ListOutcomeTime frameDescription
PrimaryPercentage of Participants Who Achieve a PPPASI-50 at Week 16At Week 16
PPPASI-50 is defined as \>= 50 percent decrease in PPPASI total score from baseline. PPPASI is a disease-specific efficacy assessment tool to evaluated for 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease.
SecondaryPercentage of Participants Who Achieve a PPPASI-50 at All Other Visits in Placebo-controlled PhaseWeeks 2 to 14
PPPASI-50 is defined as \>= 50 percent decrease in PPPASI total score from baseline. PPPASI is a disease-specific efficacy assessment tool to evaluated for 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease. Missing values at were imputed using non-responder imputation (NRI) as the primary method, by which a participant without sufficient data for the response determination was considered a non-responder.
SecondaryPercentage of Participants Who Achieve a PPPASI-75 at Each Visit in Placebo-controlled PhaseWeeks 2 to 16
PPPASI-75 is defined as \>=75 percent decrease in PPPASI total score from baseline. PPPASI is a disease-specific efficacy assessment tool to evaluated for 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease. Missing values were imputed using NRI as the primary method, by which a participant without sufficient data for the response determination was considered a non-responder.
SecondaryArea Under the Curve (AUC) of PPPASI Total Score From Baseline Through Week 16Baseline to Week 16
The AUC for PPPASI total score from baseline through Week 16 is the sum of the AUCs in each time interval specified by the dates of the visits and is calculated based on the linear trapezoidal method. PPPASI is a disease-specific efficacy assessment tool to evaluate 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease.
SecondaryPercent Change From Baseline in PPPASI Total Score by Visit in Placebo-controlled Phase .Baseline to Week 16
PPPASI is a disease-specific efficacy assessment tool to evaluated for 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease. A positive change from baseline indicates a worsening of symptoms.
SecondaryChange From Baseline in PPPASI Total Score at Week 16Baseline and Week 16
PPPASI is a disease-specific efficacy assessment tool to evaluated for 3 signs of the disease (erythema, pustules/vesicle and desquamation/scale) as sub-scores on palms or soles. The PPPASI total scores are calculated by sum of the sub-scores and range from 0 to 72 with a higher score indicating more severe disease. Change from baseline based on a mixed-effects model for repeated measures with a positive change indicating a worsening of symptoms.
SecondaryAUC for PPSI Total Score From Baseline Through Week 16Baseline to Week 16
The AUC for PPSI total score from baseline through Week 16 is the sum of the AUCs in each time interval specified by the dates of the visits and is calculated based on the linear trapezoidal method. PPSI is a disease-specific assessment tool for grading the severity of PPP lesions. Evaluation of skin lesion sites are assessed separately for erythema, pustules/vesicle and desquamation/scale, which are each rated on a scale of 0 to 4. The PPSI produces a total numeric score that ranges from 0 to 12. A higher score indicates more severe disease.
SecondaryPercent Change From Baseline in PPSI Total Score by Visit in Placebo-controlled PhaseBaseline to Week 16
PPSI is a disease-specific assessment tool for grading the severity of PPP lesions. Evaluation of skin lesion sites are assessed separately for erythema, pustules/vesicle and desquamation/scale, which are each rated on a scale of 0 to 4. The PPSI produces a total numeric score that ranges from 0 to 12. A higher score indicates more severe disease. A positive change from baseline indicates a worsening of symptoms.
SecondaryChange From Baseline in PPSI Total Score at Week 16Baseline and Week 16
PPSI is a disease-specific assessment tool for grading the severity of PPP lesions. Evaluation of skin lesion sites are assessed separately for erythema, pustules/vesicle and desquamation/scale, which are each rated on a scale of 0 to 4. The PPSI produces a total numeric score that ranges from 0 to 12. A higher score indicates more severe disease. Change from baseline based on a mixed-effects model for repeated measures with a positive change indicating a worsening of symptoms.
SecondaryPercentage of Participants Achieving a PGA Score of Clear (0) or Minimal (1) by Visit in Placebo-controlled PhaseWeeks 2 to 16
The PGA for palms and soles was used to determine the participants PPP lesions on palms and soles. Lesions on palms and soles were graded based on the following scales: 0 = Clear 1. = Almost clear/Minimal 2. = Mild 3. = Moderate 4. = Severe 5. = Very severe. The percentage of of participants with a post baseline score of 0 or 1 (responders) are reported. Missing values at were imputed using NRI as the primary method, by which a participant without sufficient data for the response determination was considered a non-responder.
