a study evaluating safety and efficacy of c-car011 in subjects with b-nhl

Conditions: Refractory or Relapsed B-cell Non-Hodgkin Lymphoma

Summary: this is a single arm, single-center, non-randomized study to evaluate the safety and efficacy of c-car011 in relapsed or refractory b cell non-hodgkin lymphoma (nhl).

the study will include the following sequential phases: screening, pre-treatment (cell product preparation, lymphodepleting chemotherapy), treatment and follow-up.
