简要总结
This is a single arm, open label, multi-center prospective study to explory the safety and efficacy of GC012F CAR-T cells in patient diagnosed with high-risk chromosomal abnormalities BCMA+ multiple myeloma(MM).
详细描述
The main aim of this study is to determin the safety and efficacy of GC012F in cytogenetic high-risk MM. GC012F is an autologus dual chimeric antigen receptor T-cell(CAR-T) therapy that targets B-cell maturation antigen(BCMA) and CD19. This study comprises of a screening phase(less than or equal to 28 days prior to apheresis) followed by apheresis(will occur upon enroiiment); Treatment Phase including autologus stem cell transplant on Day-1 followed by infusion of GC012F on Day0 and then post-infusion assessments from Day1 to Day 84; and a Post-treatment Phase(Day 85 and up to end of the study). Efficacy will be explored to assessed and safety will be closely monitored during the study.
