Margenza (margetuximab) Disease Interactions

There are 2 disease interactions with Margenza (margetuximab):

Moderate

HER2 inhibitors (Includes Margenza) CHF

Moderate Potential Hazard, Moderate plausibility. Applies to: Congestive Heart Failure, Hypertension, Myocardial Infarction, Arrhythmias, History - Myocardial Infarction, Post MI Syndrome

Decreases in left ventricular ejection fraction (LVEF) have been reported with agents that block HER2 activity. Patients who have received prior anthracyclines, those who received anthracycline after stopping therapy with agents that block HER2 activity, or patients who received prior radiotherapy to the chest area may be at higher risk of decreased LVEF. Therapy with these agents should be administered cautiously in patients with a previous history of heart conditions. Evaluate cardiac function before, during, and upon completion of treatment. Withhold or discontinue therapy with agents that block HER2 activity as appropriate, and for a confirmed clinically significant decrease in left ventricular function, or if the LVEF has not improved or has declined further. It is recommended to monitor overall cardiac function and LVEF by echocardiogram or MUGA scan as appropriate.

Moderate

HER2 inhibitors (Includes Margenza) thrombocytopenia

Moderate Potential Hazard, Moderate plausibility. Applies to: Thrombocytopenia

Thrombocytopenia has been reported with the use of agents that block HER2 activity. Monitor platelet counts prior to initiation of therapy and prior to each dose. If appropriate modify the dose according to clinical guidelines. Patients with decreased platelet count and patients on anti-coagulant treatment should be closely monitored during treatment with these agents.

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.
