A dose-finding randomized Phase II study of oral netupitant in combination with palonosetron .75 mg intravenous for the prevention of chemotherapy-induced nausea and vomiting in Japanese patients receiving highly emetogenic chemotherapy

Discovering different acupoint combinations of manual or electro-acupuncture to treat chemotherapy-induced nausea and vomiting based on the complex networks analysis

OBJECTIVES

The aim of this research was to find the acupoint combinations of manual and electro-acupuncture to treat chemotherapy-induced nausea and vomiting via the complex networks analysis.

METHODS

We conducted searches using PubMed, ScienceDirect, MEDLINE, Ovid, spring, Wiley, EMBASE, the Chinese biomedicine database, VIP information network, and China National Knowledge Infrastructure from the establishment of the databases to the August, 2023. Information about titles, journals, interventions, and main acupoints was extracted using the self-established "acupoint for prevention CINV data base" powered by EpiData. According to the level of literature evidence and sample size, the clinical trials and weights of the outcome indicators including nausea/vomiting efficiency were combined. After identifying articles, literature processing and complex network analysis were conducted. The degree distribution of each node, the probability distribution of node degree, the node clustering coefficient, and the distance matrix are calculated by software.

RESULTS

Of the 4001 screened publications, 489 were eligible after careful selection. Our result showed the acupoints ST36 and PC6 were the most common combination acupoints in both electro and manual acupuncture. In terms of efficiency, ST36, PC6, and CV12 are significantly effective acupoints for manual acupuncture, and the PC6 and ST36 are effective acupoint for electro-acupuncture.

CONCLUSIONS

We found that the near-far collocation method has been commonly used for different types of acupuncture treatment in CINV. Zhongwan, Shangwan, and Liangmen have been mainly used as local acupoints, while Neiguan, Hegu, Quchi, Zusanli, Gongsun, TaiChong, and Neiguan have been mainly used as distal acupoints. From the effect analysis, acupuncture treatment of nausea manual acupuncture effect is better; acupuncture treatment of vomiting or electro-acupuncture effect is better.

Acupuncture therapy for preventing the nausea and vomiting following high emetic risk chemotherapy: A protocol for systematic review and Bayesian Network meta-analysis

BACKGROUND

Nausea and vomiting are the most common complications after chemotherapy, which cannot be completely controlled even with commonly prescribed antiemetic drugs, particularly in patients receiving highly emetogenic chemotherapy Acupuncture therapy is an effective replacement method for chemotherapy-induced nausea and vomiting (CINV), which effectiveness and safety have been observed by many clinicians. However, different acupuncture treatments have various effectiveness. Based on enough clinical researches, the study aims to uses Bayesian network meta-analysis (NMA) to evaluate the effectiveness of different acupuncture therapies used for preventing CINV.

METHODS

Authors will search PubMed/Medline, Cochrane library, Web of Science, Ebsco, Ovid/Embase, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine from setup time to July 2020. All randomized control trails meet the standard will be included. Quality evaluation of included studies will be implemented with Cochrane risk-of-bias tool. STATA 14.0 will be used to perform pairwise meta-analysis. Addis 1.16.8 (University Medical Center Groningen (UMCG), Groningen, NL) and OpenBUGS 3.2.3 (Medical Research Council (MRC), London, UK) will be used to conduct NMA.

RESULTS

The results of this review will generate a comprehensive review of current evidence and be published on a peer-reviewed journal.

CONCLUSION

The result of this systematic review and Bayesian NMA may offer better options for patients in relieving CINV.Systematic review registration number: INPLASY202070070.

Prevention of chemotherapy-induced nausea and vomiting with acupuncture: A protocol for systematic review and meta-analysis

BACKGROUND

Nausea and vomiting are the most common complications following chemotherapy and usually lead to decreased quality of life. Acupuncture therapy is an effective method for chemotherapy-induced nausea and vomiting (CINV), the effects and safety have been observed by many clinicians and demonstrated in a systematic review, which was included in the Cochrane Library in 2014. After several years, new studies have occurred and an updated systematic evaluation is needed. This protocol describes a method for performing a systematic review and meta-analysis to further evaluate the beneficial effects and safety of acupuncture for CINV.

METHODS

A searching strategy will be carried out mainly in eight databases in English and Chinese, Cochrane Central Register of Controlled Trials, PubMed, Embase, China National Knowledge Infrastructure, the Chinese Scientific Journal Database, the Wanfang database, China Doctoral Dissertations Full-text Database, and China Master's Theses Full-text Database. Only randomized controlled trials related to acupuncture for CINV will be included to enhance the effectiveness. The effective percentage will be used as primary outcome. Changes in the symptoms of nausea and vomiting, like severity, duration, and frequency as well as quality of life will be assessed as secondary outcome. Side effects and adverse events will be used as safety evaluations. To ensure the quality of the systematic evaluation, study selection, data extraction, and quality assessment will be independently performed by 2 authors, and the third author will deal with any disagreement. The Review Manager V.5.3.3 s will be used to perform the data synthesis and subgroup analysis.

