E.5 End points |
E.5.1 | Primary end point(s) |
Percent change from baseline in Cutaneous Erythematosus Disease Area and Severity Index activity (CLASI-A) sub-score: The Cutaneous Erythematosus Disease Area and Severity Index (CLASI) is a clinician rated scale composed of 56 items designed to assess the disease activity and damage in CLE in adults. The disease activity (CLASI-A) sub-score ranges from 0 to 70: 0–9 indicating mild disease, 10–20 indicating moderate disease, and 21–70 indicating severe disease. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1-Proportion of patients with physician’s global assessment of disease activity (PhysGA – disease activity) of 0 or 1 (disease free or almost disease free): The PhysGA-disease activity is a 5 point-Lickert scale instrument designed to assess physician-reported disease activity ranging from “Not active at all” to “Extremely active”.
2-Change from baseline in patients reported daily worst itch using Peak Pruritus Numerical Rating Scale (itch-NRS): The itch-NRS is a single item patient-reported outcome (PRO) tool that patients will use to report the intensity of their pruritus (itch) during a daily recall period. Patients will be asked to rate their worst itch on a 0 (“No itch”) to 10 (“Worst itch imaginable”) NRS.
3-Change from baseline in patients reported daily worst pain using Peak Pain Numerical Rating Scale (Pain-NRS): The Pain-NRS is a single item PRO tool that patients will use to report the intensity of their CLE-related pain (skin, oral, genital) during a daily recall period. Patients will be asked to rate their worst pain on a 0 (“No pain”) to 10 (“Worst pain imaginable”) NRS.
4-Proportion of CLASI-A50 and CLASI-A75 responders: The CLASI-A50/75 response is defined as a patient achieved a decrease by at least 50%/75% of CLASI-A sub-score from baseline.
5-Change from baseline in CLASI components’ score: Change from baseline in CLASI components’ score over time
6-Proportion of patients with the Investigator’s global assessment for CLE (IGA-CLE) score of 0 or 1 (clear or almost clear): The IGA-CLE is a clinician reported outcome that allows for clinicians to assess the overall disease activity of CLE using a 5-point scale from 0 (clear) to 4 (severe).
7-Change from baseline in the Oral Health Impact Profile (OHIP-14) for patients with oral lesions at baseline: OHIP-14 is a PRO questionnaire measures people’s perception of dysfunction, discomfort and disability attributed to oral conditions in adults. It is composed of 14 items that assess seven different dimensions. The OHIP-14 scores can range from 0 to 56 and higher OHIP-14 scores indicate worse oral-health-related quality of life.
8-Change from baseline in SKINDEX-29+3 total score: Skindex-29 is a PRO measure designed to assess the effects of skin disease on patients' health-related quality of life in adults. It contains 29 items, distributed across 3 domains. Individual items are scored from 0 to100 in 25-point increments with 100 representing maximal disability. The Skindex 29+3 includes a fourth subscale (3 questions) to assess lupus-specific issues.
9-Total number of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs) and adverse events of special interest (AESIs)
10-Percent of TEAEs, SAEs and AESIs
11-Percent of potentially clinically significant abnormalities (PCSAs): Percent of potentially clinically significant abnormalities (PCSAs) in laboratory tests, electrocardiogram (ECG) or vital signs through end of study
12-SAR443122 plasma concentration
13-Assessment of pharmacokinetic (PK) parameter: Cmax: Maximum plasma concentration
14-Assessment of PK parameter: tmax: Time to reach Cmax
15-Assessment of PK parameter: AUC0-tau: Area under the plasma concentration - time curve over the dosing interval
16-Assessment of PK parameter: t1/2z : Elimination half-life |
