Recruiting PHASE1 Systemic Lupus Erthematosus

Tests treatment safety and results for Systemic Lupus Erthematosus

Official title Safety, Pharmacokinetics, Immunogenicity BCD-256-1 and Divozilimab in Subjects With Systemic Lupus Erythematosus

ClinicalTrials.gov ID: NCT07136389

What this study is testing

What is BCD-256?

BCD-256 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for systemic lupus erthematosus.

Also referred to as Anti-BDCA2.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing: The goal of this clinical trial to investigate the safety, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary efficacy of BCD-256 alone and in combination with anti-CD20 therapy (divozilimab) as second- or later-line therapy in subjects with skin lesions due to mild to moderate systemic lupus erythematosus. The study consists of the first stage (cohorts 1-5) and the second stage (cohorts A - D).

Phase 1: an early, usually small safety study
