1.2Prophylaxis of Invasive Aspergillus and Candida Infections Posaconazole delayed-release tablets are indicated for the prophylaxis of invasive Aspergillus and Candida infections in patients who are at high risk of developing these infections due to being severely immunocompromised, such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD) or those with hematologic malignancies with prolonged neutropenia from chemotherapy as follows: Posaconazole delayed-release tablets: adults and pediatric patients 2 years of age and older who weigh greater than 40 kg Additional Pediatric Use information is approved for Merck Sharp & Dohme Corp.’s NOXAFIL (posaconazole) delayed-release tablets.
However, due to Merck Sharp & Dohme Corp.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Posaconazole delayed-release tablets formulations are supplied in different dose strengths of posaconazole, are approved for different indications, age groups, and weights, have different dosages and duration of therapy; and have different preparation and administration instructions. (2.1) Noxafil oral suspension is not substitutable with posaconazole delayed-release tablets or Noxafil PowderMix for delayed-release oral suspension due to the differences in the dosing of each formulation. Therefore, follow the specific dosage recommendations for each of the formulations.
(2.1 , 2.2 , 2.3) Administer posaconazole delayed-release tablets with or without food. (2.1) See the full prescribing information for important administration instructions and preparation instructions for posaconazole delayed -release tablets (2.7 , 2.9) For adult and pediatric patients aged 2 years of age and older, see the Full Prescribing Information for dosing recommendations for posaconazole delayed-release tablets, based on the indication, age, and weight associated with the dosage form (1.2 , 2.1 , 2.2 , 2.3)
2.1Important Administration Instructions Noxafil injection, posaconazole delayed-release tablets, Noxafil oral suspension and Noxafil PowderMix for delayed-release oral suspension are supplied in different dose strengths of posaconazole, are approved for different indications, age groups and weights; have different dosages and duration of therapy; and have different preparation and administration instructions. Therefore, select the recommended dosage form based on the indication, age group, and weight and carefully follow the recommended dosage, preparation and administration instructions described for each product [see Dosage and Administration (2.2 to 2.11) ] , and the following important administration instructions described below.
Non-substitutable Noxafil oral suspension is not substitutable with posaconazole delayed-release tablets or Noxafil PowderMix for delayed-release oral suspension due to the differences in the dosing of each formulation. Therefore, follow the specific dosage recommendations for each of the formulations [see Dosage and Administration (2.2 , 2.3) ] . Posaconazole delayed-release tablets Swallow tablets whole.
Do not divide, crush, or chew. Administer with or without food [see Dosage and Administration (2.7) and Clinical Pharmacology (12.3) ] . For patients who cannot eat a full meal, posaconazole delayed-release tablets should be used instead of Noxafil oral suspension for the prophylaxis indication.
Posaconazole delayed-release tablets generally provide higher plasma drug exposures than Noxafil oral suspension under both fed and fasted conditions, and therefore is the preferred oral formulation for the prophylaxis indication.
2.2Recommended Dosage of Posaconazole Delayed-Release Tablets in Adult Patients The recommended dosage of posaconazole delayed-release tablets in adult patients for the prophylaxis of invasive Aspergillus and Candida infections in patients who are at high risk of developing these infections due to being severely immunocompromised is shown in Table 1 [see Dosage and Administration (2.7 , 2.9) and Clinical Pharmacology (12.3) ] . Table 1: Recommended Dosage of Posaconazole Delayed-Release Tablets in Adult Patients Dosage Duration of Therapy Prophylaxis of Invasive Aspergillus and Candida Infections Posaconazole Delayed-Release Tablets: Loading dose: 300 mg (three 100 mg delayed-release tablets) twice a day on the first day.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Known hypersensitivity to posaconazole or other azole antifungal agents. (4.1) Co-administration of posaconazole with the following drugs is contraindicated; posaconazole increases concentrations and toxicities of: Sirolimus (4.2 , 7.2) CYP3A4 substrates (pimozide, quinidine): can result in QTc interval prolongation and cases of torsades de pointes (TdP) (4.3 , 5.2 , 7.2) HMG-CoA Reductase Inhibitors Primarily Metabolized through CYP3A4 (4.4 , 7.2) Ergot alkaloids (4.5 , 7.2) Venetoclax: In patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) at initiation and during the ramp-up phase (4.6 , 5.11 , 7.2)
4.1Hypersensitivity Posaconazole delayed-release tablets are contraindicated in persons with known hypersensitivity to posaconazole or other azole antifungal agents.
