About this study
Official title: A Phase 3, Randomized, Double-Blind, Vehicle-Controlled Study to Evaluate the Efficacy and Safety of Maintenance Treatment and Flare Reduction With Crisaborole Ointment, 2%, Once Daily Over 52 Weeks in Pediatric and Adult Participants (Ages 3 Months and Older) With Mild-to-Moderate Atopic Dermatitis, Who Responded to Twice Daily Crisaborole Ointment, 2%, Treatment
This study will evaluate crisaborole therapy once daily (QD) as a long-term topical maintenance therapy for the reduction of flare in responders to crisaborole twice daily (BID) treatment.
Read the detailed description
Approximately 700 participants will be enrolled in an run-in period to receive crisaborole, BID for up to a maximum of 8 weeks to identify crisaborole responders. A responder is defined as a participant who achieves both ISGA and EASI50 success. ISGA success is defined as achieving a score of 0 or 1 with at least 2 grade improvement from baseline; and the EASI50 success is defined as at least 50% improvement from baseline. Non responders at the end of the 8-week run-in period will be discontinued from the study.
Approximately 250 responders will be randomized (1:1 ratio) to enter the double-blind maintenance treatment period to receive crisaborole or vehicle QD for 52 weeks, with follow-up assessments every 4 weeks. If a flare occurs and if the participant meets the criteria for having a flare (ISGA ≥2), the participant will switch to enter a flare treatment period to receive open-label crisaborole BID for up to 12 weeks with follow-up assessments every 4 weeks. If the flare has resolved (ISGA ≤1) the participant will resume maintenance treatment and respective visit schedule. If a flare does not resolve after 3 consecutive treatment courses the participant will discontinue the study. A flare treatment period may comprise up to 3 consecutive treatment courses with crisaborole BID (each course is 4 weeks).
An end of study (EOS) safety follow-up is required 4 weeks after the last study treatment of any treatment period.

What is being measured
The primary outcome is the main question the study is designed to answer.
Duration of Flare-Free Maintenance Until Onset of First-Flare During the Double Blind (DB) Period
The duration of flare-free maintenance was the time from randomization to the last Investigator's Static Global Assessment (ISGA) and was right censored, if an intercurrent event (eg, death, dropout, loss to follow up, or end of study) occurred before the first flare. When a flare occurred first, the duration of flare free maintenance was the time from randomization to the first flare and was not censored. Duration of flare free maintenance was estimated using the Kaplan-Meier method.
Measured: From randomization to first flare or last ISGA assessment (up to 52 weeks)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
An adverse event (AE) was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a TEAE if the event started on or after the treatment period start date and before end of study (at least 28 days after last dose of study intervention).
Measured: Crisaborole 2% BID: From start of study intervention in OL period up to 8 weeks ; Vehicle QD and crisaborole 2% QD: From start of study intervention in DB period up to 28 days after last dose of study intervention (maximum of 56 weeks)
Secondary outcomes (100)
Number of Flare-Free Days During the DB Period
Flare - free days was the sum of the duration of flare-free maintenance during the DB maintenance period for each participant.
Measured: Up to maximum of 52 weeks
Number of Flares During the DB Period
Flare was defined as an ISGA score of >=2. The ISGA is a 5-point scale (range 0 to 4), reflecting a global assessment of AD severity based on erythema, induration/papulation, and oozing/crusting. ISGA score of 2: mild (faint pink erythema with mild induration/papulation and no oozing/crusting) 3: moderate (pink-red erythema with moderate induration/papulation with or without oozing/crusting) and 4: severe (deep or bright red erythema with severe induration/papulation and with oozing/crusting).
