The use of aprepitant for the prevention of postoperative nausea and vomiting in endoscopic transsphenoidal pituitary surgery. Int Forum Allergy Rhinol 2023; 13:2180-2186. [PMID: 37302141 DOI: 10.1002/alr.23208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/06/2023] [Accepted: 06/07/2023] [Indexed: 06/13/2023]
Abstract
BACKGROUND Postoperative nausea and vomiting (PONV) are adverse effects after surgery, which may increase the risk of complications. Aprepitant is a neurokinin-1 receptor blocker and has been shown to reduce chemotherapy-related nausea and vomiting and PONV. However, its role in endoscopic skull base surgery remains unclear. The purpose of this study was to evaluate the effect of aprepitant in reducing PONV in endoscopic transsphenoidal (TSA) pituitary surgery. METHODS A retrospective chart review between July 2021 and January 2023 of 127 consecutive patients who underwent TSA was performed at a tertiary academic institution. Patients were divided into 2 groups based on preoperative aprepitant use. Two groups were matched based on known risk factors of PONV (age, sex, nonsmoking, and history of PONV). The primary outcome was the incidence of PONV. Secondary outcome measures included the number of anti-emetic use, length of stay, and postoperative cererebrospinal fluid (CSF) leak. RESULTS After matching, 48 patients were included in each group. The aprepitant group demonstrated a significantly lower incidence of vomiting than the non-aprepitant group (2.1% vs 22.9%, p = 0.002). The number of nausea episodes and anti-emetic use decreased with aprepitant use (p < 0.05). There was no difference in the incidence of nausea, length of stay, or postoperative CSF leak. Multivariate analysis demonstrated that aprepitant decreased the incidence of postoperative vomiting with odds ratio of 0.107. CONCLUSION Aprepitant may serve as a useful preoperative treatment to reduce PONV in patients undergoing TSA. Further studies are needed to evaluate its impact in other arenas of endoscopic skull base surgery.

Economic Value of Fosaprepitant-Containing Regimen in the Prevention of Chemotherapy-Induced Nausea and Vomiting in China: Cost-Effectiveness and Budget Impact Analysis. Front Public Health 2022; 10:913129. [PMID: 35903377 PMCID: PMC9315060 DOI: 10.3389/fpubh.2022.913129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 06/20/2022] [Indexed: 12/24/2022] Open
Abstract
Objective The purpose of this study was to evaluate the cost-effectiveness and budget impact of fosaprepitant (FosAPR)-containing regimen for the prevention of chemotherapy-induced nausea and vomiting (CINV) among patients receiving high emetogenic chemotherapy (HEC) from the Chinese payer's perspective. Methods A decision tree model was established to measure the 5-day costs and health outcomes between the APR-containing regimen (aprepitant, granisetron, and dexamethasone) and FosAPR-containing regimen (fosaprepitant, granisetron, and dexamethasone). Clinical data were derived from a randomized, double-blind controlled trial on Chinese inpatients who received HEC. Quality-adjusted life-years (QALYs) were used to estimate the utility outcomes and the incremental cost-effectiveness ratio (ICER) was calculated to assess the economics of FosAPR. A static budget impact model was developed to assess the impact of FosAPR as a new addition to the National Reimbursement Drug List (NRDL) on the medical insurance fund within 3 years in Nanjing, China. Results Compared with APR, FosAPR had a mean health-care savings of ¥121.56 but got a reduction of 0.0001815 QALY, resulting in an ICER of ¥669926.19 per QALY. Deterministic sensitivity analysis revealed that the cost of APR was the most influential factor to the ICER. The cost of FosAPR and the complete control rate of the delayed period also had a high impact on the results. According to the probabilistic analysis, the acceptability of FosAPR was more than 80% when the Chinese willingness-to-pay (WTP) was ¥215,999. FosAPR would lead to a 3-year medical insurance payment increase of ¥1.84 million compared with ¥1.49 million before FosAPR entered NRDL in Nanjing. The total budget increased with a cumulative cost of ¥694,829 and covered an additional 341 patients who benefited from FosAPR in Nanjing. Deterministic sensitivity analysis showed that the model of budget impact analysis was stable. Conclusion FosAPR had a similar treatment effect to APR but was cost-effective in China at the current WTP threshold. The total budget of medical insurance payments of Nanjing slightly increased year by year after the inclusion of FosAPR. Its inclusion in the NRDL would be acceptable and also expand the coverage of patients who benefited from FosAPR.

Cost-effectiveness analysis of NEPA, a fixed-dose combination of netupitant and palonosetron, for the prevention of highly emetogenic chemotherapy-induced nausea and vomiting: an international perspective. Support Care Cancer 2022; 30:9307-9315. [PMID: 36074186 PMCID: PMC9633536 DOI: 10.1007/s00520-022-07339-1] [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: 12/13/2021] [Accepted: 08/13/2022] [Indexed: 01/05/2023]
Abstract
PURPOSE The aim of this study was to assess the cost-effectiveness of NEPA, a fixed-dose combination of oral netupitant (300 mg) and palonosetron (0.5 mg), compared to available treatments in Spain after aprepitant generic introduction in the market, and to discuss results in previously performed analyses in different wordwide settings. METHODS A Markov model including three health states, complete protection, complete response at best and incomplete response, was used to evaluate the cost-effectiveness of NEPA versus common treatment options in Spain during 5 days after chemotherapy. Incremental costs including treatment costs and treatment failure management cost as well as incremental effects including quality adjusted life days (QALDs) and emesis-free days were compared between NEPA and the comparator arms. The primary outcomes were cost per avoided emetic event and cost per QALDs gained. RESULTS NEPA was dominant (more effective and less costly) against aprepitant combined with palonosetron, and fosaprepitant combined with granisetron, while, compared to generic aprepitant plus ondansetron, NEPA showed an incremental cost per avoided emetic event of €33 and cost per QALD gained of €125. CONCLUSION By most evaluations, NEPA is a dominant or cost-effective treatment alternative to current antiemetic standards of care in Spain during the first 5 days of chemotherapy treatment in cancer patients, despite the introduction of generics. These results are in line with previously reported analyses throughout different international settings.

