The subject must be excluded from participating in the trial if:;Exclusion criteria for Cycle 1 only:;1.has vomited in the 24 hours prior to chemotherapy initiation on Treatment Day 1.;2.has a symptomatic primary or metastatic central nervous system (CNS) malignancy with nausea and/or vomiting. Subject who is asymptomatic is allowed to participate.;3.has abnormal laboratory values as follows:;•peripheral absolute neutrophil count (ANC) <1000/mm3;•platelet count < 75,000/mm3;•aspartate aminotransferase (AST) > 5.0 x upper limit of normal (ULN) for age;•alanine aminotransferase (ALT) > 5.0 x ULN for age;•bilirubin > 1.5 x ULN for age;•creatinine > 1.5 x ULN for age;4.will be receiving stem cell rescue therapy in conjunction with study related course of emetogenic chemotherapy or during the 14 days following administration of fosaprepitant/placebo for fosaprepitant. ;5.has received or will receive total body irradiation or radiation therapy to the abdomen (includes the level of the diaphragm and below) or pelvis in the week prior to Treatment Day 1 and/or during the diary reporting period (120 hours following initiation of chemotherapy).;6.has had benzodiazepine (potential to alleviate nausea and vomiting), opioid or opioid like (e.g., tramadol hydrochloride) therapy (potential to enhance nausea and vomiting) initiated within 48 hours prior to study drug administration, or is expected to receive within 120 hours following initiation of chemotherapy, except for single daily doses of midazolam, temazepam or triazolam. Continuation of chronic benzodiazepine, opioid or opioid like therapy is permitted provided it was initiated at least 48 hours prior to study drug administration.;7.has been started on systemic corticosteroid therapy within 72 hours prior to study drug administration or is expected to receive a corticosteroid as part of the chemotherapy regimen.;Exceptions:;subject who is receiving chronic (>72 hours), daily steroid therapy can be enrolled provided the steroid dose is not >0.14 mg/kg (up to 10 mg) of prednisone daily or equivalent.;for supportive care, subject is permitted to receive a single dose of corticosteroid within 3 days prior (but not on the day of study drug administration) provided it is less than the equivalent of 20 mg of prednisone.;8.is currently taking, or has taken within 48 hours of Treatment Day 1 the following drugs with antiemetic properties: 5-HT3 antagonists (e.g., ondansetron), benzamides (e.g., metoclopramide), butyrophenones (e.g., haloperidol), cyclizine, domperidone, herbal therapies with potential antiemetic properties, olanzapine, phenothiazines (e.g., prochlorpenzine), scopolamine. ;Exclusion criteria for Cycle 1 and optional Cycles 2 to 6:;9.is or has an immediate family member (e.g., spouse, parent/legal guardian, sibling or child) who is investigational site or sponsor staff directly involved with this trial. ;10.is currently a user of any recreational or illicit drugs (including marijuana) or has current evidence of drug or alcohol abuse or dependence as determined by the investigator.;11.is mentally incapacitated or has a significant emotional or psychiatric disorder that, in the opinion of the investigator, precludes study entry.;12.is pregnant or breast feeding. ;13.is allergic to fosaprepitant, aprepitant, ondansetron, or any other 5-HT3 antagonist.;14.has a known history of QT prolongation or is taking any medication that is known to lead to QT prolongation. ;15.has an active infection

Name Time Method <p>The single IV dose of fosaprepitant in combination with ondansetron with or<br /><br>without dexamethasone (hereafter referred to as the fosaprepitant regimen)<br /><br>provides superior control of CINV compared to ondansetron alone with or without<br /><br>dexamethasone (hereafter referred to as the control regimen) as measured by the<br /><br>proportion of subjects with Complete Response (no vomiting, no retching, and no<br /><br>use of rescue medication) in the delayed phase (>24 to 120 hours) following the<br /><br>initiation of emetogenic chemotherapy in Cycle 1.</p><br>
- Secondary Outcome Measures
Name Time Method <p>- The fosaprepitant regimen is superior to the control regimen as measured by<br /><br>the proportion of subjects with Complete Response in the acute phase (0 to 24<br /><br>hours) following the initiation of emetogenic chemotherapy in Cycle 1.<br /><br>- The fosaprepitant regimen is superior to the control regimen as measured by<br /><br>the proportion of subjects with Complete Response in the overall phase (0 to<br /><br>120 hours) following the initiation of emetogenic chemotherapy in Cycle 1.<br /><br>- The fosaprepitant regimen is superior to the control regimen as measured by<br /><br>the proportion of subjects with No Vomiting, regardless of rescue medication<br /><br>use, in the overall phase (0 to 120 hours) following the initiation of<br /><br>emetogenic chemotherapy in Cycle 1.</p><br>
