Gastrointestinal Effects The main gastrointestinal effects of crizotinib include nausea, diarrhea, vomiting, and constipation.

A number of reports describe patients who continued to respond systemically, but who progressed in the cns 17 Severe acute interstitial lung disease after crizotinib therapy in a patient with EML4-ALK—positive non-small-cell lung cancer.
Crizotinib is associated with two main cardiac effects: The exact mechanism of this difference has not been fully elucidated. The central nervous system cns is a common site of progression in ALK -positive, crizotinib-treated nsclc patients. N Engl J Med. Indlce second-generation Alk inhibitors are currently in phase i and ii testing.
Managing treatment–related adverse events associated with Alk inhibitors
Nonetheless, crizotinib can be taken with or without food. Although Alk inhibitors such as crizotinib are well tolerated, there is a potential for adverse events to occur.
That effect—usually a metallic taste or lack of taste—is common with chemotherapy. Second-Generation Alk Inhibitors Several second-generation Alk inhibitors are currently in phase i iindice ii testing.
Isolated central nervous system progression on crizotinib: In patients treated on profilea visual symptom assessment questionnaire was completed on day 1 of each cycle. Patients taking crizotinib should avoid grapefruit juice, a strong CYP3A4 inhibitor.
Table iii describes management of QT prolongation. The recommended dose of crizotinib is mg taken orally twice daily. Complex renal cysts were seen very infrequently in patients treated with crizotinib. However, in patients with unexplained pulmonary symptoms, crizotinib-induced pneumonitis has to be considered in the differential diagnosis.
Resume at mg twice daily b.

Preclinical studies have highlighted the importance of ALK as an oncogenic driver in nsclc and the associated sensitivity to Alk inhibition 17. Liver Enzyme Abnormalities Abnormalities in liver enzymes are frequently observed with crizotinib, and in some cases, significant elevations can occur.
That study demonstrated significant improvements in response rate and progression-free survival in favour of crizotinib, but no overall survival benefit was observed, presumably because of crossover. Moderate inhibitors of CYP3A4 should be used with caution, and crizotinib toxicity should be monitored.

Routine surveillance of the cns should therefore be considered indiice all crizotinib-treated patients. Most patients reported that the visual effects were not at all or only a little bothersome.
Permanent discontinuation because of a hepatic adverse event occurred in 1. Proactive management of ae indkce helps to optimize the therapeutic index of targeted therapies and enhances quality of life for patients. Table IV Incidence of hepatic laboratory abnormalities among patients in profile and profile No specific data address that question, but the product monograph recommends that caution should be exercised during driving or operating machinery by patients who experience vision disorders.
Although the possibility of serious ae s from crizotinib is relatively low, proactive monitoring is important to mitigate the risk. Withhold until recovery to grade 1 or lower. Toxicity Baseline testing Ongoing monitoring Hepatotoxicity astaltalpbilirubin Every 2 weeks xe the first 2 months, then monthly and as clinically indicated More frequent testing for grade 2, 3, or 4 elevation Hematologic effects Complete blood count and differential Monthly and as clinically indicated More frequently if grade 3 or 4 abnormalities observed, or if fever letagte infection occurs Cardiac QTc prolongation and bradycardia Concomitant medication list, physical exam heart rate and blood pressureelectrocardiogram, electrolytes Concomitant medication list Physical exam heart rate leharte blood pressure Periodic monitoring for patients at risk for abnormalities with electrocardiogram and electrolytes Ophthalmologic None If persistent or severe symptoms, consider ophthalmologic evaluation Pneumonitis None As clinically indicated by symptoms and imaging Hypogonadism In men: QT interval prolongation and bradycardia.
The solubility of crizotinib is pH-dependent: If further reduction is required, the dose can be modified to mg taken orally once daily.
Heart rate decrease during crizotinib treatment and potential correlation to clinical response. For many patients, taking crizotinib with food is a helpful strategy for alleviating the nausea 8.
Table i describes lletarte ae s commonly seen across the indide studies in which the safety profile of crizotinib is quite consistent. Medications such as proton pump inhibitors, histamine H2 blockers, and antacids may therefore have an effect on bioavailability, although the clinical relevance of this interaction is unknown.
