autologous cd30.car-t in combination with nivolumab in chl patients after failure of frontline therapy

Conditions: Classical Hodgkin Lymphoma; Hodgkin Disease Refractory; Hodgkin Disease Recurrent

Summary: this is a phase 1b, multicenter, open-label, single arm study to evaluate the safety and efficacy of the combination therapy, cd30.car-t and the programmed cell death protein-1 (pd-1) checkpoint inhibitor, nivolumab, in patients aged 12 years of age and above with relapsed or refractory classical hodgkin lymphoma (chl) following failure of standard frontline therapy.

upon successful leukapheresis to produce cd30.car-t cells, patients will enter the treatment phase of the study. treatments will include 4 cycles of nivolumab and cd30.car-t infusion (preceded by lymphodepletion chemotherapy). patients will then enter the post-treatment follow-up phase of the study, whereby patients will undergo either autologous stem cell transplant or continue to receive up to 6 additional treatment cycles of nivolumab. patients will be followed for response assessments and safety monitoring until end of study (eos); approximately 3 years after leukapheresis. long-term follow-up will continue with additional safety monitoring and survival for up to 15 years after leukapheresis.
