About this study

Official title: An Open-label, Non-comparative Clinical Study of the Safety, Pharmacokinetics, Immunogenicity BCD-256 and Divozilimab in Monotherapy and Combination Therapy With Single and Multiple Intravenous Administration to Subjects With Systemic Lupus Erythematosus

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).

Read the detailed description

The study is conducted in 2 stages which involve different subjects. Stage 1 of the study have a modified "3+3" design and involves dose escalation of BCD-256 in 1-3 cohorts with an interval of at least 14 days dose - limiting toxicicity (DLT) (DLT assessment period) between cohorts 1-3. In cohorts 4 and 5, the administration of divozilimab is carried out in parallel with cohorts 1-3. A decision on the possibility of starting Stage 2 and including new subjects in it will be made after approval by thethe Cohort Dosing Safety Committee (CDSC) of an interim report (for 12 weeks of therapy). Stage 2 of the study will involve the use of BCD-256 in combination with divozilimab in 4 cohorts, BCD-256 dose levels in cohorts will be determined based on the results of the main period of Stage 1 (for 12 weeks of therapy).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BCD-256 and Divozilimab in people with Systemic Lupus Erthematosus, run by Biocad at 1 site in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 51 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 22 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Anastasiia S Admakina, MD (+ 7 (931) 311 90 49, admakina@biocad.ru), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of subjects with adverse events (time frame: 85 days). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2025.
