Indications for SPRYCEL:
Newly diagnosed Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in chronic phase. Chronic, accelerated, or myeloid or lymphoid blast phase Ph+ CML with resistance or intolerance to prior therapy including imatinib. Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) with resistance or intolerance to prior therapy.
Swallow whole. ≥18yrs: Chronic phase CML: 100mg once daily. Doses of up to 140mg once daily have been used. Accelerated phase CML, myeloid or lymphoid blast CML, Ph+ ALL: 140mg once daily. Doses of up to 180mg once daily have been used. Treat until disease progression or unable to tolerate. Concomitant CYP3A4 inhibitors (see Interactions): consider reducing dose. Concomitant CYP3A4 inducers (see Interactions): consider increasing dose. See full labeling for dose adjustments with toxicity.
<18yrs: not established.
Monitor for signs/symptoms of cardiac dysfunction; treat appropriately if occur. Congenital long QT syndrome. Proarrhythmic conditions. Cumulative high-dose anthracycline therapy. Hypokalemia, hypomagnesemia; correct electrolyte imbalances before starting and during therapy. Monitor for pleural effusions. Increased risk of pulmonary arterial hypertension (PAH); evaluate for signs/symptoms of underlying cardiopulmonary disease before and during treatment; permanently discontinue if occurs. Obtain CBCs every 2 weeks for 12 weeks, then every 3 months thereafter (chronic phase CML) or weekly for the first 2 months, then monthly thereafter (advanced phase CML or Ph+ ALL). Permanently discontinue if severe skin reactions (eg, Stevens-Johnson syndrome) occur. Increased risk of tumor lysis syndrome in advanced stage disease and/or high tumor burden. Maintain adequate hydration. Correct uric acid levels before therapy and monitor electrolytes. Hepatic impairment. Elderly. Pregnancy. Use effective contraception during and for 30 days after last dose. Nursing mothers: not recommended.
Avoid potent CYP3A4 inhibitors (eg, ketoconazole, itraconazole, clarithromycin, ritonavir, atazanavir, indinavir, nefazodone, nelfinavir, saquinavir, telithromycin, voriconazole), grapefruit juice. May be antagonized by strong CYP3A4 inducers (eg, dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, phenobarbital), St. John's wort: not recommended. Separate dosing of antacids by at least 2hrs; H2 blockers, proton pump inhibitors: not recommended. May potentiate drugs metabolized by CYP3A4 (eg, cyclosporine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, ergot alkaloids). Caution with concomitant anticoagulants or drugs that inhibit platelet function. Caution with antiarrhythmics or other drugs that may lead to QT prolongation.
Tyrosine kinase inhibitor.
Myelosuppression (eg, severe thrombocytopenia, neutropenia, anemia), fluid retention, diarrhea, headache, dyspnea, musculoskeletal pain, rash, fatigue, nausea, severe hemorrhage (eg, CNS, GI); QT prolongation, cardiac events, PAH, severe skin reactions.
