6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions occurring in ≥2% of patients include nausea, vomiting, diarrhea, headache, decreased appetite, dizziness, abdominal pain, pruritus, somnolence, elevated transaminases, and elevated creatinine (6.1). To report SUSPECTED ADVERSE REACTIONS, contact Profounda, Inc. at 1-866-588-5405 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Visceral Leishmaniasis One Phase 3 trial was conducted in patients ≥ 12 years of age in India. Two-hundred and ninety-nine (299) patients (211 men and 88 women) received oral IMPAVIDO at a target dose of 2.5 mg/kg/day for 28 days (50 mg capsule once daily if weight was less than 25 kg and 50 mg capsule twice daily if weight was 25 kg or greater). Patients ranged between 12 and 64 years of age.
Weight ranged between 15 and 67 kg (mean weight 38.6 kg) and BMI ranged between 8.2 and 24 (mean 16.1). Ninety-nine (99) patients received 1 mg/kg/day amphotericin B deoxycholate intravenously every other day for 15 doses. A statistically significant higher percentage of men received IMPAVIDO compared to amphotericin B.
Less than 1% of patients who received IMPAVIDO died (2/299) and no patient who received amphotericin B died. Serious adverse reactions were reported in 2% of IMPAVIDO recipients (6/299) and 1% of amphotericin B recipients (1/99). Approximately 3% of patients discontinued treatment in each treatment arm due to an adverse reaction.
Serious adverse reactions and adverse reactions leading to drug discontinuation that were thought to be related or possibly related to IMPAVIDO included Stevens-Johnson syndrome, melena and thrombocytopenia, arthritis and skin rash, CTCAE Common Terminology Criteria for Adverse Events Grade 4 diarrhea (≥10 stools per day) and CTCAE Grade 4 hyperbilirubinemia (≥10x upper limit of normal ULN). Table 2: Treatment Emergent Adverse Reactions Occurring in ≥2% of Visceral Leishmaniasis Patients Receiving IMPAVIDO System Organ Class Preferred Term IMPAVIDO N = 299 Amphotericin B Deoxycholate N = 99 Gastrointestinal Disorders Diarrhea 61 (20.4%) 6 (6.1%) Vomiting 113 (37.8%) 20 (20.0%) General Disorders Asthenia 19 (6.3%) 4 (4.0%) Metabolism and Nutrition Disorders Decreased Appetite 69 (23.1%) 22 (22.2%) In this study, creatinine (Cr) elevations ≥ 1.5 times above baseline occurred in approximately 10% of IMPAVIDO recipients and in 40% of amphotericin B recipients at the end of therapy.
Ten percent of subjects in each arm had Cr elevations ≥1.5 times above baseline at 6 months follow up. No IMPAVIDO recipient discontinued therapy due to Cr elevation. Elevations of transaminases during therapy occurred in up to half of IMPAVIDO recipients and up to a third of amphotericin B recipients.
The elevations were mild (< 3x ULN) or moderate (3-5x ULN) in 94% and 6% respectively of IMPAVIDO-treated patients who experienced an elevation. No patient discontinued therapy due to elevations in transaminases. At the end of therapy, 62% and 2.4% of IMPAVIDO recipients and 54% and 2% of amphotericin B recipients had platelet count < 150,000 and < 50,000 respectively.
Cutaneous Leishmaniasis The efficacy of IMPAVIDO in the treatment of cutaneous leishmaniasis was evaluated in one placebo-controlled trial conducted in Colombia and Guatemala and in two comparative trials conducted in Bolivia and Brazil respectively. In the placebo-controlled trial, eighty-nine (89) patients ≥12 years of age received a target IMPAVIDO dose of 2.5 mg/kg/day for 28 days and forty-four (44) received placebo. In the comparative trials, one hundred and twenty (120) patients ≥12 years of age received a target IMPAVIDO dose of 2.5 mg/kg/day for 28 days and fifty eight (58) patients received 20 mg/kg/…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS In vitro and animal metabolism studies showed that miltefosine did not markedly induce or inhibit the activity of the major human cytochrome P450 enzymes [see Clinical Pharmacology ( 12.3 )] . The potential of miltefosine to interact with drug transporters has not been evaluated. IMPAVIDO did not inhibit human cytochrome P450 enzymes in vitro. IMPAVIDO did not induce cytochrome 3A activity in rats( 7 , 12.3 ).
