Preventing chemotherapy-induced nausea and vomiting in patients with lung cancer: efficacy of NEPA (netupitant-palonosetron), the first combination antiemetic

Melanocortin-4 receptor antagonist TCMCB07 alleviates chemotherapy-induced anorexia and weight loss in rats

Cancer patients undergoing chemotherapy often experience anorexia and weight loss that substantially deteriorates overall health, reduces treatment tolerance and quality of life, and worsens oncologic outcomes. There are currently few effective therapeutic options to mitigate these side effects. The central melanocortin system, which plays a pivotal role in regulating appetite and energy homeostasis, presents a logical target for treating anorexia and weight loss. In this preclinical study, we evaluated the efficacy of TCMCB07, a synthetic antagonist of the melanocortin-4 receptor, in mitigating anorexia and weight loss in several rat models of chemotherapy: cisplatin, 5-fluorouracil, cyclophosphamide, vincristine, doxorubicin, and a combination of irinotecan and 5-fluorouracil. Our results indicate that peripheral administration of TCMCB07 improved appetite, stabilized body weight, preserved fat and heart mass, and slightly protected lean mass after multiple cycles of chemotherapy. Furthermore, combining TCMCB07 with a growth differentiation factor 15 antibody enhanced treatment effectiveness. Similar effects from TCMCB07 treatment were observed in a rat tumor model following combination chemotherapy. No notable adverse effects nor increased chemotherapy-related toxicities were observed with TCMCB07 treatment. These findings suggest that peripheral administration of TCMCB07 holds promise as a therapeutic approach for alleviating chemotherapy-induced anorexia and weight loss, potentially benefiting numerous patients undergoing chemotherapy.

Integrating nutrition, physical exercise, psychosocial support and antiemetic drugs into CINV management: The road to success

Over the years, advancements in antiemetic drugs have improved chemotherapy-induced nausea and vomiting (CINV) control. However, despite the antiemetics therapies, in a relevant number of adult patients (∼30 %), CINV is still persistent, leading to several complications, such as electrolyte imbalances, anorexia, and treatment discontinuation. Supportive care interventions have gained credibility in cancer care, helping to improve patients' psycho-physical condition, quality of life, and managing symptoms, including CINV. Physical exercise and tailored nutritional counseling have demonstrated benefits in reducing the severity of nausea and vomiting. Psychological intervention has been postulated as a key approach in controlling anticipatory nausea/vomiting, as well as acupuncture/acupressure has been shown to decrease nausea and vomiting after chemotherapy treatments. In the current review, we aim to provide a clinical update on current prophylactic and delayed antiemetic guidelines for CINV and an overview of the non-pharmacological interventions tested for alleviating CINV in patients with cancer.

Neiguan (PC6) acupoint stimulation for preventing chemotherapy-induced nausea and vomiting: a cost-effective supplement in guideline-inconsistent chemotherapy-induced nausea and vomiting prophylaxis subgroup

OBJECTIVE

To assess the efficacy and safety of Neiguan (PC6) acupoint acustimulation in preventing chemotherapy-induced nausea and vomiting (CINV), especially for patients with guideline-inconsistent CINV prophylaxis (GICP) due to personal reasons METHODS: From January 2021 to December 2021, 373 patients suffered from solid malignancy were recruited according to the inclusion criteria. Complete response (no emesis and no rescue medication use) rate during the overall phase (0-120 h of each chemo-cycle) was the primary assessment of CINV control. The Functional Living Index-Emesis (FLIE) questionnaire was investigated among these patients as a secondary 'quality of life' objective to assess the impact of CINV on patients' daily life by recording score of nausea and vomiting.

RESULTS

With acustimulation of Neiguan (PC6) acupuncture point through a portable, noninvasive and user-friendly device, in terms of complete response rate and scores in nausea/vomiting by FLIE questionnaire, patients achieve a better outcome in highly emetogenic chemotherapy (HEC) induced CINV, especially GICP subgroup. Meanwhile, analysis also demonstrated this tendency existed in other patients with HEC/GCCP (guideline consistent CINV prophylaxis) and moderate emetogenic chemotherapy, although the difference was not significant.

CONCLUSION

Considering advantages of Neiguan (PC6) acustimulation such as noninvasive, covered by medical insurance and few side effects, we believe it would be an ideal auxiliary tool in CINV control, especially in patients who receive highly emetogenic chemo-protocol and are reluctant to GCCP for economic reasons.

2023 updated MASCC/ESMO consensus recommendations: prevention of nausea and vomiting following high-emetic-risk antineoplastic agents

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.