RESULTS

There are additional studies, further explanations and more subgroup analyses compared with the previous systematic analysis to determine the effects and safety of acupuncture for CINV.

CONCLUSION

The result of this systematic review may offer clinicians stronger evidence to assist patient in relieving CINV.

Multicenter, placebo-controlled, double-blind, randomized study of fosnetupitant in combination with palonosetron for the prevention of chemotherapy-induced nausea and vomiting in patients receiving highly emetogenic chemotherapy

Background

The current randomized, double‐blind, phase 2 study assessed the efficacy and safety profile of a single intravenous administration of fosnetupitant, a neurokinin 1 receptor antagonist prodrug, for the prevention of chemotherapy‐induced nausea and vomiting in Japanese patients receiving cisplatin‐based chemotherapy.

Methods

Patients scheduled to receive cisplatin (at a dose of ≥70 mg/m²)‐based regimens were randomly assigned to receive fosnetupitant at a dose of 81 mg or 235 mg or placebo in combination with palonosetron at a dose of 0.75 mg and dexamethasone. The primary endpoint was complete response (CR; no vomiting and no rescue medication) during the overall phase (0‐120 hours). The overall CR rate was compared between each dose of fosnetupitant and the placebo group adjusting for the stratification factors of sex and age class (age <55 years vs age ≥55 years). Safety was assessed, with special attention given to events that potentially were suggestive of infusion site reactions.

Results

A total of 594 patients were randomized. Of these, 194 patients, 195 patients, and 195 patients, respectively, in the placebo and fosnetupitant 81‐mg and 235‐mg dose groups were evaluable for efficacy. The overall CR rate was 54.7% for the placebo group, 63.8% for the fosnetupitant 81‐mg dose group (adjusted difference, 9.1%; 95% CI, ‐0.4% to 18.6% [P = .061]), and 76.8% for the fosnetupitant 235‐mg dose group (adjusted difference, 22.0%; 97.5% CI, 11.7% to 32.3% [P < .001]). Safety profiles were comparable between the 3 groups. The incidence of infusion site reactions related to fosnetupitant was ≤1% in each dose group.

Conclusions

Fosnetupitant at a dose of 235 mg provided superior prevention of chemotherapy‐induced nausea and vomiting among patients receiving cisplatin‐based chemotherapy compared with the control group, and with a satisfactory safety profile.

Fosnetupitant at a dose of 235 mg combined with palonosetron and dexamethasone was demonstrated to be effective in the prevention of emesis during the first 0 to 120 hours after the administration of cisplatin. The results of the current study suggest that fosnetupitant at a dose of 235 mg also may improve the percentage of patients with no nausea in the delayed phase (24 ‐ 120 hours after cisplatin administration), which is an unmet medical need of patients with cancer who are receiving chemotherapy.

Effect of acupoint therapies on chemotherapy-induced nausea and vomiting: A systematic review protocol

BACKGROUND

Patients suffering from chemotherapy-induced nausea and vomiting (CINV) might have negative adherence of treatment. Acupoint therapies, including acupuncture, acupressure, acupoints injection, massage, and moxibustion, are safe medical procedures with minimal side effects for CINV, but studies about overall safety and effectiveness of acupoint therapies have not been scientifically and methodically evaluated in recent years. Evaluating the overall safety and effectiveness of acupoint therapies in patients with CINV is the purpose of this review.

METHODS AND ANALYSIS

Relevant randomized controlled trials (RCTSs) are being searched in the following electronic databases: PubMed, Cochrane Library, Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP database), Wanfang Data Knowledge Service Platform, and Chinese Biomedical Literature Database (CBM). We will also attempt to obtain the unpublished academic data by contacting the colleague, professor, or Institute of Traditional Chinese Medicine. The RCTs of the acupoint therapies for CINV patients will be searched in the databases from inception to July 2019. The primary outcomes are defined as severity, duration and frequency of nausea or vomiting, or both. The secondary outcomes are defined as any adverse events and quality of life. Performing the meta-analysis by using RevMan version 5 software. Mean difference (MD) or standardized mean difference (SMD) will express the continuous variables, while relative risk (RR) will express the categorical variables.

RESULTS

The results of this review will provide a high-quality synthesis to evaluate the effectiveness and safety of acupoint therapies for CINV.

CONCLUSION

This review will provide evidence to estimate whether acupoint therapies are effective interventions for CINV.

DISSEMINATION

Evidence whether acupoint therapies are effective interventions for CINV will be provided by this systematic review. This knowledge will recommend better acupoint therapies and selections of acupoints which might be helpful in treating CINV. The findings of this systematic review will be disseminated via various forms of presentation and publication of the data in a journal or electronic databases.
