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.
