2 DOSAGE AND ADMINISTRATION Noxafil 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 Noxafil 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 ) Noxafil injection must be administered through an in-line filter. ( 2.6 ) Administer Noxafil injection by intravenous infusion over approximately 90 minutes via a central venous line. ( 2.1 , 2.6 ) Do NOT administer Noxafil injection as an intravenous bolus injection. ( 2.1 ) Administer Noxafil delayed-release tablets with or without food. ( 2.1 ) Administer Noxafil oral suspension with a full meal. ( 2.1 ) Administer Noxafil PowderMix for delayed-release oral suspension with food. ( 2.1 ) Administer Noxafil PowderMix for delayed-release oral suspension with the provided notched tip syringes only. ( 2.1 ) See the full prescribing information for important administration instructions and preparation instructions for Noxafil (injection, delayed-release tablets, and oral suspension) and Noxafil PowderMix delayed-release oral suspension ( 2.5 , 2.6 , 2.7 , 2.8 , 2.9 , 2.10 ) For adult and pediatric patients aged 2 years of age and older, see the Full Prescribing Information for dosing recommendations for Noxafil injection, Noxafil delayed-release tablets, Noxafil oral suspension, and/or Noxafil PowderMix for delayed-release oral suspension based on the indication, age, and weight associated with the dosage form ( 1.1 , 1.2 , 1.3 , 2.1 , 2.2 , 2.3 , 2.4 ) 2.1 Important Administration Instructions Noxafil injection, Noxafil 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 Noxafil 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) ]. Noxafil injection Administer via a central venous line, including a central venous catheter or peripherally inserted central catheter (PICC), by slow intravenous infusion over approximately 90 minutes [see Dosage and Administration (2.6) ] . Do NOT administer Noxafil injection as an intravenous bolus injection. Noxafil 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, Noxafil delayed-release tablets should be used instead of Noxafil oral suspension for the prophylaxis indication. Noxafil delayed-release tablets generally provide higher plasma drug exposures than Noxafil oral suspension under both fed and fasted conditions [see Dosage and Administration (2.8) ] . Noxafil oral suspension Administer with a full meal or with a liquid nutritional supplement or an acidic carbonated beverage (e.g., ginger ale) in patients who cannot eat a full meal [see Dosage and Administration (2.8) ]. Noxafil PowderMix for delayed-release oral suspension Administer with food [see Clinical Pharmacology (12.3) ] . To ensure delivery of the correct dose, ONLY the provided notched tip syringes must be used for preparation and administration. The design of the notched tip syringe prevents aggregation of the suspension during preparation and administration [see Dosage and Administration (2.10) ] . 2.2 Recommended Dosage of Noxafil in Adult Patients The recommended dosage of Noxafil (injection, delayed-release tablets, and oral suspension) in adult patients for the treatment of invasive aspergillosis, prophylaxis of invasive Aspergillus and Candida infections in patients who are at high risk of developing these infections due to being severely immunocompromised, or for the treatment of oropharyngeal candidiasis (OPC) is shown in Table 1 [see Dosage and Administration (2.5 , 2.6 , 2.7 , 2.8 , 2.9) and Clinical Pharmacology (12.3) ].

To prepare the required dose, aseptically transfer one vial of Noxafil injection (containing 300 mg of posaconazole in 16.7 mL of solution) to an intravenous bag or bottle of one of the following compatible diluents to achieve a final posaconazole concentration between 1 mg/mL and 2 mg/mL: 0.45% Sodium Chloride Injection 0.9% Sodium Chloride Injection 5% Dextrose Injection 5% Dextrose and 0.45% Sodium Chloride Injection 5% Dextrose and 0.9% Sodium Chloride Injection 5% Dextrose and 20 mEq Potassium Chloride Injection Use of other diluents is not recommended because they may result in particulate formation. Discard any unused Noxafil injection from the vial. Parenteral drug products should be inspected visually for particulate matter prior to administration, whenever solution and container permit. Once admixed, the diluted Noxafil infusion solution ranges from colorless to yellow (variations of color within this range do not affect the quality of the product). Immediately use the diluted Noxafil infusion solution, once admixed. If not used immediately, refrigerate (2 to 8°C (36 to 46°F)) the diluted Noxafil infusion solution up to 24 hours. Discard any unused portion. Incompatible Diluents Co-administration of drug products besides the infusion solutions or products stated above are not recommended because this may result in particulate formation. The following diluents were determined to be incompatible with Noxafil injection; thus, do not dilute Noxafil injection with them: Lactated Ringer’s Injection