Measured: Up to maximum of 52 weeks
Secondary: Duration of Pruritus Response Maintenance Until Onset of First Flare During the DB Period: Participants Aged >=12 Years With Baseline Peak Pruritus Numerical Rating Scale (PP NRS) >=3, >=4 and >=3, >=4 Points Reduction in PP NRS
Duration of pruritus response maintenance=time from randomization to loss of pruritus response or first flare onset(ISGA>=2) during 52-week DB period evaluated among pruritus responders at randomization. Responders=participants with success in ISGA and EASI50 criteria. Pruritus response maintenance=maintenance of >=50% improvement in pruritus from baseline obtained at randomization. If event (e.g., death, first flare[ISGA >=2], lost to follow up or end of study) occurred before loss of pruritus response for first flare-free period, duration of pruritus response maintenance was time from randomization to last assessment and was censored. Here,pruritus response maintenance duration was presented for participants aged >=12 years with OL baseline PP NRS >=3, >=4 and >=3, >=4 points reduction from OL baseline to randomization in PP NRS. PP NRS: Participants were asked to rate their itch at worst moment during previous 24 hours on a scale of 0 to 10; 0=no itch and 10=worst itch imaginable".
Measured: From randomization up to loss of pruritus response or onset of first flare or the last assessment (maximum of 52 weeks)
Secondary: Duration of Pruritus Response Maintenance Until Onset of First Flare During the DB Period: Participants Aged 6 to <12 Years With Baseline Patient Reported Itch Severity (PRIS) >=2 and >=2 Points Reduction in PRIS
Duration of pruritus response maintenance=time from randomization to loss of pruritus response or first flare onset (ISGA>=2) during 52-week DB period. Evaluated among pruritus responders at randomization. Responders were defined as participants with success in ISGA and EASI50 criteria. Pruritus response maintenance=maintenance of >=50% improvement in pruritus from baseline that was obtained at randomization. If an event (e.g., death, first flare [ISGA >=2], lost to follow up, or end of study) occurred before loss of pruritus response for first flare-free period, duration of maintenance of pruritus response was time from randomization to last assessment and was censored. Here, pruritus response maintenance duration was presented for participants aged 6 to <12 years with baseline PRIS >=2 and >=2 points reduction from baseline to randomization in PRIS. PRIS: a 5-point scale (range: 0=no itch to 4=worst itch imaginable) and was completed by participants.
Measured: From randomization up to loss of pruritus response or onset of first flare or the last assessment (maximum of 52 weeks)
Duration of Pruritus Response Maintenance Until Onset of First Flare During the DB Period: Observer Reported Itch Severity Scale (ORIS) in Participants Aged 3 to <6 Months
Duration of pruritus response maintenance=time from randomization to loss of pruritus response or first flare onset(ISGA>=2)during52-weekDB period. Evaluated among pruritus responders (success in ISGA, EASI 50) at randomization. Pruritus response maintenance=maintenance of >=50% improvement in pruritus from baseline obtained at randomization. If event(e.g., death, first flare[ISGA >=2], lost to follow up, or end of study) occurred before loss of pruritus response for first flare-free period, duration of maintenance of pruritus response was time from randomization to last assessment and was censored. Here, pruritus response maintenance duration was presented for participants aged 3 to <6 months with OL baseline ORIS>=3 or >=4 and >=3 or >=4 points reduction from OL baseline to randomization in ORIS. Caregivers were asked to rate observation of their child's itch(scratching, rubbing) at worst moment during previous 24 hours on a scale of 0 to 10;0=no itch,10=worst itch imaginable.
Measured: From randomization up to loss of pruritus response or onset of first flare or the last assessment (maximum of 52 weeks)

EASI assessed severity of AD, based on severity of lesion clinical signs (erythema [E], induration/papulation [I], excoriation [Ex], lichenification [L]) and % body surface area (BSA) affected. Each of clinical signs scored separately for each of 4 body regions (head and neck [h], upper limbs [u], trunk [t] [including axillae and groin], lower limbs [l] [including buttocks]) on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score (A) according to %BSA with AD: 0 (0%), 1(>0 to <10%), 2(10 to <30%), 3(30 to <50%), 4(50 to <70%), 5(70 to <90%), 6 (90 to 100%). Total EASI score =0.1*Ah*(Eh + Ih + Exh + Lh) + 0.2*Au*(Eu + Iu + ExU + Lu) + 0.3*At*(Et +It + Ext + Lt) + 0.4*Al*(El + Il + Exl + Ll). Total EASI score ranged from 0.0 to 72.0, higher score = greater severity of AD. EASI response maintenance = score that does not lose more than 50% of achieved reduction from Day1/Baseline run-in EASI score.