Abstract
Objectives: The aim of this systematic review is to assess the published cost-effectiveness analyses of aprepitant for patients with chemotherapy-induced nausea and vomiting (CINV). Methods: A systematic literature search was performed on PubMed, EMbase, the Cochrane Library, CNKI, WANFANG DATA, and CBM database. The date of publication is up to January 2019. Two reviewers independently reviewed titles, abstracts, and articles sequentially to select studies for data abstraction based on the inclusion and exclusion criteria. Disagreements were resolved and reviewers reached a consensus. The quality of the included studies was assessed according to the 24-item checklist of the consolidated health economic evaluation reporting standards (CHEERS). The costs reported by the included studies were converted to US dollars via purchasing power parities (PPP) in the year 2019 using the CCEMG–EPPI–Certer Cost Converter. Results: Thirteen articles were included based on the inclusion criteria for cost-effectiveness analysis and cost-utility analysis. Twelve studies were rated as good quality and one as a moderate quality based on the CHEERS checklist. Eight studies compared aprepitant plus 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA) and dexamethasone with the standard regimen (5-HT3RA and dexamethasone). It was concluded that aprepitant plus standard regimen was a cost-effective strategy for preventing CINV. Only one study that compared aprepitant plus 5-HT3RA with 5-HT3RA, concluded that the addition of aprepitant reduced the incidence of severe nausea, and it might also provide an economic benefit in the overall management. Four studies that compared aprepitant with other antiemetic drugs concluded that aprepitant is a cost-effective strategy for preventing CINV compared with metoclopramide. However, netupitan + palonosetron and olanzapine are cost-effective compared with aprepitant. Conclusion: This study is the first systematic evaluation of adding aprepitant to standard regimens for patients with CINV. Most economic evaluations of antiemetic medications are reported to be of good quality. Adding aprepitant to standard regimens is found to be a cost-effective strategy for preventing CINV.

Cost-effectiveness of a fixed combination of netupitant and palonosetron (NEPA) relative to aprepitant plus granisetron (APR + GRAN) for prophylaxis of chemotherapy-induced nausea and vomiting (CINV): a trial-based analysis. Support Care Cancer 2020; 28:857-866. [PMID: 31161436 PMCID: PMC6954135 DOI: 10.1007/s00520-019-04824-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Accepted: 04/23/2019] [Indexed: 11/25/2022]
Abstract
PURPOSE To assess, from a United States (US) perspective, the cost-effectiveness of chemotherapy-induced nausea and vomiting (CINV) prophylaxis using a single dose of netupitant and palonosetron in a fixed combination (NEPA) versus aprepitant plus granisetron (APR + GRAN), each in combination with dexamethasone, in chemotherapy-naïve patients receiving highly emetogenic chemotherapy (HEC). METHODS We analyzed patient-level outcomes over a 5-day post-HEC period from a randomized, double-blind, phase 3 clinical trial of NEPA (n = 412) versus APR + GRAN (n = 416). Costs and CINV-related utilities were assigned to each subject using published sources. Parameter uncertainty was addressed via multivariate probabilistic sensitivity analyses (PSA). RESULTS Compared to APR + GRAN, NEPA resulted in a gain of 0.09 quality-adjusted life-days (QALDs) (4.04 vs 3.95; 95% CI -0.06 to 0.25) and a significant total per-patient cost reduction of $309 ($943 vs $1252; 95% CI $4-$626), due principally to $258 in lower medical costs of CINV-related events ($409 vs $668; 95% CI -$46 to $572) and $45 in lower study drug costs ($531 vs $577). In the PSA, NEPA resulted in lower costs and higher QALD in 86.5% of cases and cost ≤ $25,000 per quality-adjusted life-year gained in 97.8% of cases. CONCLUSIONS This first-ever economic analysis using patient-level data from a phase 3 trial comparing neurokinin-1 receptor antagonist (NK1 RA) antiemetic regimens suggests that NEPA is highly cost-effective (and in fact cost-saving) versus an aprepitant-based regimen in post-HEC CINV prevention. Actual savings may be higher, as we focused only on the first chemotherapy cycle and omitted the impact of CINV-related chemotherapy discontinuation.

Abstract
BACKGROUND/AIM Although neurokinin-1 receptor antagonists are approved chemotherapy drugs in Japan, no nationwide surveys have been performed to validate chemotherapy-induced nausea and vomiting (CINV) guidelines in clinical practice. This study evaluated CINV in patients with haematological malignancies starting first-time chemotherapy. PATIENTS AND METHODS A nationwide CINV survey on patients with haematological malignancies was conducted at 118 institutions. Patients undergoing moderately emetic chemotherapy (n=17) and highly emetic chemotherapy (HEC; n=180) were compared. RESULTS Forty-one patients undergoing HEC received triple antiemetics. Female gender and young age were risk factors for early-phase nausea, while female gender remained a risk factor for late-phase nausea and vomiting. Among 125 patients receiving CHOP (doxorubicin, cyclophosphamide, vincristine, prednisone)-like regimens, complete response and complete control were increased in patients receiving triple antiemetics, compared to those with double antiemetics. CONCLUSION Guideline compliance was very low. Although not statistically significant, there was a trend for reduced CINV and improved disease control for triple versus double antiemetics, suggesting that triple antiemetics should be considered for HEC, especially in young female patients with non-Hodgkin lymphoma receiving CHOP-like regimens.

Abstract
BACKGROUND An antiemetic triplet regimen of 5-hydrotryptamine-3 receptor antagonist, dexamethasone, and aprepitant is the standard prophylaxis with highly emetogenic chemotherapy (HEC). A randomized phase III trial comparing palonosetron (PALO) versus granisetron (GRA) in the triplet antiemetic regimen (The TRIPLE study) showed the superiority of PALO over GRA for delayed-phase vomiting in patients receiving cisplatin-based HEC. However, economic efficiency evaluations including quality of life have not been done. The present study was a cost-utility analysis of PALO within the Japanese medical insurance system. METHODS The data source was the results of the TRIPLE study. A decision tree was constructed to assess the incremental cost-effectiveness ratio (ICER) using quality-adjusted life years (QALYs) and the medical service fees and the drug price for 2018 from the perspective of the payer. A one-way sensitivity analysis and a probabilistic sensitivity analysis (PSA) were performed to assess the robustness of the model. A threshold analysis was performed to determine the cost-effective price of PALO. RESULTS In the base case, the estimated incremental effect of PALO addition was 0.000645 QALYs, the estimated incremental cost was 10,455 JPY (93.21 USD), and the ICER was 16,204,591 JPY QALY (144,465 USD/QALY). In the PSA, the probability of superior cost-effectiveness was 3.64%. In the threshold analysis, the acceptable price of PALO was estimated to be 7,743 JPY (69.03 USD). CONCLUSIONS If willingness-to-pay is taken as 5,000,000 JPY/QALY (44,575 USD/QALY), the antiemetic regimen using PALO for cisplatin-containing HEC was not cost-effective at this time. The cost of drugs, with the arrival of inexpensive generic drugs, will make a major contribution to its cost-effectiveness.

