Efficacy and Safety Study of Desloratadine (MK-4117) in Japanese Participants With Eczema/Dermatitis and Dermal Pruritus (MK-4117-202)

A Phase III, Multicenter, Open-Label Long-Term Trial to Study the Efficacy and Safety of MK-4117 in Japanese Subjects With Eczema/Dermatitis and Dermal Pruritus.

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
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.	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)
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)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Pruritus/Itch Score (Sum of Daytime and Nighttime Scores) Assessed by the Investigator at Week 2	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.	Baseline Visit and Week 2 Visit
Percentage of Participants Who Experienced at Least One Adverse Event (AE)	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.	Up to 14 weeks (Up to 2 weeks after last dose dose of study drug)
Percentage of Participants Who Discontinued Study Drug Due to an AE	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.	Up to 12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	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.	Baseline Visit and Day 3 Visit, Week 1 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit
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	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.	Baseline Visit and Day 3 Visit, Week 1 Visit, Week 2 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit
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	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.	Baseline Visit and Day 3 Visit, Week 1 Visit, Week 2 Visit, Week 4 Visit, Week 6 Visit, Week 8 Visit, Week 12 Visit
