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.

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%).

10 9 12 Treatment of Nonrefractory OPC and Refractory OPC (Noxafil oral suspension) In two randomized comparative studies for the treatment of nonrefractory OPC, the safety of Noxafil oral suspension (less than or equal to 400 mg once daily) in 557 HIV-infected patients was compared to the safety of fluconazole (100 mg once daily) in 262 HIV-infected patients.
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.
The most commonly reported serious adverse reactions were fever (13%) and neutropenia (10%).

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.
Endocrine Disorders: Pseudoaldosteronism
( 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.

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.

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%).

10 9 12 Treatment of Nonrefractory OPC and Refractory OPC (Noxafil oral suspension) In two randomized comparative studies for the treatment of nonrefractory OPC, the safety of Noxafil oral suspension (less than or equal to 400 mg once daily) in 557 HIV-infected patients was compared to the safety of fluconazole (100 mg once daily) in 262 HIV-infected patients.
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.
The most commonly reported serious adverse reactions were fever (13%) and neutropenia (10%).

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.
