Ziftomenib: uses, dosing, side effects & brands

The following clinically significant adverse reactions are described elsewhere in the labeling: Differentiation Syndrome [see Warnings and Precautions ( 5.1 )] QTc Interval Prolongation [see Warnings and Precautions ( 5.2 )] The most common adverse reactions (≥20%) are infection without an identified pathogen, hemorrhage, diarrhea, nausea, fatigue, edema, bacterial infection, musculoskeletal pain, differentiation syndrome, pruritus, febrile neutropenia, and transaminases increased. ( 6.1 ) The most common laboratory abnormalities (≥10%) are aspartate aminotransferase increased, potassium decreased, albumin decreased, alanine aminotransferase increased, sodium decreased, creatinine increased, alkaline phosphatase increased, bilirubin increased, potassium increased.

Relapsed or Refractory AML with an NPM1 Mutation The safety of KOMZIFTI for the treatment of patients with relapsed or refractory AML with an NPM1 mutation was evaluated in KO-MEN-001…

Strong or Moderate CYP3A4 Inhibitors: Monitor more frequently for adverse reactions. ( 7.1 ) Strong or Moderate CYP3A4 Inducers: Avoid concomitant use. ( 7.1 ) Proton Pump Inhibitors: Avoid concomitant use. ( 2.4 , 7.1 ) H2 Receptor Antagonists and Antacids: Avoid concomitant use. If concomitant use cannot be avoided, modify KOMZIFTI administration time. ( 2.4 , 7.1 ) Drugs that Prolong the QTc Interval: Avoid concomitant use. If concomitant use is unavoidable, monitor patients more frequently for QTc interval prolongations. ( 5.2 , 7.1 ) 7.1 Effect of Other Drugs on KOMZIFTI Strong or Moderate CYP3A4 Inhibitors Monitor patients more frequently for KOMZIFTI-associated adverse reactions. Ziftomenib is primarily metabolized by CYP3A. Concomitant use of KOMZIFTI with strong or moderate CYP3A4 inhibitors increases ziftomenib exposure [see Clinical Pharmacology ( 12.3 )], which may increase the risk of adverse reactions such as QT prolongation. Strong or Moderate CYP3A4 Inducers Avoid concomitant use of KOMZIFTI with strong or moderate CYP3A4 inducers. Ziftomenib is primarily metabolized by CYP3A. Concomitant use of KOMZIFTI with strong or moderate CYP3A4 inducers may decrease ziftomenib exposure [see Clinical Pharmacology ( 12.3 )] , which may reduce the efficacy of KOMZIFTI. Gastric Acid Reducing Agents Concomitant administration of ziftomenib with proton pump inhibitors (PPIs) decreases ziftomenib exposure [see Clinical Pharmacology ( 12.3 )] , which may reduce the efficacy of KOMZIFTI. Avoid concomitant use of KOMZIFTI with PPIs. Avoid concomitant use of KOMZIFTI with H2 receptor antagonists (H2RAs) or locally acting antacids. If concomitant use cannot be avoided, modify KOMZIFTI administration time [see Dosage and Administration ( 2.4 )] . Drugs that Prolong the QT Interval Avoid concomitant use of KOMZIFTI with other product(s) with a known potential to prolong the QTc interval. If concomitant use cannot be avoided, obtain ECGs when initiating, during concomitant use, and as clinically indicated [see Warnings and Precautions ( 5.2 )] . Interrupt KOMZIFTI if the QTc interval is > 500 ms or the change from baseline is > 60 ms [see Dosage and Administration ( 2.5 )] . Ziftomenib causes QTc interval prolongation [see Clinical Pharmacology ( 12.2 )] . Concomitant use of KOMZIFTI with other products that prolong the QTc interval may result in a greater increase in the QTc interval and adverse reactions associated with QTc interval prolongation, including Torsades de pointes, other serious arrhythmias, and sudden death [see Warnings and Precautions ( 5.2 )] .
