Generic Name and Formulations:
Sunitinib (as malate) 12.5mg, 25mg, 37.5mg, 50mg; gelatin caps.

Company:
Pfizer Inc.
Indications for SUTENT:
Advanced renal cell carcinoma (RCC).

Adult:
50mg once daily for 4 weeks, then 2 weeks off (see full labeling). May adjust dose in increments or decrements of 12.5mg. Concomitant strong CYP3A4 inhibitors (see Interactions): may reduce dose to 37.5mg daily. Concomitant strong CYP3A4 inducers (see Interactions): may increase to max 87.5mg daily.

Children:
Not established.

Warnings/Precautions:
Hepatotoxicity; may be severe or fatal. Monitor liver function tests before starting, during each cycle of treatment and as clinically needed; interrupt if Grade 3 or 4 hepatic adverse events occur and discontinue if no resolution; if severe liver function changes or signs/symptoms of failure, do not restart. Cardiovascular events: monitor for CHF during therapy, and LVEF at baseline and periodically; interrupt or reduce dose if LVEF <50% and >20% below baseline; discontinue if CHF occurs. History of QT prolongation or proarrythmic conditions (eg, bradycardia, electrolyte disturbances); perform periodic ECG, monitor electrolytes. Monitor BP. Suspend therapy if severe hypertension, seizures, or pancreatitis develops. Obtain CBCs, platelets, serum chemistries at start of each cycle. Concomitant exposure to risk factors (eg, IV bisphosphonates therapy or dental disease) may increase the risk of osteonecrosis of the jaw; avoid or consider preventive dentistry prior to treatment. Risk of tumor lysis syndrome: monitor closely in RCC and GIST patients with high tumor burden. Monitor for thyroid dysfunction; obtain baseline levels prior to treatment. Monitor blood glucose levels during and after treatment discontinuation. Monitor for proteinuria; perform baseline and periodic urinalyses; interrupt and reduce dose if 24-hr urine protein ≥3g; discontinue if nephrotic syndrome or repeat urine protein ≥3g persists. Undergoing major surgery. Stress (monitor for adrenal insufficiency). Discontinue if severe cutaneous reactions (eg, erythema multiforme, SJS, TEN) develop; do not restart if diagnosis suspected. ESRD on dialysis. Severe hepatic impairment. Pregnancy (Cat.D; avoid). Nursing mothers: not recommended.

Interactions:
May be potentiated by strong CYP3A4 inhibitors (eg, ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole), grapefruit; consider reducing dose or use alternate drug. May be antagonized by CYP3A4 inducers (eg, dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital); consider increasing dose or use alternate drug. Concomitant St. John's wort: not recommended. Caution with concomitant antiarrhythmics.

Pharmacological Class:
Multikinase inhibitor.

Adverse Reactions:
Fatigue, asthenia, fever, diarrhea, nausea, vomiting, mucositis/stomatitis, dyspepsia, abdominal pain, constipation, hypertension, peripheral edema, rash, hand-foot syndrome, skin discoloration, dry skin, hair color changes, altered taste, headache, back pain, arthralgia, extremity pain, cough, dyspnea, anorexia, bleeding; hepatotoxicity, left ventricular dysfunction, QT prolongation, osteonecrosis of the jaw, tumor lysis syndrome, thyroid dysfunction, impaired wound healing, hypoglycemia, thrombotic microangiopathy (discontinue if develops), proteinuria, necrotizing fasciitis (discontinue if occurs), others (see full labeling).
