What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Complete Response in the Overall Time Period (0 - 120 Hours Post-chemotherapy)

    Complete response (CR) is defined as no episodes of vomiting and no use of rescue antiemetic medications. Patient reported diaries will be used to measure this outcome.

    Measured: 120 hours post initiating chemotherapy during cycle 1

Secondary outcomes (7)
  1. Rate of Complete Response in the Acute Time Period (0 - 24 Hours Post-chemotherapy)

    Complete response (CR) is defined as no episodes of vomiting and no use of rescue antiemetic medications. Patient reported diaries will be used to measure this outcome.

    Measured: 24 hours post initiating chemotherapy during cycle 1

  2. Rate of Complete Response in the Delayed Time Period (24 - 120 Hours Post-chemotherapy)

    Complete response (CR) is defined as no episodes of vomiting and no use of rescue antiemetic medications. Patient reported diaries will be used to measure this outcome.

    Measured: 24-120 hours post initiating chemotherapy during cycle 1

  3. Rate of no Nausea in the Acute Time Period (0 - 24 Hours Post-chemotherapy)

    Patients will record daily levels of nausea after chemotherapy using a Likert scale ranging from 0-10 (0 indicating no nausea; 10 indicating maximum level of nausea).

    Measured: 24 hours post initiating chemotherapy during cycle 1

  4. Rate of no Nausea in the Delayed Time Period (24 - 120 Hours Post-chemotherapy)

    Patients will record daily levels of nausea using a Likert scale ranging from 0-10 (0 indicating no nausea; 10 indicating maximum level of nausea).

    Measured: 120 hours post initiating chemotherapy during cycle 1

  5. Rate of no Nausea in the Overall Time Period (0 - 120 Hours Post-chemotherapy)

    Patients will record daily levels of nausea using a Likert scale ranging from 0-10 (0 indicating no nausea; 10 indicating maximum level of nausea).

    Measured: 120 hours post initiating chemotherapy during cycle 1

  6. Mean Somnolence Score

    Patients will record daily levels of undesired sedation using a Likert scale ranging from 0 to 10 (0 indicating no undesired sedation; 10 indicating maximum level of undesired sedation).

    Measured: assessed daily, and reported at day 6 post final study treatment

  7. Mean Increased-appetite Score

    Patients will record daily levels of undesired increase in appetite using a Likert scale ranging from 0 to 10 (0 indicating no undesired increase in appetite; 10 indicating maximum level of undesired increase in appetite).

    Measured: assessed daily, and reported at day 6 post final study treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ondansetron, Dexamethasone and Neurokinin-1 Receptor Antagonist (NK1-RA) in people with Gynecologic Cancer, run by University of Michigan Rogel Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 18 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jun 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of Complete Response in the Overall Time Period (0 - 120 Hours Post-chemotherapy) (time frame: 120 hours post initiating chemotherapy during cycle 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2025.
