About this trial
This phase II trial tests how well olanzapine works in managing cancer cachexia in patients experiencing esophagogastric, hepatopancreaticobiliary, colorectal, or lung cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic) -associated appetite loss while receiving non-curative cancer therapy. Loss of appetite ("anorexia") in the setting of cancer is a key feature of "cachexia," a syndrome associated with loss of weight and muscle as well as weakness and fatigue. Olanzapine is a drug that targets key neurotransmitters (a type of molecule in the central nervous system that transmits messages to the rest of the body) that may stimulate appetite, restore caloric intake, minimize weight loss, and improve quality of life (QOL).

Willingness to provide written informed consent
Individuals >= 18 years of age
Histologically confirmed advanced local or metastatic esophogastric, hepatopancreaticobiliary, colorectal, or lung cancer diagnosis within 12 weeks of screening
≥ 5% weight loss over the past 6 months
Disqualifiers
Plan for, or history of (within 30 days of enrollment), the use of an antipsychotic drug, including, but not limited to, risperidone, quetiapine, clozapine, phenothiazine, or butyrophenone. This limitation does not include prochlorperazine and other phenothiazines as antiemetic therapy. The use of antipsychotics concurrent with protocol therapy will not be allowed
megestrol acetate
cannabinoids (including, but not limited to dronabinol, medical cannabis, over the counter [OTC] cannabinoid products), and/or
Corticosteroids (defined as ≥ 5mg of prednisone [or equivalent per day]), except for standard-of-care chemotherapy-induced nausea and vomiting prophylaxis

Trial outcomes
Primary outcomes
Proportion of patients exhibiting weight gain greater 5%
\>5% weight gain comparing olanzapine 2.5mg (Arm I) vs. placebo (Arm III)
Secondary outcomes
Change in Weight
\>5% weight gain comparing olanzapine 2.5 mg (Arm I) vs. olanzapine 5mg (Arm II) \>5% weight gain comparing olanzapine 5 mg (Arm II) vs. placebo (Arm III)
Anorexia
Patient reported anorexia comparing olanzapine 2.5 mg (Arm 1) vs. olanzapine 5 mg (Arm 2) vs. placebo (Arm 3) Anorexia will be measured using the Functional Assessment of Anorexia-Cachexia Therapy (FAACT), a 12-item subscale of patients' perceptions of appetite (maximum score of 48, higher scores indicate less anorexia). A FAACT score ≤ 37 indicates anorexia.
Appetite
Change in appetite will be measured using the Visual Analog Scale for appetite (VAS), a 10-point scale with a higher score indicating a better appetite. A ≥3-point improvement in appetite at the end of the 12-week placebo-controlled Part A as compared to baseline in each arm will be considered an improvement in appetite.
Nutrition
Nutritional Status will be measured using the Patient- Generated Subjective Assessment Short Form (PG-SGA-SF); scored on a scale of 0-36 with a higher score indicating worse malnutrition.
