The purpose of this study was to compare outcomes in patients who received aprepitant, azasetron, and dexamethasone versus patients who received a 5-HT3 receptor antagonist and dexamethasone.
Thirty-seven women received double combination therapy on cycle 1 and then triple combination therapy on cycle 2. Forty-one women received triple combination therapy on cycles 1 and 2. Eighty-five women only received double combination therapy. Double combination therapy consisted of azasetron 10 mg IV and dexamethasone 20 mg IV prior to chemotherapy on day 1. Triple combination therapy consisted of azasetron 10 mg IV, dexamethasone 8 mg IV and aprepitant 125 mg PO prior to chemotherapy on day 1 and then aprepitant 80 mg PO on days 2 and 3.
PHASE OF CARE: Active anti-tumor treatment
Prospective, non-randomized trial
Nausea, vomiting, and appetite loss were self-reported and measured on a scale of 0 (not present) to 2 (strongly present). Dietary intake was self-reported and measured on a scale of 0-10 for staple foods and 0-10 for side dishes (score of 20 = perfect score). It is unclear how the investigators collected this data, but it was collected for day 1 and day 5.
For the patients who received double combination therapy on cycle 1 and then triple combination therapy on cycle 2, there was a significant improvement in day 5 (delayed) nausea (p < 0.001), appetite loss (p < 0.0001), and dietary intake (p = 0.04) on cycle 2. There was not a significant difference in vomiting.
When comparing all cycles with double combination therapy to all cycles with triple combination therapy, patients who received double combination therapy for that cycle reported higher nausea (p = 0.002), appetite loss (p = 0.002), and vomiting (p = 0.02) on day 1. There were no significant differences between the two groups on day 5.
This study suggests that triple combination therapy (aprepitant plus dexamethasone plus azasetron) may result in less delayed nausea and less acute nausea, appetite loss, and vomiting, when compared to double combination therapy (dexamethasone plus azasetron). However, there are several limitations to this study.
Aprepitant, when added to dexamethasone and azasetron, for patients with gynecological cancers receiving carboplatin and paclitaxel may decrease acute nausea, appetite loss, and vomiting as well as delayed nausea.

The purpose of this study was to evaluate the efficacy of triplet therapy aprepitant, palonosetron, and dexamethasone in patients receiving carboplatin and paclitaxel (CP) for gynecologic malignancy.
Seventy patients with gynecologic cancer receiving CP were enrolled into a prospective single-arm study with APR (125 mg on day 1, 80 mg on days 2–3), PALO (0.75 mg), and DEX (20 mg) before initiating chemotherapy. The primary endpoint was delayed complete response (CR) rate (i.e., no vomiting and no rescue) at 24–120 hours after chemotherapy administration.
Single-arm phase II
Adding APR to PALO and DEX combination therapy may be promising for patients with gynecologic cancer receiving CP. A phase III study comparing APR, PALO, and DEX to PALO and DEX should be conducted in order to determine if APR in addition to PALO and DEX is efficacious for female patients receiving CP.
Encourage more studies to better determine the efficiency of APR in addition to PALO and DEX in this patient population.

STUDY PURPOSE: The primary aim of this systematic review was to compare the efficacy and safety of olanzapine with standard antiemetics.
TYPE OF STUDY: Systematic review/meta-analysis
DATABASES USED: MEDLINE, EMBASE, SCOPUS, Cochran Central Register of Controlled Trials
YEARS INCLUDED: Inception to July 15, 2016
INCLUSION CRITERIA: The studies of interest were those that reported either olanzapine as add-on treatment (dexamethasone plus 5-HT3 antagonist, with or without NK1 antagonist) or olanzapine monotherapy compared to standard treatment.
EXCLUSION CRITERIA: Duplicate data and non-English language studies.
TOTAL REFERENCES RETRIEVED: 573
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Two independent reviewers
FINAL NUMBER STUDIES INCLUDED: 16 studies however, only 9 were pooled for statistical analysis because 1 was an observational study, and 6 clinical trials did not have a comparison group.
TOTAL PATIENTS INCLUDED IN REVIEW 1,308 (in the 9 studies included in analysis)
SAMPLE RANGE ACROSS STUDIES: 17-380
KEY SAMPLE CHARACTERISTICS: Multiple tumor types, focused on patients receiving olanzapine.
PHASE OF CARE: Active anti-tumor treatment
The results of the combined studies included in the meta-analysis showed that CR (defined as no emesis and no rescue drugs) was achieved more frequently for delayed CINV (RR = 1.77, 95% CI [1.07, 1.49]) and overall CINV (RR = 1.32; 95% CI [1.08, 1.62]). Olanzapine was not superior to traditional antiemetic therapy for acute CINV. The most frequently occurring adverse events were drowsiness and constipation.
Nurses caring for patients with delayed CINV can consider the use of olanzapine, but also must recognize the common occurring drowsiness and constipation with the use of the medication.

