Olanzapine and 5-HT3 With or Without Dexamethasone to Prevent CINV

Plain-language summary
Nausea and vomiting caused by chemotherapy are considered by patients as the main side effects of cancer treatment, which affect the quality of treatment and life.At present, NCCN guidelines have recommended three or four drug regimens for highly emetic chemotherapy (HEC) to prevent vomiting, all containing dexamethasone.However, its side effects such as moderate to severe insomnia, hyperglycemia, dyspepsia, upper abdominal discomfort, irritability, increased appetite, weight gain and acne are gathering increasing concerns.For certain patients, the use of dexamethasone should be avoided.Analysis shows that olanzapine can replace the effect of dexamethasone.Hence, the investigators initiated this prospective, multi-center, phase III study to validate the dexamethasone-free protocol: removing dexamethasone from a three drug regimen containing olanzapine, dexamethasone, and 5-HT3RA.
