Effect of Aprepitant for the Prevention of Chemotherapy-Induced Nausea and Vomiting in Women: A Randomized Clinical Trial

Low dose of dexamethasone combined with netupitant and palonosetron in preventing nausea and vomiting in breast cancer patients induced by anthracycline drugs

BACKGROUND

To study the effects of various courses of dexamethasone (DEX) combined with 5-HT3 receptor antagonists (RA) and NK-1 RA in suppressing high-grade nausea and vomiting (CINV) caused by anthracycline and cyclophosphamide chemotherapy regimens (AC or EC) in breast cancer (BC) patients.

PATIENTS AND METHODS

A prospective study was performed with 252 BC patients who received AC between January, 2019 and June, 2022 in our hospital. Patients were randomly separated into control Group (N = 130) who received DEX 12 mg on day 1 and 8 mg per dose on day 2-4 and observation group (N = 122) treated with DEX 5 mg per dose on days 1-4. The response was monitored. Primary study endpoint was complete resolution (CR) of patients nausea or vomiting; secondary study endpoints included acute CR and delayed CR; and complete control (CC), acute CC, delayed CC, and safety.

RESULTS

All patients underwent six rounds of chemotherapy, and no difference was found in the clinical data. CR of acute/delayed phase was (94.3%/88.5%, P > 0.05), (89.3%/90.8%, P > 0.05); total CR was (80.3%/81.5%, P > 0.05); CC was (56.6%/59.2%, P > 0.05), (64.8%/67.7%, P > 0.05); total CR was (48.4%/53.1%, P > 0.05).

CONCLUSIONS

The preventive antiemetic effects of NEPA, a fixed-dose combination of netupitant and palonosetron combined with DEX 5 mg per dose on days 1-4, can be similar to DEX 12 mg on day 1 and 8 mg per dose on days 2-4, low-dose hormone with better safety, which is beneficial.

A prospective randomized controlled clinical trial investigating the efficacy of low-dose olanzapine in preventing nausea and vomiting associated with oxaliplatin-based and irinotecan-based chemotherapy

OBJECTIVE

The aim of this study is to assess the clinical efficacy of a 5 mg dosage of olanzapine in preventing chemotherapy-induced nausea and vomiting (CINV) associated with moderately emetogenic chemotherapy (MEC) among female patients diagnosed with gastrointestinal tract tumors.

METHODS

Patients undergoing the oxaliplatin/irinotecan chemotherapy regimen were enrolled in this prospective controlled study. The olanzapine group received a 5 mg dosage of olanzapine along with palonosetron and dexamethasone, while the control group received a standard two-combination regimen consisting of dexamethasone and palonosetron. The primary endpoints included the total protection (TP) rates for the entire age group and the subgroup aged 60 years and above. Secondary endpoints encompassed the total protection rates during the acute and delayed phases within the two age brackets, as well as the total control (TC) rates and complete remission (CR) rates across all three phases (total, acute, and delayed). Additionally, the study involved the assessment of quality of life and the collection of adverse events associated with the interventions.

RESULTS

1) Regarding the primary endpoint, the total phase TP rates within both the entire age group and the age group exceeding 60 years demonstrated superiority in the olanzapine group when compared to the control group (66.7% vs 37.25%, P = 0.003; 68.8% vs 44.4%, P = 0.044). 2) In terms of secondary endpoints, the olanzapine group exhibited superior acute phase TP rates in both age brackets when compared to the control group (P < 0.05). The olanzapine group also demonstrated higher delayed-phase TP rates, TC rates across all three phases, and CR rates within the two age brackets, although the differences were not statistically significant (P > 0.05). Furthermore, the quality of life in the olanzapine group surpassed that of the control group for both age brackets (P < 0.05), characterized by enhanced appetite and a higher incidence of drowsiness in the patients treated with olanzapine when compared to those in the control group (P < 0.05).

CONCLUSION

Olanzapine can enhance CINV induced by MEC regimen in female patients across all age groups, including the elderly, and therefore improve the quality of life for these patients.

