Given that a large number of patients treated with crizotinib are young adults who will be on therapy for relatively long periods of time, such symptoms can be even more distressing. Peripheral edema occurs in up to one third of patients taking crizotinib, being the main cumulative effect of this agent Table i. Small-molecule Alk kinase inhibitors such as crizotinib have transformed the natural history of nsclc for this subgroup of patients. Management of constipation includes dietary modification and standard laxatives.

Dose modifications for crizotinib related adverse events Data on the efficacy of second-generation Alk inhibitors is limited mainly to phase i and ii studies.

Similarly, the focus of the discussion is crizotinib, because that agent is currently the only Alk inhibitor approved by the U. Every 2 weeks during the first 2 months, then monthly and as clinically indicated More frequent testing for grade 2, 3, or 4 elevation.

Managing treatment–related adverse events associated with Alk inhibitors

Over time, the visual effects occurred less frequently. Patients receiving crizotinib also experienced dysgeusia Table i. The visual effects are predominantly grade 1, and in the profile and trials, no patients required dose interruptions or reductions because of them 8 If dose reduction is necessary, mg taken orally twice daily can be used. Copyright Multimed Inc.


Heart rate decrease is a leetarte effect of crizotinib, averaging 2. In patients with significant hepatic dysfunction, crizotinib should be used with caution. 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.

Proactive monitoring, treatment, and education concerning those adverse events will help to optimize the therapeutic index of the drugs. As clinically indicated by symptoms and imaging. Patients who develop cns metastases as an isolated site of progression can often undergo cns radiation and continue crizotinib to control systemic disease Because of the high incidence of baseline pulmonary disease, radiation-related changes, infectious complications, and presence of progressive malignancy, a diagnosis of drug-induced pneumonitis can be difficult to make in lung cancer patients.

In studies, patients were excluded if their serum aspartate aminotransferase ast or alanine aminotransferase ast was more than 2.

Find articles by N. A practical question about ability to drive often comes up at crizotinib start. Changes appeared to be both rapid and reversible on commencement and cessation of dosing.

Anaplastic lymphoma kinase infice, ALKcrizotinib, adverse indcie, lung cancer. The use of targeted therapies for subsets of molecularly-defined cancers has been a paradigm shift in cancer treatment. Prochlorperazine and 5-HT 3 receptor antagonists such as ondansetron should be avoided or used with caution because of the risk of QT prolongation. Once infectious causes for diarrhea have been excluded, standard nonpharmacologic measures dietary adjustment and hydration and antidiarrheal medications such as loperamide can be used.

Aprepitant has not been studied with crizotinib, and as a CYP3A4 substrate and inhibitor, it might lead to increased crizotinib toxicity. Recommended monitoring for patients on crizotinib Visual effects in anaplastic lymphoma kinase ALK -positive advanced non-small cell lung cancer nsclc patients treated with crizotinib [abstract ] J Clin Oncol.


Clinical impact of continued crizotinib administration after isolated central nervous system progression in patients with lung cancer positive for ALK rearrangement. A phase i trial in advanced ALK -positive nsclc profile demonstrated an impressive Canadian Cancer Society; One published case of grade 3 esophagitis resolved with crizotinib discontinuation As such, they may be associated with different ae profiles.

Male hypogonadism associated with advanced cancer: Cardiac Effects Crizotinib is associated with two main cardiac effects: Temporary discontinuation or dose reduction because of a hepatic adverse event occurred in 5.

Global survey of phosphotyrosine signaling identifies oncogenic kinases in lung cancer. Symptoms of liver dysfunction should prompt assessment for possible drug-induced liver injury.

Crizotinib is metabolized predominantly by CYP3A, and so co-administration with strong inhibitors of CYP3A4 such as ketoconazole increases the area under the curve of crizotinib and should be avoided. Patients with ALK rearrangements tend to be younger at diagnosis median age: Given the effectiveness of targeted therapies, patients will often be taking the agents for long periods of time.

There was no associated renal impairment, and the significance of these occurrences is unknown The most xe side effect of crizotinib is visual disturbance.

Permanent discontinuation because of a hepatic adverse event occurred in 1.
