Dose Response and Safety Study of Topical Methotrexate for the Treatment of Fingernail Psoriasis
- Registration Number
- NCT00666354
- Lead Sponsor
- MediQuest Therapeutics
- Brief Summary
The purpose of this clinical study is to compare the efficacy and safety of three concentrations of topical methotrexate for the treatment of fingernail psoriasis.
- Detailed Description
The purpose of this clinical study is to compare, in a controlled fashion, the response to three concentrations of methotrexate in novel topical formulations in the treatment of subjects with psoriasis of the fingernails.

Group Intervention Description 2 Methotrexate - 1 Methotrexate - 3 Methotrexate -
- Primary Outcome Measures
Name Time Method Evaluate improvements in the appearance of the target fingernail, utilizing photography for imaging and independent photograph evaluators. Monthly
- Secondary Outcome Measures
Name Time Method Improvement in appearance of the control fingernail, improvement of the target fingernail using mNAPSI (a modification of the Nail Psoriasis Severity Index), and comparison of improvement of mNAPSI of the target and control fingernails. Monthly Information on the relative changes in nail psoriasis severity of the other affected fingernails will be collected. Monthly Comparison of nail growth of the target and control fingernails as determined from nail notch movement measured on nail photographs will be performed. Monthly Assess safety, i.e., the frequency and severity of adverse events associated with MQX-5902, MQX-5904 and MQX-5906 in the treatment of patients with fingernail psoriasis. Monthly
