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

China275 participantsStarted 2023-04-15

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
