posaconazole is not removed by haemodialysis. There is no special treatment available in the case ofoverdose with posaconazole. Supportive care may be considered.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antimycotics for systemic use, Triazole and tetrazole derivatives, ATCcode: J02AC04
Mechanism of actionPosaconazole inhibits the enzyme lanosterol 14α-demethylase (CYP51), which catalyses an essentialstep in ergosterol biosynthesis.
MicrobiologyPosaconazole has been shown in vitro to be active against the following microorganisms: Aspergillusspecies (Aspergillus fumigatus, A. flavus, A. terreus, A. nidulans, A. niger, A. ustus), Candida species(Candida albicans, C. glabrata, C. krusei, C. parapsilosis, C. tropicalis, C. dubliniensis, C. famata, C.
inconspicua, C. lipolytica, C. norvegensis, C. pseudotropicalis), Coccidioides immitis, Fonsecaeapedrosoi, and species of Fusarium, Rhizomucor, Mucor, and Rhizopus. The microbiological datasuggest that posaconazole is active against Rhizomucor, Mucor, and Rhizopus; however, the clinicaldata are currently too limited to assess the efficacy of posaconazole against these causative agents.
The following in vitro data are available, but their clinical significance is unknown. In a surveillancestudy of > 3,000 clinical mold isolates from 2010-2018, 90 % of non-Aspergillus fungi exhibited thefollowing in vitro minimum inhibitory concentration (MIC): Mucorales spp (n=81) of 2 mg/L;
Scedosporium apiospermum/S. boydii (n=65) of 2 mg/L; Exophiala dermatiditis (n=15) of 0.5 mg/L,and Purpureocillium lilacinum (n=21) of 1 mg/L.
ResistanceClinical isolates with decreased susceptibility to posaconazole have been identified. The principlemechanism of resistance is the acquisition of substitutions in the target protein, CYP51.
Epidemiological Cut-off (ECOFF) Values for Aspergillus spp.
The ECOFF values for posaconazole, which distinguish the wild type population from isolates withacquired resistance, have been determined by EUCAST methodology.
EUCAST ECOFF values:
- Aspergillus flavus: 0.5 mg/L
- Aspergillus fumigatus: 0.5 mg/L
- Aspergillus nidulans: 0.5 mg/L
- Aspergillus niger: 0.5 mg/L
- Aspergillus terreus: 0.25 mg/L
There are currently insufficient data to set clinical breakpoints for Aspergillus spp. ECOFF values donot equate to clinical breakpoints.
BreakpointsSusceptibility testing breakpoints
MIC (minimum inhibitory concentration) interpretive criteria for susceptibility testing have beenestablished by the European Committee on Antimicrobial Susceptibility Testing (EUCAST) for
Posaconazole and are listed here: <https://www.ema.europa.eu/documents/other/minimum-inhibitory-concentration-mic-breakpoints_en.xlsx>
Combination with other antifungal agents
The use of combination antifungal therapies should not decrease the efficacy of either posaconazole orthe other therapies; however, there is currently no clinical evidence that combination therapy willprovide an added benefit.
Clinical experienceSummary of posaconazole concentrate for solution for infusion and tablet study invasive aspergillosis
The safety and efficacy of posaconazole for the treatment of patients with invasive aspergillosis wasevaluated in a double-blind controlled study (study-69) in 575 patients with proven, probable, orpossible invasive fungal infections per EORTC/MSG criteria.
Patients were treated with posaconazole (n=288) concentrate for solution for infusion or tablet given ata dose of 300 mg QD (BID on Day 1). Comparator patients were treated with voriconazole (n=287)given IV at a dose of 6 mg/kg BID Day 1 followed by 4 mg/kg BID, or orally at a dose of 300 mg BID
Day 1 followed by 200 mg BID. Median treatment duration was 67 days (posaconazole) and 64 days(voriconazole).
In the intent-to-treat (ITT) population (all subjects who received at least one dose of study drug), 288patients received posaconazole and 287 patients received voriconazole. The full analysis setpopulation (FAS) is the subset of all subjects within the ITT population who were classified byindependent adjudication as having proven or probable invasive aspergillosis: 163 subjects forposaconazole and 171 subjects for voriconazole. The all-cause mortality and global clinical responsein these two populations are presented in Table 3 and 4, respectively.

