Management of Trastuzumab Deruxtecan-related nausea and vomiting in real-world practice. Front Oncol 2024; 14:1374547. [PMID: 38529378 PMCID: PMC10961432 DOI: 10.3389/fonc.2024.1374547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 02/23/2024] [Indexed: 03/27/2024] Open
Abstract
Background Nausea and vomiting are common side effects of Trastuzumab Deruxtecan (T-DXd), but guidelines for optimal management were not initially available. This retrospective single-center study aimed at evaluating the efficacy of two antiemetic regimens in patients receiving T-DXd. Methods Data from metastatic breast cancer patients receiving T-DXd were collected. Two groups were defined: patients treated with 5-HT3 receptor antagonists (RA) ± dexamethasone (5-HT3-group) and patients treated with a fixed oral combination of netupitant (NK1RA) and palonosetron ± dexamethasone (NK1 group). Physicians preferentially offered the NK1 regimen to patients at higher risk of nausea and vomiting based on internal recommendations. Only nausea and vomiting during cycles 1 and 2 were considered. Comparisons of nausea and vomiting by the antiemetic prophylaxis group were assessed using chi-square. Results A total of 53 patients were included in the analysis. At cycle 1, 72% and 28% of patients received the 5-HT3 and NK1 prophylaxis, respectively. Overall, 58% reported nausea, with no differences between groups (58% vs. 60%; p = 0.832), but with a trend for lower grade in the NK1 group (33.3% G1; 26.7% G2) compared to the 5-HT3 group (23.7% G1; 31.6% G2; 2.6% G3). Vomiting was reported by 21% and 0% of patients in the 5-HT3 and the NK1 group, respectively (p = 0.054). Among the 15 patients in the 5-HT3 group with nausea at cycle 1 who escalated to NK1 at cycle 2, nausea decreased from 100% to 53% (p = 0.022) and vomiting decreased from 47% to 13% (p = 0.046). Conclusions The NK1 regimen improved vomiting control at cycle 1 and, when introduced at cycle 2, significantly improved both nausea and vomiting. The biased NK1 selection for higher-risk patients may have dampened the differences between groups at cycle 1. These findings support enhanced control of T-DXd-related nausea and vomiting with NK1RA.

Poon IO, Ajewole V, Braun UK. A Review of Olanzapine in the Treatment of Cancer Anorexia-Cachexia Syndrome. PHARMACY 2024; 12:34. [PMID: 38392941 PMCID: PMC10893239 DOI: 10.3390/pharmacy12010034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/25/2024] [Accepted: 02/04/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Cancer anorexia-cachexia syndrome (CAS) is a multifactorial condition that is highly prevalent in advanced cancer patients and associated with significant reduction in functional performance, reduction in quality of life, and increased mortality. Currently, no medications are approved for this indication. Recently, the American Society of Clinical Oncology (ASCO) released a rapid recommendation suggesting that low-dose olanzapine once daily may be used to treat cancer cachexia. Many questions still exist on how to use olanzapine for this indication in clinical practice. The objective of this review is to identify existing knowledge on the use of olanzapine for CAS. METHODS A comprehensive search was conducted to identify the primary literature that involved olanzapine for anorexia and cachexia in cancer patients between 2000 and 2023. RESULTS Seven articles were identified and are discussed here, including two randomized double-blinded placebo-controlled studies, one randomized comparative study, two prospective open-label studies, one retrospective chart review, and one case report. CONCLUSIONS Low dose olanzapine (2.5-5 mg once daily) may be useful in the treatment of CAS for increasing appetite, reducing nausea and vomiting, and promoting weight gain. Further large-scale multi-center randomized placebo-controlled studies will be needed to investigate the impact of olanzapine on weight change in CAS patients.

