Trial Outcomes & Findings for A Phase 2 Efficacy and Safety Study of Dapirolizumab Pegol (DZP) in Systemic Lupus Erythematosus (NCT NCT02804763)

NCT ID: NCT02804763

Last Updated: 2021-06-30

Results Overview

The primary efficacy variable was assessed by establishing if there was a dose response relationship between BICLA response at Week 24 and dose, using Multiple Comparison Procedure - Modelling (MCP-Mod). Four candidate dose-response models were evaluated: a linear model, a logistic model, and 2 Emax models, and the MCP-Mod methodology controlled for multiplicity. BICLA response was defined as meeting all of the following criteria: 1. BILAG 2004 improvement: A scores at Baseline improved to B, C or D; B scores improved to C or D; no new A scores and ≤ 1 new B. 2. No worsening in Systemic Lupus Erythematosus Activity Index 2000 (SLEDAI-2K), defined as no increase in SLEDAI-2K total score. 3. No worsening in Physician's Global Assessment of Disease Activity (PGA), defined as \< 10 millimeter (mm) increase on a 100 mm visual analog scale (VAS). 4. No disallowed changes in concomitant medications, mainly including increases in corticosteroids, immunosuppressants, and antimalarials.

PRIMARY outcome

Timeframe: Week 24

Population: The Full Analysis Set (FAS) consisted of all participants in the Randomized Set with the exception of 1 study participant who received less than 1 full dose during the study and 5 study participants who were randomized at Site 321. Missing values were imputed using a modified non-responder imputation (mNRI).

The primary efficacy variable was assessed by establishing if there was a dose response relationship between BICLA response at Week 24 and dose, using Multiple Comparison Procedure - Modelling (MCP-Mod). Four candidate dose-response models were evaluated: a linear model, a logistic model, and 2 Emax models, and the MCP-Mod methodology controlled for multiplicity. BICLA response was defined as meeting all of the following criteria: 1. BILAG 2004 improvement: A scores at Baseline improved to B, C or D; B scores improved to C or D; no new A scores and ≤ 1 new B. 2. No worsening in Systemic Lupus Erythematosus Activity Index 2000 (SLEDAI-2K), defined as no increase in SLEDAI-2K total score. 3. No worsening in Physician's Global Assessment of Disease Activity (PGA), defined as \< 10 millimeter (mm) increase on a 100 mm visual analog scale (VAS). 4. No disallowed changes in concomitant medications, mainly including increases in corticosteroids, immunosuppressants, and antimalarials.

Population: The Safety Set (SS) consisted of all study participants who were randomized and received at least 1 dose (any amount) of study drug.

An AE was any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment. An adverse event (AE) was therefore any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. All AEs that occurred during the study were considered related unless clearly unrelated.
