A 4-week Study of Mifepristone in the Prevention of Risperidone-induced Weight Gain in Healthy Male Volunteers

February 4, 2022 updated by: Corcept Therapeutics

A 4-week, Double-blind, Placebo-controlled Study of the Efficacy and Safety of Mifepristone in the Prevention of Risperidone-induced Weight Gain in Healthy Male Volunteers

This is a 28-day, single-center, double-blind, placebo-controlled inpatient study of the administration of risperidone alone or in combination with mifepristone in healthy adult male volunteers to determine the average change in absolute weight at Day 28 compared to baseline.

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.

Detailed Description

This is a 28-day, single-center, double-blind, placebo-controlled inpatient study of the administration of risperidone alone or in combination with mifepristone in healthy adult male volunteers. The primary study objective is to determine the mean change in absolute weight at Day 28 compared to baseline in normal healthy male volunteers treated with risperidone plus mifepristone or risperidone alone. The secondary study objectives are to determine the mean percent change in baseline body weight; and the proportion of subjects that gain less than 5% and less than 7% of their baseline body in the treatment groups.

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.

Ages Eligible for Study

18 years to 40 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

  • Routine clinical laboratory tests either within normal limits or not clinically meaningful if outside of normal limits
  • AST, ALT, Tbili within normal limits at screening
  • Medical and psychiatric history and physical examination devoid of any significant findings that would interfere with participation or interpretation of results in this study
  • Agree to use a barrier method of birth control for 28 days following the last dose of study medication

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
Change From Baseline in Body Weight
Time Frame: Baseline and 28 days
Baseline and 28 days

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
Percentage of Participants With <5% and <7% Increase From Baseline in Body Weight
Time Frame: Baseline and 28 days
Baseline and 28 days
Percentage of Participants With One or More Adverse Events

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.