Summary of posaconazole tablet bridging study
Study 5615 was a non-comparative multi-centre study performed to evaluate the pharmacokineticproperties, safety, and tolerability of posaconazole tablet. Study 5615 was conducted in a similarpatient population to that previously studied in the pivotal posaconazole oral suspension clinicalprogram. The pharmacokinetics and safety data from Study 5615 were bridged to the existing data(including efficacy data) with the oral suspension.
The subject population included: 1) patients with AML or MDS who had recently receivedchemotherapy and had developed or were anticipated to develop significant neutropenia, or 2) patientswho had undergone a HSCT and were receiving immunosuppressive therapy for prevention ortreatment of GVHD. Two different dosing groups were evaluated: 200 mg twice daily on Day 1,followed by 200 mg once daily thereafter (Part IA) and 300 mg twice daily on Day 1, followed by300 mg once daily thereafter (Part 1B and Part 2).
Serial PK samples were collected on Day 1 and at steady-state on Day 8 for all Part 1 subjects and asubset of Part 2 subjects. Moreover, sparse PK samples were collected at several days during steadystate before the next dose (Cmin) for a larger subject population. Based on average Cmin concentrations,a predicted average concentration (Cav) could be calculated for 186 subjects dosed with 300 mg. PKanalysis in patients of Cav found that 81 % of the subjects treated with the 300 mg once daily doseattained steady state predicted Cav between 500-2,500 ng/mL. One subject (< 1%) had a predicted
Cav below 500 ng/mL and 19 % of the subjects had a predicted Cav above 2,500 ng/mL. Subjectsachieved a mean predicted Cav at steady state of 1,970 ng/mL.
In Table 5 a comparison is shown of exposure (Cav) after administration of posaconazole tablet andposaconazole oral suspension at therapeutic doses in patients depicted as quartile analysis. Exposuresafter tablet administration are generally higher than, but overlapping with, exposures afteradministration of posaconazole oral suspension.

Summary of posaconazole oral suspension studies
Invasive aspergillosis
Oral posaconazole suspension 800 mg/day in divided doses was evaluated for the treatment ofinvasive aspergillosis in patients with disease refractory to amphotericin B (including liposomalformulations) or itraconazole or in patients who were intolerant of these medicinal products in a non-comparative salvage therapy study (Study 0041). Clinical outcomes were compared with those in anexternal control group derived from a retrospective review of medical records. The external controlgroup included 86 patients treated with available therapy (as above) mostly at the same time and at thesame sites as the patients treated with posaconazole. Most of the cases of aspergillosis were consideredto be refractory to prior therapy in both the posaconazole group (88 %) and in the external controlgroup (79 %).
As shown in Table 6, a successful response (complete or partial resolution) at the end of treatment wasseen in 42 % of posaconazole-treated patients compared to 26 % of the external group. However, thiswas not a prospective, randomized controlled study and so all comparisons with the external controlgroup should be viewed with caution.

Fusarium spp.11 of 24 patients who had proven or probable fusariosis were successfully treated with posaconazoleoral suspension 800 mg/day in divided doses for a median of 124 days and up to 212 days. Amongeighteen patients who were intolerant or had infections refractory to amphotericin B or itraconazole,seven patients were classed as responders.
Chromoblastomycosis/Mycetoma9 of 11 patients were successfully treated with posaconazole oral suspension 800 mg/day in divideddoses for a median of 268 days and up to 377 days. Five of these patients had chromoblastomycosisdue to Fonsecaea pedrosoi and 4 had mycetoma, mostly due to Madurella species.
Coccidioidomycosis11 of 16 patients were successfully treated (at the end of treatment complete or partial resolution ofsigns and symptoms present at baseline) with posaconazole oral suspension 800 mg/day in divideddoses for a median of 296 days and up to 460 days.
Prophylaxis of Invasive Fungal Infections (IFIs) (Studies 316 and 1899)
Two randomized, controlled prophylaxis studies were conducted among patients at high-risk fordeveloping invasive fungal infections.
