A Phase 2b Dose Ranging Study to Evaluate the Efficacy and Safety of Rozibafusp Alfa (AMG 570) in Subjects With Active Systemic Lupus Erythematosus (SLE) With Inadequate Response to Standard of Care (SOC) Therapy
A Phase 2b Dose Ranging Study to Evaluate the Efficacy and Safety of Rozibafusp Alfa (AMG 570) in Subjects With Active Systemic Lupus Erythematosus (SLE) With Inadequate Response to Standard of Care (SOC) Therapy
The purpose of this study is to determine if Rozibafusp Alfa could be a useful therapeutic agent in the current treatment landscape where subjects with SLE have ongoing disease activity despite treatment with standard of care therapies.
This is a Bayesian adaptive phase 2b, multi-center, double-blind, randomized, placebo-controlled, 52-week, dose-ranging study in subjects with active SLE and inadequate response to SOC therapies including oral corticosteroids (OCS), immunosuppressants and immunomodulators. Previous biologic use is allowed with an adequate washout period.
Inclusion Criteria Screening Visit:
Subject has provided informed consent prior to initiation of any study-specific activities/procedures.
Age ≥ 18 years to ≤ 75 years at screening visit.
Fulfills classification criteria for SLE according to the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for SLE (Aringer et al, 2019), with antinuclear antibody ≥ 1:80 by immunofluorescence on Hep-2 cells being present at screening.
Hybrid SLEDAI score ≥ 6 points with a "Clinical" hSLEDAI score ≥ 4 points. The "Clinical" hSLEDAI is the hSLEDAI assessment score without the inclusion of points attributable to laboratory results, including urine or immunologic parameters.
Additional protocol-specific rules are applied at screening and throughout the study, as follows:
Unless there is a documented intolerance, subjects must be taking:
OR
• 2 of the above-mentioned SLE treatments in which 1 must be anti-malarial (hydroxychloroquine, chloroquine, or quinacrine).
