GI-05: The Impact of Olanzapine Among Patients Receiving Neoadjuvant Chemotherapy for Gastric Cancer
Source: ClinicalTrials.gov · Last updated 21 Aug 2026
Brief summary (registry, in English)
This is a single-center, randomized, open-label clinical trial designed to evaluate the impact of low-dose olanzapine on weight loss, appetite, and nutritional outcomes in patients with gastric cancer receiving neoadjuvant chemotherapy. Eligible patients will be randomized to receive olanzapine 2.5 mg orally once daily (QD) in addition to standard neoadjuvant chemotherapy, beginning prior to initiation of chemotherapy and continuing until surgical resection. Patients will otherwise receive standard-of-care (SOC) oncologic treatment, with no alterations to chemotherapy regimens or surgical management. The study is designed to prospectively assess whether olanzapine improves appetite, mitigates weight loss, and enhances nutritional status and quality of life (QoL) during neoadjuvant therapy. This study will be conducted at the University of Illinois Cancer Center (UICC) as a single-site investigator-initiated trial, with an anticipated accrual of 26 participants over 2 years.
