    Purpose This review summarizes the recommendations for the prophylaxis of acute and delayed nausea and vomiting induced by multiple-day chemotherapy, high-dose chemotherapy, and breakthrough nausea and vomiting as agreed at the MASCC/ESMO Antiemetic Guidelines update meeting in Copenhagen in June 2015. Methods A systematic literature search using PubMed from January 01, 2009 through January 06, 2015 with a restriction to papers in English was conducted. Results There were three phase III randomized trials in patients undergoing high-dose chemotherapy and stem cell transplant and eight single arm non-randomized clinical studies (single in patients undergoing transplantation and one in patients receiving multiple-day chemotherapy treatment). We used a total of two randomized clinical trials in this guideline update. For patients receiving treatment for breakthrough chemotherapy-induced nausea and vomiting, a phase III randomized trial investigating the use of olanzapine versus metoclopramide in patients receiving highly emetogenic chemotherapy and a second single arm study looking at the effectiveness of olanzapine were identified. Conclusions It was concluded that for patients receiving high-dose chemotherapy with stem cell transplant, a combination of a 5-HT3 receptor antagonist with dexamethasone and aprepitant (125 mg orally on day 1 and 80 mg orally on days 2 to 4) is recommended before chemotherapy. For patients undergoing multiple-day chemotherapy-induced nausea and vomiting, a 5-HT3 receptor antagonist, dexamethasone, and aprepitant, are recommended before chemotherapy for the prophylaxis of acute emesis and delayed emesis. For patients experiencing breakthrough nausea and vomiting, the available evidence suggests the use of 10 mg oral olanzapine, daily for 3 days. Mild to moderate sedation in this patient population (especially elderly patients) is a potential problem with this agent.

    Olanzapine for the Prevention of Chemotherapy-Induced Nausea and Vomiting
    (Massachusetts Medical Society, 2016-07-14) Navari, Rudolph M.; Qin, Rui; Ruddy, Kathryn J.; Liu, Heshan; Powell, Steven F.; Bajaj, Madhuri; Dietrich, Leah; Biggs, David; Lafky, Jacqueline M.; Loprinzi, Charles L.; Department of Medicine, IU School of Medicine
    BACKGROUND We examined the efficacy of olanzapine for the prevention of nausea and vomiting in patients receiving highly emetogenic chemotherapy. METHODS In a randomized, double-blind, phase 3 trial, we compared olanzapine with placebo, in combination with dexamethasone, aprepitant or fosaprepitant, and a 5-hydroxytryptamine type 3–receptor antagonist, in patients with no previous chemotherapy who were receiving cisplatin (≥70 mg per square meter of body-surface area) or cyclophosphamide–doxorubicin. The doses of the three concomitant drugs administered before and after chemotherapy were similar in the two groups. The two groups received either 10 mg of olanzapine orally or matching placebo daily on days 1 through 4. Nausea prevention was the primary end point; a complete response (no emesis and no use of rescue medication) was a secondary end point. RESULTS In the analysis, we included 380 patients who could be evaluated (192 assigned to olanzapine, and 188 to placebo). The proportion of patients with no chemotherapy-induced nausea was significantly greater with olanzapine than with placebo in the first 24 hours after chemotherapy (74% vs. 45%, P = 0.002), the period from 25 to 120 hours after chemotherapy (42% vs. 25%, P = 0.002), and the overall 120-hour period (37% vs. 22%, P = 0.002). The complete-response rate was also significantly increased with olanzapine during the three periods: 86% versus 65% (P<0.001), 67% versus 52% (P = 0.007), and 64% versus 41% (P<0.001), respectively. Although there were no grade 5 toxic effects, some patients receiving olanzapine had increased sedation (severe in 5%) on day 2. CONCLUSIONS Olanzapine, as compared with placebo, significantly improved nausea prevention, as well as the complete-response rate, among previously untreated patients who were receiving highly emetogenic chemotherapy.

    Olanzapine for the Treatment of Advanced Cancer–Related Chronic Nausea and/or Vomiting
    (American Medical Association, 2020-06) Navari, Rudolph M.; Pywell, Cameron M.; Le-Rademacher, Jennifer G.; White, Patrick; Dodge, Andrew B.; Albany, Costantine; Loprinzi, Charles L.; Medicine, School of Medicine
    Importance: Nausea and vomiting, unrelated to chemotherapy, can be substantial symptoms in patients with advanced cancer. Objective: To evaluate the utility of olanzapine for treating chronic nausea/vomiting, unrelated to chemotherapy, in patients with advanced cancer. Design, setting, and participants: This study is a double-line, placebo-controlled, randomized clinical trial conducted from July 2017 through April 2019, with analysis conducted in 2019. Eligible participants were outpatients with advanced cancer who had persistent nausea/vomiting without having had chemotherapy or radiotherapy in the prior 14 days. Chronic nausea was present for at least 1 week (worst daily nausea numeric rating scores needed to be greater than 3 on a 0-10 scale). Interventions: Patients received olanzapine (5 mg) or a placebo, orally, daily for 7 days. Main outcomes and measures: Patient-reported outcomes were used for study end points. Data were collected at baseline and daily for 7 more days. The primary study end point (the change in nausea numeric rating scores from baseline to the last treatment day) and the study hypothesis were both identified prior to data collection. Results: A total of 30 patients (15 per arm) were enrolled; these included 16 women and 14 men who had a mean (range) age of 63 (39-79) years. Baseline median nausea scores, in all patients, were 9 out of 10 (range, 8-10). After 1 day and 1 week, the median nausea scores in the placebo arm were 9 out of 10 (range, 8-10) on both days, compared with the olanzapine arm scores of 2 out of 10 (range, 2-3) after day 1 and 1 out of 10 (range, 0-3) after 1 week. After 1 week of treatment, the reduction in nausea scores in the olanzapine arm was 8 points (95% CI, 7-8) higher than that of the placebo arm. The primary 2-sided end point P value was <.001. Correspondingly, patients in the olanzapine arm reported less emesis, less use of other antiemetic drugs, better appetite, less sedation, less fatigue, and better well-being. One patient, on the placebo, stopped treatment early owing to lack of perceived benefit. No patients receiving olanzapine reported excess sedation or any other adverse event. Conclusions and relevance: Olanzapine, at 5 mg/d, appeared to be effective in controlling nausea and emesis and in improving other symptoms and quality-of-life parameters in the study population.