Comparative Cost-utility Analysis Between Aprepitant- and Fosaprepitant-containing Regimens To Prevent Chemotherapy-induced Nausea and Vomiting in Patients Receiving Highly Emetogenic Chemotherapy in Japan. Clin Ther 2019; 41:929-942. [PMID: 31036286 DOI: 10.1016/j.clinthera.2019.03.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2018] [Revised: 01/29/2019] [Accepted: 03/17/2019] [Indexed: 11/28/2022]
Abstract
PURPOSE Clinical trials have shown that the addition of aprepitant (APR) or a phosphorylated prodrug of aprepitant, fosaprepitant (FosAPR) as prophylactic antiemetic therapy consisting of a 5-hydrotryptamine-3 receptor antagonist and dexamethasone is effective in patients receiving highly emetogenic chemotherapy. These combination therapies have been commonly used in Japan. In the present study, we performed a cost-utility analysis of APR and FosAPR in the context of the Japanese medical insurance system, and economic efficiency was compared. METHODS Data from randomized controlled trials that examined the efficacy of APR and FosAPR in the Japanese population were used. A decision tree was constructed to estimate the effectiveness of chemotherapy for 5 days from the day of the treatment and the cost associated with outpatient chemotherapy from the perspective of a payer. Health outcome was expressed in quality-adjusted life-years (QALYs), and costs were estimated based on medical fees and drug prices from 2018. An incremental cost-effectiveness ratio (ICER) was calculated for each regimen containing either APR or FosAPR. The robustness of the model was assessed using 1-way and probabilistic sensitivity analysis. FINDINGS The base-case analysis estimated that the addition of APR or FosAPR would have incremental effects of 0.00166 and 0.00143 QALY and incremental costs of 8305 and 11,348 JPY (74 and 101 USD [1 USD = 112.17 JPY]), resulting in ICERs of 4,992,172 and 7,955,560 JPY/QALY (44,505 and 70,924 USD/QALY), respectively. Sensitivity analysis revealed that the probability of a complete response for delayed chemotherapy-induced nausea and vomiting had the most influence on the ICERs. Reductions in the drug costs of APR and FosAPR also had an effect on the ICERs. According to the probabilistic sensitivity analysis, APR and FosAPR were dominant in terms of cost-effectiveness in 48.7% and 8.55% of cases, respectively. IMPLICATIONS The ICER of outpatient prophylactic antiemetic therapy in patients receiving highly emetogenic chemotherapy was calculated in the context of the Japanese medical insurance system. Assuming the willingness-to-pay of 5,000,000 JPY/QALY based on the calculated ICER, our findings suggest that although the addition of APR is cost-effective, FosAPR is not cost-effective.

Abstract
PURPOSE Neurokinin-1 receptor antagonist (NK1RA) is recommended to prevent chemotherapy-induced nausea and vomiting (CINV) in patients who receive highly or moderately emetogenic chemotherapy (HEC or MEC, respectively). We previously reported that aprepitant, an NK1RA, was needed to control CINV in 43% and 12% of patients who received HEC and MEC, respectively (Support Care Cancer 23:905-912, 2015). To elucidate the cost-effectiveness of aprepitant in these patients, a cost-utility analysis according to the necessity of aprepitant was performed. METHODS A decision-analytic model was developed according to the necessity of aprepitant and CINV responses in both acute and delayed phases of chemotherapy. Probabilities of health states and medical costs were derived from the results of the abovementioned trial. RESULT In patients who received HEC and needed aprepitant, the incremental cost-effectiveness ratio (ICER) with aprepitant, relative to the regimen with no aprepitant, was 7912 US dollars (USD) per quality-adjusted life year (QALY) gained, which was far below the commonly accepted threshold of 50,000 USD/QALY. The ICER was 27,457 USD/QALY in patients who received MEC and needed aprepitant. In contrast, in patients who received HEC or MEC but did not need aprepitant, the ICER was 175,959 or 478,844 USD/QALY, respectively. CONCLUSION Regardless of whether a patient received HEC or MEC, aprepitant use was highly cost-effective for patients who truly needed it. These results warrant further research to predict the necessity of NK1RA treatment before initiating emetogenic chemotherapies.

Economic analysis of palonosetron versus granisetron in the standard triplet regimen for preventing chemotherapy-induced nausea and vomiting in patients receiving highly emetogenic chemotherapy in Japan (TRIPLE phase III trial). J Pharm Health Care Sci 2018; 4:31. [PMID: 30555710 PMCID: PMC6287343 DOI: 10.1186/s40780-018-0128-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Accepted: 11/14/2018] [Indexed: 11/25/2022] Open
Abstract
Background We conducted an economic assessment using test data from the phase III TRIPLE study, which examined the efficacy of a 5-hydroxytryptamine 3 receptor antagonist as part of a standard triplet antiemetic regimen including aprepitant and dexamethasone in preventing chemotherapy-induced nausea and vomiting in patients receiving cisplatin-based highly emetogenic chemotherapy (HEC). Methods We retrospectively investigated all medicines prescribed for antiemetic purposes within 120 h after the initiation of cisplatin administration during hospitalization. In the TRIPLE study, patients were assigned to treatment with granisetron (GRA) 1 mg (n = 413) or palonosetron (PALO) 0.75 mg (n = 414). The evaluation measure was the cost-effectiveness ratio (CER) assessed as the cost per complete response (CR; no vomiting/retching and no rescue medication). The analysis was conducted from the public healthcare payer’s perspective. Results The CR rates were 59.1% in the GRA group and 65.7% in the PALO group (P = 0.0539), and the total frequencies of rescue medication use for these groups were 717 (153/413 patients) and 573 (123/414 patients), respectively. In both groups, drugs with antidopaminergic effects were chosen as rescue medication in 86% of patients. The costs of including GRA and PALO in the standard triplet antiemetic regimen were 15,342.8 and 27,863.8 Japanese yen (JPY), respectively. In addition, the total costs of rescue medication use were 73,883.8 (range, 71,106.4–79,017.1) JPY for the GRA group and 59,292.7 (range, 57,707.5–60,972.8) JPY for the PALO group. The CERs (JPY/CR) were 26,263.4 and 42,628.6 for the GRA and PALO groups, respectively, and the incremental cost-effectiveness ratio (ICER) between the groups was 189,171.6 (189,044.8–189,215.5) JPY/CR. Conclusions We found that PALO was more expensive than GRA in patients who received a cisplatin-based HEC regimen.

