Clinical Trial Summary

A prospective, single-arm, open-label trial of deucravacitinib 6 mg daily in patients with PPP. All participants will receive deucravacitinib 6 mg daily for 24 weeks, with study visits every 4 weeks.

Description:

In the first stage, 8 patients will be accrued. If 2 or fewer patients achieve a ppPASI-50 in these 8 patients, the study will be stopped. Otherwise, 10 additional patients will be accrued for a total of 18.

Analysis Plan: Descriptive statistics will be used to characterize the study population, including demographics, disease characteristics and previous treatments. For the primary outcome, the percentage of participants who achieve a ppPASI-50 response, or at least 50% improvement in ppPASI score, at 16 weeks, the response rate with a 95% CI will be calculated. For all secondary endpoints, summary and descriptive statistics will be used as appropriate , including number of observations, calculation of mean/median, standard deviation range and 95% confidence intervals.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of participants who achieve a ppPASI-50 response, or at least 50% improvement in ppPASI score	The ppPASI is the most commonly used disease severity measure use in palmoplantar pustulosis clinic trials. The ppPASI is composed of subscores of erythema (E), pustules/vesicles (P), desquamation/scales (D) on the left (L) and right (R) palm (P) and sole (S) respectively. The PASI produces a numeric score that can range from 0 to 72, with higher PASI scores denoting more severe disease activity	16 weeks
Secondary	Proportion of participants who achieve a ppPASI-50 response, or at least 50% improvement in ppPASI score	The ppPASI is the most commonly used disease severity measure use in palmoplantar pustulosis clinic trials. The ppPASI is composed of subscores of erythema (E), pustules/vesicles (P), desquamation/scales (D) on the left (L) and right (R) palm (P) and sole (S) respectively. The PASI produces a numeric score that can range from 0 to 72, with higher PASI scores denoting more severe disease activity	Week 24
Secondary	Change from baseline in the Dermatology Quality Life Index (DLQI)	The DLQI is a dermatology-specific quality of life instrument to measure the impact of skin disease on different aspects of health-related quality of life. The questionnaire contains 10 questions, each scored on a 4-point Likert scale. The DLQI is calculated by adding the score of each question, resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired. A score higher than 10 indicates that the patient's life is being severely affected by their skin disease.	Week 16, Week 24
Secondary	Change from baseline in ppPASI	The ppPASI is the most commonly used disease severity measure use in palmoplantar pustulosis clinic trials. The ppPASI is composed of subscores of erythema (E), pustules/vesicles (P), desquamation/scales (D) on the left (L) and right (R) palm (P) and sole (S) respectively. The PASI produces a numeric score that can range from 0 to 72, with higher PASI scores denoting more severe disease activity	Week 16, Week 24
Secondary	Percentage of patient who achieve a Physicians Global Assessment Score of 0 or 1	The physician's global assessment is a widely used outcome measure that relies on physician visual assessment of disease severity. The static PGA determines psoriasis severity at a single point in time, without taking the baseline disease condition into clear (0), almost clear (1), mild (2), moderate (3), severe (4).	Week 16, Week 24
Secondary	Change from baseline in EQ-5D VAS	The EQ-5D is a validated, reliable, and responsive instrument widely used in clinical trials where respondents rate their health in each of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety depression. EQ-5D questionnaire also includes a Visual Analog Scale (VAS), by which respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).	Week 16, Week 24
Secondary	Change from baseline in the itch visual analogue scale (itch-VAS)	The VAS-itch is a 10 cm line on which patients mark their pruritus intensity on a scale from "no itch" (0 points) to "worst imaginable itch" (10 points). The VAS-itch can be interpreted as 0 - < 3 points represents mild pruritus, = 3 - 7 points moderate pruritus, = 7 - 9 points severe pruritus, and = 9 points severe pruritus	Week 16, Week 24
Secondary	Change from baseline in the pain visual analogue scale (pain-VAS)	The VAS-pain is a 10 cm line on which patients mark their pain on a scale from "no no" (0 points) to "worst imaginable pain" (100 points). The following cut points on the pain VAS have been recommended pain: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75 - 100 mm)	Week 16, 24
