Therapy of Antibody-mediated Autoimmune Diseases by Bortezomib (TAVAB) (TAVAB)

November 29, 2019 updated by: Andreas Meisel, Charite University, Berlin, Germany
The aim of this pilot study is to investigate the application of proteasome inhibitor Bortezomib (Velcade®, approved for therapy of multiple myeloma) in patients with therapy-refractory antibody-mediated autoimmune diseases. The investigators hypothesis is that the proteasome inhibition will lead to reduced antibody titers and improved clinical outcome.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
change in disease specific antibody titers after application of Bortezomib
Time Frame: 6 months after end of therapy (6 weeks) compared to baseline (before therapy)
Change in disease specific antibody titers (anti-ACh for myasthenia gravis, anti-dsDNA for systemic lupus erythematosus, anti-ACPA for rheumatoid arthritis) 6 months after end of Bortezomib therapy (duration 6 weeks) compared to baseline (before therapy).
6 months after end of therapy (6 weeks) compared to baseline (before therapy)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
