May 2010   (Final data collection date for primary outcome measure)
  • Change in Pruritis Visual Analog Scale (VAS) [ Time Frame: Baseline through Study Day 36 (Visit 7) ]
    Patient reported outcome of pruritis measurement (0-100 mm/min-max)on a change in visual analog scale
  • Safety and Tolerability of TS-022 Topical Lotion as Measured by Participants Who Demonstrated Adverse Events [ Time Frame: Baseline through Study Day 36 (Visit 7) ]
    Safety assessment of all subjects who received investigational product. Outcome measure is number of subjects with an adverse event. Measures of adverse events in participants included vital signs, laboratory findings, physical exams, electrocardiograms
  • Investigator's Global Assessment (IGA) Based on a Dermatologist's Evalution of the Change in Subject's Score of Target Treatment Areas [ Time Frame: baseline through Study Day 36 (Visit 7) ]
    investigator assessment of disease status rated on 0-5 scale (0 = clear to 5 = very severe) based on a change in score from baseline to Study Day 36 (Visit 7)
  • Five Point Pruritus Scale for Self-Assessment of Target Treatment Area Based on a Change in Score [ Time Frame: Baseline, which is Day -7 (Visit 2), through Day 36 (Visit 7) ]
    self-assessment using a five point scale of pruritus state based on a change in scale from none (0) to very severe (4), interfering with daily or sleep activities. Subjects will complete the Five-Point Pruritus Scale once at Screening (Visit 1), then twice daily beginning at baseline, which occurs on the morning of Study Day -7 (Visit 2), through Study Day 36 (Visit 7)
  • Eczema Area and Severity Index (EASI) Based on a Change in Score of Eruption in Proportionate Body Surface Areas [ Time Frame: baseline through Study Day 36 (Visit 7) ]
    The head and neck [10%], trunk [30%], upper extremities [20%] and lower extremities [40%] were assessed separately for erythema (E), infiltration/papulation (I), excoriation (Ex) and lichenification (L) represented by a numeric coded value of (0, No eruption) to (6, 90% - 100% eruption). One score given to each part of the body on a scale from 1-6 based on the four attributes (E, I, Ex, L) and then a proportional average is taken to get a total score of 1-6.
  • Skindex-29 Questionnaire to Measure the Subject's Overall Quality of Life Based on Activities of Daily Living That Affect Change in Emotion (10 to 50 Points), Symptoms (7 to 35 Points) and Functioning (12 to 60 Points) to Skin Over One Week Period. [ Time Frame: Study Day -7 through Study Day 22 ]
    Assessment of subject's activities of daily living using the SKINDEX-29 questionnaire to measure the subject's overall quality of life based on a change in scale from baseline. The SKINDEX scoring scale has a range of 29-145. The smaller the number the better the patient feels. The results are the difference of the SKINDEX scoring scale at treatment discharge (day 22) minus baseline (day-7). Hence the results should be negative, as the patient's emotion, symptoms and functioning of the skin should feel better at treatment discharge as opposed to baseline.
  • Number of Participants Who Had Measurable Pruritis Based on a Visual Horizontal Analog Scale [ Time Frame: Baseline through Study Day 36 (Visit 7) ]
    Pruritis Visual Analog Scale (VAS) based on patient reported outcome of pruritis measurement on a VAS indicating the amount of pruritus (itchiness) experienced from the time of last dose application through the time just before current dose application. Change in pruritus is assessed twice daily beginning at baseline, Study Day -7 (Visit 2), through Study Day 36 (Visit 7). Subjects determine measurable pruritis using a visual horizontal analog scale ranging from "No Itch", even the slightest itch or "Slight Itch", to "Worst Itch Imaginable" to denote the increase in severity of itching.
  • Visual Analog Scale (VAS) [ Time Frame: Twice Daily ]
  • Evaluate safety and tolerability of TS-022 topical lotion for 28 days; assessing adverse events, vital signs, laboratory findings, physical exams, electrocardiograms [ Time Frame: Daily ]
  • Investigator's Global Assessment (IGA) [ Time Frame: Week 1, Week 2, Week 3, Week 4 and Week 6 ]
  • Five Point Pruritus Scale [ Time Frame: Twice Daily ]
  • Eczema Area and Severity Index (EASI) [ Time Frame: Week 1, Week 2, Week 3, Week 4 and Week 6 ]
  • Skindex-29 Quality of Life Determination [ Time Frame: Week 4 and Week 6 ]

Study of TS-022 in Adult Patients With Atopic Dermatitis With Pruritus (POC)
A Multicenter, Randomized, Double-Blind, Vehicle-Controlled Study of the Efficacy, Safety and Tolerability of TS-022 in Adult Patients With a Diagnosis of Atopic Dermatitis (AD) With Moderate to Very Severe Pruritus
The purpose and (primary) objectives of this study are to evaluate the efficacy, safety, and tolerability of TS-022 in adults with atopic dermatitis who have moderate to very severe pruritus (itching), following a 28-day regimen of twice-daily topical application.
