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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • At least 18 years of age
  • Diagnosed with nail psoriasis in at least 2 fingernails

  • Must consent to having the fingernails photographed during the study period

Exclusion Criteria:

  • Subject with any clinically significant condition or situation, other than the condition being studied that, in the opinion of the investigator, would interfere with study evaluations or optimal participation in the study. This is including, but not limited to: immunodeficiency, onychomycosis, any other nail condition other than psoriasis, allergy to triamcinolone acetonide, local anesthetic, normal saline, or any other material used for procedures
  • Subject who has received radiation therapy, chemotherapy, and/or immunosuppressive drugs within 6 months of study, and/or oral corticosteroids for >1 month within the 6 months of study (exception: inhaled steroids)
  • Subject known to have received treatment with investigational drugs or devices within 30 days prior to enrollment into this study
  • Subject who is unwilling to abstain from any cosmetic nail treatments outside those provided by the study clinic, beyond basic nail trimming (i.e. no spa nail treatments, no nail polish use, no other topical prescription nail medication)
  • Subject who is unwilling to abstain from any medical nail treatments on their nails other than the study intervention (i.e. topical steroids, anti-fungal creams) for the duration of the study intervention and for duration of the washout period (if applicable)
  • Subject who is part of the staff personnel directly involved with this study or a family member of the investigational study staff

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
Lowest Effective Concentration of Intralesional Triamcinolone Acetonide for Nail Psoriasis
Time Frame: 24 weeks (end of study)
The most effective concentration of intralesional triamcinolone acetonide will be determined between 0 mg/mL, 2.5 mg/mL, 5.0 mg/mL, 7.5 mg/mL, and 10.0 mg/mL.
24 weeks (end of study)

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 Nail Psoriasis, as Measured by Nail Psoriasis Severity Index (NAPSI)
Time Frame: Baseline, 24 weeks (end of study)
The Nail Psoriasis Severity Index (NAPSI) is used to evaluate nail psoriasis. Scores range from 0 to 8 with 0 indicating no nail psoriasis and higher scores indicating worsening nail psoriasis.
Baseline, 24 weeks (end of study)
Change From Baseline in Nail Psoriasis Qualify of Life, as Measured by Development and Validation of Nail Psoriasis Quality of Life Scale (NPQ10)
Time Frame: Baseline, 24 weeks (end of study)
The NPQ10 comprises 10 questions gauging the impact of nail psoriasis on daily activities. Each response is scored from 0 to 2, resulting in a total score between 0 and 20, where higher values indicate a more significant impact. The final scores are converted to percentages, reflecting the proportion of questions answered by the patient. The obtained score correlates proportionally with the level of functional difficulty experienced, with 0% indicating no impairment and 100% indicating the worst possible impairment.
Baseline, 24 weeks (end of study)
Number of Participants With at Least One Adverse Event
Time Frame: 24 weeks (end of study)
Adverse events will only include those that are determined to be related to the study drug.
24 weeks (end of study)