Lactated Ringer's and 5% Dextrose Injection 4.2% Sodium Bicarbonate Injection 2.6 Administration of Diluted Noxafil Infusion Solution See Dosage and Administration (2.5) for the preparation instructions for the diluted Noxafil Solution. Important Administration Instructions for the Diluted Noxafil Infusion Solution Must administer diluted Noxafil Infusion Solution through a 0.22-micron polyethersulfone (PES) or polyvinylidene difluoride (PVDF) filter. Administer diluted Noxafil infusion solution via a central venous line, including a central venous catheter (CVC) or peripherally inserted central catheter (PICC), by slow intravenous infusion over approximately 90 minutes [see Adverse Reactions (6.1) ] . If a CVC or PICC are not available, may administer diluted Noxafil solution once through a peripheral venous catheter by intravenous infusion over approximately 30 minutes to bridge the period during which a CVC or PICC are replaced, inserted, or unavailable for use (e.g., the CVC is being used for intravenous treatment with another product). However, do not administer diluted Noxafil infusion solution more than once via peripheral venous catheter because in clinical trials, multiple peripheral infusions given through the same vein resulted in infusion site reactions [see Adverse Reactions (6.1) ]. When multiple dosing is required, the infusion should be done via a central venous line. Additional Administration Instructions for the Diluted Noxafil Infusion Solution Administer diluted Noxafil infusion solution intravenously through the same intravenous line (or cannula) with the following compatible infusion solutions: 0.45% Sodium Chloride Injection 0.9% Sodium Chloride Injection 5% Dextrose Injection 5% Dextrose and 0.45% Sodium Chloride Injection 5% Dextrose and 0.9% Sodium Chloride Injection 5% Dextrose and 20 mEq potassium chloride Injection Administer diluted Noxafil infusion solution intravenously at the same time through the same intravenous line (or cannula) with the following intravenous drug products prepared in 5% Dextrose Injection or 0.9% Sodium Chloride Injection: Amikacin Sulfate Injection Caspofungin Acetate for Injection Ciprofloxacin Injection Daptomycin for Injection Dobutamine Injection Famotidine Injection Filgrastim Injection Gentamicin Injection Hydromorphone Hydrochloride Injection Levofloxacin Injection Lorazepam Injection Meropenem for Injection Micafungin for Injection Morphine Sulfate Injection Norepinephrine Bitartrate Injection Potassium Chloride Injection Vancomycin Hydrochloride for Injection 2.7 Administration Instructions for Noxafil Delayed-Release Tablets Swallow the Noxafil delayed-release tablets whole. Do not divide, crush, or chew. Administer Noxafil delayed-release tablets orally with or without food [see Clinical Pharmacology (12.3) ]. 2.8 Administration Instructions for Noxafil Oral Suspension Administer Noxafil oral suspension with a full meal or with a liquid nutritional supplement or an acidic carbonated beverage (e.g., ginger ale) in patients who cannot eat a full meal. For patients who cannot eat a full meal, use Noxafil delayed-release tablets instead of the Noxafil oral suspension for the prophylaxis of invasive Aspergillus and Candida infections in those who are at high risk of developing these infections due to being severely immunocompromised. This is because Noxafil delayed-release tablets provide higher plasma drug exposures than Noxafil oral suspension under fasted condition [see Dosage and Administration (2.1) ]. For those patients using the Noxafil oral suspension: Shake Noxafil oral suspension well before use. Administer with measured dosing spoon provided in the package (see Figure 1 ). Figure 1: Measured dosing spoon provided in the package marked for doses of 2.5 mL and 5 mL. Administer each dose of Noxafil oral suspension during or immediately (i.e., within 20 minutes) following a full meal [see Clinical Pharmacology (12.3) ]. In patients who cannot eat a full meal and for whom Noxafil delayed-release tablets or Noxafil injection are not options, administer each dose of Noxafil oral suspension with a liquid nutritional supplement or an acidic carbonated beverage (e.g., ginger ale). If these patients cannot tolerate an oral nutritional supplement or an acidic carbonated beverage either use: An alternative antifungal therapy, or Noxafil oral suspension and closely monitor patients for breakthrough fungal infections. Rinse the spoon with water after each administration and before storage. Figure 1 2.9 Non-substitutability between Noxafil Oral Suspension and Other Formulations Noxafil oral suspension is not substitutable with Noxafil 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) ]. 