Study Type: Interventional

Official Title: The Efficacy and Safety of Tacrolimus Ointment in Adult Patients With Moderate to Severe Atopic Dermatitis

Brief Summary: The purpose of this study is to evaluate the safety and efficacy of tacrolimus ointment in treating the signs and symptoms of moderate (medium level of seriousness) to severe (very serious, life threatening) atopic dermatitis (an intensely pruritic [itching], chronic [lasting a long time], inflammatory [pain and swelling], immunologically based skin disease with a genetic predisposition [latent susceptibility to disease at the genetic level]) in adult participants.

Detailed Summary: This is an open-label (all people know the identity of the intervention), prospective (study following participants forward in time), randomized (like the flip of a coin), multi-center study in adult participants with moderate to severe atopic dermatitis. Participants will be treated with 0.1 percent concentration of tacrolimus ointment which will be applied twice daily for 4 weeks or until 1 week after the affected areas defined for treatment at baseline are completely cleared, whichever is first. The study will consist of 6 visits: pre-study (optional), Baseline or Day 1, Weeks 1, 2, 3 and 4 (end-of-treatment). The ointment should be applied at least 2 hours before or at least 30 minutes after bathing, showering, shaving, use of sauna, or heavy exercise (i.e. causes sweating). On study visit days, the ointment should be applied at least 2 hours before the visit. Efficacy evaluation will be done at all subsequent study visits in participants receiving study drug for at least 3 consecutive days (minimum of 5 applications) while the participants who will receive at least 1 application of the study drug, will be evaluated for safety. Primary efficacy evaluation will be based on the Physician's Global Evaluation of Clinical Response (PhGECR). Participants' safety will be monitored throughout the study.

Current Primary Outcome: Physician's Global Evaluation of Clinical Response (PhGECR) [ Time Frame: Week 4 ]

PhGECR scale evaluates the change in the lesions of atopic dermatitis, which is defined as the lesions identified by Investigator for treatment at Baseline only, using scores ranging from, less than 0 to 100: wherein, less than 0=worse, 0-29=no appreciable improvement, 30-49=slight improvement, 50-74=moderate improvement, 75-89=marked improvement, 90-99=excellent improvement and 100=cleared.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Eczema Area and Severity Index (EASI) [ Time Frame: Week 1, 2, 3 and 4 ]
    A composite index of area involved and severity of the signs of atopic dermatitis in the 4 regions (head and neck, upper limbs, trunk, lower limbs) will be calculated using the physician's assessment of individual signs using a scale ranging from 0 to 3: 0=absent, 1=mild, 2=moderate, 3=severe; and the affected area assessment (the percentage of body surface area affected by atopic dermatitis) of the lesions defined in the baseline treatment area will be estimated by the physician on the basis of area score ranging from 0 to 6: 0=0 percent and 6=90 to 100 percent.
  • Participant's Assessment of Treatment Effects [ Time Frame: Week 1, 2, 3 and 4 ]
    Participants will make 2 assessments at each study visit (before and after treatment) based on all affected areas (ratio of 100 percent). The assessment rates include: much better, better, slightly better, same, slightly worse, worse. Much better and better is considered good.
  • Participant's Assessment of Itch [ Time Frame: Week 1, 2, 3 and 4 ]
    Participant's itch will be assessed using a Visual Analog Scale ranging from 0 to 100: 0-19=no or slight itch; 20-39=mild itch; 40-59=moderate itch; 60-79=severe itch; 80-100=worst itch.


Original Secondary Outcome: Same as current