Abstract
OBJECTIVE: Despite the guideline-directed therapy, complete absence of nausea was noted only in 33% of breast cancer patients on anthracycline-cyclophosphamide regimen. Hence, we sought to compare the efficacy of aprepitant (APT) versus olanzapine (OLP) in preventing chemotherapy-induced nausea and vomiting (CINV) in breast cancer patients on doxorubicin-cyclophosphamide regimen. PATIENTS AND METHODS: A prospective, open-label, nonrandomized study was conducted at the Department of Oncology. Eighty-three patients completed the study with 43 in the APT group and 40 in OLP group. Data about nausea and vomiting were collected using Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT). The severity of nausea and vomiting was assessed by the MAT and Common Terminology Criteria for Adverse Events (CTCAE) version 4.03, respectively. RESULTS: Complete response (no emesis and no rescue medication) was achieved in 81% of the patients in APT group and 85% in the OLP group in the acute period (P = 0.661); 74% of patients in APT group and 85% in OLP group had no nausea during the same period (P = 0.233). Among the OLP patients who had nausea, 67% had moderately severe and 33% had Severe grade, and in the APT group, severity was equally distributed in mild, moderate, and severe grades. Among the patients who had vomiting, severe (CTCAE) vomiting was noticed in 81% of patients who were treated with APT compared to 50% in OLP group. CONCLUSION: OLP was found to be an equally effective alternative to APT in the antiemetic prophylaxis of CINV in breast cancer patients receiving chemotherapy with doxorubicin-cyclophosphamide regimen.

Abstract
Chemotherapy‐induced nausea and vomiting (CINV) remains a major adverse event in cancer chemotherapy. Although aprepitant is effective in preventing CINV, an increment in financial burden for uniform use of aprepitant is a concern. The aim of the present study was to define the cost‐effectiveness of aprepitant from the perspective of the Japanese National Health Insurance system. Based on the results of a randomized phase II trial comparing an aprepitant‐containing regimen versus a nonaprepitant regimen in Japanese patients who received cisplatin‐containing highly emetogenic chemotherapy, a decision analytic model was developed. The incremental cost‐effectiveness ratio (ICER) was calculated both in the outpatient care setting (OCS) and in the inpatient care setting (ICS). The use of the aprepitant‐containing regimen was associated with improved quality of life compared with the nonaprepitant regimen, with an increment in quality‐adjusted life years (QALY) of 0.0016. The incremental total medical costs associated with the use of the aprepitant regimen were lower in the OCS than in the ICS, 6192 JPY (56.92 USD) and 9820 JPY (90.27 USD), respectively. The ICER was calculated as 3 906 698 JPY (35 910 USD) per QALY gained in the OCS and 6 195 781 JPY (56 952 USD) per QALY gained in the ICS. Cost‐effectiveness of the aprepitant‐containing antiemetic therapy was limited to the OCS, considering the threshold of willingness‐to‐pay commonly accepted (5 million JPY [45 960 USD] in Japan and 50 000 USD in the USA). The efficacy of aprepitant offsets the costs for revisiting clinics or rehospitalization added with rescue medications in the OCS.

Abstract
PURPOSE Chemotherapy-induced nausea and vomiting (CINV) causes significant morbidity among colorectal cancer patients, receiving fluorouracil, oxaliplatin, and leucovorin (FOLFOX) chemotherapy even with standard antiemetic prophylaxis. The purpose of this study is to determine if the addition of aprepitant to standard antiemetic therapy improves CINV in these patients. METHODS Patients receiving FOLFOX for colorectal cancer were given antiemetic prophylaxis with aprepitant 125 mg orally on day 1 and 80 mg on days 2 and 3. Palonosetron 0.25 mg was given IV push on day 1 only. Dexamethasone 12 mg was administered orally on day 1 and 8 mg each morning on days 2 through 4. Assessments including emetic events, rescue doses, nutritional intake, and appetite were recorded in a patient diary which was returned to study personnel in the following cycle. RESULTS Of the 53 patients screened, 50 were evaluable and had a complete dataset for cycle 1. For the first cycle, 74% of patients achieved a complete response (CR), 22% achieved a major response and 4% experienced treatment failure. The percentage of patients achieving a CR remained high throughout each cycle at 83, 83, and 86% for cycles 2, 3, and 4, respectively. Appetite and nutritional status remained largely unchanged throughout treatment. Adverse events occurring in more than 10% of patients included diarrhea (13.6%), fatigue (12.6%), and neutropenia (11%). CONCLUSIONS Aprepitant added to standard antiemetic therapy appears to be an effective and safe regimen for prevention of CINV in patients receiving FOLFOX.

