We report feasibility and efficacy of PET-guided BrECADD as first-line treatment in older patients with AS-cHL.Patients with AS-cHL aged 61-75 years were enrolled in a phase II single-arm cohort of the HD21 trial (ClinicalTrials.gov identifier: NCT02661503). Patients with negative PET/computed tomography after 2×BrECADD (PET2) received a total of 4×BrECADD, while PET2-positive patients received 6×BrECADD. The primary end point was the centrally reviewed complete remission (CR) rate after the end of chemotherapy (EOC). Secondary end points included feasibility, adverse events, treatment-related morbidity (TRMB), progression-free survival (PFS), overall survival (OS), and health-related quality of life (HRQoL).Between June 2020 and April 2023, 85 patients were enrolled, of whom 83 with a median age of 67 years (range, 61-75) were analyzed in the intention-to-treat cohort. Most prevalent ≥grade 3 toxicities included leukopenia (n = 80 $[96\%]),$ thrombocytopenia (n = 71 $[86\%]),$ anemia (n = 57 $[69\%]),$ and febrile neutropenia (n = 46 $[55\%]).$ Forty-eight $(60\%)$ of 80 patients with centrally reviewed PET2 were scheduled for 4×BrECADD and 32 $(40\%)$ for 6×BrECADD. Of these, 71 patients $(89\%)$ received the target number of cycles. Sixty-eight patients $(82\%;$ $95\%$ CI, 72 to 90) achieved CR at EOC. PFS and OS estimates at 2 years were $91.5\%$ $(95\%$ CI, 85 to 98) and $90.8\%$ $(95\%$ CI, 84 to 98), respectively. No death was attributed to study treatment. Initially, impaired HRQoL scores improved during follow up and on average reached population reference values.PET-guided BrECADD in older patients is feasible and effective. With a PFS rate on par with that of younger patients, short duration, and limited anthracycline exposure, BrECADD is a valuable treatment option also for older patients with AS-cHL.}, cin = {ED01}, ddc = {610}, cid = {I:(DE-He78)ED01-20160331}, pnm = {899 - ohne Topic (POF4-899)}, pid = {G:(DE-HGF)POF4-899}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:40674676}, doi = {10.1200/JCO-25-00439}, url = {https://inrepo02.dkfz.de/record/302998}, }
