Indications for ALUNBRIG:
Treatment of patients with anaplastic lymphoma kinase (ALK)-positive, metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib.
Swallow whole. Initially 90mg once daily for first 7 days; if tolerated, increase to 180mg once daily until disease progression or unacceptable toxicity. If dose interrupted for ≥14 days (not due to adverse reactions), resume at 90mg daily for 7 days then re-titrate. Concomitant strong CYP3A inhibitors: avoid; if required, reduce Alunbrig dose by ~50%. Dose modifications or dose reduction levels: see full labeling.
Monitor for new or worsening respiratory symptoms esp. during 1st week of initiation; if occurs, withhold and evaluate for ILD/pneumonitis; resume at same dose for Grade 1 or reduced dose for Grade 2 severity; permanently discontinue for Grade 3/4 or recurrent Grade 1/2 ILD/pneumonitis. Monitor BP after 2 weeks and at least monthly thereafter; withhold for Grade 3 hypertension despite optimal antihypertensive therapy; resume at reduced dose upon improvement to Grade 1 severity; consider permanent discontinuation for Grade 4 or recurrent Grade 3 hypertension. Monitor HR and BP regularly; if symptomatic bradycardia occurs, withhold and evaluate any concomitant drugs that are known to cause bradycardia; resume at same or reduced dose after resolution; discontinue for life-threatening bradycardia if no contributing concomitant medication identified. Withhold and evaluate for new or worsening visual symptoms of Grade ≥2 severity; resume at reduced doses upon recovery to Grade 1 or baseline; permanently discontinue for Grade 4 visual disturbances. Monitor CPK, lipase, and amylase levels during treatment; withhold for Grade 3/4 elevation; resume at same or reduced dose upon recovery to Grade 1 or baseline. Assess fasting serum glucose prior to initiation and periodically thereafter; if not adequately controlled with optimal antihyperglycemics, withhold then consider dose reduction, or permanently discontinue based on severity. Embryo-fetal toxicity. Pregnancy: avoid. Use effective non-hormonal contraception during treatment and for at least 4 months (females) or at least 3 months (males) after final dose. Nursing mothers: not recommended (during and for 1 week after final dose).
Avoid concomitant strong CYP3A inhibitors (eg, boceprevir, cobicistat, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, clarithromycin, itraconazole, ketoconazole, posaconazole, voriconazole, conivaptan); see Adult. Avoid grapefruit or grapefruit juice. Avoid concomitant strong CYP3A inducers (eg, rifampin, carbamazepine, phenytoin, St. John's wort). May reduce efficacy of CYP3A substrates (eg, hormonal contraceptives). Caution with antihypertensives that cause bradycardia.