2.10 Preparation and Administration Instructions for Noxafil PowderMix for Delayed-Release Oral Suspension For details on preparation and administration of Noxafil PowderMix for delayed-release oral suspension, see Instructions for Use . Preparation Instructions for Noxafil PowderMix for Delayed-Release Oral Suspension Do not open the Noxafil PowderMix packet until ready to prepare the drug. Remove cap from the mixing liquid and push the bottle adapter into the neck of the bottle. Once in place, the bottle adapter stays in the bottle. Remove 9 mL of mixing liquid using the provided blue syringe. Put the cap back on the bottle. Only use the mixing liquid in the kit to prepare Noxafil PowderMix. Using the provided mixing cup, combine 9 mL of mixing liquid and the entire contents of one packet in the Noxafil PowderMix kit and mix (containing 300 mg of posaconazole). Shake the mixing cup vigorously for 45 seconds to mix the powder and mixing liquid from the Noxafil PowderMix kit. The final concentration of the reconstituted Noxafil PowderMix delayed-release suspension is approximately 30 mg/mL of posaconazole. Check to make sure the powder is mixed (the mixture should look cloudy and free of clumps). Must use the reconstituted Noxafil PowderMix delayed-release suspension within 1 hour of reconstitution. Discard unused portion of the reconstituted Noxafil PowderMix delayed-release suspension. Administration Instructions for Noxafil PowderMix Delayed-Release Reconstituted Suspension To ensure delivery of the correct reconstituted Noxafil PowderMix Delayed-release dose, only use the provided notched tip syringes for preparation and administration because its design reduces the risk of aggregation of the product during preparation and administration. Choose the correct syringe based on the prescribed Noxafil PowderMix dose: Use 3 mL ( green ) notched tip syringe (provided with the kit) if dose is 3 mL or less. Use 10 mL ( blue ) notched tip syringe (provided with the kit) if dose is more than 3 mL. Administer reconstituted Noxafil PowderMix suspension orally with food within 1 hour of reconstitution [see Clinical Pharmacology (12.3) ]. The maximum dose that can be accurately withdrawn from the mixing cup after reconstitution is 240 mg (8 mL). Discarding Unused Reconstituted Noxafil PowderMix Suspension and Reuse of Syringes Not all the reconstituted Noxafil PowderMix suspension in the mixing cup will be used; there will be some left over in the mixing cup. Discard any remaining reconstituted Noxafil PowderMix suspension. The mixing cup may be hand washed and reused. Alternatively, the mixing cup may be discarded, and a similar mixing cup with a lid may be used for subsequent doses. The notched tip syringes may be hand washed and reused. 2.11 Dosage Modifications in Patients with Renal Impairment The recommended dosage of Noxafil oral suspension, Noxafil delayed-release tablets, and Noxafil PowderMix for delayed-release oral suspension is the same in patients with renal impairment compared to those with normal renal function. Avoid the use of Noxafil injection in patients with eGFR less than 50 mL/minute/1.73 m 2 , unless an assessment of the benefit/risk to the patient justifies its use. If the decision is made to use Noxafil injection in patients with eGFR less than 50 mL/minute/1.73 m 2 , closely monitor serum creatinine levels, and, if increases occur, consider changing to oral Noxafil therapy. The recommended dosage of Noxafil injection in patients with eGFR 50 to 90 mL/minute/1.73 m 2 is the same as those with normal renal function.

4 CONTRAINDICATIONS Known hypersensitivity to posaconazole or other azole antifungal agents. ( 4.1 ) Coadministration of Noxafil with the following drugs is contraindicated; Noxafil 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 ) Noxafil PowderMix for delayed-release oral suspension is contraindicated in patients with known or suspected Hereditary Fructose Intolerance (HFI). ( 4.7 , 5.9 , 8.4 ) 4.1 Hypersensitivity Noxafil is contraindicated in persons with known hypersensitivity to posaconazole or other azole antifungal agents. 4.2 Use with Sirolimus Noxafil is contraindicated with sirolimus. Concomitant administration of Noxafil 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) ] . 4.3 QT Prolongation with Concomitant Use with CYP3A4 Substrates Noxafil is contraindicated with CYP3A4 substrates that prolong the QT interval. Concomitant administration of Noxafil 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) ] . 4.4 HMG-CoA Reductase Inhibitors Primarily Metabolized Through CYP3A4 Coadministration 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) ] . 4.5 Use with Ergot Alkaloids Noxafil may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.2) ]. 4.6 Use with Venetoclax Coadministration of Noxafil 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) ]. 4.7 Use of Noxafil PowderMix for Delayed-Release Oral Suspension in Patients with Hereditary Fructose Intolerance Noxafil PowderMix for delayed-release oral suspension is contraindicated in patients with known or suspected hereditary fructose intolerance (HFI) [see Warnings and Precautions (5.9) and Use in Specific Populations (8.4) ] .