Abstract
OBJECTIVE To evaluate the efficiency of resources allocation and sustainability of the use of netupitant+palonosetron (NEPA) for chemotherapy-induced nausea and vomiting (CINV) prophylaxis assuming the Italian National Health Service (NHS) perspective. A published Markov model was adapted to assess the incremental cost-utility ratio of NEPA compared with aprepitant (APR) + palonosetron (PALO), fosaprepitant (fAPR) + PALO, APR + ondansetron (ONDA), fAPR + ONDA in patients receiving a highly emetogenic chemotherapy (HEC) and with APR + PALO and fAPR + PALO in patients receiving a moderately emetogenic chemotherapy (MEC). SETTING Oncology hospital department in Italy. METHODS A Markov model was used to determine the impact of NEPA on the budget of the Italian NHS on a 5-day time horizon, corresponding to the acute and delayed CINV prophylaxis phases. Direct medical costs considered were related to antiemetic drugs, adverse events management, CINV episodes management. Clinical and quality of life data referred to previously published works. The budget impact analysis considered the aforementioned therapies plus PALO alone (for HEC and MEC) on a 5-year time horizon, comparing two scenarios: one considering the use of NEPA and one not considering its use. PRIMARY AND SECONDARY OUTCOME MEASURES Incremental cost per quality adjusted life year (QALY) and differential economic impact for the Italian NHS between the two scenarios considered. RESULTS NEPA is more effective and less expensive (dominant) compared with APR + PALO (for HEC and MEC), fAPR + PALO (for HEC and MEC), APR + ONDA (for HEC), fAPR + ONDA (for HEC). The use of NEPA would lead to a 5-year cost decrease of €63.7 million (€42.7 million for HEC and €20.9 million for MEC). CONCLUSIONS NEPA allows an efficient allocation of resources for the Italian NHS and it is sustainable, leading to a cost decrease compared with a scenario which does not consider its use.

NEPA, a new fixed combination of netupitant and palonosetron, is a cost-effective intervention for the prevention of chemotherapy-induced nausea and vomiting in the UK. Drugs Context 2017; 6:212298. [PMID: 28392826 PMCID: PMC5378057 DOI: 10.7573/dic.212298] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Accepted: 12/22/2016] [Indexed: 01/26/2023] Open
Abstract
Background The objective was to evaluate the cost-effectiveness of NEPA, an oral fixed combination netupitant (NETU, 300 mg) and palonosetron (PA, 0.5 mg) compared with aprepitant and palonosetron (APPA) or palonosetron (PA) alone, to prevent chemotherapy-induced nausea and vomiting (CINV) in patients undergoing treatment with highly or moderately emetogenic chemotherapy (HEC or MEC) in the UK. Scope A systematic literature review and meta-analysis were undertaken to compare NEPA with currently recommended anti-emetics. Relative effectiveness was estimated over the acute (day 1) and overall treatment (days 1–5) phases, taking complete response (CR, no emesis and no rescue medication) and complete protection (CP, CR and no more than mild nausea [VAS scale <25 mm]) as primary efficacy outcomes. A three-health-state Markov cohort model, including CP, CR and incomplete response (no CR) for HEC and MEC, was constructed. A five-day time horizon and UK NHS perspective were adopted. Transition probabilities were obtained by combining the response rates of CR and CP from NEPA trials and odds ratios from the meta-analysis. Utilities of 0.90, 0.70 and 0.24 were defined for CP, CR and incomplete response, respectively. Costs included medications and management of CINV-related events and were obtained from the British National Formulary and NHS Reference Costs. The expected budgetary impact of NEPA was also evaluated. Findings In HEC patients, the NEPA strategy was more effective than APPA (quality-adjusted life days [QALDs] of 4.263 versus 4.053; incremental emesis-free and CINV-free days of +0.354 and +0.237, respectively) and was less costly (£80 versus £124), resulting in NEPA being the dominant strategy. In MEC patients, NEPA was cost effective, cumulating in an estimated 0.182 extra QALDs at an incremental cost of £6.65 compared with PA. Conclusion Despite study limitations (study setting, time horizon, utility measure), the results suggest NEPA is cost effective for preventing CINV associated with HEC and MEC in the UK.

Abstract
AIM We aim to evaluate the cost effectiveness of aprepitant-containing regimens for the prevention of chemotherapy-induced nausea and vomiting (CINV) among patients receiving high emetogenic chemotherapy (HEC) in Hong Kong. METHODS Both cost-effectiveness and cost-utility analyses were conducted utilizing a decision-analytic model to measure the economic costs and clinical outcomes associated with the aprepitant-containing regimen versus a standard regimen in the prevention of CINV. Analyses were conducted on the basis of four published double-blind randomized clinical trials involving different usages of serotonin receptor antagonists. RESULTS The use of aprepitant-containing regimens is associated with an improvement in quality-adjusted life years (QALYs) compared with non-aprepitant regimens. For cisplatin-based chemotherapy, the incremental cost per QALY gained is HKD 239,644 (1 USD approximates HKD 7.8) when ondansetron is administered on day 1 only. The incremental cost per QALY is HKD 440,950 when ondansetron is used on day 1 to 4. For anthracycline and cyclophosphamide chemotherapy, the aprepitant-containing regimen is associated with incremental cost of HKD 195,442 per QALY gained. Similar results were obtained when other 5HT3 receptor antagonists are used. The use of aprepitant was associated with higher cost of drug but lower costs of emesis-related management. With the cost-effectiveness threshold set at the World Health Organization endorsed criteria of three times gross domestic product (GDP) per capita (three times GDP per capita in Hong Kong in 2011 is HKD 798,078), the current analyses showed that the aprepitant-containing regimen was cost-effective. CONCLUSIONS In patients undergoing HEC, the use of aprepitant as the anti-emetic is cost-effective in Hong Kong.

