Interactions
7 DRUG INTERACTIONS Acid-Reducing Agents: Avoid coadministration. If coadministration cannot be avoided, take RETEVMO with food (with PPI) or modify its administration time (with H2 receptor antagonist or locally-acting antacid). ( 2.4 , 7.1 ) Strong and Moderate CYP3A Inhibitors: Avoid coadministration. If coadministration cannot be avoided, reduce the RETEVMO dose. ( 2.6 , 7.1 ) Strong and Moderate CYP3A Inducers: Avoid coadministration. ( 7.1 ) CYP2C8 and CYP3A Substrates: Avoid coadministration. If coadministration cannot be avoided, modify the substrate dosage as recommended in its product labeling. ( 7.2 ) Certain P-gp and BCRP Substrates: Avoid coadministration. If coadministration cannot be avoided, modify the substrate dosage as recommended in its product labeling.
Warnings
5 WARNINGS AND PRECAUTIONS Hepatotoxicity : Monitor ALT and AST prior to initiating RETEVMO, every 2 weeks during the first 3 months, then monthly thereafter and as clinically indicated. Withhold, reduce the dose, or permanently discontinue RETEVMO based on severity. ( 2.5 , 5.1 ) Interstitial Lung Disease (ILD)/Pneumonitis : Monitor for new or worsening pulmonary symptoms. Withhold, reduce the dose or permanently discontinue RETEVMO based on severity. ( 2.5 , 5.2 ) Hypertension: Do not initiate RETEVMO in patients with uncontrolled hypertension. Optimize blood pressure (BP) prior to initiating RETEVMO. Monitor BP after 1 week, at least monthly thereafter and as clinically indicated. Withhold, reduce the dose, or permanently discontinue RETEVMO based on severity. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on findings from animal studies, and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , RETEVMO can cause fetal harm when administered to a pregnant woman. There are no available data on RETEVMO use in pregnant women to inform drug-associated risk. Administration of selpercatinib to pregnant rats during the period of organogenesis resulted in embryolethality and malformations at maternal exposures that were approximately equal to the human exposure at the clinical dose of 160 mg twice daily. Advise pregnant women of the potential risk to a fetus.
Storage
Storage and Handling Store at 20°C to 25°C (68°F to 77°F); excursions between 15°C and 30°C (59°F to 86°F) are permitted [see USP Controlled Room Temperature].