Measured: From randomization to loss of EASI response or onset of first flare or the last EASI assessment (up to maximum of 52 weeks)
Duration of Maintenance of Dermatology Life Quality Index (DLQI) Response Until Onset of First Flare During the DB Period
Duration of DLQI maintenance=time from randomization to loss of DLQI response during 52-week DB period for responders at randomization. If event(e.g., death, first flare[ISGA >=2], lost to follow up or end of study) occurred before loss of DLQI response, duration of maintenance of DLQI response=time from randomization to last assessment and censored. Responders=participants with success in ISGA,EASI50 criteria. DLQI response maintenance=response that does not lose more than minimal clinical important difference. DLQI =10-item questionnaire, measured impact of skin disease in participants aged >=16 years. Children's DLQI (CDLQI): participants aged 4 to15 years. Each question in DLQI and CDLQI evaluated on 4-point scale (range 0=not at all to 3=very much). Scores from10 items were added for DLQI/CDLQI total score, range:0 (not at all) to 30 (very much). Higher scores=more impact on quality of life of participants/children.
Measured: From randomization to loss of DLQI response or onset of first flare or the last assessment up to first flare (up to maximum of 52 weeks)
Duration of Maintenance of Patient Oriented Eczema Measure (POEM) Response Until Onset of First Flare During the DB Period
POEM was a 7-item participant reported outcome measure used to assess the impact of AD (dryness, itching, flaking, cracking, sleep loss, bleeding and weeping) over the past week. Each item was scored as: no days=0, 1-2 days=1, 3-4 days=2, 5-6 days=3 and every day=4. The total score ranged from 0 to 28, where higher score indicated greater severity. POEM response maintenance was defined as the response that does not lose more than minimal clinical important difference. Duration of POEM maintenance was time from randomization to loss of POEM response during 52-week DB period for responders at randomization. Responders were defined as participants with success in ISGA and EASI50 criteria. If an event (e.g., death, first flare [ISGA >=2], lost to follow up, or end of study) occurred before loss of POEM response, duration of maintenance of POEM response was time from randomization to last assessment and was censored. Proxy POEM was used for participants aged 3 months to <12 years.
Measured: From randomization to loss POEM response or onset of first flare or the last assessment up to the first flare (up to maximum of 52 weeks)
Investigator's Static Global Assessment (ISGA) Score for the First Flare Period

EQ-5D-5L: standardized participant completed questionnaire consisted of 2 components: a health state profile/a single utility index value and an optional VAS. EQ-5D health state profile/a single utility index value had 5 dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression. Each dimension has 5 levels: 1= no problems, 2= slight problems, 3= moderate problems, 4= severe problems and 5= extreme problems. Responses to 5 dimensions comprised a health state/a single utility index value. E.g. if a participant responded "no problems" for each 5 dimensions, then health state was coded as "11111" with a predefined index value to it. Every health state (coded as combination of responses on each of 5 dimensions) had a unique predefined utility index value assigned to it, by EuroQol. US value sets (with all possible health states) was used for adults in the study and total scores ranged from 1 to -0.109. Higher (positive) scores = better health state.