4.2Use with Sirolimus Posaconazole is contraindicated with sirolimus. Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] .
4.3QT Prolongation with Concomitant Use with CYP3A4 Substrates Posaconazole is contraindicated with CYP3A4 substrates that prolong the QT interval. Concomitant administration of posaconazole with the CYP3A4 substrates, pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and cases of torsades de pointes [see Warnings and Precautions (5.2) and Drug Interactions (7.2) ] .
4.4HMG-CoA Reductase Inhibitors Primarily Metabolized Through CYP3A4 Co-administration with the HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) is contraindicated since increased plasma concentration of these drugs can lead to rhabdomyolysis [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] .
4.5Use with Ergot Alkaloids Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.2) ] .
4.6Use with Venetoclax Co-administration of posaconazole with venetoclax at initiation and during the ramp-up phase is contraindicated in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) due to the potential for increased risk of tumor lysis syndrome [see Warnings and Precautions (5.11) and Drug Interactions (7.2) ] .
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Calcineurin-Inhibitor Toxicity: Posaconazole increases concentrations of cyclosporine or tacrolimus; reduce dose of cyclosporine and tacrolimus and monitor concentrations frequently. (5.1) Arrhythmias and QTc Prolongation: Posaconazole has been shown to prolong the QTc interval and cause cases of TdP. Administer with caution to patients with potentially proarrhythmic conditions.
Do not administer with drugs known to prolong QTc interval and metabolized through CYP3A4. (5.2 , 7.2) Electrolyte Disturbances: Monitor and correct, especially those involving potassium (K + ), magnesium (Mg ++ ), and calcium (Ca ++ ), before and during posaconazole therapy. (5.3) Pseudoaldosteronism: Manifested by the onset or worsening of hypertension, and abnormal laboratory findings.
Monitor blood pressure and potassium levels, and manage as necessary. (5.4) Hepatic Toxicity: Elevations in liver tests may occur. Discontinuation should be considered in patients who develop abnormal liver tests or monitor liver tests during treatment.
(5.5) Concomitant Use with Midazolam: Posaconazole can prolong hypnotic/sedative effects. Monitor patients and benzodiazepine receptor antagonists should be available. (5.7 , 7.2) Vincristine Toxicity: Concomitant administration of azole antifungals, including posaconazole, with vincristine has been associated with neurotoxicity and other serious adverse reactions; reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options.
(5.8 , 7.2) Breakthrough Fungal Infections: Monitor patients with severe diarrhea or vomiting when receiving posaconazole delayed-release tablets. (5.10) Venetoclax Toxicity: Concomitant administration of posaconazole with venetoclax may increase venetoclax toxicities, including the risk of tumor lysis syndrome, neutropenia, and serious infections; monitor for toxicity and reduce venetoclax dose. (4.6 , 5.11 , 7.2)
5.1Calcineurin-Inhibitor Toxicity Concomitant administration of posaconazole with cyclosporine or tacrolimus increases the whole blood trough concentrations of these calcineurin-inhibitors [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . Nephrotoxicity and leukoencephalopathy (including deaths) have been reported in clinical efficacy studies in patients with elevated cyclosporine or tacrolimus concentrations. Frequent monitoring of tacrolimus or cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus or cyclosporine dose adjusted accordingly.
5.2Arrhythmias and QT Prolongation Some azoles, including posaconazole, have been associated with prolongation of the QT interval on the electrocardiogram. In addition, cases of torsades de pointes have been reported in patients taking posaconazole. Results from a multiple time-matched ECG analysis in healthy volunteers did not show any increase in the mean of the QTc interval.
