Overview

Artemether and lumefantrin is an antimanlaric that is FDA approved for the treatment of acute, uncomplicated malaria infections due to Plasmodium falciparum in patients of 5 kg bodyweight and above. Common adverse reactions include headache, anorexia, dizziness, asthenia, arthralgia and myalgia.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Administration Instructions

  • Coartem Tablets should be taken with food. Patients with acute malaria are frequently averse to food. Patients should be encouraged to resume normal eating as soon as food can be tolerated since this improves absorption of artemether and lumefantrine.
  • For patients who are unable to swallow the tablets such as infants and children, Coartem Tablets may be crushed and mixed with a small amount of water (one to two teaspoons) in a clean container for administration immediately prior to use. The container can be rinsed with more water and the contents swallowed by the patient. The crushed tablet preparation should be followed whenever possible by food/drink (e.g., milk, formula, pudding, broth, and porridge).
  • In the event of vomiting within 1 to 2 hours of administration, a repeat dose should be taken. If the repeat dose is vomited, the patient should be given an alternative antimalarial for treatment.

Dosage in Adult Patients (>16 years of age)

  • A 3-day treatment schedule with a total of 6 doses is recommended for adult patients with a bodyweight of 35 kg and above:
  • Four tablets as a single initial dose, 4 tablets again after 8 hours and then 4 tablets twice daily (morning and evening) for the following two days (total course of 24 tablets).
  • For patients weighing less than 35 kg, see Dosage in Pediatric Patients.

Dosage in Pediatric Patients

A 3-day treatment schedule with a total of 6 doses is recommended as below:

  • 5 kg to less than 15 kg bodyweight: One tablet as an initial dose, 1 tablet again after 8 hours and then 1 tablet twice daily (morning and evening) for the following two days (total course of 6 tablets).
  • 15 kg to less than 25 kg bodyweight: Two tablets as an initial dose, 2 tablets again after 8 hours and then 2 tablets twice daily (morning and evening) for the following two days (total course of 12 tablets).
  • 25 kg to less than 35 kg bodyweight: Three tablets as an initial dose, 3 tablets again after 8 hours and then 3 tablets twice daily (morning and evening) for the following two days (total course of 18 tablets).
  • 35 kg bodyweight and above: Four tablets as a single initial dose, 4 tablets again after 8 hours and then 4 tablets twice daily (morning and evening) for the following two days (total course of 24 tablets).

Dosage in Patients with Hepatic or Renal Impairment

  • No specific pharmacokinetic studies have been carried out in patients with hepatic or renal impairment. Most patients with acute malaria present with some degree of related hepatic and/or renal impairment. In clinical studies, the adverse event profile did not differ in patients with mild or moderate hepatic impairment compared to patients with normal hepatic function. No specific dose adjustments are needed for patients with mild or moderate hepatic impairment.
  • In clinical studies, the adverse event profile did not differ in patients with mild or moderate renal impairment compared to patients with normal renal function. There were few patients with severe renal impairment in clinical studies. There is no significant renal excretion of lumefantrine, artemether and dihydroartemisinin (DHA) in healthy volunteers and while clinical experience in this population is limited, no dose adjustment is recommended.
  • Caution should be exercised when administering Coartem Tablets in patients with severe hepatic or renal impairment.

Warnings

Prolongation of the QT Interval

Some antimalarials (e.g., halofantrine, quinine, quinidine) including Artemether/Lumefantrine Tablets have been associated with prolongation of the QT interval on the electrocardiogram. Artemether/Lumefantrine Tablets should be avoided in patients:

Use of QT Prolonging Drugs and Other Antimalarials

Drug Interactions with CYP3A4

Drug Interactions with CYP2D6

Recrudescence

  • Food enhances absorption of artemether and lumefantrine following administration of Artemether/Lumefantrine Tablets.
  • Patients who remain averse to food during treatment should be closely monitored as the risk of recrudescence may be greater. In the event of recrudescent P. falciparum infection after treatment with Artemether/Lumefantrin Tablets, patients should be treated with a different antimalarial drug.

Hepatic and Renal Impairment

  • Artemether/Lumefantrine Tablets have not been studied for efficacy and safety in patients with severe hepatic and/or renal impairment.