Herbal medicine for the prevention of chemotherapy-induced nausea and vomiting in patients with advanced colorectal cancer: A prospective randomized controlled trial

ETHNOPHARMACOLOGICAL RELEVANCE

Chinese herbal medicine is increasingly used as complementary therapy to manage nausea and vomiting in different cultures. One such herbal recipe is the Hezhong granules, which contain classical antiemetic formulations, and are commonly used to prevent chemotherapy-induced nausea and vomiting (CINV). Modern pharmacological studies have shown that the key components of Hezhong granules, including Pinellia ternata (Thunb.), Evodia rutaecarpa (Juss.), and Zingiber officinale exhibit significant antiemetic and antitumor properties. Despite this promising evidence, controlling CINV remains a significant challenge in cancer treatment. Moreover, there is a lack of scientifically designed clinical trials to validate the efficacy and safety of classical antiemetic formulas for CINV interventions.

AIMS OF THE STUDY

To investigate the efficacy and safety of Hezhong granules in preventing CINV in patients with advanced colorectal cancer (CRC).

METHODS

This study was conducted between October 2020 and February 2022 in 12 hospital wards in Southwest China. In this multicenter, randomized controlled trial, we enrolled patients with advanced CRC who received fluorouracil-based chemotherapy. The patients were randomly assigned in a 1:1 ratio to either the Hezhong granule group (receiving a 5-HT3-receptor antagonist, dexamethasone, and Hezhong granules) or the placebo group (receiving a 5-HT3-receptor antagonist, dexamethasone, and placebo) during the first and second courses of chemotherapy. A 5-day diary was provided to all patients. Acute and delayed CINV were defined as CINV occurring within 24 h or between 24 and 120 h after the start of treatment. The primary endpoints were complete response rate (CRR, defined as the proportion of patients without nausea/vomiting) and objective response rate (ORR, defined as the proportion of patients without nausea/vomiting plus mild nausea/vomiting) for both acute and delayed CINV. Secondary endpoints were the daily rates of CINV events and Functional Living Index-Emesis (FLIE). To identify the predictors of CINV, we conducted multivariate ordered logistic regression analysis. This study was registered with the Chinese Clinical Trial, number ChiCTR2100041643.

RESULTS

A total of 120 participants were randomly assigned, of whom 112 (56/56) completed two cycles and were included in the full analysis. In the acute phase, there were minor improvements in the Hezhong granule group, but there were no significant differences in the CRRs for nausea and vomiting (mean difference:10.7 %, P = 0.318, 0.324), while the ORRs increased by approximately 17.5 % (mean difference:16.1 %, P = 0.051; 17.9 %, P = 0.037, respectively). In the delayed phase, significant improvements of approximately 20 % were observed in both the CRRs (mean difference:19.6 %, P = 0.053; 21.4 %, P = 0.035) and ORRs (mean difference:17.9 %, P = 0.037, 0.043) for nausea and vomiting. Additionally, the daily rate of CINV events showed a mean difference of 19 % (P < 0.05). According to FLIE scores, approximately 70 % of patients who received Hezhong granules reported an improvement in their quality of life, with CINV symptoms having"no impact on daily life (NIDL)". No serious adverse events were attributed to herbal medicine.

CONCLUSIONS

Hezhong granules proved to be both effective and well-tolerated in preventing CINV in patients with advanced CRC, with notable benefits in preventing delayed CINV. These promising results set the stage for subsequent phase III clinical trials and experimental research on Hezhong Granules.

The Role of Small Molecules Containing Fluorine Atoms in Medicine and Imaging Applications

The fluorine atom possesses many intrinsic properties that can be beneficial when incorporated into small molecules. These properties include the atom's size, electronegativity, and ability to block metabolic oxidation sites. Substituents that feature fluorine and fluorine-containing groups are currently prevalent in drugs that lower cholesterol, relieve asthma, and treat anxiety disorders, as well as improve the chemical properties of various medications and imaging agents. The dye scaffolds (fluorescein/rhodamine, coumarin, BODIPY, carbocyanine, and squaraine dyes) reported will address the incorporation of the fluorine atom in the scaffold and the contribution it provides to its application as an imaging agent. It is also important to recognize radiolabeled fluorine atoms used for PET imaging in the early detection of diseases. This review will discuss the many benefits of incorporating fluorine atoms into small molecules and give examples of fluorinated molecules used in the pharmaceutical industry and imaging techniques.

