<h2 id="medical-uses">Medical uses</h2> <p>Crizotinib is <a href="/facts/Indicated/DLdGwxDY">indicated</a> for the treatment of metastatic non-small cell lung cancer (NSCLC) or relapsed or refractory, systemic anaplastic large cell lymphoma (ALCL) that is ALK-positive.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a><a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p><p>It is also indicated for the treatment of unresectable, recurrent, or refractory inflammatory anaplastic lymphoma kinase (ALK)-positive myofibroblastic tumors (IMT).<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a><a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p> <h2 id="mechanism-of-action">Mechanism of action</h2> <p>Crizotinib has an <a href="/facts/Aminopyridine/QVj6lavK">aminopyridine</a> structure, and functions as a <a href="/facts/Protein_kinase/U4DQVhW3">protein kinase</a> inhibitor by competitive binding within the <a href="/facts/Adenosine_triphosphate/nB9bwgcU">ATP</a>-binding pocket of target kinases.
