Outcomes
Primary Outcome Measures
Change From Baseline in Ichthyosis Area Severity Index (IASI) Total Score at Week 16
IASI quantified the severity of participants ichthyosis based on severity of erythema/scaling & percentage of body surface area (BSA) affected. Degree of erythema & scaling scored from 0 (none) to 4 (very severe) for each of 4 body regions (BR) [A1: head & neck (H&N), A2: upper limbs (UL), A3: trunk (T), A4: lower limbs (LL)]. Percentage of BSA involved for each BR (B1: % in H&N, B2: % in UL, B3: % in T, B4: % in LL). Percentage involvement was assigned numerical value(0= 0, 1%-9%= 1, 10%-29%= 2, 30%-49%= 3, 50%-69%= 4, 70%-89%= 5, 90%-100%= 6).Total extent was determined using multiplier considering % of total BSA by each BR (C1= 0.1 for H&N; C2= 0.2 for UL; C3= 0.3 for T; C4= 0.4 for LL).
IASI-Erythema (E)= A1E x B1 x C1 + A2E x B2 x C2 + A3E x B3 x C3 + A4E x B4 x C4 (score 0 to 24) IASI-Scaling (S)= A1S x B1 X C1 + A2S x B2 x C2 + A3S x B3 x C3 + A4S x B4 x C4 (score 0 to 24) IASI total score= IASI-E + IASI-S score ranged from 0 - 48, higher score indicated worse disease state.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)
An AE was any untoward medical occurrence in a participant temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An AE could therefore be any unfavorable and unintended sign (including abnormal laboratory finding), symptom, or disease temporally associated with use of study treatment that did not necessarily have a causal relationship with this treatment. An AE was considered "serious" if there was any of the following outcomes: death, life-threatening adverse event, Inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, congenital anomaly/birth defect, other important medical events. An adverse event was considered TE if the date of onset was during or after first dose of study treatment, or if the AE present at baseline worsened in either intensity or frequency after first dose of study treatment.

Brief Summary
Efficacy and Safety of imsidolimab in Participants with Ichthyosis
Detailed Description
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, and tolerability of imsidolimab compared with placebo in adolescent and adult participants with ichthyosis. This study will also characterize the pharmacokinetic (PK) profile of imsidolimab and explore the immune response to imsidolimab in participants with ichthyosis.