Abstract
PURPOSE This systematic review updates the MASCC/ESMO recommendations for high-emetic-risk chemotherapy (HEC) published in 2016-2017. HEC still includes cisplatin, carmustine, dacarbazine, mechlorethamine, streptozocin, and cyclophosphamide in doses of > 1500 mg/m2 and the combination of cyclophosphamide and an anthracycline (AC) in women with breast cancer. METHODS A systematic review report following the PRISMA guidelines of the literature from January 1, 2015, until February 1, 2023, was performed. PubMed (Ovid), Scopus (Google), and the Cochrane Database of Systematic Reviews were searched. The literature search was limited to randomized controlled trials, systematic reviews, and meta-analyses. RESULTS Forty-six new references were determined to be relevant. The main topics identified were (1) steroid-sparing regimens, (2) olanzapine-containing regimens, and (3) other issues such as comparisons of antiemetics of the same drug class, intravenous NK1 receptor antagonists, and potentially new antiemetics. Five updated recommendations are presented. CONCLUSION There is no need to prescribe steroids (dexamethasone) beyond day 1 after AC HEC, whereas a 4-day regimen is recommended in non-AC HEC. Olanzapine is now recommended as a fixed part of a four-drug prophylactic antiemetic regimen in both non-AC and AC HEC. No major differences between 5-HT3 receptor antagonists or between NK1 receptor antagonists were identified. No new antiemetic agents qualified for inclusion in the updated recommendations.

Abstract
INTRODUCTION Olanzapine use for chemotherapy-induced nausea and vomiting (CINV) in hematological malignancies, for multi-day chemotherapy, and with a steroid-sparing antiemetic strategy is poorly understood. This study investigated if olanzapine is associated with improved prevention of CINV when added to a steroid-sparing antiemetic regimen in patients with acute leukemia receiving intensive, moderately emetogenic, multi-day chemotherapy. METHODS This was a single-center, retrospective cohort study in patients with acute leukemia. Patients who received olanzapine for CINV prevention were compared to those who did not. All patients received a 5-HT3 antagonist. Adult patients receiving moderately emetogenic, multi-day, intensive chemotherapy for acute leukemia were included. Patients were excluded if they received steroids greater than physiological doses during the study period. The primary endpoint was the complete response of CINV (no emesis or rescue antiemetic usage). RESULTS This study included 58 patients, 12 patients received olanzapine and 46 patients were in the control group. Baseline demographics were similar. In the study population, 89.7% had acute myeloid leukemia, median age was 54 (interquartile range 42-63) years, 34.5% were female, 27.6% had prior CINV. Complete response of CINV was similar between groups, 4 (33.3%) and 15 (32.6%) patients in the olanzapine and control groups, respectively. Safety events were similar between groups. CONCLUSION Patients with acute leukemia receiving multi-day intensive chemotherapy are at high risk for CINV. The limited data in this study suggests that olanzapine use within a steroid-sparing antiemetic regimen was well tolerated and associated with similar incidence and severity of CINV compared to the control group.

Prevalence and predictors of long-delayed (> 120 h) chemotherapy-induced nausea and vomiting (CINV)-a systematic review and individual patient data meta-analysis. Support Care Cancer 2023; 31:505.

Abstract
INTRODUCTION Although there have been reports of chemotherapy-induced nausea and vomiting (CINV) beyond 120 h, its overall prevalence has not been systematically examined. The aim of this review and meta-analysis was to report on the prevalence of this long-delayed CINV. METHODS This review was registered on PROSPERO (CRD42022346963). PubMed (Medline), Embase, and Cochrane Central were searched from inception until August 2022. Articles were included if they reported on CINV > 120 h after initiation of the chemotherapy regimen and patients received a single-agent highly emetogenic (HEC) or moderately emetogenic (MEC) antineoplastic agent for 1 day alone or in combination with low/minimal emetogenic chemotherapy. For all eligible articles, individual study authors were contacted and requested to provide individual patient-level data of demographics, emetogenicity of chemotherapy regimens, and daily incidence of nausea and vomiting. Forward stepwise logistic regression identified predictors for the incident day's CINV based on prior day's CINV episodes, controlling for patient demographics, and stratified by regimen emetogenicity. RESULTS A total of 2048 patients from 2 studies were included in this individual patient data meta-analysis: 1333 patients (65%) received HEC and 715 (35%) received MEC. Among those receiving HEC, 325 (24%) experienced acute, 652 (49%) delayed, and 393 (31%) long-delayed nausea; 107 (8%) experienced acute, 179 (14%) delayed, and 79 (6%) long-delayed vomiting. Among those receiving MEC, 48 (7%) experienced acute, 272 (38%) delayed, and 167 (24%) long-delayed nausea; 12 (2%) experienced acute, 97 (14%) delayed, and 42 (6%) long-delayed vomiting. Nausea in the long-delayed phase was as severe as in the delayed phase. Patients experiencing nausea and vomiting on days 4 and 5 were at significant risk of experiencing long-delayed CINV. CONCLUSION While not as prevalent as delayed nausea and vomiting, long-delayed CINV affects a significant proportion of patients and severity is similar. Patients with delayed CINV, specifically on days 4-5, are at risk of experiencing long-delayed CINV.

