Study summary

This randomized phase III trial studies how well netupitant/palonosetron hydrochloride and dexamethasone with prochlorperazine or olanzapine work compared to netupitant/palonosetron hydrochloride and dexamethasone in improving chemotherapy-induced nausea and vomiting in patients with breast cancer. Antiemetic drugs, such as prochlorperazine and olanzapine, may help lessen nausea and vomiting in patients with breast cancer treated with chemotherapy.

Read the detailed description

PRIMARY OBJECTIVES:

I. To determine if control of nausea at cycle 2 in participants who experienced chemotherapy-induced nausea and vomiting (CINV) at cycle 1 is improved by the addition of either prochlorperazine or olanzapine to the control arm of netupitant, palonosetron and dexamethasone.

SECONDARY OBJECTIVES:

I. To determine if olanzapine is more effective than prochlorperazine in controlling nausea at cycle 2 in participants who experienced CINV at cycle 1 when used in combination with netupitant, palonosetron and dexamethasone.

II. To determine if control of vomiting at cycle 2 in patients who experienced CINV at cycle 1 is improved by the addition of either prochlorperazine or olanzapine to the control arm of netupitant, palonosetron and dexamethasone.

III. To determine if olanzapine is more effective than prochlorperazine in controlling vomiting at cycle 2 in participants who experienced CINV at cycle 1 when used in combination with netupitant, palonosetron and dexamethasone.

TERTIARY OBJECTIVES:

I. To create an empirically-based algorithm predicting nausea from breast cancer chemotherapy regimens that takes into account not only state-of-the-art anti-emetic regimens but also participant factors such as age, race, education, ethnicity, quality of life (QOL), alcohol consumption, susceptibility to nausea, expectancy, anxiety, level of nausea on the day prior to treatment, and prior history of nausea.

II. To compare the effects of the interventions on QOL, as assessed by the Functional Assessment of Cancer Therapy- General (FACT-G), by following the same procedures described under the primary aim and the first secondary aim, using change in the FACT-G scores as the response.

III. To provide preliminary data on the frequency and severity of sleep disturbance, fatigue, anxiety, and dizziness, across treatment conditions.

IV. To provide preliminary data on biological factors (e.g. glutathione [GSH] recycling, genetic markers) that may help identify a subgroup of patients at high risk for development of cancer-related or treatment-related side effects, or response to treatment.

OUTLINE:

PART I: Patients receive 1 cycle of standard of care chemotherapy.

PART II: Patients with a nausea score >= 3 at least once on the diary at cycle 1 chemotherapy are randomized into 1 of 3 groups at cycle 2.

GROUP I: Within 1 hour prior to chemotherapy, patients receive netupitant/palonosetron hydrochloride orally (PO) on day 1. Within 30 minutes prior to chemotherapy, patients also receive dexamethasone PO on days 1-4. Patients also receive placebo PO with chemotherapy every 8 hours (Q8H) on days 1-4.

GROUP II: Patients receive netupitant/palonosetron hydrochloride and dexamethasone as in Group I. Patients also receive prochlorperazine PO Q8H and placebo PO with chemotherapy on days 1-4.

GROUP III: Patients receive netupitant/palonosetron hydrochloride and dexamethasone as in Group I. Patients also receive olanzapine PO and placebo PO Q8H with chemotherapy on days 1-4.

After completion of study treatment, patients are followed up for 30 days.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2018 to primary completion in Apr 2024, 71 months.

Results were first posted in Sep 2025, 1 year 5 months after primary completion.

Of 328 non-industry phase 3 interventional studies under Breast Neoplasms, half reached primary completion within 79 months of starting (the median), counting those still running; a quarter within 50 and three quarters within 127. This study's 71 months is below that.

Counting every sponsor, half of 600 studies reached it within 59 months; a quarter within 36 and three quarters within 96.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 25, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
