Safety

CAPRELSA is indicated for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable locally advanced or metastatic disease. Use CAPRELSA in patients with indolent, asymptomatic or slowly progressing disease only after careful consideration of the treatment-related risks of CAPRELSA.¹

Warnings and Precautions¹

Because of the risk of QT prolongation, Torsades de pointes, and sudden death, CAPRELSA is available only through a restricted distribution program called the CAPRELSA REMS program. Only prescribers and pharmacies certified with the program are able to prescribe and dispense CAPRELSA.

Adverse Events¹

Per-Patient Incidence of Selected Adverse Reactions Occurring at a Higher Incidence in CAPRELSA-Treated Patients During Randomized Treatment (Between-Arm Difference of ≥5% [All Grades])

• CTCAE version 3 was used to grade adverse events.
• Includes abdominal pain, abdominal pain upper, lower abdominal pain, and abdominal discomfort.
• Includes rash (erythematous, generalized, macular, maculo-papular, papular, pruritic, and exfoliative), dermatitis, dermatitis bullous, generalized erythema, and eczema.
• Includes nail disorder, nail bed inflammation, nail bed tenderness, paronychia, nail bed infection, and nail infection.
• Included due to the increased incidence of severe fatigue in the CAPRELSA group compared to the placebo group.
• Includes laryngitis, nasopharyngitis, pharyngitis, sinusitis, upper respiratory tract infection, acute sinusitis, rhinitis, and tracheitis.
• 69% had QT prolongation >450 ms and 7% had QT prolongation >500 ms by ECG using Fridericia correction.
• Includes corneal edema, corneal opacity, corneal dystrophy, corneal pigmentation, keratopathy, arcus lipoides, corneal deposits, acquired corneal dystrophy.

Important Safety Information, including Boxed WARNING, for CAPRELSA

• Do not use in patients with congenital long QT syndrome
• CAPRELSA can prolong the QT interval in a concentration-dependent manner. Torsades de pointes, ventricular tachycardia and sudden deaths have occurred in patients treated with CAPRELSA
• Do not start CAPRELSA treatment in patients whose QTcF interval (corrected QT interval, Fridericia) is greater than 450 ms or who have a history of Torsades de pointes, bradyarrhythmias, or uncompensated heart failure. CAPRELSA has not been studied in patients with ventricular arrhythmias or recent myocardial infarction
• Stop CAPRELSA in patients who develop a QTcF greater than 500 ms until QTcF returns to less than 450 ms. Dosing of CAPRELSA can then be resumed at a reduced dose
• Because of the risk of QT prolongation, obtain an ECG and serum potassium, calcium, magnesium, and thyroid-stimulating hormone (TSH) at baseline, 2-4 weeks and 8-12 weeks after starting treatment with CAPRELSA, and every 3 months thereafter. Following any dose reduction or interruptions greater than 2 weeks, conduct QT assessments as described above
• Severe skin reactions (including Stevens-Johnson syndrome and Toxic Epidermal Necrolysis), some leading to death, have occurred in patients treated with CAPRELSA. For severe skin reactions, refer patients for urgent medical advice. Systemic therapies e.g., steroids, may be appropriate in such cases and permanent discontinuation of CAPRELSA is recommended
• Photosensitivity reactions can occur during CAPRELSA treatment and up to 4 months after treatment discontinuation
• Interstitial lung disease (ILD) or pneumonitis, including fatalities, has occurred in patients treated with CAPRELSA. Interrupt CAPRELSA for acute or worsening pulmonary symptoms and discontinue CAPRELSA if ILD is confirmed
• Ischemic cerebrovascular events, including fatalities, occurred in patients treated with CAPRELSA. The safety of resumption of CAPRELSA therapy after resolution of an ischemic cerebrovascular event has not been studied. Discontinue CAPRELSA in patients who experience a severe ischemic cerebrovascular event
• Serious hemorrhagic events, including fatalities, occurred in patients treated with CAPRELSA. Do not administer CAPRELSA to patients with a recent history of hemoptysis of ≥1/2 teaspoon of red blood. Discontinue CAPRELSA in patients with severe hemorrhage
• Heart failure, including fatalities, occurred in patients treated with CAPRELSA. Monitor for signs and symptoms of heart failure. Consider discontinuation of CAPRELSA in patients with heart failure. Heart failure may not be reversible upon stopping CAPRELSA
• Diarrhea of Grade 3 or greater severity occurred in patients receiving CAPRELSA. If diarrhea occurs, carefully monitor serum electrolytes and ECGs to enable early detection of QT prolongation resulting from dehydration. Interrupt CAPRELSA for severe diarrhea and upon improvement resume CAPRELSA at a reduced dose
• Increased dosing of thyroid replacement therapy was required in 49% of CAPRELSA-treated patients. Obtain TSH at baseline, at 2-4 weeks and 8-12 weeks after starting treatment with CAPRELSA, and every 3 months thereafter. If signs or symptoms of hypothyroidism occur, examine thyroid hormone levels and adjust thyroid replacement therapy accordingly
• Hypertension, including hypertensive crisis, has occurred in patients treated with CAPRELSA. Monitor all patients for hypertension. Dose reduction or interruption for hypertension may be necessary. If hypertension cannot be controlled, do not resume CAPRELSA
• Reversible posterior leukoencephalopathy syndrome (RPLS) has occurred in patients treated with CAPRELSA. Consider this syndrome in any patient presenting with seizures, headache, visual disturbances, confusion or altered mental function. In clinical studies, three of four patients who developed RPLS while taking CAPRELSA also had hypertension. Discontinue CAPRELSA treatment in patients with RPLS
• Avoid administration of CAPRELSA with anti-arrhythmic drugs and other drugs that may prolong the QT interval
• Vandetanib exposure is increased in patients with impaired renal function. Reduce the starting dose to 200 mg in patients with moderate to severe renal impairment and monitor the QT interval closely. There is no information available for patients with end-stage renal disease requiring dialysis
• CAPRELSA is not recommended for patients with moderate and severe hepatic impairment, as safety and efficacy have not been established
• CAPRELSA has the potential to adversely affect wound healing. Withhold for at least 1 month prior to elective surgery. Do not administer CAPRELSA for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of treatment with CAPRELSA after resolution of wound healing complications has not been established
• CAPRELSA can cause fetal harm when administered to a pregnant woman. Women of childbearing potential should avoid pregnancy and be advised that they must use effective contraception during CAPRELSA treatment and for at least 4 months following the last dose of CAPRELSA
• The most commonly reported adverse drug reactions (>20%) seen with CAPRELSA and with a between arm difference of ≥5% are diarrhea/colitis (57%), rash (53%), acneiform dermatitis (35%), hypertension (33%), nausea (33%), headache (26%), upper respiratory tract infections (23%), decreased appetite (21%), and abdominal pain (21%)
• CAPRELSA REMS Program: Because of the risks of QT prolongation, Torsades de pointes, and sudden death, CAPRELSA is available only through the CAPRELSA REMS Program. Only prescribers and pharmacies certified with the restricted distribution program are able to prescribe and dispense CAPRELSA.
