Major

artemether ceritinib

Applies to: Coartem (artemether / lumefantrine) and ceritinib

GENERALLY AVOID: Artemether-lumefantrine may cause prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In clinical trials, asymptomatic prolongation of the Fridericia-corrected QT interval (QTcF) by more than 30 msec from baseline was reported in approximately one-third of patients treated with artemether-lumefantrine, and prolongation by more than 60 msec was reported in more than 5% of patients. A few patients (0.4%) in the adult/adolescent population and no patient in the infant/children population experienced a QTcF greater than 500 msec. However, the possibility that these increases were disease-related cannot be ruled out. In a study of healthy adult volunteers, administration of the six-dose regimen of artemether-lumefantrine was associated with mean changes in QTcF from baseline of 7.45, 7.29, 6.12 and 6.84 msec at 68, 72, 96, and 108 hours after the first dose, respectively. There was a concentration-dependent increase in QTcF for lumefantrine. No subject had a greater than 30 msec increase from baseline nor an absolute increase to more than 500 msec. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

MANAGEMENT: Coadministration of artemether-lumefantrine with other drugs that can prolong the QT interval should generally be avoided. Caution is recommended when these drugs are used following treatment with artemether-lumefantrine due to the long elimination half-life of lumefantrine (3 to 6 days). Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions

Major

ceritinib food

Applies to: ceritinib

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ceritinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because ceritinib is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death. Other, more common side effects such as diarrhea, nausea, vomiting, abdominal pain, hyperglycemia, and bradycardia may also increase.

ADJUST DOSING INTERVAL: Food increases the oral bioavailability of ceritinib. The mechanism of interaction is unknown. Compared to the fast state, administration of a single 500 mg dose of ceritinib with a high-fat meal (approximately 1000 calories; 58 grams of fat) increased ceritinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 41% and 73%, respectively, and administration with a low-fat meal (approximately 330 calories; 9 grams of fat) increased ceritinib Cmax and AUC by 43% and 58%, respectively. A dose of 600 mg or higher taken with a meal is expected to produce systemic exposure exceeding that from a 750 mg dose taken in the fasted state, which may lead to increased adverse effects.

MANAGEMENT: Patients treated with ceritinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Ceritinib should be administered on an empty stomach (i.e., avoid administration within 2 hours of a meal).

lumefantrine food

Applies to: Coartem (artemether / lumefantrine)

GENERALLY AVOID: Coadministration with grapefruit juice may increase the plasma concentrations of artemether and lumefantrine. The mechanism is decreased clearance due to inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. High plasma levels of artemether and lumefantrine may increase the risk of QT interval prolongation and ventricular arrhythmias including torsade de pointes. In clinical trials, asymptomatic prolongation of the Fridericia-corrected QT interval (QTcF) by more than 30 msec from baseline was reported in approximately one-third of patients treated with artemether-lumefantrine, and prolongation by more than 60 msec was reported in more than 5% of patients. A few patients (0.4%) in the adult/adolescent population and no patient in the infant/children population experienced a QTcF greater than 500 msec. However, the possibility that these increases were disease-related cannot be ruled out. In a study of healthy adult volunteers, administration of the six-dose regimen of artemether-lumefantrine was associated with mean changes in QTcF from baseline of 7.45, 7.29, 6.12 and 6.84 msec at 68, 72, 96, and 108 hours after the first dose, respectively. There was a concentration-dependent increase in QTcF for lumefantrine. No subject had a greater than 30 msec increase from baseline nor an absolute increase to more than 500 msec.

ADJUST DOSING INTERVAL: Food enhances the oral absorption of artemether and lumefantrine. In healthy volunteers, the relative bioavailability of artemether increased by two- to threefold and that of lumefantrine by sixteenfold when administered after a high-fat meal as opposed to under fasted conditions.

MANAGEMENT: Patients receiving artemether-lumefantrine therapy should avoid the consumption of grapefruits and grapefruit juice. To ensure maximal oral absorption, artemether-lumefantrine should be taken with food. Inadequate food intake can increase the risk for recrudescence of malaria. Patients who are averse to food during treatment should be closely monitored and encouraged to resume normal eating as soon as food can be tolerated.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
