Advanced Hodgkin Lymphoma Clinical Trial
Official title:
Very Early PET-response Adapted Targeted Therapy for Advanced Hodgkin Lymphoma: a Single -Arm Phase II Study
The main objective of this trial is to assess whether treatment adaptation based on a very early FDG-PET/CT results in improved efficacy while minimizing treatment toxicity in advanced stage Hodgkin Lymphoma (HL) patients treated with brentuximab vedotin (BV)-containing regimens.
This single-arm phase II study investigates the value of early FDG-PET-response adapted BV-based therapy for advanced HL. All patients will receive one cycle of BrAVD followed by an FDG-PET/CT. Patients with a negative early FDG-PET(Deauville score 1-3) will continue with five more BrAVD cycles (total six cycles) while patients with a positive FDG-PET should shift to six cycles of BrECADD. The hypothesis is that the efficacy will be comparable to the efficacy of BEACOPPesc and BrECADD, while using the intensive chemotherapy regimen only for those patients who do not achieve a negative FDG-PET after one cycle. The choice to assess the treatment sensitivity by PET after a single cycle of BrAVD is based on results from a recent international multicenter study comparing FDG-PET/CT after one and two cycles of ABVD chemotherapy in HL. There is no reason to suspect that FDG-PET1 should be less prognostic after BrAVD than after ABVD. With this trial, the investigators believe they can add important information about the optimal treatment of BV-containing first-line treatment for advanced HL, and thus answer important therapeutic questions that are likely to otherwise remain unanswered even after the Echelon-1 and HD21 trials reach mature results. This relatively large single-arm phase II trial of 150 patients will allow a meaningful comparison with the BrAVD and BrECADD regimens based on modified progression-free survival (primary endpoint) and progression-free survival (secondary endpoint) respectively. ;