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: IMPAVIDO should not be used during pregnancy. Obtain a urine or serum pregnancy test in females of reproductive potential prior to prescribing ( 4.1 , 5.1 , 8.1 , 8.8 , 13.1 ). Nursing Mothers: Discontinue drug or nursing depending on importance of drug to mother.
Avoid breastfeeding for 5 months after IMPAVIDO therapy ( 8.3 ). Females and Males of Reproductive Potential: Advise females to use effective contraception during therapy and for 5 months after therapy. Advise patients of reproductive toxicities in animals, and that the potential for impaired fertility in humans has not been adequately evaluated ( 5.1 , 5.2 , 8.8 ).
8.1Pregnancy Pregnancy Category D Risk Summary IMPAVIDO may cause fetal harm. Human pregnancy data are not available, however, embryo-fetal toxicity including death and teratogenicity, was observed in embryo-fetal studies in rats and rabbits administered oral miltefosine during organogenesis at doses that were respectively 0.06 and 0.2 times the maximum recommended human dose (MRHD), based on body surface area (BSA) comparison. Numerous visceral and skeletal fetal malformations were observed in a fertility study in female rats administered miltefosine prior to mating through day 7 of pregnancy at doses 0.3 times the MRHD.
Do not administer IMPAVIDO to pregnant women. Clinical Considerations During pregnancy, visceral leishmaniasis may be life-threatening for the mother and may result in adverse fetal outcomes, including spontaneous abortion, congenital disease due to vertical transmission, small for gestational age newborn, and severe anemia. During pregnancy, cutaneous leishmaniasis may manifest with larger and atypical appearing lesions and may be associated with increased risk for adverse fetal outcomes, including preterm births and stillbirths.
Animal Data Miltefosine administration in rat embryo-fetal toxicity studies during early embryonic development (Day 6 to Day 15 of gestation) caused embryo-fetal toxicity including death and teratogenicity at dosages of ≥ 1.2 mg/kg/day (0.06 times the MRHD based on BSA comparison). Teratogenic effects included undeveloped cerebrum, hemorrhagic fluid filling the lumina of the skull, cleft palate and generalized edema. Embryo-fetal toxicity was also observed in rabbits after oral administration of miltefosine during organogenesis (Day 6 to Day 18 of gestation) at doses ≥ 2.4 mg/kg/day (0.2 times the MRHD based on BSA comparison).
In both rats and rabbits, there were no viable litters at miltefosine doses ≥ 6.0 mg/kg/day (0.3 or 0.6 times the MRHD based on BSA comparisons for rats and rabbits respectively). In a separate female fertility study in rats, miltefosine doses ≥ 6.81 mg/kg/day (0.3 times the MRHD based on BSA comparison) administered for four weeks before mating and up to Day 7 of pregnancy produced numerous visceral (misshapen cerebral structures, dilated ventricles filled with brown masses, misshapen spinal cord, misshapen and malpositioned eyes, hypophysis, and absent inner ear) and skeletal (cleft palate, dumbbell-shaped ossification of thoracic vertebral centers, markedly enlarged skull bones, and markedly dilated suturae) fetal malformations. [see Contraindications ( 4.1 ), Nonclinical Toxicology ( 13.1 )] .
8.3Nursing Mothers It is not known whether IMPAVIDO is present in human milk. Because many drugs are present in human milk and because of the potential for serious adverse reactions in nursing infants from IMPAVIDO, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Breastfeeding should be avoided for 5 months after IMPAVIDO therapy.
8.4Pediatric Use Safety and effectiveness in pediatric patients < 12 years have not been established. Juvenile rats were more sensitive to the miltefosine-induced effects, especially retinal and kidney effects, than adult rats [see Indications and Usage ( 1 )] .

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness in pediatric patients < 12 years have not been established. Juvenile rats were more sensitive to the miltefosine-induced effects, especially retinal and kidney effects, than adult rats [see Indications and Usage ( 1 )] .
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of IMPAVIDO did not include sufficient numbers of subjects 65 years of age and over to determine if they respond differently than younger subjects.
