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.

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.

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.

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
Change From Baseline in the 7-Day Average Daily Pain Score Using an 11-Point Scale
Time Frame: Baseline, Week 8
Participants recorded the pain in their knee during the previous 24 hours in a daily diary where: 0=no pain to 10= worst pain possible. The daily pain scores over 7-days were averaged. A negative change from Baseline indicates improvement.
Baseline, Week 8

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
Measure Description
Time Frame
Change From Baseline in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC™) Pain Score Using an 11-Point Scale
Time Frame: Baseline, Weeks 1, 4, 8, 12, 16, 20 and 24
The WOMAC Pain Score consisted of 5 questions about pain completed by the participant where: 0=no pain to 10=extreme pain for a total possible Pain Score of 0 (best) to 50 (worst). A negative change from Baseline indicates improvement.
Baseline, Weeks 1, 4, 8, 12, 16, 20 and 24
Change From Baseline in the WOMAC™ Physical Function Score Using an 11-Point Scale
Time Frame: Baseline, Weeks 1, 4, 8, 12, 16, 20 and 24
The WOMAC Physical Function Score consisted of 17 questions about the difficulty of daily activities completed by the participant where: 0=no difficulty to 10=extreme difficulty for a total possible Physical Function Score of 0 (best) to 170 (worst). A negative change from Baseline indicates improvement.
Baseline, Weeks 1, 4, 8, 12, 16, 20 and 24
Patient Global Impression of Change (GIC) Using a 7-Point Scale
Time Frame: Weeks 1, 4, 8, 12, 16, 20 and 24
The participant rated the change in their health status since enrollment using a 7-point scale where: +3=very much improved, +2=much improved, +1=minimally improved, 0=no change, -1=minimally worse, -2=much worse and -3=very much worse. Negative scores indicate worsening and positive scores indicate improvement.
Weeks 1, 4, 8, 12, 16, 20 and 24
Change From Baseline in the 7-Day Average Daily Worst Pain Score Using an 11-Point Scale
Time Frame: Baseline, Week 24
Participants recorded the pain in their knee during the previous 24 hours in a daily diary where: 0=no pain to 10= worst pain possible. The daily worst pain scores over 7-days were averaged. A negative change from Baseline indicates improvement.
Baseline, Week 24

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

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.
