CAR T-cell therapy less effective in transformed follicular lymphoma

Key clinical point: Chimeric antigen receptor (CAR) T-cell therapy produced durable responses in patients with relapsed/refractory follicular lymphoma (FL) but was less effective in patients with transformed FL (tFL).

Major finding: All complete responders with FL were still in remission at a median follow-up of 24 months, but the median duration of response was 10.2 months for patients with tFL.

Study details: Phase 1/2 trial including 8 FL patients and 13 tFL patients
