ASH: A+AVD Beats ABVD for Advanced Hodgkin's Lymphoma
Lower combined risk of progression, death, or noncomplete response with A+AVD
MONDAY, Dec. 11, 2017 (HealthDay News) -- For patients with advanced-stage Hodgkin's lymphoma, brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) have superior efficacy to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), according to a study published online Dec. 10 in the New England Journal of Medicine to coincide with the annual meeting of the American Society of Hematology, held from Dec. 9 to 12 in Atlanta.
Joseph M. Connors, M.D., from the British Columbia Cancer Agency in Vancouver, Canada, and colleagues conducted a phase 3 trial involving patients with previously untreated stage III or IV classic Hodgkin's lymphoma. A total of 664 patients were assigned to receive A+AVD and 670 were assigned to receive ABVD.
The researchers found that the two-year progression-free survival rates were 82.1 and 77.2 percent in the A+AVD and ABVD groups at a median follow-up of 24.9 months (hazard ratio for an event of progression, death, or modified progression, 0.77; 95 percent confidence interval, 0.60 to 0.98; P = 0.03). There were 28 and 39 deaths with A+AVD and ABVD (hazard ratio for interim overall survival, 0.72; 95 percent confidence interval, 0.44 to 1.17; P = 0.19). There was a trend in favor of A+AVD for all secondary efficacy end points.
"A+AVD had superior efficacy to ABVD in the treatment of patients with advanced-stage Hodgkin's lymphoma, with a 4.9 percentage-point lower combined risk of progression, death, or noncomplete response and of subsequent anticancer therapy at two years," the authors write.
The study was funded by Millennium Pharmaceuticals, a wholly owned subsidiary of Takeda Pharmaceuticals, and Seattle Genetics.
