Clinical data demonstrate the efficacy of AKYNZEO® in preventing CINV for 5 days

90% of AKYNZEO patients receiving cisplatin had no vomiting and no rescue antiemetic medication use over 5 days1

Complete response rate with a single dose of AKYNZEO Capsules + dexamethasone (primary endpoint) in patients treated with cisplatin1,2
(Primary endpoint)
AKYNZEO complete response data for CINV in overall phase

Study design: Phase II, multicenter, randomized, parallel, double-blind, controlled trial in chemotherapy-naïve patients (N=694) who received CINV prophylaxis with either a single dose of AKYNZEO Capsules + oral dexamethasone 12 mg on Day 1 followed by 8 mg oral dexamethasone once daily on Days 2-4 (n=135) vs a 0.5 mg oral dose of palonosetron + oral dexamethasone 20 mg on Day 1 followed by oral dexamethasone 8 mg twice daily on Days 2-4 (n=136). All patients received cisplatin (median cisplatin dose was 75 mg/m2 for each group) alone or with other chemotherapy agents. The AKYNZEO patients primarily had a diagnosis of lung/respiratory cancer (25.9%), head and neck cancer (24.4%), or ovarian cancer (17.8%). The primary endpoint was complete response in the overall phase (0-120 hours).1,2


AKYNZEO Capsules demonstrated superior efficacy to palonosetron1,2

AKYNZEO for Injection (IV) has established efficacy based on bioequivalence of fosnetupitant to netupitant, and a noninferiority study with palonosetron1,3

≥90% complete response with AKYNZEO in the acute and delayed phase of CINV1

Complete response rate with AKYNZEO Capsules in acute and delayed phase of CINV1
(Secondary endpoint)
AKYNZEO complete response in acute and delayed CINV

FDA-approved AKYNZEO demonstrated significant improvement for secondary endpoints in acute (Day 1) and delayed (Days 2-5) phases of CINV vs palonosetron, including no emesis, no significant nausea, and complete protection (P≤.05)1,2


  • AC=anthracycline-cyclophosphamide; CINV=chemotherapy-induced nausea and vomiting; HEC=highly emetogenic chemotherapy; VAS=visual analog scale.
  • *AKYNZEO for Injection has not been studied for the prevention of nausea and vomiting associated with anthracycline plus cyclophosphamide chemotherapy.
  • Protocol-defined secondary endpoints included rates of no emesis, no significant nausea (VAS <25 mm), and complete protection (complete response + no significant nausea) during acute, delayed, and overall phases.1,2
