Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Who Experienced Grade 3 Local Skin Reactions | Baseline up to Week 52 | Local skin reactions (itching, dryness, burning/stinging) graded at a level of 3 (severe) at any point in the study following the first application of study drug were assessed. Severe Itching (as reported by the participant within the last 24 hours) referred to the intense itching that may interrupt daily activities and/or sleep. Severe dryness (as assessed by the investigator) referred to as marked roughness of the skin. Severe burning/stinging (as reported by the participant within the last 24 hours) referred to as hot burning sensation that causes definite discomfort and may interrupt daily activities and/or sleep. A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module. |

Outcome results
Percentage of Participants Who Experienced Grade 3 Local Skin Reactions
Local skin reactions (itching, dryness, burning/stinging) graded at a level of 3 (severe) at any point in the study following the first application of study drug were assessed. Severe Itching (as reported by the participant within the last 24 hours) referred to the intense itching that may interrupt daily activities and/or sleep. Severe dryness (as assessed by the investigator) referred to as marked roughness of the skin. Severe burning/stinging (as reported by the participant within the last 24 hours) referred to as hot burning sensation that causes definite discomfort and may interrupt daily activities and/or sleep. A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.
Time frame: Baseline up to Week 52
Population: Safety population included all participants who received at least one confirmed dose of study drug and had at least one post-baseline safety assessment.
