Trial Details


Mezigdomide is a cereblon E3 ligase modulator that doctor's think may work better at finding and killing myeloma cells. 
Teclistamab is a bispecific antibody that targets BCMA and CD3 on certain cells. 

You’ll get:
  • Mezigdomide – A pill that you take by mouth. The dose you'll get depends on when you start the trial and how safe it has been
  • Teclistamab –  The dose you'll get depends on when you start the trial and how safe it has been

You'll have biopsies to see how well the treatment is working. The clinical trial doctors will check your health for up to 2 years.

The Food and Drug Administration (FDA) has not yet approved mezigdomide.
