|---|---|---|---|
| Primary | Mean Change in the Total Improvement Score (TIS) From Start to End of Zetomipzomib (KZR-616) Treatment Period | 16 weeks in each Treatment Period (32 weeks total) | The primary efficacy endpoint was mean change from start to end of zetomipzomib (KZR-616) Treatment Periods in the Total Improvement Score (TIS), which ranges from 0 to 100 \[low of 0 to high of 100, where higher scores are better\]. Mean change in TIS was calculated by comparing the Baseline and post Baseline observations for patients in both KZR-616 treatment periods combined. Note: TIS scores for placebo treatment periods are presented in this outcome measure but were not included in the primary outcome measure analysis. |
| Secondary | Proportion of Patients With TIS Response | 16 weeks in each Treatment Period (32 weeks total) | The proportion of patients with an increase of ≥ 20 points on the TIS from start to end of zetomipzomib (KZR-616) treatment. TIS response is categorized by the following improvement thresholds: * Minimal response = TIS ≥ 20 * Moderate response = TIS ≥ 40 * Major response = TIS ≥ 60 This endpoint was assessed by comparing Week 16 versus Week 0 for patients allocated to Arm A and Week 32 versus Week 16 for patients allocated to Arm B. This re-baselining approach was utilized to maximize the precision for assessment of zetomipzomib effect in Arm B. |
| Secondary | Number of Patients Meeting the International Myositis Assessment and Clinical Studies Group (IMACS) Definition of Improvement (DOI) | 16 weeks in each Treatment Period (32 weeks total) | The IMACS DOI is ≥ 20% improvement in at least 3 of 6 core set activity measures, with no more than 2 core set activity measures (CSAMs) worsening by ≥ 25% (Manual Muscle Testing-8 Muscle Groups \[MMT-8\] could not be a worsening measure). |
| Secondary | Mean Percent Change From Baseline From Start to End of Treatment in the IMACS Individual CSAMs | 16 weeks in each Treatment Period (32 weeks total) | Mean percent change from baseline of the IMACS CSAMs consisting of: * Physician Global Assessment: physician assessment of patient's overall disease activity at present, high numbers indicate more severe disease activity \[0-10\] * Patient Global Assessments of Disease Activity: patient assessment of their overall disease activity at present, high numbers indicate more severe disease activity \[0-100\] * Manual Muscle Testing-8 Muscle Groups: scores range from 0 - 150, high scores are better * Health Assessment Questionnaire-Disability Index: scores range from 0 - 3, high scores are worse * Extramuscular Global Assessment of the Myositis Disease Activity Assessment Tool (2005 version): scores range from 0 - 10, high scores are worse * Muscle enzymes (clinical laboratory assessments \[CLA\]): Summarize the most abnormal CLA (creatine kinase \[CK\], aldolase, lactate dehydrogenase \[LDH\], alanine aminotransferase \[ALT\], or aspartate aminotransferase \[AST\]) at baseline, lower scores are better |
| Secondary | Mean Change in CDASI From Start to End of Zetomipzomib (KZR-616) Treatment | 16 weeks in each Treatment Period (32 weeks total) | Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) is a clinician scored single-page instrument that separately measures activity and damage, which consists of three (3) activity measures and two (2) damage measures which are assessed over 15 body areas. Scores range from 0-100 for activity and from 0-32 for damage, with higher scores indicating more severe disease. |
| Secondary | Mean Change in PP-NRS From Start to End of Zetomipzomib (KZR-616) Treatment | 16 weeks in each Treatment Period (32 weeks total) | The Peak Pruritus Numeric Rating Scale (PP-NRS) is used to evaluate severity of itch in DM patients. Scores range from 0-10, with zero (0) representing no itch and ten (10) representing the worst itch imaginable within a 24-hour recall period. |
| Secondary | PK of Zetomipzomib [KZR-616] (Cmax) | Up to 5 hours | This is the maximum observed plasma concentration (Cmax) observed after administration of the first dose of KZR-616 (either Week 0 or Week 16). The pharmacokinetic (PK) parameters were calculated using all timepoints at which the concentration was measured, ie. pre-dose and 30 minutes, and 4 hours post-dose, with an additional sample obtained at 0.25, 1, or 2 hours post-dose. |
| Secondary | PK of Zetomipzomib [KZR-616] (Tmax) | Up to 5 hours | This is the time to maximum observed plasma concentration (tmax) observed after administration of the first dose of KZR-616 (either Week 0 or Week 16). The PK parameters were calculated using all timepoints at which the concentration was measured, ie. predose and 30 minutes, and 4 hours postdose, with an additional sample obtained at 0.25, 1, or 2 hours postdose. |
| Secondary | PK of Zetomipzomib [KZR-616] (AUC) | Up to 5 hours | This is the area under the curve (AUC) from predose through 4 hour postdose observed after administration of the first dose of KZR-616 (either Week 0 or Week 16). The PK parameters were calculated using all timepoints at which the concentration was measured, ie. predose and 30 minutes, and 4 hours postdose, with an additional sample obtained at 0.25, 1, or 2 hours postdose. |
| Secondary | PK of KZR-59587 (Cmax) | Up to 5 hours | This is the maximum observed plasma concentration of KZR-59587 (Cmax) observed after administration of the first dose of KZR-616 (either Week 0 or Week 16). The pharmacokinetic (PK) parameters were calculated using all timepoints at which the concentration was measured, ie. pre-dose and 30 minutes, and 4 hours post-dose, with an additional sample obtained at 0.25, 1, or 2 hours post-dose. |
