NCT01235728

Brief Summary

This is a within-participant comparison study to investigate the efficacy of a 28-day regimen of MK-0873 2% cream twice a day (b.i.d.) compared to MK-0873 vehicle (matching placebo) b.i.d. as well as to a positive control comparator calcitriol 0.0003% (3 µg/g) in participants with plaque psoriasis. In order to be enrolled in the study, patients need to have at least two pairs (lesions AB and CD) of approximately similar plaque lesions in severity and size of surface area involved and located in approximately symmetric regions such as the trunk or limbs of the body. Participants will be randomly assigned to apply either MK-0873 or MK-0873 vehicle to plaque A or B and will be randomly assigned to apply MK-0873 or calcitriol to plaque C or D. It is hypothesized that MK-0873 cream formulation administered to participants with psoriasis by the topical route will result in a statistically greater percent target lesion severity (TLS) reduction in plaque lesion than will MK-0873 Vehicle on Day 29.

Outcome Measures

Primary Outcomes (1)

  • Least Squares Mean Percent Change From Baseline (Predose Day 1) of Target Lesion Severity (TLS) Score for Lesions Treated With MK-0873 and Lesions Treated With MK-0873 Vehicle

    Each lesion was evaluated for 3 components: erythema, induration, and scaling. Each component was given a score using the following scale: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked, with increasing score reflecting increased lesion severity. The TLS score (range 0 to 12) is calculated as the sum of the 3 components.

    Baseline and Day 29

Secondary Outcomes (2)

  • Least Squares Mean Percent Change From Baseline (Predose Day 1) of TLS Score for Lesions Treated With MK-0873 and Lesions Treated With Calcitriol

    Baseline and Day 29

  • Mean Maximum Plasma Concentrations at Trough of Day 8, 15, 22, and 29 Following Topical Administration of MK-0873 to Psoriatic Patients

    Day 8, 15, 22, 29
