The newer agents are generally more potent than crizotinib and structurally distinct. 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

Typically, this disturbance occurs early median time to onset of less than 2 weeks. Symptomatic reduction in free testosterone levels secondary to crizotinib use in male cancer patients. Cardiac Effects Crizotinib is associated with two main cardiac effects: Treating ALK-positive lung cancer—early successes and future challenges. Although QT prolongation was observed in patients on crizotinib, no associated arrhythmias were observed Nat Rev Clin Oncol.

Grade 2, 3, or 4 alt or ast elevation and concurrent grade 2, 3, or 4 total bilirubin elevation c. Mechanisms of acquired crizotinib resistance in ALK-rearranged lung cancers. Patients who develop cns metastases as an isolated site of progression can often undergo cns radiation and continue crizotinib to control systemic disease Inanaplastic lymphoma kinase ALK gene rearrangements were identified in nsclc 12.


Routine surveillance of the cns should therefore be considered in all crizotinib-treated patients. An exploratory analysis looked at the correlation between heart rate decrease and clinical response, and further study is required. QT interval prolongation and bradycardia. Crizotinib should be used with caution in patients with a predisposition to QT prolongation or in those on concomitant QT-prolonging medications.

Withhold until recovery to grade 1 or lower. A practical question about ability to drive often comes up at crizotinib start. Rare Complications of Crizotinib Complex renal cysts were seen very infrequently in patients treated with crizotinib.

Similarly, they indicated no or minimal impact of visual effects on insice of daily living The field of oncology has entered an era of molecularly targeted therapy.

Symptoms of liver dysfunction should prompt assessment for possible drug-induced liver injury. Although the possibility of serious ae s from crizotinib is relatively low, proactive monitoring is important to mitigate the risk.

Canadian Cancer Statistics In profile andsevere pneumonitis was seen in 1. The recommended dose of crizotinib is mg taken orally twice daily. One approach to overcoming resistance is the development of next-generation Alk inhibitors Although those inhibitors are generally well tolerated, they have a unique side effect profile that differs from that of traditional cytotoxic therapy.

Visual disturbance is a unique side effect associated with changes in ambient lighting—for example, moving from a dark to a light room. 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. The most common side effect of crizotinib is visual disturbance. Gastrointestinal Effects The main gastrointestinal effects of crizotinib include nausea, diarrhea, vomiting, and constipation.


Most patients reported that the visual effects letartte not at all or only a little bothersome. Pulmonary toxicity from crizotinib inddice a rare, but potentially life-threatening, adverse reaction. A phase i trial in advanced ALK -positive nsclc profile demonstrated an impressive One published case of grade 3 esophagitis resolved with crizotinib discontinuation Infice, liver enzyme elevation can occur later on as well. The present review focuses on the management of treatment-related ae s associated with Alk inhibitors.

In Canada, patients are currently screened for ALK by immunohistochemistry, with fluorescence in situ hybridization used for confirmation.

A phase iii study in advanced ALK -positive nsclc progressing on a first-line platinum-based doublet compared crizotinib with standard second-line chemotherapy using pemetrexed or docetaxel profile We typically advise patients to observe how their vision is affected in low light conditions and, if they are significantly affected a xe of patientsto refrain from driving at those times of day until symptoms improve.

Food and Drug Administration and Indce Canada; however, we also highlight emerging data concerning second-generation Alk inhibitors. Successful crizotinib re-treatment has been described with the addition of steroid premedication, but further data are required to evaluate the safety of that maneuver Please review our privacy policy.

That effect—usually a metallic taste or lack of taste—is common with chemotherapy. Cases of fatal crizotinib-induced pneumonitis have occurred Permanently discontinue petarte case of further grade 3 or 4 recurrence.
