Effect of Dietary Components on Gastrointestinal Side Effects Induced by Orlistat, a Lipase Inhibitor (ORLIFAT)

September 1, 2014 updated by: Arne Astrup, University of Copenhagen

The objective of the Orlifat trial is to investigate if dietary fibres from linseeds and dairy calcium (Capolac ®) may reduce gastrointestinal side effects related to increased fecal fat content, induced by treatment with Alli® (orlistat). Secondly, effect on food intake, anthropometry, Quality of Life and cardiovascular risk markers will be evaluated. The trial is designed as a randomised 2 x 2 factorial 13-weeks parallel intervention, in which 72 obese participants will be randomised to supplementation with flaxseed fibres and/or dairy calcium concentrate (Capolac) in addition to treatment with Alli ®:

  1. Alli® (60 mg t.i.d) plus placebo (rice flour)
  2. Alli® plus 5 g flaxseed fibers
  3. Alli® plus 1200 mg Ca from Capolac
  4. Alli® plus 5 g flaxseed fibers and 1200 mg Ca from Capolac

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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.

Secondary Outcome Measures

Secondary Outcome Measures
