Methods: This clinical trial study was conducted on 120 patients in the age range of 5 to 18 years old who received chemotherapy. Patients were divided into two groups; Group A received aprepitant at 125 mg/kg on day 1 orally, followed by 80 mg/kg daily on days 2 and 3 and Group B received a single dose of aprepitant 125 mg/kg on day 1 orally and placebo on days 2 and 3. All groups received granisetron 3 mg/m2 on day 1 and DEX on days 1 to 3. The primary and secondary endpoints were to evaluate the proportion of patients with acute, delayed and overall CINV within each group. Results: There were no significant differences between the two groups for vomiting, nausea or the use of rescue therapy. The number of patients without vomiting on day 1 was similar in both groups (96.5%vs. 98.3%, respectively; p=0.848).

This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/).TaggedEnd TaggedH1IntroductionTaggedEnd TaggedPChemotherapy-induced nausea and vomiting (CINV) are one of the distressful effects of chemotherapy, which may result in the patient’s anxiety and depression. These two symptoms are the first and second most-feared side effects of chemotherapy. The pathophysiology of CINV is highly complicated and it will significantly disturb the life quality of patients with cancer.1,2 Combination therapy of 5-hydroxytryptamine-3 (5HT3) receptor antagonists with dexamethasone (DEX) has a significant effect on acute CINV.3 The most common standard therapy for CINV control in children is the use of antagonists of receptor 5-HT3 in combination, with or without a corticosteroid.4,5 TaggedEnd TaggedPThe5-HT3 receptor antagonists include dolasetron, ondansetron, palonosetron, tropisetron and granisetron.6 Granisetron (Kytril) is a selective 5-HT3 receptor antagonist which is recommended by clinical practice guidelines as an effective and potent antiemetic drug.7 Application of antagonists of receptor 5-HT3, along (Shouldn’t this be “prolonged”???) with DEX, can improve CINV in the acute stage, but the delayed CINV has remained an important clinical issue.8,9 TaggedEnd TaggedPAprepitant is one of the drugs approved by the FDA for the control of acute and chronic CINV which acts as a neurokinin 1 (NK1) receptor antagonist.10 Regarding its pharmacokinetics, it requires lower doses of DEX, which has distinguished it from other groups. The side effects of this group are also negligible, compared to other groups.11 Aprepitant has been approved for use in combination with a selective 5 HT3−receptor antagonist, such as granisetron, in adults.12 These patients, undergoing highly emetogenic chemotherapy (HEC) with uncontrolled CINV, usually require longer hospitalization, but the combined effects of granisetron and aprepitant in the prevention of CINV in children undergoing chemotherapy have been less studied. This clinical trial was performed to evaluate the degree of 3-day CINV in children with cancer undergoing HEC to ascertain the efficacy of aprepitant single-dose on day 1 plus granisetron and DEX versus aprepitant on days 1 to 3, in combination with granisetron and DEX.TaggedEnd TaggedH1Methods and materialsTaggedEnd TaggedH2Study populationTaggedEnd TaggedPA randomized, triple-blind clinical trial was performed, enrolling 176 children in the age range of 5 to 18 years old TaggedEndTaggedPwho were chemotherapy candidates for acute lymphoblastic leukemia, rhabdomyosarcoma, Wilms tumor, acute myeloid leukemia, osteosarcoma and hepatocellular carcinoma at the Amir-Kabir Hospital in Arak, Iran. This study was a retrospective observational study over a 12-month period.TaggedEnd TaggedPThese patients were scheduled to receive an HEC (Doxorubicin, Cyclophosphamide, Vincristine, Cisplatin, Dacarbazine, Vinblastine, Bleomycin and Actinomycin D). The enrollment of participants, as well as the allocation and allocation of intervention instructions, was performed by a pediatrician and researcher. Randomization was performed using random number generation in Excel software; each patient had an identical number (ID) based on the visiting sequence and these IDs were entered into the Excel software. Thereafter, the“RAND” function was included in another column and the RAND function was entered for each patient, which automatically generated random numbers in Excel rows. After applying the ascending sorting, the random numbers and the patient IDs positions were changed randomly. The sorted IDs were divided into two groups. This study was approved by the Ethics Committee of Arak University of Medical Sciences (ethical committee code number: IR.ARAKMU.REC.1396.46). The trial was registered at the Iranian Registry of Clinical Trials as IRCT20100127003210N19. The inclusion criteria included the following: the presence of cancer confirmed by the molecular assays and histopathological examination; patients who had not received chemotherapy or radiotherapy for 6 months prior to the study; patients who did not have other clinical features, such as anemia, leukopenia and thrombocytopenia; patients who had other disorders causing CINV, such as hypocalcemia, central nervous system malignancy and gastrointestinal disorders; patients who did not have uncontrolled diabetes; patients with normal liver and kidney function, and; patients with normal immune systems. Furthermore, patients with hypertension, fever, severe infection, tinnitus and cardiovascular disease and patients with respiratory problems were excluded from this study. Based on the type of study, the sample size was calculated using Pass 11 software with type I (a) error left at 5 % and type II (b) error left at 20 %, and study power of 90%. The mean§standard deviation (SD) was 10.6 §0.6 in group A and 11.3 §0.4 in group B. The sample size of 51 patients was determined for each group, but considering the possibility of some patients missing, the minimum sample size of 57 was considered.TaggedEnd TaggedH2Therapeutic protocolTaggedEnd TaggedPEligible children received HEC, including cisplatin, anthracycline and cyclophosphamide combinations (e.g., fluorouracil, TaggedEnd282 hematol transfus cell ther. 2023;45(3):281−289

