Tislelizumab, Gemcitabine and Cisplatin for R/R Hodgkin Lymphoma Followed by Tislelizumab Consolidation in Patients in Metabolic Complete Remission

"All patients will receive 2 cycles of gemcitabine and cisplatin (GP) + tislelizumab. Each cycle lasts 21 days. Treatment is given through an IV line on day 1 and 8.~After 2 cycles a FDG-PET-CT scan will be performed. Patients who respond well will proceed with 2 additional cycles of GP + tislelizumab . Patients with insufficient response will stop with the study treatment and they will continue treatment according to local practice.~After 4 cycles of GP + tislelizumab another FDG-PET-CT scan will be performed. If this scan shows that the disease is under control (metabolic complete remission) patients will proceed with 13 cycles of tislelizumab consolidation treatment (21 day cycles). Treatment is given on day 1 through an IV line."
