Drug interactions

Major drug interactions

Major:

trastuzumab etrasimod

Applies to: trastuzumab and Velsipity (etrasimod)

Using etrasimod together with trastuzumab may increase the risk of serious and potentially life-threatening infections.

Because etrasimod effects can continue for up to 5 weeks after the last dose, interactions with other drugs may occur for some time even after you have stopped taking it.

Talk to your doctor if you have any questions or concerns.

Contact your doctor immediately if you develop signs and symptoms of infection such as fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination during or after treatment with these drugs.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

etrasimod Food/Lifestyle

Applies to: Velsipity (etrasimod)

Grapefruit juice may increase the blood levels of etrasimod.

You should avoid grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with etrasimod unless directed otherwise by your doctor.

Talk to your doctor if you have any questions or concerns.

Contact your doctor if your condition changes or you experience increased side effects, such as fever, high temperature or flu-like symptoms, severe headache, confusion, seizures, dizziness, tiredness, lightheadedness, chest pain, shortness of breath, or irregular or abnormal heartbeat, blurriness or shadows in the center of your vision, and nausea, vomiting, abdominal pain, anorexia, or jaundice and/or dark urine.

Disease interactions

16 potential interactions Applies to: 16 conditions, including High Blood Pressure, Heart Failure, Heart Attack, Peripheral Neuropathy, and Arrhythmia.

Arrhythmia

Moderate:

trastuzumab

Trastuzumab has a moderate potential interaction with Arrhythmia.

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.

Velsipity

The etrasimod in Velsipity has a major potential interaction with Cardiovascular Conditions and Disorders.

Etrasimod is contraindicated in patients who have experienced in the last 6 months myocardial infarction, unstable angina pectoris, stroke, transient ischemic attack, decompensated heart failure requiring hospitalization, and Class III or IV heart failure. It is also contraindicated in patients with history of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial block, unless the patient has a functioning pacemaker. Advice from a cardiologist should be sought if treatment is being considered in patients with significant QT prolongation, arrhythmias requiring treatment with Class Ia or Class II anti-arrhythmic drugs or QT prolonging drugs, unstable ischemic heart disease, Class I or III heart failure, history of cardiac arrest, cerebrovascular disease, uncontrolled hypertension, resting heart rate less than 50 beats per minute, symptomatic bradycardia, recurrent cardiogenic syncope, severe untreated sleep apnea, history of Mobitz type I second degree AV block, unless the patient has a functioning pacemaker.

Pulmonary toxicity includes dyspnea, interstitial pneumonitis, pulmonary infiltrates, pleural effusions, non-cardiogenic pulmonary edema, pulmonary insufficiency and hypoxia, acute respiratory distress syndrome, and pulmonary fibrosis. Patients with symptomatic intrinsic lung disease or with extensive tumor involvement of the lungs, resulting in dyspnea at rest may be at increased risk of pulmonary toxicity and appear to have more severe toxicity. Patients should be monitored for pulmonary symptoms. Permanently discontinue treatment with these agents in patients diagnosed with interstitial lung disease or pneumonitis and institute appropriate care.

Skin Cancer

Moderate:

Velsipity

The etrasimod in Velsipity has a moderate potential interaction with Skin Cancer.

Cases of malignancies, including skin malignancies have been reported in patients treated with some sphingosine -1-receptor (S1P) receptor modulators. Skin examinations are recommended prior and during treatment in all patients, particularly in those with risk factors for skin cancer. Suspicious skin lesions should be promptly evaluated, and patients at increased risk should wear protective clothing and use sunscreen with high protection factor.

Thrombocytopenia

Moderate:

trastuzumab

Trastuzumab has a moderate potential interaction with 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.

Vaccination

Moderate:

Velsipity

The etrasimod in Velsipity has a moderate potential interaction with Vaccination.

Etrasimod increases the risk of infections as it decreases the peripheral lymphocyte counts. Treatment initiation should be delayed in patients with an active infection until the infection is resolved.

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.
