Selpercatinib Disease Interactions

There are 7 disease interactions with selpercatinib.

Moderate

Selpercatinib (applies to selpercatinib) bleeding

Moderate Potential Hazard, Moderate plausibility.

Serious including fatal hemorrhagic events can occur with the use of selpercatinib. Care should be exercised when using this agent in patients with bleeding disorders. It is recommended to permanently discontinue treatment in patients with severe or life-threatening hemorrhage.

Moderate

Selpercatinib (applies to selpercatinib) hypertension

Moderate Potential Hazard, Moderate plausibility.

Selpercatinib may cause hypertension and therapy should not be initiated in patients with uncontrolled hypertension. Care should be exercised when using this agent in hypertensive patients. Optimize blood pressure before starting treatment. It is recommended to monitor blood pressure after 1 week, and regularly as clinically indicated. Initiate or adjust anti-hypertensive therapy as appropriate. Withhold, reduce dose, or permanently discontinue treatment based on the severity.

Moderate

Selpercatinib (applies to selpercatinib) ILD/pneumonitis

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Interstitial Pneumonitis

Selpercatinib may cause severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis. Monitor for new or worsening pulmonary symptoms. Withhold therapy and promptly investigate acute or worsening respiratory symptoms suggestive of ILD/pneumonitis (e.g., dyspnea, cough, and fever).

Moderate

Selpercatinib (applies to selpercatinib) liver dysfunction

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

Selpercatinib is metabolized predominantly by CYP450 3A4. The dose of selpercatinib should be reduced in patients with severe hepatic impairment. No dosage modification is recommended for patients with mild or moderate hepatic impairment. Serious hepatic adverse reactions have been reported in patients treated with selpercatinib. Monitor ALT and AST before starting therapy with selpercatinib, every two weeks during the first three months, then monthly thereafter and as clinically indicated. It is recommended to withhold, reduce dose or permanently discontinue treatment based on the severity of selpercatinib-related adverse reactions in patients with hepatic impairment.

Moderate

Selpercatinib (applies to selpercatinib) tumor lysis syndrome

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Renal Dysfunction

Tumor lysis syndrome has been reported with use of selpercatinib in patients with medullary thyroid carcinoma. Patients with rapidly growing tumors, a high tumor burden, renal dysfunction, or dehydration who take selpercatinib may be at increased risk. Closely monitor at-risk patients and consider appropriate prophylaxis, including hydration.

Moderate

Selpercatinib – arrhythmias

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Hypokalemia, Magnesium Imbalance, Hypocalcemia, Electrolyte Abnormalities, Thyroid Disease, Long QT Syndrome, Cardiovascular Disease, Congestive Heart Failure, History - Myocardial Infarction

Selpercatinib can cause concentration-dependent QT interval prolongation. Monitor patients who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, and severe or uncontrolled heart failure. This drug has not been studied in patients with clinically significant active cardiovascular disease or recent myocardial infarction. Assess QT interval, electrolytes, and TSH at baseline and periodically during treatment, adjusting frequency based upon risk factors, including diarrhea or drug interactions. Correct hypokalemia, hypomagnesemia, and hypocalcemia prior to initiating therapy.

Moderate

Selpercatinib – renal dysfunction

Moderate Potential Hazard, Moderate plausibility.

A recommended dose of selpercatinib has not been established for patients with end-stage renal disease. No dosage modification is recommended for patients with mild to severe renal impairment. The use of selpercatinib may increase serum creatinine. It is recommended to consider alternative markers of renal function if persistent elevations in serum creatinine are observed.

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.
