Zykadia is a prescription medicine that is used to treat lung cancer.

Description

Ceritinib is a kinase inhibitor for oral administration. The molecular formula for ceritinib is C28H36N5O3ClS. The molecular weight is 558.14 g/mol. Ceritinib is described chemically as 5-Chloro-N4-[2-[(1-methylethyl)sulfonyl]phenyl]-N2-[5-methyl-2-(1-methylethoxy)-4-(4-piperidinyl)phenyl]-2,4-pyrimidinediamine.

The chemical structure of ceritinib is shown below:

Ceritinib is a white to almost white or light yellow powder.

ZYKADIA is supplied as printed hard-gelatin capsules containing 150 mg of ceritinib and the following inactive ingredients: colloidal silicon dioxide, hard gelatin capsule shells, low substituted hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose, and sodium starch glycolate. The capsule shell is composed of FD&C Blue # 2, gelatin, and titanium dioxide.

ZYKADIA is supplied as film-coated tablets containing 150 mg of ceritinib and the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, low-substituted hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose and povidone. The tablet coating contains FD&C Blue # 2 aluminum lake, hypromellose, polyethylene glycol 4000, talc, and titanium dioxide.

 Mechanism of Action

Ceritinib is a kinase inhibitor. Targets of ceritinib inhibition identified in either biochemical or cellular assays at clinically relevant concentrations include ALK, insulin-like growth factor 1 receptor (IGF-1R), insulin receptor (InsR), and ROS1. Among these, ceritinib is most active against ALK. Ceritinib inhibited autophosphorylation of ALK, ALK-mediated phosphorylation of the downstream signaling protein STAT3, and proliferation of ALK-dependent cancer cells in in vitro and in vivo assays.

Ceritinib inhibited the in vitro proliferation of cell lines expressing EML4-ALK and NPM-ALK fusion proteins and demonstrated dose-dependent inhibition of EML4-ALK-positive NSCLC xenograft growth in mice and rats. Ceritinib exhibited dose-dependent anti-tumor activity in mice bearing EML4-ALK-positive NSCLC xenografts with demonstrated resistance to crizotinib, at concentrations within a clinically relevant range.
