Abstract
INTRODUCTION The aim of this study is to rigorously review the efficacy and safety of olanzapine in chemotherapy-induced nausea and vomiting (CINV) settings including (1) at 5- and 10-mg doses, and (2) the setting of highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). METHODS Embase, Pubmed, and Cochrane Library were searched from the establishment of the database through April 18, 2021. The primary efficacy endpoints were the rate of complete response (CR; no emesis and no rescue), in the acute (0-24 h post-chemotherapy), delayed (24-120 h post-chemotherapy), and overall (0-120 h post-chemotherapy) phases. The secondary efficacy endpoints were the rates of complete control (CC, no nausea, and no emesis), for each phase. Safety endpoints were the rate of somnolence, as assessed by Common Terminology Criteria for Adverse Events (CTCAE) criteria. The Mantel-Haenszel, random, or fixed-effect analysis model was used to compute risk ratios and accompanying 95% confidence intervals for each endpoint. For endpoints that statistically favored one arm, absolute risk differences were computed to assess whether there is a 10% or greater difference, used as the threshold for clinical significance by MASCC/ESMO. RESULT Nine studies reported the use of 10 mg olanzapine to prevent CINV; three studies reported the use of 5 mg olanzapine to prevent CINV. When olanzapine was administered at 10 mg for HEC patients, the six endpoints were statistically and clinically better than the control group. For MEC patients, four out of six endpoints were better than the control group. When olanzapine is administered at 5 mg for MEC patients, four endpoints have statistical and clinical advantages. The sedative effects of 10 and 5 mg olanzapine were statistically more significant than those of the control group. The sedative effect of the 10-mg olanzapine group was more significant than that of the 5-mg olanzapine group, both statistically and clinically. CONCLUSION 5 mg olanzapine may be as effective as 10 mg olanzapine for patients with HEC and MEC, and its sedative effect is lower than 10 mg olanzapine. Fewer studies on 5 mg olanzapine have led to uncertain data. In the future, more randomized controlled trials of 5 mg olanzapine are needed to study the balance between the effectiveness and safety of olanzapine.

