A Study Comparing the Efficacy and Safety of Orally Administered Ibuprofen and Placebo in Delayed Onset Muscle Soreness (DOMS)

December 1, 2015 updated by: Derek Muse, Jean Brown Research

A Double-Blind, Repeat-Dose, Parallel Group Study Comparing the Efficacy and Safety of Orally Administered Ibuprofen and Placebo in Delayed Onset Muscle Soreness.

The hypotheses to be tested are: Efficacy: Ibuprofen will be more effective than the Placebo in relieving muscle pain/soreness over 48 hour post-dosing with study medication. Safety: There will be no or minimal increased incidence of adverse events (AEs) with Ibuprofen versus and both will be well tolerated.

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.
Interventional

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.

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 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Placebo Comparator: Placebo
2 capsules identical to comparator, 3 times daily on Day 1 and Day 2. On Day 3 only one dose will be taken. The intervention is Acetaminophen 1000mg.
Drug: Acetaminophen 1000mg
Subjects who require rescue medication between hours 4 and 6 will be allowed to take Dose 2 of the study medication. If the subject chooses to take a rescue analgesic (acetaminophen 1000mg), they will be considered a treatment failure. This intervention will be use for the placebo and Ibuprofen arm.

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
Measure Description
Time Frame
SPID (Sum Pain Intensity Difference)
Time Frame: 0-48 hours
The primary efficacy parameter is muscle pain/soreness with movement at 48 hours (SPID 0-48)
0-48 hours

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.
