- Registration Number
- NCT04075955

- CR-CSSS Champlain-Charles-Le Moyne
- Brief Summary
Olanzapine is frequently used off-label as an adjunct antiemetic in clinical oncology settings. North American oncology guidelines recommend it as salvage therapy and as add-on to the standard triple regimen; some suggest it may also be effective as an initial triple therapy (olanzapine replacing the NK-1 antagonist) based on phase II and III trials.
This prospective, multi-center, open-label study aims to evaluate the feasibility of a large scale randomised controlled trial to compare the effectiveness and tolerability of 5mg orally once daily olanzapine in triple antiemetic therapy versus the standard treatment of aprepitant + ondansetron + dexamethasone in treatment-naive patients receiving the first cycle of a highly emetogenic chemotherapy. Secondary outcomes include effectiveness, tolerability and quality of life assessments. Effectiveness will be measured with complete response and complete remission rates in each treatment arms. Tolerability and patient quality of life will be evaluated with a standardised side effect form and validated questionnaires; ESAS-R and FLIE.
The role of olanzapine-based triple therapy in prevention of chemotherapy-induced nausea and vomiting remains founded on low-quality evidence. To the investigator's knowledge, this study will be the first large scale direct comparison of 5mg olanzapine versus aprepitant in triple therapy.

- Primary Outcome Measures
Name Time Method Number of patients recruited 5 months At least 60 patients over 5 months meet the eligibility criteria and agree to participate.
Eligible patients' interest to participate 5 months At least 35% of all eligible patients agree to participate
Completion of the diary 5 months At least 75% of recruited patients complete 100% of their patient diary.
Cost 5 months The total cost of the study does not exceed 10,000$
Number of centres 5 months The study can be done at two sites.
- Secondary Outcome Measures
Name Time Method Compare effectiveness of olanzapine 5mg versus standard aprepitant in a triple antiemetic therapy in patients receiving a first cycle of highly emetogenic chemotherapy in regard of proportion of participant with complete response in the overall phase. 0 to 120 hours Overall phase was defined as 0 to 120 hours following initiation of chemotherapy.
Complete response was defined as no nausea, no vomiting and no rescue therapy. Intensity of nausea episodes will be measured with a 0 to 10 visual scale. Intensity of vomiting episodes will be measured with a 0 to 10 visual scale.Compare effectiveness of olanzapine 5mg versus standard aprepitant in a triple antiemetic therapy in patients receiving a first cycle of highly emetogenic chemotherapy in regard of proportion of participant with complete remission in the overall phase. 0 to 120 hours Overall phase was defined as 0 to 120 hours following initiation of chemotherapy.
Complete remission was defined as no vomiting and no rescue therapy. Intensity of vomiting episodes will be measured with a 0 to 10 visual scale.Compare tolerability of olanzapine 5mg versus standard aprepitant in a triple antiemetic therapy in patients receiving a first cycle of highly emetogenic chemotherapy in regard of prevalence of adverse events due to the antiemetic therapy in each arm. During the complete duration of the first cycle of chemotherapy (1 cycle is 14 to 28 days) Proportion of patients who experienced adverse events associated with each of the treatment arms. Adverse events obtained according to the ESAS-R questionnaire and a follow-up interview at the second cycle of chemotherapy.
Definition and gradation of adverse events would be following the Common Terminology Criteria for Adverse Events (CTCAE) 5th edition.Compare patient's assessment of quality of life between those receiving olanzapine 5mg and those receiving standard aprepitant in a triple antiemetic therapy in patients receiving a first cycle of highly emetogenic chemotherapy. 0 to 120 hours Quality of life score obtained according to the FLIE questionnaire