Abstract
PURPOSE Neurokinin-1 (NK-1) receptor antagonist is recommended for chemotherapy-induced nausea and vomiting (CINV) in highly emetogenic chemotherapy (HEC) and has recently been introduced to oncology practice in Japan. However, whether all patients undergoing HEC truly need NK-1 receptor antagonist remains unknown, and increasing medical costs due to uniform use of NK-1 receptor antagonist are a concern. This study was conducted to examine the prevalence of patients who needed aprepitant at the time of its introduction in Japan, and therapeutic and preventive effects of aprepitant on HEC or moderately emetogenic chemotherapy (MEC). PATIENTS AND METHODS Eligible patients with thoracic malignancies who were to undergo HEC or MEC received 5-hydroxytryptamine receptor antagonists and dexamethasone to prevent CINV. Aprepitant was administered to treat CINV occurring in the first course, or to prevent CINV in the second course. Frequency of vomiting, degree of nausea, and quality of life with respect to CINV were assessed. RESULTS In total, 96 patients were enrolled. Aprepitant was not administered in 57 and 88 % of patients who received HEC and MEC, respectively. In patients treated with aprepitant (n = 18), therapeutic use of aprepitant after occurrence of CINV (n = 9) decreased average scores in numerical rating scale for nausea from 7.44 to 5.44 (p = 0.10), and average frequency of vomiting per day from 2.11 to 0.11 (p = 0.03). Prophylactic use of aprepitant in the second course (n = 18) increased the proportion of patients with no significant nausea from 6 % (first course) to 50 % (second course; p = 0.007), and those with no vomiting from 33 to 89 % (p = 0.002). Aprepitant use also significantly improved quality of life with respect to CINV in the second course. CONCLUSION More than half of patients receiving HEC and 88 % of patients receiving MEC did not use aprepitant. Aprepitant showed significant therapeutic and preventive effects on CINV in patients who truly needed it.

Abstract
Chemotherapy-induced nausea and vomiting (CINV) is a troubling side effect of cancer treatment and is often poorly controlled. As a consequence, CINV is associated with substantially increased costs of care and significant interference with patients' lives. Inadequate control over CINV results from factors that include failure to provide guideline-adherent prophylactic medication and limitations in available therapies. Newer serotonin receptor antagonists, such as palonosetron, and addition of neurokinin-1 (NK-1) receptor antagonists to treatment have significantly decreased both acute and delayed CINV. A fixed-dose combination of palonosetron and a new NK-1 receptor, netupitant, is significantly superior to palonosetron alone and has small, but consistent, numerical advantages over aprepitant plus palonosetron for prevention of CINV. The combination of a serotonin receptor antagonist plus an NK-1 receptor antagonist has been shown to be cost-effective for prevention of CINV and the availability of a fixed-dose combination of netupitant and palonosetron may enhance this benefit.

Abstract
BACKGROUND In a prospective cohort study of antiemetic therapy conducted in Malaysia, a total of 94 patients received low emetogenic chemotherapy (LEC) with or without granisetron injections as the primary prophylaxis for chemotherapy-induced nausea and vomiting (CINV). This study is a retrospective cost analysis of two antiemetic regimens from the payer perspective. MATERIALS AND METHODS This cost evaluation refers to 2011, the year in which the observation was conducted. Direct costs incurred by hospitals including the drug acquisition, materials and time spent for clinical activities from prescribing to dispensing of home medications were evaluated (MYR 1=$0.32 USD). As reported to be significantly different between two regimens (96.1% vs 81.0%; p=0.017), the complete response rate of acute emesis which was defined as a patient successfully treated without any emesis episode within 24 hours after LEC was used as the main indicator for effectiveness. RESULTS Antiemetic drug acquisition cost per patient was 40.7 times higher for the granisetron-based regimen than for the standard regimen (MYR 64.3 vs 1.58). When both the costs for materials and clinical activities were included, the total cost per patient was 8.68 times higher for the granisetron-based regimen (MYR 73.5 vs 8.47). Considering the complete response rates, the mean cost per successfully treated patient in granisetron group was 7.31 times higher (MYR 76.5 vs 10.5). The incremental cost-effectiveness ratio (ICER) with granisetron-based regimen, relative to the standard regimen, was MYR 430.7. It was found to be most sensitive to the change of antiemetic effects of granisetron-based regimen. CONCLUSIONS While providing a better efficacy in acute emesis control, the low incidence of acute emesis and high ICER makes use of granisetron as primary prophylaxis in LEC controversial.

Abstract
BACKGROUND Aprepitant (Emend, Merck Sharp & Dohme Ltd, Haarlem, the Netherlands), a neurokinin-1 receptor antagonist, prevents vomiting in a range of conditions. No data are available on its use in children with cyclical vomiting syndrome (CVS). AIM We investigated the efficacy of aprepitant as prophylactic treatment or acute intervention in CVS children refractory to conventional therapies. METHODS Forty-one children (median age: 8 years) fulfilling NASPGHAN criteria treated acutely (RegA) or prophylactically (RegP) with aprepitant were retrospectively reviewed. Primary outcome was the clinical response (decrease in frequency and intensity of CVS episodes). Secondary outcomes were: number of CVS episodes/year, number of hospital admissions/year, CVS episode duration, number of vomits/h, symptom-free interval length (days), and school attendance percentage. The follow-up period was 18-60 months. RESULTS Sixteen children received RegP and 25 RegA. One child on RegP stopped treatment due to severe migraine. At 12-months on intention-to-treat analysis, 13 children on RegP (81%) achieved either complete (3/16, 19%) or partial (10/16, 62%) clinical response. On RegA, 19 children (76%) had either complete (3/25, 12%) or partial (16/25, 64%) response (P = 0.8 vs. RegP). In both RegP and RegA, there was a significant decrease in CVS episodes/year, hospital admission number/year, CVS episode length, number of vomits/h, as well as an increase in symptom-free interval duration and school attendance percentage. Side effects were reported only in RegP (5/16, 31%) including hiccough (3/16, 19%), asthenia/fatigue (2/16, 12.5%), increased appetite (2/16, 12.5%), mild headache (1/16, 6%) and severe migraine (1/16, 6%). CONCLUSION Aprepitant appears effective for both acute and prophylactic management of paediatric cyclical vomiting syndrome refractory to conventional therapies.

Abstract
INTRODUCTION Triptans have been safely and effectively used in the management of migraine for more than fifteen years, and it seems reasonable to wonder what would be the economic impact of moving a specific triptan to OTC availability. The objective of this study was then to examine the economic impact of payer policies of a triptan Rx-to-OTC switch in six EU countries (France, UK, Spain, Italy, Germany and Poland). METHODS A decision model was used to model the budgetary impact of a triptan Rx-to-OTC switch from the third-party payer (TPP) and the societal perspectives, using a one-year timeframe. RESULTS From the TPP perspective, it is estimated that the current overall direct spending on the management of migraine attacks across the 6 EU Member States is €582 million annually, and that the savings would reach €75 million (13% of the overall direct economic burden of migraine). From the societal perspective, €86 million annually would be added. CONCLUSIONS Given evidence of effectiveness and safety, and given the potential savings, a triptan Rx-to-OTC switch is a reasonable public policy decision.