Adverse Reactions

Clinical Trials Experience

Serious Adverse Reactions

The following serious and otherwise important adverse reactions are discussed in greater detail in other sections of labeling:

Clinical Studies Experience

  • 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 rate observed in practice.
  • The data described below reflect exposure to a 6-dose regimen of Artemether/Lumefantrine Tablets in 1,979 patients including 647 adults (older than 16 years) and 1,332 children (16 years and younger). For the 6-dose regimen, Artemether/Lumefantrin Tablets was studied in active-controlled (366 patients) and non-controlled, open-label trials (1,613 patients). The 6-dose Artemether/Lumefantrin Tablets population was patients with malaria between ages 2 months and 71 years: 67% (1,332) were 16 years and younger and 33% (647) were older than 16 years. Males represented 73% and 53% of the adult and pediatric populations, respectively. The majority of adult patients were enrolled in studies in Thailand, while the majority of pediatric patients were enrolled in Africa.
  • Tables 1 and 2 show the most frequently reported adverse reactions (вЙ•3%) in adults and children respectively who received the 6-dose regimen of Artemether/Lumefantrin Tablets. Adverse reactions collected in clinical trials included signs and symptoms at baseline but only treatment emergent adverse events, defined as events that appeared or worsened after the start of treatment, are presented below. In adults, the most frequently reported adverse reactions were headache, anorexia, dizziness, and asthenia. In children, the adverse reactions were pyrexia, cough, vomiting, anorexia, and headache. Most adverse reactions were mild, did not lead to discontinuation of study medication, and resolved.
  • In limited comparative studies, the adverse reaction profile of Artemether/Lumefantrine Tablets appeared similar to that of another antimalarial regimen.
  • Discontinuation of Artemether/Lumefantrin Tablets due to adverse drug reactions occurred in 1.1% of patients treated with the 6-dose regimen overall: 0.2% (1/647) in adults and 1.6% (21/1,332) in children.

Clinically significant adverse reactions reported in adults and/or children treated with the 6-dose regimen of Artemether/Lumefantrine Tablets which occurred in clinical studies at <3% regardless of causality are listed below:

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Artemether/Lumefantrin Tablets. Because these events 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.

  • Hypersensitivity reactions including urticaria and angioedema. Serious skin reactions (bullous eruption) have been rarely reported.

Drug Interactions

Rifampin

Ketoconazole

Antiretroviral Drugs

Prior Use of Mefloquine

  • Administration of three doses of mefloquine followed 12 hours later by a 6-dose regimen of Artemether/Lumefantrine Tablets in 14 healthy volunteers demonstrated no effect of mefloquine on plasma concentrations of artemether or the artemether/DHA ratio. However, exposure to lumefantrine was reduced, possibly due to lower absorption secondary to a mefloquine-induced decrease in bile production. Patients should be monitored for decreased efficacy and food consumption should be encouraged with administration of Artemether/Lumefantrine Tablets.

Hormonal Contraceptives

CYP2D6 Substrates

Sequential Use of Quinine

  • A single dose of intravenous quinine (10 mg/kg bodyweight) concurrent with the final dose of a 6-dose regimen of Artemether/Lumefantrin Tablets demonstrated no effect of intravenous quinine on the systemic exposure of DHA or lumefantrine. Quinine exposure was also not altered. Exposure to artemether was decreased. This decrease in artemether exposure is not thought to be clinically significant. However, quinine and other drugs that prolong the QT interval should be used cautiously following treatment with Artemether/Lumefantrine Tablets due to the long elimination half-life of lumefantrine and the potential for additive QT effects; ECG monitoring is advised if use of drugs that prolong the QT interval is medically required.

