About AKYNZEO® AKYNZEO is the first and only 5-HT3 and NK1 receptor antagonists fixed combination approved for the prevention of chemotherapy-induced acute and delayed nausea and vomiting.

INDICATION AKYNZEO (fosnetupitant/palonosetron) injection 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 highly emetogenic cancer chemotherapy. Limitations of Use AKYNZEO injection has not been studied for the prevention of nausea and vomiting associated with anthracycline plus cyclophosphamide chemotherapy. AKYNZEO is a combination of palonosetron, a serotonin-3 (5-HT3) receptor antagonist, and fosnetupitant, a substance P/neurokinin-1 (NK-1) receptor antagonist: palonosetron prevents nausea and vomiting during the acute phase and fosnetupitant prevents nausea and vomiting during both the acute and delayed phase after cancer chemotherapy. IMPORTANT SAFETY INFORMATION 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-HT3 receptor antagonists.Serotonin syndrome has been reported with 5-HT3 receptor antagonists alone but particularly with concomitant use of serotonergic drugs. Serotonin syndrome can be life threatening. Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms: mental status changes, autonomic instability, neuromuscular symptoms, seizures, and gastrointestinal symptoms. Patients should be monitored for the emergence of serotonin syndrome, and if symptoms occur, discontinue AKYNZEO and initiate supportive treatment. Patients should be informed of the increased risk of serotonin syndrome, especially if AKYNZEO is used concomitantly with other serotonergic drugs. Adverse Reactions Most common adverse reactions (≥3%) for AKYNZEO capsules are headache, asthenia, dyspepsia, fatigue, constipation and erythema. The safety profile of AKYNZEO injection was generally similar to AKYNZEO capsules. Drug Interactions Use with caution in patients receiving concomitant medications primarily metabolized by CYP3A4. The plasma concentrations of CYP3A4 substrates can increase when co-administered with AKYNZEO. The inhibitory effect on CYP3A4 can last for multiple days Dexamethasone doses should be reduced when given with AKYNZEO. A more than two- fold increase in the systemic exposure of dexamethasone was observed 4 days after a single infusion of fosnetupitant.Consider the potential effects of increased plasma concentrations of midazolam or other benzodiazepines metabolized via CYP3A4 (alprazolam, triazolam) when administering with AKYNZEO. When administered with netupitant, the systemic exposure to midazolam was significantly increased. Avoid concomitant use of AKYNZEO in patients on chronic use of a strong CYP3A4 inducer such as rifampin as this may decrease the efficacy of AKYNZEO. Use in Specific Populations Avoid use of AKYNZEO in patients with severe hepatic impairment, severe renal impairment, or end-stage renal disease.Advise women of potential risk to fetus; limited data are available; may cause fetal harm.
