I was diagnosed with MM in December, 2013. Was treated with 6 lines of therapy but relapsed on each without having attained remission. In July of 2020 I entered a clinical trial using immunotherapy (tnb 383b) and amazingly achieved complete remission in a few weeks. During the 2.5 years in the clinical trial I remain in complete remission. I receive an infusion every 3 weeks and the infusion has been side-effect free as far as I can tell. I turn 79 in a few months. This treatment has been a blessing. The bi-specific antibody attacks the BCMA coating on myeloma cell wall by drawing my T cells to the myeloma cells so that my immune system can destroy the myeloma cells while leaving normal cells unscathed. So far so good!
