Trial Outcomes & Findings for Study to Assess the Efficacy and Safety of Orismilast in Atopic Dermatitis (ADESOS) (NCT NCT05469464)

The study was conducted in Germany (9 sites), Poland (17 sites), Hungary (4 sites), and the United States (27 sites).

Number of participants analyzed includes the total number of participants evaluable in each treatment arm.

The EASI is a tool to measure the severity of clinical signs and the percentage of affected body surface area (BSA) in patients with atopic dermatitis (AD). The EASI is a composite scoring system to evaluate the degree of erythema, induration/papulation, excoriation, and lichenification (each scored separately) for each of 4 body regions, with adjustment for the percentage of BSA involved for each body region and for the proportion of the body region to the whole body. EASI scores range from 0 to 72, with higher scores reflecting greater disease severity. Erythema, induration/papulation, excoriation, and lichenification are scored on a scale of 0 (absent) to 3 (severe) for each body region: head and neck, upper limbs (including the external axillae and hands), trunk (including the internal axillae and groin), and lower limbs (including the buttocks and feet). The extent of affected skin in each body region is scored on a scale of 0 (no involvement) to 6 (90% to 100% involvement).

The IGA-AD is a measure used by physicians to determine a patient's overall severity of disease. The static version was used for measurement at a single point in time. The Investigator rated the severity of the patient's AD on a 5-point scale ranging from 0 (clear) to 4 (severe).

The severity of itch (pruritus) due to AD was assessed using a horizontal 11-point NRS. Patients were asked to assess their "worst itching due to AD over the past 24 hours" on an NRS anchored by the terms "no itching" (0) and "worst possible itching" (10).

The BSA assessment estimated the extent of disease or skin affected by AD and was expressed as a percentage of total BSA. BSA was determined by the Investigator or designee using the participant's hand (palm + fingers) = 1% BSA rule.

The DLQI is a 10-item validated questionnaire completed by the patient and used to assess the effect of skin disease on the patient's quality of life during the previous week. The 10 questions cover the following topics: symptoms; embarrassment; interference with shopping and home care, clothing choices, social and leisure activities, sports participation, work or study, close relationships, and sex; and treatment. Each question is scored from 0 to 3 ("not at all," "a little," "a lot," and "very much," respectively), giving a total score ranging from 0 to 30. A high score is indicative of a poor quality of life.

The POEM is a 7-item, validated questionnaire completed by the patient to assess disease symptoms. Patients were asked to respond to questions on frequency of sleep loss and skin dryness, itching, flaking, cracking, bleeding, and weeping over the past week. All answers carry equal weight, with a total possible score ranging from 0 to 28. A high score is indicative of a poor quality of life.

The PGIS scale is a single question asking the patient how he or she would rate his or her overall AD symptoms over the past 24 hours. The 5 categories of responses are (0) "no symptoms", (1) "very mild", (2) "mild", (3) "moderate", and (4) "severe."

The PGIC scale measures change in clinical status of AD. The PGIC is based on a 7-point scale, and the patient will rate the change from the start of treatment as 1 "very much improved," 2 "much improved," 3 "minimally improved," 4 "no change," 5 "minimally worse," 6 "much worse," and 7 "very much worse."

The sleep disturbance NRS is a scale used by the patients to report their degree of sleep loss related to AD. Patients were asked the following question in their local language: how would you rate your sleep last night? On a scale of 0 to 10, with 0 being "no sleep loss related to signs/symptoms of AD" and 10 being "I cannot sleep at all because of the signs/symptoms of AD". Higher scores indicate worse outcomes.

The skin pain NRS is a patient-administered, 11-point horizontal scale anchored at 0 and 10, with 0 representing "no pain" and 10 representing "worst pain imaginable." Overall severity of a participant's skin pain is indicated by selecting the number that best describes the worst level of skin pain in the past 24 hours.

An adverse event (AE) is any symptom, physical sign, syndrome, or disease that either emerges during the study or, if present at screening, worsens during the study, regardless of the suspected cause of the event.

The HADS is a patient reported outcome, comprises of 7 questions for anxiety and 7 questions for depression, with each answer graded from 0 to 3 with a higher score indicating a worse condition. For each group of questions, scores of 7 or less indicate cases without anxiety or depression, whereas scores of 8 to 10, 11 to 14, and 15 to 21 indicate mild, moderate, and severe cases, respectively.

The C-SSRS, Investigator-administered version, was designed to provide a prospective, standardized measure of suicidality. C-SSRS is administered in the form of a clinical interview. The C-SSRS categories have been re-ordered from the actual scale to facilitate the definitions of the endpoints, and to enable clarity in the presentation of the results: Category 1 - Wish to be Dead, Category 2 - Non-specific Active Suicidal Thoughts, Category 3 - Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act, Category 4 - Active Suicidal Ideation with Some Intent to Act, without Specific Plan, Category 5 - Active Suicidal Ideation with Specific Plan and Intent, Category 6 - Preparatory Acts or Behavior, Category 7 - Aborted Attempt, Category 8 - Interrupted Attempt, Category 9 - Actual Attempt (non-fatal), Category 10 - Completed Suicide.
