Netupitant is a selective neurokinin 1 (NK1) receptor antagonist with potential antiemetic activity. Netupitant competitively binds to and blocks the activity of the human substance P/NK1 receptors in the central nervous system (CNS), thereby inhibiting NK1-receptor binding of the endogenous tachykinin neuropeptide substance P (SP), which may result in the prevention of chemotherapy-induced nausea and vomiting (CINV). SP is found in neurons of vagal afferent fibers innervating the brain-stem nucleus tractus solitarii and the area postrema, which contains the chemoreceptor trigger zone (CTZ), and may be elevated in response to chemotherapy. The NK-receptor is a G-protein receptor coupled to the inositol phosphate signal-transduction pathway and is found in both the nucleus tractus solitarii and the area postrema.
Netupitant is a Substance P/Neurokinin-1 Receptor Antagonist. The mechanism of action of netupitant is as a Neurokinin 1 Antagonist, and Cytochrome P450 3A4 Inhibitor, and P-Glycoprotein Inhibitor, and Breast Cancer Resistance Protein Inhibitor.

5.2 Absorption, Distribution and Excretion

Absorption

Upon oral administration of a single dose of netupitant, netupitant started to be measurable in plasma between 15 minutes and 3 hours after dosing. Plasma concentrations reached Cmax in approximately 5 hours. There was a greater than dose-proportional increase in the systemic exposure with the dose increase from 10 mg to 300 mg and a dose-proportional increase in systemic exposure with a dose increase from 300 mg to 450 mg.


Route of Elimination

Primarily fecal.


Volume of Distribution

In cancer patients, Vz/F: 1982 906 L (mean SD).


Clearance

Estimated systemic clearance of 20.3 9.2 L/h (mean SD).


5.3 Metabolism/Metabolites

Once absorbed, netupitant is extensively metabolized to form three major metabolites: desmethyl derivative, M1; N-oxide derivative, M2; and OH-methyl derivative, M3. Metabolism is mediated primarily by CYP3A4 and to a lesser extent by CYP2C9 and CYP2D6. Metabolites M1, M2 and M3 were shown to bind to the substance P/neurokinin 1 (NK1) receptor.


5.4 Biological Half-Life

96 hours with CV% of 61.


5.5 Mechanism of Action

Delayed emesis (vomiting) has been largely associated with the activation of tachykinin family neurokinin 1 (NK1) receptors (broadly distributed in the central and peripheral nervous systems) by substance P. As shown in in vitro and in vivo studies, netupitant inhibits substance P mediated responses.
