Nausea and vomiting: what the trials found

Clinical evidence supports the use of several pharmacological agents for managing nausea and vomiting. Olanzapine was evaluated in a Phase 3 trial where median nausea scores were reported as low (0 to 1) across study arms, with mean toxicity scores related to the drug remaining low (0.4 to 2.3) 1.

APF530 demonstrated significant efficacy in managing chemotherapy-induced symptoms; patients showed high rates of Complete Response (CR) during both acute (0-24 hours) and delayed-onset (24-120 hours) phases, as well as overall complete control throughout the first course of chemotherapy 2.

Aprepitant was utilized in multiple studies. In one trial, 54 participants achieved no emesis and required no rescue therapy within 5 days of receiving FOLFOX or FOLFIRI 5. Another study evaluating aprepitant for acute vomiting showed a controlled response in 20 participants with only 2 cases of high-grade toxicity (Grade 3, 4, or 5) 7.

Dexamethasone was evaluated as a treatment; however, statistical analysis did not show a significant difference in the percentage of complete responders across different observation windows (p=0.2344 to p=0.3694) 3.

Recent results — preliminary, needs further review

  • Prochlorperazine was investigated in a Phase 2 trial, but results are not yet corroborated 4.
  • Palonosetron hydrochloride was evaluated regarding emetic episodes and rescue medication requirements, though findings are currently unconfirmed 6.

For the clinician treating this condition

  • Olanzapine is associated with low median nausea scores and low reported toxicity levels in clinical settings 1.
  • APF530 shows high rates of complete response and control for both acute and delayed-onset chemotherapy-induced symptoms 2.
  • Aprepitant can effectively limit emesis and the need for rescue therapy in patients receiving FOLFOX or FOLFIRI regimens [5, 7].
