Brief Summary:
The principal objective of this multicenter, randomized, placebo-controlled trial is to evaluate whether 4 weeks of treatment with aprepitant will improve nausea as compared with placebo in patients with symptoms of chronic nausea and vomiting of presumed gastric origin.

Condition or disease Intervention/treatment Phase
Gastroparesis Drug: Aprepitant Drug: Placebo Phase 2

Detailed Description:

APRON is a multicenter, randomized, double-masked, placebo controlled trial of 4 weeks of treatment with aprepitant or placebo for patients with symptoms of gastroparesis and related disorders. Screening for eligibility and collection of baseline data will span up to 4 weeks after obtaining informed consent and registration. Eligible patients will consist of patients with symptoms of gastroparesis and will be randomized to either aprepitant (125 mg per day) or placebo for 4 weeks.

The symptoms will be measured with the Gastroparesis Cardinal Symptom Index Daily Diary (GCSIDD) for one week at baseline and for four weeks after randomization. In addition, the nausea symptom will be measured daily on a 0 to 100 mm visual analog scale (VAS) for one week at baseline and daily for four weeks after randomization. There will be a 2 week washout period at the end of the treatment to ensure patient safety following the end of treatment.

Bradygastria is when the rate of electrical activity in the stomach is <2.5 cycles per minute for at least 1 minute (a decrease in electrical activity in the stomach). The average power in frequency region is the percentage of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (here, baseline refers to the test performed during screening, not the baseline value of the EGG test) in percent of time with frequencies in the ranges, where negative values for bradygastria indicate improvement (less time in a dysrhythmic state).

Normal pacing is considered 2.5-3.7 cycles per minute (cpm). Bradygastria is when the rate of electrical activity in the stomach is <2.5 cycles per minute for at least 1 minute. Average power in frequency region is the % of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (baseline refers to test performed during screening, not baseline value of the EGG test) in % of time with frequencies in the ranges. Negative values for bradygastria indicate improvement (less time in a dysrhythmic state).

Normal pacing (normogastria) is considered 2.5-3.7 cycles per minute (cpm). The average power in frequency region is the percentage of time that the dominant EGG frequencies are in a given frequency: bradygastria, normal, tachygastria, or duodenal. The outcome measure is the change from baseline (baseline refers to the test performed during screening, not the baseline value of the EGG test) in percent of time with frequencies in the ranges, where positive values for normal rates indicate an increase in the normal pacing (improvement).
