Indications for BOSULIF:
Treatment of chronic, accelerated, or blast phase Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance or intolerance to prior therapy.
Initially 500mg once daily with food. Continue until disease progression or patient intolerance. Consider dose escalation to 600mg once daily in patients who do not reach complete hematological response (CHR) by Week 8 or a complete cytogenetic response (CCyR) by Week 12, who did not have Grade 3 or higher adverse reactions. Adjust dose for hematologic and non-hematologic toxicity: see full labeling. Hepatic impairment: initially 200mg daily. Renal impairment (CrCl 30–50mL/min): initially 400mg daily; (CrCl <30mL/min): initially 300mg daily.
<18yrs: not established.
Monitor and manage GI toxicity, fluid retention; withhold, reduce dose, or discontinue as necessary. Perform CBC weekly for first month, then monthly; hepatic enzyme tests monthly for first three months (more frequently if transaminase elevations occur); withhold, reduce dose, or discontinue as necessary. Monitor renal function at baseline and during therapy; consider adjusting dose if renal impairment occurs. Pregnancy (Cat.D); avoid. Nursing mothers: not recommended.
Potentiated by concomitant strong or moderate CYP3A and/or P-gp inhibitors (eg, ritonavir, indinavir, nelfinavir, saquinavir, ketoconazole, boceprevir, telaprevir, itraconazole, voriconazole, posaconazole, clarithromycin, telithromycin, nefazodone, conivaptan, fluconazole, darunavir, erythromycin, diltiazem, atazanavir, aprepitant, amprenavir, fosamprenavir, crizotinib, imatinib, verapamil, grapefruit products, ciprofloxacin); avoid. Antagonized by concomitant strong or moderate CYP3A inducers (eg, rifampin, phenytoin, carbamazepine, St. John’s Wort, rifabutin, phenobarbital, bosentan, nafcillin, efavirenz, modafinil, etravirine); avoid. Antagonized by proton pump inhibitors (eg, lansoprazole); consider short-acting antacids or H2 blockers instead; separate dosing by more than 2hrs. May potentiate drugs that are P-gp substrates (eg, digoxin).
Tyrosine kinase inhibitor.
Diarrhea, nausea, thrombocytopenia, vomiting, abdominal pain, rash, anemia, pyrexia, fatigue; fluid retention (monitor), hepatic toxicity.
Hepatic (CYP3A4); 94% protein bound.
Fecal (primary), renal.
Tabs 100mg—120; 500mg—30