5 WARNINGS AND PRECAUTIONS Calcineurin-Inhibitor Toxicity : Noxafil increases concentrations of cyclosporine or tacrolimus; reduce dose of cyclosporine and tacrolimus and monitor concentrations frequently. ( 5.1 ) Arrhythmias and QTc Prolongation : Noxafil 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 Noxafil 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 ) Renal Impairment : Noxafil injection should be avoided in patients with moderate or severe renal impairment (eGFR less than 50 mL/min/1.73 m 2 ), unless an assessment of the benefit/risk to the patient justifies the use of Noxafil injection. ( 5.6 , 8.6 ) Concomitant Use with Midazolam : Noxafil 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 Noxafil, with vincristine has been associated with neurotoxicity and other serious adverse reactions; reserve azole antifungals, including Noxafil, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options. ( 5.8 , 7.2 ) Risk in Patients with Hereditary Fructose Intolerance (HFI) : Noxafil PowderMix for delayed-release oral suspension contains sorbitol. Risk of metabolic crisis with life-threatening hypoglycemia, hypophosphatemia, lactic acidosis, and hepatic failure. Obtain history of HFI symptoms in pediatric patients before Noxafil PowderMix for delayed-release oral suspension administration. ( 5.9 , 8.4 ) Breakthrough Fungal Infections : Monitor patients with severe diarrhea or vomiting when receiving Noxafil delayed-release tablets, Noxafil oral suspension, and Noxafil PowderMix for delayed-release oral suspension. ( 5.10 ) Venetoclax Toxicity: Concomitant administration of Noxafil 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 ) 5.1 Calcineurin-Inhibitor Toxicity Concomitant administration of Noxafil 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 Noxafil treatment and the tacrolimus or cyclosporine dose adjusted accordingly. 5.2 Arrhythmias and QT Prolongation Some azoles, including Noxafil, 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 Noxafil. 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 (18-85 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 Noxafil had a QTc(F) interval ≥500 msec or an increase ≥60 msec in their QTc(F) interval from baseline. Noxafil 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 through CYP3A4 [see Contraindications (4.3) and Drug Interactions (7.2) ] . 5.3 Electrolyte Disturbances Electrolyte disturbances, especially those involving potassium, magnesium or calcium levels, should be monitored and corrected as necessary before and during Noxafil therapy. 5.4 Pseudoaldosteronism Pseudoaldosteronism, manifested by the onset of hypertension or worsening of hypertension, and abnormal laboratory findings (hypokalemia, low serum renin and aldosterone, and elevated 11-deoxycortisol), has been reported with posaconazole use in the postmarket setting. Monitor blood pressure and potassium levels and manage as necessary. Management of pseudoaldosteronism may include discontinuation of Noxafil, substitution with an appropriate antifungal drug that is not associated with pseudoaldosteronism, or use of aldosterone receptor antagonists. 5.5 Hepatic Toxicity Hepatic reactions (e.g., mild to moderate elevations in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, and/or clinical hepatitis) have been reported in clinical trials. The elevations in liver tests were generally reversible on discontinuation of therapy, and in some instances these tests normalized without drug interruption. Cases of more severe hepatic reactions including cholestasis or hepatic failure including deaths have been reported in patients with serious underlying medical conditions (e.g., hematologic malignancy) during treatment with Noxafil. These severe hepatic reactions were seen primarily in subjects receiving the Noxafil oral suspension 800 mg daily (400 mg twice daily or 200 mg four times a day) in clinical trials. Liver tests should be evaluated at the start of and during the course of Noxafil therapy. Patients who develop abnormal liver tests during Noxafil therapy should be monitored for the development of more severe hepatic injury. Patient management should include laboratory evaluation of hepatic function (particularly liver tests and bilirubin). Discontinuation of Noxafil must be considered if clinical signs and symptoms consistent with liver disease develop that may be attributable to Noxafil. 5.6 Renal Impairment Due to the variability in exposure with Noxafil delayed-release tablets, Noxafil oral suspension, and Noxafil PowderMix for delayed-release oral suspension, patients with severe renal impairment should be monitored closely for breakthrough fungal infections [see Dosage and Administration (2.11) and Use in Specific Populations (8.6) ]. Noxafil injection should be avoided in patients with moderate or severe renal impairment (eGFR <50 mL/min/1.73 m 2 ), unless an assessment of the benefit/risk to the patient justifies the use of Noxafil injection. In patients with moderate or severe renal impairment (eGFR <50 mL/min/1.73 m 2 ), receiving the Noxafil injection, accumulation of the intravenous vehicle, SBECD, is expected to occur. Serum creatinine levels should be closely monitored in these patients, and, if increases occur, consideration should be given to changing to oral Noxafil therapy [see Dosage and Administration (2.11) and Use in Specific Populations (8.6) ] . 5.7 Midazolam Toxicity Concomitant administration of Noxafil with midazolam increases the midazolam plasma concentrations by approximately 5-fold. Increased plasma midazolam concentrations could potentiate and prolong hypnotic and sedative effects. Patients must be monitored closely for adverse effects associated with high plasma concentrations of midazolam and benzodiazepine receptor antagonists must be available to reverse these effects [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . 5.8 Vincristine Toxicity Concomitant administration of azole antifungals, including Noxafil, with vincristine has been associated with neurotoxicity and other serious adverse reactions, including seizures, peripheral neuropathy, syndrome of inappropriate antidiuretic hormone secretion, and paralytic ileus. Reserve azole antifungals, including Noxafil, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options [see Drug Interactions (7.2) ] . 5.9 Risk in Patients with Hereditary Fructose Intolerance (HFI) Noxafil PowderMix for delayed-release oral suspension contains sorbitol, an inactive ingredient, and may precipitate a metabolic crisis that may include, but is not limited to life-threatening hypoglycemia, hypophosphatemia, lactic acidosis, and hepatic failure in patients with HFI. Obtain careful history of HFI symptoms (nausea, vomiting, abdominal pain) with sorbitol/fructose/sucrose exposure prior to Noxafil PowderMix for delayed-release oral suspension administration because a diagnosis of HFI may not yet be established in pediatric patients [see Contraindications (4) and Use in Specific Populations (8.4) ] . 5.10 Breakthrough Fungal Infections Patients who have severe diarrhea or vomiting should be monitored closely for breakthrough fungal infections when receiving Noxafil delayed-release tablets, Noxafil oral suspension, or Noxafil PowderMix for delayed-release oral suspension. 5.11 Venetoclax Toxicity Concomitant administration of Noxafil, a strong CYP3A4 inhibitor, with venetoclax may increase venetoclax toxicities, including the risk of tumor lysis syndrome (TLS), neutropenia, and serious infections. In patients with CLL/SLL, administration of Noxafil during initiation and the ramp-up phase of venetoclax is contraindicated [see Contraindications (4.6) ] . Refer to the venetoclax labeling for safety monitoring and dose reduction in the steady daily dosing phase in CLL/SLL patients. For patients with acute myeloid leukemia (AML), dose reduction and safety monitoring are recommended across all dosing phases when coadministering Noxafil with venetoclax [see Drug Interactions (7.2) ]. Refer to the venetoclax prescribing information for dosing instructions.