🆘 Overdosage ▾
10 OVERDOSAGE The common adverse effects of vomiting, diarrhea, and abdominal pain are likely in case of overdose. Institute adequate hydration to prevent the risk of impaired renal function, and replace electrolytes as necessary. Because miltefosine is only slightly excreted in the urine, forced diuresis will not increase miltefosine excretion. Gastrointestinal lavage is of unknown value. A specific antidote to treat miltefosine overdose is not known.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Miltefosine is an anti-leishmanial agent [see Clinical Pharmacology ( 12.4 )] .
12.3Pharmacokinetics The pharmacokinetic parameters of miltefosine in patients with visceral and cutaneous leishmaniasis treated for 28 days with IMPAVIDO are listed in Table 5. Due to the long half-life of miltefosine (> 6 days), trough plasma concentrations did not appear to reach a steady state at the end of treatment (i.e., Day 28). Table 5: Mean (%CV) Pharmacokinetic Parameters for Miltefosine Following Oral Capsule Administration to Adult Patients with Visceral and Cutaneous Leishmaniasis a: Adolescent (≥12 years)/Adults, mean dose per kg was 3.1 mg/kg/day b: Adolescent (≥12 years)/Adults, mean dose per kg was 3.6 mg/kg/day c: Adults, mean dose per kg was 1.8 mg/kg/day d: median (range) e: AUC 0-12h for BID, AUC 0-8h for TID f: t 1/2, α = distribution phase half-life; t 1/2,β = terminal elimination phase half-life g: Estimates based on a population PK model h: mean (% standard error) Dose C max (µg/mL) T max d (hr) AUC tau e (µg∙hr/mL) t 1/2,α f (day) t 1/2,β g (day) Visceral Leishmaniasis (on Day 23) 50 mg BID (4 wks) a 66.2 (28.5) 7(2-12) 636 (26.7) 6.4 (31.1) 50 mg BID (1 wk)/ 50 mg TID (3 wks) b 75.9 (17.6) 4 (2-8) 486 (18.1) 8.5 (28.9) Cutaneous Leishmaniasis c (on Day 27) 50 mg TID (4 wks) 37.3 (22) f 295 (22) f 6.8 (5.8) g,h 30.7 (18.3) g,h Absorption Absolute bioavailability of miltefosine has not been determined.
In patients with visceral leishmaniasis, maximum miltefosine concentrations following oral administration of IMPAVIDO capsules were reached right before the next dose in many patients, indicating that the absorption of miltefosine may proceed throughout the dosing interval. Distribution The distribution of miltefosine has not been studied in humans. Human plasma protein binding of miltefosine, evaluated by an ultracentrifugation method, was 98% over the drug concentration range from 0.1 to 10 µg/mL.
In rats, radioactivity of [ 14 C] miltefosine is widely distributed after both single and repeated oral administration with highest uptake of radioactivity in kidney, liver, and spleen. Placental transfer and excretion into milk have not been investigated. Metabolism and Excretion No in vitro oxidative metabolism by 15 different human cytochrome P450 enzymes (1A1, 1A2, 1B1, 2A6, 2B6, 2C8, 2C9, 2C18, 2C19, 2D6, 2E1, 3A4, 3A5, 3A7, and 4A1) was observed.
A slow metabolic breakdown could be shown in human hepatocytes, resulting in the release of choline by phospholipase D-like cleavage of the miltefosine molecule. The fatty alcohol-containing fragment of miltefosine can enter the metabolism of fatty acids after being oxidized to palmitic acid. This oxidation is blocked in patients with Sjögren-Larsson syndrome, which is caused by a genetic defect in fatty aldehyde dehydrogenase activity.
IMPAVIDO is contraindicated in patients who have Sjögren-Larsson-Syndrome [see Contraindications ( 4.2 )] . There was little or no evidence of time or metabolism dependent inhibition of the cytochrome P450 enzymes examined at up to approximately 40 µg/mL miltefosine. Oral administration of miltefosine did not markedly induce the content of hepatic CYP3A assayed by demethylation activity of erythromycin in rats.
In visceral leishmaniasis patients, <0.2% of the administered dose was excreted into the urine.
12.4Microbiology Mechanism of Action The specific mode of action of miltefosine against Leishmania species is unknown. The mechanism of action of miltefosine is likely to involve interaction with lipids (phospholipids and sterols), including membrane lipids, inhibition of cytochrome c oxidase (mitochondrial function), and apoptosis-like cell death. Activity In Vitro and In Vivo Miltefosine has anti-leishmanial activity in vitro and in clinical infections [see Clinical Studies ( 14 )] .
