Primary Outcome Measures
NameTimeMethod
Percentage of Participants With ITCH4 at Week 12Baseline; Week 12

ITCH4 response was defined as a ≥4-point improvement from Baseline in by-visit Itch Numeric Rating Scale (NRS) score. The Itch NRS is a daily participant-reported measure (24-hour recall) of the worst level of itch intensity. Participants rated itch severity of their lichen sclerosus by selecting a number from 0 (no itch) to 10 (worst imaginable itch) that best described the worst level of itch they experienced in the past 24 hours.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in the Clinical Lichen Sclerosus Score (CLISSCO) at Week 12Baseline; Week 12

The CLISSCO is a validated tool to assess disease severity in vulvar lichen sclerosus. The Clinical Lichen Sclerosus Score consists of 12 items divided into 3 sections: symptoms (3 items; likely reversible \[i.e., itch, pain, dysuria\]); signs (3 items; possibly reversible \[i.e., whitening, petechiae/ecchymosis, fissures\]); and architectural changes (6 items; irreversible \[i.e., skin fusion, perianal involvement, etc.\]). All symptoms, signs, and architectural changes were rated on a 4-point Likert scale: 0 (absent), 1 (mild), 2 (moderate), and 3 (severe). The investigator documented the score of each of the 12 items; the CLISSCO was calculated by summing the score of each question, with a maximum score of 36 and a minimum score of 0. The higher the score, the more severe the disease. Additionally, the total score for each of the 3 sections (symptoms, signs, and architectural changes) was summarized by summing the scores of the questions in each section.

Change From Baseline in the Skin Pain NRS Score at Week 12Baseline; Week 12

Participants were instructed to complete and record the Skin Pain NRS in a diary each evening beginning on the day of screening through Week 12 or treatment discontinuation. Participants rated their pain, which included all types of pain (e.g., burning, tearing, pulling, stabbing, etc.) severity of lichen sclerosus by selecting a number from 0 (no pain) to 10 (worst imaginable pain) that best described the worst level of pain they experienced in the past 24 hours.

Time to Achieve ITCH4up to 99.0 days

ITCH4 response was defined as a ≥4-point improvement from Baseline in by-visit Itch Numeric Rating Scale (NRS) score. The Itch NRS is a daily participant-reported measure (24-hour recall) of the worst level of itch intensity. Participants rated itch severity of their lichen sclerosus by selecting a number from 0 (no itch) to 10 (worst imaginable itch) that best described the worst level of itch they experienced in the past 24 hours.

Number of Participants With Any Treatment-emergent Adverse Event (TEAE) During the Double-blind, Vehicle-controlled Periodfrom Baseline to Week 12 plus 30 days

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE could therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drug. A TEAE was defined as an AE either reported for the first time or the worsening of a pre-existing event after the first application of study drug.

Number of Participants With Any ≥Grade 3 TEAE During the Double-blind, Vehicle-controlled Periodfrom Baseline to Week 12 plus 30 days

A TEAE was defined as an AE either reported for the first time or the worsening of a pre-existing event after the first application of study drug. The severity of AEs was assessed using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (v5.0) Grades 1 through 5. The investigator made an assessment of intensity for each AE and SAE reported during the study and assigned it to 1 of the following categories: Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated. Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age-appropriate activities of daily living. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living. Grade 4: life-threatening consequences; urgent treatment indicated. Grade 5: fatal.

Number of Participants With Any TEAE During the Open-label Extension Periodfrom Week 12 to Week 24 plus 30 days

An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE could therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drug. A TEAE was defined as an AE either reported for the first time or the worsening of a pre-existing event after the first application of study drug.

Number of Participants With Any ≥Grade 3 TEAE During the Open-label Extension Periodfrom Week 12 to Week 24 plus 30 days

A TEAE was defined as an AE either reported for the first time or the worsening of a pre-existing event after the first application of study drug. The severity of AEs was assessed using the CTCAE v5.0 Grades 1 through 5. The investigator made an assessment of intensity for each AE and SAE reported during the study and assigned it to 1 of the following categories: Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated. Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age-appropriate activities of daily living. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living. Grade 4: life-threatening consequences; urgent treatment indicated. Grade 5: fatal.

Number of Participants With Any Clinically Meaningful Changes Over Time in Clinical Laboratory Test Results During the Double-blind, Vehicle-controlled Periodfrom Baseline to Week 12 plus 30 days

The investigator determined if a clinical laboratory test value was clinically meaningful.

Number of Participants With Any Clinically Meaningful Changes Over Time in Vital Sign Values During the Double-blind, Vehicle-controlled Periodfrom Baseline to Week 12 plus 30 days

The investigator determined if a clinical laboratory test value was clinically meaningful.

Number of Participants With Any Clinically Meaningful Changes Over Time in Clinical Laboratory Test Results During the Open-label Extension Periodfrom Week 12 to Week 24 plus 30 days
