Trial Outcomes & Findings for Efficacy and Safety Study of Desloratadine (MK-4117) in Japanese Participants With Eczema/Dermatitis and Dermal Pruritus (MK-4117-202) (NCT NCT01916980)

NCT ID: NCT01916980

Last Updated: 2024-06-18

Results Overview

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.

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 anti-pruritic efficacy and there is no safety concern.
Desloratadine: Dermal Pruritus
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.

PRIMARY outcome

Timeframe: Baseline Visit and Week 2 Visit

Population: The Full Analysis Set (FAS) population consisted of all participants who received at least one dose of study drug and had a Baseline or at least one post-Baseline observation for Investigator-assessed pruritus/itch score.

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.

PRIMARY outcome

Timeframe: Up to 14 weeks (Up to 2 weeks after last dose dose of study drug)

Population: The All-Participants-as-Treated (APaT) population consisted of all participants who received at least one dose of study drug.

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.

Population: The FAS population consisted of all participants who received at least one dose of study drug and had a Baseline or at least one post-Baseline observation for Investigator-assessed Global Improvement.

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.

Population: The FAS population consisted of all participants who received at least one dose of study drug and had a Baseline or at least one post-Baseline observation for participant-assessed pruritus/itch VAS score.

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.
