Trial Outcomes & Findings for Olanzapine for the Treatment of Chronic Nausea and/or Vomiting in Advanced Cancer Patients (NCT NCT03137121)

NCT ID: NCT03137121

Last Updated: 2021-08-17

Results Overview

Daily nausea scores (the primary objective) on day 1 to 7 of treatment for each patient from the Olanzapine and Placebo group will be measured using the Visual Analogue Scale rankings from 0-10 where 0 is no nausea and 10 is the maximum nausea experienced by a patient. A Visual Analogue Scale is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that can't be directly measured. Patients will be asked to record the average nausea score for each day in a diary and a study nurse will call the patient at the same time each day to remind the patient to record the nausea score and to inquire about any toxicities. The difference in the nausea scores for the patients in each group (Olanzapine and Placebo) will be compared.

PRIMARY outcome

Timeframe: Nausea score from the Visual Analogue Scale will be recorded each day daily for 7 days. An average value calculated will be reported for the 7 day period.

Population: One patient withdrew on their own from the Placebo Group

Daily nausea scores (the primary objective) on day 1 to 7 of treatment for each patient from the Olanzapine and Placebo group will be measured using the Visual Analogue Scale rankings from 0-10 where 0 is no nausea and 10 is the maximum nausea experienced by a patient. A Visual Analogue Scale is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that can't be directly measured. Patients will be asked to record the average nausea score for each day in a diary and a study nurse will call the patient at the same time each day to remind the patient to record the nausea score and to inquire about any toxicities. The difference in the nausea scores for the patients in each group (Olanzapine and Placebo) will be compared.

SECONDARY outcome

Timeframe: Number of emetic episodes for each patient on each day of the seven day treatment.

Population: One patient withdrew from the Placebo Group.

The number of emetic episodes (a secondary outcome) by each patient in each group, Olanzapine \& Placebo, on each day of treatment will be recorded by each patient on each day of treatment in a diary. A study nurse will contact each patient at the same time of each day of the study to ask the patient to record the number of emetic episodes and report any toxicities.The number of emetic episodes for the patients in each Group for each day of the treatment will be compared.

SECONDARY outcome

Timeframe: Daily assessment for 7 days for each patient in Olanzapine & Placebo Groups.

Population: One patient withdrew from Placebo Group.

Adverse events will be measured by patient-reported outcomes questionnaires and the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A study nurse will contact each patient each day of the seven days of treatment to inquire about any toxicities, specifically sedation and appetite. Sedation and appetite will be reported by the patient in each Group on a Visual Analogue Scale of 0 to 10 with 0 being no sedation or no appetite to 10 indicating maximum sedation or maximum appetite.
