  Purpose

This is an efficacy and safety study of up to 12 weeks of desloratadine in Japanese participants with eczema/dermatitis and dermal pruritus. The primary hypothesis of this study is that the sum of the daytime and nighttime pruritus/itch scores for both the eczema/dermatitis group and the dermal pruritus group will be significantly improved at Week 2 compared to Baseline.


Condition Intervention Phase
Eczema
Dermatitis
Dermal Pruritus
Drug: Desloratadine 5 mg
Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Primary Outcome Measures:
  • Change From Baseline in Pruritus/Itch Score (Sum of Daytime and Nighttime Scores) Assessed by the Investigator at Week 2 [ Time Frame: Baseline Visit and Week 2 Visit ] [ Designated as safety issue: No ]
    The Investigator assessed the severity of participant pruritus/itch during the daytime (0=Virtually no itching to 4=Cannot relax because of constant itching) and nighttime (0=Virtually no itching to 4=Cannot sleep because of itching). The sum of the daytime and nighttime pruritus/itch scores could range from 0 to 8, with a higher sum score indicating greater severity. The change from Baseline in the sum of the daytime and nighttime pruritus/itch scores at Week 2 clinic visit was calculated.

  • Percentage of Participants Who Experienced at Least One Adverse Event (AE) [ Time Frame: Up to 14 weeks (Up to 2 weeks after last dose dose of study drug) ] [ Designated as safety issue: Yes ]
    An AE is any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the study drug is also an AE.

  • Percentage of Participants Who Discontinued Study Drug Due to an AE [ Time Frame: Up to 12 weeks ] [ Designated as safety issue: Yes ]
    An AE is any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug or protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the study drug is also an AE.


Secondary Outcome Measures:
  • Change From Baseline in Pruritus/Itch Score (Sum of Daytime and Nighttime Scores) Assessed by the Investigator at Day 3, Week 1, Week 4, Week 6, Week 8 and Week 12 [ Time Frame: Baseline Visit and Day 3 Visit, Week 1 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit ] [ Designated as safety issue: No ]
    The Investigator assessed the severity of participant pruritus/itch during the daytime (0=Virtually no itching to 4=Cannot relax because of constant itching) and nighttime (0=Virtually no itching to 4=Cannot sleep because of itching). The sum of the daytime and nighttime pruritus/itch scores could range from 0 to 8, with a higher sum score indicating greater severity. The changes from Baseline in the sum of the daytime and nighttime pruritus/itch scores at the Day 3, Week 1, Week 4, Week 6, Week 8 and Week 12 clinic visits were calculated.

  • Percentage of Participants With Moderate or Remarkable Improvement in the Global Improvement Rate of Pruritus/Itch Assessed by the Investigator at Day 3, Week 1, Week 2, Week 4, Week 6, Week 8 and Week 12 [ Time Frame: Baseline Visit and Day 3 Visit, Week 1 Visit, Week 2 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit ] [ Designated as safety issue: No ]
    The global improvement judgment criteria were used to assess overall improvement in pruritus/itch. The Investigator assessed the degree of severity of pruritus/itch based on 5 grades (1=Remarkably improved to 5=Aggravated) at Baseline and subsequent clinic visits. The percentages of participants who were remarkably improved (Grade 1=Pruritus/itch disappeared) or moderately improved (Grade 2=Pruritus/itch was greatly improved) at the Day 3, Week 1, Week 2, Week 4, Week 6, Week 8 and Week 12 clinic visits were calculated.

  • Change From Baseline in the Pruritus/Itch Visual Analog Scale (VAS) Score Recorded by Participants at Day 3, Week 1, Week 2, Week 4, Week 6, Week 8 and Week 12 [ Time Frame: Baseline Visit and Day 3 Visit, Week 1 Visit, Week 2 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit ] [ Designated as safety issue: No ]
    Participants assessed the degree of their pruritus using a 100-mm visual analog scale (VAS; 0mm=No itch, 100mm=Worst imaginable itch) at Baseline and subsequent clinic visits. Pruritus/itch VAS scores could range from 0 to 100, with a higher score indicating more severe pruritus/itching. The changes from Baseline in the VAS scores for pruritus/itch at the Day 3, Week 1, Week 2, Week 4, Week 6, Week 8 and Week 12 clinic visits were calculated.

Arms Assigned Interventions
Experimental: Desloratadine: Eczema/Dermatitis
Participants with eczema/dermatitis receive desloratadine 5 mg, taken as one 5-mg tablet, orally once daily in the evening for up to 12 weeks. After Week 4, the dose of desloratadine can be increased from 5 mg/day to 10 mg/day (two 5-mg tablets, orally once daily in the evening for up to 8 weeks), if criteria for dose up-titration are met, there is insufficient antipruritic efficacy and there is no safety concern.

Desloratadine 5 mg/day: one 5-mg tablet taken orally once daily in the evening for up to 12 weeks (Desloratadine 10 mg/day: two 5-mg tablets taken orally once daily in the evening for up to 8 weeks)
Experimental: Desloratadine: Dermal Puritus
Participants with dermal pruritus receive desloratadine 5 mg, taken as one 5-mg tablet, orally once daily in the evening for up to 12 weeks. After Week 4, the dose of desloratadine can be increased from 5 mg/day to 10 mg/day (two 5-mg tablets, orally once daily in the evening for up to 8 weeks), if criteria for dose up-titration are met, there is insufficient anti-pruritic efficacy and there is no safety concern.
Drug: Desloratadine 5 mg
Desloratadine 5 mg/day: one 5-mg tablet taken orally once daily in the evening for up to 12 weeks (Desloratadine 10 mg/day: two 5-mg tablets taken orally once daily in the evening for up to 8 weeks)