Interaction with Drugs that are Known to Prolong the QT Interval

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): C

  • Safety data from an observational pregnancy study of approximately 500 pregnant women who were exposed to Artemether/Lumefantrine Tablets (including a third of patients who were exposed in the first trimester), and published data of over 1,000 pregnant patients who were exposed to artemisinin derivatives, did not show an increase in adverse pregnancy outcomes or teratogenic effects over background rate.
  • The efficacy of Artemether/Lumefantrine Tablets in the treatment of acute, uncomplicated malaria in pregnant women has not been established.
  • Artemether/Lumefantrine Tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
  • Pregnant rats dosed during the period of organogenesis at or higher than a dose of about half the highest clinical dose of 1120 mg artemether-lumefantrine per day (based on body surface area comparisons), showed increases in fetal loss, early resorptions and post implantation loss. No adverse effects were observed in animals dosed at about one-third the highest clinical dose. Similarly, dosing in pregnant rabbits at about three times the clinical dose (based on body surface area comparisons) resulted in abortions, preimplantation loss, post implantation loss and decreases in the number of live fetuses. No adverse reproductive effects were detected in rabbits at two times the clinical dose. Embryo-fetal loss is a significant reproductive toxicity. Other artemisinins are known to be embryotoxic in animals. However, because metabolic profiles in animals and humans are dissimilar, artemether exposures in animals may not be predictive of human exposures [see Nonclinical Toxicology (13.2)]. These data cannot rule out an increased risk for early pregnancy loss or fetal defects in humans.


Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Artemether and lumefantrin in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Artemether and lumefantrin during labor and delivery.

Nursing Mothers

  • It is not known whether artemether or lumefantrine is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Artemether/Lumefantrine Tablets are administered to a nursing woman. Animal data suggest both artemether and lumefantrine are excreted into breast milk. The benefits of breastfeeding to mother and infant should be weighed against potential risk from infant exposure to artemether and lumefantrine through breast milk.

Pediatric Use

  • The safety and effectiveness of Artemether/Lumefantrine Tablets have been established for the treatment of acute, uncomplicated malaria in studies involving pediatric patients weighing 5 kg or more [see Clinical Studies (14.1)]. The safety and efficacy have not been established in pediatric patients who weigh less than 5 kg. Children from non-endemic countries were not included in clinical trials.

Geriatic Use

  • Clinical studies of Artemether/Lumefantrine Tablets did not include sufficient numbers of subjects aged 65 years and over to determine they respond differently from younger subjects. In general, the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy in elderly patients should be considered when prescribing Artemether/Lumefantrine Tablets.

Gender

There is no FDA guidance on the use of Artemether and lumefantrin with respect to specific gender populations.

Race

There is no FDA guidance on the use of Artemether and lumefantrin with respect to specific racial populations.

Renal Impairment

  • No specific pharmacokinetic studies have been performed in patients with either hepatic or renal impairment. Artemether/Lumefantrine Tablets have not been studied for efficacy and safety in patients with severe hepatic and/or renal impairment. Based on the pharmacokinetic data in 16 healthy subjects showing no or insignificant renal excretion of lumefantrine, artemether and DHA, no dose adjustment for the use of Artemether/Lumefantrine in patients with renal impairment is advised. No dosage adjustment is necessary in patients with mild to moderate hepatic impairment [see Dosage and Administration (2.4) and Warnings and Precautions (5.6)].

Hepatic Impairment

  • No specific pharmacokinetic studies have been performed in patients with either hepatic or renal impairment. Artemether/Lumefantrine Tablets have not been studied for efficacy and safety in patients with severe hepatic and/or renal impairment. Based on the pharmacokinetic data in 16 healthy subjects showing no or insignificant renal excretion of lumefantrine, artemether and DHA, no dose adjustment for the use of Artemether/Lumefantrine in patients with renal impairment is advised. No dosage adjustment is necessary in patients with mild to moderate hepatic impairment [see Dosage and Administration (2.4) and Warnings and Precautions (5.6)].

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Artemether and lumefantrin in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Artemether and lumefantrin in patients who are immunocompromised.

Mechanism of Action

  • Artemether/Lumefantrin Tablets, a fixed dose combination of artemether and lumefantrine in the ratio of 1:6, is an antimalarial agent. Artemether is rapidly metabolized into an active metabolite dihydroartemisinin (DHA). The antimalarial activity of artemether and DHA has been attributed to endoperoxide moiety. The exact mechanism by which lumefantrine, exerts its antimalarial effect is not well defined. Available data suggest lumefantrine inhibits the formation of ќ≤-hematin by forming a complex with hemin. Both artemether and lumefantrine were shown to inhibit nucleic acid and protein synthesis.

Structure

Artemether has the empirical formula C16H26O5 with a molecular weight of 298.4, and the following structural formula:

Lumefantrin has the empirical formula C30H32Cl3NO with a molecular weight of 528.9, and the following structural formula:

Pharmacodynamics

There is limited information regarding Artemether and lumefantrin Pharmacodynamics in the drug label.

