Study Endpoints
Primary Endpoints
Change From Baseline in the Sum Score of Pruritus/Itch and Rash Assessed by Investigator at Week 2
Baseline Visit and Week 2 Visit

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 score used for pruritus/itch was the higher of the day or night scores (0=Asymptomatic to 4=Severe). The Investigator also assessed the severity of participant rash using the overall rash score (0=No rash to 3=Looks very bad). The sum of the pruritus/itch score (0-4) and rash score (0-3) could range from 0 to 7, with a higher sum score indicating greater severity. The change from Baseline in the sum of the pruritus/itch and overall rash scores at the Week 2 clinic visit was calculated.

Number of Participants Who Experienced at Least One Adverse Event (AE)
Up to 4 weeks (Up to 2 weeks after last 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.

Number of Participants Who Discontinued Study Drug Due to an AE
Up to 2 weeks

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.
