---|---|---|
Advanced Malignant Solid Neoplasm Hematopoietic and Lymphoid Cell Neoplasm | Drug: Olanzapine Drug: Placebo Administration Other: Questionnaire Administration | Phase 3 |
PRIMARY OBJECTIVE:
I. To conduct a confirmatory phase III double-blind randomized clinical trial to evaluate the ability of olanzapine to decrease nausea in patients with advanced-cancer associated nausea/vomiting.
SECONDARY OBJECTIVES:
I. To evaluate toxicity associated with olanzapine in patients with advanced-cancer associated nausea/vomiting.
II. To evaluate the effect of olanzapine on appetite, vomiting, sedation, sleep, the use of other antiemetic agents, fatigue, and well-being.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive olanzapine orally (PO) every night on days 1-28.
ARM II: Patients receive placebo PO every night on days 1-2 and olanzapine PO every night on days 3-28.

- Change in nausea score [ Time Frame: Baseline to 24 hours of treatment ]Evaluated using Visual Analogue Scale. Nausea scores at baseline and after the first two days and the change scores, for the first 2 days, will be summarized using mean (standard deviation) and median (range). The change scores from baseline to the end of the first 2 days will be compared between arms using a two-sample t-test or a Wilcoxon rank sum test as appropriate. The difference in nausea change scores from baseline to 2 days post treatment initiation between the two arms will be estimated along with a 95% confidence interval.
- Daily nausea and vomiting scores [ Time Frame: Up to 28 days ]Chronic nausea this is present for at least 1 week (worst daily nausea numeric rating scores needed to be greater than 3 on a 0-10 scale).
- Daily episodes of vomiting/retching (number and time) [ Time Frame: Up to 28 days ]Chronic nausea that is present for at least 1 week (worst daily nausea numeric rating scores needed to be greater than 3 on a 0-10 scale).
- Utilization of rescue therapy [ Time Frame: Up to 28 days ]Baseline evaluation that includes assessment of symptom intensity for appetite, nausea, fatigue, sedation, and pain, all measured and recorded on a numeric rating score. (0 indicated the worst possible; 10, best possible).
- Incidence of adverse events with olanzapine [ Time Frame: Up to 28 days ]Measured by patient reported outcome questionnaires and Common Terminology Criteria for Adverse Events version 5.0.

Exclusion Criteria:
-
Any of the following because this study involves: an agent that has known genotoxic, mutagenic and teratogenic effects:
- Pregnant persons
- Nursing persons
- Received chemotherapy or radiation within the prior 14 days (advanced cancer patients receiving hormonal therapy or targeted therapy that does not come with a recommendation for prophylactic anti-emetic therapy are eligible)
- Receiving treatment with another antipsychotic agent such as risperidone, quetiapine, clozapine, phenothiazine or butyrophenone for =< 30 days prior to registration or planned during protocol therapy (patients may have received prochloperazine and other phenothiazines as prior anti-emetic therapy)
- Those with concurrent use of ethyol; severe cognitive compromise; concurrent use of amifostine; concurrent use of quinolone antibiotic therapy; known hypersensitivity to olanzapine; or have planned chemotherapy or radiation during the 7 days following study initiation
-
Uncontrolled intercurrent illness including, but not limited to:
- Ongoing or active infection (including human immunodeficiency virus [HIV])
- Cardiac disease which, in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient
- Psychiatric illness/social situations that would limit compliance with study requirements
- Inability to swallow oral formulations of the agent(s)
- Tube feeding or nasogastric tube
