Antiemetic Fosaprepitant To Remedy Nausea and Vomiting

Brief Summary
The study team proposes a randomized, double-blind, RCT to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic ondansetron. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in EDs. Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time. The outcome for the efficacy analysis will be no need for additional medication to treat nausea and vomiting within 2 hours of investigational medication administration. The primary outcome for the tolerability analysis will be the development of any new symptom within 2 hours of medication administration.
Brief Title
Antiemetic Fosaprepitant To Remedy Nausea and Vomiting
Detailed Description
Nausea and vomiting (NV) are common and interrelated conditions. Approximately 50% of adults experience nausea in a given year while 30% of adults experience vomiting over the same period. Of this population of symptomatic individuals with NV, 25% of patients seek care in any healthcare delivery setting. Health Care Utilization Project (HCUP) data indicates that nearly 9.0 million patients seek care for NV in emergency departments (EDs) each year in the United States.

Antiemetics are used to treat NV. Antiemetics currently utilized in the emergency department setting for NV do not always work on the first dose and have a plethora of side effects because of their peripheral mechanism of action outside of the vomiting reflex pathway in the central nervous system. These medications include ondansetron, promethazine, metoclopramide, olanzapine, haloperidol. Chief among these side effects is alteration of an aspect cardiac electrical signaling called the QT segment which represents the duration of ventricular contraction and relaxation. The QT segment is prolonged with commonly used antiemetics which can often be a prelude to cardiac dysrhythmias that are associated with mortality. As a result, patients with NV often have long length-of-stay (LOS) involving supportive care with intravenous fluids or empiric treatment with medications that can potentiate development of cardiac dysrhythmias. This is a problem in busy emergency departments (EDs) struggling to accelerate patient throughput in order to appropriately keep up with patient volume in an under-supplied hospital bed environment nationally.

Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in EDs. Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time.

Official Title
Antiemetic Fosaprepitant To Remedy Nausea and Vomiting
Primary Outcomes
Outcome Description
Sustained relief from nausea and vomiting will be determined by the intensity of nausea reported by participants following administration of antiemetic. Intensity of nausea will be reported as either None, Mild, Moderate, or Severe. The number/percentage of participants reporting each degree of nausea intensity will be summarized

Sustained relief of nausea and vomiting requires a patient to present with a nausea intensity of either "severe" or "moderate," which is then reduced by treatment to at least "mild" or "none," within two hours of medication administration, and then maintained at "mild" or "none" level for the entire 24-hour period following medication administration without the use of rescue medication.
Outcome Measure
Sustained Relief from NV
Outcome Time Frame
24 hours (measured every 15 minutes for the first 2 hours, then hourly after that until disposition; reassessed at 24 hours)
Secondary Outcomes
Outcome Description
Freedom from nausea and vomiting (NV) will be determined by the intensity of nausea reported by participants following administration of antiemetic. Intensity of nausea will be reported as either "None," "Mild," "Moderate," or "Severe." Sustained freedom from nausea and vomiting requires a patient to present with a nausea intensity of either "Severe" or "Moderate," which is then reduced by treatment to "None" within two hours of medication administration. The number/percentage of patients with freedom from nausea/vomiting (NV) will be measured every 15 minutes for the first 2 hours. The number/percentage of patients with freedom from NV at 2 hours will be summarized by study arm.
Outcome Time Frame
2 hours following medication administration
Outcome Measure
Freedom from nausea and vomiting (NV)
Outcome Description
The number/percentage of patients demonstrating relief from nausea/vomiting (NV) will be measured every 15 minutes for the first 2 hours (for assessment of the primary outcome), then during every hour up to the end of the follow up period at 24 hours. Relief from NV is defined as achieving a level of relief of either "Mild" or None" at 2 hours and maintaining that level of "Mild" or "None" for the entire 24-hour period following medication administration, without use of rescue medication. The number/percentage of participants who achieve relief from NV will be summarized by study arm.
Outcome Time Frame
At 24-hours following medication administration
Outcome Measure
Sustained Relief from nausea and vomiting (NV) (at 24 hours)
Outcome Description
Sustained freedom from nausea and vomiting (NV) will be determined by the intensity of nausea reported by participants following administration of antiemetic. Intensity of nausea will be reported as either "None," "Mild," "Moderate," or "Severe." Sustained freedom from nausea and vomiting requires a patient to present with a nausea intensity of either "Severe" or "Moderate," which is then reduced by treatment to "None" within two hours of medication administration (corresponding secondary outcome), and maintained at this level (i.e., "None") for the entire 24-hour follow-up period, without the use or rescue medication. The number/percentage of participants who achieve sustained freedom from NV will be summarized by study arm.
Outcome Time Frame
At 24- hours following medication administration
Outcome Measure
Sustained NV Freedom (at 24 hours)
Outcome Description
A disposition determination plan will be documented at 4 hours. Patients will be categorized as either having been either "admitted," "discharged," or status "yet to be determined." Categorical data will be summarized by study arm.
Outcome Time Frame
4 hours following medication administration
Outcome Measure
Disposition Plan
Outcome Description
Medication preference will be assessed based on patient's preference for receiving the same antiemetic medication as administered for a subsequent episode of nausea and vomiting. Binary ("Yes" for having the same medication administered, "No" for request of a different medication) responses of patient preference will be summarized by study arm.
Outcome Time Frame
24 hours following medication administration
Outcome Measure
Patient Medication Preference for subsequent episode of NV
Outcome Description
ED LOS will be defined as the interval of time from initial presentation to final disposition in the ED, will be determined. Mean LOS results will be summarized by study arm.
Outcome Time Frame