For all principal researchers, patients, and study evaluators, except for the experienced trained physician of the AmirKabir Hospital, randomization was blinded (triple-blinded) to the study. Study bias, through masking the patients and study evaluator, was reduced. After obtaining informed written consent and based on the anti-emetic treatment regimen, patients were divided into group A, 60 patients who received aprepitant at 125 mg/kg on day 1 orally, followed by 80 mg/kg daily on days 2 and 3, a single dose of granisetron at 3 mg/m2 intravenously (i.v.) on day 1, half an hour before HEC, along with 0.1 mg/kg of DEX on day 1 and 0.1 mg/kg daily on days 2 and 3, 1 hour before HEC and group B, 60 patients who received a single dose of aprepitant 125 mg/kg on day 1 orally and placebo on days 2 and 3, a single dose of granisetron 3 mg/m2 (i.v.) on day 1, along with 0.1 mg/kg of DEX orally on day 1, and 0.1 mg/kg daily on days 2 and 3, 1 hour before HEC. The shape and size of the placebo drugs were similar to those of the original drugs. Patients were asked not to discontinue or alter medication during the study. Information on the patient chemotherapy history (naive or non-naive to TaggedEndTaggedPchemotherapy) was extracted from their records. There had been a 6-month chemotherapy-free period since the prior chemotherapy of the patients who had a history of chemotherapy and these patients did not have CINV at the time of the study. Figure 1 summarizes the doses and administrative sequences of antiemetics.TaggedEnd TaggedH2Evaluation of CINVTaggedEnd TaggedPA single emetic episode was considered as at least one episode of vomiting, separated by less than a 5-minute interval, during the current chemotherapy cycle. Nausea is a feeling in the stomach that may be accompanied by vomiting. The severity of nausea was assessed by using a visual analogic scale (VAS), ranging from 0 to 100 mm (VAS < 5mm = least severe [no nausea], VAS < 25mm = no significant nausea, 100 = most severe). Patients were asked to record in a diary the number of emetic episodes and the severity of nausea during the 72 hours following chemotherapy. A coordinator had conversations with patients during these three days to ensure that patients recorded all cases of vomiting and nausea correctly.

In other words, the use of a single dose of aprepitant protects against vomiting in more than 90% of patients and nausea in more than 80% of patients. Previous studies have shown that adding aprepitant to standard treatment improves CR rates, compared to standard treatment in acute, overall and delayed phases.13,14 Hesketh et al. reported that the use of aprepitant in addition to the standard dual therapy, compared to the standard therapy, only improved the rate of CR in the acute TaggedEndTaggedP(78% vs. 89%), delayed (55% vs. 75%) and overall phases (52% vs. 72%).15 Similar results were reported in our study Figure 5.TaggedEnd TaggedPIn accordance with our results, DiIorio et al. reported that a single dose of aprepitant reduced the number of episodes and severity of nausea and vomiting, the need for additional antiemetics and the length of stay.16 Furthermore, Saito et al. reported that aprepitant was safely used and may be equally useful for pediatric patients receiving HEC,17 which was consistent with the results of our study.TaggedEnd TaggedEnd TaggedFigure Figure4–The proportion of patients without rescue therapy during days 1 - 3 after HEC.