Olanzapine for The Prevention of Nausea and Vomiting Caused by Chemoradiotherapy with High-Dose Cisplatin for Head and Neck Cancer. Yonago Acta Med 2023; 66:208-213. [PMID: 37229379 PMCID: PMC10203634 DOI: 10.33160/yam.2023.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 02/09/2023] [Indexed: 05/27/2023]
Abstract
Background Chemotherapy-induced nausea and vomiting (CINV) are the most common and distressing adverse events in patients receiving anticancer therapy. Radiotherapy also induces nausea and vomiting, so concurrent chemoradiotherapy-induced nausea and vomiting (CRINV) are significant problems for patients undergoing chemoradiotherapy. Conventionally, three-drug combination therapy with dexamethasone, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist, and neurokinin-1 (NK1) receptor antagonist has been used to prevent CRINV induced by concurrent chemoradiotherapy with cisplatin for patients with head and neck cancer (HNC). Nonetheless, CRINV still remains a problem. The effectiveness of adding olanzapine to prevent CINV has been reported, suggesting the efficacy of four-drug combination therapy for CRINV. However, its effectiveness has hardly been reported in patient receiving chemoradiotherapy for HNC. Methods A total of 109 patients with HNC who received concurrent chemoradiotherapy with cisplatin from April 2014 to March 2021 were included and divided into the following two groups according to antiemetic treatment regimen: the conventional group (Con group; n = 78) who received three-drug combination therapy and the olanzapine group (Olz group; Olz group, n = 31) who received four-drug combination therapy with olanzapine. Acute (0 to 24 h from cisplatin) and delayed (25 to 120 h from cisplatin) CRINV were then compared using the Common Terminology Criteria for Adverse Events. Results No significant difference in acute CRINV were observed between both groups (P = 0.5761, Fisher's exact test). However, the Olz group had a significantly lower incidence rate of delayed CRINV over Grade 3 compared to the Con group (P = 0.0318, Fisher's exact test). Conclusion Four-drug combination therapy with olanzapine was effective in suppressing delayed CRINV due to chemoradiotherapy with cisplatin for HNC.

Abstract
INTRODUCTION The antibody-drug conjugate trastuzumab deruxtecan (T-DXd) has led to a change in the clinical management of breast cancer. Nausea and vomiting are the most common adverse events of T-DXd, which cannot be completely alleviated by standard prophylactic regimens. Olanzapine is particularly effective in preventing delayed nausea caused by chemotherapy. In this study, we will evaluate the efficacy of olanzapine in managing persistent nausea and vomiting during T-DXd treatment. METHODS AND ANALYSIS The ERICA study is a multicentre, placebo-controlled, double-blind, randomised phase II study with the aim to evaluate the antiemetic effects of the prophylactic olanzapine (5 mg orally, on days 1-6) or placebo combined with a 1,5-hydroxytryptamine-3 (5-HT3)-receptor antagonist and dexamethasone in patients with human epidermal growth factor receptor 2-positive metastatic breast cancer undergoing T-DXd treatment. For a period of 22 days from the day of T-DXd treatment, patients will document their experience in an electronic symptom diary daily during observational periods. The primary endpoint is the complete response rate, defined as no vomiting and no rescue medications during the 'delayed phase' of 24-120 hours post-T-DXd administration. In addition, we define 120-504 hour as the 'persistent phase' and 0-504 hours as the 'overall phase' for secondary endpoint analysis. We have estimated that a total sample size of at least 156 patients is needed to allow a power of 80% at a one-sided significance level of 20% in this study. The target sample size is set to 166 to account for possible case exclusions. ETHICS AND DISSEMINATION The study protocol is approved by the West Japan Oncology Group protocol review committee and the SHOWA University Clinical Research Review Board. The study results will be presented at international conferences and published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER jRCTs031210410.
