Primary Outcome Measures
NameTimeMethod
Number of Participants With Adverse Events (AE)From Baseline (Day 1) until Week 12

An AE was defined as "any untoward medical occurrence in a clinical trial participant (regardless of the administration of the study drug and its causal relationship to it). An AE could therefore, be any unfavorable and unintended medical occurrence during the participant's participation in the trial, including deterioration of a pre-existing medical condition, an abnormal clinically significant finding in a laboratory assessment, or an abnormal clinically significant finding in the physical examination or vital sign.

Change From Baseline in Systolic and Diastolic Blood PressureBaseline (Day 1), Week 12

Change from baseline in systolic and diastolic blood pressure was evaluated. Change from baseline was calculated by subtracting post-dose value from baseline value.

Change From Baseline in Heart RateBaseline (Day 1), Week 12

Change from baseline in heart rate was evaluated. Change from baseline was calculated by subtracting post-dose value from baseline value.

Change From Baseline in Respiratory RateBaseline (Day 1), Week 12

Change from baseline in respiratory rate was assessed. Change from baseline was calculated by subtracting post-dose value from baseline value.

Change From Baseline in Body TemperatureBaseline (Day 1), Week 12

Change from baseline in body temperature was assessed. Change from baseline was calculated by subtracting post-dose value from baseline value.

Change From Baseline in WeightBaseline (Day 1), Week 12

Change from baseline in weight was assessed. Change from baseline was calculated by subtracting post-dose value from baseline value.

Change From Baseline in HeightBaseline (Day 1), Week 12

Change from baseline in height was assessed. Change from baseline was calculated by subtracting post-dose value from baseline value.

Local Dermal Tolerability: Number of Participants With Dryness, Scaling and Erythema as Assessed by InvestigatorWeek 12

Local dermal tolerability was evaluated by investigator in terms of presence and absence of dryness, scaling and erythema symptoms and its severity in the areas of body where medication was applied. These symptoms were assessed by using a 4 - point scale of 0 - 3, where 0 = none (no dryness, scaling and erythema) and 3 = severe (marked roughness, heavy scale production and intense redness). The higher score indicated severe symptoms.

Local Dermal Tolerability: Number of Participants With Stinging/Burning Symptoms as Assessed by ParticipantsWeek 12

Local dermal tolerability was evaluated by participants in terms of presence and absence of prickling pain sensation immediately after (within 5 minutes of dosing) and its severity in the areas of body where medication was applied (face). Stinging/burning symptoms were graded on a 4-point scale of 0 - 3 where 0 = none (no stinging/burning), 1 = mild (slight warm, tingling/stinging sensation; not really bothersome), 2 = moderate (definite warm, tingling/stinging sensation that is somewhat bothersome), 3 = severe (hot, tingling/stinging sensation that has caused definite discomfort). The higher score indicated severe symptoms.