TaggedPThe CINV is one of the undesirable side effects of chemotherapy regimens for patients with cancer. Therefore, to improve the quality of life of patients receiving chemotherapy, it is necessary to assess the severity of the CINV. The effect of aprepitant-containing antiemetics in children receiving chemotherapy drugs in this study is similar to that in other studies.TaggedEnd TaggedPJanelsins et al. reported that the application of serotonin receptor antagonists, along with DEX, can improve the CINV in the acute stage, but the delayed N/V has remained an important clinical issue.18,19 Aprepitant is one of the drugs approved by the FDA for the treatment of CINV in March 2003. Aprepitant is effective in preventing acute and chronic CINV in patients undergoing HEC, including cisplatin- and anthracycline-containing therapies.20 TaggedEnd TaggedPHerrington and colleagues reported a comparison trial with aprepitant, combined with palonosetron and DEX, in patients who were 18 years of age or older.21 Their Arm A TaggedEndTaggedPpatients received aprepitant 125 mg orally on day 1, followed by 80 mg orally on days 2 and 3, while Arm B received only aprepitant 125 mg orally on day 1 and placebo on days 2 and 3. All groups received palonosetron 0.25 mg (i.v.) on day 1, plus DEX on days 1 to 4. However, there were no statistical differences for emesis, nausea or the use of breakthrough antiemetic medication between Arm A and Arm B,21 whichwas consistent with our findings. In Arms A and B, 93% of the patients were vomiting-free from days 1 to 5,21 compared to 91.5% and 94.8%, respectively, in our study.TaggedEnd TaggedPIn another study, Oyama et al. evaluated the efficacy of aprepitant at 285 mg in patients with gastric cancer (median age 65 years) treated with S-1, plus cisplatin, for the prevention of CINV.22 They prescribed aprepitant at 125 mg orally 60 min before the cisplatin infusion, granisetron at 3 mg (i.v.) 30 min and DEX at 9.9 mg (i.v.) on day 1; oral aprepitant at 80 mg daily along with oral DEX at 8 mg on days 2 and 3, and; oral DEX at 8 mg on day 4.

In addition, the proportions of patients without significant nausea (VAS < 25) during the acute, delayed and overall periods were 98.1%, 69.8% and 69.8%, respectively. The proportions of patients without rescue therapy were 96.2%, 100% and 96.2 in the overall, acute and delayed periods, respectively.22 TaggedEnd TaggedPIn a study, Grunberg et al. evaluated the efficacy of a single daily dose of aprepitant at 285 mg in patients with solid tumors for the prevention of acute and delayed CINV.23 They prescribed a single dose of aprepitant at 285 mg orally, along with palonosetron and DEX, to breast cancer patients with a median age of 52 years who were to undergo a chemotherapy regimen with cyclophosphamide and anthracycline. The CRs were 78%, 59%, and 50% in the acute, delayed and overall periods, respectively. The percentage of patients without vomiting during the first 24 hours was 100% and for the delayed and overall phases, 97% and 97, respectively. Additionally, the percentages of patients without significant nausea (VAS< 25) during the acute, delayed and overall periods were 75, 62% and 56%, respectively.23 However, it should be noted that the use of larger doses of aprepitant may interfere with chemotherapy drugs, such as cyclophosphamide and doxorubicin.TaggedEnd TaggedPIn a study on the efficacy of aprepitant and fosaprepitant in CINV in 26 children and teenagers with cancer (who were 11 months to 17 years), the authors found that the use of aprepitant and fosaprepitant had optimal effectiveness on decreasing CIVN, which was similar to the results of this study.24 In another study in patients aged 6 months to 17 years being treated with emetogenic chemotherapy, the authors recorded that the combination of aprepitant with ondansetron, with or without DEX, was useful in the prevention of CINV.25 Thesefindings were, to some extent, similar to the results of this study and the limited difference could be attributed to the difference in the evaluated groups. In a study on the efficacy of aprepitant in the CINV of children suffering from cancer, the authors showed that aprepitant can be employed as a standard treatment for children suffering from severe CINV.26 Megan et al. showed that aprepitant appeared to be safe and well-tolerated in children weighing less than 40 kg, but that it might not completely reduce the CINV.27 In this study, it was shown that the combination of granisetron and aprepitant could render most patients CINV-free during days 1 to 3 after chemotherapy.TaggedEnd TaggedPIn a double-blinded randomized clinical trial, Kang et al. assessed the efficacy of aprepitant on the CINV of children suffering from cancer who were also undergoing chemotherapy. Their results revealed that the 3-dose oral aprepitant, in combination with ondansetron, with or without DEX, can significantly prevent the CINV in children undergoing chemotherapy, when compared with controls or those treated solely with ondansetron, with or without DEX.28 Shillingburg et al. conducted a study addressing the efficacy of aprepitant and fosaprepitant on the CINV among 26 children and teenagers with cancer. They reported no side effects due to the administration of aprepitant and, hence, they concluded that aprepitant and fosaprepitant could be well tolerated in children.29 No serious side effects were seen in this study.TaggedEnd TaggedH1ConclusionTaggedEnd TaggedPIn conclusion, the current study has shown that a single dose of aprepitant of 125 mg/kg was as effective as administering three doses of aprepitant over 3 days. Therefore, using a single dose of aprepitant of 125 mg/kg is less expensive and has similar efficacy for HEC regimens. Furthermore, the use of a single dose of aprepitant, in combination with other standard treatment regimens, to prevent the CINV in children who received highly emetogenic chemotherapy was safe and efficacious and could be beneficial.TaggedEnd TaggedH1Conflicts of interestTaggedEnd TaggedPNone.TaggedEnd TaggedH1AcknowledgmentsTaggedEnd TaggedPWe would like to thank the Research Council of Arak University of Medical Sciences, which has provided funding for this research (Grant 1719).
