What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cohort 1: Skin Irritation Index
Time Frame: Day 3 to 4
The skin irritation index is a common measure of skin irritation potential (safety criteria) of investigational product and derived using skin irritation scores. Individual skin irritation score ranges from 0-4, where 0 = no reaction, 0.5 = mild erythema, 1 = erythema, 2 = erythema with edema and papula, 3 = erythema with edema, papula and small water blister, 4 = large water blister, higher score indicates more skin irritation. For each investigational product, the skin irritation index was calculated as the sum of the maximum individual skin irritation scores divided by the number of evaluable participants and multiplied by 100, which ranged from 0 to 400; where, lower score indicated less skin irritation and higher score indicated more skin irritation.
Day 3 to 4
Cohort 2: Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)
Time Frame: Baseline up to Day 36
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 28 days after last dose of study drug (up to Day 36) that were absent before treatment or that worsened relative to pre-treatment state. AEs included both SAEs and non-serious AEs.
Baseline up to Day 36
Cohort 2: Number of Participants With Clinically Significant Vital Signs Abnormalities
Time Frame: Baseline up to end of treatment (Day 8)
Vital signs included pulse rate and blood pressure. Clinical significance of vital signs was determined at the investigator's discretion.

Baseline up to end of treatment (Day 8)
Cohort 2: Number of Participants With Clinically Significant Electrocardiogram (ECG) Abnormalities
Time Frame: Baseline up to end of treatment (Day 8)
Criteria for clinically significant ECG abnormalities included: QT interval >=500 milliseconds (msec); QT interval corrected using the Fridericia's formula (QTcF) >=450 msec to <480 msec, >=480 msec and >=500 msec; increase from baseline in QTcF interval >=30 msec to <60 msec and >=60 msec.
Baseline up to end of treatment (Day 8)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cohort 1: Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)
