Brand Names:
Akynzeo
11 DESCRIPTION AKYNZEO (300 mg netupitant/0.5 mg palonosetron) capsules are an oral combination product of netupitant, a substance P/neurokinin 1 (NK-1) receptor antagonist, and palonosetron hydrochloride, a serotonin-3 (5-HT 3 ) receptor antagonist. Both netupitant and palonosetron hydrochloride are anti-nausea and anti-emetic agents.

Uses
1 INDICATIONS AND USAGE AKYNZEO capsules is indicated in combination with dexamethasone in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy. AKYNZEO capsules is a combination of palonosetron and netupitant: palonosetron prevents nausea and vomiting during the acute phase and netupitant prevents nausea and vomiting during both the acute and delayed phase after cancer chemotherapy. AKYNZEO for injection and AKYNZEO injection are indicated in combination with dexamethasone in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy.
Dosage
2 DOSAGE AND ADMINISTRATION Recommended Dosage AKYNZEO capsules: The recommended dosage is one AKYNZEO capsule administered 1 hour prior to the start of chemotherapy, with or without food. ( 2.1 ) Preparation and Administration AKYNZEO injection is supplied either as a Ready-to-Use (with hanger) vial or a To-be-Diluted vial. (2.2) AKYNZEO for injection requires dilution prior to administration. ( 2.3 ) See full prescribing information for information on preparation, administration, and incompatibilities for each product. (2.2, 2.3, 2.4 ) 2.1 Recommended Dosage The recommended dosages of AKYNZEO and dexamethasone in adults for the prevention of nausea and vomiting associated with administration of emetogenic chemotherapy are shown in Table 1.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are found elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Serotonin Syndrome [see Warnings and Precautions ( 5.2 )] Most common adverse reactions (≥3%) for AKYNZEO capsules are headache, asthenia, dyspepsia, fatigue, constipation and erythema ( 6.1 ) The safety profile of AKYNZEO for injection was generally similar to that seen with AKYNZEO capsules. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact HELSINN at 1-844-357-4668 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
Interactions
7 DRUG INTERACTIONS CYP3A4 Substrates: inhibition of CYP3A4 by netupitant can result in increased plasma concentrations of the concomitant drug for 6 days after single dosage administration of AKYNZEO; avoid concomitant CYP3A4 substrates for one week, if feasible. If not avoidable, consider dose reduction of the CYP3A4 substrate ( 7.1 ) CYP3A4 Inducers (e.g., rifampin): decreased plasma concentrations of netupitant; avoid use ( 7.2 ) 7.1 Effects of AKYNZEO on Other Drugs Interaction with CYP3A4 Substrates Netupitant is a moderate inhibitor of CYP3A4. AKYNZEO should be used with caution in patients receiving concomitant medications that are primarily metabolized through CYP3A4. A single oral dose of netupitant 300 mg significantly inhibits CYP3A4 for 6 days.
Warnings
5 WARNINGS AND PRECAUTIONS Hypersensitivity reactions, including anaphylaxis, have been reported in patients receiving palonosetron, one of the components of AKYNZEO, with or without known hypersensitivity to other 5-HT 3 receptor antagonists. ( 5.1 ) Serotonin syndrome has been reported with 5-HT 3 receptor antagonists alone but particularly with concomitant use of serotonergic drugs. If such symptoms occur, discontinue AKYNZEO and initiate supportive treatment. If concomitant use of AKYNZEO with other serotonergic drugs is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome. 4 CONTRAINDICATIONS None. None ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Limited available data with AKYNZEO use in pregnant women are insufficient to inform a drug- associated risk of adverse developmental outcomes. In animal reproduction studies with netupitant, no effects on embryo-fetal development were observed following daily oral administration in pregnant rats during the period of organogenesis at doses up to 3.7 times the human AUC (area under the plasma concentration-time curve) at the recommended single dose to be given with each cycle of chemotherapy.