Evaluate the safety and efficacy of olanzapine for prevention and rescue of CINV
Medical records of adult patients who received one or more doses of olanzapine for prophylaxis of CINV or treatment of breakthrough CINV were reviewed. Routinely patients are phoned by a pharmacist or research assistant 72 hours after each chemotherapy cycle and an assessment of CINV is documented in the electronic record. Patients were on various chemotherapy and antiemetic regimens.
Retrospective descriptive
Olanzapine was used for breakthrough in 154 patients over 193 treatment cycles. 88.1% of patients reported that it improved nausea, and 21.8% reported it improved vomiting. Twenty patients had been given olanzapine for prophylaxis. Among these 100% reported it improved nausea, and 35% said it improved vomiting. Analysis showed that olanzapine effects were not related to cycle, emetogenicity of the chemotherapy, or antiemetic regimen used. Side effects observed were sedation with continuation of olanzapine (29.5%).
Olanzapine was shown to have been effective as a rescue medication for CINV and may be effective for CINV prophylaxis.
Olanzapine can be effective as a rescue medication for CINV and as part of a CINV prophylaxis regimen.

Aprepitant versus metoclopramide, both combined with dexamethasone, for the prevention of cisplatin-induced delayed emesis: A randomized, double-blind study. Annals of Oncology, 26, 1248–1253.
The purpose of the study was to compare the combination of aprepitant and decadron versus metoclopramide and decadron for delayed emesis in patients receiving the same combination of aprepiant, palonosetron, and dexamethasone for the prophylaxis of cisplatin-induced acute emesis.
All patients received on day 1 a combination of 0.25 mg of palonosetron administered IV 30 minutes before the beginning of chemotherapy followed by 12 mg of decadron. Aprepitant was orally administered one hour before chemotherapy. Patients were randomized to receive delayed antiemetics with decadron 8 mg once daily day 2 to 4 plus aprepitant 80 mg daily on day 2 and 3, or decadron 8 mg twice daily on days 2 to 4 plus metoclopramide 20 mg four times a day on days 2 to 4. Patients recorded a diary card days 1 to 6 with reports of nausea, vomiting, adverse events and any rescue treatments using FLIE, and nausea intensity on a visual analog scale.
PHASE OF CARE: Active anti-tumor treatment
Multicenter, double-blind, parallel, randomized 1:1 study aimed to evaluate the efficacy of aprepitant versus metoclopramide
Fisher’s exact test was used to compare the two groups with respect to the endpoints expressed by a binary variable, as well as to evaluate the differential safety. FLIE was used for patient diary and symptom reporting, as well as a visual analog scale for nausea.
During days 2 to 5, complete response was similar in both antiemetic prophylaxes (82.5% with M + D, and 80.3% with A + D).
The effectiveness and safety of the two combinations in the treatment of cisplatin induced CINV in the delayed phase are similar. However, they have very different cost profiles. These are important considerations for treatment-related decisions.
Both aprepitant + decadron and metoclopramide + decadron are effective for delayed emesis for patients receiving cisplatin. Because of the substantial cost difference, consideration should be given to metoclopramide + decadron for delayed nausea.

