Brentuximab Vedotin Should be the Second Line Regimen of Choice for Recurrent Hodgkin Lymphoma Prior to Stem Cell Transplant Catherine Diefenbach, MD Assistant Professor of Medicine NYU Perlmutter Cancer Center, NYU Langone Medical Center
Hodgkin Lymphoma Most common lymphoma in the young. Median age at dx: 39yrs 40 % of patients younger than 40. 75% cured with frontline chemotherapy or chemo-radiotherapy. From Dorothy Reed, 1902
Why Does Relapsed Hodgkin Lymphoma Matter? 25% of patients relapse or have primary refractory dz. These are young patients. ASCT curable in only 50% of patients. No other established curative salvage therapy. Median TTP with relapse after SCT treated with subsequent therapy is 3.8 months Median survival is 26 months.
3 Key Questions in Relapsed HL How do we maximize cure? How do we minimize toxicity? How do we maximize quality of life during therapy?
Conventional Chemotherapy: The Existing Paradigm Do existing regimens for first salvage Rx – Maximize cure - – Minimize toxicity - – Are they convenient? - – Are they cost-effective? - – Can we do better? - NO YES
Survival for Patients Relapsed After Transplant Median PFS 1.3 years. 71% of relapses occurred within 1 year after ASCT. Equally distributed in the following periods: – < 3 months (22%) – > 3 months and < 6 months (22%) – > 6 and < 12 months (27%)
Maximizing Transplant Related Benefit Achieving a before ASCT most important factor in determining long-term DFS. Other post transplant prognostic factors. – Duration of initial remission – Extent of disease at relapse – Constitutional symptoms CR
MAXIMIZING DISEASE CONTROL PRIOR TO TRANSPLANT WILL MAXIMIZE BENEFIT (CURE) FROM TRANSPLANT.
Response Data Brentuximab Second Line ORR 85.7% CR = 50% PR = 35.7% SD = 7.1% POD 7.1% ICE CR = 26% DHAP CR = 21% GVD CR = 19% Compared to
BRENTUXIMAB IS SIGNIFICANTLY LESS TOXIC THEN CONVENTIONAL SALVAGE Rash is ONLY Grade 3-4 toxicity No Gr3 cytopenias No febrile neutropenia Growth factors support not required Administered outpatient
Successful ASCT after Brentuximab Median cell dose collected 5.87 x 10 6 CD34+ cells. Median time to reach collection = 1 day Median time to neutrophil engraftment 10 days (10- 11) Median time to platelet engraftment 11 days (10-13)
Brentuximab Related Toxicities Only 1 Gr 3 toxicity for Brentuximab No neutropenia No fevers No thrombocytopenia Administered outpatient
ICE vs. Brentuximab ICE 3 year EFS 22% 10 month DFS 92% ICE Brentuximab
Conclusions Maximizing disease control prior to ASCT will maximize cure from ASCT Brentuximab Vedotin –N–Novel Agent –H–High ORR and High CR rate –L–Low toxicity –O–Outpatient administration Conventional chemotherapy: –F–Fails to provide a high CR rate –F–Fails to provide long term disease control –H–Has unacceptable toxicity –R–Requires hospitalization