Multiple, time-matched ECGs collected over a 12-hour period were recorded at baseline and steady-state from 173 healthy male and female volunteers (18 to 85 years of age) administered Noxafil oral suspension 400 mg twice daily with a high-fat meal. In this pooled analysis, the mean QTc (Fridericia) interval change from baseline was –5 msec following administration of the recommended clinical dose. A decrease in the QTc(F) interval (–3 msec) was also observed in a small number of subjects (n=16) administered placebo.
The placebo-adjusted mean maximum QTc(F) interval change from baseline was <0 msec (–8 msec). No healthy subject administered posaconazole had a QTc(F) interval ≥500 msec or an increase ≥60 msec in their QTc(F) interval from baseline. Posaconazole should be administered with caution to patients with potentially proarrhythmic conditions.
Do not administer with drugs that are known to prolong the QTc interval and are metabolized t… [Excerpted — this section continues on DailyMed.]

6.1CLINICAL TRIALS EXPERIENCE Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of posaconazole cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trial Experience with Posaconazole Delayed-Release Tablets for Prophylaxis of Invasive Aspergillus and Candida Infections The safety of posaconazole delayed-release tablets has been assessed in 230 patients in clinical trials.
Patients were enrolled in a non-comparative pharmacokinetic and safety trial of posaconazole delayed-release tablets when given as antifungal prophylaxis (Posaconazole Delayed-Release Tablet Study). Patients were immunocompromised with underlying conditions including hematological malignancy, neutropenia post-chemotherapy, GVHD, and post HSCT. This patient population was 62% male, had a mean age of 51 years (range 19 to 78 years, 17% of patients were ≥65 years of age), and were 93% White and 16% Hispanic.
Posaconazole delayed-release tablets were given for a median duration of 28 days. In this study, 20 adult patients received 200 mg daily dosage (this is not a recommended dosage [see Dosage and Administration (2.2) ] ) and 210 adult patients received 300 mg daily dosage (following twice daily dosing on Day 1 in each cohort). Table 9 presents adverse reactions (incidence of ≥10%) observed in patients treated with the posaconazole delayed-release tablets 300 mg daily dosage in the Posaconazole Delayed-Release Tablet Study.
The most frequently reported adverse reactions (>25%) in patients treated with posaconazole delayed-release tablets 300 mg once daily were diarrhea, pyrexia, and nausea. The most common adverse reaction leading to discontinuation of posaconazole delayed-release tablets 300 mg once daily was nausea (2%).

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Table 15 and Table 17 include drugs with clinically important drug interactions when administered concomitantly with posaconazole and Noxafil PowderMix and instructions for preventing or managing them. These recommendations are based on either drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious adverse reactions or loss of efficacy [see Clinical Pharmacology (12.3) ] . The following information was derived from data with Noxafil oral suspension or another posaconazole tablet formulation unless otherwise noted.
All clinically important drug interactions with Noxafil oral suspension, except for those that affect the absorption of posaconazole (via gastric pH and motility), are considered relevant to clinically important drug interactions with Noxafil injection, posaconazole delayed-release tablets, and Noxafil PowderMix for delayed-release oral suspension [ Clinical Pharmacology (12.3) ] . Consult the labeling of concomitantly used drugs to obtain further information about interactions with posaconazole. Interaction Drug Interaction Rifabutin, phenytoin, efavirenz, cimetidine, esomeprazole* Avoid co-administration unless the benefit outweighs the risks (7.1 , 7.2) Other drugs metabolized by CYP3A4 Consider dosage adjustment and monitor for adverse effects and toxicity (7.2) Digoxin Monitor digoxin plasma concentrations (7.2) Fosamprenavir, metoclopramide* Monitor for breakthrough fungal infections (7.1) *The drug interactions with esomeprazole and metoclopramide do not apply to posaconazole tablets (7.3 , 12.3 ).
7.1Effects of Other Drugs on Posaconazole and Noxafil PowderMix Posaconazole is primarily metabolized via UDP-glucuronosyltransferase and is a substrate of p-glycoprotein (P-gp) efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. Concomitant use of posaconazole with drugs that can decrease the plasma posaconazole concentrations should generally be avoided unless the benefit outweighs the risk.