Study 316 was a randomized, double-blind study of posaconazole oral suspension (200 mg three timesa day) versus fluconazole capsules (400 mg once daily) in allogeneic hematopoietic stem celltransplant recipients with graft-versus-host disease (GVHD). The primary efficacy endpoint was theincidence of proven/probable IFIs at 16 weeks post-randomization as determined by an independent,blinded external expert panel. A key secondary endpoint was the incidence of proven/probable IFIsduring the on-treatment period (first dose to last dose of study medicinal product + 7 days). Themajority (377/600, [63 %]) of patients included had Acute Grade 2 or 3 or chronic extensive (195/600,[32.5 %]) GVHD at study start. The mean duration of therapy was 80 days for posaconazole and 77days for fluconazole.
Study 1899 was a randomized, evaluator-blinded study of posaconazole oral suspension (200 mg threetimes a day) versus fluconazole suspension (400 mg once daily) or itraconazole oral solution (200 mgtwice a day) in neutropenic patients who were receiving cytotoxic chemotherapy for acutemyelogenous leukaemia or myelodysplastic syndromes. The primary efficacy endpoint was theincidence of proven/probable IFIs as determined by an independent, blinded external expert panelduring the on-treatment period. A key secondary endpoint was the incidence of proven/probable IFIsat 100 days post-randomization. New diagnosis of acute myelogenous leukaemia was the mostcommon underlying condition (435/602, [72 %]). The mean duration of therapy was 29 days forposaconazole and 25 days for fluconazole/itraconazole.
In both prophylaxis studies, aspergillosis was the most common breakthrough infection. See Table 7and 8 for results from both studies. There were fewer breakthrough Aspergillus infections in patientsreceiving posaconazole prophylaxis when compared to control patients.

In Study 1899, a significant decrease in all cause mortality in favour of posaconazole was observed[POS 49/304 (16 %) vs. FLU/ITZ 67/298 (22 %) p= 0.048]. Based on Kaplan-Meier estimates, theprobability of survival up to day 100 after randomization, was significantly higher for posaconazolerecipients; this survival benefit was demonstrated when the analysis considered all causes of death (P=0.0354) as well as IFI-related deaths (P = 0.0209).
In Study 316, overall mortality was similar (POS, 25 %; FLU, 28 %); however, the proportion of
IFI- related deaths was significantly lower in the POS group (4/301) compared with the FLU group(12/299; P= 0.0413).
Paediatric populationThere is limited paediatric experience for posaconazole tablets.
Three patients 14-17 years of age were treated with posaconazole concentrate for solution for infusionand tablet 300 mg/day (BID on Day 1 followed by QD thereafter) in the study of treatment of invasiveaspergillosis.
The safety and efficacy of posaconazole (Posaconazole gastro-resistant powder and solvent for oralsuspension; Posaconazole concentrate for solution for infusion) have been established in paediatricpatients 2 to less than 18 years of age. Use of posaconazole in these age groups is supported byevidence from adequate and well-controlled studies of posaconazole in adults and pharmacokineticand safety data from paediatric studies (see section 5.2). No new safety signals associated with the useof posaconazole in paediatric patients were identified in the paediatric studies (see section 4.8).
Safety and efficacy in paediatric patients below the age of 2 years have not been established.
No data are available.
Electrocardiogram evaluation
Multiple, time-matched ECGs collected over a 12 hour period were obtained before and duringadministration of posaconazole oral suspension (400 mg twice daily with high fat meals) from173 healthy male and female volunteers aged 18 to 85 years. No clinically relevant changes in themean QTc (Fridericia) interval from baseline were observed.
5.2 Pharmacokinetic properties
Pharmacokinetic/Pharmacodynamic relationships
A correlation between total medicinal product exposure divided by MIC (AUC/MIC) and clinicaloutcome was observed. The critical ratio for subjects with Aspergillus infections was ~200. It isparticularly important to try to ensure that maximal plasma levels are achieved in patients infectedwith Aspergillus (see sections 4.2 and 5.2 on recommended dose regimens).
AbsorptionPosaconazole tablets are absorbed with a median Tmax of 4 to 5 hours and exhibits dose proportionalpharmacokinetics after single and multiple dosing up to 300 mg.
Following a single dose administration of 300 mg posaconazole tablets after a high fat meal to healthyvolunteers, the AUC0-72 hours and Cmax were higher compared to administration under fasted condition(51 % and 16 % for AUC0-72 hours and Cmax respectively). Based on a population pharmacokineticmodel, posaconazole Cav is increased 20 % when given with a meal compared to a fasted state.
