Used (as the hydrochloride salt) for the treatment of patients with anaplastic lymphoma kinase-positive, metastatic non-small cell lung cancer. It has a role as an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor and an antineoplastic agent. It is an organic heterotetracyclic compound, a member of morpholines, a member of piperidines, a nitrile and an aromatic ketone. It is a conjugate base of an alectinib(1+)."}]