7 DRUG INTERACTIONS Table 15 and Table 17 include drugs with clinically important drug interactions when administered concomitantly with Noxafil and Noxafil PowderMix and instructions for preventing or managing them. Table 16 includes important drug interactions specific to the absorption of posaconazole administered as either Noxafil oral suspension or Noxafil PowderMix. 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, Noxafil delayed-release tablets, and Noxafil PowderMix for delayed-release oral suspension [see 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 The drug interactions with esomeprazole and metoclopramide do not apply to Noxafil tablets or Noxafil PowderMix ( 7.3 , 12.3 ). Avoid coadministration 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 ) 7.1 Effects of Other Drugs on Noxafil 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 Noxafil 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 Noxafil 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 Noxafil 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 Noxafil 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. Table 16: Drug Interactions Affecting Noxafil Oral Suspension and Noxafil PowderMix Absorption When Administered Concomitantly with Other Drugs Noxafil Oral Suspension Cimetidine and Esomeprazole Mechanism and Clinical Effect(s) Concomitant use of Noxafil oral suspension with cimetidine or esomeprazole resulted in decreased posaconazole plasma concentrations [see Clinical Pharmacology (12.3) ], which may reduce effectiveness of Noxafil. Prevention or Management Avoid concomitant use of Noxafil oral suspension with cimetidine or esomeprazole unless the benefit outweighs the risks. If concomitant use is needed, monitor closely for breakthrough fungal infections. Metoclopramide Mechanism and Clinical Effect(s) Concomitant use of Noxafil oral suspension with metoclopramide decreased posaconazole plasma concentrations [see Clinical Pharmacology (12.3) ], which may reduce effectiveness of Noxafil oral suspension. Prevention or Management If Noxafil oral suspension is concomitantly administered with metoclopramide, closely monitor for breakthrough fungal infections. Noxafil Oral PowderMix Alcohol Mechanism and Clinical Effect(s) Posaconazole releases faster from Noxafil PowderMix in the presence of alcohol, which may interfere with Noxafil PowderMix’s delayed-release characteristics [see Clinical Pharmacology (12.3) ]. Prevention or Management Administration of Noxafil PowderMix with alcohol is not recommended. 7.2 Effects of Noxafil and Noxafil PowderMix on Other Drugs Posaconazole is a strong CYP3A4 inhibitor. Therefore, concomitant use of Noxafil may increase plasma concentrations of drugs that are CYP3A4 substrates [see Clinical Pharmacology (12.3) ] . Table 17: Drug Interactions Affecting Drugs Administered Concomitantly with Noxafil and Noxafil PowderMix Digoxin Clinical Effect(s) Increased digoxin plasma concentrations have been reported in patients who received concomitant posaconazole and digoxin. Prevention or Management Monitor digoxin plasma concentrations during concomitant use of posaconazole. Glipizide Clinical Effect(s) No dosage modification of glipizide is needed when used concomitantly with Noxafil. However, glucose concentrations decrease in some patients concomitantly administered posaconazole and glipizide. Prevention or Management Increase monitoring of glucose concentrations when used concomitantly. CYP3A Substrates Immunosuppressants that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole is a strong CYP3A4 inhibitor. Therefore, plasma concentrations of CYP3A4 substrates may be increased by posaconazole use [see Clinical Pharmacology (12.3) ]. Prevention or Management Sirolimus Posaconazole is contraindicated with sirolimus [see Clinical Pharmacology (12.3) ] . Tacrolimus • At initiation of posaconazole treatment, reduce the tacrolimus dosage to approximately one-third of the original tacrolimus dosage. • Frequent monitoring of tacrolimus whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus dosage should be modified accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] . Cyclosporine • At initiation of posaconazole treatment reduce the cyclosporine dosage to approximately three-fourths of the original dosage. • Frequent monitoring of cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the cyclosporine dosage should be modified accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] . CYP3A4 Substrates that Prolong QTc Interval Mechanism and Clinical Effect(s) Concomitant use of posaconazole with CYP3A4 substrates such as pimozide and quinidine may result in increased plasma concentrations of the CYP3A4 substrates leading to QTc interval prolongation and torsades de pointes [see Warnings and Precautions (5.2) ]. Prevention or Management Pimozide Concomitant use with posaconazole is contraindicated. Quinidine HMG-CoA Reductase Inhibitors (Statins) that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Concomitant