Posaconazole plasma concentrations following administration of posaconazole tablets may increaseover time in some patients. The reason for this time-dependency is not completely understood.
DistributionPosaconazole, after administration of the tablet, has a mean apparent volume of distribution of 394 L(42 %), ranging between 294-583 L among the studies in healthy volunteers.
Posaconazole is highly protein bound (> 98 %), predominantly to serum albumin.
BiotransformationPosaconazole does not have any major circulating metabolites and its concentrations are unlikely to bealtered by inhibitors of CYP450 enzymes. Of the circulating metabolites, the majority are glucuronideconjugates of posaconazole with only minor amounts of oxidative (CYP450 mediated) metabolitesobserved. The excreted metabolites in urine and faeces account for approximately 17 % of theadministered radiolabelled dose.
EliminationPosaconazole after administration of the tablets, is slowly eliminated with a mean half-life (t½) of29 hours (range 26 to 31 hours) and a mean apparent clearance ranging from 7.5 to 11 L/hr. Afteradministration of 14C-posaconazole, radioactivity was predominantly recovered in the faeces (77% ofthe radiolabelled dose) with the major component being parent compound (66 % of the radiolabelleddose). Renal clearance is a minor elimination pathway, with 14 % of the radiolabelled dose excreted inurine (< 0.2 % of the radiolabelled dose is parent compound). Steady-state plasma concentrations areattained by Day 6 at the 300 mg dose (once daily after twice daily loading dose at Day 1).
Pharmacokinetics in special populationsBased on a population pharmacokinetic model evaluating posaconazole pharmacokinetics, steady stateplasma concentrations were predicted in patients administered posaconazole concentrate for solutionfor infusion or tablets 300 mg once a day following BID dosing on Day 1 for the treatment of invasiveaspergillosis and prophylaxis of invasive fungal infections.

The population pharmacokinetic analysis of posaconazole in patients suggests that race, sex, renalimpairment and disease (prophylaxis or treatment) have no clinically meaningful effect on thepharmacokinetics of posaconazole.
Children (< 18 years)
There is limited (n=3) paediatric experience with posaconazole tablets.
The pharmacokinetics of posaconazole oral suspension have been evaluated in paediatric patients.
Following administration of 800 mg per day of posaconazole oral suspension as a divided dose fortreatment of invasive fungal infections, mean trough plasma concentrations from 12 patients8 -17 years of age (776 ng/mL) were similar to concentrations from 194 patients 18 - 64 years of age(817 ng/mL). No pharmacokinetic data are available from paediatric patients less than 8 years of age.
Similarly, in the prophylaxis studies, the mean steady-state posaconazole average concentration (Cav)was comparable among ten adolescents (13-17 years of age) to Cav achieved in adults (≥ 18 years ofage).
GenderThe pharmacokinetics of posaconazole tablets are comparable in men and women.
ElderlyNo overall differences in safety were observed between the geriatric patients and younger patients.
The population pharmacokinetic model of posaconazole concentrate for solution for infusion andtablets indicates that posaconazole clearance is related to age. Posaconazole Cav is generallycomparable between young and elderly patients (≥ 65 years of age); however, the Cav is increased by11 % in the very elderly (≥ 80 years). It is, therefore, suggested to closely monitor very elderly patients(≥ 80 years) for adverse events.
The pharmacokinetics of posaconazole tablets are comparable in young and elderly subjects(≥ 65 years of age).
Pharmacokinetic differences based upon age are not considered to be clinically relevant; therefore, nodose adjustment is required.
RaceThere is insufficient data among different races with posaconazole tablets.
There was a slight decrease (16 %) in the AUC and Cmax of posaconazole oral suspension in Blacksubjects relative to Caucasian subjects. However, the safety profile of posaconazole between the Blackand Caucasian subjects was similar.
Weight
The population pharmacokinetic model of posaconazole concentrate for solution for infusion andtablets indicates that posaconazole clearance is related to weight. In patients > 120 kg, the Cav isdecreased by 25 % and in patients <50 kg, the Cav is increased by 19 %. It is, therefore, suggested toclosely monitor for breakthrough fungal infections in patients weighing more than 120 kg.