Abstract
BACKGROUND Olanzapine as an antiemetic represents a new use of an antipsychotic drug. People with cancer may experience nausea and vomiting whilst receiving chemotherapy or radiotherapy, or whilst in the palliative phase of illness. OBJECTIVES To assess the efficacy and safety of olanzapine when used as an antiemetic in the prevention and treatment of nausea and vomiting related to cancer in adults. SEARCH METHODS We searched CENTRAL, MEDLINE and Embase for published data on 20th September 2017, as well as ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform for unpublished trials. We checked reference lists, and contacted experts in the field and study authors. SELECTION CRITERIA We included randomised controlled trials (RCTs) of olanzapine versus any comparator with or without adjunct therapies for the prevention or treatment, or both, of nausea or vomiting in people with cancer aged 18 years or older, in any setting, of any duration, with at least 10 participants per treatment arm. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. We used GRADE to assess quality of evidence for each main outcome. We extracted data for absence of nausea or vomiting and frequency of serious adverse events as primary outcomes. We extracted data for patient perception of treatment, other adverse events, somnolence and fatigue, attrition, nausea or vomiting severity, breakthrough nausea and vomiting, rescue antiemetic use, and nausea and vomiting as secondary outcomes at specified time points. MAIN RESULTS We included 14 RCTs (1917 participants) from high-, middle- and low-income countries, representing over 24 different cancers. Thirteen studies were in chemotherapy-induced nausea and vomiting. Oral olanzapine was administered during highly emetogenic (HEC) or moderately emetogenic (MEC) chemotherapy (12 studies); chemoradiotherapy (one study); or palliation (one study). Eight studies await classification and 13 are ongoing.The main comparison was olanzapine versus placebo/no treatment. Other comparisons were olanzapine versus NK1 antagonist, prokinetic, 5-HT3 antagonist or dexamethasone.We assessed all but one study as having one or more domains that were at high risk of bias. Eight RCTs with fewer than 50 participants per treatment arm, and 10 RCTs with issues related to blinding, were at high risk of bias. We downgraded GRADE assessments due to imprecision, inconsistency and study limitations.Olanzapine versus placebo/no treatmentPrimary outcomesOlanzapine probably doubles the likelihood of no nausea or vomiting during chemotherapy from 25% to 50% (risk ratio (RR) 1.98, 95% confidence interval (CI) 1.59 to 2.47; 561 participants; 3 studies; solid tumours; HEC or MEC therapy; moderate-quality evidence) when added to standard therapy. Number needed to treat for additional beneficial outcome (NNTB) was 5 (95% CI 3.3 - 6.6).It is uncertain if olanzapine increases the risk of serious adverse events (absolute risk difference 0.7% more, 95% CI 0.2 to 5.2) (RR 2.46, 95% CI 0.48 to 12.55; 7 studies, 889 participants, low-quality evidence).Secondary outcomesFour studies reported patient perception of treatment. One study (48 participants) reported no difference in patient preference. Four reported quality of life but data were insufficient for meta-analysis.Olanzapine may increase other adverse events (RR 1.71, 95% CI 0.99 to 2.96; 332 participants; 4 studies; low-quality evidence) and probably increases somnolence and fatigue compared to no treatment or placebo (RR 2.33, 95% CI 1.30 to 4.18; anticipated absolute risk 8.2% more, 95% CI 1.9 to 18.8; 464 participants; 5 studies; moderate-quality evidence). Olanzapine probably does not affect all-cause attrition (RR 0.99, 95% CI 0.57 to 1.73; 943 participants; 8 studies; I² = 0%). We are uncertain if olanzapine increases attrition due to adverse events (RR 3.00, 95% CI 0.13 to 70.16; 422 participants; 6 studies). No participants withdrew due to lack of efficacy.We are uncertain if olanzapine reduces breakthrough nausea and vomiting (RR 0.38, 95% CI 0.10 to 1.47; 501 participants; 2 studies; I² = 54%) compared to placebo or no treatment. No studies reported 50% reduction in severity of nausea or vomiting, use of rescue antiemetics, or attrition.We are uncertain of olanzapine's efficacy in reducing acute nausea or vomiting. Olanzapine probably reduces delayed nausea (RR 1.71, 95% CI 1.40 to 2.09; 585 participants; 3 studies) and vomiting (RR 1.28, 95% CI 1.14 to 1.42; 702 participants; 5 studies).Subgroup analysis: 5 mg versus 10 mgPlanned subgroup analyses found that it is unclear if 5 mg is as effective an antiemetic as 10 mg. There is insufficient evidence to exclude the possibility that 5 mg may confer a lower risk of somnolence and fatigue than 10 mg.Other comparisonsOne study (20 participants) compared olanzapine versus NK1 antagonists. We observed no difference in any reported outcomes.One study (112 participants) compared olanzapine versus a prokinetic (metoclopramide), reporting that olanzapine may increase freedom from overall nausea (RR 2.95, 95% CI 1.73 to 5.02) and overall vomiting (RR 3.03, 95% CI 1.78 to 5.14).One study (62 participants) examined olanzapine versus 5-HT3 antagonists, reporting olanzapine may increase the likelihood of 50% or greater reduction in nausea or vomiting at 48 hours (RR 1.82, 95% CI 1.11 to 2.97) and 24 hours (RR 1.36, 95% CI 0.80 to 2.34).One study (229 participants) compared olanzapine versus dexamethasone, reporting that olanzapine may reduce overall nausea (RR 1.73, 95% CI 1.37 to 2.18), overall vomiting (RR 1.27, 95% CI 1.10 to 1.48), delayed nausea (RR 1.66, 95% CI 1.33 to 2.08) and delayed vomiting (RR 1.25, 95% CI 1.07 to 1.45). AUTHORS' CONCLUSIONS There is moderate-quality evidence that oral olanzapine probably increases the likelihood of not being nauseous or vomiting during chemotherapy from 25% to 50% in adults with solid tumours, in addition to standard therapy, compared to placebo or no treatment. There is uncertainty whether it increases serious adverse events. It may increase the likelihood of other adverse events, probably increasing somnolence and fatigue. There is uncertainty about relative benefits and harms of 5 mg versus 10 mg.We identified only RCTs describing oral administration. The findings of this review cannot be extrapolated to provide evidence about the efficacy and safety of any injectable form (intravenous, intramuscular or subcutaneous) of olanzapine.

Randomized, Placebo-Controlled, Phase III Trial of Fosaprepitant, Ondansetron, Dexamethasone (FOND) Versus FOND Plus Olanzapine (FOND-O) for the Prevention of Chemotherapy-Induced Nausea and Vomiting in Patients with Hematologic Malignancies Receiving Highly Emetogenic Chemotherapy and Hematopoietic Cell Transplantation Regimens: The FOND-O Trial. Biol Blood Marrow Transplant 2018; 24:2065-2071.

