June 16, 2009 updated by: Procter and Gamble

A Phase II, Randomized, Adaptive Design, Multicenter, Parallel Group, Placebo-Controlled, 58 Day, Dose-Ranging Study of ATI 7505 in Patients With Postprandial Distress Syndrome

To assess the efficacy of 3 oral dosing regimens of ATI 7505 compared to placebo in patients with PDS by comparing at the end of Day 42 the percentage of patients in each treatment group who have had adequate relief of postprandial distress syndrome symptoms on at least 50% of the treatment days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Were diagnosed with PDS at least 6 months prior to screening, OR had onset of 2 or more PDS symptoms at least 6 months prior to screening.
  • Experienced early satiety or bothersome postprandial fullness repeatedly during the 3 months prior to screening.
  • Had a normal upper GI endoscopy within the past year.

Exclusion Criteria:

  • Heartburn that occurs >3 times per week
  • Current Helicobacter pylori (H pylori) infection confirmed by stool sample testing or breath testing, or H pylori eradication therapy within the 6 months prior to screening
  • Any alarm symptoms including uninvestigated anemia, rectal bleeding, weight loss, or unresolved fever within the 6 months prior to screening

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Efficacy of 3 oral dosing regimens of ATI 7505 vs. placebo in patients with PDS.
Time Frame: Day 42
Day 42

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Safety and tolerability of ATI 7505
Time Frame: 42 days
42 days
Time to recurrence of the 2 primary PDS symptoms at day 42
Time Frame: 42 days
42 days
Effect of ATI 7505 treatment on quality of life indices

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2008

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