EuroQoL EQ-5D Y Index Scores in Participants Between 8-17 Years of Age: First Flare Period
EQ-5D-Y: child-friendly version of EQ-5D questionnaire related to health status. Health state profile assessed health in 5 dimensions (mobility; looking after myself; doing usual activities; having pain or discomfort; feeling worried, sad or unhappy) used to obtain an index score, each of which had three levels of response (no problems/no pain/not worried, some problems/some pain/a bit worried, a lot of problems/a lot of pain/very worried). Participants indicated their health state by choosing the appropriate level from each dimension. The 5 digit health states thus obtained for each dimension were then converted into a single median index value. A health state index score was calculated from individual health profiles using a USA scoring algorithm. Health state index scores generally ranged from -0.109 to 1, where,-0.109= the worst health status, 1= full health. Higher the score the better the health status. A positive change from baseline indicated improvement in health status.

Total Anxiety and Depression Scores Measured Using Hospital Anxiety and Depression Scale (HADS): OL Run-in Period
HADS was a validated 14-item questionnaire to assess states of anxiety and depression over the past week. HADS consisted of 2 subscales: HADS-anxiety (HADS-A) and HADS-depression (HADS-D), each of which comprised of 7 items. Each item was rated on a 4-point scale, with scores ranging from 0 to 3, where higher scores indicated more anxiety/depression symptoms. HADS-A assessed state of generalized anxiety. HADS-A total score = sum of all 7 items with score ranging from 0 (no presence of anxiety) to 21 (severe feeling of anxiety); higher score indicated greater severity of anxiety. HADS-D assessed the state of lost interest and diminished pleasure response. HADS-D total score = sum of all 7 items with score ranging from 0 (no presence of depression) to 21 (severe feeling of depression); higher score indicated greater severity of depression symptoms.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will evaluate crisaborole therapy once daily (QD) as a long-term topical maintenance therapy for the reduction of flare in responders to crisaborole twice daily (BID) treatment.
Detailed description
Approximately 700 participants will be enrolled in an run-in period to receive crisaborole, BID for up to a maximum of 8 weeks to identify crisaborole responders. A responder is defined as a participant who achieves both ISGA and EASI50 success. ISGA success is defined as achieving a score of 0 or 1 with at least 2 grade improvement from baseline; and the EASI50 success is defined as at least 50% improvement from baseline. Non responders at the end of the 8-week run-in period will be discontinued from the study.
Approximately 250 responders will be randomized (1:1 ratio) to enter the double-blind maintenance treatment period to receive crisaborole or vehicle QD for 52 weeks, with follow-up assessments every 4 weeks. If a flare occurs and if the participant meets the criteria for having a flare (ISGA ≥2), the participant will switch to enter a flare treatment period to receive open-label crisaborole BID for up to 12 weeks with follow-up assessments every 4 weeks. If the flare has resolved (ISGA ≤1) the participant will resume maintenance treatment and respective visit schedule. If a flare does not resolve after 3 consecutive treatment courses the participant will discontinue the study. A flare treatment period may comprise up to 3 consecutive treatment courses with crisaborole BID (each course is 4 weeks).
An end of study (EOS) safety follow-up is required 4 weeks after the last study treatment of any treatment period.

Primary outcome
Duration of Flare-Free Maintenance Until Onset of First-Flare During the Double Blind (DB) Period
Time frame: From randomization to first flare or last ISGA assessment (up to 52 weeks)
The duration of flare-free maintenance was the time from randomization to the last Investigator's Static Global Assessment (ISGA) and was right censored, if an intercurrent event (eg, death, dropout, loss to follow up, or end of study) occurred before the first flare. When a flare occurred first, the duration of flare free maintenance was the time from randomization to the first flare and was not censored. Duration of flare free maintenance was estimated using the Kaplan-Meier method.
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Time frame: Crisaborole 2% BID: From start of study intervention in OL period up to 8 weeks ; Vehicle QD and crisaborole 2% QD: From start of study intervention in DB period up to 28 days after last dose of study intervention (maximum of 56 weeks)
An adverse event (AE) was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a TEAE if the event started on or after the treatment period start date and before end of study (at least 28 days after last dose of study intervention).