2023 MASCC and ESMO guideline update for the prevention of chemotherapy- and radiotherapy-induced nausea and vomiting

•Nausea and vomiting are considered amongst the most troublesome adverse events for patients receiving antineoplastics. •The guideline covers emetic risk classification, prevention and management of treatment-induced nausea and vomiting. •The Consensus Committee consisted of 34 multidisciplinary, health care professionals and three patient advocates. •Recommendations are based on evidence-based data (level of evidence) and the authors’ collective expert opinion (grade). •All recommendations are for the first course of antineoplastic therapy; modifications may be needed in subsequent courses.

2023 updated MASCC/ESMO Consensus recommendations: Prevention of nausea and vomiting following moderately emetic risk antineoplastic agents

PURPOSE

Review the literature to update the MASCC guidelines from 2015 for controlling nausea and vomiting with systemic cancer treatment of moderate emetic potential.

METHODS

A systematic literature review was completed using Medline, Embase, and Scopus databases. The literature search was done from June 2015 to January 2023 of the management of antiemetic prophylaxis for anticancer therapy of moderate emetic potential.

RESULTS

Of 342 papers identified, 19 were relevant to update recommendations about managing antiemetic prophylaxis for systemic cancer treatment regimens of moderate emetic potential. Important practice changing updates include the use of emetic prophylaxis based on a triple combination of neurokinin (NK)1 receptor antagonist, 5-HT3 receptor antagonist, and steroids for patients undergoing carboplatin (AUC ≥ 5) and women < 50 years of age receiving oxaliplatin-based treatment. A double combination of 5-HT3 receptor antagonist and steroids remains the recommended prophylaxis for other MEC. Based on the data in the literature, it is recommended that the administration of steroids should be limited to day 1 in moderately emetogenic chemotherapy regimens, due to the demonstration of non-inferiority between the different regimens. More data is needed on the emetogenicity of new agents at moderate emetogenic risk. Of particular interest would be antiemetic studies with the agents sacituzumab-govitecan and trastuzumab-deruxtecan. Experience to date with these agents indicate an emetogenic potential comparable to carboplatin > AUC 5. Future studies should systematically include patient-related risk assessment in order to define the risk of emesis with MEC beyond the emetogenicity of the chemotherapy and improve the guidelines for new drugs.

CONCLUSION

This antiemetic MASCC-ESMO guideline update includes new recommendations considering individual risk factors and the optimization of supportive anti-emetic treatments.

Efficacy and safety of Aprepitant-containing triple therapy for the prevention and treatment of chemotherapy-induced nausea and vomiting: A meta-analysis

BACKGROUND

Most cancer patients suffer from the pain of chemotherapy-induced nausea and vomiting (CINV). This meta-analysis was performed to evaluate the efficacy and safety of a regimen consisting of aprepitant, dexamethasone, and 5-HT3 receptor antagonists in the prevention and treatment of CINV.

METHODS

A systematic literature search was conducted across multiple databases, including PubMed, EMbase, Cochrane Library, MEDLINE, CENTRAL, HEED, CNKI, Wanfang, and VIP, to identify randomized controlled trials (RCTs) investigating the use of triple therapy (aprepitant, 5-HT3 receptor antagonist, and dexamethasone) to prevent and treat CINV. Meta-analysis was performed using RevMan 5.4 and Stata17 software, employing either a fixed-effect or random-effect model based on statistical heterogeneity.

RESULTS

A meta-analysis of 23 randomized controlled trials (RCTs) involving 7956 patients was conducted. Efficacy: Results showed significantly improved complete responses (CRs) for CINV in the test group versus the control group in the overall, acute, and delayed phases. Furthermore, in the test group, substantial alleviation of nausea symptoms was observed in the delayed and overall phases but not in the acute phase. Safety: There was no statistically significant difference in the incidence of febrile neutropenia, diarrhea, anorexia, and headache between the 2 groups. The incidence of fatigue and hiccups in the test group was higher than that in the control group; however, the incidence of constipation was significantly lower.

CONCLUSIONS

Aprepitant-containing triple therapy is highly effective in the prevention and treatment of CINV, with reliable medication safety.