If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections. Table 15: Drug Interactions Affecting Posaconazole and Noxafil PowderMix When Administered Concomitantly with Other Drugs UDP-Glucuronidase Inducers Mechanism and Clinical Effect(s) Posaconazole is a UDP-glucuronosyltransferase substrate. Concomitant use of posaconazole with UDP-glucuronidase inducers may decrease posaconazole exposure [see Clinical Pharmacology (12.3) ] , which may reduce the effectiveness of posaconazole.
Prevention or Management Efavirenz Avoid concomitant use of posaconazole with efavirenz, unless the benefit outweighs the risks. Rifabutin Avoid concomitant use of posaconazole with rifabutin unless the benefit to the patient outweighs the risk. If concomitant use is needed, monitor closely for breakthrough fungal infections.
See Table 17 for rifabutin monitoring considerations when posaconazole affects rifabutin via CYP3A4 inhibition. Phenytoin Avoid concomitant use of posaconazole with phenytoin unless the benefit to the patient outweighs the risk. If concomitant use is needed, monitor for breakthrough fungal infections.
See Table 17 for phenytoin monitoring considerations when posaconazole affects phenytoin via CYP3A4 inhibition. Fosamprenavir Mechanism and Clinical Effect(s) Concomitant use of posaconazole with fosamprenavir may lead to decreased posaconazole plasma concentrations [see Clinical Pharmacology (12.3) ] , which may reduce effectiveness of posaconazole. Prevention or Management If concomitant use of posaconazole with fosamprenavir is needed, monitor closely for breakthrough fungal infections.
7.2Effects of Posaconazole and Noxafil PowderMix on Other Drugs Posaconazole is a strong CYP3A4 inhibitor. Therefore, concomitant use of posaconazole may increase plasma concentrations of drugs that are CYP3A4 substrates [see Clinical Pharmacology (12.… [Excerpted — this section continues on DailyMed.]
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. (8.1) Pediatrics: Safety and effectiveness in patients younger than 2 years of age have not been established. (8.4) Severe Renal Impairment: Monitor closely for breakthrough fungal infections.
(8.6) Additional Pediatric Use information is approved for Merck Sharp & Dohme Corp.’s NOXAFIL (posaconazole) delayed-release tablets. However, due to Merck Sharp & Dohme Corp.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
8.1Pregnancy Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women. Available data for use of posaconazole in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, skeletal malformations were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers.
In pregnant rabbits dosed orally during organogenesis, doses of ≥ 3 times the clinical exposure caused an increase in resorptions (see Data ) . Based on animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is 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: Posaconazole resulted in maternal toxicity (reduced food consumption and reduced body weight gain) and skeletal malformations (cranial malformations and missing ribs) when given orally to pregnant rats during organogenesis (Gestational Days 6 through 15) at doses ≥27 mg/kg (≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of drug in healthy volunteers).
The no-effect dose for malformations and maternal toxicity in rats was 9 mg/kg, which is 0.7 times the exposure achieved with the 400 mg twice daily oral suspension regimen. No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions.
In rabbits dosed at 80 mg/kg, a reduction in body weight gain of females and a reduction in litter size were seen.
8.2Lactation Risk Summary There are no data on the presence of posaconazole in human milk, the effects on the breastfed infant, or the effects on milk production. Posaconazole is excreted in the milk of lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for posaconazole and any potential adverse effects on the breastfed child from posaconazole or from the underlying maternal condition.
8.4Pediatric Use The three posaconazole dosage forms (injection, delayed-release tablets, oral suspension) and one Noxafil PowderMix (for delayed-release oral suspension) dosage form are different products; are approved for different pediatric indications, age groups, and weights; have different dosing regimens; and have different preparation and administration instructions. Therefore, select the recommended dosage form based on the pediatric indication, age group, and weight [see Dosage and Administration (2.1) ] .

🤰 Pregnancy ▾
8.1Pregnancy Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women. Available data for use of posaconazole in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, skeletal malformations were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers.
In pregnant rabbits dosed orally during organogenesis, doses of ≥ 3 times the clinical exposure caused an increase in resorptions (see Data ) . Based on animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is 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: Posaconazole resulted in maternal toxicity (reduced food consumption and reduced body weight gain) and skeletal malformations (cranial malformations and missing ribs) when given orally to pregnant rats during organogenesis (Gestational Days 6 through 15) at doses ≥27 mg/kg (≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of drug in healthy volunteers).