Abstract
BACKGROUND Antineoplastic drugs for cancer are often associated with adverse events, which influence patients' physical health, quality of life and survival. However, the modelling of adverse events in cost-effectiveness analyses of antineoplastic drugs has not been examined. AIMS This article reviews published economic evaluations that include a calculated cost for adverse events of antineoplastic drugs. The aim is to identify how existing models manage four issues specific to antineoplastic drug adverse events: the selection of adverse events for inclusion in models, the influence of dose modifications on drug quantity and survival outcomes, the influence of adverse events on quality of life and the consideration of multiple simultaneous or recurring adverse events. METHODS A systematic literature search was conducted using MESH headings and key words in multiple electronic databases, covering the years 1999-2009. Inclusion criteria for eligibility were papers covering a population of adults with solid tumour cancers, the inclusion of at least one adverse event and the resource use and/or costs of adverse event treatment. RESULTS From 4,985 citations, 26 eligible articles were identified. Studies were generally of moderate quality and addressed a range of cancers and treatment types. While the four issues specific to antineoplastic drug adverse events were addressed by some studies, no study addressed all of the issues in the same model. CONCLUSION This review indicates that current modelling assumptions may restrict our understanding of the true impact of adverse events on cost effectiveness of antineoplastic drugs. This understanding could be improved through consideration of the selection of adverse events, dose modifications, multiple events and quality of life in cost-effectiveness studies.

Abstract
Side effects or toxicities are frequent, undesirable companions of almost all forms of non-surgical cancer therapy. It is unusual for patients to complete treatment with radiation or chemotherapy without experiencing at least one form of therapy-associated tissue injury or systemic side effect. Often, toxicities do not occur as solitary events; rather, they result in clusters of symptoms that share a common biological aetiology. Like any disease, cancer treatment-related toxicities (CTRTs) vary in their severity. But, in contrast to most diseases in which incidence is described as being present or absent, the current approach to CTRT typically limits reporting to severe cases only. Not only does this dilute the frequency with which CTRTs occur, but it also undermines our ability to determine the full burden of their impact and to accurately assess the cost effectiveness of potential toxicity interventions. In this article, we report the results of a directed literature review for the years 2000-2012, in which we studied and compared three tissue-based toxicities (nausea and vomiting, diarrhoea, and oral mucositis) and one systemic toxicity (fatigue). Our results confirm the heavy burden of resource use and cost associated with CTRTs. The inclusion of fatigue in our analysis provided an opportunity to compare and contrast a toxicity in which there are both acute and chronic consequences. Our findings also demonstrate a number of challenges to, and opportunities for, future study. Among the most obvious are the lack of provider consistency in diagnosis and grading, especially when there is no global agreement on severity scales. Compounding this inconsistency is the disconnect between healthcare providers and patients that exists when describing toxicity severity and impact. In many cases, cancer can be thought of as a chronic disease that requires prolonged but episodic treatment once the acute disease is eradicated. This change reflects increasing treatment successes, but it also implies that the burden of CTRTs will be expanded and prolonged. Creation of hierarchical attribution of costs in the presence of simultaneous CTRTs, accurate coding, and consistent tracking tools for toxicities will be imperative for effective appraisal of the costs associated with cancer treatment regimen toxicities.

Abstract
Control of chemotherapy-induced nausea and vomiting (CINV) is a crucial factor in ensuring that patients undergoing cancer chemotherapy can get the full benefit of therapy. Current antiemetic guidelines recommend that the neurokinin-1 receptor (NK-1R) antagonist aprepitant should be used as part of a combination regimen with dexamethasone and a serotonin receptor antagonist for the prevention of CINV in patients receiving highly emetogenic chemotherapy (HEC). Fosaprepitant is a water-soluble N-phosphoryl derivative of aprepitant that, when infused, is rapidly metabolized back to an active aprepitant. The existing literature in PubMed about fosaprepitant was screened and selected in order to address the emerging data from two randomized clinical trials evaluating the efficacy and safety of a single-dose fosaprepitant regimen. These phase III trials demonstrated that fosaprepitant given as a single intravenous dose of 150 mg was either noninferior to the conventional 3-day aprepitant or significantly superior to placebo for the prevention of acute and delayed CINV in patients receiving high-dose cisplatin. In both trials, fosaprepitant was well tolerated although more frequent infusion-site adverse events were observed with fosaprepitant. The new dosage regimen of fosaprepitant, therefore, would be an option for CINV control in patients receiving cisplatin-based chemotherapy. The clinical efficacy is consistent with the findings from a time-on-target, positron-emission tomography study evaluating the NK-1R occupancy in the central nervous system (CNS) over 5 days after a single-dose infusion of 150 mg fosaprepitant in healthy participants. The single-dose regimen is capable of blocking more than 90% of the NK-1Rs in the CNS for at least 48 hours after infusion, which is sufficient to control delayed CINV for 2 to 5 days after HEC. The new dosage regimen of fosaprepitant can provide a simplified treatment option that maintains high protection while ensuring adherence to scheduled antiemetic medication throughout most of the 5-day period encompassing the major risk for CINV.

Abstract
BACKGROUND Aprepitant (a neurokinin 1 receptor antagonist), in combination with a serotonin receptor antagonist (5-HT3 RA) and dexamethasone, has demonstrated superior efficacy on end points related to chemotherapy-induced nausea and vomiting (CINV) compared with standard care (combination 5-HT3 RA and dexamethasone). OBJECTIVE To determine the cost-effectiveness of an aprepitant-containing regimen compared with current clinical practice for the prevention of CINV in patients receiving highly emetogenic chemotherapy (HEC) in Singapore. METHODS A decision-analytic model was constructed to assess the costs and outcomes associated with an aprepitant-containing regimen compared with standard care in the prevention of CINV following HEC. Three scenarios were modeled on the basis of results of four double-blind randomized clinical trials of aprepitant. CINV event probabilities were calculated on the basis of the occurrence of nausea and vomiting and the need for rescue medication in the 5 days following a single cycle of HEC. The analysis was conducted from the Singapore health care system perspective. RESULTS Aprepitant reduced emesis and nausea, resulting in small but clinically important improvements when measured in quality-adjusted life-years. The aprepitant-containing regimen was associated with higher acquisition costs but lower costs relating to patient management, hospitalization, and use of rescue medication. Across the scenarios, the incremental cost per emetic event avoided ranged from cost saving to Singapore $63 (US $51). The incremental cost-effectiveness ratio ranged from cost saving to Singapore $49,800 per quality-adjusted life-year gained (US $40,600). The analysis was relatively insensitive to changes in the inputs. CONCLUSIONS Aprepitant is a clinically important and cost-effective therapy for the prevention of CINV in patients treated with HEC in Singapore.