use of posaconazole with simvastatin increased simvastatin plasma concentrations which can lead to rhabdomyolysis [see Clinical Pharmacology (12.3) ]. Prevention or Management Atorvastatin, Lovastatin, Simvastatin Concomitant use with posaconazole is contraindicated. Benzodiazepines that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Concomitant use of posaconazole with midazolam increased midazolam plasma concentrations which could potentiate and prolong hypnotic and sedative effects [see Clinical Pharmacology (12.3) ] . Prevention or Management Midazolam, Alprazolam, Triazolam Closely monitor for adverse reactions associated with high plasma concentrations of benzodiazepines that are CYP3A4 substrates during concomitant use, and a benzodiazepine receptor antagonist should be available to reverse effects [see Warnings and Precautions (5.7) ]. Calcium Channel Blockers that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole may increase the plasma concentrations of calcium channel blockers that are substrates of CYP3A4. Prevention or Management Verapamil, Diltiazem, Nifedipine, Nicardipine, Felodipine Monitor frequently for adverse reactions and toxicity with concomitant use of posaconazole with calcium channel blockers that are CYP3A4 substrates. Dosage reduction of the calcium channel blocker may be needed. Anti-HIV Drugs that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Ritonavir and atazanavir are CYP3A4 substrates and posaconazole increased plasma concentrations of these drugs [see Clinical Pharmacology (12.3) ]. Prevention or Management Ritonavir and Atazanavir Monitor frequently for adverse reactions and toxicity of ritonavir and atazanavir during concomitant use. Antineoplastic Drugs that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole may increase plasma concentrations of oncology drugs that are CYP3A4 substrates, which may increase the risk of serious adverse reactions. Prevention or Management Venetoclax CLL/SLL patients : Concomitant use of posaconazole with venetoclax during initiation and ramp-up phase is contraindicated. AML patients : With concomitant use, venetoclax dosage reduction and safety monitoring is recommended across all dosing phases [see Warnings and Precautions (5.11) ] . Vinca alkaloids (e.g., vincristine, vinblastine) Reserve concomitant use for patients with no alternative antifungal treatment options [see Warnings and Precautions (5.8) ]. Ergot Alkaloids Mechanism and Clinical Effect(s) Most of the ergot alkaloids are CYP3A4 substrates. Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism. Prevention or Management Ergotamine, Dihydroergotamine Concomitant use with posaconazole is contraindicated. Phenytoin Mechanism and Clinical Effect(s) Phenytoin is a CYP3A4 substrate. Concomitant use of posaconazole with phenytoin increased phenytoin plasma concentrations [see Clinical Pharmacology (12.3) ]. Prevention or Management Avoid concomitant use of posaconazole with phenytoin unless the benefit outweighs the risk. frequently monitor phenytoin concentrations and consider a dosage reduction of phenytoin. See Table 15 for additional monitoring considerations when phenytoin affects posaconazole via UDP-glucuronosyltransferase inhibition. Rifabutin Mechanism and Clinical Effect(s) Rifabutin is a CYP3A4 substrate. Concomitant use of posaconazole with rifabutin increased rifabutin plasma concentrations [see Clinical Pharmacology (12.3) ]. Prevention or Management Avoid concomitant use of posaconazole with rifabutin unless the benefit outweighs the risk. Frequent monitoring of full blood counts and adverse reactions due to increased rifabutin plasma concentrations (e.g., uveitis, leukopenia) during concomitant use are recommended. See Table 15 for additional monitoring considerations when rifabutin affects posaconazole via UDP-glucuronosyltransferase inhibition. 7.3 Absence of Clinically Important Interaction with Noxafil and Noxafil PowderMix Additional clinical studies demonstrated that no clinically important effects on zidovudine, lamivudine, indinavir, or caffeine were observed when administered with Noxafil 200 mg once daily; therefore, no dose adjustments are required for these drugs when coadministered with Noxafil 200 mg once daily. No clinically relevant effects on the pharmacokinetics of Noxafil delayed-release tablets were observed during concomitant use with antacids, H 2 -receptor antagonists and proton pump inhibitors, and metoclopramide [see Clinical Pharmacology (12.3) ] . No dosage adjustment of Noxafil delayed-release tablets or Noxafil PowderMix for delayed-release oral suspension is required during concomitant use with these drugs. No clinically relevant effects on the pharmacokinetics of Noxafil oral suspension were observed during concomitant use with antacids, H 2 -receptor antagonists (other than cimetidine), and loperamide [see Clinical Pharmacology (12.3) ] . No dosage adjustment of Noxafil oral suspension is required during concomitant use with these drugs (other than cimetidine).