To investigate the incidence of CINV among chemotherapy naïve patients with breast cancer receiving docetaxel-cyclophosphamide chemotherapy regimen (MEC). To investigate the prophylactic efficacy of aprepitant on CINV for the patients who experienced CINV in their first chemotherapy cycle
Phase 1: involved 212 breast cancer naïve patients receiving TC and detected the incidence of CINV. Antiemetic therapy on the first cycle consisted of dexamethasone 8 mg (x 3) for day 1 and then dexamethasone 8 mg (x 2) on days 2 and 3 plus 5-hydroxytryptamine (5-HT3) antagonists (gransetron 1 mg [x 2], or tropisetron 5 mg [x 1]) on day 1. Patient also received 8 mg dexamethasone on day 0.
Phase 2: for the patient who experienced vomiting and requested rescue antiemetic in the first 120 hours were involved during their second chemotherapy cycle. Patients received same antiemetic regimen prescribed in cycle 1 in addition to aprepitatnt 125 mg orally (x 1) on day 1, and aprepitant 80 mg and dexamethasone 4 mg (x 2) in days 2 and 3 Patients’ diaries and Functional Living Index Emesis (FLIE) questionnaires were collected in cycles 1 and 2.
PHASE OF CARE: Active anti-tumor treatment
Open-label, non-comparative, observational clinical trial
FLIE questionnaire on day 1 before chemotherapy and day 6. Patient diary for nausea and vomiting episodes and severity (VAS) and need of rescue antiemetics day 1-6.
On cycle 1, 87% achieved a complete response (no vomiting and no rescue antiemetic). On cycle 2, 23 patients reached a CR (52.2%). The absence of CR significant affected the patients QOL on cycle 1 (p = 0.0124) and 2 (p = 0.0059). No AEs related to aprepitant were observed in cycle 2.
Antiemetic guidelines of dexamethasone for 3 d plus 5-hydroxytryptamine (5-HT3) antagonists on day 1 is associated with low incidence of CINV for patient receiving MEC. Aprepitant is effective as a secondary treatment line for patients who do not response to the first-line antiemetic.
Even with the use of standard antiemetics (steroid, %HT3 RAs) with patient receiving MEC, some patients still experience CINV. Failing to be free of nausea and vomiting negatively affect patients’ quality of life and therefore required additional therapy (aprepitant).

Efficacy and safety of aprepitant for the prevention of chemotherapy-induced nausea and vomiting during the first cycle of moderately emetogenic chemotherapy in Korean patients with a broad range of tumor types. Supportive Care in Cancer, 25, 801–809.
The purpose was to evaluate the efficacy of a three-day aprepitant regimen to manage CINV during cycle one of moderately emetogenic chemotherapy.
Three-day regimen of aprepitant plus ondansetron and dexamethasone compared to three-day regimen of placebo plus ondansetron and dexamethasone.
PHASE OF CARE: Active anti-tumor treatment
Randomized, controlled trial, double-blind.
Measures of nausea and vomiting were not specifically described but aspects measured were vomiting during the overall phase (0-120 hours), use of rescue therapy during the overall phase, time to first vomiting event during the overall phase, vomiting during the acute (0–24 hours following initiation of chemotherapy) and delayed (25–120 hours following initiation of chemotherapy) phases.
Participants who received the three-day aprepitant regimen did not have statistically significant fewer episode of vomiting or use of rescue medications in the overall phase (0-120 hours after chemotherapy) as compared with those who received the placebo regimen.
The addition of aprepitant to a standard antiemetic regimen for moderately emetogenic chemotherapy did not result in significant improvement in CINV.
Measurement/methods not well described
For patients receiving moderately emetogenic chemotherapy, adding aprepitant to antiemetic therapy may not provide additional prevention of CINV.

TOTAL REFERENCES RETRIEVED: 626
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Initial evaluation done by one member of team, but two others then reviewed the results, and agreement was reached using consensus.
FINAL NUMBER STUDIES INCLUDED: 16 per literature, 15 evaluated in table.
TOTAL PATIENTS INCLUDED IN REVIEW: 3,848
SAMPLE RANGE ACROSS STUDIES: 23-707
KEY SAMPLE CHARACTERISTICS: Studies evaluating the efficacy of NK-1 in chemotherapy with moderately emetogenic chemotherapy, multiple types of cancer, lung, gynecologic, colorectal, and head and neck cancers
PHASE OF CARE: Active anti-tumor treatment
APPLICATIONS: Elder care, palliative care
Overall, a total of 626 published articles or abstracts were pulled for this systemic review. Based on the inclusion and exclusion criteria, the final review included 13 trials and three abstracts. Only two trials evaluated use of NK-1 in pure MEC regimens. The authors categorized trials as pure MEC (excluding regimens with carboplatin or oxaliplatin), regimens containing carboplatin, and regimens containing oxaliplatin. In the pure MEC group, the addition of an NK-1-RA significantly improved CINV complete response (p = 0.02). In the carboplatin group, the addition of an NK-1-RA significantly improved CINV complete response (p < 0.001). In the oxaliplatin group, the addition of an NK-1-RA did not significantly improved CINV complete response (p = 0.17).
The authors discuss that the addition of NK-1 does improve CINV in carboplatin regimens with moderate emetogenicity, but the benefit is not clear for other moderately emetogenic chemotherapy regimens. This use of NK-1 in moderately emetogenic chemotherapy is not reported in guidelines, but there is still a need to answer the question of benefit in this patient population. With carboplatin, there was evidence of usefulness in patients receiving carboplatin with doses at AUC 4 and above. In mixed regimens, it is difficult as emetogenicity ranges from 30%-90%. Only two trials were evaluated in oxaliplatin containing regimens.
Consideration of adding NK-1 in carboplatin containing regimens is supported by results. Ongoing research is needed to further define patients who would benefit from NK-1 medications.

