Study to Assess the Efficacy of VLY-686 in Relieving Symptoms of Gastroparesis

Phase 2

Completed

• Conditions: Gastroparesis
• Interventions: Other: Placebo; Drug: VLY-686 (Tradipitant)

• Registration Number: NCT02970968
• Lead Sponsor: Vanda Pharmaceuticals

Brief Summary

This is a multicenter, randomized, double-blind, placebo-controlled study to be conducted in the United States. One hundred fifty (150) subjects diagnosed with gastroparesis, who satisfy the selection criteria for the study, will be randomized to one of two treatment groups, active or placebo.

Detailed Description

This is a multicenter, randomized, double-blind, placebo-controlled study to be conducted in the United States. One hundred fifty (150) subjects diagnosed with gastroparesis, who satisfy the selection criteria for the study, will be randomized to one of two treatment groups, active or placebo.

The study is divided into two phases: the screening phase and the evaluation phase. The screening phase includes a screening visit to evaluate subjects' preliminary eligibility for the study. During the screening phase, subjects will collect diary data for at least 4 weeks. The evaluation phase includes 4 weeks of randomized double-blind treatment.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Placebo oral capsule for 4 weeks.
Study Drug	VLY-686 (Tradipitant)	VLY-686 (Tradipitant) oral capsule for 4 weeks.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Average Nausea Severity	4 weeks	The Gastroparesis Core Symptom Daily Diary (GCSDD) is a patient reported diary that asks patients to rate the worst occurrence of each cardinal symptom of gastroparesis (nausea severity, early satiety, postprandial fullness, bloating, and abdominal pain) in the past 24 hours on a Likert scale from 0 (no symptoms) to 5 (very severe). Change from baseline in average nausea severity score is calculated as the weekly average post value minus baseline value of the daily nausea severity score from the GCSDD. A negative change indicates improvement.

Secondary Outcome Measures

Name	Time	Method
PAGI-SYM, Change From Baseline	4 weeks	The PAGI-SYM is a patient reported outcome which asks patients to describe the severity of their symptoms over the last two weeks to measure symptom severity for gastroparesis, functional dyspepsia, and gastroesophageal reflux disease. The measure consists of 20 symptom severity items, which cover the following domains: nausea/vomiting, fullness/early satiety, bloating, upper abdominal pain, heartburn/regurgitation, and lower abdominal pain. This questionnaire includes the Gastroparesis Cardinal Symptom Index (GCSI). The severity of each symptom is rated on a six-point Likert response scale. The minimal scale value = 0 (none) and the maximum scale value= 5 (very severe). PAGI-SYM Total score is constructed as the average of the six symptom sub-scales and a higher score is indicative of greater symptom severity.
Daily Average Vomiting Frequency, Change From Baseline	4 weeks	The Gastroparesis Core Symptom Daily Diary (GCSDD) is a patient reported diary that asks patients if they have vomited in the past 24 hours and how many times they vomited in the past 24 hours. Change from baseline in the weekly average of daily vomiting frequency is calculated as the weekly average post value minus baseline value of the daily daily vomiting frequency from the GCSDD. Baseline is defined as the average of all non-missing values in the screening phase (4 weeks). A negative change indicates improvement.
Weekly % Nausea-Free Days	4 weeks	The Gastroparesis Core Symptom Daily Diary (GCSDD) is a patient reported diary that asks patients if they have had any nausea over the past 24 hours and if yes, to rate the worst occurrence in the past 24 hours on a Likert scale from 1 (very mild) to 5 (very severe). Change in weekly percentage of nausea-free days from baseline is calculated as weekly average post value minus baseline value. Baseline is defined as the average of all nonmissing values in the screening phase (4 weeks).
CGI-S, Change From Baseline	4 weeks	The Clinician Global Impression of Severity (CGI-S) is a 7-point scale on which the clinician rates the severity of the patient's gastroparesis at the time of the assessment and refers to the degree of illness at the time of the visit and during the 2 weeks before the visit. The CGI-S is rated on the following 7-point scale: 1: normal, not at all ill; 2: borderline ill: 3: mildly ill; 4: moderately ill; 5: markedly ill; 6: severely ill; 7: among the most extremely ill patients. Change from baseline is calculated as post value minus baseline value. A negative change indicates improvement.
Gastroparesis Cardinal Symptom Index (GCSI), Change From Baseline	4 weeks	The GCSI is a subject reported outcome administered in-clinic with a 2-week recall period to measure the severity of symptoms in gastroparesis. The GCSI is composed of 9 items based on three subscales: post-prandial fullness/early satiety (4 items); nausea/vomiting (3 items), and bloating (2 items). The severity of each symptom is rated on a six-point Likert response scale. The minimal scale value = 0 (none) and the maximum scale value = 5 (very severe). GCSI Total score is constructed as the average of the three symptom sub-scales. Higher score is indicative of greater symptom severity.
PGI-C	4 weeks	The Patient Global Impression of Change (PGI-C) is a patient reported questionnaire with a 7-point rating scale where the participant rates his/her own improvement in overall symptoms relative to the baseline assessment. Is is rated as 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. Higher scores indicate a worse outcome.