Effect of Nursing Method of Psychological Intervention Combined with Health Education on Lung Cancer Patients Undergoing Chemotherapy

At present, lung cancer has become clinically the malignant tumor with the highest incidence and mortality rate in China. Smoking, environmental pollution, infection, etc., are closely related to lung cancer. To investigate the effect of the nursing method of psychological intervention combined with health education on lung cancer patients undergoing chemotherapy, 70 lung cancer patients who received chemotherapy in our hospital from June 2017 to June 2020 were selected and randomly divided into a routine intervention group (n = 35) and a combined intervention group (n = 35). Patients in the two groups had the same chemotherapy method and medication. The routine intervention group received the routine nursing intervention, while on this basis, the combined intervention group received psychological intervention combined with health education. After 6-week nursing, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score, cancer pain score before and after nursing, improvement of respiratory function before and after nursing, sleep quality score, quality of life score, and nursing satisfaction were analyzed. Through nursing intervention, the quality of life indexes such as physiological, physical, social, emotional, and other indexes in the combined intervention group were significantly better than those in the routine intervention group, with statistical differences (P < 0.01). The nursing satisfaction in the combined intervention group was significantly better than that in the routine intervention group, with statistical significance (χ² = 8.9342, P < 0.05). The psychological intervention combined with health education for lung cancer patients undergoing chemotherapy can effectively alleviate anxiety and depression, increase confidence in treatment, reduce pain and significantly improve sleep quality, respiratory function, quality of life, and nursing satisfaction.

Netupitant/Palonosetron: A Review in Chemotherapy-Induced Nausea and Vomiting

Netupitant/palonosetron (NEPA; Akynzeo^®), available in oral and intravenous (IV) formulations, is a fixed-dose combination of the neurokinin 1 (NK1) receptor antagonist netupitant (or the prodrug, fosnetupitant, in the IV formulation) and the second-generation serotonin 3 (5-HT₃) receptor antagonist palonosetron. Administered as a single dose, (fos)netupitant/palonosetron (in combination with dexamethasone) is indicated for the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in adults. In clinical trials, (fos)netupitant/palonosetron plus dexamethasone was associated with high complete response rates (no emesis and no rescue medication) in the acute, delayed and overall phases in patients receiving highly or moderately emetogenic chemotherapy, with efficacy maintained over multiple cycles. Further, oral netupitant/palonosetron was found to be superior to palonosetron and non-inferior to aprepitant plus granisetron in preventing CINV in individual trials. Both the oral and IV formulations of the drug combination are well tolerated. The fixed-dose combination is concordant with guideline recommendations and provides a simple and convenient option for prophylaxis against acute and delayed CINV in patients receiving highly or moderately emetogenic chemotherapy.

Evaluation of clinical outcomes and efficacy of palonosetron and granisetron in combination with dexamethasone in Egyptian patients receiving highly emetogenic chemotherapy

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) is considered one of the most serious adverse events affecting chemotherapy-receiving cancer patients. It dramatically affects their food intake, nutritional status and more importantly their quality of life. We can observe CINV in highly emetogenic chemotherapy (HEC) such as adriamycin-cyclophosphamide combination (AC) in breast cancer patients and cisplatin-based regimens in other cancer types. This study aimed to evaluate the antiemetic efficacy of palonosetron (PALO) over granisetron (GRA) in combination with dexamethasone for multiple highly emetogenic chemotherapy drugs (HEC), especially in chemotherapy regimens in Egyptian breast cancer patients and cisplatin-based regimens in other diseases.

PATIENTS AND METHODS

An open-label randomized trial was carried out, including 115 patients receiving at least four cycles of highly emetogenic chemotherapy regimens. All patients received dexamethasone in combination with the 5-HT3 receptor antagonist. We recorded patients' clinical and biochemical characteristics and withdraw blood samples to monitor serum substance P and serotonin in correlation with chemotherapy-induced nausea and vomiting (CINV). We use the MASCC antiemetic tool in the acute phase (0-24 hr) and delayed phase (24-120 h) to evaluate patient outcomes in both stages after each chemotherapy cycle.

RESULTS

In (PALO) group, only 7.84% of patients showed acute vomiting, and 11.76% showed acute nausea, whereas 43.75% of patients showed acute vomiting and 89.06% showed acute nausea in (GRA) group (P < 0.0001). For delayed CINV, 23.53% of patients showed delayed vomiting, and 47.06% showed delayed nausea in the (PALO) group, while 82.81% of patients showed delayed emesis, and 92.19% showed delayed nausea in (GRA) group (P < 0.0001). The study showed that PALO is a cost-effective choice when compared to GRA in CINV prevention as 45.10% of patients in (PALO) required additional rescue medications (Domperidone 10 mg orally three times per day plus Trimebutine 200 mg orally three times per week both for 5 days), while 95.24% in the (GRA) group used the same medications. Adverse events of both antiemetic drugs (PALO and GRA) include headaches and constipation and QTc prolongation reports, mostly mild to moderate, with relatively low rates among the two groups.

CONCLUSION

Palonosetron, combined with dexamethasone, is more effective than granisetron and dexamethasone combination against both acute and delayed emesis induced by highly emetogenic chemotherapy (HEC) cisplatin-based protocols and the combination of cyclophosphamide and anthracyclines (AC). Medical team members should make more efforts, especially clinical pharmacy personnel, to monitor medications' effectiveness and help the medical team achieve a suitable and reliable care plan.

