What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility of Recruitment and Enrollment
Recruitment and enrollment feasibility will be assessed as the proportion of the planned sample enrolled within 6 months of initiating recruitment. The planned sample size is 30 participants. Feasibility will be demonstrated if the full planned sample is enrolled within 6 months.
Measured: From initiation of recruitment through 6 months.
Acceptability of Intervention Procedures as Assessed by the Theoretical Framework of Acceptability Questionnaire (TFA)
Acceptability of the assigned intervention and study procedures will be assessed using a questionnaire based on the Theoretical Framework of Acceptability (TFA). The TFA assesses domains including affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy.
Measured: Through completion of the 33-day at-home intervention period.
Completeness of Laboratory Visit Outcome Data
Laboratory data completeness will be assessed as the percentage of scheduled laboratory outcome assessments successfully completed during the 3-hour post-intervention laboratory period. Scheduled assessments include pain ratings, Timed Up and Go testing, and stair-climb testing. Feasibility will be demonstrated if at least 80% of scheduled laboratory outcome data are complete.
Measured: During the 3-hour post-intervention laboratory period.
Completeness of Follow-Up Data (Retention)
Follow-up data completeness will be assessed as the percentage of scheduled follow-up assessments completed by enrolled participants. Feasibility will be demonstrated if at least 80% of scheduled follow-up data are completed.
Measured: Through 6 months post-intervention.
Secondary outcomes (6)
Post-Randomization Treatment Expectancy
Treatment expectancy will be assessed following randomization and before administration of the assigned intervention. Participants will rate how much benefit or improvement they expect from the assigned intervention. Higher scores indicate greater expected benefit from the assigned intervention.
Measured: Immediately prior to intervention exposure at laboratory visit; post-randomization.
Post-Intervention Treatment Credibility
Treatment credibility will be assessed after intervention administration. Participants will rate how credible the assigned intervention seems as a pain-management strategy. Higher scores indicate greater perceived treatment credibility. Credibility will be assessed at 30 minutes and 3 hours post-intervention.
Measured: 30 minutes and 3 hours post-intervention.
Adverse Events During the Laboratory Period
Adverse events will be assessed through direct observation and standardized safety queries during the laboratory visit. The outcome will be the number of participants experiencing one or more adverse events during the 3-hour post-intervention laboratory period.
Measured: Intervention onset through 3 hours post-intervention.
Change in Acute Pain Intensity
Acute pain intensity will be assessed using a participant-reported 0-10 Numeric Rating Scale, with 0 indicating no pain and 10 indicating the worst pain imaginable. Higher scores indicate greater pain intensity. Change in pain intensity will be evaluated from the pre-intervention baseline through repeated assessments during the 3-hour post-intervention laboratory period.
Measured: Pre-intervention baseline through 3 hours post-intervention.
Timed Up and Go Test (TUG)
Physical function will be assessed using the Timed Up and Go Test. Participants begin seated in a standard chair, stand, walk 3 meters, turn around, return to the chair, and sit down. Time to task completion is recorded in seconds, with lower times indicating better physical function. The outcome will be the average completion time across the two Timed Up and Go trials performed during the 3-hour laboratory period.
Measured: During the 3-hour post-intervention laboratory period.
Stair-Climb Task
Physical function will be assessed using a timed stair-climb task on a standardized flight of 12 stairs. Participants ascend and descend the stairs, and task completion time is recorded in seconds, with lower times indicating better physical function. The outcome will be the average completion time across the two stair-climb trials performed during the 3-hour laboratory period.
Measured: During the 3-hour post-intervention laboratory period.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Oral diclofenac potassium 50 mg and Mindfulness meditation in people with Knee Osteoarthristis, run by Florida State University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 23 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility of Recruitment and Enrollment (time frame: From initiation of recruitment through 6 months.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2026.