Abstract
Evidence supports olanzapine for prophylaxis of chemotherapy-induced nausea/vomiting (CINV) for highly emetogenic chemotherapy; however, most studies focus on solid malignancies and single-day regimens. A randomized, double-blinded, placebo-controlled trial was conducted to compare the addition of olanzapine to triplet therapy (fosaprepitant, ondansetron, dexamethasone [FOND-O]) versus triplet therapy alone (FOND) in preventing CINV in hematology patients receiving single-day and multiple-day highly emetogenic chemotherapy and hematopoietic cell transplant (HCT) regimens (NCT02635984). The primary objective of this study was to compare complete response (CR; no emesis and minimal nausea, <25 mm on a 100-mm visual analog scale) during the overall assessment period (chemotherapy days plus 5 days after). Secondary objectives were the number of emesis, number of rescue medications, percent achieving minimal nausea, and percent achieving complete protection (CP; no emesis, rescue antiemetic, or significant nausea), all of which are reported as acute (chemotherapy days), delayed (5 days after chemotherapy), and overall phases. Olanzapine 10 mg or matching placebo were given on each chemotherapy day and 3 days after. Adults with hematologic malignancy receiving HCT regimens of melphalan, BEAM (carmustine, etoposide, cytarabine, melphalan), busulfan (Bu)/cyclophosphamide (Cy), Bu/fludarabine (Flu), Bu/melphalan, FluCy, FluCy-total body irradiation (TBI), etoposide-TBI, and ICE (ifosfamide, carboplatin, etoposide) or 7+3 chemotherapy regimens were included. An estimated 98 patients were required using alpha = .05 and 80% power. No significant differences existed in baseline characteristics between FOND-O (n = 51) and FOND (n = 50) arms. Mean duration of olanzapine was 7.7 days (range, 4 to 11). Discontinuation for possible adverse events occurred in 3 placebo and 0 olanzapine patients. CR was significantly higher for FOND-O in overall (55% versus 26%, P = .003) and delayed (60.8% versus 30%, P = .001) but not acute (P = .13) phases. Significantly more patients receiving FOND-O achieved no more than minimal nausea in overall (P = .001) and delayed phases (P = .0002), as well as fewer overall mean emesis counts (P = .005). CP rates were not different in any assessment phase (P ≥ .05 each). Within the HCT subgroup (n = 64), the CR, CP, and no significant nausea rates were significantly better for FONDO-O in overall and delayed phases (all P < .05). Analysis within the HCT subgroup revealed significant improvement in outcomes in delayed and overall phases with FOND-O in the autologous but not allogeneic cohort. Addition of olanzapine to an NK-1-based triplet antiemetic regimen significantly improved clinically relevant outcomes in the HCT population.

Abstract
For patients with cancer, the threat of chemotherapy-induced nausea and vomiting (CINV) can greatly influence treatment decisions and overall quality of life. Clinicians now have numerous effective antiemetic therapies to offer to patients, but selecting the optimal strategy can be complicated. Integration of current CINV guidelines, emerging data from recent clinical trials, and patient-specific risk factors can greatly improve antiemetic prophylaxis. Two challenging clinical scenarios are presented and discussed to provide insight on how to best approach these types of treatment decisions and apply recent advances in CINV prevention and management to patient care.

Abstract
Background The three-drug combination of a 5-hydroxytryptamine type 3 receptor antagonist, a neurokinin 1 receptor antagonist and dexamethasone is recommended for patients receiving highly emetogenic chemotherapy. However, standard antiemetic therapy is not completely effective in all patients. Methods We conducted an open-label, single-center, single-arm Phase II study to evaluate the efficacy of olanzapine in combination with standard antiemetic therapy in preventing chemotherapy-induced nausea and vomiting in patients with thoracic malignancy receiving their first cycle of cisplatin-based chemotherapy. Patients received 5 mg oral olanzapine on Days 1-5 in combination with standard antiemetic therapy. The primary endpoint was complete response (no vomiting and no use of rescue therapy) during the overall Phase (0-120 h post-chemotherapy). Results Twenty-three men and seven women were enrolled between May and October 2015. The median age was 64 years (range: 36-75 years). The most common chemotherapy regimen was 75 mg/m2 cisplatin and 500 mg/m2 pemetrexed, which was administered to 14 patients. Complete response rates in acute (0-24 h post-chemotherapy), delayed (24-120 h post-chemotherapy) and overall phases were 100%, 83% and 83% (90% confidence interval: 70-92%; 95% confidence interval: 66-93%), respectively. There were no Grade 3 or Grade 4 adverse events. Although four patients (13%) experienced Grade 1 somnolence, no patients discontinued olanzapine. Conclusions The addition of 5 mg oral olanzapine to standard antiemetic therapy demonstrates promising efficacy in preventing cisplatin-based chemotherapy-induced nausea and vomiting and an acceptable safety profile in patients with thoracic malignancy.

Abstract
PURPOSE The aim of this phase II study was to evaluate the efficacy and safety of two doses (10 and 5 mg) of olanzapine in combination with standard antiemetic treatment (aprepitant, palonosetron, and dexamethasone) for patients receiving highly emetogenic chemotherapy (HEC). METHODS A multi-institutional, double-blind, randomized phase II, dose-finding study of olanzapine was performed in patients with a malignant solid tumor who were receiving HEC with cisplatin (≥ 50 mg/m2). Patients were randomly assigned either olanzapine 10 or 5 mg orally on days 1-4, combined with standard antiemetic treatment. The primary endpoint was a complete response (CR; no emesis and no use of rescue medications) in the delayed phase (24-120 h after the start of cisplatin treatment). RESULTS 153 patients were randomized to the 10 mg group (n = 76) or the 5 mg group (n = 77). The CR rate in the delayed phase was 77.6% (80% CI: 70.3-83.8, P = 0.01) in the 10 mg group and 85.7% (80% CI: 79.2-90.7, P < 0.001) in the 5 mg group (P value for H 0: complete response rate ≤ 65%). The most common adverse event was somnolence, which had an incidence of 53.3 and 45.5% in the 10 and 5 mg olanzapine groups, respectively. CONCLUSIONS Both doses of 10 and 5 mg olanzapine provided a significant improvement in delayed emesis. A dose of 5 mg olanzapine was determined as the recommended dose for a further phase III study based on higher CR and lower somnolence rates. CLINICAL TRIAL INFORMATION UMIN000014214.
