Description

Rolapitant is a potent, highly selective, long-acting Neurokinin-1 (NK-1) receptor antagonist approved for the prevention of delayed chemotherapy-induced nausea and vomiting (CINV) in adults. Delayed-phase CINV typically occurs >24 hours after chemotherapy treatment and is principally mediated by Neurokinin-1 and its ligand Substance P, which is released in the gut following chemotherapy administration. Neurokinin-1 is also known as Tachykinin Receptor 1 (TACR1), Neurokinin 1 Receptor (NK1R), and Substance P Receptor (SPR). By blocking Substance P from interacting with NK-1 receptors in the gut and the central nervous system, rolapitant prevents late-phase CINV. Unlike other available NK-1 receptor antagonists, rolapitant is not an inhibitor of Cytochrome P450 enzyme CYP3A4 and has a long elimination half-life, allowing a single dose to prevent both acute and late-phase CINV during the first 120 hours post-chemotherapy.

Pharmacology

Indication

This drug is indicated in adults in combination with other antiemetics for the prevention of delayed nausea and vomiting associated with emetogenic chemotherapy.

Associated Conditions
Pharmacodynamics
Not Available
Mechanism of action

Rolapitant is an orally active, highly selective Neurokinin-1 Receptor (NK1R) antagonist. NK1 receptors are located primarily in the gut and central nervous system and are activated by Substance P following chemotherapy administration. By binding to the NK1 receptor, rolapitant prevents binding of its ligand Substance P, which is released in the gut following chemotherapy administration.

Absorption

Following administration of rolapitant, plasma concentrations reached peak levels in about 4 hours.

Volume of distribution

460 L

Protein binding

Rolapitant is 99.8% bound to human plasma protein.

Metabolism

Rolapitant is metabolized primarily by Cytochrome P450 enzyme 3A4 (CYP3A4) to its major active and circulating metabolite M19 (C4-pyrrolidine-hydroxylated rolapitant).

Route of elimination

Rolapitant was found to be 14.2% renally excreted and 73% fecally excreted. Of the fecally excreted compounds

Half life

Mean terminal half life ranged from 169 to 183 hours (~7 days).

Clearance

0.96 L/hour

Toxicity

Most common adverse reactions occurring in >3% of patients receiving moderately emetogenic chemotherapy and combinations of anthracycline and cyclophosphamide included decreased appetite, neutropenia, dizziness, dyspepsia, urinary tract infection, stomatitis, and anemia. Most common adverse reactions occurring in patients receiving cisplatin-based highly emetogenic chemotherapy included neutropenia, hiccups, and abdominal pain.
