†95% confidence interval.


Complete response in the delayed phase was higher with AKYNZEO among patients receiving AC chemotherapy treatment during all cycles (cycles 2–6)1

After completion of cycle 1, patients had the option to participate in a multiple-cycle extension, receiving the same treatment as assigned in cycle 11,3

  • 1438 patients (99%) completed cycle 11
  • 1286 patients (88%) continued treatment in the multiple-cycle extension1

AKYNZEO study design in patients receiving AC chemotherapy treatment1

Phase III, multinational, multicenter, randomized, double-blind, double-dummy, parallel-group study evaluating AKYNZEO capsules (n=724) vs oral palonosetron (n=725) in AC-based chemotherapy, which was considered MEC at the time the study was conducted1,3:

  • 98% of patients were undergoing chemotherapy for breast cancer3
  • Day 1: AKYNZEO capsule + dexamethasone 12 mg vs palonosetron 0.5 mg + dexamethasone 20 mg1
  • Days 2-3: No antiemetic treatment1

*AKYNZEO injection has not been studied for the prevention of nausea and vomiting associated with AC chemotherapy.

  • AC=anthracycline plus cyclophosphamide; CINV=chemotherapy-induced nausea and vomiting; MEC=moderately emetogenic chemotherapy.
