A Study to Evaluate the Effect of Deucravacitinib on Quality of Life in Participants With Plaque Psoriasis in a Community Setting

Dermatology Life Quality Index (DLQI) is a participant-reported Quality of Life (QoL) survey which consists of 10 questions concerning symptoms and feelings, daily activities, leisure, work, school, personal relationships, and treatment during the last week. Each question is scored on a 4-point scale:

0=not at all

• a little
• a lot
• very much The scores are added up to give a total score between 0 and 30. A lower total score means a better quality of life.

The Dermatology Life Quality Index (DLQI) is a simple, 10-question survey used to measure the impact of skin conditions on a patient's quality of life. It assesses how much a skin condition affects various aspects of daily life, including symptoms, feelings, daily activities, work or school, personal relationships, and treatment.

The DLQI is scored by summing the responses to its 10 questions. Each question is scored on a scale from 0 to 3:

0 = Not at all

• = A little
• = A lot
• = Very much The total score ranges from 0 to 30, with higher scores indicating a greater impact on the patient's quality of life.

The whole-body itch Numerical Rating Scale (NRS) is a survey that participants fill out themselves. It uses an 11-point scale from 0 to 10, where 0 means 'no itch' and 10 means 'worst itch imaginable.' Participants indicate the severity of their itching from psoriasis by selecting the number that best describes the worst level of itching they experienced in the past 24 hours. A lower score means better outcomes, indicating less severe itching.

The Static Physician's Global Assessment (s-PGA) is a 5-point scale to evaluate the average severity of all psoriatic lesions based on redness, scaling, and thickness. The s-PGA measures psoriasis severity at a single point in time, without considering the initial condition. The scale rates the severity as clear (0), almost clear (1), mild (2), moderate (3), or severe (4). A lower score means better outcomes, indicating less severe psoriasis.

An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a clinical investigation participant administered study treatment that does not necessarily have a causal relationship with this treatment.

Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, and requires inpatient hospitalization or causes prolongation of existing hospitalization.

Number of participants with laboratory abnormalities in potential drug-induced liver injury tests.

ALT=Alanine aminotransferase AST=Aspartate aminotransferase ULN=Upper limit of normal

Blood samples were collected to assess the abnormalities in laboratory parameters. The laboratory parameters were graded by Common Terminology Criteria for Adverse Events (CTCAE). Grade 3=Severe; Grade 4=Life-threatening.

Number of participants with abnormalities in vital signs including heart rate, systolic blood pressure, and diastolic blood pressure.

Vital Sign Measurements include: Body Temperature (C), Respiratory Rate (breaths/min), Seated Blood Pressure (mmHg) and Heart Rate (beats/min).

Clinically significant changes in these measurements may need medical attention as they could indicate a potential health concern.
