Applies to: tolterodine and revumenib
Generally avoid

Revumenib causes dose-related prolongation of the QT interval. Coadministration with other agents that can prolong the QT interval may result in additive effects and an increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In clinical trials, QT interval prolongation was reported as an adverse reaction in 29% of patients treated with revumenib at the recommended dosage for relapsed or refractory acute leukemia with a KMT2A translocation. Additionally, Grade 3 QT interval prolongation occurred in 12% of those patients and a greater than 60 msec increase in Fridericia-corrected QT interval (QTcF) from baseline was reported in 18% of patients. 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, hypocalcemia). Moreover, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

Management

It is recommended to avoid revumenib in combination with other drugs that can prolong the QT interval. If concomitant use cannot be avoided, obtain electrocardiograms (ECGs) when initiating, during concomitant use, and as clinically indicated. Serum electrolytes, including potassium, magnesium, and calcium, should be monitored before starting revumenib therapy and monthly during treatment. Revumenib should not be started if baseline QTc is greater than 450 msec. Likewise, treatment should be interrupted and adjusted in accordance with the product labeling in patients who develop QTc prolongation greater than 480 msec. 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. Permanently discontinue revumenib in patients who develop QTc interval prolongation with life-threatening arrhythmia.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

revumenib Food/Lifestyle

Applies to: revumenib
Adjust dosing interval

In pharmacokinetic studies, revumenib was administered while fasting or with a low fat meal. Revumenib has not been studied with meals of higher fat content and the impact on its pharmacokinetic parameters is unknown.

Monitor

Grapefruit, grapefruit juice, grapefruit hybrids, pomelos, star-fruit, and Seville oranges may increase the plasma concentrations of revumenib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The extent and clinical significance are unknown. In pharmacokinetic studies in patients with relapsed or refractory acute leukemia, revumenib area under the concentration-time curve (AUC) and peak plasma concentration (Cmax) increased 2-fold following concomitant use with the potent CYP450 3A4 inhibitors posaconazole, itraconazole, and voriconazole, and 2.5-fold following concomitant use with the potent CYP450 3A4 inhibitor cobicistat. However, clinically significant differences in revumenib pharmacokinetics were not observed when used concomitantly with the moderate CYP450 3A4 inhibitors fluconazole and isavuconazole. In general the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Moreover, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability. Increased exposure to revumenib may increase the risk of QT interval prolongation, which has been associated with ventricular arrhythmias including torsade de pointes and sudden death.

Management

Due to the potential impact of high fat content meals on revumenib absorption and exposure, it is recommended that revumenib be administered while fasting or with a low fat meal (approximately 400-500 calories, with 25% of calories from fat). In addition, if grapefruit, grapefruit juice, grapefruit hybrids, pomelos, star-fruit, or Seville oranges are consumed during treatment with revumenib, assess patient tolerability and monitor for serious adverse effects (e.g., QT prolongation and torsade de pointes arrhythmia, differentiation syndrome, neutropenia, thrombocytopenia).