Pharmacokinetics

Absorption

  • Following administration of Artemether/Lumefantrine Tablets to healthy volunteers and patients with malaria, artemether is absorbed with peak plasma concentrations reached about 2 hours after dosing. Absorption of lumefantrine, a highly lipophilic compound, starts after a lag-time of up to 2 hours, with peak plasma concentrations about 6 to 8 hours after administration. The single dose (4 tablets) pharmacokinetic parameters for artemether, dihydroartemisinin (DHA), an active antimalarial metabolite of artemether, and lumefantrine in adult Caucasian healthy volunteers are given in Table 3. Multiple dose data after the 6-dose regimen of Artemether/Lumefantrine Tablets in adult malaria patients are given in Table 4.
  • Food enhances the absorption of both artemether and lumefantrine. In healthy volunteers, the relative bioavailability of artemether was increased between two- to three-fold, and that of lumefantrine sixteen-fold when Artemether/Lumefantrine Tablets were taken after a high-fat meal compared under fasted conditions. Patients should be encouraged to take Artemether/Lumefantrine Tablets with a meal as soon as food can be tolerated.

Distribution

  • Artemether and lumefantrine are both highly bound to human serum proteins in vitro (95.4% and 99.7%, respectively). Dihydroartemisinin is also bound to human serum proteins (47% to 76%). Protein binding to human plasma proteins is linear.

Biotransformation

Elimination

  • Artemether and DHA are cleared from plasma with an elimination half-life of about 2 hours. Lumefantrine is eliminated more slowly, with an elimination half-life of 3-6 days in healthy volunteers and in patients with falciparum malaria. Demographic characteristics such as sex and weight appear to have no clinically relevant effects on the pharmacokinetics of artemether and lumefantrine.
  • In 16 healthy volunteers, neither lumefantrine nor artemether was found in the urine after administration of Artemether/Lumefantrin and urinary excretion of DHA amounted to less than 0.01% of the artemether dose.

Pharmacokinetics in Special Population

Hepatic and Renal Impairment

  • No specific pharmacokinetic studies have been performed in patients with either hepatic or renal impairment.
  • There is no significant renal excretion of lumefantrine, artemether and DHA in healthy volunteers and while clinical experience in this population is limited, no dose adjustment in renal impairment is recommended.

Pediatric Patients=

  • The PK of artemether, DHA, and lumefantrine were obtained in two pediatric studies by sparse sampling using a population based approach. PK estimates derived from a composite plasma concentration profile for artemether, DHA, and lumefantrine are provided in Table 4.
  • Systemic exposure to artemether, DHA, and lumefantrine, when dosed on a mg/kg body weight basis in pediatric patients (вЙ•5 to <35 kg body weight), is comparable to that of the recommended dosing regimen in adult patients.

Geriatric Patients

  • No specific pharmacokinetic studies have been performed in patients older than 65 years of age.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

  • Carcinogenicity studies were not conducted.

Mutagenesis

  • No evidence of mutagenicity was detected. The artemether: lumefantrine combination was evaluated using the Salmonella and Escherichia/mammalian-microsome mutagenicity test, the gene mutation test with Chinese hamster cells V79, the cytogenetic test on Chinese hamster cells in vitro, and the rat micronucleus test, in vivo.

Impairment of Fertility

  • Pregnancy rates were reduced by about one half in female rats dosed for 2 to 4 weeks with the artemether-lumefantrine combination at 1000 mg/kg (about 9 times the clinical dose based on body surface area comparisons).
  • Male rats dosed for 70 days showed increases in abnormal sperm (87% abnormal) and increased testes weights at 30 mg/kg doses (about one third the clinical dose). Higher doses (about 9 times the clinical dose) resulted in decreased sperm motility and 100% abnormal sperm cells.

Animal Toxicology and/or Pharmacology

  • Neonatal rats (7-21 days old) were more sensitive to the toxic effects of artemether (a component of Artemether/Lumefantrin than older juvenile rats or adults. Mortality and severe clinical signs were observed in neonatal rats at doses which were well tolerated in pups above 22 days old.