6 ADVERSE REACTIONS The following serious and otherwise important adverse reactions are discussed in detail in another section of the labeling: Arrhythmias and QT Prolongation [see Warnings and Precautions (5.2) ] Electrolyte Disturbances [see Warnings and Precautions (5.3) ] Pseudoaldosteronism [see Warnings and Precautions (5.4) ] Hepatic Toxicity [see Warnings and Precautions (5.5) ] Adult Patients: Common adverse reactions in studies with Noxafil in adults are diarrhea, nausea, fever, vomiting, headache, coughing, and hypokalemia. ( 6.1 ) Pediatric Patients: Common adverse reactions (incidence >20% receiving 6 mg/kg Noxafil injection and Noxafil PowderMix for delayed-release oral suspension) in a study in pediatric patients are pyrexia, febrile neutropenia, vomiting, mucosal inflammation, pruritus, hypertension, hypokalemia, and stomatitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme LLC at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of Noxafil cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Treatment of Invasive Aspergillosis in Adults and Adolescents (Noxafil injection and Noxafil Delayed-Release Tablets) The safety of Noxafil injection and Noxafil delayed-release tablets was assessed in a randomized, double-blind, active-controlled clinical study of Noxafil injection and Noxafil delayed-release tablets versus voriconazole for treatment of invasive aspergillosis (Aspergillosis Treatment Study). A total of 575 adult and pediatric patients 14 years of age and older (288 in the Noxafil group, 287 in voriconazole group (voriconazole for injection or voriconazole tablets)) with proven, probable or possible invasive aspergillosis were included. The median duration of treatment was 67 days for Noxafil injection or Noxafil delayed-release tablets and 64 days for voriconazole. In this study, 55% to 60% of patients started intravenous treatment with Noxafil (Noxafil injection) or voriconazole (voriconazole for injection). The median duration of the first instance of intravenous treatment (before switching to oral treatment or discontinuing or completing study treatment) was 9 days for both groups. Table 7 presents adverse reactions reported at an incidence of ≥10% in either one of the treatment groups in the Aspergillosis Treatment Study. Adverse reactions leading to treatment discontinuation were reported for 34% of patients. The most commonly reported adverse reactions (>2% of patients) leading to treatment discontinuation were septic shock, respiratory failure, and bronchopulmonary aspergillosis in the Noxafil group, and septic shock and acute myeloid leukemia in the voriconazole group. The most frequently reported adverse reactions in the Noxafil-treated group were pyrexia (28%), hypokalemia (28%), and nausea (23%).

Therefore, in subsequent studies, Noxafil injection was administered via central venous catheter [see Dosage and Administration (2.6) ]. The safety of Noxafil injection has been assessed in 268 patients in a clinical trial. Patients were enrolled in a non-comparative pharmacokinetic and safety trial of Noxafil injection when given as antifungal prophylaxis (Noxafil Injection Study). Patients were immunocompromised with underlying conditions including hematological malignancy, neutropenia post-chemotherapy, GVHD, and post HSCT. This patient population was 55% male, had a mean age of 51 years (range: 18-82 years, 19% of patients were ≥65 years of age), and were 95% White and 8% Hispanic. In this study, 10 patients received a single dose of 200 mg Noxafil injection, 21 patients received 200 mg daily dosage for a median of 14 days, and 237 patients received 300 mg daily dosage for a median of 9 days (the 200 mg dosage is not a recommended dosage for prophylaxis of invasive Aspergillus and Candida infections in adults [see Dosage and Administration (2.2) ]. In the 300 mg daily dosage group each patient received a loading intravenous dose of Noxafil injection 300 mg twice on Day 1, then intravenous Noxafil injection therapy, and finally Noxafil oral suspension to complete 28 days of total Noxafil therapy. Table 8 presents adverse reactions observed in patients treated with the Noxafil injection 300 mg daily dosage group in the Noxafil Injection Study. The most frequently reported adverse reactions with an onset during the intravenous Noxafil injection phase of dosing with 300 mg once daily were diarrhea (32%), hypokalemia (22%), pyrexia (21%), and nausea (19%). These adverse reactions were consistent with those seen in studies with Noxafil oral suspension. Table 8: Adverse Reactions in at least 10% of Adults Receiving Noxafil Injection for the Prophylaxis of Invasive Aspergillus and Candida infections Adverse Reactions Noxafil Injection Treatment Phase n=237 Adverse reactions reported in patients with an onset during the Noxafil intravenous dosing phase of the study.

Patients were enrolled in a non-comparative pharmacokinetic and safety trial of Noxafil delayed-release tablets when given as antifungal prophylaxis (Noxafil 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: 19-78 years, 17% of patients were ≥65 years of age), and were 93% White and 16% Hispanic. Noxafil 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 Noxafil delayed-release tablets 300 mg daily dosage in the Noxafil Delayed-Release Tablet Study. The most frequently reported adverse reactions (>25%) in patients treated with Noxafil delayed-release tablets 300 mg once daily were diarrhea, pyrexia, and nausea. The most common adverse reaction leading to discontinuation of Noxafil delayed-release tablets 300 mg once daily was nausea (2%).

