A Study to Test How Effective and Safe Different Doses of BI 655130 Are in Patients With a Moderate to Severe Form of the Skin Disease Palmoplantar Pustulosis

Boehringer Ingelheim152 enrolled

Overview

The primary objective is to provide dose-ranging data for 4 dose regimens of BI 655130 compared to placebo on the primary endpoint of percentage change from baseline in PPP ASI at Week 16. The target dose(s) will be estimated from the model by incorporating information on the minimum clinically relevant effect and accounting for safety. Supportive dose-ranging assessments will also be done on pre-specified secondary endpoints.

Primary Outcomes

The Percentage Change in Palmoplantar Pustulosis Area and Severity Index (PPP ASI) at Week 16 From Baseline

The percentage change in PPP ASI at Week 16 from baseline. The PPP ASI is a tool that provides a numeric scoring for patients overall PPP disease state, ranging from 0 (best) to 72 (worst). It is a linear combination of the percent of surface area of skin that is affected on the palms and soles of the body and the severity of erythema, pustules, and scaling (desquamation): The percent change from baseline is calculated as (PPP ASI current - PPP ASI baseline) / PPP ASI baseline \* 100%. Least square (LS) means, differences and confidence intervals were estimated by (Restricted maximum likelihood)-based Mixed effect model for repeated measurements (MMRM) including the fixed, categorical effects of treatment at each visit, region and the continuous effect of baseline at each visit as well as random effects of subject. Values post rescue medication or 6 weeks following last study treatment before discontinuation were censored. Unstructured covariance matrix was used.

Time frame: week 0 (baseline) and week 16

Secondary Outcomes

Change From Baseline in Palmoplantar Pustulosis Pain Visual Analogue Scale (VAS) Score at Week 4

Change from baseline in Palmoplantar Pustulosis Pain Visual Analogue Scale (VAS) score at Week 4. The PPP Pain VAS is a unidimensional measure of pain intensity due to palmoplantar pustulosis on palms and/or soles. It is a continuous scale comprised of a horizontal or vertical line, 10 centimeters (cm) in length, anchored by word descriptors at each end (score ranges from "no pain" at 0 cm to "very severe pain" at 10 cm). The patient was asked to place a vertical ( \| ) mark on the horizontal line to indicate the severity of the pain. Least square (LS) means, differences and confidence intervals were estimated by (Restricted maximum likelihood)-based MMRM including the fixed, categorical effects of treatment at each visit, region and the continuous effect of baseline at each visit as well as random effects of subject. Values post rescue medication or 6 weeks following last study treatment before discontinuation were censored. Unstructured covariance matrix was used.

Time frame: week 0 (baseline) and week 4.

It is a continuous scale comprised of a horizontal or vertical line, 10 centimeters (cm) in length, anchored by word descriptors at each end (score ranges from "no pain" at 0 cm to "very severe pain" at 10 cm). The patient was asked to place a vertical ( \| ) mark on the horizontal line to indicate the severity of the pain.

Time frame: week 0 (baseline) and week 16.

Palmoplantar Pustulosis Severity Index (PPP SI) Change From Baseline at Week 16

PPP SI change from baseline at Week 16. The PPP SI is based on the severity score of individual components (erythema, pustules, and scaling/desquamation) of PPP ASI assessments. The most severely affected area based on pustules was identified by the investigator at baseline and assessed at all subsequent visits. The PPP SI was calculated by summing up the individual components of PPP ASI assessment (range 0 (best) to 12 (worst)) at each visit for the identified location. Least square (LS) means, differences and confidence intervals were estimated by (Restricted maximum likelihood)-based Mixed effect model for repeated measurements (MMRM) including the fixed, categorical effects of treatment at each visit, region and the continuous effect of baseline at each visit as well as random effects of subject. Values post rescue medication or 6 weeks following last study treatment before discontinuation were censored. Unstructured covariance matrix was used.

Time frame: week 0 (baseline) and week 16.

Number of Patients Achieving a 50% Decrease From Baseline in Palmoplantar Pustulosis Area and Severity Index Score at Week 16 (PPP ASI50)

Number of patients achieving a 50% decrease from baseline in Palmoplantar Pustulosis Area and Severity Index score at week 16 (PPP ASI50). The PPP ASI is an investigator assessment of the extent and severity of palmoplantar pustulosis lesions on the palms and soles in PPP patients. This tool provides a numeric scoring for patients overall PPP disease state, ranging from 0 (best) to 72 (worst). It is a linear combination of the percent of surface area of skin that is affected on the palms and soles of the body and the severity of erythema, pustules, and scaling (desquamation). When (PPP ASI baseline - PPP ASI current)/ PPP ASI baseline \* 100% \>= 50%, PPP ASI50 = 1.

Time frame: week 0 (baseline) and week 16

Number of patients achieving a 75% decrease from baseline in Palmoplantar Pustulosis Area and Severity Index score at week 16 (PPP ASI75). The PPP ASI is an investigator assessment of the extent and severity of palmoplantar pustulosis lesions on the palms and soles in PPP patients. This tool provides a numeric scoring for patients overall PPP disease state, ranging from 0 (best) to 72 (worst). It is a linear combination of the percent of surface area of skin that is affected on the palms and soles of the body and the severity of erythema, pustules, and scaling (desquamation). When (PPP ASI baseline - PPP ASI current)/ PPP ASI baseline \* 100% \>= 75%, PPP ASI75 = 1.

Time frame: week 0 (baseline) and week 16

Number of Patients With Palmoplantar Pustulosis Physician Global Assessment (PPP PGA) Clear/Almost Clear (0 or 1) at Week 16

Number of patients with Palmoplantar Pustulosis Physician Global Assessment (PPP PGA) clear/almost clear (0 or 1) at Week 16. The PPP PGA relies on investigator assessment of the patient's skin presentation on the palms and soles. The investigator scored the individual components (erythema, pustules, and scaling/crusting) from 0 (best) to 4 (worst) as clear, almost clear, mild, moderate or severe. PPP PGA categorization is based on the mean of the four individual components.