Clinical Studies

Treatment of Acute, Uncomplicated P. falciparum Malaria

  • The efficacy of Artemether/Lumefantrin Tablets was evaluated for the treatment of acute, uncomplicated malaria caused by P. falciparum in HIV negative patients in 8 clinical studies. Uncomplicated malaria was defined as symptomatic P. falciparum malaria without signs and symptoms of severe malaria or evidence of vital organ dysfunction. Baseline parasite density ranged from 500/µL - 200,000/µL (0.01% to 4% parasitemia) in the majority of patients. Studies were conducted in partially immune and non-immune adults and children (вЙ•5kg body weight) with uncomplicated malaria in China, Thailand, sub-Saharan Africa, Europe, and South America. Patients who had clinical features of severe malaria, severe cardiac, renal, or hepatic impairment were excluded.
  • The studies include two 4-dose studies assessing the efficacy of the components of the regimen, a study comparing a 4-dose versus a 6-dose regimen, and 5 additional 6-dose regimen studies.
  • Artemether/Lumefantrin Tablets were administered at 0, 8, 24, and 48 hours in the 4-dose regimen, and at 0, 8, 24, 36, 48, and 60 hours in the 6-dose regimen. Efficacy endpoints consisted of:
    • 28 day cure rate, defined as clearance of asexual parasites (the erythrocytic stage) within 7 days without recrudescence by day 28
    • Parasite clearance time (PCT), defined as time from first dose until first total and continued disappearance of asexual parasite which continues for a further 48 hours
    • Fever clearance time (FCT), defined as time from first dose until the first time body temperature fell below 37.5°C and remained below 37.5°C for at least a further 48 hours (only for patients with temperature >37.5°C at baseline)

The modified intent to treat (mITT) population includes all patients with malaria diagnosis confirmation who received at least one dose of study drug. Evaluable patients generally are all patients who had a day 7 and a day 28 parasitological assessment or experienced treatment failure by day 28.

  • Studies 1 and 2: The two studies which assessed the efficacy of Artemether/Lumefantrine Tablets (4 doses of 4 tablets of 20 mg artemether/120 mg lumefantrine) compared to each component alone were randomized, double-blind, comparative, single center, conducted in China. The efficacy results (Table 5) support that the combination of artemether and lumefantrine in Artemether/Lumefantrin Tablets had a significantly higher 28-day cure rate compared to artemether and had a significantly faster parasite clearance time (PCT) and fever clearance time (FCT) compared to lumefantrine.
  • Results of 4-dose studies conducted in areas with high resistance such as Thailand during 1995-96 showed lower efficacy results than the above studies. Therefore, Study 3 was conducted.

Study 3: Study 3 was a randomized, double-blind, two-center study conducted in Thailand in adults and children (aged вЙ•2 years), which compared the 4-dose regimen (administered over 48 hours) of Artemether/Lumefantrine Tablets to a 6-dose regimen (administered over 60 hours). Twenty-eight day cure rate in mITT subjects was 81% (96/118) for the Artemether/Lumefantrine Tablets 6-dose arm as compared to 71% (85/120) in the 4-dose arm.

Studies 4, 5, 6, 7, and 8: In these studies, Artemether/Lumefantrine Tablets were administered as the 6-dose regimen.

  • In study 4, a total of 150 adults and children aged вЙ•2 years received Artemether/Lumefantrine Tablets. In study 5, a total 164 adults and children вЙ•12 years received Artemether/Lumefantrine Tablets. Both studies were conducted in Thailand.
  • Study 6 was a study of 165 non-immune adults residing in regions non-endemic for malaria (Europe and Colombia) who contracted acute uncomplicated falciparum malaria when traveling in endemic regions.
  • Study 7 was conducted in Africa in 310 infants and children aged 2 months to 9 years, weighing 5 kg to 25 kg, with an axillary temperature вЙ•37.5ºC.
  • Study 8 was conducted in Africa in 452 infants and children, aged 3 months to 12 years, weighing 5 kg to <35 kg, with fever (вЙ•37.5°C axillary or вЙ•38°C rectally) or history of fever in the preceding 24 hours.
  • Results of 28-day cure rate, median parasite clearance time (PCT), and fever clearance time (FCT) for Studies 3 to 8 are reported in Table 6.
  • In all studies, patients’ signs and symptoms of malaria resolved when parasites were cleared.
  • In studies conducted in areas with high transmission rates, such as Africa, reappearance of P. falciparum parasites may be due to recrudescence or a new infection.

The efficacy by body weight category for studies 7 and 8 is summarized in Table 7.
