Clinical Hold on Legend Bio CAR-T Therapy

FDA has placed a clinical hold against Legend Biotech and its Phase 1 clinical trial for LB1901, an investigational autologous chimeric antigen receptor T-cell therapy targeting malignant CD4+ T-cells for treating adults with relapsed or refractory T-cell lymphoma. The agency notified the company by email and indicated an official clinical hold letter will be sent by 3/11.