Fosaprepitant: current options to prevent chemotherapy-induced nausea and vomiting: A review

Background. Chemotherapy (CT) is a mainstay of treatment for malignant tumors. CT-induced nausea and vomiting are observed in 3090% of patients within 0120 h after moderate and highly emetogenic CT administration. These adverse events can severely impact the quality of treatment, daily life, and adherence to treatment, thus reducing the effectiveness of therapy and survival. Materials and methods. The author provides the results of a systematic review of research papers, including clinical studies, on the efficacy of the neurokinin-1 receptor antagonist fosaprepitant to prevent CT-induced nausea and vomiting. Data from the PubMed database were reviewed. Results. The prevention and treatment of CT-associated nausea and vomiting are vital during special therapy, including symptomatic therapy. International organizations recommend using a triple combination with antagonists of neurokinin-1 and 5-hydroxytryptamine-3 receptors and dexamethasone. According to the data obtained, the efficacy of fosaprepitant has been proven in delayed and general phases in several large, well-planned studies; the drug reduces the incidence of adverse events by 2.74.4 times compared with aprepitant. Conclusion. Fosaprepitant is an antagonist of neurokinin-1 receptors; when administered intravenously, it rapidly converts into aprepitant. When used as part of a triple combination with 5-hydroxytryptamine-3 receptor antagonists and dexamethasone in patients receiving moderate and highly emetogenic CT leads to a higher rate of complete response when controlling nausea and vomiting. In general, fosaprepitant is well tolerated.

Primary versus secondary antiemetic prophylaxis with NK1 receptor antagonists in patients affected by gastrointestinal malignancies and treated with a doublet or triplet combination regimen including oxaliplatin and/or irinotecan plus fluoropyrimidines: A propensity score matched analysis

Aim

The aim of the current study is to investigate the impact of primary compared to secondary chemotherapy-induced nausea and vomiting (CINV) prophylaxis with NK1 receptor antagonists (NK1-RA) in patients affected by gastrointestinal malignancies and treated with oxaliplatin- and/or irinotecan-based doublet or triplet regimens.

Study design and methods

Clinical data of patients affected by gastrointestinal malignancies, treated with an oxaliplatin and/or irinotecan-based doublet or triplet regimen as neo/adjuvant or advanced-line treatment, and who received NK1-RA as primary (from the first cycle of treatment) or secondary (after the onset of CINV with a previous regimen with 5HT3-RA and dexamethasone) prophylaxis for CINV, were retrospectively collected in an observational study involving 16 Italian centers. A propensity score matching was performed by taking into account the following stratification factors: sex (male vs. female), age (< vs. ≥70 years old), overweight (body mass index, BMI < vs. ≥25), underweight (BMI < vs. ≥19), disease spread (early vs. advanced/metastatic), tumor type (esophagogastric cancer vs. the rest, hepatobiliary tumor vs. the rest, colorectal cancer vs. the rest), type of NK1-RA used as primary/secondary prophylaxis (netupitant-palonosetron vs. fosaprepitant/aprepitant), concomitant use of opioids (yes vs. no), concomitant use of antidepressant/antipsychotic drugs (yes vs. no), Eastern Cooperative Oncology Group (ECOG) performance status at the start of NK1-RA treatment (0 vs. 1–2), and intensity of chemotherapy regimen (doublet vs. triplet).

Results

Among 409 patients included from January 2015 to January 2022 and eligible for analysis, 284 (69%) and 125 (31%) were treated with NK1-RA as primary and secondary antiemetic prophylaxis, respectively. After matching, primary NK1-RA use was not associated with higher rates of protection from emesis regardless the emesis phase (acute phase, p = 0.34; delayed phase, p = 0.14; overall phase, p = 0.80). On the other hand, a lower rate of relevant nausea (p = 0.02) and need for rescue antiemetic therapy (p = 0.000007) in the overall phase was found in primary NK1-RA users. Furthermore, a higher rate of both complete antiemetic response (p = 0.00001) and complete antiemetic protection (p = 0.00007) in the overall phase was more frequently observed in primary NK1-RA users. Finally, chemotherapy delays (p = 0.000009) and chemotherapy dose reductions (p = 0.0000006) were less frequently observed in primary NK1-RA users.

Conclusion

In patients affected by gastrointestinal malignancies, a primary CINV prophylaxis with NK1-RA, 5HT3-RA, and dexamethasone might be appropriate, particularly in those situations at higher risk of emesis and in which it is important to avoid dose delays and/or dose reductions, keeping a proper dose intensity of chemotherapy drugs.

