Meta-analysis of Orlistat Laboratory Data From Placebo-controlled Clinical Trials

June 1, 2017 updated by: GlaxoSmithKline
Roche and GSK will carry out a meta-analysis of liver function data from trials of orlistat to establish whether there is any indication of liver toxicity. The motivation is a cumulative assessment of drug-induced liver injury (DILI) conducted by the FDA following spontaneous reports of liver toxicity in people taking Xenical or Alli.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

All clinical trials found by search procedure:

  1. In-house trial repositories at GSK and Roche
  2. EMBASE (which includes MEDLINE) using the terms "orlistat", "Xenical" or "Alli", with "placebo" and "clinical trial"
  3. Recently published meta-analyses found by the search will also be searched for relevant trials

Description

Inclusion Criteria:

  1. The trial must be randomized and placebo-controlled
  2. The orlistat dose must be 60mg or 120mg
  3. Data on ALT or BIL must be available
  4. The nominal treatment period must be 16 weeks or longer

Exclusion Criteria:

1. If cross-over trials are found, data from other than the first period will be excluded.

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
Odds ratio (Orlistat120:Placebo) for subjects experiencing alanine transaminase (ALT) greater than upper limit of normal (ULN)
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat120:Placebo) for subjects experiencing total bilirubin (BIL) > ULN
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat120:Placebo) for subjects experiencing ALT > ULN for successive measurements more than two weeks apart
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat120:Placebo) for subjects experiencing BIL > ULN for successive measurements greater than two weeks apart
Time Frame: within one year of starting treatment
within one year of starting treatment

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
Odds ratio (Orlistat60:Placebo) for subjects experiencing ALT > ULN
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat60:Placebo) for subjects experiencing BIL > ULN
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat60:Placebo) for subjects experiencing ALT > ULN for successive measurements more than two weeks apart
Time Frame: within one year of starting treatment
within one year of starting treatment
Odds ratio (Orlistat60:Placebo) for subjects experiencing BIL > ULN for successive measurements greater than two weeks apart
Time Frame: within one year of starting treatment
within one year of starting treatment

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, 2010

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.
