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
Number and Severity of Adverse Events (All Causalities); Baseline to Final Visit (Week 4)
Time Frame: Baseline through Final Visit (Week 4)
Number and severity of adverse events, including serious adverse events. If the same subject had more than one occurance in the same preferred term event category, only the most severe occurrence was taken.
Baseline through Final Visit (Week 4)
Discontinuations Due to Adverse Events
Time Frame: Baseline, Second Visit (Week ≥ 2), Final Visit (Week 4)
Discontinuations due to adverse events by MedDRA system organ class and preferred term.
Baseline, Second Visit (Week ≥ 2), Final Visit (Week 4)

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 Visual Analogue Scale (VAS) Score
Time Frame: Baseline, Second Visit (Week ≥ 2), Final Visit (Week 4)
Change from Baseline in 10 cm VAS pain score; 10-point pain intensity ordinal rating system: 0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, 7-9 = severe pain, 10 = worst possible pain. Change = scores at second visit and final visit minus score at Baseline.

Shift table shows the number of subjects with each pain intensity rating at the Second Visit by the number of subjects with each pain intensity rating at Baseline. Abbreviations: mod = moderate, sev = severe, wrst = worst, poss = possible, pn = pain, vst = visit .

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.