Abstract
UNLABELLED The cost-effectiveness of bazedoxifene was compared to placebo in France, Germany, Italy, Spain, Sweden and the UK from a healthcare perspective using FRAX® for both fracture risks and for treatment efficacy. Cost/QALY differences were explained to a large extent by differences in fracture risk. INTRODUCTION In cost-effectiveness modelling of osteoporosis treatments, the fracture risk has traditionally been calculated with risk adjustments based on age, bone mineral density and prior fracture. However, knowledge of additional clinical risk factors contributes to fracture risk assessment as demonstrated by the FRAX® tool. Bazedoxifene, a new selective estrogen receptor modulator for the treatment and prevention of osteoporosis, has been shown in a phase III clinical trial to reduce the risk of osteoporotic fractures in women. In an analysis using FRAX®, the efficacy of bazedoxifene was greater in patients with higher fracture risk. METHODS The aim of this study was to evaluate the cost-effectiveness of bazedoxifene compared to placebo in France, Germany, Italy, Spain, Sweden and the UK from a healthcare perspective using FRAX®. A Markov cohort model was adapted to incorporate the FRAX® risk factors. FRAX® produces relative risks for hip fractures and major osteoporotic fractures. Patients were given a 5-year intervention, reducing the risk of fractures in a risk-dependent manner. The effect of treatment on fractures was assumed to decline linearly over 5 years after the intervention. RESULTS There are large cost/quality-adjusted life year variations between countries in the European setting studied. The base case values ranged from cost saving (Sweden) to EUR 105,450 (Spain) in 70-year-old women with a T-score of -2.5 SD and a prior fracture. CONCLUSION Bazedoxifene can be a cost-effective treatment for postmenopausal osteoporosis. The variability between countries was explained to a large extent by differences in fracture risk, and the estimated cost-effectiveness was highly dependent on the population's FRAX®-estimated probability of major osteoporotic fracture.

Abstract
INTRODUCTION The selective neurokinin-1 receptor antagonist aprepitant is effective in the treatment of acute and delayed chemotherapy-induced nausea and vomiting (CINV) associated with both moderately and highly emetogenic chemotherapy. Fosaprepitant has been developed as an intravenous prodrug of aprepitant. AIMS To update the evidence underlying the use of fosaprepitant to prevent CINV. EVIDENCE REVIEW Aprepitant in combination with a serotonin antagonist and a corticosteroid controls acute and delayed symptoms of CINV in patients receiving moderately to highly emetogenic chemotherapy. Bioequivalence of fosaprepitant with aprepitant has recently been demonstrated, which has led to its inclusion in clinical guidelines for treatment of acute CINV with highly, and some regimens of moderately, emetogenic chemotherapy. Early studies of the clinical efficacy of fosaprepitant have shown improvement over treatment with ondansetron. Both aprepitant and fosaprepitant are well tolerated with most adverse events observed of mild or moderate intensity. Conflicting economic evidence has shown that whilst aprepitant provides an increased quality of life in patients treated for CINV, there are differing views over its absolute cost in relation to standard therapy. The incremental cost-effectiveness ratio of aprepitant, however, appears to lie within acceptable bounds. PLACE IN THERAPY Fosaprepitant and aprepitant are recommended in guidelines for preventing CINV due to moderately and highly emetogenic chemotherapy. Fosaprepitant is bioequivalent to aprepitant, and could offer potential benefits for patients who may be unable to tolerate oral administration of antiemetics during an episode of nausea or vomiting.

Abstract
Aprepitant (Emend) is a neurokinin-1 (NK(1)) receptor antagonist that is able to alleviate the emetic effects of substance P. When combined with a standard regimen of a corticosteroid (dexamethasone) and a serotonin 5-HT(3) receptor antagonist (ondansetron), oral aprepitant (125 mg on day 1 then 80 mg once daily on days 2 and 3) was effective in the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) associated with single or multiple cycles of highly emetogenic chemotherapy (HEC). This aprepitant regimen was also effective in the prevention of CINV in patients treated with single or multiple cycles of moderately emetogenic chemotherapy (MEC). A single oral dose of aprepitant 40 mg administered prior to patients undergoing abdominal surgery was also effective in the prevention of postoperative nausea and vomiting (PONV). Aprepitant was generally well tolerated. Aprepitant is a recommended option for the treatment of PONV, and when combined with a corticosteroid and 5-HT(3) receptor antagonist is a recommended regimen for the treatment of CINV.

Abstract
Objective. To review the scientific evidence related to serotonin and substance P and the clinical impact targeting these two neurotransmitters have had managing chemotherapy-induced nausea and vomiting (CINV). Data Source. A PubMed search (January 1968 to December 2008), restricted to English-language publications, was conducted using the key words antiemetics, cancer chemotherapy, cisplatin, serotonin, substance P, NK1, and 5-HT3. Abstracts emanating from the meetings of the American Society of Clinical Oncology and Multinational Association of Supportive Care in Cancer during the period May 2000 to June 2008 were also reviewed. Data Synthesis. Two important outcomes emanated from well-conducted antiemetic clinical trials (Table 1): first, evidence that serotonin and substance P are major mediators of acute and delayed symptoms and second, improved, though not complete, control of CINV. Conclusion. Serotonin-type 3 and neurokinin-1 receptor antagonists are the most effective agents currently available. In most cases, these agents are used in conjunction with glucocorticoids. The use of these three types of agents is incorporated into current clinical practice guidelines. Further understanding of the biological and biochemical basis of nausea and vomiting may enhance management of this potentially debilitating adverse effect.