The no-effect dose for malformations and maternal toxicity in rats was 9 mg/kg, which is 0.7 times the exposure achieved with the 400 mg twice daily oral suspension regimen. No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions.
In rabbits dosed at 80 mg/kg, a reduction in body weight gain of females and a reduction in litter size were seen.
🧒 Pediatric Use ▾
8.4Pediatric Use The three posaconazole dosage forms (injection, delayed-release tablets, oral suspension) and one Noxafil PowderMix (for delayed-release oral suspension) dosage form are different products; are approved for different pediatric indications, age groups, and weights; have different dosing regimens; and have different preparation and administration instructions. Therefore, select the recommended dosage form based on the pediatric indication, age group, and weight [see Dosage and Administration (2.1) ] .
Prophylaxis of Invasive Aspergillus and Candida Infections The safety and effectiveness of posaconazole delayed-release tablets have been established for the prophylaxis of invasive Aspergillus and Candida infections in pediatric patients 2 years of age and older who are at high risk of developing these infections due to being severely immunocompromised. Use of posaconazole for these pediatric indications is supported by adequate and well controlled studies of posaconazole in adults and pediatric patients aged 2 years of age and older and additional PK and safety data in pediatric patients 2 years of age and older [see Clinical Pharmacology (12.3) and Clinical studies (14) ] .
The safety and effectiveness of posaconazole have not been established in pediatric patients less than 2 years of age. Additional Pediatric Use information is approved for Merck Sharp & Dohme Corp.’s NOXAFIL (posaconazole) delayed-release tablets. However, due to Merck Sharp & Dohme Corp.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
🧓 Geriatric Use ▾
8.5Geriatric Use No overall differences in the safety or effectiveness of posaconazole delayed-release tablets have been observed between geriatric patients and younger adult patients in the clinical trials; therefore, the recommended dosage in geriatric patients is the same as that for younger adult patients. No clinically meaningful differences in posaconazole pharmacokinetics were observed in posaconazole-treated geriatric patients compared to posaconazole-treated younger adult patients during clinical trials [see Clinical Pharmacology (12.3) ] .
Of the 230 patients treated with posaconazole delayed-release tablets, 38 (17%) patients were >65 years of age.
🆘 Overdosage ▾
10 OVERDOSAGE There is no experience with overdosage of posaconazole delayed-release tablets. During the clinical trials, some patients received Noxafil oral suspension up to 1,600 mg/day with no adverse reactions noted that were different from the lower doses. In addition, accidental overdose was noted in one patient who took 1200 mg twice daily Noxafil oral suspension for 3 days.
No related adverse reactions were noted by the investigator. Posaconazole is not removed by hemodialysis.

12.2Pharmacodynamics Exposure Response Relationship: Prophylaxis of invasive Aspergillus and Candida Infections in Adults Who Are at High Risk of Developing These Infections Due to Being Severely Immunocompromised In clinical studies of neutropenic patients who were receiving cytotoxic chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndromes (MDS) or hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD), a wide range of plasma posaconazole exposures was noted following administration of Noxafil oral suspension.
A pharmacokinetic-pharmacodynamic analysis of patient data revealed an apparent association between average posaconazole concentrations (Cavg) and prophylactic efficacy (Table 18). A lower Cavg may be associated with an increased risk of treatment failure, defined as treatment discontinuation, use of empiric systemic antifungal therapy (SAF), or occurrence of breakthrough invasive fungal infections.

Posaconazole is highly bound to human plasma proteins (>98%), predominantly to albumin. Metabolism: Posaconazole primarily circulates as the parent compound in plasma. Of the circulating metabolites, the majority are glucuronide conjugates formed via UDP glucuronidation (phase 2 enzymes).
Posaconazole does not have any major circulating oxidative (CYP450 mediated) metabolites. The excreted metabolites in urine and feces account for ~17% of the administered radiolabeled dose. Posaconazole is a substrate for p-glycoprotein (P-gp) efflux.