This patient population was 71% male, had a mean age of 42 years (range: 8-84 years, 6% of patients were ≥65 years of age and 1% was <18 years of age), and were 64% White, 14% Black, 16% Hispanic. Noxafil oral suspension therapy was given to 171 patients for ≥6 months, including 58 patients who received Noxafil oral suspension therapy for ≥12 months. Table 10 presents adverse reactions observed at an incidence of >10% in the studies for prophylaxis of invasive Aspergillus and Candida infections. Table 11 presents adverse reactions observed at an incidence of at least 10% in the OPC/rOPC studies. Prophylaxis of Invasive Aspergillus and Candida Infections (Noxafil oral suspension) In the two randomized, comparative studies for prophylaxis of invasive Aspergillus and Candida infections in those at high risk of developing these infections due to being severely immunocompromised (Noxafil Oral Suspension Study 1 and 2), the safety of Noxafil oral suspension 200 mg three times a day was compared to fluconazole 400 mg once daily or itraconazole 200 mg twice a day in severely immunocompromised patients. The most frequently reported adverse reactions (>30%) in these trials were fever, diarrhea, and nausea. The most common adverse reactions leading to discontinuation of Noxafil oral suspension were GI adverse reactions, specifically, nausea (2%), vomiting (2%), and increased hepatic enzymes (2%).

An additional 239 HIV-infected patients with refractory OPC (rOPC) received Noxafil oral suspension in two non-comparative trials for rOPC. Of these patients, 149 received the 800 mg/day dosage and the remainder received the less than or equal to 400 mg once daily dosage. In the nonrefractory OPC and rOPC studies, the most common adverse reactions in patients treated with Noxafil oral suspension were fever, diarrhea, nausea, headache, vomiting, and coughing. Adverse reactions were reported more frequently in the studies of patients with refractory OPC. Among these highly immunocompromised patients with advanced HIV disease, serious adverse reactions were reported in 55% (132/239) of Noxafil oral suspension-treated patients.

Clinical Trials in Pediatric Patients 2 Years of Age and Older The safety of Noxafil injection and Noxafil PowderMix (for delayed-release oral suspension) for prophylaxis of invasive fungal infections was evaluated in an open-label uncontrolled dose-ranging pharmacokinetic and safety study of Noxafil injection and Noxafil PowderMix (Pediatric Study 1, NCT02452034). In this study, 115 immunocompromised pediatric patients 2 to less than 18 years of age with known or expected neutropenia initially received Noxafil injection (up to 6 mg/kg twice daily for the first day and then up to 6 mg/kg for at least 7 days), and then 63 patients were transitioned to Noxafil PowderMix (up to 6 mg/kg once daily). The mean overall treatment duration was 21 days including a mean duration of 14 days (range: 1 to 28 days) on Noxafil injection and a mean duration of 12 days (range: 2 to 18 days) on Noxafil PowderMix [see Clinical Pharmacology (12.3) ]. In this study, the reported adverse reaction profile of Noxafil injection and Noxafil PowderMix in pediatric patients was consistent with the safety profile of Noxafil in adults. The most common adverse reactions that occurred in greater than 20% of pediatric patients who received Noxafil injection and Noxafil PowderMix were pyrexia, febrile neutropenia, vomiting, mucosal inflammation, pruritus, hypertension, hypokalemia, and stomatitis. The safety of Noxafil injection, Noxafil delayed-release tablets, and Noxafil PowderMix for delayed-release oral suspension for the treatment of invasive aspergillosis was evaluated in an open-label, non-comparative clinical study in 31 pediatric patients 2 to less than 18 years of age with a diagnosis of possible, probable, or proven invasive aspergillosis (Pediatric Study 2, NCT04218851). In this study, all 31 pediatric patients initially received Noxafil injection (6 mg/kg twice daily on the first day and then 6 mg/kg once daily) for the treatment of invasive aspergillosis; 12 patients were transitioned to Noxafil delayed-release tablets (300 mg once daily) if they weighed ≥40 kg, and 10 patients were transitioned to Noxafil PowderMix (based on weight) if they weighed 10 to 40 kg [see Dosage and Administration (2.3) ] . The mean overall treatment duration was 50 days including 15 days (range: 2 to 78 days) on Noxafil injection, 54 days (range: 6 to 80 days) on Noxafil delayed-release tablets, and 44 days (range: 7 to 76 days) on Noxafil PowderMix. The reported adverse reaction profile of Noxafil injection, Noxafil delayed-release tablets, and Noxafil PowderMix in pediatric patients was consistent with the known safety profile of Noxafil in adults. The most common adverse reactions that occurred in greater than 20% of pediatric patients who received any of the three formulations of Noxafil were vomiting, pyrexia, abdominal pain, liver test abnormalities, and hypertension. 6.2 Postmarketing Experience The following adverse reaction has been identified during the post-approval use of Noxafil. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

8.1 Pregnancy Risk Summary Based on findings from animal data, Noxafil may cause fetal harm when administered to pregnant women. Available data for use of Noxafil 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 Noxafil 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.