Symptom trajectories during chemotherapy in patients with non-small cell lung cancer (NSCLC) and the function of prolonging low dose dexamethasone in promoting enhanced recovery after chemotherapy

Background

Lung cancer, mainly non‐small cell lung cancer (NSCLC), is one of the leading causes of death worldwide. Currently, chemotherapy is still the most significant treatment strategy for NSCLC. However, scant attention has been paid in previous studies to those patients who often experience various symptoms and discomfort during chemotherapy treatment cycles.

Methods

This study included 127 NSCLC patients who completed an EORTC QLQ‐C30 questionnaire and specifically designed symptom diary. Chi‐square test, factor analysis, Pearson correlation coefficient and hierarchical cluster analysis were used to perform multivariate analysis.

Results

We identified the top five most‐frequent symptoms within the chemotherapy cycle which included fatigue, insomnia, cough and sputum, appetite loss and hypodipsia. These symptoms were at a moderate level on chemotherapy treatment days 3–7, and were then reduced to a stable and lower level in the following two weeks. A statistically significant difference in adverse events (AEs) was found between 54 patients who received dexamethasone (treatment group) and the control group: fatigue (risk ratio [RR]: 1.48; 95% confidence interval [CI]: 1.120–1.961; p = 0.006), insomnia (RR: 1.34; 95% CI: 1.016–1.778; p = 0.038), cough and sputum (RR: 2.00; 95% CI: 1.484–2.695; p < 0.001), appetite loss (RR: 1.28; 95% CI: 0.959–1.696; p = 0.095). In total, 62 patients completed the EORTC QLQ‐C30 scale. The functioning scales of the treatment group were higher than the control population within positive effect sizes (ES: 0.1–0.8). Apart from diarrhea scales, most symptom scales were lower than the control group within negative effect sizes (ES: 0.1–0.9).

Conclusions

In this study we identified the top five most frequent post‐chemotherapy AEs in a chemotherapy treatment cycle and found that dexamethasone was well tolerated by NSCLC patients who received platinum‐based chemotherapy and substantially alleviated the symptom burden and improved the health‐related quality of life (HRQOL) of patients.

GDF-15 Neutralization Alleviates Platinum-Based Chemotherapy-Induced Emesis, Anorexia, and Weight Loss in Mice and Nonhuman Primates

Platinum-based cancer therapy is restricted by dose-limiting side effects and is associated with elevation of growth differentiation factor 15 (GDF-15). But whether this elevation contributes to such side effects has been unclear. Here, we explored the effects of GDF-15 blockade on platinum-based chemotherapy-induced emesis, anorexia, and weight loss in mice and/or nonhuman primate models. We found that circulating GDF-15 is higher in subjects with cancer receiving platinum-based chemotherapy and is positively associated with weight loss in colorectal cancer (NCT00609622). Further, chemotherapy agents associated with high clinical emetic score induce circulating GDF-15 and weight loss in mice. Platinum-based treatment-induced anorexia and weight loss are attenuated in GDF-15 knockout mice, while GDF-15 neutralization with the monoclonal antibody mAB1 improves survival. In nonhuman primates, mAB1 treatment attenuates anorexia and emesis. These results suggest that GDF-15 neutralization is a potential therapeutic approach to alleviate chemotherapy-induced side effects and improve the quality of life.

Gingerol inhibits cisplatin-induced acute and delayed emesis in rats and minks by regulating the central and peripheral 5-HT, SP, and DA systems

Abstract

Gingerol, a biologically active component in ginger, has shown antiemetic properties. Our study aimed to explore the underlying mechanisms of gingerol on protecting rats and minks from chemotherapy-induced nausea and vomiting. The preventive impact of gingerol was evaluated in the pica model of rats and the vomiting model of minks induced by cisplatin at every 6 h continuously for a duration of 72 h. Animals were arbitrarily separated into blank control group, simple gingerol control group, cisplatin control group, cisplatin + metoclopramide group, cisplatin + three different doses gingerol group (low-dose; middle-dose; high-dose). The area postrema as well as ileum damage were assessed using H&E stain. The levels of 5-TH, 5-HT₃ receptor, TPH, SERT, SP, NK₁ receptor, PPT, NEP, DA, D2R, TH, and DAT were determined using immunohistochemistry or qRT-PCR in rats and minks. All indicators were measured in the area postrema along with ileum. The kaolin intake by rats and the incidence of CINV of minks were significantly decreased after pretreatment with gingerol in a dosage-dependent way for the duration of 0–24-h and 24–72-h. Gingerol markedly decreased the levels of 5-TH, 5-HT₃ receptor, TPH, SP, NK₁ receptor, PPT, DA, D2R, TH, alleviated area postrema as well as ileum damage, and increased the accumulation of SERT, NEP, DAT in the area postrema along with ileum of rats and minks. Gingerol alleviates cisplatin-induced kaolin intake of rats and emesis of minks possibly by regulating central and peripheral 5-HT system, SP system and DA system.