In vitro studies with human hepatic microsomes and clinical studies indicate that posaconazole is an inhibitor primarily of CYP3A4. Excretion: Following administration of Noxafil oral suspension, posaconazole is predominantly eliminated in the feces (71% of the radiolabeled dose up to 120 hours) with the major component eliminated as parent drug (66% of the radiolabeled dose).

🧬 Pharmacodynamics ▾
12.2Pharmacodynamics Exposure Response Relationship: Prophylaxis of invasive Aspergillus and Candida Infections in Adults Who Are at High Risk of Developing These Infections Due to Being Severely Immunocompromised In clinical studies of neutropenic patients who were receiving cytotoxic chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndromes (MDS) or hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD), a wide range of plasma posaconazole exposures was noted following administration of Noxafil oral suspension.
A pharmacokinetic-pharmacodynamic analysis of patient data revealed an apparent association between average posaconazole concentrations (Cavg) and prophylactic efficacy (Table 18). A lower Cavg may be associated with an increased risk of treatment failure, defined as treatment discontinuation, use of empiric systemic antifungal therapy (SAF), or occurrence of breakthrough invasive fungal infections.

14 CLINICAL STUDIES
14.2Prophylaxis of Aspergillus and Candida Infections with Noxafil Oral Suspension Two randomized, controlled studies were conducted using posaconazole as prophylaxis for the prevention of invasive fungal infections (IFIs) among patients at high risk due to severely compromised immune systems. The first study (Noxafil Oral Suspension Study 1) was a randomized, double-blind trial that compared Noxafil oral suspension (200 mg three times a day) with fluconazole capsules (400 mg once daily) as prophylaxis against invasive fungal infections in allogeneic hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD).
Efficacy of prophylaxis was evaluated using a composite endpoint of proven/probable IFIs, death, or treatment with systemic antifungal therapy (patients may have met more than one of these criteria). This assessed all patients while on study therapy plus 7 days and at 16 weeks post-randomization. The mean duration of therapy was comparable between the 2 treatment groups (80 days, Noxafil oral suspension; 77 days, fluconazole).
Table 34 contains the results from Noxafil Oral Suspension Study 1.

These patients were considered failures. The second study (Noxafil Oral Suspension Study 2) was a randomized, open-label study that compared Noxafil oral suspension (200 mg 3 times a day) with fluconazole suspension (400 mg once daily) or itraconazole oral solution (200 mg twice a day) as prophylaxis against IFIs in neutropenic patients who were receiving cytotoxic chemotherapy for AML or MDS. As in Noxafil Oral Suspension Study 1, efficacy of prophylaxis was evaluated using a composite endpoint of proven/probable IFIs, death, or treatment with systemic antifungal therapy (Patients might have met more than one of these criteria).
This study assessed patients while on treatment plus 7 days and 100 days post-randomization. The mean duration of therapy was comparable between the 2 treatment groups (29 days, posaconazole; 25 days, fluconazole or itraconazole). Table 35 contains the results from Noxafil Oral Suspension Study 2.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis No drug-related neoplasms were recorded in rats or mice treated with posaconazole for 2 years at doses higher than the clinical dose. In a 2 year carcinogenicity study, rats were given posaconazole orally at doses up to 20 mg/kg (females), or 30 mg/kg (males). These doses are equivalent to 3.9- or 3.5 times the exposure achieved with a 400 mg twice daily oral suspension regimen, respectively, based on steady-state AUC in healthy volunteers administered a high-fat meal (400 mg twice daily oral suspension regimen).
In the mouse study, mice were treated at oral doses up to 60 mg/kg/day or 4.8 times the exposure achieved with a 400 mg twice daily oral suspension regimen. Mutagenesis Posaconazole was not genotoxic or clastogenic when evaluated in bacterial mutagenicity (Ames), a chromosome aberration study in human peripheral blood lymphocytes, a Chinese hamster ovary cell mutagenicity study, and a mouse bone marrow micronucleus study. Impairment of Fertility Posaconazole had no effect on fertility of male rats at a dose up to 180 mg/kg (1.7 x the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations in healthy volunteers) or female rats at a dose up to 45 mg/kg (2.2 x the 400 mg twice daily oral suspension regimen).