Aprepitant plus palonosetron versus dexamethasone plus palonosetron in preventing chemotherapy-induced nausea and vomiting in patients with moderate-emetogenic chemotherapy: A randomized, open-label, phase 3 trial

Background

Despite significant progress in the prevention of chemotherapy-induced nausea and vomiting (CINV) by using dexamethasone combined with palonosetron for patients who received moderate-emetogenic chemotherapy (MEC), some of these patients still suffer from CINV. We evaluated whether aprepitant combined with palonosetron can improve the efficacy in the prevention of CINV in patients receiving MEC.

Methods

This was a single-centre, open-label, phase III, randomized controlled trial, which was done at the Sixth Affiliated Hospital of Sun Yat-sen University of China. The registered patients planned to receive mFOLFOX6 (oxaliplatin, leucovorin, and 5-fluorouracil) but had not received any chemotherapy previously. The patients were randomized in a 1:1 ratio to the aprepitant group (aprepitant 125 mg orally on day 1, 80 mg on day 2-3) and the dexamethasone group (dexamethasone 10 mg intravenously on day 1, 5 mg on days 2 and 3), both groups with palonosetron 0.25 mg intravenously on day 1. The primary endpoint was the proportion of patients who achieved a complete response (CR), defined as the absence of vomiting and no use of rescue medications in the overall phase (0-120 h). The primary outcome and safety were assessed in the modified intention-to-treat population, which excluded all patients who used estazolam within 24 h before registration and those who refused to keep a diary documenting the severity of nausea, frequency of vomiting, and the use of rescue therapy. This trial is registered with ClinicalTrials.gov, NCT02909478.

Findings

Between Sep 1, 2017, and Oct 23, 2019, 320 patients were enrolled, and 315 patients were evaluated. The proportion of patients who achieved CR was significantly higher with aprepitant than that noted with dexamethasone in the overall phase (88.8% vs. 74.2%; P = 0.0010; rate difference, RD 15%, 95% CI, 6% to 23%) and in the delayed phase (25-120 h), 90.6% vs. 75.5%, (P < 0.0001; RD 15%, 95%CI, 7% to 23%). No significant difference of CR rate was observed in the acute phase (0-24 h), 93.8% vs. 93.5%, (P = 0.94; RD 0%, 95% CI, -5% to 6%)). In the overall phase, the incidence of insomnia (P < 0.0010), dyspepsia (P = 0.038), and flushing (P = 0.0010) reported by the patients was significantly higher in the dexamethasone group than that in the aprepitant group.

Interpretation

Aprepitant combined with palonosetron is superior to dexamethasone combined with palonosetron in patients who received the MEC regimen mFOLFOX6 in terms of preventing CINV.

Pooled analysis of combination antiemetic therapy for chemotherapy-induced nausea and vomiting in patients with colorectal cancer treated with oxaliplatin-based chemotherapy of moderate emetic risk

BACKGROUND

Among patients with colorectal cancer (CRC) treated with oxaliplatin (L-OHP)-based chemotherapy, delayed chemotherapy-induced nausea and vomiting (CINV) have not been well controlled.

METHODS

We pooled data from two prospective observational studies in Japan and one phase III clinical trial to assess whether delayed CINV could be controlled with a combination of three antiemetics adding a neurokinin-1 receptor antagonist and identified individual risk factors, using an inverse probability treatment-weighted analysis.

RESULTS

A total of 661 patients were evaluable in this study (median age: 64 years; 391 male, and 270 female). 3 antiemetics controlled delayed nausea (33.18% vs. 42.25%; p = 0.0510) and vomiting (4.15% vs. 16.08%; p < 0.0001) better than with 2 antiemetics. Female and 2 antiemetics were risk factors for both delayed nausea (female-odds ratio [OR]: 1.918; 95% confidence interval [CI]: 1.292-2.848; p = 0.0012; 2 antiemetics-OR: 1.485; 95% CI: 1.000-2.204; p = 0.0498) and delayed vomiting (female-OR: 2.735; 95% CI: 1.410-5.304; p = 0.0029; 2 antiemetics-OR: 4.551; 95% CI: 2.116-9.785; p = 0.0001).

CONCLUSIONS

Identifying individual risk factors can facilitate personalized treatments for delayed CINV. We recommend a 3-antiemetic combination prophylaxis for CRC patients treated with L-OHP-based chemotherapy, especially for female patients.
