Legend Biotech Begins Phase 1 Clinical Trial in the US to Evaluate Investigational Anti-CD4 CAR-T Therapy for Relapsed or Refractory T-Cell Lymphoma
The Phase 1 trial is being led by Dr.
“We are excited by the promise of LB1901, and we look forward to further evaluating the safety and tolerability of LB1901. Determining the optimal dose for subsequent evaluation is one of the key objectives of this trial,” said Dr.
T-cell lymphoma is a heterogeneous group of lymphoid malignancies that account for less than 15 percent of non-Hodgkin’s lymphoma cases in the US.i,ii PTCL comprises subtypes that are uncommon and often aggressive, with a 5-year overall survival of only 39%.iii,iv CTCL are a group of T-cell malignancies that occur primarily in the skin.v Despite current treatment options, a substantial proportion of patients with PTCL or CTCL experiences relapse. A high unmet medical need remains for patients with relapsed or refractory PTCL and CTCL.
About the Clinical Development Program
LB1901-TCL-001 (NCT04712864) is a Phase 1 open-label, multicenter study of LB1901 in patients with histologically confirmed CD4+ RR PTCL (PTCL not otherwise specified, or PTCL-NOS, and angioimmunoblastic T cell lymphoma, or AITL) or RR CTCL (mycosis fungoides and Sézary syndrome). The primary objectives are to characterize the safety and tolerability of LB1901 and determine the optimal dose.
