Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Myasthenia Gravis Systemic Lupus Erythematosus Rheumatoid Arthritis Drug: Bortezomib Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 11 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Therapy of Antibody-mediated Autoimmune Diseases by Bortezomib (TAVAB)
Study Start Date : October 2014
Actual Primary Completion Date : August 30, 2019
Actual Study Completion Date : August 30, 2019


Arm Intervention/treatment
Experimental: Bortezomib (Velcade) Drug: Bortezomib
Bortezomib will be subcutaneously applicated in 2 treatment cycles with 4 injections of 1.3 mg Bortezomib /m2 body surface per cycle.
Other Name: Velcade




Primary Outcome Measures :
  1. 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).


Secondary Outcome Measures :
  1. Change in disease specific antibody titer after Bortezomib application [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
    Change in disease specific antibody titer after Bortezomib application (except at time point 6 months after end of therapy = primary outcome measure)

  2. Change in quality of life (Qol score) [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
  3. Change in Activities of Daily Living (Adl score) [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
  4. change in dose of immunosuppressive co-medication [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
  5. Change in titers of protective antibodies (e.g. measles) [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
    Change in titers of protective antibodies against measles virus, rubella virus, varicella zoster virus, pneumococcus, cytomegalovirus

  6. Change in number of antibody producing plasmablasts/cells [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
    Change in number of antibody producing plasmablasts/cells in peripheral blood

  7. Change in concentration of soluble mediators (e.g. IL-6) [ Time Frame: at regular intervals up to 30 weeks compared to baseline ]
    Change in concentration of soluble mediators (e.g. IL-6) in peripheral blood

  8. need for hospitalisation [ Time Frame: at regular intervals up to 30 weeks ]
