Central Nervous System Penetration The central nervous system cns is a common site of progression in ALK -positive, crizotinib-treated nsclc patients.

Patients typically reported visual events in the morning or evening. Complex renal cysts were seen very infrequently in patients treated with crizotinib. Once infectious causes for diarrhea have been excluded, standard nonpharmacologic measures dietary adjustment and hydration and antidiarrheal medications such as loperamide can be used.

Severe acute interstitial lung disease after crizotinib therapy in a patient with EML4-ALK—positive non-small-cell lung cancer. A number of reports describe patients who continued to respond systemically, but who progressed in the cns 17 Importantly, patients with sinus bradycardia were asymptomatic and had no associated electrocardiographic changes such as PR or QT prolongation.

In profilethe most frequently described grades 3 and 4 ae s were elevated alanine aminotransferase 3.

Visual effects in anaplastic lymphoma kinase ALK xe 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.

Over time, the visual effects occurred less frequently.


Peripheral edema occurs in up to one third of patients taking crizotinib, being the main cumulative effect of this agent Table i. Activity and safety of crizotinib in patients with ALK-positive non-small-cell lung cancer: Table IV Incidence of hepatic laboratory abnormalities among patients in profile and profile Food and Drug Administration and Health Canada; however, we also highlight emerging data concerning second-generation Alk inhibitors.

Permanently discontinue in case of further grade 4 recurrence. Anaplastic lymphoma kinase ALK rearrangements have been identified as key oncogenic drivers in a small subset of non-small-cell lung cancers nsclc s.

Crizotinib is a small-molecule receptor tyrosine kinase inhibitor initially designed to target c-Met, but subsequently found to be active against Alk.

Managing treatment–related adverse events associated with Alk inhibitors

Although the possibility of serious ae s from crizotinib is relatively low, proactive monitoring is important to mitigate the risk. Moderate inhibitors of CYP3A4 should be used with caution, and crizotinib toxicity should be monitored.

The main gastrointestinal effects of crizotinib include nausea, diarrhea, vomiting, and constipation. The central nervous system cns is a common site of progression in ALK -positive, crizotinib-treated nsclc patients.

Managing treatment–related adverse events associated with Alk inhibitors

Symptoms of liver dysfunction should prompt assessment for possible drug-induced liver injury. 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.

Over time, the visual and gastrointestinal effects tend to improve. The newer agents are generally more potent than crizotinib and structurally distinct.

Pulmonary toxicity from crizotinib is a rare, but potentially life-threatening, adverse reaction. Withhold until recovery to grade 1 or lower.

Although Alk inhibitors such as crizotinib are well tolerated, there is a potential for adverse events to occur. Because crizotinib is metabolized in the liver, hepatic impairment can lead to higher drug concentrations.

Hepatotoxicity Grade 3 or 4 alt or ast elevation and Grade infice or lower total bilirubin ast and alt Grade 2: Tables ii and iii detail parameters to monitor and dose modifications.


Table ii describes the key toxicities and suggests parameters to monitor. The events were short-lived, typically lasting less than 1 minute. Crizotinib is associated with two main cardiac effects: Given the effectiveness of targeted therapies, patients will often be taking the agents for long periods of time.

In clinical practice, patients on crizotinib do not require baseline or routine ophthalmologic assessments. Grade 3 or 4 alt or ast elevation and Grade 1 or lower total bilirubin. Most patients dee experience liver enzyme elevation do so within the first 2 months of treatment.

Proactive monitoring, treatment, and education concerning those adverse events will help to optimize the therapeutic index of the drugs. Articles from Current Oncology are provided here courtesy of Multimed Inc. In a retrospective analysis of patients from a single institution enrolled in the profile and trials, most patients experienced at least 1 episode of an absolute decrease in heart rate of more than 10 bpm from baseline before treatment. Management of constipation includes dietary modification and standard laxatives.

However, liver enzyme elevation can occur later on as well. Testosterone levels and quality of life in diverse male patients with cancers unrelated to androgens. If further reduction is required, the dose can be modified to mg taken orally once daily.

Visual Effects The most common side kndice of crizotinib is visual disturbance. Nat Rev Clin Oncol. In the profile trial, a heart rate decrease by a mean of Resume at same dose schedule.
