Abstract

Purpose: To evaluate safety and efficacy outcomes for subjects on the ECHELON-1 study treated in North America (NA). Patients and Methods: ECHELON-1 is a global, open-label, randomized phase III study comparing doxorubicin, vinblastine, and dacarbazine in combination with brentuximab vedotin (AþAVD) versus ABVD (AVD þ bleomycin) as first-line therapy in subjects with stage III or IV classical Hodgkin lymphoma (cHL; NCT01712490). Subjects were randomized 1:1 to receive AþAVD or ABVD intravenously on days 1 and 15 of each 28-day cycle for up to 6 cycles. Results: The NA subgroup consisted of 497 subjects in the AþAVD (n ¼ 250) and ABVD (n ¼ 247) arms. Similar to the primary analysis based on the intent-to-treat population, the primary endpoint [modified progression-free survival (PFS) per independent review] demonstrated an improvement among subjects who received AþAVD compared with ABVD (HR ¼ 0.60; P ¼ 0.012). For PFS, the risk of progression or death was also reduced (HR ¼ 0.50; P ¼ 0.002). Subsequent anticancer therapies were lower in the AþAVD arm. Grade 3 or 4 adverse events (AEs) were more common, but there were fewer study discontinuations due to AEs in the AþAVD arm as compared with ABVD. Noted differences between arms included higher rates of febrile neutropenia (20% vs. 9%) and peripheral neuropathy (80% vs. 56%), but lower rates of pulmonary toxicity (3% vs. 10%) in subjects treated with AþAVD versus ABVD. Conclusions: The efficacy benefit and manageable toxicity profile observed in the NA subgroup of ECHELON-1 support AþAVD as a frontline treatment option for patients with stage III or IV cHL.