Renal impairmentFollowing single-dose administration of posaconazole oral suspension, there was no effect of mild andmoderate renal impairment (n=18, Cl cr ≥ 20 mL/min/1.73 m2) on posaconazole pharmacokinetics;therefore, no dose adjustment is required. In subjects with severe renal impairment (n=6,
Cl 2cr< 20 mL/min/1.73 m ), the AUC of posaconazole was highly variable [> 96 % CV (coefficient ofvariance)] compared to other renal groups [< 40 % CV]. However, as posaconazole is not significantlyrenally eliminated, an effect of severe renal impairment on the pharmacokinetics of posaconazole isnot expected and no dose adjustment is recommended. Posaconazole is not removed by haemodialysis.
Similar recommendations apply to posaconazole tablets; however, a specific study has not beenconducted with the posaconazole tablets.
Hepatic impairmentAfter a single oral dose of 400 mg posaconazole oral suspension to patients with mild (Child-Pugh
Class A), moderate (Child-Pugh Class B) or severe (Child-Pugh Class C) hepatic impairment (six pergroup), the mean AUC was 1.3 to 1.6-fold higher compared to that for matched control subjects withnormal hepatic function. Unbound concentrations were not determined and it cannot be excluded thatthere is a larger increase in unbound posaconazole exposure than the observed 60 % increase in total
AUC. The elimination half-life (t½) was prolonged from approximately 27 hours up to ~43 hours inrespective groups. No dose adjustment is recommended for patients with mild to severe hepaticimpairment but caution is advised due to the potential for higher plasma exposure.
Similar recommendations apply to posaconazole tablets; however, a specific study has not beenconducted with the posaconazole tablets.
5.3 Preclinical safety data
As observed with other azole antifungal agents, effects related to inhibition of steroid hormonesynthesis were seen in repeated-dose toxicity studies with posaconazole. Adrenal suppressive effectswere observed in toxicity studies in rats and dogs at exposures equal to or greater than those obtainedat therapeutic doses in humans.
Neuronal phospholipidosis occurred in dogs dosed for ≥ 3 months at lower systemic exposures thanthose obtained at therapeutic doses in humans. This finding was not seen in monkeys dosed for oneyear. In twelve-month neurotoxicity studies in dogs and monkeys, no functional effects were observedon the central or peripheral nervous systems at systemic exposures greater than those achievedtherapeutically.
Pulmonary phospholipidosis resulting in dilatation and obstruction of the alveoli was observed in the2-year study in rats. These findings are not necessarily indicative of a potential for functional changesin humans.
No effects on electrocardiograms, including QT and QTc intervals, were seen in a repeat dose safetypharmacology study in monkeys at maximal plasma concentrations 8.5-fold greater than theconcentrations obtained at therapeutic doses in humans. Echocardiography revealed no indication ofcardiac decompensation in a repeat dose safety pharmacology study in rats at a systemic exposure2.1-fold greater than that achieved therapeutically. Increased systolic and arterial blood pressures (upto 29 mm-Hg) were seen in rats and monkeys at systemic exposures 2.1-fold and 8.5-fold greater,respectively, than those achieved with the human therapeutic doses.
Reproduction, peri- and postnatal development studies were conducted in rats. At exposures lowerthan those obtained at therapeutic doses in humans, posaconazole caused skeletal variations andmalformations, dystocia, increased length of gestation, reduced mean litter size and postnatal viability.
In rabbits, posaconazole was embryotoxic at exposures greater than those obtained at therapeuticdoses. As observed with other azole antifungal agents, these effects on reproduction were consideredto be due to a treatment-related effect on steroidogenesis.
Posaconazole was not genotoxic in in vitro and in vivo studies. Carcinogenicity studies did not revealspecial hazards for humans.
In a nonclinical study using intravenous administration of posaconazole in very young dogs (dosedfrom 2-8 weeks of age) an increase in the incidence of brain ventricle enlargement was observed intreated animals as compared with concurrent control animals. No difference in the incidence of brainventricle enlargement between control and treated animals was observed following the subsequent5 month treatment-free period. There were no neurologic, behavioural or developmental abnormalitiesin the dogs with this finding, and a similar brain finding was not seen with either oral posaconazoleadministration to juvenile dogs (4 days to 9 months of age) or intravenous posaconazoleadministration to juvenile dogs (10 weeks to 23 weeks of age). The clinical significance of this findingis unknown.