SAMPLE RANGE ACROSS STUDIES: 36–1,449
KEY SAMPLE CHARACTERISTICS: People with cancer, receiving chemotherapy for cancer
PHASE OF CARE: Active anti-tumor treatment
Compiling the results from all eligible studies reviewed, the authors found that adding a NK1RA to a standard antiemetic regimen provided better emesis control than a standard antiemetic regimen alone in patients receiving cisplatin-based highly emetogenic chemotherapy and anthracycline/cyclophosphamide (AC)-based highly emetogenic chemotherapy (all p < 0.00001). In patients receiving moderately emetogenic chemotherapy, there were no statistically significant differences in emesis between NK1RA plus standard antiemetic regimen and standard antiemetic regimen alone. In patients receiving high-dose chemotherapy before stem cell transplantation and cisplatin-based multiple-day chemotherapy (MDC) regimens, adding a NK1RA to a standard antiemetic regimen provided better emesis control (all p < 0.05).
Adding an NK1RA to standard antiemetic regimens can reduce CINV in patients receiving highly emetogenic chemotherapy. Adding an NK1RA to standard antiemetic regimens with moderately emetogenic therapy did not demonstrate an added benefit to preventing CINV.
Adding an NK1RA to standard antiemetic regimens in people receiving a chemotherapy regimen classified as highly emetogenic can reduce CINV.

Phase II open label pilot trial of aprepitant and palonosetron for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving moderately emetogenic FOLFOX chemotherapy for the treatment of colorectal cancer. Supportive Care in Cancer, 26, 1273–1279.
To determine the efficacy of aprepitant added to standard antiemetic therapy for the control of CINV in patients with colorectal cancer receiving FOLFOX (fluorouracil, oxaliplatin, and leucovorin) chemotherapy.
Patients with colorectal cancer receiving FOLFOX chemotherapy were given standard antiemetic therapy (palonosetron 0.25 mg IV on day 1, dexamethasone 12 mg PO day 1, dexamethasone 8 mg PO day 2-4) plus aprepitant 125 mg PO day 1 and 80 mg PO day 2 and day 3 after chemotherapy. No comparison group.
PHASE OF CARE: Active anti-tumor treatment
One-group pre-/post-test design
Complete response (no emesis or rescue medications used), major response (no emesis but nauseated with or without rescue medication use), treatment failure (emesis within five days of chemotherapy using daily diary recording emetic events, nausea (0-100 mm visual analog scale), rescue medication use, as well as appetite and nutritional intake.
Overall CINV remained low throughout the chemotherapy cycles (CR = 74%, major response = 23%, failure = 4%). Appetite and nutritional status did not significantly change throughout treatment. Few adverse events were reported (diarrhea, 13.6%, fatigue, 12.6%, and neutropenia, 11%).
Aprepitant added to standard antiemetic therapy results in low CINV and has few adverse events. This regimen appears to be safe and effective for prevention of CINV in patients with colorectal cancer receiving FOLFOX. However, without a comparison group it is unclear if this antiemetic regimen is equal to or better than standard antiemetic therapy.
Aprepitant added to standard antiemetic therapy is safe and effective for preventing CINV in patients with colorectal cancer receiving FOLFOX, but may or may not be an improvement over standard antiemetic therapy alone.
